INTRODUCTION The word spelling can evoke images of classroom drill and testing, children writing strings of letters as a teacher pronounces words ever so clearly. In parts of the United States, it can also bring an image of specialized wizardry and schoolroom competition, the spelling bee. For countless adults, who confess with self-deprecation to being terrible spellers, it is a reminder of a mysterious but minor affliction that the fates have visited on them. Beneath these popular images, spelling is a human literacy ability that reflects language and nonlanguage cognitive processes. This collection of chapters presents a sample of contemporary research, across different languages, that addresses this ability. To examine spelling as an interesting scientific problem, we think several important perspectives are required. For one, spelling is the use of conventionalized writing systems that encode languages. Thus, part of the spelling problem is how an orthography (the details of a writing system) reflects the structure of a spoken language. This issue entails an examination of writing systems and the influences writing systems and their orthographies might place on spelling. This constitutes one perspective in this volume. A second perspective is to ask how children learn to spell. If the designs of writing systems and their orthographies are important in spelling, the learning-or acquisition-question is best addressed across different languages that have adapted different writing systems. In addition to the work done in the English-speaking world on spelling, research in other languages is now available to permit a broader comparative examination. We can begin

to ask about both the common principles and specific variations of spelling across different writing systems and different languages. Especially interesting from a literacy point of view is a third perspective, one that asks the extent to which spelling and reading are related. Of course, many self-professed poor spellers appear to be perfectly fine readers. This observation has tended to reinforce a separation between reading and spelling: The former is seen as a basic skill, the latter often as a special skill. One of the major themes of this collection of research on spelling is that a sharp separation of spelling and reading is misleading. Although there are distinct differences between spelling and reading, there are also important shared foundations in knowledge of word forms and in knowledge of how speech is related to writing. In collecting some of the interesting research on spelling, we have adopted each of these perspectives. Many of the chapters themselves reflect more than one perspective, and the reader will find important observations about orthographies, the relationship between spelling and reading, and issues of learning and teaching throughout the collection. To organize the collection, however, we have arranged three broad sections that reflect these three perspectives to some degree. Part I, Theoretical Foundations: Writing Systems, Psycholinguistics, and Neuropsychology, contains two chapters that deal with writing systems and orthographies. Jean-Pierre Jaffré provides a historical linguistic approach that sharpens distinctions, often blurred in the literature, among scripts, writing systems, and orthographies, while also arguing for the limitations of static linguistic approaches. Charles Perfetti develops a psycholinguistic foundation for spelling, one that, like Jaffré's, requires attention to the principles of writing systems and orthographies but further suggests a wider spoken language basis even for nonalphabetic systems. A central feature of this chapter is the argument that spelling and reading are related through shared mental representations that bond orthographic with phonological information. Complementing these chapters on linguistic and cognitive foundations of spelling, Pascal Zesiger and Marie-Pierre de Partz examine the cognitive neuropsychological foundations. The neuropsychological approach emphasizes the potential for highly differentiated processes, with presumptive functional neuroanatomy, that can contribute to spelling. The authors summarize some of the models of spelling and the research they have prompted, noting both the progress and the unanswered questions. Part II, The Acquisition of Spelling, contains six chapters reporting research on how children learn to spell. Here, the issue of language and writing systems is represented by chapters that refer to research in English, French, German, and Dutch. (Chapter 11 in Part III refers to Hebrew.) Rebecca Treiman and Marie Cassar review existing theories of spelling development and present research suggesting that, although sound is important in children's
< previous page

page_xiii
next page > Page xiii
spelling, morphological information is also important. The early use of different kinds of knowledge, they argue, reveals that stage models of spelling development are too simple. Heinz Wimmer and Karin Landerl present research on Austrian children's spelling in German, with some interesting comparisons with English. The differences between English and German spelling problems, they suggest, reflect differences in the two orthographic systems and perhaps in the instructional programs, which in Austria are typically more code-based than in English-speaking countries. Providing data in a different language, Corinne Totereau, Marie-Geneviève Thevenin, and Michel Fayol examine children's spelling of plurals in French. In this examination, they exploit a feature of French that is not present in either English or German, namely, the failure for both noun plurals and third person verb plurals to be phonetically distinguished in speech, despite being marked in spelling. Their study exposes morphological processes in spelling and suggests that these particular morphological processes are acquired in phases. French language research is continued in the chapter by Jesus Alegria and Philippe Mousty, who discuss their studies of reading disabled children, exploiting inconsistencies in how certain phonemes are spelled. From their findings, they suggest that reading disabled children can use partial cues for reading that, however, are insufficient for complete representations of words. Also reporting French language research, Linda Allal focuses on learning to spell in the classroom. This chapter is especially important in providing a clear focus on instruction within a conceptual framework. Allal distinguishes broad categories of instructional approaches, those that treat spelling as a specific school subject and those that treat spelling in an integrated literacy context. Reviewing research in both English and French, she concludes that some coordination of these two approaches, each having different potential benefits, is useful. In the final chapter of Part II, Terezinha Nunes, Peter Bryant, and Miriam Bindman present a study of the role of morphology in the spelling of English children, focusing on the -ed past tense marker. They argue that there is a developmental sequence driven by sensitivity to spoken language, with phonological awareness driving the earliest stages and grammatical awareness driving the final stage. In between, the child uses morphological patterns such as -ed as units but without grammatical awareness. Part III, The Relationship Between Spelling and Reading, contains eight chapters. Again, there is a theme of learning to spell, but chapters in this section more explicitly tie the acquisition of spelling to the acquisition of reading. Anna Bosman and Guy Van Orden present a theoretical account of why spelling is more difficult than reading, drawing on studies of Dutch children and on the dynamic systems framework for word perception (Stone & Van Orden, 1994). Their theoretical account captures the intimate connections

between orthographic and phonological forms. One of the interesting implications is instructional: Contrary to simple pattern learning ideas, reading may not be the most effective way to learn to spell, a skill that benefits from specific spelling strategies. This chapter is also important in providing a theoretical account congenial to other chapters (Perfetti, chapter 2; Berent and Frost, chapter 11). Iris Berent and Ram Frost provide a theoretical account of spelling and reading in Hebrew, which omits vowel marks in most written texts, creating multiple word candidates for a given written string of consonants. They propose a model of spelling in which both the assembly of letters from sound-letter connections and retrieval of whole words play a role; knowledge about specific word forms suppresses erroneous letters that, in other words, would be correct spellings. Jean Emile Gombert, Peter Bryant, and Nicola Warrick examine the role of analogy in spelling and reading, arguing that in both cases analogy permits the beginning learner to go beyond explicit knowledge. They review studies in both French and English in making the case for a central role for analogies, first in reading and then slightly later in spelling. Linnea Ehri presents a comprehensive discussion of reading and spelling. Reviewing research on children's spelling and reading, she argues that spelling and reading rely on nearly identical representations but with some differences in the processes. Both depend on specific word knowledge, but the information adequate for reading is not always adequate for spelling. Nick Ellis develops an account that uses Frith's influential 1985 developmental model of spelling and reading as a point of departure and reviews the longitudinal studies that might shed light on what paces developmental changes. Ellis points out that development is a matter of how orthographic and phonological representations change over time and concludes that, although broad logographic stages characterize early development, orthographic and alphabetic influences are also present from the earliest time. Laurence Rieben and Madelon Saada-Robert address the relationship between spelling and reading in learners at the beginning of instruction. Using a longitudinal classroom study of students' copying, the authors conclude that the notion of stage is contradicted by the longitudinal data. Emphasizing variability among learners and flexibility within learners, the authors suggest that development trends show phases of dominance among spelling and reading strategies rather than stages. Philip Seymour's chapter proposes a theory of orthographic and morphological development, in which spelling and reading develop around a framework that encodes abstract properties of written language. The framework changes with development, drawing on logographic and alphabetic foundations in interaction with linguistic awareness. In the final chapter of Part III, Liliane Sprenger-Charolles, Linda Siegel, and Danielle Béchennec summarize their longitudinal studies of French children, which suggest interesting

differences between spelling and reading acquisition. The earliest phase of spelling appears to rely more on sublexical phonological connections than the earliest phase of reading, for example. At the same time, however, their study observed that reading and spelling developed together, both relying on phonological processes and both contributing to the establishment of an orthographic lexicon. There are some additional observations to make about the collection of chapters. One is that the chapters are brief. The editors instructed the authors to write brief stories about their work on spelling, saving full research reports for journals. We hoped to have a slim volume that would be inviting rather than intimidating to students and researchers and that would be of some interest to instructional practice. (Although we think the volume contains some of the best work in spelling, keeping the volume thin meant that some very good work on spelling, unfortunately, is not represented.) Another point to note is that a French language collection of these chapters, tentatively titled Des Orthographes et leur acquisition, edited by Laurence Rieben, Michel Fayol, and Charles Perfetti, is being published. We hope that, in addition to illustrating how issues of spelling and reading require the perspective of languages other than English, the publication of the same chapters in two languages will increase the prospects for international cooperation as well as cross-linguistic comparisons.
Acknowledgments The editors wish to express their appreciation to their respective institutions in Pittsburgh (The Learning Research and Development Center and the Department of Psychology), Geneva (the University of Geneva), and Dijon (the University of Bourgogne) for their support in this project. For very important help in tracking and organizing the contributions during the early phases, we are grateful to Kathy Rud of the Department of Psychology of the University of Pittsburgh. To Mara Georgi, of the Learning Research and Development Center, we express our appreciation for contributions to all phases of the project, especially in editing chapter drafts, proofing final chapters, and preparing the index. So critical were her efforts on behalf of this volume, that we think of her as the fourth editor. CHARLES A. PERFETTI LAURENCE RIEBEN MICHEL FAYOL

Chapter 1 from Writing to Orthography: The Functions and Limits of the Notion of System Jean-Pierre Jaffré CNRS-HESO, Paris Written language, even today, is regarded as a poor relation in linguistics. The importance of written language in other fields of research, however, adds irony to this situation. The reasons for it are to be found in the history of linguistic ideas over the last few decades. In France, as in many other countries, the ''Golden Age'' of linguistics coincided with the reign of structuralism that, following the Saussurian model, primarily concerned itself with spoken language, relegating writing to a secondary level. Saussure's (1972) now famous axiom, "The linguistic object is not both the written and the spoken forms of words; the spoken forms alone constitute the object" (p. 45)1 is echoed by that of Bloomfield (1970): "Writing is not language, but merely a way of recording language by means of visible marks" (p. 25). Linguistics and Written Language The Saussurian tradition, in introducing a dichotomy between synchronic and diachronic linguistics, established a useful separation between spoken and written language. This helped to clarify a situation that, with traditional philology, had long been muddled. However, by placing phonological theory 1 "L'objet linguistique n'est pas défini par la combinaison du mot écrit et du mot parlé; ce dernier constitue à lui seul cet objet" (Saussure, 1972).

at the center of linguistics, the Saussurian tradition effectively excluded written language (without which this linguistic theory would, paradoxically, never have existed at all). Various claims were made in the name of this theory, including the claim that writing should ideally be phonological. This gave rise, in the 1960s, to a certain number of ideological offshoots what Harris (1986) termed "the tyranny of the alphabet" (p. 29). In some linguistic schools, however, written language continued to survive in the glossematics of Hjelmslev (1966, 1985) and Uldall (1944) and in the functionalism of Vachek (1973). Present-day research into written language owes much to the work of these precursors and to their efforts to raise written language to the same status as spoken language. For the members of the Glossematic school, written and spoken language exist alongside one another as expressions of one and the same language. Hjelmslev (1985) thus explained that both speech and written language as well as many other sign systems have a semiotic function, and he analyzed graphemes in the same way as phonemes. Uldall qualified this position, considering written and spoken language as coexistent but asymmetrical. Vachek (1973) went a step farther, underlining the complementary nature of what he termed the spoken norm and the written norm. The impact of Vachek's thinking has been such that, today, scholars of quite different tendencies claim to be his successors. Some have taken his concept of separate spoken and written norms as the basis for an autonomous view of writing (Anis, Chiss, & Puech, 1988); others take a less radical stance (Jaffré, 1993). Vachek (1987) pointed out that although the existence of a written norm may imply a certain amount of functional autonomy, writing can never be completely autonomous from speech. He even added that it is essential that there should be links between written and spoken language, for if the gap between the two norms became too wide, orthographic reform is necessary. Although this position is by no means unanimously accepted today, many linguists now see the need for a linguistics of writing, and they acknowledge that written and spoken language are two different yet equal types of expression. The precise nature of the relation between these two linguistic media remains a matter for debate, and the frequently used notion of asymmetry only goes some of the way toward answering the question. We can even find differences in the terminology used by various linguists: Vachek (1973), for example, referred to norms; others referred to systems (Robins, 1973) and still others to languages (Lyons, 1970). To refer to written and spoken norms, as Vachek (1973) did, seems to imply the existence of a single language system that sits at a higher level. Vachek did not, however, acknowledge a theoretical construction of this kind. He merely pointed out that there are structural correspondences between written and spoken language and that these correspondences become orthography when they go from speech to writing and pronunciation

page_5
next page > Page 5
when they go from writing to speech. However, in a somewhat obscure way, he also assumed that the written norm functions as a superstructure with regard to its oral counterpart. Robins, on the other hand, stated quite clearly that speech and writing both belong to the same language (1973). Catach (1988, 1995) went further, explaining the asymmetry between speech and writing by introducing the concept of a prime language, a kind of high-level language (langue supérieure) that has been modified and enriched by writing. The Mixed Nature of Writing Although this introduction explains how writing has gradually come to be accepted in linguistics, it has not given any indication of how writing functions. There are a number of studies on this subject that emphasize the mixed nature of writing. Champollion was, in this respect, something of a forerunner when, in 1822, he wrote the following in his Letter to M. Dacier. "I therefore believe, sir, that phonetic writing existed in Egypt at a very early date, and that it was at first a necessary component of ideographic writing" (pp. 41-42).2 This awareness of the coexistence of different principles within the same writing system is very modern, but it has taken some time for it to become widespread. Until quite recently, writing systems tended to be classified according to one or another principle (Gelb, 1973; Sampson, 1985). Robins (1973), who noted that all writing systems are far from being pure specimens and that mixed systems are to be found, nonetheless considered mixed systems to be the exception rather than the rule. This idea of mixed systems has, in fact, come to be accepted by linguists because of their inability to describe written language in the same way as spoken language. As long as the classification of writing systems forces each system to be in one category, there is no way to recognize the multiplicity of linguistic stuctures honored to various degrees across systems. One has to consider writing as nothing more than a historical accident, a secondary system that got out of hand, or else one must restrict the role of the phonographic principle by setting it within a broader conception of writing, one that encompasses other principles and involves other linguistic units (morphological and lexical). I prefer the second option, but, before developing this idea further, I first explain the terminology used here. Definitions and Terminology Any theoretical discussion of written language must give a definition of the object being discussed, especially because the notion of writing can cover 2 "Je pense donc, monsieur, que l'écriture phonétique exista en Egypte à une époque fort reculée; qu'elle était d'abord une partie nécessaire de l'écriture idéographique."

a multitude of different things. Here, I focus primarily on the concepts of writing and orthography. Writing. Although linguists' definitions of writing refer to language or a particular language, they may differ substantially according to the theoretical conceptions on which they are based. I do not intend to draw an exhaustive list here, but it is interesting to show the main steps in the gradation through a few examples. For historians, writing is a process that is entirely subservient to language, without it ever being clear whether language refers to spoken language or to something more abstract. For Cohen (1958), writing is "a visual and durable representation of language, which enables it to be transmitted and preserved" (p. 1),3 whereas for Février (1959/1984), it is "a device used to immobilize and to fix articulated language, which is inherently volatile" (p. 9).4 This concept of writing, defined in very general terms, contrasts with that of Vachek (1939), who distinguished between writing and written language. Whereas writing is defined as "the inventory of graphical means which can be used in putting down written utterances" (p. 104), written language is "a system of graphical means which are accepted as a norm by the members of a given linguistic community" (p. 104). Here, the idea of writing in a general sense is distinguished from its use within a particular society. Another step forward was made when the notions of internal structure and function were brought in, and the object of study was referred to, in the plural, as scripts. This latter point is of considerable importance. Catach (1988) pointed out that "Scripts are sets of discrete, articulated and arbitrary signs, which enable any constructed message to be transmitted without necessarily using natural means" (p. 243).5 Orthography. What is the difference between writing and orthography? Vachek (1939/1989) used the term orthography to refer to the necessary relations between the spoken norm and the written norm. However, this definition is exceptional: Elsewhere, the term orthography, or spelling, is used to refer to a particular state of writing, without it always being clear what this state is. Cohen (1958) used both terms, without giving a clear definition of either. He wrote at one point of the "orthographies of alphabetical writing" (p. 234), suggesting that an orthography is an actualized form of writing. 3 "une représentation visuelle et durable de la langue, qui le rend transportable et conservable." 4 "un procédé dont on se sert pour immobiliser, pour fixer le langage articulé, fugitif dans son essence même." 5 "Les écritures sont des ensembles de signes discrets, articulés et arbitraires, permettant de communiquer n'importe quel message construit sans nécessairement passer par la voie naturelle."

However, further on, he wrote of Arabic writing and Arabic orthography as though they were the same thing. It is interesting to compare studies of the history of writing (Cohen, 1958; Février, 1959/1984; Gaur, 1984) with those of the history of orthography and, particularly, of French orthography (Baddeley, 1993; Catach, 1968; Pasques, 1992). One may wonder why hieroglyphs from the time of the Pharaohs (around 1500 BC) should be referred to as writing, whereas written forms of the French 17th century are labeled as spellings. Is this difference in terminology due to a difference in the time period? Writing, when it is not a theoretical concept, seems to refer to the means of expression of cultures from a distant past, whereas orthography refers to more contemporary practices. A comparison of societies with a written tradition, however, suggests the historical timeline is relative. In Mesopotamia, as in Egypt, writing lasted for at least 3,000 years, whereas the foundations of socalled French orthography were laid no more than 1,000 years ago, which makes it a relatively new construction. This brief overview shows that dealing with writing and its relationship with orthography first requires a statement that clearly explains what certain terms and concepts are meant to cover. The best study from this point of view is that of Coulmas (1989), who distinguished among writing systems, scripts, and orthographies and used each concept to help define the previous one. Thus, when Coulmas talked about a writing system, he referred to the linguistic units that are represented (word writing, syllable writing, phoneme writing, etc.), whereas a script refers to an assimilation of a given writing system with the language using it (Chinese, Greek script, etc.). Finally, orthography refers to a standardization that is characteristic of a specific language (German, French, etc.). The main advantage of this terminology is that it allows us to describe writing as a general semiotic object as well as a linguistic object whenever it interacts with a particular language. From now on, our analysis is organized along the lines of this tripartite conception, going from the general to the particular. Accordingly, as a conclusion to this first section, I propose a set of definitions that should help avoid certain ambiguities and should lead to a better understanding of what writing and orthography have in common and what is proper to each term (see Table 1.1). The three concepts, taken as a whole, make up what I term writing, or written notation. From Writing to Scripts For the linguist, writing is defined primarily by its relation to language first, in its spoken form, and then, gradually, as a broader concept, whether in the sense of a social entity (as in Vachek's, 1939, linguistic community) or as

TABLE 1.1 Writing, Script, and Orthography: Levels and Definitions Concepts Levels Definitions Writing Principles Potential system of notation for basic linguistic structures (phonemes, syllables, morphemes, words) Script Principles Actual system of notation for basic linguistic in structures operation by means of visible marks Usage Orthography Normalization of an actual system of notation Spelling for basic linguistic structures by means of visible marks a more abstract notion such as Catach's (1988) prime language. Only glottographic traces, unlike semasiographic traces, can be defined as writing. The former are visible representations of linguistic utterances, whereas the latter represent ideas that may be oralized, but cannot be translated word for word (Sampson, 1985). Writing, therefore, is defined by its ability to represent linguistic units (phonemes, syllables, words, etc.), and typologies of writing (or writing systems) have been made along these lines. Hence, we have logographic, syllabic, or alphabetic writing (Gelb, 1973; Pulgram, 1976; Sampson, 1985), or even morphemic or phonemic writing (Hill, 1967). A script is defined by the special relationship that it has either with the basic spoken units or with the meaningful elements of a language and, in particular, with its morphology. The fact that writing represents different kinds of units from language has often led to a misunderstanding of mixed systems. Thus, Scholfield (1994) defined mixed systems as "more than one writing system used at once" (p. 56) and gave Japanese, which uses both kanji (the logographic system) and kana (the syllabic system), as examples. However, DeFrancis (1989) distinguished two ways of transmitting meaning using a single writing system: by symbols that represent sounds (and, therefore, function as oral substitutes) and by symbols that supply information of a nonphonemic type. He insisted, rightly, that all scripts result from the combination of these two tendencies, in varying proportions, and he called this the "Duality Principle." Thus, the poorer a system is, from a phonemic point of view, the more it must compensate on a nonphonemic level. However, DeFrancis retained a distinction between pure and mixed systems and, therefore, remains very strongly attached to the correspondence of writing with spoken language. Catach (1988) made better use of the concept of mixed systems by introducing the idea of "Protean" scripts.6 She set out a range of modes of coexistence between nonmeaningful and meaningful units, ranging from virtual transparency (e.g., Finnish) to virtual bilingualism (e.g., Chinese), 6 Proteus was a mythological god who often changed his appearance. So, the word Protean points out that writing can take different forms.

with a number of intermediate solutions in between, according to the role of the respective linguistic units. The phonographic relation may be relatively regular as in Italian and German, or irregular, leaving more scope to morphology as in French and English. Thus, to return to the theoretical model I develop here, writing, at the most abstract, conceptual level, combines two principles: phonographic and semiographic. The phonographic principle corresponds, more or less, to Vachek's (1973) orthography and is manifested by correspondences between meaningless units of spoken language (phonemes or syllables) and meaningless units of written language (phonograms or syllabograms). The semiographic principle encompasses the units and their functions in the linguistic elements of written language. These units are determined by the morphological structure of the languages in question, whether there are links with the spoken language (morphonograms) or not (morphograms), and by the way in which the written words are assembled. The Phonographic Principle in Writing The phonographic notation is inseparable from the notion of writing, at least insofar as we are analyzing it from a linguistic viewpoint. One could discuss how it came into existence and imagine a genetic hypothesis of phonographic units appearing first randomly, then gradually becoming more systematic. On this point, most scholars agree that phonographic notation appeared at an early stage but that it remained of secondary importance, as though it had appeared by accident (Bottéro, 1987; Coulmas, 1989; Gelb, 1973). This line of thought often underpins an evolutionary hypothesis, which sees the history of writing as a progression towards increasingly phonographic scripts whose crowning glory was the Greek alphabet (Havelock, 1981). This evolutionary hypothesis has been widely, and rightly, criticized. However, it does not follow from such criticism that scripts cannot be compared or treated as interrelated parts of one and the same phenomenon. In recent years, the analysis of scripts as completely closed systems has gained increasing acceptance, no doubt in reaction to the evolutionary hypothesis. Michalowski (1994) claimed that, around the end of the 4th millenium BC, Sumerian writing was already a system whose main principles were to change very little from then on. A similar remark is made by Catach (1992) who said, while commenting on the Palette of Narmer (4000 BC), that "the whole system is already there" (p. 5). If the system is already there, it is in a very particular form and its phonographic dimension functions in a very specific way. Our skepticism on this point is not due to the confusion to which this particular form of writing can give rise (and which, in the case of Egyptian hieroglyphs, had long misled its decryptors) but rather to the apparently incidental nature

of the phonographic notation represented here. The same thing applies to the Mesopotamian scripts that, according to Michalowski (1994), comprise phonographic elements in such a way that it is impossible to see them as a later development. We feel that it is unwise to make sweeping statements of this kind; otherwise, phonographic tyranny could well replace the alphabetical tyranny formerly denounced by Harris (1986). If the system is already there, does this mean that writing is immanent and unchanging? As Michalowski (1994) pointed out, the functions that writing are supposed to fulfill and, accordingly, the relation to language that these functions imply, change over time. These functions can have quite different relations with speech. For example, a system that notated language in an approximate way was quite adequate for the economic needs of the Bronze Age Greeks in Crete. However, the private and literary needs of Greeks during the Classical Age required a much more precise notation of spoken language, particularly of vowels (Powell, 1991). The Phonographic Enigma. The quest for a phonographic notation that adheres rigidly to the spoken language is illusory. If writing, from the outset, had recourse to phonographic notations (even indirect ones such as rebuses), it was because writing needed a practical means of recording language, not sounds. The aim of writing is not simply to record phonemes, and to do so is only useful insofar as it can transmit messages, regardless of how accessible the forms it produces may be. What it comes down to is finding a conventional means of representing linguistic content. That is why any phonographic notation is, above all, useful as a recurrent infrastructure, and it must therefore be relatively economical. The notion of economy, in linguistics, may have a number of meanings. I use it here mainly in a structural sense: as few units as possible.7 These units form a bridge with the spoken language, allowing a kind of cloning process to take place, as recent studies on reading acquisition have shown.8 Mastering this process is, however, only one of the conditions necessary for learning to read and write, which also comprises an infrastructural dimension in which phonograms, or syllabograms, merge into a bigger picture to make up larger linguistic units with a lexical or grammatical function. The phonographic dimension is, therefore, present in all scripts. However, scripts cannot be analyzed on this basis alone. As we explained earlier, 7 Another sense of economy is "linguistic economy" that concerns the distribution of the constituent elements of a system. Structural economy, the sense used here, is not necessarily a reliable indicator of the degree of efficiency of linguistic economy because the functionality of a script cannot be measured by the number of nonsignificant units that make up its structural base. 8 Studies on learning to read are numerous. For a representative set, see Rieben and Perfetti, 1991.

with the principle of mixed systems, the units that belong to this dimension are conditioned by linguistic units at a higher level. DeFrancis (1989) saw this as sufficient grounds to distinguish between what he called pure systems on the one hand and meaning-plus-sound systems on the other. He included Finnish (an alphabetical script) and the Japanese kana (a syllabic script) among the pure systems, whereas in the second category, he put English (an alphabetical script) and Chinese (a syllabic script). A similar idea is expressed in the "Four Solutions" of Catach (1988). To describe the accessibility or the degree of transparency of the phonographic option, language psychologists often use the terms shallow orthography and deep orthography. According to the definitions used here, orthography refers to script because the difference between the shallow and the deep hinges on the transparency of the phonographic units. The closer the number of phonograms is to the number of phonemes, the closer the script is to being completely transparent. Conversely, when there is a considerable difference between the number of phonemes and the number of phonograms (the latter always being greater), the phonographic link becomes complex, and it is difficult to access the script by a phonographic approach alone. This is the case in French, which has about 30 phonemes and more than 130 phonograms (Catach, 1980). This is also the case in Chinese, in which the syllabic notation is far from reliable. However, studies on these points are often contradictory: DeFrancis (1984), for example, analyzed 895 phonetic keys in Chinese and concluded that 66% of the cases give a reliable indication of pronunciation. Sampson (1985), however, explained that these keys, whether phonetic or semantic, only provide clues, which are then subject to interpretation, and he concluded that in Chinese, pronunciation is very difficult to predict. The Semiographic Principle in Writing The semiographic principle, when applied to writing, is probably even more heterogeneous than the phonographic principle. Most typologies of writing systems, whether old or new, generally use the term logographic (Sampson, 1985), which itself replaced such inaccurate terms as pictographic and ideographic (DeFrancis, 1984). However, the term logographic, or writing in words, is inadequate to describe the linguistic complexity of written forms that very often contain several meaningful units, or morphemes. Mediation of Meaning. Each script is conditioned by its raison d'être: the mediation of linguistic meaning. In performing this semiologic achievement, the script puts on stage linguistic signs that, de facto, acquire some phonographic autonomy. This graphic production of language depends not only on some internal factors such as the morphologic structure but also on external factors. Thus, the needs of Aegean society were not the same

as those of Sumerian society, and both are equally remote from the needs of our present-day society. In Minoan Crete, the tables inscribed with the Linear B script had an economic function and were adapted to a relatively rudimentary type of written mediation: that of making lists (Godart, 1990). On the other hand, Sumerian culture, which valued literary expression at a very early date, had to invent more complex linguistic forms in order to transcribe mythological works such as the Epic of Gilgamesh (Bottéro, 1994). The requirements of even the most ancient scripts go beyond the simple notation of concepts, giving rise to a more flexible notation that eventually established itself as a written norm. These developments presuppose an analysis of the source language and a sense of linguistic community by the speakers of the language. However, the result is not just a simple copy of the spoken language but a form of linguistic mediation created for the needs of a society with particular cultural demands in accordance with a general semiology of writing. The Semiographic Principle and Spacing. Leaving spaces between words is so much a part of our everyday written practice that it is hard to imagine that it could ever have been otherwise. In fact, these spaces can be seen as the negative trace of the semiographic dimension inherent to writing. A quick review of the different marks used at different periods to separate words shows, however, that the use of spaces is only one of the many semiographic means available. Whereas spacing is a kind of negative mark, other types of marks can be termed positive. These include the median point that the Romans used to place midway between the upper and lower parts of letters (Wingo, 1972), or the wedge widely used in Old Persian (Doblhofer, 1959). We can also include here the subdivisions used in Sumerian tablets to segregate words or sentences in lines or in boxes (André-Leickman, 1982). In the earliest Semitic scripts, a short stroke was used for the same purpose (Naveh, 1973). These different examples are not an exhaustive list, but they confirm that a marking process is inherent to writing, although it has not always been used in a systematic way. The meaningful segments isolated in this way range from linguistic elements to larger units made up of several morphemes. The division of units can be made in even more elaborate ways, according to the internal functioning of the script in question. One of the most recent examples is found in Japanese, in which the general tendency is to intersperse the kana and kanji scripts according to function, with kanji used for lexical functions and kana used for grammatical functions. The identification of meaningful units is helped along by objective associations whose functional status is reflected, at least in part, in the script itself (Coulmas, 1989). In ancient scripts, this role is more usually played by determiners. In Mesopotamian cuneiform, the polyvalence of written signs led to the ap-
< previous page

next page >
< previous page
page_13
next page > Page 13
pearance of determiners that were placed at the beginning or at the end of words. Determiners were not pronounced but indicated the category to which the concept belonged (e.g., a god, a man, a woman, a bird, and so on) (André-Leickman, 1982). A similar device was used in Egyptian hieroglyphs, in which certain signs were used alongside others to indicate the category (Ziegler, 1982). These determiners acted, although in an indirect and irregular way, as semiographic clues. Thus, the semiographic principle can take on different forms from one script to another, according to the linguistic structures of the language, and, more generally, to the gradual development of writing practices. There is little point in speculating on whether one type of device is better than another because all scripts must be considered in their own right and in their own context. The study of morphogenesis does not, however, reveal a regular and progressive emergence of the practice of spacing. This was emphasized by Naveh (1973) on the subject of Semitic scripts. He observed that, by around the 7th century BC, each script had developed its own method. Thus, the more conservative Hebrew script tended to separate words by using dots, whereas Aramaic was more inclined to introduce word spaces, and Phoenician preferred the system of scriptio continua, which it passed on to the Greeks. Morphology and The Dynamics of The Semiographic Principle. In modern scripts, division into words is the most obvious mark of the semiographic function. The written word seems to be, from this point of view, the most widespread notion among the linguistic community and, at the same time, the hardest to define in linguistic terms (Gruaz, 1987). However, this is due to the fact that semiography, as we understand it here, includes morphological features that are subject to quite different laws. Linguistics has long classified languages according to a number of predominant typological principles. Thus, the morphological typology introduced in the 19th century by the Schlegel brothers and perfected by von Humboldt has given rise to a classification of languages: analytic/isolating, agglutinative, inflectional, and polysynthetic. This typology has been criticized for various reasons, mainly because it categorizes languages on morphological grounds alone and that these categories are mutually exclusive (i.e., a language must be analytic or agglutinative or inflectional). More recent attempts by linguists to define language typologies take into account more diverse factors, including linguistic functions (Croft, 1990). Generally speaking, they consider languages as a combination of structures and functions that can be described in terms of predominant features. From a morphological point of view, languages may therefore be predominantly analytic, agglutinative, and so on (Hagège, 1985). A linguistic typology based on a morphology is useful if we want to examine the relation between

languages and scripts. To give two examples: First, a predominantly analytic language such as Chinese favors isolated graphic representations. This explains why Chinese writing has sometimes been described as morphosyllabic (DeFrancis, 1984). Second, an agglutinative language such as Turkish increases the interdependence of meaningful units, and we may, therefore, expect the semiographic principle to bear on more complex meaningful units (Çapan, 1989). Words, sequences of letters between two spaces, are meaningful units with variable geometry, structured on a morphological basis. If we want to describe these variations by using existent linguistic typologies, we can say that there are two semiographic options, which we term the morphographic option and the logographic option (Jaffré, 1994). The morphographic option is found wherever each graphic unit corresponds to one, and one only, linguistic sign. This major influence of the analytic type, which is predominant in Chinese, is also found in most scripts throughout the world, most notably in cases where words are morphologically invariable. This is the case for words such as ''pour,'' "sur," "dans," and so on in French; "at," "from," "for," and so forth in English; "donde," "para," "con," and so on in Spanish. Inflectional and agglutinative languages, on the other hand, favor an option that tends to assemble morphemes within a single written sequence. Thus, in Turkish, written words can be quite long, containing several meaningful units. To simplify, we can say that these languages function by placing suffixal elements to the right of a root, in a predictable order, even if these elements are not realized (Kornfilt, 1987). In written Japanese, as in Chinese, morphemes are juxtaposed, but the intermixing of kanji and kana makes for easier identification of the logographic blocks produced (Shibatani, 1987). The inflectional type of language generates a variant of the logographic option that seems to be more complex than the types described previously because it modifies the form of the meaningful units. Although it is based, as is the agglutinative type, on the effective association of a root and affixes, it differs from the relatively regular distribution found in Japanese and Turkish. We find frequent and systematic examples of this in Semitic scripts (e.g., Hebrew and Arabic) where the lexical part of words (the root) and the grammatical part (the inflection) are amalgamated (Berman, 1985). We can also find this in French, in the conjugated forms of irregular verbs such as "faire," "vouloir," "venir," and so on, where the boundary between the root and the inflection is so unclear that linguists, in order to account for it, have had to create the notion of thematic stem (e.g., for the "eu" in "je veux"). Thus, we can see that the ways in which scripts work are relatively simple as long as we are concerned only with principles. However, when these principles are set into operation, various factors are brought into play that complicate the situation considerably. Although it is still possible and necessary to adopt a systematic approach to writing, we are well aware that

scripts are never fully predictable, mathematical means of notation. They bear the marks of their eventful development, full of accidents and exceptions. In addition to this, we must bear in mind that scripts are only very rarely original creations. Michalowski (1994) listed only four societies (the "Gang of Four") that created their own scripts: Sumerian, Egyptian, Chinese, and Central American. In most cases, scripts were borrowed from an influential neighboring society. This borrowing favored the importation of foreign linguistic features. However, the history of writing shows that creations, borrowings, adaptations, and the apparently anarchic conflicts that resulted from them, did not give rise to chaotic artifacts. Linguistic analyses show, on the contrary, that there is a kind of structural balance behind which we can see the dual principles of semiographics and phonographics at work. This brings us back to a typological analysis that tends to show that there is not an infinite number of possibilities but that everything oscillates between syllables and phonemes on the one hand and morphemes and lexemes on the other. In spite of the differences between them, it is as though scripts were the reflection of an archetypal human activity. From Scripts to Orthography Writing is not an exact science, but only the visible record of human knowledge. It reflects, at least to a certain extent, the human capacity to think in an abstract way about one's own language (Veltman, 1992). Accordingly, we may try, as we have just done, to grasp the recurrent, systematic part of writing as represented in the linguistic mediation of writing. However, such as attempt can be only partly successful. There is always a part of scripts that cannot be contained within the boundaries of the system. Because they are also cultural, institutional, and social objects, scripts can become conditioned by nonlinguistic factors. Convention is reinforced by usage. Of course, the linguistic norm is not the same as the orthographical norm, but it is, so to speak, a prerequisite for it and can help it become established. For this reason, the orthographical norm, a kind of supernorm, has all the more chance of becoming implanted if the script it corresponds to is old and bears the weight of history. This point, no doubt, deserves a far more detailed analysis than we can give here. We need to enlist the help of palaeography and epigraphy to give us more information about the practices of scribes in ancient societies. However limited our information may be on this subject, we can assume that scribal practices were particularly ritualized (Kramer, 1986). Scribes, as "professional writers," had the power to introduce certain innovations; however, the history of writing shows only too well that the greatest innovations took place when scripts were being borrowed, that is, at their earliest, formative stages (Naveh, 1987).

Naveh (1973) and Saenger (1982) made quite similar observations concerning the segmentation of writing at different times and in different societies. They explained that as far as writing is concerned, the most conservative groups are those whose mother tongue is mediated by the script in question. Conversely, when an external user uses the same script, and the language is foreign to him, he does not hesitate to take liberties with it and to introduce changes. Accordingly, Assyrian scribes seem to have been the first to introduce spacing in Aramaic script, which they used for international purposes, at around 1000 BC (Naveh, 1973). Similarly, Irish monks were apparently the first to reintroduce spacing in works written in Latin around the 7th century AD (Saenger, 1982). The establishment of an orthographical supernorm also depends on the requirements that writing is to fulfill. A supernorm has more chance of being established when writing has a political or religious function, as was the case with Egyptian hieroglyphs (Davies, 1987) or with Hebrew in the kingdoms of Judah and Israel (Naveh, 1987). This supernorm allows power to be established and preserved. Conversely, when writing serves an economic purpose, it is more likely to be functional, and the more widespread its commercial use, the more flexible it is likely to be. This is the case with Phoenician, which was used throughout the Mediterranean from 1000 BC onward (Gras, Rouillard, & Teixidor, 1989). These situations are obviously quite different from those of modern societies: Our orthographies are the result of an unprecedented expansion in the use of writing. We must not forget that in ancient societies the use of writing was restricted to a very small number of people: Even in Ancient Greece, it is likely that not more than 10% of men were able to write (Harris, 1989). However, having said that, we may say that all societies with a written tradition manage, each in its own way, to produce an orthographical supernorm that makes writing an instrument of power and of social preference. When faced with orthographies, linguistics can be concerned only with their systematic features (and those of their scripts). The remainder is a topic for sociolinguistics, provided that they agree on what is meant by orthography. My emphasis on the possible confusions that can arise between writing and orthography has been a reponse to a history of variant uses of these terms, with accompanying misunderstandings. Consider that many authors have referred to orthography when discussing French (Baddeley, 1993; Beaulieux, 1967; Catach, 1968; Pasques, 1992), English (Scragg, 1974), Catalan (Segarra, 1985), and Spanish (Esteve Serrano, 1982) writing between the 13th and 17th centuries. However, because an orthographic norm was not truly established until the 19th century (Guion, 1973), the use of the term orthography in reference to this earlier writing is misleading. Although these studies do describe the foundations of what was to become the orthographical norm and how it was formed, they show that writing is a human science, patterned

by conflicts, disputes, and even "civil wars" between the partisans of a predominantly phonographic option and the partisans of a predominantly semiographic option. The problems that they study are not, after all, very different from those raised by scholars who study ancient scripts such as Greek (Powell, 1991) or Latin (Desbordes, 1990). Conclusions Linguistics describes facts and constructs systems that can give rise to working hypotheses in other fields, particularly that of language acquisition. It is, moreover, increasingly likely that present studies on acquisition will lead us to modify some of our linguistic hypotheses. Although the linguist's analyses are necessarily different from those of the psychologist, the theoretical options each chooses can help both of them to see eye to eye on certain matters. The linguistics of writing has tended to favor the methods of structural linguistics (and in particular the concept of synchrony) in order to be recognized as a discipline in its own right. Because of this, there is now an unfortunate division between the theories of writing and the studies of the history of writing, whether scripts or orthographies. It is now time to build another kind of linguistics, and this chapter has shown how this may be possible (see Jaffré, 1995). All orthographies and all scripts are part of a bigger picture by which they are conditioned and which can help us to gain a better understanding of how they function. If we want to construct this bigger picture, we must first create a general theory of writing that can encompass all research carried out until now on writing systems, old and new. We must also, however, consider each script in its own right as a unique merger of semiological processes with a particular language. We must also bear in mind that languages themselves have general characteristics that can be described by linguistic typologies. Today, the linguistics of writing is at a turning point, for two reasons. First, its theoretical foundations are not quite solid enough, as the often difficult debate over the relations between spoken and written language shows only too well. Second, too few studies have as yet been carried out in this field, and those that have are very divergent, if at all necessary. It would be useful, for example, to update existing works on general models of writing systems, such as that of Gelb (1973), in order to construct new typologies that are more representative of the complex and mixed nature of scripts. We must also carry out more detailed studies on contemporary scripts, with a different epistemological approach from the works on orthographies and their formation. We also need a wider range of studies, so that large-scale comparisons can be made. The linguistics of writing needs, above all, more studies on scripts and orthographies such as Arabic, Hebrew,

Japanese, Chinese, and so on, which differ from the Western logic of the Greek alphabet and its successors. The development of archaeology is, finally, giving rise to a promising increase in epigraphic and palaeographic data. However, in spite of the importance of the findings from Mesopotamia, Egypt, Crete, the Near East, and Central America, they have as yet only brought fragmentary theoretical contributions to the linguistics of writing. These findings could help to modify considerably the all-too-static linguistic point of view. After a long period dominated by structure and synchrony, the notion of the subject is now invading the whole of linguistics in very diverse forms (historical, sociological, psychological). That is why it is not only useful but also indispensable to carry on the dialogue with language psychologists and acquisition specialists. References André-Leickman, B. (1982).

Chapter 2 The Psycholinguistics of Spelling and Reading Charles A. Perfetti University of Pittsburgh One would expect that psycholinguistics, as the study of the psychological processing of linguistic structures, is a natural home for the study of spelling. Instead, spelling has been rather neglected within mainstream psycholinguistics. The surge of research in spelling since the 1980s, to be sure, was important in correcting this neglect, even if this research was only implicitly psycholinguistic (Ehri, 1980; Frith, 1985; Henderson, 1981). Moreover, Treiman's (1993) work on spelling development shows an explicitly psycholinguistic approach: It links the acquisition of spelling to linguistic structures by specific hypotheses about linguistic units. Nevertheless, it is fair to say that there has been a relative neglect of the psycholinguistic components of spelling. One finds little coverage of the topic in textbooks on psycholinguistics. More telling is the Handbook of Psycholinguistics (Gernsbacher, 1994), which covers the basic topics of the field in 34 chapters, none of which include spelling. Indeed, the reader searches in vain for an entry in the index under spelling. The reasons for this relative neglect are manifold but include at least the scientific privilege, inherited from linguistics, given to spoken language. (Ironically, however, written language has actually dominated the empirical studies of adult psycholinguistics.) Spelling may be seen less as a scientific problem of language use than as a literacy convention or a school subject. A second reason may be that the deceptive simplicity of spelling has masked its intriguing problems, making it seem less challenging than the higher

mental processes that have preoccupied the cognitive sciences. In any case, neglect is gradually being remedied by research that addresses the processes and acquisition of spelling in relation to linguistic structures (Berent & Frost, chap. 11; Bosman & Van Orden, chap. 10; Totereau, Thevenin, & Fayol, chap. 6; Treiman, 1993; Treiman & Cassar, chap. 4). The aim of this chapter is to further contribute to the psycholinguistic study of spelling by delineating some of the relevant linguistic structures involved in spelling and by showing how psycholinguistic processes involving these structures are central to both spelling and reading. These processes and structures connect spelling with reading in a highly interdependent way. In making this case, an essential first step is to demonstrate the importance of linguistic structures that are the foundation of spelling: those that are manifest in writing systems and orthographies. Writing Systems and Languages Spelling is the encoding of linguistic forms into written forms. The linguistic units phonological strings, morphemes, and words are provided by the spoken language. The writing units are provided by the writing system and its inventory of graphic devices. Figure 2.1 illustrates the general form of the relationship between languages and writing systems. The linkages between the units of the two systems define the essential meaning of reading and writing. Both require that graphic units be connected to linguistic units. Unlike the linguistic system, which is assumed to be systematic, multilayered, and abstract, writing is often treated as unsystematic, strictly linear, and highly conventional. Spellings are often said to be arbitrary or conventionalized. The idea of convention a social contract enforced by appeal to authority does capture an important part of formal spelling. More important from a psycholinguistic perspective, however, is the fact that spelling also reflects the general principles of a writing system the writing system design and the specific orthography that embodies the general design plus its distinctive orthographic features. In Fig. 2.1, there is a distinction between the writing system and the orthography that is often ignored in psychological treatments of reading and spelling. Generally speaking, the writing system dictates the level at which general linguistic constraints are imposed on writing, whereas the orthography dictates the specific details of these constraints (see Jaffré, chap. 1, for a further discussion of these distinctions). Accordingly, writing systems can be said to be logographic, syllabic, and alphabetic, depending on the smallest linguistic unit encoded in the basic writing unit. Orthographies within writing systems show minor but significant variation concerning the rules that relate graphic units to linguistic units. Thus, written

Fig. 2.1. The general relationship among writing systems, orthographies, and languages. Languages provide multilevel units in phonology (phonemes, syllables, onsets, rimes not represented and morphology). Writing system principles select one or more levels of language for encoding into elementary writing units. Orthography is the system of constraints on the writing units, including their mapping to language units. Chinese (logographic or morphophonological), Japanese kana (syllabic), and Italian (alphabetic) belong to different writing systems. However, written English, Italian, and French (all alphabetic systems) can be said to have different orthographies.1 The study of spelling (and reading as well) has been dominated by studies of one kind of writing system, the alphabetic, and one orthography, English. The effect of this one-orthography research has been to give a distinctive character to conclusions about spelling. For example, one of the most influ1 Further distinctions are sometimes confused. Thus, alphabetic systems are not the same as alphabets: Russian, written in the Cyrillic alphabet, and French and English, written in the Roman alphabet, are equally alphabetic, and the differences in orthographies are no greater, in principle, across than within alphabets. Finally, the actual visual form of the written units, as opposed to the rules that map them to language units, is a matter of script. Thus one can refer to the CyrillicRoman contrast as a difference in script as well as the contrast between Hebrew and Arabic, which are both consonantbased "incomplete" alphabetic systems. Korean is alphabetic, but its arrangement of graphic units (letters) into uniform nonlinear spaces is a variation in script.

ential accounts of spelling is Frith's (1980, 1985) dual-route model. As with dual-route models for reading (Besner, 1987; Coltheart, 1978; Paap, Noel, & Johansen, 1992), such models seem necessary because of the unreliability of English orthography. These models assume that there are two different mechanisms for spelling words and for reading them, one that makes reference to the phoneme constituents of the word and one that does not. In reading English, the phonemic route works fine for words such as safe, but it fails for cafe. Thus, there must be a mechanism for looking up words directly and bypassing the phonology that would otherwise produce the wrong word or no word at all. In spelling, the route is reversed, from phonology to orthography. Applying the phonological (or merely phonemic) route to /kefa */ may lead to a spelling something like kufay. Even spelling /seyf/, however, could be in jeopardy along the phonemic route, producing, perhaps, saif as well as safe. The two-route approach solves this problem by allowing words (in skilled spelling) to be spelled by a mechanism that looks up lexical spellings directly, with no reference to phonemes. Or, more faithful to the modern dual-route concept, a conversion of phonemes to possible letters goes on in parallel to the lexical look up, with the two sources of information competing or converging to various degrees. A parallel argument is made for reading. Although both lexical and grapheme phoneme routes may be used in word reading, the lexical route is more reliable and will ''win'' most of the time, relegating the phonemic route to backup duty for low-frequency regular words. Whatever the scientific status of these dual-mechanism models, the point here is merely how much their development has been dependent upon a particular orthography notorious for its "irregularity." In the case of spelling, there is an important additional observation that reinforces the impression that a lexical look up is necessary. Even if the spelling is generated from phoneme grapheme conversion, the candidate spelling must be compared with the speller's representation of the written word. This verification process, usually implicit, becomes explicit and visible when a speller writes down a candidate spelling to see whether it "looks right." This verification process is likely to be quite general, perhaps universal, across orthographies. By contrast, the initial process of generating spellings on the basis of phonology may be influenced by linguistic constraints to different degrees across different orthographies. This is because orthographies differ exactly in the degree to which they directly represent the phoneme strings of the language they encode. In particular, orthographies vary in the degree to which they encode the surface phonology of the language relative to the morphology. Those orthographies that reflect relatively faithfully the surface phonology of the language (i.e., its linear string of phonemes) are referred to as shallow or transparent; those that reflect more the morphology of the language (at the

expense of the phonology) are considered deep orthographies (Frost, Katz, & Bentin, 1987). English tends toward the deep end of the continuum. Its spellings are often unfaithful to surface phonology while reflecting the deeper morphology and morphophonology. At least, that is the common assumption. In fact, there is more systematic phonology in English spelling than is commonly assumed especially when positional and letter context constraints are considered; however, it is still a relatively deep orthography. Orthographies Reflect Linguistic Structure Within the family of alphabetic writing systems, Italian provides an interesting contrast to English. It is a shallow orthography, one in which the spelling of words mirrors their pronunciation in a more reliable fashion. The reliable mapping from orthography to phonology makes Italian a transparent, shallow system for reading, and its relatively reliable mapping from phonology to orthography makes it a transparent, shallow system for spelling. This symmetrical transparency contrasts with orthographies that show a significant asymmetry between the spelling and reading transparency. For example, the orthography phonology (reading) mapping can be more reliable than the mapping for phonology to orthography (spelling). This is the case for French, for example, with very interesting consequences for spelling (see Totereau, Thevenin, & Fayol, chap. 6, this volume). To appreciate the extent to which the orthography phonology mapping functions can be made quite reliable, consider the Italian -ci- spelling, as in ciao. To the reader of Italian, the -ci- pattern signals a reliable mapping rule: -ci- maps to /c/ in all environments. So ciao is chow /cau/ and bocci is /boci/. But bocca, identical except for the a, is /boka/. It doesn't matter that in bocci, the i is pronounced, whereas in ciao, it is not pronounced. (Whether the i is pronounced is also quite predictable from the grapheme environment i before a, o, and u is inserted to signal the pronunciation of the preceding c, but is not pronounced.) In both cases, the i signals that the c is /c/ and not /k/. The same signal is given by -e-. Thus, cello, liceo, and piacere all contain the c before the e (which is not pronounced in liceo /lico/, but is in cello and piacere). Both -i- and -e- contrast with -a-, -o-, and -u-, which signal a preceding /k/: cara, ancora, cucina (the last shows both sides of the rule within a single word). This much may appear to be an arbitrary, if rather convenient, conventionalization having nothing to do with linguistic structures. However, consider the fact that g behaves the same way as c. Its pronunciation depends on whether it precedes -i- or -e-, in which case its phonemic value is /j/, or whether it precedes -a-, -o-, or -u-, in which case its phonemic value is /g/. Thus: giorno, baggio, Georgio, and gellato (all /j/), but galleria, albergo, and
< previous page

pagare (all /g/). That c and g pattern together is, of course, no coincidence. The four phonemes that map onto the two letters are cousins, paradigmatically related. /k/ and /g/ are full stop consonants that share place of articulation (the velum) and contrast in voicing /k/ is unvoiced, /g/ is voiced. /c/ and /j/ are affricates (stops followed by sudden release) that share place of articulation (the hard palate) and also contrast on voicing /c/ is unvoiced, /j/ is voiced. Thus, the paradigm is one that pairs phonemes on two features place and manner of articulation but contrasts them on one feature voicing. Spelling patterns cohere around the paradigm: Loosely speaking, -i- and -e- signal the tongue to move from the velum to the hard palate, shifting the place of articulation slightly forward to where the affricate sounds are made. The other vowels define the default case, the velar consonant voiced if there is a g and unvoiced if there is a c. To summarize, this example illustrates how a transparent orthography can map abstract phonology, not merely surface (phoneme) phonology. The spelling rules for the four consonants reflect an underlying articulation-defined paradigm. They are conventions, but they are not mere conventions. Underlying the patterns of co-occurrence in the letters is a regularity in the phonological system. Nor is this pattern seen only in Italian: French and other Romance languages have orthographies that show a parallel pattern for c and g (associated with different pairs of phonemes). And English, despite its irregularities, gives the identical pattern, but imperfectly: city versus cutey; candy versus Cindy; cell versus call; gender versus gander, barge versus bargain, and so on. These examples, which reflect Latinate influences in the evolution of English, need to be kept in mind when the irregularity of English spellings is lamented. To say, in English, that "c is sometimes /k/ and sometimes /s/" is misleading as an example of irregularity. So far, the argument has been that spelling can reflect abstract phonology. This is good for reading, decoding orthography to phonology. But what about spelling itself? In the Italian case, the mapping from phonology to orthography is itself very reliable. If a spoken word contains a /c/, the speller knows that there is a c followed by an e or an i. There is no confusion as to which it is: Unlike English, the vowel that is heard is the vowel that is spelled, and there is no mistaking the phoneme values /i/ with /e/ or /ey/. What happens if no /i/ or /e/ is heard? Then the c must be followed by -i-. It alone has the duty to mark the c spelling without phonemic value (before a, o, u). Unlike English, if a /k/ is heard, it must be spelled with a c because Italian has no k. However, what happens if a /ki/ or a /ke/ is heard, as in bichierri? The skilled speller will not be tempted to spell the sound as -ci- because -ci- has to be a /c/, not a /k/. Instead the Italian speller knows that h serves that unique purpose: Inserted between the c and the -i-, it signals /k/, and, of course, with g, it is the same. The plural of albergo is alberghi. The pronunciation is maintained.

The alberghi example illustrates one final point about abstract systematic linguistic influences in spelling. It is often said that English sacrifices surface phonology to preserve morphology. For example, the root morpheme in national is spelled the same as nation even though there is a pronunciation shift in the first vowel. This serves the reader and probably the speller by drawing attention to the morphemes of the language at the cost of not representing the phonemes. (Much of the phoneme alteration is predictable, so there is little cost to phonological representations.) Notice, however, how the Italian example satisfies morphology and phonology both by a simple spelling rule. The spelling of alberghi directly signals the pronunciation, which is constant across morphological variants in this case. Other Italian examples illustrate the complementary case: pagare, an infinitive form, converts to pagiamo in the second person plural. Notice that the pronunciation of g must change because of the rule controlled by vowel spellings. The phonological shift, of course, is not imposed by the spelling but is present in the inflection system, which is part of every speaker's linguistic competence. Thus, spelling always conforms to pronunciation, which in turn reflects the morphological system. In summary, I have taken a simple example to make a point about how linguistic systems can constrain spelling. Comparisons across orthographies are tricky, however, even within those using the same alphabet, such as Italian and English. Indeed, English has a lot more linguistic constraints in its orthography than is sometimes implied (Venezky, 1970). The mere linear arrangement of letters reflects phonotactic constraints on permissible phonemic sequences. There is a difference between deep and shallow orthographies, but even deep ones within the family of alphabetic writing systems embed linguistic constraints within their conventions. The Case of Chinese From the examples so far, one might conclude that linguistic structures can be expressed in the orthographies of alphabetic writing systems (to various degrees) but draw no conclusion about a related and broader question: Do all writing systems reflect linguistic structures or only alphabetic ones? A widely shared assumption seems to be that writing systems reflect different principles of design and that linguistic units play a role in alphabetic and syllabary systems but not in all systems. In particular, Chinese, as the prime example of a meaning-based system, is sometimes assumed to reflect strictly semantic designs, with written units corresponding to concepts (ideographs) rather than to units of the language. Indeed, the origins of written Chinese, like those systems originating in the Middle East, appear to have been in pictorial elements. The long history of development of the Chinese system over more than 3,000 years, however, has yielded a system in which pictorial elements are negligible. Students of Chinese writing, although perhaps at odds over

some aspects of writing system classification (cf. DeFrancis, 1989; Gelb, 1963; Sampson, 1985; Wang, 1973), certainly agree on the preponderance of abstract form meaning relations in modern Chinese. Even more important for the question at hand, DeFrancis argued that Chinese has developed into a morphophonological system, one in which compound characters, which include the vast majority of words, contain both a meaning (morphological) and a phonetic (phonological) component. Although there is agreement that the writing system has phonological elements, some writers continue to focus almost exclusively on the semantic component, ignoring the phonological component that is critical in the system. One may speculate that the scriptal difference between Chinese and alphabetic systems has made its semantic component more visible (by contrast to alphabetic systems). That Chinese relies on phonetic elements is very important in establishing it as a system based on language rather than on ideas or concepts. Because of its morpheme component, it has a dual-level mapping, one that simultaneously and with different graphic units within the word signals meanings and pronunciations (see Perfetti & Zhang, 1995, for more on this aspect of Chinese from a reading perspective). In the scheme depicted in Fig. 2.1, written Chinese provides graphic units that are single syllables; simultaneously, they are morphemic elements that give meaning information.2 That writing systems use a mix of features rather than purely implemented principles may be a valid generalization, as Jaffré (chap. 1) argues in this volume. At the same time, the Chinese case also illustrates the remarkable degree to which all writing systems depend on language. To be more precise, although encoding the morphemes of a language into a writing system is a linguistic mapping, it is the reliance on phonological mappings in all writing systems that is truly remarkable and important in understanding the relationship between writing systems and language. Writing systems, however variably and unevenly, rest on spoken language. This fact has strong implications for how reading and spelling work as general human cognitive processes. The Spelling-Reading Relationship Revisited Spelling and reading are two sides of a coin from the perspective I take here. The first converts speech forms to written forms; the second converts written forms to speech forms. This logical symmetry, however, does not 2 An interesting question is what constitutes Chinese spelling. One reasonable answer is that there is no spelling in Chinese. There is the retrieval of graphic forms and their composition for specific words, but this is not what we usually mean by spelling. On the other hand, it is possible to suggest that Chinese spelling, as in an alphabetic writing system, is a matter of providing written word constituents, whatever the psychological source of these constituents.

demonstrate that the psycholinguistic processes are mirror images. Indeed, the consensus view has been that spelling and reading are rather different things. One of two observations is typically made on this point: (a) Spelling is more difficult than reading. Thus, reading does not require the degree of knowledge about words that spelling requires. In this view, spelling subsumes reading; (b) spelling and reading can be completely disassociated. Depending on the circumstances, spelling can be easier or more difficult than reading. On this view, there are different mechanisms involved in the two processes. The first of these corresponds to a commonsense view of the spelling reading relationship, conforming to the irrefutable fact that most people can read words that they cannot spell. The second possibility derives from dual-mechanism accounts of reading and spelling. When words can be spelled but not read, this is because reading relies on a lexical look-up procedure that fails for a particular word; however, the same word, when spoken, can be spelled on the basis of phoneme grapheme conversion mechanisms. Bryant and Bradley (1980; Bradley & Bryant, 1979) reported observations on children who showed this kind of disassociation. Similarly, Cossu and Marshall (1985) reported data on two Italian children who could read only a fraction of the words they could spell. Interestingly, these children showed this large advantage for both words and nonwords, even while performing better on words than nonwords in both reading and spelling. The representational assumptions of the restricted interactive (R-I) model of reading outlined in Perfetti (1991, 1992) provides a different view on this issue. In this model, reading and spelling are the same in the lexicon; they are different in important processing details. Their sameness comes from their mutual dependence on the quality of representations of printed word forms. This quality has two components that are enhanced with increased experience in reading and spelling: precision and redundancy. Precision is the probability that specific letter constituents are represented as part of a word in the reader's lexicon. Even experienced readers can be characterized as "missing" some letters for some words; such letters are represented as variables rather than constants. A speller, in such a case, may or may not produce a correct spelling. Redundancy is the formation of word-specific, grapheme phoneme connections. These connections are developed by the convergence of generalized grapheme phoneme correspondences and specific orthographic forms. They supplement the connection that can exist between a printed word and a spoken word form. Only one set of print phonology connections is logically necessary; two provide a safety net that assures successful and fluent word reading in a variety of situations. In fact, form-form connections (orthography-phonology) can develop at several levels (phoneme, syllable, onset, morpheme), producing, at high levels of skill, a large amount of helpful redundancy.

There is an important learning or reading acquisition assumption in the R-I model relevant for spelling: Improvements in both lexical precision and redundancy depend on phonemic knowledge (Perfetti, 1991). The reader's knowledge of speech segments draws attention to the letters of a word and encourages their full representation. The unpalatable alternative is to imagine the child developing strictly nonlinguistic (presumably visual) strategies for attending to the letters of a word and representing them. A similar idea was developed more thoroughly by Share (1995) in a theoretical review of beginning reading issues (see Share & Stanovich, 1995). Based on earlier work by Jorm and Share (1983; Share & Jorm, 1987), Share argued that phonological knowledge, specifically phonological recoding, is the fundamental mechanism for the acquisition of orthographic knowledge. In terms that combine Share's model with the R-I model, phonological recoding is a self-teaching procedure that produces more precise and more redundant lexical representations.3 These two principles of lexical quality determine the lexical expertise of the reader. More precision and more redundancy add up to more expertise. Most relevant for the present purpose is the assumption that spelling is the purest indicator of lexical quality. Lexical expertise, the claim went, is best assessed by idealized spelling performance (Perfetti, 1991, 1992). This assumption seems at odds with the disassociationist view of the spelling-reading relationship. It is more compatible however, with the commonsense spelling-subsumes-reading view. Spelling is more difficult than reading. Reading can be accomplished with incomplete word representations (i.e., representations with letters as variables). Deciding which word is accessed by a letter string is a matter of choosing one word over a cohort of similar words (neighbors), and this is possible even with imperfect word representations. In addition, decoding of letter sequences to phonemes can provide a match to the phonological representation of the target word. By contrast, spelling requires the retrieval rather than the recognition of the graphemes. Retrieval processes are errorful because (a) memory representations are low quality (imprecise in this case), or (b) interference is encountered (with competing letter sequences, in this case). On this account, errorless spelling comes with ample practice many successful word recognition events and enough successful spelling retrieval events to strengthen the precision and redundancy of the word representations. We expect, as the evidence reviewed by Bosman and Van Orden (chap. 10) suggests, that reading by itself will not dramatically improve spelling because reading does not practice the full orthographic retrieval process demanded 3 The general idea that phonological knowledge has the role of assisting in the construction of orthographic knowledge was earlier proposed by Venezky and Massaro (1979), who argued that phonics instruction might help children acquire knowledge of orthographic structure.

by spelling. Moreover, it is spelling itself that is most effective at improving the quality of the word representation. Practice at spelling should help reading more than practice at reading helps spelling. Also on this account, spelling words that cannot be read should be rare and should occur only during the stages of reading acquisition (and perhaps certain rare acquired dyslexias). Indeed, the data on the disassociation of spelling and reading are consistent with this view. In Bryant and Bradley (1980), the pattern of spelling-better-than-reading was restricted to younger and less skilled readers. Similarly, the case studies reported by Cossu and Marshall (1985) were studies of low-ability readers. Thus, what needs to be explained is not a general disassociation pattern but rather the occasional case in which a child who is very poor in reading seems to spell better than one should expect. If the claim that spelling is the indicator of high quality lexical representations is correct, then these cases are failures in which reading falls short of the potential provided by lexical representations. This conclusion appears at odds with the usual assumption that spelling in cases of disassociation occurs only by translation processes and not by access-to-word representations. However, this latter assumption does not square with the observation that nearly all children, including children who spell words they fail to read, spell real words more accurately than nonwords (Cossu, Gugliotta, & Marshall, 1995; Cossu & Marshall). Lexical representations play a part in the spelling of words for all children who have acquired some degree of literacy. So what is the source of the spelling advantage for those relatively few children who show one? It is quite possible that there is no single mechanism but rather a range of ineffective word reading strategies. When they are having trouble acquiring reading, children may develop conflicting strategies for reading words. The recognition of a regular word (i.e., one with predictable grapheme phoneme connections) may fail because the child's lexicon does not contain the word, preventing verification, or because the child is reluctant to implement imperfect knowledge of grapheme phoneme correspondences. The occasional success in spelling for the same word presented orally can be explained as follows. The spoken form does what the written form cannot do for a struggling reader: It activates a lexical representation. The spelling can be generated from this representation with the help of phoneme grapheme correspondences. Whatever the correct set of explanations, it is important to remember that what must be explained is poor reading in the presence of fair (not good) spelling; there is no need to try to explain good spelling because this is not what is observed in the disassociation. To place things in perspective, we return to the dominant pattern of reading-better-than-spelling. Children read words more successfully than they spell them, even in a transparent orthography such as Italian, in which

phonology-spelling mapping is very consistent. Indeed, Cossu et al. (1995) found that among 70 first- and second-grade children, nearly all children read words they could not spell, and no children showed the opposite pattern. In general, the assumptions of the R-I model can handle the observed patterns of spelling-reading asymmetry. The common pattern is readingbetter-than-spelling with the reversed pattern restricted to readers of low reading skill. Both patterns can be explained in terms of processes that operate on lexical representations of varying quality. Reading is usually more successful because it can tolerate noise in the representation to a greater extent than spelling can. When the representations are low quality, both reading and spelling are poor. Occasionally, ineffective reading processes fail to take advantage of the lexical representations that spelling success suggest are established. A theory of spelling, on this account, requires a distinction between spelling words and spelling phoneme sequences. Word representations, including their letter constituents, must be consulted in spelling familiar words (i.e., words whose representations include graphemes). The spelling of unfamiliar words and nonwords may occur, in principle, without consulting the lexicon. I say "in principle" because the process of spelling a pronunciation is likely to always include a search of the lexicon. Finding a lexical representation invokes a process that is both orthographic and phonological because both kinds of information are intrinsic to the word representation. Failing to find a lexical representation triggers a process that converts phonemes to graphemes, probably in consultation with lexical entries that share phonemes with the unfamiliar target word or nonword. This account appears compatible with a dual-route mechanism, and in a general way, it is, but there is a difference in the assumption of the R-I model that phonological information is bonded to orthographic representation for a skilled reader. (This assumption is closely related to Ehri's, 1978, amalgamation idea.) The interconnection, within a single word, of graphemes and phonemes, means that lexical processes themselves refer to sublexical information, including phonology. Thus, to the extent that the representation of the word is redundant containing context sensitive, grapheme sequence phoneme sequence connections phonology has an intrinsic role in any lexical process on that word, including spelling. This emphasis on phonology in the word representation is not to minimize the role of visual representations, which are important in spelling. The compelling tendency to verify spellings by writing them down for observation is probably only a surface indicator of the extent to which visual representations are used routinely in spelling. The verification process itself, however, seems to provide a link between reading and spelling. Notice that verifying a candidate spelling is the correct spelling of the target word is a process of reading. Thus, spelling itself entails reading.

Reading in Spelling, Spelling in Reading In this final section, I address a more specific implication of the R-I model's assumption that spelling and reading rely on the same mental representation, one that consists of tightly interconnected letters and phonemes. If there is a single representation and if this representation is consulted during reading and during spelling, then there is a sense in which spelling a word entails reading it and reading a word entails spelling it. The suggestion that spelling entails reading was made in the preceding section. Going from phonological form to orthographic form begins with a search of the lexicon and ends, in the case of a word, with the verification of the candidate spelling. This verification is a "reading" of the constituent letters. However, this verification involves phonology as well as spelling.4 The reading is verified when the phonological-orthographic forms that comprise the lexical representation are retrieved and compared with the candidate spelling. For a regular word such as /reyk/, the process finds a lexical entry {rake-/reyk/} (omitting for simplicity the redundant letter-phoneme connections). It reads out the orthographic constituents of the representation r-a-k-e. It then reads this form as /reyk/, completing a cycle of spelling and reading that confirms the spelling. If the spelling yields some other pronunciation, a common condition in an opaque orthography, then there will be competition (interference) during this verification process. Notice that, in verifying the spelling pattern -ake, there is no competition. Spelling an irregular word is not so different if the word is familiar. Suppose the word is /kefa */. A search of the lexicon with /kefa */ as an input yields {cafe-/kefa*/}. The spelling process reads out the orthographic constituents of the representation: c-af-e. It then reads this form as /kefa */, although now with some interference from /keyf/. However, partly because /keyf/ is not a word, /kefa */ easily wins out, and the spelling is confirmed. A more important reason it wins is that /kefa */ has just been activated in the oral spelling process, and this phonological form is primed to be connected with c-a-f-e, which, of course, activates /kefa */ on its own. Thus, there are convergent cycles of spelling and reading that go on when both regular and irregular words are spelled. I have already indicated how some spelling errors might be made. The main difficulty arises from words that are unfamiliar. The verification process fails and the speller is stuck with the form generated by phoneme-spelling mappings, analogies, or by whatever set of strategies is used in a particular case. Another error that gives a glimpse of the spelling mechanism is homophone errors. To spell /riyd/, a search of the lexicon can turn up {reed-/riyd/} or 4 Bosman and Van Orden (chap. 10) provide a detailed argument for the idea that spelling and reading reciprocally rely on a phonological process.

{read-/riyd/} or both. Because these are two distinct lexical entries, sentence context will tell the speller which word it is, and the homophone will be suppressed. (The homophone will not be successfully suppressed all the time, however, as the numerous homophone errors in writing, e.g., right instead of write, demonstrate.) In isolation, however, either entry can be accessed and the reading check will not distinguish between them. The involvement of spelling in reading is a mirror image of the process just described, one of verifying a generated candidate string against a lexical entry. This involvement is less obvious than the reading-in-spelling case, where one can appeal to an occasional explicit verification process (i.e., writing in order to read). In reading, the idea that there is a spelling verification stage is implied by complex systems resonance models of word identification (Stone & Van Orden, 1994; Van Orden & Goldinger, 1994).5 In such models, the identification of a printed word comes about by a convergence of phonological information generated by the letters of a word (a feedforward process), with the letter information generated by the phonology (a feedback process). These rapid cycles of feedforward phonology (given a letter string) and feedback spelling (given the activated phonology) constitute a resonance that singles out one word candidate from the host of word candidates that are partially activated from the initial letter string. An especially interesting implication of this model is that reading efficiency depends on spelling variability. Roughly, the more ways a phoneme sequence can be spelled in English, the longer it takes to read any word that contains that phonological sequence. This is because more possible spellings lead to more possible word candidates (actually letter sequences); with fewer possible spellings, the system settles more quickly on the target word. For example, the word shelf is more efficiently read than the word sneer. This is because the pronunciation /elf/ is always spelled elf, so there is no competition in the spelling feedback phase; by contrast, the pronunciation /ier/ associates with several spellings (eer, ear, ier, and er), creating competition in the spelling feedback phase of reading. Evidence favoring the operation of this spelling feedback mechanism rests on reading experiments with four- to six-letter words (Stone, Vanhoy, & Van Orden, 1997). In summary, the suggestion that spelling and reading processes make reference to a single lexical representation that contains interconnected orthographically specified and phonemically specific constituents now has some evidence as well as some intuitive appeal. Spelling processes seem to use reading in a verification stage; reading processes seem to use spelling 5 Earlier word reading models also contain the idea of verification. For example, the activation-verification model of Paap, Newsome, McDonald, and Schvaneveldt (1982) appealed to a verification stage in which a set of word candidates activated during letter encoding is tested for their goodness of fit to the encoded letter string. The verification stage in such models, however, does not rely specifically on spelling as the verification criterion.

in a verification stage. These assumptions lead to a general model of the reading-spelling relationship depicted in Fig. 2.2. The reading-spelling relationship, as shown in Fig. 2.2, is one based on access to lexical representations shared by the two processes. These representations (for skilled readers) contain bonded orthographic and phonological elements that are contacted by orthographic inputs (reading) and phonological inputs (spelling). Both reading and spelling contain a verification process in this model. In reading, orthographic forms activate phonological forms (often competing forms) that activate orthographic forms. The orthographic form verifies the word identity. In spelling, phonological forms activate orthographic forms that activate phonological forms that verify the word identity. In both cases, the verification is ordinarily rapid and unconscious; however, the fact that spelling is the retrieval of letter constituents rather than their recognition means that spelling is effortful enough in some situations to create a slow and conscious trace of this process. In skilled reading this is seldom the case. However, in reading unfamiliar words, one occasionally can observe the full-blown version of verification when a reader tries a pronunciation, compares it with the visible spelling, and, recognizing that the pronunciation does not look like the spelling (i.e., this pronunciation is usually spelled some other way), tries again. In the context of this model, we can reconsider the question of why spelling is generally more difficult than reading. Bosman and Van Orden
Fig. 2.2. The spelling-reading relationship. Both processes use a lexical representation that contains orthographic (O) and phonological (Ph) constituents. Both spelling and reading use both sets of constituents, and both have a verification stage.

(chap. 10, this volume) argue that English spelling is more difficult because of the greater variation in phonological-to-spelling mappings than in spelling-to-phonological mappings. This assumption is reflected in the difference between the O->Ph and the Ph->O connections in Fig. 2.2. However, this difference is only part of the story, and it is not clear that it is the major part. As argued previously, the dramatic difference in the retrieval frequency of orthographic lexical forms compared with the recognition frequency of orthographic lexical forms can produce the advantage of reading over spelling. Finally, it is interesting to return to the issue of orthographic differences in this context. English, Dutch, German, and French all alphabetic orthographies that are topics of discussion in other chapters of this volume vary in their spelling regularity (i.e., the direction of letter sequence to phoneme predictability). Dutch and German are very regular (shallow orthographies); French is comparable in this respect but in the other direction phonology to spelling is highly inconsistent (see Totereau, Thevenin, & Fayol, chap. 6, this volume). Italian, discussed earlier in this chapter, is quite consistent in both directions; English has considerable inconsistency in both directions. In comparisons of reading and spelling across orthographies, it may not be enough to note just the shallowness of the orthography as it has been defined in recent years since the work of Frost, Katz, and Bentin (1987). It is necessary to recognize the bidirectional nature of spelling-phonology relationships. One might try to correct the situation by referring to shallow phonologies (e.g., Italian) and deep phonologies (e.g., French and English) as well as to deep and shallow orthographies. The depth of the phonology would be the extent its pronunciations, as opposed to its morphology or other factors, control spellings. To a considerable degree, it is the phonology-spelling conventions over the centuries that have led to spelling-phonology inconsistencies. (The influence goes the other way as well; the way words get spelled influences the course of their pronunciation changes.) Nevertheless, we should probably resist the temptation to expand the deep-shallow distinction in this way because it suggests a misleading view of phonology that it mainly serves spelling, and if it serves it well, then phonology is shallow. This appears to get things backward to some extent. Instead, we can refer generally to the transparency of an orthography. This transparency has two components: the transparency of the phonology through the spelling and the transparency of the spelling through the phonology. Orthographies can be further characterized as symmetrically transparent or asymmetrically transparent. It is interesting that there seem to few cases in which the transparency asymmetry favors phonology to spelling over spelling to phonology. Most cases seem to be exemplified by French, in which a reasonably transparent reading process accompanies an opaque spelling process. This

appears to be a consequence of the historical development and pattern of use of full (consonant plus vowel) alphabetic writing systems. (The vowelless orthographies, e.g., Hebrew, may reverse this asymmetry.) Summary Spelling is a psycholinguistic problem involving multilayered linguistic units (morphology and phonology) and writing units. Writing systems constrain the general form of the mapping between units, but all writing systems, including nonalphabetic ones, have evolved to encode speech as well as meaning. Within alphabetic writing systems, linguistic constraints are embedded at different levels. Well-known examples from Italian illustrate how these constraints can affect reading and spelling at fairly abstract levels. The relationship between spelling and reading is one of shared lexical representations and different processes. Implications of a model of reading, the R-I model, suggest that both orthographic and phonological constituents play roles in both reading and spelling. Furthermore, a verification process appears to be part of both spelling and reading. Because this verification process combines information from spelling and reading, it gives specific definition to the claim that reading and spelling are similar. References Besner, D. (1987).

Chapter 3 The Cognitive Neuropsychology of Spelling Pascal Zesiger University of Geneva Marie-Pierre de Partz University Hospital of St.-Luc, Brussels Neuropsychologists began to get truly interested in spelling in the 1980s. Until then, the dominant position was that the production of written language1 was essentially dependent on the mechanisms responsible for the production of oral language. Consequently, the disorders of written production the agraphias2 were mainly viewed as being secondary to the deficits affecting oral language the aphasias resulting themselves from lesions of the left hemisphere. Nonfluent agraphias were usually associated with frontal lesions and fluent agraphias with more posterior lesion sites (Benson & Cummings, 1985; Hécaen, Angelergues, & Douzenis, 1963). However, even if most authors admitted that the intensity and the types of disorders affecting the oral and the written domains could vary (Marcie & Hécaen, 1979), the existence of selective deficits of written production, called pure agraphias, was difficult to conciliate with this perspective. That is why some authors, following Exner (1881), hypothesized the existence of an autonomous center for writing located in the base of the second frontal convolution. 1 The production of written language requires a set of pragmatic, syntactical, semantic, and lexical processes as well as perceptuomotor mechanisms allowing the movements necessary for the production of letters in the graphic space of the page. We limit ourselves to considering the processes responsible for the generation of strings of graphemes forming words or pseudowords. 2 The term agraphia has been used to qualify the disorders of different aspects of written production. A distinction was usually drawn between aphasic agraphia (deficits of the linguistic aspects), apraxic agraphias (disorders related to the production of letters), and spatial agraphias (disruption affecting the arrangement of letters in graphic space).

After the publication of Marshall and Newcombe's (1973) study on reading, researchers started to analyze differently the errors produced by brain-damaged patients by referring to an information-processing model. The adoption of a cognitive perspective in neuropsychology, more focused on the specification of the processes involved in a certain behavior than on the definition of the relation between faculty and substrate, modified the viewpoint on spelling considerably. The presentation of these new concepts constitutes the essential part of this chapter. First, we discuss the domain specificity of spelling and describe the cognitive architecture underlying this capacity. Second, we examine the developments that have occurred in this domain over the last 15 years. Third, we present some issues that are currently subject to discussion. The Specificity of the Spelling Processes Several studies have shown that acquired disorders of spelling were not necessarily associated with disruptions of oral language. For instance, the analysis of the files of hundreds of patients, done by Basso, Taborelli, and Vignolo (1978), revealed that some patients admittedly, a minority were affected by a selective alteration of written production without impairment of oral production or, conversely, presented a deficit of oral production preserving written production. These data are consistent with the description of other forms of dissociation, qualitative in nature. Assal, Buttet, and Jolivet (1981) described a patient presenting both oral and written production disorders. These deficits expressed themselves very differently in the two modalities, with an oral impairment being similar to a Wernicke's aphasia and a written disorder recalling the characteristics of a Broca's aphasia. Finally, we point out that various studies showed that spelling disorders were not systematically associated with reading impairments (i.e., Baxter & Warrington, 1985). Overall, these investigations converged towards the notion of specificity of at least a part of the spelling processes that appear to be liable to be selectively affected by a brain lesion. The Cognitive Architecture of Spelling Processes The next step was made possible thanks to the publication of two cases that became famous in neuropsychological literature. Beauvois and Dérouesné (1981) described a French-speaking patient (RG) presenting an important spelling deficit. Detailed investigations of RG's difficulties revealed the following characteristics: (a) Words produced by RG contained numerous errors, whereas the written transcriptions of dictated pseudowords were

all correct; (b) the more the words contained orthographic ambiguities,3 the more they were prone to errors; (c) orthographic regularity interacted with word frequency low-frequency words were more sensitive to orthographic regularity than highfrequency words; (d) neither the syntactical class (nouns, verbs, function words, etc.) nor the length of words seemed to affect the patient's performance; and (e) the paragraphias produced by RG were mostly phonologically plausible errors (soeur-> seur, rameau-> ramo). This patient presented a disorder that was limited to the production of familiar words with a preservation of the capacities to generate pseudowords. The terms surface dysgraphia (or lexical or orthographic dysgraphia) are generally used to refer to this type of deficit, later reported by several other authors (Baxter & Warrington, 1987; Goodman & Caramazza, 1986b; Hatfield & Patterson, 1983; Roeltgen & Heilman, 1984). On the other hand, Shallice (1981) described an English-speaking patient (PR) presenting the opposite pattern, known as phonological dysgraphia. PR experienced considerable difficulties in writing dictated pseudowords even if they were simple (18% correct responses), whereas his production of familiar words was mostly spared (94% correct responses). The errors produced by PR were nonphonological (*bup-> coz). Complementary experiments enabled Shallice to show that PR's disorder in the production of pseudowords was due to a double deficit: (a) segmenting auditorally presented pseudowords into isolated phonemes; and (b) transcoding isolated phonemes into graphemes. Other patients have been similarly described (Bolla-Wilson, Speedie, & Robinson, 1985; Roeltgen, Sevush, & Heilman, 1983). Patients RG and PR constitute what is called in neuropsychology a double dissociation: In one of them, the capacity to perform task X is impaired, but his capacity to execute task Y is preserved. In the other, the opposite pattern is observed. On the basis of this double dissociation, following Morton (1980), several authors suggest that spelling processes are made up of two main procedures, or routes: an addressing procedure (or lexical route), responsible for the generation of familiar words, and an assembling procedure (or phonological route), responsible for the production of nonfamiliar words and of pseudowords (see Fig. 3.1). It was initially admitted that these two routes function independently from each other. According to this model, a set of processes is necessary in order to generate a sequence of graphemes in response to a dictated stimulus. The first processing level, which would be common to both procedures, analyzes the phonetic or acoustic features of the stimulus. When it is a familiar word, 3 The orthographic ambiguity of a word corresponds to the presence of sounds liable to be translated in various ways in the graphemic code (e.g., beak could be spelled beek). It is distinguished from orthographic irregularity, which denotes the presence of exceptional phoneme-grapheme correspondences in the language (e.g., the /m/-> mn in autumn). In what follows, we do not draw a distinction between these two forms of irregularity.

Fig. 3.1. Schematic diagram representing the minimal cognitive architecture of the spelling processes. the signal resulting from this analysis activates the phonological representation of the word in a phonological input lexicon. The activated unit (or, more correctly stated, the unit for which activation level is the highest because this model rests on the principle of passive parallel activation) within this lexicon transmits the information necessary for the activation of the meaning of the word stored in a semantic system.4 This activation is then transmitted to an orthographic (or graphemic) output lexicon that would contain the orthographic representations of words. The selected sequence of graphemes is temporarily stored in an orthographic (or graphemic) buffer whose function is to maintain a trace of this sequence during the processing time necessary to the processes responsible for the transformation of graphemes into sequences of movements leading to the production of letters (peripheral processes). 4 This would be the first level activated in spontaneous writing production.

When the dictated stimulus is unknown to the participant, it would temporarily be stored in a phonological buffer. According to some authors, before the representation is placed in this buffer, it has to be transformed from the phonetic code into the phonological code. It is most likely during this operation that the segmentation of the stimulus into phonemes is performed. Once the string of sounds is stored in this working memory, a process of conversion from sounds to letters (or from phonemes to graphemes) constitutes (or assembles) a string of graphemes that is temporarily stored in the orthographic buffer before being processed by motor processes. This model of the normal functioning of spelling processes allows interpretation of the two classes of deficits reported previously (Ellis, 1982; Margolin, 1984). Surface dysgraphias can be explained by a disruption of the addressing procedure, and phonological dysgraphias can be explained by an impairment affecting the assembling procedure. It should be highlighted that the damage can be located at various levels of these procedures (and possibly at more than one level) within the components themselves or within the connections between modules. Depending on the affected level, the expected pattern of performance following a damage of a procedure can considerably vary. Besides, impairments involving a dysfunction of the two routes have also been described. Several authors reported the existence of a deficit, under the name deep dysgraphia, that affects the production of words as well as the production of pseudowords (Bub & Kertesz, 1982; Hatfield, 1985; Nolan & Caramazza, 1983). Several types of errors are observed with words: (a) semantic errors, in which the produced word has a related meaning with the dictated word (star-> moon, grass-> green); (b) morphological errors, in which the produced word is a morphological derivative of the dictated word (relation-> relating); and (c) visual errors, in which the produced word is visually similar to the dictated word (charge-> chance). Finally, two additional phenomena have been described in this type of disorder: the effect of the degree of imagery of words and the effect of their syntactical class. For the first one, words with a high degree of imagery (e.g., forest) are generally less affected by a lesion than words with a low degree of imagery (e.g., norm). For the second one, the proportion of errors varies as a function of the syntactical class they belong to: nouns, verbs, adjectives, function words, and so on. The interpretation of these phenomena necessitates a more in-depth examination of the model and of the hypotheses underlying it. The Specification of Processes In this section we focus on the multiple processes of spelling that we try to define, on the one hand, as a function of the type of errors observed after their damage and, on the other hand, as a function of their sensitivity to various factors.

The Addressing Procedure We limit ourselves to considering the semantic system and the orthographic output lexicon. An impairment of the semantic system leads, within the framework of spelling disorders, to various deficits. The apparition of semantic errors is indeed expected. These errors have been used to support the hypothesis of a categorical organization of this system. The production of semantic errors can also be interpreted as a disruption of the connections between the semantic system and the orthographic lexicon. What distinguishes these two possibilities is that, in the first case, semantic errors should be observed in all language modalities (oral and written comprehension and production), but in the second case, such errors should only appear in written production. The occurrence of semantic errors specific to written production seems to imply an alteration of the assembling procedure as well (Miceli, Capasso, & Caramazza, 1994). The effect related to the degree of imagery of words is usually thought to reflect another characteristic of the organization of the semantic system. Thus, words with a high degree of imagery have more specific or more detailed meanings or are represented by more constituting features than words with a low degree of imagery. Alternatively, they possess a different code than words with low levels of imagery (visual vs. propositional). These properties make words with a high degree of imagery more resistant to a lesion. It is usually considered that an impairment of the orthographic lexicon results in the production of two types of errors. If the representation of the word is entirely lost (or unaccessible), its generation is assumed by the assembling procedure. Consequently, the production contains phonologically plausible errors that give us information about the functioning of the assembling procedure, which is analyzed later. On the other hand, if the representation is only partially damaged, we should observe errors that reflect the degradation of this representation (pyramid->pyminal, orchestra->orchestra) (Ellis, 1982, 1984; Morton, 1980). For Patterson (1988), however, this last error type instead reflected problems of information degradation during its transfer from the orthographic lexicon to the orthographic buffer. A functional lesion of the orthographic lexicon necessarily leads to a disorder characterized by the presence of an effect of orthographic regularity. This effect expresses the capacity of the assembling procedure to correctly spell regular words by the application of phoneme-grapheme (P-G) conversion rules. The frequency effect is also associated with a lesion of this component. It expresses a certain form of resistance to damage to the most frequent words. Finally, the effect of the syntactical word class has been interpreted as reflecting the categorical organization (by syntactical class) of this lexicon (Baxter & Warrington, 1985; Caramazza & Hillis, 1991). A last phenomenon regarding the addressing procedure has been reported: It is homophonic confusions (their-> there, none-> nun) produced

by some patients. Such errors can also be observed in the written production of normal participants (what is called ''slips of the pen''). The occurrence of this type of paragraphias suggested the idea that the representations stored in the orthographic output lexicon can be activated by phonological representations, without semantic mediation. The hypotheses concerning this nonsemantic lexical route differ, depending on the authors: Goodman and Caramazza (1986a) postulated the existence of a direct connection between the phonological input lexicon and the orthographic output lexicon (route a on Fig. 3.1), whereas Patterson (1986) suggested that this route would pass via the phonological output lexicon (route b). For the time being, data from the literature do not allow a choice between these alternative hypotheses. It should also be mentioned that recent data collected with patients presenting an impairment of the orthographic buffer suggested complementary hypotheses concerning the structure of orthographic representations. We present them in "The Orthographic Buffer," the section concerning the disorders associated with this buffer. The Assembling Procedure The phonological route can also be altered at diverse loci. As reported previously, patient PR experienced difficulties in segmenting auditorally presented pseudowords into isolated sounds and in converting isolated sounds into letters. These two difficulties do not necessarily coexist. Several patients displaying the same type of deficit as PR seem to only suffer from an inability to segment an acoustic continuum into isolated sounds without having difficulties in converting isolated sounds into letters (Bolla-Wilson et al., 1985; Roeltgen et al., 1983). Moreover, a different impairment of this procedure was described by Caramazza, Miceli, and Villa (1986). Their patient was affected by very specific spelling disorders. He produced errors on pseudowords but not on words. These errors were almost all letter substitutions that were characterized by a high phonological similarity (/d/-> /t/, /p/-> /b/). According to Caramazza and colleagues, this deficit was attributed to a dysfunction of the phonological buffer that resulted in a deterioration of the representation that is stored in it. This phenomenon was also found in reading and in repeating pseudowords, which would indicate that this buffer is also involved in these behaviors. With the aim of specifying the functioning of the P-G conversion system, in-depth studies were performed with patients presenting a quasi-abolition of the addressing procedure. The analysis of the productions of such a patient allowed Goodman and Caramazza (1986b) and Goodman-Schulman and Caramazza (1987) to show evidence of two main phenomena: (a) In cases when different graphemes (or sets of graphemes) correspond to the

same phoneme (/i:/-> ea, ee, etc.), the P-G conversion system operates in a probabilistic manner by reproducing the frequency of occurrence of the P-G correspondences in the language; (b) this component is able to select the adequate graphemic option as a function of the within-syllable position of the grapheme as well as of the context in which the grapheme is placed. These constraints allow the hypothesis that this module does not process each phoneme independently. Goodman and Caramazza (1986a, 1986b) suggested that the processing unit is at least as large as a syllable. It should be noted that the research done on this topic did not always result in such clear evidence (see Baxter & Warrington, 1987, 1988). These discrepancies could be related to the use, in some patients, of residual capacities of the addressing procedure (Sanders & Caramazza, 1990). The Orthographic Buffer It was originally thought that the orthographic buffer coded two aspects: the graphemes' identity and their order. Given the temporary nature of this stock, it was supposed that the trace held in this working memory underwent a relatively rapid decay. The main factor associated with this level was word length: the longer the word, the longer the time necessary for preparing and executing the movements tracing the letters.5 Caramazza, Miceli, Villa, and Romani (1987) defined the criteria characterizing a deficit of the orthographic buffer. Thus, an impairment of this component should alter the production of words as well as pseudowords. Similarly, it should affect written production whatever the response modality (writing, oral spelling, typing, etc.). These phenomena are related to the fact that the orthographic buffer is common to both routes and to the various production modalities. Moreover, the factors relative to the two procedures (lexical frequency, syntactical class, frequency of the P-G correspondences, etc.) should not affect the patient's performance. The errors should be mainly letter substitutions, omissions, transpositions, and additions. Finally, an effect of word length should be observed (more errors on long words than on short ones). Several patients presenting exactly this type of pattern have been described in the literature. Furthermore, Hillis and Caramazza (1989) reported the existence of an interesting double dissociation concerning two patients displaying a damage to the graphemic buffer: The first patient committed more errors on the initial part of words, and the second one produced more of them on the final part of words. On this basis, these authors suggest that, although graphemes are represented in this buffer in an abstract manner (that is to say in a code that is not 5 However, this simple principle is questioned by some authors who hypothesize a possible refreshing (or reactivation) of this trace via one or the other routes (see Miceli, Silveri, & Caramazza, 1985; Nolan & Caramazza, 1983).

physical or visual), their order is coded in a spatial structure liable to be neglected either on the right or on the left. Several studies that offer more precise hypotheses on the representations contained in the orthographic buffer have been put forward. Badecker, Hillis, and Caramazza (1990) studied the performance of an English-speaking patient (DH) displaying an impairment of the orthographic buffer. DH is the patient mentioned earlier who produced most of his errors on the final part of words. The authors submitted DH to writing and dictated oral spelling tasks of words possessing various morphemic structures. These words either contained a single morpheme (e.g., ballad), two morphemes (root and affix, e.g., fixed, games) or were compound words (newspaper, everything). The results showed, on the one hand, bimorphemic words of equal length generally contained fewer errors than monomorphemic ones. On the other hand, the errors observed on bimorphemic words were usually located at the end of morphemes and not at the end of words. This proved true only in cases when the composition rules of morphemes were transparent (affixes called productive: e.g., motionless = motion + less). These results suggested that the unit processed at this level was a morpheme rather than a word. For Badecker and collaborators, this also applied for the representations contained in the orthographic output lexicon. Moreover, Caramazza and Miceli (1990) analyzed the performance of an Italian-speaking patient (LB) presenting an orthographic buffer deficit in the written production of a large corpus of six-letter words. Their analysis revealed the following facts: (a) Words with a complex consonant vowel (CV) structure (e.g., scuola = CCVVCV) contain more errors than words with a simple CV structure (e.g., tavolo = CVCVCV); (b) letter substitutions and transpositions by LB always conform to the rule "a consonant for a consonant, a vowel for a vowel"; (c) the errors on groups of letters that form one or more sounds (e.g., in Italian, the sequence SC can be pronounced either /sk/ or / /) are identical, indicating that the basic unit would be the grapheme and not the phoneme; and (d) geminate letters are extremely resistant to errors. On the basis of these results, and by analogy with current descriptions of phonological representations, the authors suggested that the orthographic representations possess a multidimensional structure defined by four tiers: the graphemes' identity, their CV status, the grapho-syllabic boundaries, and an indicator of geminate graphemes (see Fig. 3.2a). Very recently, McCloskey, Badecker, Goodman-Schulman, and Aliminosa (1994) described an English-speaking patient with a lesion of the orthographic buffer (and most likely also of the orthographic output lexicon) who produced, conversely to LB, more errors on words containing geminate letters than on words that did not contain doubled letters (e.g., dress-> drees). In order to account for this patient's performance pattern, the authors proposed a model of the structure of orthographic representations that is a bit

Fig. 3.2. Structure of the orthographic representation of the word witness according to Caramazza and Miceli (1990) and McCloskey et al. (1994). different from the previous one. It is a multidimensional structure coding the following tiers (see Fig. 3.2b): the graphemes' identity, their position (represented by X), their number, and their CV status. Consequently, McCloskey et al. did not make any assumption on the representation of the grapho-syllabic boundaries and suggested that the position of the graphemes within the word be explicitly defined, even for geminate letters. It is probably too early to try to choose between these two alternative models, which are very similar to each other. Nevertheless, it should be noted that data collected by other researchers fit quite well in one or the other of these frameworks, in particular the ones concerning the specification of the CV status (Cubelli, 1991) and the special mode of representation dedicated to geminate letters (Venneri, Cubelli, & Caffarra, 1994). Some Themes for Discussion Phonological Route or Lexical Analogy? The first questions about the dual-route model were proposed by Campbell (1983) who argued that normal subjects did not use a simple phoneme to grapheme transcription in order to spell pseudowords. In her experiment, she submitted students to a modified lexical decision task. The participants

page_49
next page > Page 49
first had to decide if an auditorally presented stimulus was a word. If it was not a word, they had to orally spell the heard nonword. Campbell's demonstration rests on the fact that when a word such as brain is presented before a pseudoword such as /prein/, a majority of participants have a tendency to spell the pseudoword prain. Conversely, if the word crane is presented shortly before, they spelled the same pseudoword prane. According to Campbell, this result indicates that in order to spell pseudowords, participants used their knowledge concerning words and not a sound-to-letter conversion system. Pseudowords are consequently spelled by analogy with words existing in the participants' orthographic lexicon. Barry and Seymour (1988) criticized several methodological issues of this experiment and replicated it with some modifications of the aspects that troubled them. The results that they obtained differ a bit from those of Campbell: They observed not only an effect related to lexical influence but also an effect of the frequency of the sound-to-letter correspondences. There is no interaction between these two effects. According to Barry and Seymour, these results are compatible neither with the model of lexical analogy nor with the classical dual-route model. Therefore, they propose an alternative model, called interactive, which is based on the existence of two routes functioning in parallel. The processing of any stimulus (familiar or not) simultaneously involves the lexical route and the phonological route. The presentation of a word activates its representation in the orthographic lexicon as well as the various P-G correspondences that characterize it in the P-G conversion system. This activation explains why these correspondences are more likely to be selected in the subsequent generation of a pseudoword. The notion of a parallel activation of both routes was also proposed by Hillis and Caramazza (1991) and by Miceli, Capasso, and Caramazza (1994) under a different form. These authors suggest the existence of a connection between the P-G conversion system and the orthographic output lexicon. Their hypothesis is that the activation and the selection of an orthographic representation in the orthographic output lexicon is realized on the basis of the sum of the activations coming from both the semantic system and the P-G conversion module. The influence of the assembling procedure is small in normal time. Conversely, it could be determining when, for one reason or another, the information coming from the semantic system is decayed or delayed. The corollary of this proposition is that semantic errors specific to the written output modality should be observed only in cases of joint damage to the addressing procedure and to the assembling procedure. This prediction seems to be confirmed by an examination of the published cases of patients committing semantic errors specific to written production: All of them presented difficulties affecting the sound to letter conversion.

Are Orthographic Input and Output Lexicons Independent? In the cognitive models of reading, the existence of an orthographic input lexicon allowing recognition of visually presented familiar words is usually postulated. The independence of this lexicon with regard to the orthographic-output lexicon (used in spelling) is discussed in the normal subject as well as in the brain-damaged patient. Experimental results obtained with normal subjects did not until now provide a clear answer to this question. Indeed, Monsell and Banish (cited in Monsell, 1987) found that the writing of words, without seeing them, did not facilitate performance by the participants in a visual, lexical-decision task performed later. This suggests that orthographic representations used for input and for output are independent. On the other hand, in a second experiment, the authors observed a facilitative effect of writing a dictated word on the ability of the participants to match it with a visual definition and to recognize it in a visual lexical decision task. These results suggest that having participants produce an orthographic form of a word facilitated its recognition only when it could be viewed. In any case, whether a single orthographic representation serves both input and output becomes a complex question in view of such data. Data coming from pathology have not necessarily settled this question. Some authors plead in favor of a single orthographic lexicon (Allport & Funnell, 1981; Coltheart & Funnell, 1987). From this point of view, all the representations are stored in a central orthographic lexicon and the errors observed in reading and/or in writing are associated with an alteration of the functionally distinct procedures of input and output. The main argument evoked by these authors is the frequent association between surface dyslexia and dysgraphia. However, authors favoring the hypothesis of independent lexicons cite the existence of dissociations between reading and writing skills in the same patient (Baxter & Warrington, 1985; Beauvois & Dérouesné, 1981). For instance, patient RG, mentioned earlier in this chapter, was presenting, in addition to a surface dysgraphia, a deep dyslexia. Among all the dissociations registered in the literature, it seems that surface dysgraphias can appear in the absence of a surface dyslexia, whereas the opposite pattern does not appear to have clearly been observed so far. There are, however, two studies (Howard & Franklin, 1988; Kremin, 1989) that reported the cases of patients presenting a surface dyslexia associated with a deep dysgraphia, a dissociation that, at first sight, seems to indicate that the orthographic representations can be preserved for output but not for input. However, it seems difficult for us to support the hypothesis of the independence of orthographic lexicons for input and for output on the basis of this dissociation, for two reasons. First, the presence of a surface dyslexia does not necessarily imply the presence of a deficit at the level of the

page_51
next page > Page 51
orthographic representations; the patient can indeed be led to use the assembling procedure if he or she experiences difficulties in accessing the output phonological lexicon, which would leave the orthographic representations intact. Second, deep dysgraphia seems a bad candidate for dissociation given the fact that in this type of disorder, there is not only an important alteration (of variable location and degree) of the assembling procedure but also additional deficits of the addressing procedure, in particular at the level of the output orthographic representations. Thus, the alteration of a unique orthographic system could very well be expressed by regularization errors in reading because the assembling procedure can, up to a certain extent, compensate for a deficit in accessing orthographic representations and, at the same time, not appear in writing. Indeed, in deep dysgraphia, the alteration of orthographic representations can lead to the production of nonresponses or to the production of semantic or visual paragraphias because the assembling procedure is unable to compensate for the deficits of the addressing procedure. Thus, the only satisfying demonstration of the independence of the two lexicons appears to result from the report of a surface dyslexia (involving the level of orthographic representations) that either is not associated with a spelling disorder or is associated with a phonological dysgraphia in which the spelling of words is almost entirely correct. For the supporters of a unique orthographic lexicon, the sense of this dissociation is compatible with the hypothesis that they defend. Indeed, the association of a surface dyslexia and of a surface dysgraphia depends, according to them, on the severity of the deficit at the level of the unique orthographic lexicon: The more severe the deficit, the more it impairs the activation of orthographic representations, simultaneously affecting writing and reading. Contrary to this, if the deficit is moderate, it could appear only in writing because the activation level required for matching a visually presented item with its stored representation (recognition) is less important than the activation level required for producing a representation in the absence of an external sensory input (recall). The orthographic predictability is then higher in the reading task than in the writing task and accounts for the fact that a deficit in a unique orthographic lexicon has more impact on writing than on reading, with a larger number of words enabling efficient processing by an assembling procedure. Acquired and Developmental Spelling Disorders Besides acquired disorders that have been discussed to this point, developmental disorders have also been studied in the domain of spelling (Campbell & Butterworth, 1985; Seymour, 1987; Temple, 1986). Most researchers interested in this theme use a double theoretical framework: functional models, described in this chapter, and specific models of reading and spelling

acquisition. These are presented in several chapters in this volume (see Treiman & Cassar, chap. 4; Ehri, chap. 13; Ellis, chap. 14; and Rieben and Saada-Robert, chap. 15). We recall that the supporters of these models hypothesize that the progressive mastery of reading and spelling involves several phases characterized by the use of different strategies. For instance, Frith (1985) assumed the existence of three successive strategies: a logographic strategy based on a global, visual representation of the word; an alphabetic strategy involving a process of phonological mediation (which can be set in parallel with the assembling procedure); and an orthographic strategy based on a morphemic representation of words (addressing procedure). There are divergences between authors concerning whether all strategies are used in spelling (the logographic strategy in particular could be specific to reading), whether these strategies are elaborated and used successively or simultaneously, and whether alternative strategies (such as the strategy of lexical analogy) can be identified. The literature concerning developmental spelling disorders indicates that some features described in brain-lesioned adults can also be found in learning disabled children. Thus, the performance of several participants, reported by Temple (1986) and by Seymour (1987), is characterized by the production of phonologically plausible errors and by an advantage of regular words over irregular words. This type of deficit evokes the surface dysgraphia described in adults. In the framework of developmental models, this disorder has generally been interpreted in terms of use of an alphabetic strategy related to the child's inability to move on to an orthographic strategy. The opposite pattern has also been reported under the same name for adults (phonological dysgraphia). This disorder is characterized by considerable difficulties in spelling pseudowords and by the production of mostly nonphonologically plausible errors (Campbell & Butterworth, 1985; Seymour, 1987; Temple, 1986). According to these authors, these participants are not able to elaborate an adequate alphabetic strategy. Those whose difficulties are the most severe use a logographic strategy, whereas those presenting more limited deficits use an orthographic strategy. Beyond these very general considerations, it seems that a more detailed examination shows evidence of numerous divergences between acquired and developmental disorders. It should be noted that the deficits reported in disabled children are rarely as selective as those described in brain-damaged adults even if participants reported in the literature are not representative of the daily clinical practice. As mentioned by Seymour (1987), it is necessary with children to distinguish the primary source of the deficit from its effects on later development. The presence of a disrupted process can be a handicap, but it is also liable to stop or to modify the development of other processes that rely on incomplete or incorrect information generated by this component. Besides, current data suggest that the child ("normal"
< previous page

as well as disabled) uses more than one strategy at a time each strategy being more or less functional. This phenomenon could also explain part of the differences observed between acquired and developmental disorders. Future studies should aim at going beyond these general analogies to supply detailed indications on the constitution of the processes responsible for spelling and on the qualitative and quantitative changes occurring throughout the process of acquisition. Spelling and Connectionism A last point of discussion concerns the connectionist approach, regularly presented as an alternative of the classical cognitive or symbolic models (Rumelhart & McClelland, 1986). Several authors developed models that simulate various aspects of human performance, both normal and pathological, in the field of spelling. For instance, two recent studies have been dedicated to the capacities of neural networks, possessing neither a lexicon nor a set of explicit P-G conversion rules, to generate sequences of graphemes in response to sequences of phonemes (Brown & Loosemore, 1994; Olson & Caramazza, 1994). The architecture of these models is formed by three layers of units: an input layer representing the phonological form of words, an output layer coding the orthographic forms, and a hidden layer functioning as an aid in the establishment of input and output correspondences. A learning algorithm enables the network to modify the weight of the connections between units so as to progressively increase the probability of generating correct responses. The various implementations of these types of models proved able, after a period of learning during which they were presented with a corpus of words, to produce the correct spelling of these words, both regular and irregular, with a high percentage of success. Furthermore, when the spellings generated by the network were not accurate, the networks usually proposed orthographic forms that were phonologically plausible (e.g., syntax-> sintax), thus simulating the behavior of a human participant. Besides, these networks also proved liable to generalize their knowledge to words that had not been previously presented. Finally, lesions of these networks (performed either by introducing sources of noise in the weight of the connections after learning or by limiting the number of hidden units before learning) resulted in performance profiles that were similar to certain deficits described in brain-damaged patients (Olson & Caramazza, 1994) or in dysgraphic children (Brown & Loosemore, 1994). In particular, a dissociation between performance on regular words (relatively preserved) and performance on irregular words (affected) was observed. Houghton, Glasspool, and Shallice (1994) proposed a connectionist model simulating the phenomena associated with the serial order of spelling at-

tributed, in symbolic models, to the existence of an orthographic buffer. These authors showed that it was possible to account for some aspects of normal and pathological performance by a three-layer model coding the word, the graphemes, and a competitive filter enabling the successive activation of the different graphemes forming the word. The capacity of connectionist networks to learn to spell regular and irregular words and, to a certain extent, to generalize their knowledge to new words constitute an important challenge for the models based on the existence of multiple routes involving separate processes. The connectionist approach is not without problems however. In particular, as noted by Olson and Caramazza (1994), the performance of the networks appears to be highly related to the mode of representation chosen. Moreover, "lesioning" these networks results in the emergence of only certain aspects of the deficits observed in brain-damaged patients. For the time being, it cannot be claimed that the other characteristics and the other patterns described in the preceding pages will emerge from "lesions" made to these networks. The dialogue between symbolic and subsymbolic models in the field of spelling is now open. As suggested by some authors, these two types of models are not necessarily incompatible, and the dynamic that is now established between the supporters of the two approaches will certainly be beneficial to the advancement of concepts of spelling in the domain of neuropsychology and, more generally, of psychology. Conclusion This brief examination of the studies done with a cognitive perspective in the neuropsychology of spelling allows a first evaluation. Within less than two decades, researchers have managed to elaborate consistent, empirically testable, models that present the advantage of integrating a considerable number of observations and experimental facts. As we have attempted to show, these models are still being elaborated and, are, therefore, liable to be modified and enriched at any moment. It is obvious that much research is still necessary in order to define more precisely the structure and the functioning of each of the components as well as their connections. Nevertheless, these models begin to have an impact on clinical neuropsychological practice, in particular on the evaluation and remediation of spelling disorders. A methodology of clinical evaluation in which the theoretical models are used by clinicians to make inferences about the functional origin of individual, pathological behaviors is developing. A number of recent studies (Behrmann, 1987; de Partz, Seron, & Van der Linden, 1992; Hatfield, 1982) showed that a cognitive interpretation can be used in developing a remediation goal in two ways: By specifying the impaired processes

to which the training should apply (on the one hand), and by specifying the preserved components that can (possibly?) compensate for the impaired components (on the other hand).

Chapter 4 Spelling Acquisition in English Rebecca Treiman Marie Cassar Wayne State University Having been given the opportunity to write a short chapter about spelling acquisition in English, we are pleased to report that this task is now near to impossible. The reason we are happy is that, in the past, the field of spelling suffered from a dearth of research. There was much more work on the acquisition of reading and word recognition than on the acquisition of writing and spelling. However, the body of research on spelling in English-speaking children is now so large that it would be foolish to presume to do it justice within a single chapter. Given this limitation, we chose three main topics for discussion. These are the use of letter names as an entry into the writing system, young children's knowledge of the orthographic patterns of their language, and children's use of morphological strategies to guide their spelling. We chose these three topics because each plays a major role in existing theories of spelling development. We review experimental evidence to suggest that young spellers have more knowledge in each of these areas than portrayed by existing theories. Children's knowledge, we argue, provides a foundation for the development of spelling skills. To accomplish our goal, it is first necessary to review what the existing theories have to say about spelling development. Current research on the topics of letter-name spellings, knowledge of orthography, and morphological knowledge is then discussed. In the final section, we address the implications of the findings for views of spelling development.

Theories of Spelling Development Henderson (1985) outlined five stages of spelling development. The first stage, preliterate writing, begins almost as soon as a child starts to make marks with a crayon or pencil. A child's ''writing'' at this stage may resemble scribbles more than writing. The child understands that writing is different from drawing but not that writing represents speech. When children do begin to realize that writing is a way to communicate speech and that letters symbolize the sounds in words, they are considered to be entering the second stage of spelling development. This second stage is called letter-name spelling. Gradually, the child has become aware of sounds and of the letters used to represent them. The child has also learned the names of the letters of the alphabet. Often a child will write a letter to represent the sounds of the letter's name. For example, the words mess and help may be spelled MS and HLP, respectively, with the letters s and l standing for their names, /es/ and/el/. (Throughout this chapter, we use capital letters to refer to children's spellings of words or nonwords.) Children do not represent in their spellings sounds that they have difficulty accessing as separate units, such as the /m/ and /n/ in the words bump and want. For the child, the sound of the vowel plus the /m/ or /n/ appears to be one. Because children do not yet know all of the conventions of the writing system, their spellings contain these apparently odd errors. Henderson stated that children use a phonetic or sound-based strategy to spell words that they do not know throughout the first and second spelling stages and into the third stage, called the within-word pattern stage. By the time children reach the within-word pattern stage, they have begun to learn words by sight through their reading. Basically, the term sight words refers to an acquired pool of memorized spellings. According to Henderson (1985), children usually spell sight words correctly once they have acquired these words. Not until a considerable number of sight words are learned do they begin to influence children's spellings of novel words. As children's writing starts to change as a result of this influence, children are considered to be entering the within-word pattern stage. This stage is marked by the correct spelling of short vowels, the use of silent markers such as final e for long vowels, and the correct spelling of clusters such as st, dr, and tr. The letters m and n that were previously missing in words such as bump and want now appear. Children's knowledge of sight words helps them to realize that writing does not always involve a one-to-one matching of sound to letters. Children begin to use frequent letter patterns that correspond to sequences of sounds, for example the -ight pattern found in light, might, and fight. After children have begun to learn patterns in conventional spelling and start to use them in their own spellings, they become able to understand

next page >
< previous page
page_63
next page > Page 63
how meaning relations among words are marked in print. Before this, according to Henderson (1985), children's spelling is based on sounds. For instance, letter-name spellers represent the past tense ending -ed with either d, t or id according to its sound, as in PED for pinned, STAPT for stepped, and PLATID for planted. During the initial part of the within-word period, children still choose different patterns depending on the morpheme's phonetic form. Later, children come to understand that the past tense ending has a consistent spelling. "From the third grade on, . . . the role of meaning becomes rapidly more conspicuous" (Henderson, p. 63). The use of double consonants to mark a short vowel characterizes Henderson's (1985) fourth stage, called the syllable juncture stage. Children who are making rapid progress in learning to spell may reach this point during the middle years of elementary school; other children do not reach this stage until later. Children now learn that the presence versus the absence of a double consonant marks the difference between the first vowels of words such as little and title. Other learning at this stage includes the understanding of when and when not to double consonants with the addition of suffixes such as -ed and -ing. The last stage in Henderson's (1985) outline of spelling development is called derivational principles. This stage may begin as early as the late elementary grades for children who are progressing quickly; it begins later for other children and continues throughout a writer's lifetime. As the title of this stage implies, the spelling relations among words in terms of roots, origins, and meanings are further explored. Knowledge of the meaning connections among words such as confide, confident, and confidential aids the speller. These words have similar spelling patterns even though their sounds vary slightly. A very similar sequence for spelling development has been outlined by Gentry (1982), who analyzed the spellings of a precocious youngster who began to write at home without formal instruction (Bissex, 1980). Gentry's depiction begins with the precommunicative stage, when the child has no knowledge of letter-sound correspondence. During this stage, spellings are random letter strings that may include numbers or letter-like marks. Next, the child begins to understand that letters are used to represent sounds. However, spellings start out as incomplete phonetic representations of words. The letter-name strategy mentioned earlier is the hallmark of this second stage, which Gentry called the semiphonetic stage. "Where possible the speller represents words, sounds, or syllables with letters that match their letter names (e.g., R [are]; U [you]; LEFT [elephant]) instead of representing the vowel and consonant sounds separately" (p. 194). Once children can symbolize the entire sound structure of words in their spellings, they are considered to have reached the phonetic stage. All of the surface sound features of words are now represented in spellings. However, "letters are assigned

page_64
next page > Page 64
strictly on the basis of sound, without regard for acceptable English letter sequence or other conventions of English orthography" (p. 195). The fourth stage, called the transitional stage, starts when children become more aware of conventional spellings. Children now employ visual and morphological information in their spelling rather than depend wholly on sound, as they did earlier. Gentry's last stage is simply called the correct stage. Knowledge of the orthographic system and of basic rules is firm. A writer will continue to master uncommon and irregular forms and so errors will occur, but the majority of spellings will be correct. Ehri (1986) outlined three stages describing the development of orthographic knowledge: the semiphonetic, phonetic, and morphemic stages. The characteristics of these stages are very similar to the semiphonetic, phonetic, and transitional stages described by Gentry (1982). Ehri did not include the period before actual alphabetic writing as the initial stage of spelling development, in contrast to Gentry's first precommunicative stage. Although Ehri acknowledged that very young children have some primitive notions about writing, she preferred to begin her description at the point at which children are attempting to write words. Another difference between the stages outlined by Ehri and by Gentry is that Ehri did not include a final stage characterized by correct spelling. She argued that a number of regularities are learned during the morphemic stage, leading to the correct spellings of many words. This learning process is part of the morphemic stage, which continues throughout the writer's lifetime. These three descriptions of spelling development (Ehri, 1986; Gentry, 1982; Henderson, 1985) share some important characteristics. All depict beginning spellers as focused on representing speech sounds in their spellings. Common phoneme grapheme mappings and letter names are believed to guide a child's use of letters and letter sequences at this time. Knowledge about the variety of letter sequences that are possible in English and about when each one should be used develops only after children have established a corpus of sight words. The understanding of meaning relations among words and the use of this knowledge to guide spelling is also a late development. Thus, the theories portray spelling development as a sequence of stages that involve the ability to use different types of information. Young spellers are limited to a few sources of information, namely sounds and letter names. As children progress through the stages, they gain the ability to use other types of information, including orthographic regularities and morphological relations among words. We argue that the existing theories underestimate young children's abilities. Although phonology and letter names play important roles in early spelling, young children also have some budding knowledge about the orthographic regularities of the written language and about the role of morphology in spelling. Children begin to use this knowledge earlier than they

are given credit for in the existing theories. In addition, we argue that theories of spelling development need to pay more attention to the interactions among various sources of knowledge. For example, we suggest that children's tendency to make use of letter names is affected by the phonological structure of the letter names themselves. To exemplify these notions, let us begin by examining how children use their knowledge of letter names to guide their spellings. Letter Names and Spelling Middle-class North American children typically learn to recite the alphabet (often by singing the alphabet song) and to name many of the letters well before they begin formal schooling. Parents, children's television programs, and preschools are just some of the sources from which children acquire this information. In one study (Mason, 1980), almost two thirds of 4-year-olds were said by their parents to "very often" recite the alphabet without error. Over half of the children were said to recognize more than 20 letters of the alphabet by name. In another study, which assessed acquisition of alphabet skills directly rather than rely on parental report, children could recite or sing five or more letters of the alphabet by age 4 and were almost perfect by age 5 (Worden & Boettcher, 1990). Shown uppercase letters and asked to name them, 4-year-olds were correct on about 14 of the 26 letters. Five-year-olds were correct on about 22 letters. Children's knowledge of the sounds of letters was not as good as their knowledge of the names. Four-year-olds could provide the sounds for about 6 letters of the 26 and 5-year-olds for 8. Given that children enter school with a good deal of knowledge about letter names, what role, if any, does this knowledge play in learning to write and read? One might argue that letter-name knowledge cannot directly benefit spelling or reading because written letters symbolize phonemes and not the letters' names. After all, bat is pronounced /bæt/ rather than /biæti/. However, most English letter names contain the phoneme that is commonly represented by the letter. For instance, b has the name /bi/; this letter typically symbolizes the phoneme /b/, which is the first sound of its name. Durrell (1980), Ehri (1983, 1986), and others argued that letter-name knowledge plays an important role in the early acquisition of literacy. In fact, the theories of spelling development that we have discussed depict beginners as relying so heavily on a letter-name strategy that they spell a phoneme or sequence of phonemes that matches a letter name with the corresponding letter whenever it is possible to do so (Ehri, 1986; Gentry, 1982; Henderson, 1985). However, recent evidence suggests that such letter-name spellings may not be as widespread as previously thought. Children's tendency

to use letter names as a guide to spelling appears to be influenced by the phonological properties of the letter names themselves. Evidence to support this point comes from a series of experiments conducted by Treiman (1994). In the first experiment, first graders were asked to spell a series of monosyllables, each of which contained a sequence of phonemes that matched the name of an English consonant letter. Examples are /var/, which contains the name of the letter r, /vel/, which contains the name of the letter l, and /pem/ and /kef/, which contain the names of m and f. If children use a letter-name spelling strategy whenever it is possible to do so, as the theories of spelling development claim, they should spell these nonwords as VR, VL, PM, and KF. The first graders, who were tested in October and November, did make some of these consonant-consonant (CC) errors. However, the errors were by far most frequent for nonwords containing the name of r. For nonwords, such as /var/, 41% of the children's spellings were letter-name errors such as VR. The letter-name errors occurred less often for l, with a rate of 9% errors such as VL for /vel/. Vowel omissions in spellings of nonwords containing the names of m, n, f, and s were even less common, occurring between 2% and 4% of the time. It appears that some vowel-consonant (VC) letter-name sequences are more likely to be spelled as units than others. Treiman's (1994) second experiment was designed to investigate these differences further. In addition to examining letters with VC names, the second study also included letters with consonant-vowel (CV) names. Children in preschool, kindergarten, and the very beginning of first grade were tested; these children were screened to ensure that they knew the names of the critical letters. The children were asked to spell syllables containing phoneme sequences that matched the names of English letters. The letters considered were r, l, m, n, f, s, t, p, and k. For example, /gar/ contains the letter name for r, or /ar/, /zef/ contains the letter name for f, or /ef/, and /tib/ contains the letter name for t, or /ti/. The kindergartners and first graders produced most CC spellings for syllables containing the name of r. Indeed, kindergartners made errors such as GR for /gar/ 61% of the time, and first graders did so 50% of the time. Syllables containing the letter name l were the next most likely to be spelled as CCs, with 41% such errors for kindergartners and 19% for first graders. CC spellings were less common for syllables that contained the names of the letters m, n, f, s, t, p, and k. However, children did produce more CC spellings for these syllables than for control syllables that did not contain letter-name sequences. Thus, although the kindergartners' and first graders' spellings were most influenced by their knowledge of letter names for r and, to a lesser extent, l, there was some effect for a broad range of other letters. (The preschoolers showed a different pattern of performance than the older children; their results are discussed further on.)

Two additional experiments reported by Treiman (1994), as well as data on first graders' spellings of real words reported by Treiman (1993), provide further evidence that letter-name spellings are not equally likely for all consonants. These errors are most common for r, next most common for l, and less frequent for other consonant letters. These differences speak against the idea that children use a letter-name spelling strategy whenever it is possible to do so. Why are children more likely to spell /ar/ as r than to spell /el/ as l or /ti/ as t? The answer to this question, Treiman (1993, 1994) suggested, may lie in the phonological structure of the letters' names. In particular, some letter names may be easier for children to segment into phonemes than others. Children have particular difficulty dividing the sequence /ar/ into phonemes and so tend to spell this sequence as a single unit. The difficulty with /ar/ may reflect, in part, the special properties of postvocalic /r/. Evidence from speech errors and from the learning of games that divide spoken syllables in various ways suggests that a vowel and a following /r/ form an especially tight bond, stronger than that between a vowel and a following /l/ or between a vowel and another following consonant (Derwing & Nearey, 1991; Laubstein, 1987; but see Stemberger, 1983). Thus, based on the properties of the consonants in the VC letter names, the letter-name sequence /ar/ may be more cohesive than /el/. Both of these in turn may be more cohesive than sequences such as /es/ (Derwing & Nearey, 1991; Hindson & Byrne, 1997; Treiman, 1984; Treiman, Zukowski, & Richmond-Welty, 1995). A child attempting to spell the spoken syllable /gar/ may analyze it into /g/ and /ar/ and, being unable to segment the /ar/ further, may spell the syllable as GR. So far, we have focused on the special properties of postvocalic /r/ that may make it hard for children to divide the letter name /ar/ into phonemes. However, the nature of the vowel may be important as well. The letter r is unusual in that the vowel phoneme in its name, /a/, occurs in no other English letter name. The lack of letter names such as /ap/ or /ag/ leaves children without a mate to compare with /ar/. In contrast, the repetition of vowel phonemes across other consonant letter names may help children to understand that the letters are used to represent the distinctive consonant phonemes rather than the repeated vowels. Thus, a child may come to realize that the letter names /bi/, /di/, /pi/, /ti/, and so on, share the vowel /i/ and that the letters b, d, p, and t symbolize the consonants that distinguish these letter names. The same may be true for the VC letter names /el/, /ef/, /em/, /en/, and /es/. How much of a contribution the uniqueness of the vowel in /ar/ among the letter names of English makes to children's use of r letter-name spellings remains to be investigated. We have seen that first graders and kindergartners sometimes symbolize a difficult-to-segment sequence such as /ar/ or /el/ with the letter that has

this name, producing errors such as CR for car and HLP for help. Additional evidence points to letter-name effects in even younger children. Consider the results for the preschoolers in the second experiment by Treiman (1994), in which children attempted to spell syllables such as /gar/, /zef/ and /tib/. A number of the preschoolers originally screened did not know the names of all of the critical consonant letters and so did not participate in the spelling test. Those who knew the letter names, however, made some intriguing errors. Unlike the kindergartners and first graders, these preschoolers produced many singleletter spellings. The single letter that they used was often the consonant letter suggested by the letter-name sequence in the spoken syllable. For example, the preschoolers often spelled /gar/ as R, /zef/ as F, and /tib/ as T. These errors are interesting because children generally have more success spelling initial consonants than final ones (Stage & Wagner, 1992; Treiman, 1993; Treiman, Berch, & Weatherston, 1993). Letter-name knowledge is apparently potent enough to override this tendency, making preschoolers more likely to spell /gar/ as R, the final letter, than as G, the initial letter. Thus, children who have a strong knowledge of letter names before they begin formal schooling may be able to take advantage of this knowledge to produce sound-based spellings. A child who spells /gar/ as R is demonstrating a knowledge that the spelling of a word is not arbitrary that the letters in a spelling have some connection to a word's sound. A child may be able to spell /gar/ as R based on the overall similarity in sound between /gar/ and /ar/; the child need not be able to divide the spoken syllable /gar/ into smaller units of sound (see Treiman & Breaux, 1982). Although spellings like R for /gar/ appear very primitive, the children who produce these spellings may be able to appreciate that certain aspects of conventional spelling, such as the r in car or the p in pizza, make sense given the sounds in words. In this way, letter-name knowledge may help children take their first steps toward understanding that writing is connected to speech. The names of letters may also help children to discover and remember the sounds that letters make, at least for those letters whose names suggest their sounds. Evidence to support this claim comes from a study by Treiman, Weatherston, and Berch (1994, Exp. 2). These researchers asked preschoolers and kindergartners to supply the first letters of syllables such as /ba/, /la/, and /ga/ and, in another condition, the last letters of syllables such as /ab/, /al/, and /ag/. Children were simply asked to say the first or last letters of the spoken syllables; they were not asked to write them. Knowledge of letter names could help children to remember the link between /b/ and b and the link between /l/ and l. This is because /b/ is found in the name of b and /l/ is found in the name of l. Letter names could not help children with the mapping between /g/ and g because the name of the letter g does not contain the phoneme /g/. Children indeed performed better in the supply-the-first-
< previous page

next page >

page_69
next page > Page 69
letter task on syllables for which letter-name knowledge could help them (e.g., /ba/, /la/) than on syllables for which letter-name knowledge would be useless or even misleading (e.g., /ga/). Similarly, performance in the supply-the-last-letter task was better for syllables such as /ab/ and /al/ than for syllables such as /ag/. An additional finding is that performance was better with letters like b, where the phoneme that the letter symbolizes is at the beginning of a CV letter name, than with letters like l, where the phoneme that the letter symbolizes is at the end of a VC letter name. This difference may arise because /b/ is in the salient onset position of the CV letter name /bi/. Children's ability to divide the letter name into its onset and rime (Bowey & Francis, 1991; Kirtley, Bryant, Maclean, & Bradley, 1989; Treiman, 1985, 1992) helps them access the /b/ in the syllable /bi/. In contrast, the /l/ of /el/ is in a less salient position in the spoken syllable and is more difficult to separate from the vowel. Thus, the phonological properties of a letter's name that make it easier or harder to segment into phonemes seem to have at least two effects. First, these properties influence children's tendency to use the letter to spell the sequence of phonemes in its name. Second, they affect children's ability to use the letter's name as a clue to its sound. As an example, the name of b, /bi/, is relatively easy for children to divide into phonemes. Its segmentability means that errors like BT for beat will be uncommon but that children will be able to use b's name to remember its sound. The name of /l/, /el/, is harder to break apart. Hence, children will make a fair number of errors like BL for bell and will have more trouble using the letter's name as a clue to its sound. Children's tendency to use letter names to discover the letters' sounds sometimes leads them astray. Consider the letter w, which is used in English to spell the phoneme /w/. However, the name of w ("doubleyou") does not contain /w/. The letter name that contains the /w/ phoneme is instead the name of y, /wai/. Not surprisingly, the kindergartners tested by Treiman, Weatherston, and Berch (1994) sometimes said that y makes the sound /we */. Also, they sometimes misspelled words with initial /w/ with y, as in YAT for wet or YRM for warm. These errors were nearly absent by the spring of first grade (see also Read, 1975; Treiman, 1993). Thus, young children who can divide spoken syllables into onsets and rimes may analyze the CV name of y into /w/ and /ai/. They may conclude that y should be used to spell /w/ just as other letters with CV names, such as b and k, are used to spell the first phonemes of their names. As children learn the spellings of common words such as went and will, in which /w/ is spelled with w, or as they are taught that w makes the sound /w/, they abandon their early belief that y corresponds to /w/. Exposure to print may thus be one factor that leads to the eventual disappearance of errors such as YAT for wet and CR for car. Children see

that words beginning with /w/ generally start with w rather than y. They observe that printed words almost always contain a vowel. Indeed, first graders' knowledge that printed words must include vowels leads them to sometimes produce spellings such as GRE for the nonword /gar/ (Treiman, 1994). A child's belief that /ar/ is an indivisible phonological unit suggests that the rime be spelled with single r; the child's orthographic knowledge suggests that the word contain a vowel. The child may solve this conflict by placing an e, which occurs as a "silent" letter at the ends of words such as came and give, at the end of the spelling. Thus, even in the early stages of spelling development, children may notice what words look like and may use this information when constructing their own spellings. In the next section, we focus more directly on children's orthographic knowledge. Orthographic Knowledge By orthographic knowledge, we mean children's understanding of the conventions used in the writing system of their language. Proficient writers possess a good deal of information about the orthography, including knowledge about the spacing of words, the orientation of writing, acceptable and unacceptable letter sequences, and the variety of ways in which certain phonemes may be represented, depending on such factors as their position in a word. It is widely held that individuals develop orthographic knowledge based on their experiences with the printed language. This knowledge, in addition to phonology, then influences spelling. The theories of spelling development we have described (Ehri, 1986; Gentry, 1982; Henderson, 1985) maintain that orthographic knowledge does not begin to affect a child's spelling until the child has accumulated a considerable number of words that are recognized by sight. These theorists describe orthographic knowledge as the learning of complex sequences such as the -ight of words such as light and learning when to double consonants in polysyllabic words. Very likely, knowledge of complex orthographic patterns such as these does develop late relative to other spelling skills. However, the theories fail to account for the possibility that young children possess knowledge about simpler conventions of the orthography. Treiman (1993) examined early spellings for evidence of adherence to relatively simple orthographic conventions. She looked at the writings produced over the course of the school year by first graders. These first graders were in a curriculum in which they were encouraged to write but their spelling was not corrected. The children tended to produce spellings that were consistent with the regularities of the English writing system. For instance, vowels and consonants that are more likely to occur as doublets in English, such as e and l, were more likely to occur as doublets in the

children's writing than letters that infrequently or never double, such as u and h. Another example of children's adherence to orthographic patterns involves ck. The ck spelling never occurs at the beginning of a word in written English; initial /k/ is instead spelled with c or k. The children in Treiman's study did use ck but rarely at the beginning of a word. These and other examples suggest that beginning spellers develop a sensitivity to simple orthographic patterns earlier than expected given current models of spelling development. Treiman's (1993) evidence of orthographic knowledge came from the writings that first graders produced as part of their everyday classwork. Treiman also experimentally investigated children's knowledge of orthography by devising an orthographic constraints test. This test included 16 pairs of nonwords. Each pair tested a constraint or regularity of the English writing system. One nonword in a pair conformed to the regular pattern; the other word did not. However, both nonwords were pronounceable. For example, one pair was ckun and nuck. Children were to choose which item looked more like a real word. If children make their judgments on the basis of sound only, both items would be equally likely to be chosen. However, if children consider orthographic acceptability in making their judgments, the item that conformed to the orthographic constraint should be chosen more often. Treiman found that middle-class kindergartners (tested in May), first graders (tested in March), and second graders (tested in May) all chose the conforming item significantly more than 50% of the time. The percentages of correct responses were 56% for kindergartners, 62% for first graders, and 83% for second graders. The above-chance performance of kindergartners and first graders supports the idea that knowledge of orthography begins to emerge earlier than previously thought. Treiman's (1993) orthographic constraints test contained 16 pairs of nonwords testing a variety of different constraints. Knowledge of no one constraint was explored in detail. Some further studies, however, specifically investigated children's knowledge of double consonants and vowels (Cassar & Treiman, in press). The first study focused on consonants. In English, consonant doublets may occur in the middle or at the end of a word but not at the beginning. In addition, medial doublets normally follow short vowels in polysyllabic words, as in latter. Single consonants normally follow long vowels, as in later. Pairs of nonwords were designed to test children's knowledge of these conventions. In pairs that tested knowledge of position, one nonword contained an initial doublet and the other nonword contained a final doublet. An example is nnus and nuss. If children know where consonant doublets may occur, they should judge that nuss is more likely to be a word than nnus. In pairs that examined the phonetic environment for doubling, one nonword contained a medial single consonant, as in salip, and the other contained a medial doublet, as in sallip. Cassar and Treiman asked

whether participants listening to pronunciations for the nonwords chose salip for a pronunciation with ''long a'' or /e/ in the first syllable and sallip for a pronunciation with "short a" or /æ/. The participants in Cassar and Treiman's (in press) first study were children in kindergarten, first, second, third, sixth, and ninth grades as well as college undergraduates. One group at each grade level was assigned to an auditory condition in which they chose which spelling looked best for the word they heard. The other group was assigned to a visual condition in which they viewed pairs of spellings and chose the one they thought looked more like a real word. For the pairs that tested knowledge of position (e.g., nuss and nnus), even kindergartners tested in the first semester of the school year picked the final doublet spellings significantly more often than chance. Not until sixth grade and above did children evidence knowledge of the correspondence between short vowels and spellings with medial doublets. That is, only the older children were able to reliably choose sallip for the pronunciation /s'ælip/ and salip for the pronunciation /s'elip/. These latter results agree with Henderson's (1985) claim that knowledge about the complex pattern of short vowel plus double consonant in two-syllable words develops later than the first few years of elementary school. However, young children's above-chance performance on the test of knowledge about the positions of consonant doublets suggests that some types of orthographic knowledge emerge much earlier in the course of spelling acquisition. This finding fits with Treiman's (1993) observation that the first graders in her study did not often make errors such as BBAL for ball. It appears that beginning spellers not only represent speech sounds when they write but that they also attempt to honor the kinds of letter sequences to which they have been exposed. Cassar and Treiman's (in press) second study further investigated children's knowledge of double consonants as well as double vowels. An attempt was also made to identify the spelling development of each child in terms of the stages outlined in the theories of spelling development. An examination of children's knowledge of doublets in relation to their level of spelling development was expected to yield insights into the types of information that children use when they are beginning to spell. As in the first study, an orthographic choice test employed pairs of nonwords. One nonword in each pair contained an acceptable vowel or consonant doublet; the other nonword contained an unacceptable doublet. The doublets occurred in the medial or final positions of the spellings, both of which are acceptable for doublets. Sample pairs are noss and novv and geed and gaad. If children know which letters are allowed to double, they should choose noss and geed as more word-like than novv and gaad. To identify each child's level of spelling development, the child was asked to spell a list of common words such as farm and people. The spellings were

scored on the basis of features thought to predominate at particular stages of spelling development. Beginning spellers considered to be at the semiphonetic and phonetic stages as described by Ehri (1986) and Gentry (1982), which correspond to the letter-name stage of Henderson (1985), were targeted in this study. According to the theories, these children focus only on sounds or phonetic mappings when they spell. Kindergarten, first- and second-grade children were tested during February. First and second graders, but not kindergartners, chose spellings containing allowable doublets over spellings containing unallowable doublets. That is, they judged that noss and geed were more like real English words than novv and gaad. Importantly, children classified as phonetic spellers performed significantly better than chance on the orthographic choice test. Children at the semiphonetic level did not show above-chance levels of performance. These results suggest that children begin to learn about which letters may double in English earlier than previously thought. Gentry (1982) claimed that during the phonetic stage, letters are assigned strictly on the basis of sound, without regard for the conventions of English orthography. The results of Cassar and Treiman's (in press) study dispute this claim by showing that children whose spellings have many of the hallmarks of the phonetic or letter-name stage possess some knowledge of orthographic conventions. Children may begin to learn what words look like earlier than commonly believed. They use this knowledge, together with their knowledge of phonology and letter names, to construct spellings. Morphological Knowledge The theories of spelling development we have reviewed depict the use of morphology to guide spelling as a late development. In fact, Henderson (1985) advised teachers that children need to be taught about the morphological relations among words. The relations to which Henderson referred are those such as the relation between courage and courageous. These connections may not be obvious to children, and so it may be best to point them out. However, not all morphological relations are this complex. Some, such as the relations between rain and rained or bar and bars, are simpler. Children can handle these kinds of morphological alternations in their speech from an early age (Berko, 1958). Hence, young children might take advantage of such relations in their spelling as well. Consider the verb wait. By adding the suffix -ed, we create the past tense form waited. The addition of -ed also changes the pronunciation of the /t/ to a flap, a quick tap of the tongue against the top of the mouth. The flap of waited, which is voiced, is similar to /d/, which is also voiced. If young spellers use only sound-based information, they should spell the flap of waited with a d. However, if children understand the relation in meaning
< previous page

next page >
< previous page
page_74
next page > Page 74
between wait and waited, and if they realize that this relation is marked in spelling, they should use a t in waited based on the spelling of the stem. This was the reasoning behind two studies conducted by Treiman, Cassar, and Zukowski (1994). The first study to be discussed (Treiman, Cassar, & Zukowski, 1994, Exp. 3) examined children's spellings of words containing flaps that were conventionally spelled with either t or d. The words contained either one or two morphemes. For instance, duty and attic are one-morpheme words with t flaps, and waited and dirty are two-morpheme words with t flaps. Sturdy and louder are examples of one- and two-morpheme words containing flaps that are conventionally spelled with d. If children use meaning relations among words to aid their spelling, they should do better on the flaps of the two-morpheme words (for which the stems can help them) than on the flaps of the one-morpheme words (for which there are no embedded morphemes that can aid performance). The results for first and second graders confirmed this hypothesis. These children were more likely to use t for two-morpheme words such as dirty than for one-morpheme words such as duty. The first graders, especially, often misspelled the flaps of both types of words as d, pointing to an influence of sound on spelling. However, the children were less likely to make this error for words like dirty than for words like duty. Children did not use morphological information to the full extent possible. Whereas they almost never misspelled the t of dirt with d, they sometimes misspelled the t of dirty in this manner. There is room for improvement in children's use of morphological relations among words to guide their spelling, but this strategy is by no means beyond their capabilities. The youngest children in the study just described (Treiman, Cassar, & Zukowski, 1994, Exp. 3) were second-semester first graders. Another study (Treiman, Cassar, & Zukowski, 1994, Exp. 4) was designed to explore whether even younger children can also benefit from meaning relations when spelling. Kindergarten, first-, and second-grade children were tested twice during the school year, once in the fall and then again in the spring. As before, the stimuli included words with medial flaps that were conventionally spelled with either t or d. Of the words containing each type of flap, half contained a single morpheme and the other half contained two morphemes. Instead of spelling the whole words, as in the preceding study, children were asked to fill in the missing t or d in each word's spelling. If young children's spelling is based only on sound, as the theories suggest, then children should spell the flaps of both one- and two-morpheme words with d. However, if children use morphology to supplement their performance, then they should perform better on the two-morpheme words than the one-morpheme words. This is what Treiman, Cassar, and Zukowski (1994, Exp. 4) found. Overall, children did better on d flap words than t flap words. Because flaps, being voiced, are closer in sound to /d/ than to /t/,

next page >
< previous page
page_75
next page > Page 75
children tend to spell them with d. This leads to correct responses for d flap words but incorrect responses for t flap words. Importantly, the kindergartners and first graders performed significantly better on the flaps of the two-morpheme words than those of the one-morpheme words. (The second graders did not show a significant difference, probably due to their relatively high overall levels of performance.) Evidently, the children used their knowledge of the spellings of the stems to help spell the flaps in the two-morpheme words. For instance, the link in meaning between float and floated suggested to children that the flap of floated should be spelled with a t. Children were less likely to use a t in floated than in float, showing that they did not use morphological information to the full extent of their ability. Nevertheless, these kindergartners and first graders could use meaning relations to guide their spelling even when so doing meant overriding sound. Together, the results of the two studies with flaps (Treiman, Cassar, & Zukowski, 1994, Exps. 3 and 4) indicate that children as young as kindergarten age have some ability to use simple morphological relations among words to guide their spelling. This result speaks against the view that the use of morphological information in spelling is a late development. To determine whether children are affected by morphology more generally, Treiman and Cassar (1996) turned to the case of final consonant clusters. Children sometimes fail to spell the first consonants of final clusters, especially when these consonants are liquids (/r/ or /l/) or nasals (/m/, /n/, or /h/) (Marcel, 1980; Read, 1975; Treiman, 1993; Treiman, Zukowski, & Richmond-Welty, 1995). For instance, first graders may spell horse as HOS or the nonword /vLnt/ as VUT. If children have trouble including the n in onemorpheme words such as brand, they should also have problems with the n in two-morpheme words such as rained unless they use their knowledge of the stem, rain, to aid them. However, if children are able to use morphology, they should omit the first consonant of a final cluster less often in two-morpheme words than in one-morpheme words. Thus, the underlying logic of the experiments with final clusters was the same as in the flap studies described earlier. The children in the experiments by Treiman and Cassar (1996) were asked to spell words with final consonant clusters, including one-morpheme words such as brand and two-morpheme words such as rained. The one- and two-morpheme words had the same final clusters in their spoken forms; for instance, brand and rained both end with /nd/. About a week after spelling the one- and two-morpheme words, the children were asked to spell the stems of the two-morpheme words (e.g., rain). The children's spellings of final cluster words were scored according to how they represented the final consonants. An A spelling was one that contained a reasonable representation of the first consonant in the cluster but not of the second consonant, as in RAN for rained. A B spelling represented only the second consonant, as in BRAD for brand. AB spellings symbolized both consonants in the final clus-

ter, as in RAND for rained. Given previous findings that children sometimes fail to spell the first consonants of final clusters, we expected to see a fair number of B spellings and fewer A spellings for the final cluster words. We asked whether B spellings would be less common for two-morpheme words than for one-morpheme words, suggesting that children benefited from the additional meaning information in the two-morpheme words. In the first study by Treiman and Cassar (1996), children in first, second, and fourth grades were tested in March. Overall, children were more likely to omit the first consonant of a final cluster (B errors) than the second consonant of a final cluster (A errors). However, B errors were less frequent for two-morpheme words such as rained than for one-morpheme words such as brand. That is, children were less likely to spell rained as RAD than to spell brand as BRAD. Children apparently benefited from the stem rain when spelling the two-morpheme word rained. However, the first and second graders did not use their knowledge of the stem to the full extent possible because they left out the n of rained more often than the n of rain. Errors in which the final consonant of the cluster was omitted, or A errors, were more common for two-morpheme words than for onemorpheme words. That is, children misspelled rained as RAN more often than they misspelled brand as BRAN. In assembling the spelling of a two-morpheme word from the spellings of the component morphemes, children sometimes seemed to forget the second morpheme. Our second study (Treiman & Cassar, 1996) included children in kindergarten as well as first grade. The kindergartners were tested once, late in the school year. The first graders were tested both in the fall and the spring. The children were asked to complete each word's spelling. For instance, bra ___ was printed on the test sheet and the children were told to finish this spelling for the word brand. As in the first study, omissions of the first consonant of the final cluster (B errors) were more common for one-morpheme words such as brand than for two-morpheme words such as rained. That children were more likely to omit the n of brand than the n of rained suggests that they derived some benefit from the stem rain. In contrast, omissions of the second consonant of the final cluster (A errors) were more common on two-morpheme words than on one-morpheme words. Children sometimes spelled rained without a final d, suggesting that they stopped writing after they had symbolized the first morpheme. The results of the experiments with flaps and final clusters indicate that children's spelling can be influenced by morphology from an early age. This conclusion is different from that drawn by Treiman (1993) based on her naturalistic study of first graders' classroom writings. In that study, first graders' spellings were seemingly unaffected by morphology. For example, the children in Treiman's naturalistic study were not significantly more likely to include the n in a two-morpheme word such as rained than in a one-mor-

pheme word such as brand. The different results in the two studies might reflect task differences. In Treiman's naturalistic study, children wrote words as part of texts that they produced during the classroom writing period. In the experiments described so far, children spelled or completed spellings for isolated words presented by an experimenter. Hoping that the different findings might be related to these task differences, we designed a third study using the same two-morpheme and one-morpheme words with final clusters. Treiman and Cassar's (1996) third study included two groups of first-semester second graders. One group of children spelled the words using a whole word spelling task. The other group of children was asked to compose a sentence using each word and then to write out the entire sentence. If composing a sentence is more like the writing task in the Treiman (1993) study, then children in the sentence condition should produce similar types of spellings for the final consonant clusters in one- and twomorpheme words. However, this did not turn out to be the case. The children in the sentence condition, like those in the word condition, showed different patterns of performance on the one-morpheme and two-morpheme words. Omissions of the first consonant of the final cluster (B errors) were more common on one-morpheme words than two-morpheme words, and omissions of the second consonant of the cluster (A errors) were more common on two-morpheme words. There are several plausible explanations for the failure of the sentence condition to replicate the results of Treiman (1993). The most obvious is that the sentence task did not duplicate the conditions of the naturalistic setting. In the experiment, the children were required to use a particular word to compose a complete idea. In the classroom, children wrote their ideas without restrictions as to word usage. In this situation, words may become part of the meaning of the message without having to be individually analyzed in terms of meaning. In contrast, a child who is required to use a specified word in a sentence may need to analyze the word's meaning to determine how it should be used. This may promote morphological analysis of the twomorpheme words. Of course, this explanation is conjecture without more evidence. The most striking and important finding from Treiman and Cassar's (1996) third experiment, as well as from the other experiments on flaps and final clusters, is that young children have some ability to use morphological strategies in spelling. In this way, children avoid errors that they would otherwise make if they were bound solely to a phonological spelling strategy. Conclusions Existing theories of spelling development (Ehri, 1986; Gentry, 1982; Henderson, 1985) portray children as passing through a series of qualitatively different stages as they learn to spell. During an early period, children are
< previous page

said to treat writing as a task of symbolizing the sounds in words. They progress through each word from left to right, using their knowledge of phoneme grapheme correspondences and of letter names to represent the word's sounds. Only later, according to the theories, do children begin to symbolize a sound differently depending on its position or its context. Only later do children use morphological relations, symbolizing meaningful words instead of sounds. The results that we have reviewed suggest that these views of spelling development are too limited. There is no doubt that young spellers rely on sound to a large degree, but this is not all that they do. For example, children often spell flaps as d, testifying to the importance of sound. However, children's knowledge of the relation in meaning between dirty and dirt makes them less likely to misspell the flap of dirty with a d than to misspell the flap of duty with a d. Children have some ability to divide dirty into dirt and -y, some notion that spelling represents meaning as well as sound. This is a long way from being able to retain the spelling of courage in courageous, but it is a start in that direction. Along with their attention to meaning, young children also attend to the kinds of letter sequences that make up words. Early on, they notice that English words may start but not end with capital letters and that words may end but not start with double consonants. They notice that letters such as e and s may double but that letters such as a and v rarely do. Children attempt to reproduce what they have observed, so even first graders do not usually produce such errors as BBAL for ball or HAAT for hat. In our view, spelling involves an interaction among different sources of knowledge from the beginning. Although sound plays a central role in early spelling, young children also have other kinds of knowledge, including knowledge of morphological relations among words and information about the kinds of letter sequences that typically occur in print. Theories that treat learning to spell in terms of a sequence of stages that involve qualitatively different types of information are too simple. We must acknowledge that spellers, even young ones, are able to use various types of knowledge. We must learn more about how these different sources of information interact.

Chapter 5 How Learning to Spell German Differs from Learning to Spell English Heinz Wimmer Karin Landerl University of Salzburg Psychological research on the acquisition of spelling is quite anglo-centric due to the simple fact that the majority of findings come from children who learn to spell English. The present study questions some of the English conclusions by contrasting them with German findings. German offers an interesting test case for conclusions about the role of orthographic consistency and of phonology in the development of spelling because, due to the partly common roots of German and English, there are similarities with respect to phonology, although German is written in a more consistent manner than English. The consistency with which phonemes map onto graphemes is of obvious importance for spelling both within and between writing systems. For example, Treiman (1993), in her landmark study on early spelling, concluded from the regularity effect observed in the spellings of her first-grade sample "that a writing system with one-to-one relations from phonemes to graphemes would be easier for children to learn than a writing system with one-to-many relations from phonemes to graphemes" (p. 59). German is certainly not a writing system with one-to-one relations from phonemes to graphemes. For nearly every phoneme there are at least two possible spellings. For example, /a:/ can be spelled as a, aa, and ah, and for /b/, as for most other consonants, possible spellings are b and bb. However, doubling of consonant letters only occurs after short vowels (e.g., Sommer [summer], Butter [butter]), and most of the different spellings for vowels have to do

only with vowel length. Another inconsistency is that / / is spelled with sch and with s. However, the use of s for / restricted to cases of / / before /t/ and /p/, as in stehen (stand) or Sport (sport).
/ is
One obvious difference between English and German is that the latter makes little use of silent letters. For example, in words such as Knie (knee) the k, in contrast to English, is not silent and, similarly, the final -e in words such as Nase (nose) or Liebe (love) is pronounced. However, the main difference between German and English lies in the consistency of vowel spelling. Identical spellings of different vowels such as in sign - signature or heal - health hardly exist in German, but, as already noted, there are different spellings for the same phoneme, for example, for the /a:/ in Zahl versus in Saal or for the / / in Bälle versus in Welle. The diacritical marker in the case of Bälle (balls) indicates vowel change due to pluralization while preserving morpheme identity (e.g., Ball - Bälle, Ofen - Ofen). Even this comparatively moderate way to preserve morpheme identity creates spelling problems as it has the effect that there are two possible graphemes (ä and e) for / /. Furthermore, vowel graphemes with diacritical markers are not only used to preserve morpheme identity. In Bär (bear), for example, the ä is not due to a morphological process. However, despite these ambiguities with which vowels are represented in the German writing system, the difference from English is massive. Most often, there are only two possible ways to represent a vowel and, in addition, the use of phonological and morphological constraints often reduces the possibilities to one. Study 1 explores the effect of these differences between the German and the English writing systems with respect to vowel representation. For this comparison, we used words with similar pronunciation and with similar spelling in the two orthographies (e.g., rose - Rose, friend - Freund). Expectations are that German children should produce an incorrect vowel spelling only if phoneme-grapheme correspondences are ambigous and that the error should consist of the alternative spelling possibility. For English children, it was expected that the overall inconsistency of the phoneme-grapheme relations for vowels may lead to general uncertainty about how to spell vowel sounds. Besides phoneme-grapheme inconsistency, Treiman (1993) identified phonological aspects of spoken English as causing spelling problems: ''Not all of children's difficulties in learning to spell stem from the nature of our writing system. In addition to the problematic aspects of the English writing system its one-to-many relations from phonemes to graphemes, its use of multiple-letter graphemes, and its tendency to spell morphemes consistently despite changes in their phonemic forms the nature of spoken English also contributes to children's difficulties'' (p. 59). She concluded that "beginning spellers would have less difficulty, at least in the sense of producing fewer illegal errors, in languages whose spoken forms contain few or no consonant

clusters" (p. 60). The difficulty of consonant clusters according to Treiman's analysis has to do with the fact that spelling clusters requires phonemic segmentation of the cluster, which is difficult because the cluster is treated as a phonological unit, namely, as syllable onset or as coda of the rime. German provides a test case for this conclusion because, similar to English, German has many words with consonant clusters (e.g., blau - blue, drei - three, Hand - hand, Wolf - wolf), and one should, therefore, expect that German children should have similar difficulties with the spelling of consonant clusters as English children. However, the other possibility is that the higher consistency of the German writing system may also affect children's ability to spell consonant clusters. This effect of consistency of cluster spelling is expected to operate indirectly via reading acquisition. In other studies with German first graders, it was found that the high consistency of German's grapheme phoneme relations in conjunction with the common phonics instructional approach makes acquisition of grapheme-phoneme recoding as a reliable word recognition strategy easy (Wimmer & Goswami, 1994; Wimmer & Hummer, 1990). For spelling acquisition, it is relevant that word recognition via grapheme-phoneme recoding provides systematic segmentation training. For example, recoding of blau as /b/-/l/-/ao/ and subsequent recognition as the spoken word "blau" makes prevalent the phonemic segments of the consonantal onset cluster. The expectation is that German children may have little difficulty with spelling consonant clusters because of their reliance on recoding as an early word-recognition strategy. Study 2 examines these differing expectations for consonant cluster spelling among German children and also provides information on several other aspects of spelling development among German children. Before presenting the two studies, some information on the instructional approach experienced by the German children participating in these studies may be useful. Due to the fact that there is no reading preparation in kindergarten, our children begin school often with very limited letter knowledge, with no reading ability and, often, with no phonemic awareness at all (Wimmer, Landerl, Linortner, & Hummer, 1991). In Grade 1, children are then exposed to a slowly proceeding, phonics-based instructional approach, where letter sounds, instead of the conventional letter names, are learned. For example, for the letter f, children learn /f/ and not /ef/ or /fe */, and, similarly, for m, they learn /m/ and not /em/ or /me */. For the letters representing stop consonants, the letter sound is the stop plus a schwa sound, for example, /pe */ for p. The first letters children learn are for vowels and continuants to make word recognition via sounding out and blending easier to demonstrate and to practice with words such as Mama, Oma, im, am. The multiletter graphemes (sch, ch, au, eu, äu, ei) are introduced in the same way as single letters, and graphic markers are used to signal multiletter graphemes in

words. Graphic markers are also used for syllable boundaries to make blending easier. In the beginning, children are induced to utter their blending attempts as word preforms that allow the teacher to help and to correct. The word preforms quite often have artificially lengthened phonemes and wrong stress assignments, but due to the consistency of German orthography, they are normally close enough to the target pronunciation to allow recognition. In first grade, there is more emphasis on reading than on spelling. Children normally spell words and sentences that they have already read. Invented spelling of new words is not encouraged, and misspellings are always corrected. Study I: Vowel Spelling by German and English Children This exploration of German-English differences in children's spellings of vowel sounds was an addition to a reading study that focused on orthography effects on reading in the first years in school. To minimize memory and attentional problems involved in phonemic analysis and in letter production, the children's task was to simply insert the missing letters for the vowels in given skeleton spellings. A main methodological feature of the study was that words with similar pronunciations and spellings and with identical meanings in the two languages/orthographies were used (e.g., Nase - nose, Boot - boat, Preis - prize). From the identical meanings in the two languages, it follows that the frequency with which these spellings were encountered by German and English children should not be too different. From the similarity of the words, with respect to phonology and with respect to number and kinds of letters, it follows that phonemic analysis and letter production should not account for systematic spelling differences between German and English children. Eighty-two English and 87 German children participated with about equal numbers of children from Grades 2, 3, and 4. The English children had about half a year more of school experience than the German children because testing took place at the end of the school year in London and around the middle of the year in Salzburg. At least for the younger children, it can be expected that they may not have learned the conventional spellings to a major extent and, therefore, their spellings may be affected by the difference between German and English in the consistency with which vowels map onto graphemes. The spelling task was performed in class. Each child received a sheet with 29 skeleton spellings from which the letter(s) for the main vowel was missing (e.g., gr_n for green). The experimenter first pronounced each word, then read a sentence that included the word in order to specify the meaning,

then repeated the word once again. For example, "green The grass is green green." After this, children had to insert the missing letter(s) for the vowel into the skeleton spelling. The first 5 items were used to explain and practice the task, leaving 24 test items. Table 5.1 shows the English and the corresponding German test words. The italicized letters were missing in the skeleton spelling. As evident, the final -e was provided in both the English and German spellings. Table 5.1 also shows that, in the case of heart - Herz and pearl - Perle, the r was deleted together with the vowel grapheme. This was not done in the case of bear Bar to avoid the situation in which only the first letter would have formed the skeleton spelling. Differences in how English and German children spelled the vowel of each item pair are presented in Table 5.1. From percent correct in Table 5.1, it is TABLE 5.1 English and German Vowel Spellings Percent Correct Number of Examples of Misspellingsb Different Spellingsa Item English German English German English German rose-Rose 98 100 3 1 ai-e ghost-Geist 95 99 4 2 a-e-s eu home-Heim 94 99 4 2 u-e-a nose-Nase 93 100 6 1 e-h-a-r-p stone-Stein 90 99 8 2 a-r-w-p-l-oa if whale-Wal 87 91 8 4 e-i-o-g-r-u ah(5)-aa-o 85 97 8 3 a-n-e-u-f-i oh-n throne-Thron green-grun 84 94 11 4 e(5)-er-ne-ea-r-ln-ie-et u-ö-an prize-Preis 82 100 9 1 u-s-ii-z-a-t-y-e slime-Schleim 79 95 7 2 e(5)-u(5)-a-r-m-l e wasp-Wespe 74 99 6 2 o(16)-e-b-t-p ä deep-tief 72 89 14 2 e(7)-ea(5)-er-iep-pe-o i(10) bear-Bär 71 66 15 4 ae(5)-ee-eu-a-e-aa e(25)-ee-a boat-Boot 63 53 9 5 oo(10)-ou(8)-o(6)-ao-ea o(37)-u-a bread-Brot 60 99 15 2 e(7)-ae(5)-a-er-ee t nerve-Nerven 54 98 20 3 ur(8)-u(6)-ea-ar-oo-a e-err coal-Kohlen 50 45 17 4 oo(13)-o(11)-ou-oe-a o(46)-oo steel-Stahl 48 47 15 5 ea(13)-e(11)-i-ie-a-eu a(40)-aa-o friend-Freund 48 98 22 3 ei(8)-e(5)-i(5)-ea-ine-ae e-eu pearl-Perle 39 95 27 4 ea(10)-er(6)-ar-ru-ol-ur e-re-a heart-Herz 32 99 28 2 ar(18)-ea-aru-ur-r-ae-aer et soul-Seele 29 28 17 3 oa(21)-ol(9)-oo(8)-oe-o e(52)-eh(11) rhyme-Reim 26 97 8 3 i(41)-a(9)-e-m-o-r-miss eu-ein thief-Dieb 22 90 15 3 ei(20)-ee(15)-ea(11)-e(6)-i i(8)-ei aThe number of different spellings includes the correct spelling. bIn parentheses the number of children committing the misspelling is given if more than one child produced this spelling.

evident that for the English words, the difficulty of correct vowel spelling was rather graded, ranging from such easy words as rose and ghost, with over 90% correct, to such difficult ones as rhyme and thief, with less than 30% correct. In contrast, for the German words, spelling of the vowels was either very easy or rather difficult: for 19 words, the percentage of correct vowel spelling was about 90% and higher and, for only 5 words, percentages ranged from about 70% to about 30%. Overall, for 19 word pairs, the vowel was easier to spell for the German than for the English word, whereas for only 5 pairs, the opposite was the case. Why vowel spelling proved difficult for some of the German words is easy to understand from the misspellings listed in Table 5.1. In the case of Bär (only 66% correct), 25 children used e for /e/. The letter e actually is the more common spelling for /e/, and in the case of Bär, morphological considerations are of no help to decide between e and ä. In the case of the four other difficult words Boot, Kohlen, Stahl, and Seele it is obvious from the misspellings that children did not use the specific orthographic marking of the long vowel in these words. For example, in the case of Kohle, 46 children inserted the single o letter for the vowel. In the case of Seele, there were 52 children who spelled the /e:/ with the single e letter, and there were an additional number of children who marked vowel length explicitly with eh. Presumably, it was not a failure to recognize that the vowel is long in these words, which led to the incorrect spellings, but the inconsistency with which long vowels are orthographically marked. This orthographic interpretation of the difficulty of the spelling of long vowels is suggested by the observation that in the case of /i:/ in tief and Dieb, comparatively few children neglected the orthographic marking of the long vowel. The difference is that for /i:/, there is the specific grapheme ie named long-i that rather consistently represents /i:/ (exceptions are the pronouns ihr [her] and ihm [him]), whereas in the case of /a/, /e/, and /o/, the long version of the vowel can be represented by a single vowel letter, by a double vowel letter, and by the h after the vowel letter. The most impressive difference between how English and German children spelled the vowels of the corresponding word pairs is given by the number of different spellings in Table 5.1. In this number, the correct spelling is included together with the number of different misspellings. From Table 5.1, it is evident that for each word pair, the English children produced a higher number of different vowel spellings than the German children, and in several cases, the difference was large (e.g., for friend Freund: 22 different English, 3 different German vowel spellings). It is important to note that the orthography difference in the number of different vowel spellings is not simply due to the difference in the number of correct spellings. For five words (Bär, Boot, Kohlen, Stahl, Seele), the German children produced a higher number of incorrect spellings than the English children. Neverthe-

less, the number of different vowel spellings produced by the German children was small, even for these words, and ranged from 3 to 5, whereas for English children the number of different spellings for these words ranged from 9 to 16. The orthography difference in the variety of vowel spellings quite plausibly reflects the difference in the consistency with which vowels map onto letters in English versus German. Another indication of the uncertainty of what letters English children should use for vowels is the finding that in 32 cases (1.6% of all words), English children simply did not insert any letter at all in the skeleton spelling, whereas only 1 such case occurred among the German children. However, there were a number of misspellings produced by English children that can hardly be explained by uncertainty which letter(s) to use for a certain vowel. The main characteristic of these misspellings is that consonant letters with no relation to the pronunciation of the word were used. Therefore, it seems plausible that in these cases, the difficulty had to do with phonemic segmentation of the word pronunciation and/or with relating the segments to the letters of the skeleton spelling. Altogether there were 135 (7%) such vowel spellings with consonant letter(s) for the English but only 10 (0.5%) for the German words. The more plausible type of such consonant inclusion was that the child used the consonant letter given in the spelling skeleton after the blank together with a vowel letter. For example, in the case of pearl, the final l was used together with one or two vowel letters. The resulting spellings were poll, pell, parll or paell, and in the case of deep, this strategy led to depp and diepp. There were 50 such misspellings among the English but only 3 among the German spellings. Another error type was that no vowel letter was used at all but rather one or two consonant letters. For example, in the case of nose, the letters h, r, and p were inserted instead of a vowel letter, resulting in the spellings nhse, nrse, npse. There were 46 English misspellings of this strange type but only 2 German misspellings. Consonant letters were also used in conjunction with vowel letters. Examples are grern, grren, grnen, and gretn for green and prrikl, peteal, pulel, plurchl, pklul, pulul for pearl. Again, the phonological inappropriateness of the spellings is striking. It should be noted that for pearl, nerve, and heart, all occurrences of the letter r either singly or in combination with vowel letters were not counted as an inappropriate use of consonant letters. One could speculate that the reason for the phonologically inappropriate misspellings made by the English children may have less to do with lacking knowledge of phoneme-grapheme correspondences, and more to do with difficulties inherent in the specific form of our spelling task. To find out what letter(s) to insert into the skeleton spelling, the child has to examine the skeleton spelling, segment the phonological form of the given word into phonemes, relate the resulting phonemic segments to the letters given, figure out which segment is not represented and, finally, find the letter(s)

for the misssing vowel segment. It seems possible that the phonologically inappropriate spellings of the English children result from difficulties with the segmentation of the phonological word form or from difficulities with the matching of the segments to the letters given. Evidence for such matching difficulties are those errors of the English children in which they inserted the given consonant letter after the blank together with a vowel letter (e.g., diepp for deep). Of course, the question is why only the English children, but not the German children, had difficulties with phonemic segmentation or phoneme-to-letter matching. This question will be taken up again in the conclusion after Study 2, which shows that German children do not exhibit difficulties with the spelling of consonant clusters that also require segmentation. The argument is that early reliance on phonological recoding in word recognition allowed by high grapheme phoneme consistency and induced by phonics instruction provides German children with segmentation training that is responsible for the advantage German children have with respect to spelling. First, however, Study 2 presents more comprehensive data on the spelling performance of German children in the early phase of spelling acquisition. In contrast to Study 1, in which children had to insert vowel letters in skeleton spellings, the participants of Study 2 produced spellings for whole words. Specific questions were how consonant clusters were spelled and whether children show differences in the spelling of consonants versus vowels. Study 2: Spelling by German Children in Grade One This study is based on spellings collected for standardization of a classroom spelling test in Austrian schools. Three classes, totalling 68 children, participated at the end of Grade 1. These children had not more than about 9 months of reading and spelling instruction because in kindergarten, there is no reading preparation. Testing in the classrooms was not done by the teacher but by a collaborator who was specifically instructed not to pronounce the words in an exaggerated High German manner, which is closer to the correct spelling than standard Austrian High German. One difference is that in Southern German dialects and in Austrian High German, the stop consonants /b/, /p/, /d/, and /t/ are neutralized in most positions. For example, the stops of Paul and Ball and of Rad and Rat sound more or less the same, and, therefore, pronunciation is of little help in choosing the correct letters. Children had a test form with 25 sentences in front of them. The test word from each sentence was missing and had to be inserted by the child. The tester first pronounced the word, then read the sentence, then repeated the word, after which the children had to fill it in the blank. Table 5.2 shows the 25 test words ordered with respect to difficulty. In Table 5.2, first the

pronunciation of the word is given, followed by the correct spelling (and the English counterpart) and by percent correct, and, finally, all misspellings are listed. For misspellings that were produced by more than two children, the number of occurrences is added in parentheses. Correct capitalization is not considered. Table 5.2 shows that all the words were rather short not longer than two syllables or six graphemes and can be considered to be of high frequency in spoken language (as evident from the English counterparts). From the pronunciations, it is evident that several words include consonant clusters both in initial position and/or in end position. This allows examination of Treiman's (1993) conclusion that phonological difficulties affect beginning spellers independent of orthographic consistency. Furthermore, the words present a variety of orthographic problems as evident from the relations between pronunciation and correct spelling in Table 5.2 in nearly no case did the spelling follow unambiguously from the pronunciation. For example, several pronunciations end with /t/, but the spelling is d in Hund or Feld and t in Hut and Bett. Similarly, / / is spelled with sch in schwimmt and with s in steht, and the /e/ is represented with e in Feld and with ä in Mädchen. Consonant Clusters Table 5.2 shows that there were eight words with consonant clusters in word initial position (sparen, steht, streiten, schwimmt, schnell, Schnee, Klasse, trägt) and five words with consonant clusters at the end of the word (Wind, Hund, Feld, schwimmt, trägt). Not included in the end cluster words was arm, because here the r lengthens the vowel and is not pronounced. The words schwimmt and trägt have a special status because the end clusters result from the addition of a morphemic -t to the stem of the verb (i.e., schwimm + t) to form the grammatical inflection required by third person singular. Altogether, phonemically incorrect spellings of both onset and end clusters occurred extremely infrequently. For onset clusters, only four such misspellings were observed (0.9%). They occurred only for schwimmt (two cases), streiten, and trägt and always affected interior phonemes of the cluster. These phonemes were either omitted (four cases: e.g., schimt for schwimmt, schreiden for streiten) or misrepresented (one case: schfipt for schwimmt). The phonemically correct spellings of the onset clusters apparently were not due to the fact that children simply produced learned spellings for the cluster words from memory. As evident from the listed misspellings of these words in Table 5.2, each of these words was misspelled by a number of children and, quite often, the onset was orthographically misspelled: schbaren instead of sparen, schtreiten instead of streiten, and Snee instead of Schnee. In all these examples, however, the phonemes constituting the onset cluster are present. For end clusters, it was also the case that misspellings were extremely infrequent, with only seven (2%) misspellings. In four cases, the interior

page_91
next page > Page 91
consonant of the cluster was omitted (e.g., Hudd for Hund, trät for trägt) and in three cases, the final /t/ was omitted. All the final t omissions occurred for schwimmt and may not be due to a phonological problem. Because schwimmt has quite a number of letters, children may have forgotten the inflection represented by /t/ when they came to the end of the spelling. This interpretation is suggested by the finding that not a single omission of the final /t/ occurred for Hund, Wind, Feld, and trägt. Interesting spelling attempts for schwimmt were schfipt (m omitted) and sweimmnt (no end cluster error), where children apparently transcribed articulatory features: The /p/ sound results from opening the lips after the /m/ and the /n/ results from bringing the tongue after the /m/ in the alveolar position to articulate the following /t/. Again, it is important to note that the close-to-perfect performance for end cluster spellings cannot be due to the fact that children may have produced learned spellings of these words from memory. This is evident from the listed misspellings of the end cluster words in Table 5.2. For example, in the case of trägt, the majority of the spellings were orthographically incorrect, but only two phonemically incorrect. The near absence of difficulties with the spelling of consonant clusters was also observed for a group of 21 children who, at the end of Grade 2, were identified as suffering from specific spelling difficulties. These children (16 boys, 5 girls) were nominated by their teachers as showing unexpected spelling difficulties. Additional criteria were performance of at least one standard deviation below the mean of the Grade 2 norm group on the present spelling test form and a nonverbal IQ (Raven's Colored Progressive Matrices) of higher than 90. Among these children only eight instances of phonemic misspellings of onset clusters and three misspellings of end clusters were observed. Again, it seems quite implausible that the near absence of difficulties with the spelling of consonant clusters could be due to the fact that these children simply produced learned spellings from memory. The majority of the spellings of the poor spellers (i.e., 57%) was orthographically incorrect. Consonant Versus Vowel Spelling In a further step, we examined how the group of 68 first graders spelled consonants and vowels. This comparison was limited to the first occurrences of consonants and vowels in each word. That is, for all attempted spellings we examined how the initial consonant and how the following vowel in the word was spelled. For example, in the case of Sommer, we noted how the /s/ and the /o/ were spelled. In the case of words with initial consonant clusters, only the spelling of the first consonant of the cluster was considered. The three words without an initial consonant were only evaluated with respect to vowel spelling (Äste, arm, ihr). Spellings were evaluated as or-

thographically correct or incorrect (including omissions) and, in the case of an incorrect spelling, we distinguished between phonemically acceptable and phonemically inacceptable spellings. Table 5.3 shows number and percent of spellings falling into these categories. Not considered were the thirteen instances (0.8%) where no spelling was attempted. The majority of these response failures came from one child. Table 5.3 shows that initial consonants were nearly always spelled correctly, and the few errors were all phonemically acceptable. The majority of the errors were of the type schtreiten for streiten (see Table 5.2 for misspellings of sparen, streiten, steht), where the misspelling is actually phonemically more appropriate than the orthographically correct spelling. We also counted as phonemically acceptable the few instances of drägt for trägt. As already noted, in standard Austrian High German pronunciation and, even more so in dialect, the /t/ is unaspirated and pronounced more like /d/. Table 5.3 further shows that the first vowels in the words led to more orthographic misspellings than the initial consonants. The large majority of the orthographic misspellings were phonemically acceptable. As is evident from Table 5.3, among the phonemically acceptable misspellings of vowels, the majority were errors related to vowel length. These errors most often were failures to orthographically mark vowel length at all or, in a few cases, from erroneous markings of vowel length. From the listed misspellings in Table 5.2, it is evident that doubling the consonant following the vowel, which indicates that the vowel is short, was often neglected (e.g., Butter was spelled Buter by the large majority of children). Similarly, lengthening the vowel by the ''silent-h'' or by doubling the vowel letter was also often neglected (e.g., faren for fahren, Schne for Schnee). In some cases, the long vowel was marked but in an incorrect manner (e.g., Schneh for Schnee, ier for ihr). Another problem of vowel spelling was that e was used instead of ä and that eu was used instead of äu (e.g., trekt for trägt, Beume for Bäume). This is a plausible error because both e and ä stand for /e/, and eu and äu stand for /oi/, and morphology constrains the possibilities. For example, in the cases of trägt, Bäume, and Äste TABLE 5.3 Consonant and Vowel Spellings Consonant Vowel Spellings Number Percent Number Percent 1,448 98 1,312 78 Correct 37 2 319 19 Acceptable 212 13 Vowel Length Errors 0 0 56 3 Inacceptable 0 0 5 0 Omission 0 0 17 1 Phoneme Quality 34 2 Vowel Length Errors

consideration of the phonological form of the word stems (spelled: tragen, Baum, Ast) suggests the correct grapheme. Table 5.3 also shows that inacceptable spellings of vowels were produced, but the number was very small. In only five spellings was the vowel grapheme omitted. With one exception, it was the e before the l that was omitted (e.g., schnll for schnell, Fld for Feld). The plausible reason is that in these cases children relied on the letter name /el/ for l. There were a few instances in which vowel category was misrepresented (e.g., Hand for Hund, strieten for streiten, Bäme for Bäume). The majority of the phonemically inacceptable errors as in the case of the phonemically acceptable errors were due to vowel length. For example, trägt (long vowel) was misspelled as träckt or treckt. This can be considered as phonemically inacceptable because ck usually marks that the preceding vowel is short. Conversely, Wind (short vowel) was misspelled as Wiend, the ie being the grapheme for /i:/. One could, of course, argue that the classification of these spelling errors as phonemically inacceptable is overly stringent because children at the end of Grade 1 may not have had enough learning experience to extract the partly context-dependent rules of vowel-length marking. Discussion The main finding of the reported research is that after about 8 or 9 months of instruction, German children tend to produce correct or phonemically acceptable word spellings and give little indication of phonologically caused spelling difficulties. Because German is rather similar to English with respect to phonology, but different with respect to phoneme grapheme consistency, it can be concluded that the latter factor is responsible for the ease with which German children, in comparison to English children, learn to spell. The role of instruction also has to be considered but may not be fully independent from orthographic consistency. Before discussing these broader issues, the main findings are discussed. Spelling of Vowel Phonemes. In the Introduction, it was noted that specifically for vowels, the German writing system is much more consistent than English. This higher consistency was reflected in two sets of findings. Study 1 compared how English and German children spelled the vowels in words with similar pronunciation and spelling in English and German and established two main findings. One was that German children tended to have less difficulty with correct vowel spelling than English children. This was due to the fact that difficulties for the German children were limited to the few words where phoneme grapheme correspondences were ambiguous. Directly related to the difference in consistency was the further finding

that German children, faced with a certain vowel with ambigous phoneme grapheme relations, always produced only one or, maximally, two alternative spellings with higher frequency. The most frequent spelling error of the German children was that they neglected orthographic markers for long vowels (e.g., Sele instead of Seele, Bot instead of Boot). In contrast, English children produced a large variety of different vowel spellings when for a word the correct spelling was not obvious. Some of these misspellings of vowels could not be attributed to phoneme grapheme inconsistency because they consisted of, or included, consonant letters with no relation to pronunciation. Apparently, these misspellings were due to difficulties with phonemic segmentation of word pronunciations and/or with understanding how the segments relate to the letters of the given spelling skeleton. Such errors were nearly absent among the German children. Study 2 with German children at the end of Grade 1 extended the findings of Study 1 with respect to vowel spelling. Again, the large majority of the spellings were correct, and the errors were limited to vowels in which the phoneme grapheme relations are ambiguous. Again, the majority of the misspellings were failures to mark vowel length. Children often failed to double the consonant letter after the vowel to mark shortness (Buter instead of Butter), and they failed to mark that the vowel is long by doubling the vowel letter (Schne instead of Schnee) or by inclusion of h after the vowel letter (Ban instead of Bahn). Other errors related to vowel length were that an alternative to the correct marking for long vowels was used (e.g., ier instead of ihr) or that orthographic markers for short vowels were used when the vowel was actually long, and vice versa. An important finding was that misspellings of the type that the category of the vowel was misrepresented (e.g., Hand for Hund) were nearly absent, as were spelling refusals. Thus, it can be concluded that German children, after about 8 or 9 months of instruction, had no difficulty identifying the category of the vowel in word pronunciations and used the correct letter(s) for vowel category. There were also no difficulties when digraphs had to be used for correct vowel spelling. The present findings on vowel spelling in German fit well with Treiman's (1993) conclusions about the sources of difficulty of vowel spelling observed among her American first graders. Treiman found that her participants had more difficulty spelling vowels than spelling consonants and that this difference was related to both the difference in phoneme grapheme consistency between consonants and vowels and to the difference in the number of letters with which consonants and vowels were spelled. When these two orthographic factors were accounted for, then the phonological category of consonant versus vowel had no effect. The present study similarly found that word-initial consonants led to more correct spellings than first vowels. However, this difference was due mainly to the inconsistency of vowel spelling with respect to vowel length.

Consonant Clusters. Difficulties with the correct spelling of consonant clusters is a finding consistently reported for English children in the first grade (e.g., Snowling, 1994; Treiman, 1993) and for English children with specific spelling problems (e.g., Kibel & Miles, 1994). This difficulty is attributed to the phonemic segmentation problem inherent in the spelling of consonant clusters. It led Treiman to conclude that phonological factors, independent of the inconsistency of English, contribute to early spelling difficulties. In the case of poor spellers, the observed difficulty of consonant-cluster spelling fits well with the general phonological impairment account of dyslexia with phonemic awareness difficulties as a leading symptom (e.g., Stanovich, 1994). In relation to these English findings, it was quite astonishing that difficulties with the spelling of consonant clusters were nearly absent both in normally progressing German children after about 9 months of instruction and in German children with specific spelling difficulties at the end of Grade 2. The finding that German dyslexic children at least after about 2 years of instruction have little difficulty with the spelling of consonant clusters is consistent with other findings from our laboratory showing that dyslexic children exhibit quite high performance levels with respect to pseudoword spelling and phonemic segmentation, which was tested with a vowel substitution task (Wimmer, 1993). As already pointed out, there is a plausible explanation for the absence of difficulties with consonant clusters and of other segmentation-based spelling difficulties among young German spellers and among German dyslexic children. This explanation does not deny that consonant clusters pose difficulties for phonemic segmentation. It does suggest, however, that such segmentation difficulties are easily overcome by the combination of a consistent orthography and an instructional regime that induces children to early word recognition in reading via grapheme phoneme recoding. As previously explained, word recognition via grapheme phoneme recoding provides systematic segmentation training that makes among other things the phonemic composition of consonant clusters quite transparent. Obviously, grapheme phoneme recoding can only be an easy to teach and a reliable word recognition strategy, when the orthography exhibits a high level of consistency between graphemes and phonemes. In this respect, it is important that the consistency of German is higher in the direction from graphemes to phonemes than vice versa. The conclusion from the present findings is that the consistency of an orthography may be a more profound factor for spelling development than generally assumed by English theories. Specifically, the consistency of an orthography in the reading direction, that is, from graphemes to phonemes, may be as important or even more important for spelling development than the consistency in the spelling direction, that is, from phonemes to graphemes. The specific effect of a high level of grapheme phoneme consistency via grapheme phoneme recoding is that

the structural relationship between pronunciation and spelling becomes readily transparent, even for children with phonological impairments. Of course, the present findings do not allow a direct evaluation of this explanation that in its strongest form implies that instructional emphasis on word recognition via phonological recoding has a positive effect on spelling only for consistent orthographies such as German. For such an evaluation and, more generally, for the separation of the role of orthographic consistency and instructional options on spelling acquisition, it is necessary to study the effects of different forms of reading instruction (high versus low emphasis on grapheme phoneme coding) for consistent orthographies and also for less consistent orthographies such as English. Nevertheless, the present findings strongly suggest that a consistent orthography when its structure is made transparent by instruction provides a more favorable orthographic environment for children's first moves into literacy than English, and researchers and teachers working within consistent orthographies are well advised not to base their theories and instructional choices solely on English findings.

Chapter 6 The Development of the Understanding of Number Morphology in Written French Corinne Totereau Marie-Geneviève Thevenin Michel Fayol University of Bourgogne Studying how to learn and how to use written language morphology is one of the less frequently explored fields of research in psycholinguistics. Yet, morphology plays an essential role in written French, especially since many written markers have no corresponding pronunciation (Catach, 1986; Dubois, 1965). This predominantly silent morphology has two general consequences: (a) For children, the learning of these markers and of their functions must be performed without an oral reference (e.g., the absence of phonetic realization of the nominal plural -s in les chiens (the dogs) and of the verbal plural -nt in ils jouent (they play); (b) for adults, the implementation and the control of these markers take place only in reference to the written language. Despite the crucial character of morphology for the mastery of writing, the studies that concern it remain rare and mainly involve the counting of spelling errors or developing taxonomies of errors (Chervel & Manesse, 1989; GirolamiBoulinier, 1984; Jaffré, 1992). In short, there is, to the best of our knowledge, no psycholinguistic approach of the acquisition and implementation of written French morphology. Number Morphology in Oral and Written French The aim of the present series of studies is to make a first contribution to the psycholinguistic approach to the study of acquisition of French morphology for number in relation to nouns and verbs. This work is concerned

with the study of the two most frequent and regular cases: the marking by -s for nominal plurals and by -nt for verb plurals. Dubois (1965), who compared the distribution of oral and written markers for number in French, showed that in the oral modality, only the first segment of phrases and sentences (i.e., the determiner) carries a formal variation whereas in writing there are more markers (e.g., adjective noun agreement) and these tend to apply to the entire phrases and sentences. In spoken French the determiner the is either le or la for singular nouns and les for plural nouns. This modality difference clearly appears when sentences (1) and (2) are compared: (1) La petite poule picore [The small hen pecks] (2) Les petites poules picorent [The small hens peck] In the oral modality, only the la/les difference is perceptible because of the deletion of final consonants in spoken French, whereas in the written modality, all the words are modified. According to Dubois, this asymmetry may be due to the fact that the secondary function of the redundancy of markers in writing is to ensure the cohesion of texts. This cohesion is insured by the intonation in the oral modality. Dubois (1965) also showed that the markers for number are carried by the phrase and the sentence, not the noun or the verb: The probability of finding a marked item depends on the number of elements from a given syntactic class that can have variations. In the oral modality, very few nouns (about 50 out of 25,000), verbs, or adjectives have an audible singular plural difference. Only the most frequent verbs, and especially the auxiliaries, require a phonological variation between the third person singular and plural (e.g., a/ont [has/have]; est/sont [is/are]; fait/font [does/do]). In fact, the number markers are carried by the determiner for the nominals, and, to a lesser extent, by the auxiliary (if present) with regard to the verbs. In writing, the situation is the opposite; very few nouns have the same singular and plural form (e.g., nez [nose]). The rarity of number markers in oral French and, by contrast, their high frequency in writing mean that French children must acquire a specific linguistic subsystem at the same time that they are learning the written language. The reference to oral language is of little use to them, unlike in English. In English, the number differences are orally marked on the noun (e.g., dog/dogs) as well as on the verb (e.g., sings/sing) and adjective noun agreement is not marked in oral or written language. As a consequence, French children must discover the written system of specific features: -s for the nominal and adjectival plurals, -nt for the verbal plurals (in contrast to Ø in singular form); Ø for the adverbial plurals. Once this discovery has been made, then the children have to automatize the implementation of inflec-

tions (Anderson, 1983). As this automatization takes place without any oral support, it is probably longer and more difficult than in other languages such as English. It presupposes a regular and frequent practice of writing (Logan, 1988a, 1988b). However, little is known concerning this acquisition. The experiments reported here attempt to explore how children from elementary school, and, in particular, first, second, and third graders, acquire and use the written markers of nominal and verb plurals in comprehension and production tasks. Brief Review of Studies About the Acquisition of Oral Morphology for Number Most of the studies dealing with the acquisition of number morphology have been conducted on the English language (see Ferguson & Slobin, 1973; Kess, 1992; MacWhinney, 1978). Two types of methods have been used in these studies. The first one consisted of following the same children during several months or several years and analyzing the occurrences of inflections associated to number in spontaneous conversations in natural settings (Brown, 1973; Cazden, 1972; De Villiers & De Villiers, 1973; Mervis & Johnson, 1991). These longitudinal studies provided evidence that the acquisition of number morphology was one of the earliest to develop and that it developed approximately in four phases: pre-pluralization; transitional phase without and then with overgeneralization (i.e., extension of nominal plural markers to other syntactic categories, such as adjectives in English); generalized use and correct extension to unknown words; and lastly adult-type use (Cazden, 1972; Mervis & Johnson, 1991). The second method consisted in presenting drawings depicting situations involving one or several objects, persons or actions. In comprehension tasks, the participants were required to choose the drawing that corresponded to the singular (or plural) item supplied by the experimenter. One drawing displayed several objects or persons, whereas the other one displayed only one object or person. In the production tasks, the children were required to produce the oral item corresponding to a drawing depicting a singular (or plural) situation when they were provided with this same item in the plural (or singular) form (e.g., they had to say "wugs" when the experimenter provided "wug" or to say "wug" when given "wugs" (Berko, 1958; Brittain, 1970; Graves & Koziol, 1971; Keeney & Smith, 1971; Levy, 1987; Nicolaci-da Costa & Harris, 1983, 1984; Newfield & Schlanger, 1968; Solomon, 1972). The results of these studies led to two conclusions and one problem. The first conclusion relates to the fact that the nominal plural is acquired before

the verb plural (Keeney & Wolfe, 1972; Nicolaci-da Costa & Harris, 1984). The precocity of the number marking for nouns in comparison with verbs is interpreted as corresponding to the fact that numerosity is a property of the meaning of nouns more than is the case of verbs. Number primarily affects nouns and is then to be copied onto verbs to secure cohesion. The second conclusion concerns the redundancy of markers. Nicolaci-da Costa and Harris (1983) asked 3- and 4-year-old children to point drawings out or to act out sentences in which the plural marking was more-or-less redundant (e.g., from one marker, as in the demonstrative This sheep jumped/These sheep jumped, to several markers as in This boy is driving his car/These boys are driving their cars). They found that the various markers presented different levels of difficulty in comprehension but the higher the number of different syntactic markers, the better the performance. However, the redundancy of information by repetition of the same marker (e.g., The sheep jumps and runs) had no significant effect on comprehension. The improvement of the comprehension when several markers are involved is due to the fact that having only one marker makes the processing highly fragile; a brief moment of inattention is enough to lose the marker. The redundancy of syntactic information would offset the gaps in the information gathering. The problem raised by several of the previously mentioned studies concerns the relative performance in comprehension and production. Some authors only tested production (Berko, 1958). Others studied production, comprehension, and even imitation (Fernald, 1972; Fraser, Bellugi, & Brown, 1963; Keeney & Smith, 1971; Lovell & Dixon, 1967; Winitz, Sanders, & Kort, 1981). However, the results differ from one study to another. Fraser et al. found that imitation (i.e., repeating a sentence) preceded comprehension (i.e., selecting among two drawings the one which corresponded to a sentence) which preceded production (i.e., formulating an utterance in connection with a provided drawing). Lovell and Dixon (1967) also found this hierarchy. Yet several criticisms were directed at the methodology, particularly the manner of comparing comprehension and production performance (Baird, 1972; Fernald, 1972). In contrast, Keeney and Smith (1971) found that production concerning the morphology number in relation to verbs preceded comprehension. In summary, the previous studies concerning the acquisition of oral morphology for number showed that the nominal inflections are acquired earlier than verb inflections, even in a language such as English in which these inflections are audible. Also, the studies found that comprehension of singularity/plurality is facilitated by the redundancy of markers. However, there is no consensus concerning the precedence of comprehension in comparison with production. In the following studies, these conclusions have been reconsidered and adapted with regard to the study of acquisition of morphology for number in written French.

The Present Study Even though there are a number of studies dealing with the acquisition of oral morphology for number, the same does not apply to the written modality. To the best of our knowledge, only one investigation was conducted in English. Beers and Beers (1992) used Berko's (1958) method by adapting it to written language. As Berko did, they presented singular nonsense words and their associated drawings to children from first to sixth grades. The students were asked to write the plural forms of these nonsense words (the oral plural forms were provided). The present research was designed to study the progressive acquisition of -s, the only plural marker in the written modality despite the diversity of oral plurals (/s/, /z/, /iz/; see Graves & Koziol, 1971). This is a problem that is not very relevant to the French language because the plural markers are very consistent (almost always /s/). The authors found that third graders had acquired the inflections corresponding to the various oral markers. Beers and Beers (1992) provided new information; however, as in Berko (1958), they studied only production and not comprehension. Moreover, the use of nonsense words with children older than 5 to 6 years raises problems. For example, Levy (1987) found that, in a pluralization task, 7-year-old children treated nonsense words in a very different way than 2-year-old children did. In particular, the 7-year-olds made pluralization errors on nonsense words that did not occur with words, whereas the studies of the oral modality showed that the 3- to 4-year-old children succeeded in these same pluralization tasks. It was as if the older children interpreted the task relating to nonsense words as differing from the one they had to perform with words. Finally, Beers and Beers considered only nominal, not verb, plurals. However their study did make a contribution that is elaborated in the present series of studies. The present series of studies was designed to study the acquisition and the implementation of nominal and verb plurals in written French in 6- to 10-year-old children. Berko's (1958) method was adapted to written comprehension and production tasks using words selected from books used to teach reading in first grade. In the comprehension tasks, children were required to match nominal groups (e.g., les chiens [The dogs]), nouns presented alone (e.g., sapin [Christmas tree]), short pronoun verb sentences (e.g., ils sautent [they jump]), or verbs presented alone (e.g., repassent [iron]) in singular or plural form with drawings depicting scenes involving one or several objects, persons, or actions. In production tasks, children were given orally a nominal group or a short sentence corresponding to a drawing depicting one or several objects, persons, or actions and were required to write the words under that drawing. Three hypotheses were tested. First, because children master oral language before learning the written language, it was expected that perform-

ance on comprehension would be higher than performance on production tasks. In comprehension, children can rely on cues such as articles; these cues indicate number in the oral modality (le-la vs. les). However, production tasks require the use of pluralization markers (nominal -s; verb -nt) without corresponding pronunciation. Thus, it is likely that success in these production tasks will be later and less likely than in the comprehension tasks. The second hypothesis concerns the noun verb difference. The results of studies dealing with oral language have shown that nominal plurals were acquired earlier than verbal plurals, even in the English language in which the singular plural difference is audible (cat/cats; he sings/they sing). The same trend is expected in written French because the numerosity concept is more clearly associated with the noun than with the verb meaning. This hypothesis predicts that the correct agreements will be more frequent and occur earlier with nouns than with verbs. The third hypothesis was developed on the basis of the results of Nicolaci-da Costa and Harris (1983). These authors showed that a redundancy of markers made comprehension easier. The same trend is expected in written French. Specifically, the number of correct responses should be higher with phrases (e.g., des chiens [some dogs]) than with nouns presented alone (e.g., chiens [dogs]) or with sentences consisting of a pronoun followed by a verb (e.g., ils chantent [they sing]) rather than with verbs presented alone (e.g., chantent [sing]). The three hypotheses were tested with first, second and third graders individually over several sessions in the same school year (Exp. 1) in order to study the acquisition process. The first two hypotheses were again tested in Experiment 2 with a larger population. In addition, another hypothesis concerning the activation of different markers was tested (for the nouns: Ø in singular form, -s in plural form; for the verbs: Ø in singular form, -nt in plural form). Indeed, the results of Experiment 1 and the review of previous studies showed that the acquisition of the comprehension of markers for nominal and verb plurals occurred over an extended period. However, this performance was obtained with tasks in which children had to match a given word, either singular or plural (e.g., un chien [a dog] or des chiens [some dogs]) to one of two drawings (e.g., one drawing with one dog or another one with several dogs). In such a situation, only one condition of linguistic marking (singular or plural) was explicitly available to the child because only one word was given. The children had to understand that the difference between one vs. several objects depicted in the two pictures corresponded to different markers: Ø/-s for nouns and Ø/-nt for verbs. Therefore, in order to successfully choose the correct picture, the child had to activate the complementary marker of the one given and then choose the correct picture from the two choices. This task of matching only one linguistic item with two drawings is expected to be harder than the task of matching two

linguistic items with only one drawing. Our hypothesis was that children's performance would be better when both different markers were explicitly given (e.g., le chien/les chiens [the dog/the dogs]) to the children, and they would have to match one linguistic item (among the two provided items) with only one drawing depicting either one or several objects, persons, or actions. Experiment 1 This first experiment was designed to study the acquisition of written French morphology. Six- to 8-year-old children were administered tests dealing with comprehension and production of written morphology. Method Participants. Sixty native French-speaking first, second, and third graders who never repeated a year participated in Experiment 1. There were 20 children from each grade. The mean age of children was 6.4 for first grade (range: from 6.2 to 7.1), 7.4 for second grade (range: from 7.1 to 8.5) and 8.4 for the third grade (range: from 8.4 to 9.3) at the beginning of the experiment. Material and Procedure. The material and the procedure were developed from Berko's (1958) and Keeney and Wolfe's (1972) studies. In the production tasks, the children had to produce, in writing, the number inflections for the nouns and verbs. For every trial, a drawing depicting objects, persons, or actions, the corresponding oral formulation, and the written beginning of the phrases (e.g., C'est un _/Il y a deux _ [This is a _/ There are two _]) or sentences (e.g., La cheminée _/ Les cheminées_[The chimney _/ The chimneys_]) were supplied. (See Figs. 6.1a and 6.1b). The children had to write down the last word of the orally given phrases/sentences. In comprehension tasks, children were presented with pictures depicting one or several objects, persons, or actions. Children had to select from two pictures the one that corresponded to the one linguistic item provided with the drawings. The linguistic item could take one of four different forms and was either a noun or a verb: 1. The noun presented alone in either the singular form or plural form (e.g., poisson vs. poissons [fish vs. fishes]). 2. The verb presented alone in either the singular form or plural form (e.g., vole vs. volent [flies vs. fly]).

The verb, either singular or plural, preceded by a pronoun (e.g., il vole vs. ils volent [it flies vs. they fly]). See Figs. 6.1c and 6.1d for examples. Each child was presented with six tasks consisting of ten items each, five in the singular, five in the plural. In order to track the learning process, the first graders were individually given these tasks twice (in April and June). The second graders did the tasks five times (in December, January, March, April, and June). Because of their high performance, the third graders were given the tasks only once (in April). Scoring. Performance was assessed by counting the number of correct responses (out of 10) for each condition. Results Three analyses were performed on the data. First, because we know that the singular form (nominal or verbal) being unmarked appears first and that each task consisted of five items (out of ten) in the singular, it is possible that a child using only the singular form could have a score of 5. Thus, we first attempted to determine if the scores significantly differed from 5 (using a ttest). The results are depicted in Table 6.1. The data show that thirdTABLE 6.1 Experiment 1: Significance of Students' Scores in Relation to 5 (out of 10) Tasks NP VP ANC NC PVC VC First grade - April no no ** * ** ** - June ** no ** ** ** ** Second grade - December ** no ** ** ** ** - January ** no ** ** ** ** - March ** no ** ** ** ** - April ** ** ** ** ** ** - June ** ** ** ** ** ** Third grade - April ** ** ** ** ** ** Note.

graders' performance was always significantly higher than 5 for all tasks. The same was true for second-graders' performance with all comprehension tasks and the noun-production task but not with the verb-production task until April. For first-graders also, the results of the comprehension tasks always differed significantly from 5. By contrast, the results from the nounproduction and verb-production tasks did not significantly differ from 5 before June. In summary, in the production tasks, the unmarked form (i.e., the singular marker) was used for a long time, with verbs even more than with nouns, whereas during the same time period, the comprehension tasks revealed that a certain number of participants interpreted the presence or absence of -s and -nt correctly. Second, several analyses of variance and series of contrasts were performed (using the Sidak test due to the nonorthogonality of the contrasts; see Abdi, 1987). These analyses were designed to test the significance of the differences between the modalities of the variables. Results are displayed in Fig. 6.2. The contrasts enabled us to verify the following hypotheses: (a) Performance on comprehension was always significantly higher than performance on production (all ps < .01); (b) scores on nouns were significantly better than scores on verbs in production (all ps < .01, except in first grade due to floor effect). In comprehension, no significant differences were found in third graders due to ceiling effect. In first graders, the differences were significant only when nouns were preceded by an article and verbs preceded by a pronoun (p < .01). In second graders, the noun-verb difference was only significant when nouns and verbs were presented alone (p < .05)

Finally, according to Siegler's (1987) suggestions, individual profiles were developed session by session, in order to determine whether the trends observed for the groups were true for individual participants as well. There are three types of patterns an individual could display that are incompatible with our hypotheses: higher scores on production than on comprehension; better performance in non redundant situations (noun or verb presented alone) than in redundant situations (article + noun or pronoun + verb), or better results with verbs than with nouns. We determined that a child showing only one of these three patterns was enough to reject it as fitting our hypotheses. Only 10 patterns out of 160 (6.25%) were rejected, that is, only 10 patterns violated one of these expectations. This shows that our expectations were true concerning most individual patterns of performance. In summary, the individual profiles as well as the global analyses confirm that for the acquisition of French number morphology for nouns and verbs, comprehension precedes production, nominal plural is acquired earlier than verbal plural, and the redundancy of markers makes comprehension easier. The fact that comprehension of plural markers precedes production suggests that the recognition of markers is easier than recall of the same

markers in appropriate contexts. However, considering the simplicity of the marking (Ø vs. -s for nouns and Ø vs. -nt for verbs), it seems surprising that comprehension of the number morphology, in particular the verbal one, is late and not strongly established at the end of first grade. The late success in comprehending written noun and especially verb morphology led us to envision that at least some comprehension errors would be due to the children's inability to evoke the complementary marker systematically (Ø when -s is present, for example, or the reverse) and, thus, to understand that the presence of -s with nouns and of -nt with verbs (as opposed to Ø) means that the linguistic item corresponds to a drawing depicting several objects or actions (instead of one object or action). The following experiment attempted to verify this hypothesis. Experiment 2 Traditionally, tasks testing comprehension consist in presenting a linguistic item in the singular or plural form and then asking the participants to select the corresponding drawing depicting a singular or plural situation from two available drawings. In general, the two pictures only differ in relation to the relevant dimension (here, the numerosity of the sets of objects, persons or actions). Thus, it is surprising to observe so many errors in written French among 6- and 7-year-old children who have been using the oral number morphology for a long time. Indeed, even if the written nominal and verb markers are most often not audible, their number is very limited and their occurrence is frequent and regular. Consequently, they should be acquired very rapidly, at least in comprehension. However, at the end of first grade as well as at the beginning of second grade, performance remains weak, in particular for nouns presented alone (about 7 out of 10), pronoun + verb configurations (6.5 out of 10) and, especially, verbs presented alone (6 out of 10). It could be that these weak results are due to the fact that the task consisted of the presentation of only one linguistic item (singular or plural), so the child had to evoke the complementary marker (respectively plural or singular) in order to select the corresponding illustration. This hypothesis predicts that performance should be better when the task presents the two different terms (e.g., le chien/les chiens [the dog/the dogs]) and only one picture and then asks the participants to match this picture with the relevant linguistic item. Method Participants. Two hundred and seventy-two French native-speaking children (136 first graders and 136 second graders) from eight different schools participated in Experiment 2. The mean age of children was 6.6 for first grade (range: from 5.5 to 8) and 7.7 for second grade (range: from 6.8 to 8.11).

Material and Procedure. In January, the children were collectively given a series of production and comprehension tasks concerning the morphological markers for number. The production tasks were the same type as the ones used in Experiment 1 (see Figs. 6.1a and 6.1b). All the comprehension tasks concerned the article + noun or pronoun + verb configurations. However, in half of the cases, the participants received one linguistic item (singular or plural) that they had to match with one of the two provided drawings (one vs. several objects, persons, or actions; see Figs. 6.1c and 6.1d). In the other half of the cases, the participants had two linguistic items (singular or plural) and only one picture available. Thus, the selection focused on the linguistic item (Figs. 6.1e and 6.1f). Results As shown in Fig. 6.3, the findings were the same as in Experiment 1: Performance on comprehension was always better than performance on production (all ps < .0001), and scores on nouns were better than scores on verbs (all ps < .0001). In first grade, performance on nouns was better than performance on verbs for both comprehension (7.64 vs. 5.45) and production (3.84 vs. 3.34). The performance difference between nouns and verbs was larger in comprehension than in production. In second grade, the intensity of the effect was greater in production (7.06 vs. 4.56) than in comprehension (7.99 vs. 7.39). Moreover, consistent with our hypothesis, performance was better when the participants had two linguistic items to be matched with

one picture rather than one item to be chosen from two available pictures (all ps < .0001). However, this trend was significant only with verbs, in first grade as well as in second grade (all ps < .0001). In summary, first graders and second graders knew the number markers and were able to use them correctly (in a matching task with a drawing) when they had the explicit singular-plural difference available. On the other hand, they failed more frequently when they were supplied with only one marker. These data suggest that, at least at a certain period of the learning process, children know the number morphemes, but they are not yet able to activate one of the markers (singular or plural) in the presence of the other (plural or singular). The fact that this phenomenon occurs only for verbs in our data is probably a consequence of the earlier acquisition of nominal markers. Studies with younger children are needed in order to find an equivalent result for nouns. Thus, in the middle of second grade, children seem to have acquired the French nominal and verbal morphology for number. They make few errors in comprehension, and they have a high success rate in production when they have to write down only one word for agreement. However, these results do not imply that these same children are able to use morphemes in more complex conditions. Indeed, we have shown in some previous experiments that even highly educated adults make errors when the agreement task is performed under conditions of cognitive overload (Fayol, Largy, & Lemaire, 1994). Conclusion The results of the two experiments indicate that there are three phases in the acquisition of written morphology for nominal and verbal number. First, children process number markers (Ø vs. -s, Ø vs. -nt) only in comprehension tasks (i.e., in linguistic item picture-matching tasks), but they do not use them in production tasks. Even then, the use in comprehension is constrained by the simultaneous presence of the two linguistic items (Ø vs. -s for nouns; Ø vs. -nt for verbs). It is as if children had acquired the ; Ø plurality -s/-nt), but they were able to interpret these markers only when marker-situation associations (singularity both singular and plural forms were present. However, the first stage occurred only with verbs (Ø vs. -nt), and plural markers for nouns were understood even by the youngest children in this study. It is likely that the same trends would appear with nouns (Ø vs.-s) in an earlier period. In the second phase, performance on comprehension improved alone, without a corresponding increase on production scores. The improvement
< previous page

in comprehension resulted from the capacity of children to interpret any number marker (Ø vs. -s, Ø vs. -nt) without the other marker being present. The students were not yet able to mobilize the number markers in production, but they had enough knowledge to understand the meaning of the presence and/or absence of these markers. The next phase had a different status; it corresponded to the increasing automatization of the use of markers. Indeed, Fayol, Largy, and Lemaire (1994) found that highly educated adults made agreement errors when they wrote sentences that were dictated at the same time that they were engaged in a secondary task. These errors did not occur when they were dealing with the recall task (i.e., dictation) alone. Therefore, adult experts, generally writing without any mistakes, can be made to produce errors under conditions of cognitive overload. These results suggest that acquiring the knowledge concerning number morphology is not enough. The use of number inflections must be automatized in order to be able to use the relevant markers at the right time. However, such an automatization develops over several years. At the very beginning, children who know the markers and are able to use them when explicitly asked to do so, fail as soon as the inflection use must be performed with a concurrent task. At this level, even the graphic transcription is enough to disrupt the agreement process (Bourdin & Fayol, 1994). As the automatization increases, people become more and more able to inflect nouns and verbs at the same time that they are dealing with another activity. However, the success of the agreement implementation remains dependent on the demand characteristics of the task at hand. Even educated adults can make errors when the written task becomes highly difficult. The data suggest that the acquisition of written number morphology in French occurs through procedural learning (Anderson, 1983, 1992; Logan, 1988a, 1988b, 1992). The first phase consists of learning the different linguistic markers and matching these with the corresponding conceptual notions (here singularity vs. plurality). This phase ends when the child can interpret each marker separately (i.e., in the absence of its complementary marker). The retrieval of the complementary marker indicates a certain level of automatization (by activation of elements belonging to the same semantic network). The second phase concerns the transition from a controlled algorithmic application of morphology (e.g., if les or des are present then the noun takes a -s) to the more and more automatized implementation of agreement. This automatization would result from the frequent and regular encounter of configurations (e.g., les/des + noun [the/some + noun]; il/ils + verb [he/they + verb] for example) allowing the matching of relatively consistent conditions with the occurrence of markers (-s/-nt). This automatization leads to a progressive change of the regulation of the management of agreements

from step-by-step control to compilation proceduralization (Anderson, 1983, 1992) and to a reduction of the cognitive cost of this management as well. At the very beginning, controlled management is cognitively very costly and easily affected by any concurrent task. This sensitivity to the addition of another task would explain the weakness of performance in written recall. Children, having to keep the sentences presented orally in memory and to perform the transcription at the same time (Bourdin & Fayol, 1994) do not succeed in simultaneously managing the control of agreement hence, the difference between the performance in explicit and implicit agreement is significant. Increased experience with writing and written text can be expected to reduce the cost of the implementation of certain components which would in turn lead to a progressive automatization. This automatization corresponds to a direct recovery in memory for the inflection (Logan, 1988a, 1988b), recovery that would be fast and not very costly in terms of resources. However, the use of the algorithm still remains possible, for example, for the purposes of control or in situations consisting of contradictory or competing cues (Fayol et al., 1994). Automatization is progressive and still relative. It remains sensitive to the cost(s) of concurrent tasks. If the participant faced an additional task, correct agreement might not occur or occurs by default (i.e., in singular form) hence, agreement errors in complex situations of written production appear. Finally, increasing automatization (and, in particular, with an association such as a plural item in front of a verb activates the plural verbal inflection) leads to the occurrence of new error types (Fayol et al., 1994). This schema of development corresponds to the one that is observed among participants with no difficulties and among participants in school environments that encourage writing. However, it is likely that some problems remain in certain populations. Indeed, Nicolson and Fawcett (1990) have shown that a population of 13-year-old dyslexics was characterized, among other problems, by difficulty in automatizing various abilities, even simple motor skills (e.g., balancing on a beam). Thus, it can be expected that the participants will struggle to automatize agreements and, consequently, make errors more frequently when tasks become complicated. Indeed, complication leads to the mobilization of attentional resources. These resources become unavailable for the management of agreements, which leads to errors. This scenario is all the more plausible because other studies have shown that morphology was particularly sensitive to stress. Indeed, several studies found that it is possible, experimentally, to produce selective impairments (through the use of increased cognitive loads) of the morphology that simulate aphasic disorders (Jarema & Kehayia, 1992; Kilborn, 1991). The empirical findings of the two present studies and the interpretative context presented enable us to understand the acquisition of morphology

Chapter 7 Lexical Spelling Processes in Reading Disabled French-speaking Children Jesus Alegria Philippe Mousty Free University of Brussels The lexical spelling processes of reading disabled French-speaking children were examined by asking the participants to spell frequent and infrequent words containing nondominant transcriptions of inconsistent graphonemes (e.g., /k/ spelled ''qu'' as in "quatre," the dominant spelling for /k/ being "c"). These children were matched with normal controls on their reading ability level. Spelling at the lowest reading level already depended on word frequency in both groups of children. As reading ability progressed, the effects of word frequency increased. However, this increase was weaker in the reading disabled than in the control children. A tentative explanation supposes that word identification processes differ in the two groups. Disabled readers use partial cues that allow reading but do not supply the orthographic lexicon with complete representations of words. French orthography belongs to the family of deep orthographic systems (Gleitman & Rozin, 1977; Klima, 1972). It represents language at the phonological level but simultaneously includes aspects of morphology and syntax. This fact often creates conflicting situations. For instance, the morphological and syntactic aspects of language not marked at the phonological level can, nevertheless, be orthographically represented. For example, the second and third person singular as well as the third person plural are homophonous in several tenses of French verbs: "tu manges" (you eat), "il mange" (he eats), "ils mangent" (they eat) are all pronounced /mase */. Different spellings, however, are systematically associated with each morpheme: "es," "e," and "ent" (see Totereau, Thévenin, & Fayol, chap. 6, this volume).

French orthography also presents complexities at the phoneme-grapheme translation level. For example, the "graphoneme"1 /v/> "v" is consistent: grapho-phonological knowledge is sufficient to correctly spell the phoneme /v/. However, the graphonemes / ã/-> "an'' and / /-> "g" are inconsistent, "en" and ''j" are frequent alternatives, respectively. Specific lexical knowledge is indispensable in order to spell "danger" (danger), instead of "denger," "danjer," or "denjer." Therefore, in order to spell French correctly, the child must possess and use a number of linguistic abilities phonological, morphological, lexical, and syntactic that go far beyond the sound spelling transcription rules. A computer simulation study has shown that pure sound spelling transcription rules allow correct spelling of 88% of phonemes but only about 50% of words (Véronis, 1988). It is widely admitted that two basic spelling procedures are necessary to explain the empirical data: the phonological procedure that constructs spellings using sound spelling transcription rules and the lexical procedure that retrieves spellings of known words from an orthographic lexicon (cf. Brown & Ellis, 1994; Frith, 1980a). Evidence in favor of this view comes from the literature about acquired spelling troubles (Zesiger & de Partz, chap. 3, this volume). On the one hand, patients who have lost the lexical procedure but not the phonological one have been described. These surface dysgraphic patients show a severe impairment in spelling irregular words, but a reasonably good ability to spell regular words and pseudowords (see Beauvois & Dérouesné, 1981, for a French case and Hatfield & Patterson, 1983, for an English case). On the other hand, phonological dysgraphic patients show the opposite pattern of disorders. They have severe difficulty manipulating phonological units, as attested to by their poor performance on pseudoword spelling, but a preserved capacity to spell frequent, even irregular, words (see Shallice, 1981, for a rather clear case). Evidence for the dissociation between these two procedures has been also found in developmental disorders. Boder (1973), for example, proposed a taxonomy including dysphonetic children who have deficits similar to those of phonological dysgraphics and dyseidetic children who have deficits similar to surface dysgraphics. Of special interest are the cases of adults who show developmental syndromes similar to the acquired syndromes but who, nevertheless, have reached good literacy levels (Campbell & Butterworth, 1985; Funnell & Davison, 1989; Goulandris & Snowling, 1991). Current models of reading and spelling development propose a mechanism involving the articulation of lexical and phonological procedures. It 1 According to Véronis (1986), a graphoneme is the couple of a grapheme and its phonematic counterpart. The concept of grapheme corresponds to the functional spelling units of Venezky (1970). So, /s/-> s (serpent), /s/-> c (cigarette), /s/-> t (notion), and /s/-> sc (science) are examples of French graphonemes.

has been suggested that the elaboration of lexical representations results from the activity of the phonological process. The identification of a particular word using phonology progressively elaborates the corresponding orthographic representation that would allow its subsequent lexical identification and spelling. The shift proposed by Frith (1985) from alphabetic to orthographic reading and spelling procedures is a good example of the manner in which these procedures can be articulated in a developmental model (see Ehri, 1980, 1991; Morton, 1989; Perfetti, 1991). The development of the phonological and lexical procedures in normal and reading disabled French-speaking children has been already examined in earlier studies (Alegria & Mousty, 1994, 1996). This chapter further analyzes the development of the lexical process in the context of reading and spelling disability. We concentrate on the spelling of inconsistent, nondominant graphonemes, a procedure that inevitably requires the use of the lexical process. The dominance of an inconsistent graphoneme refers to the frequency of its phoneme-grapheme transcription rule relative to the other possible transcriptions of the same phoneme. For example, the graphoneme /s/-> "c" is nondominant because "c" is, in French, a less frequent transcription of the phoneme /s/ than "s'' (/s/-> ''s" is the dominant graphoneme). Our previous results showed that the performance on such inconsistent nondominant graphonemes was basically nil in beginning spellers, normal as well as reading disabled, indicating that they did not possess an orthographic lexicon at this early stage of spelling development. These children systematically used the dominant version of inconsistent graphonemes. The simplest way to account for these results is to suppose that the first steps in spelling are based on a simplified set of rules introduced most likely by explicit classroom instruction rather than by reading activity. Afterwards, the evolution of spelling with reading ability differed in the control and the reading disabled groups. The performance on the inconsistent, nondominant items increased between second and third grades much more rapidly in the normal group than in the disabled group (Alegria & Mousty, 1994). This acceleration in the spelling development of such items unambiguously indicates that, during this period of time, the orthographic lexicon incorporates a large number of relatively infrequent words in normal readers but, for reasons that remain to be determined, not in disabled readers. Consistent with these speculations, a second study considering normal and disabled children matched on reading level showed weaker word frequency effects in the latter group than in the former group (Alegria & Mousty, 1996). If, as proposed earlier, word representations allowing lexical spelling develop as a result of reading activity, these results suggest that reading processes might differ in normal and disabled readers. The spelling evolution of four inconsistent, nondominant graphonemes is investigated in this chapter. Part of the data come from the study pre-

viously mentioned (Alegria & Mousty, 1996). Two graphonemes (/s/e, i-> "c," and /z/e, i-> "z") already examined are reanalyzed together with two new ones: /k/a, o> ''qu," and / /#-> "ain.''2. As stated before, the correct spelling of those graphonemes depends on the existence of an orthographic lexicon. Besides, it has been hypothesized that the development of an orthographic lexicon should depend on the number of encounters with the individual written words, so strong frequency effects were expected as reading level increases. An important question is whether reading disabled and normal children that have reached the same reading level possess equivalent effects of frequency in word spelling. Method Participants The sample consisted of 38 reading disabled and 75 control children. Reading disabled participants came from a special school for dyslexic children. According to a routine procedure in Belgium, these children had been detected by an official institution that decided to send them to this special school. They have reading and spelling problems but are of normal intelligence (they must have an IQ of at least 85). The group of control children included 19 participants tested at the beginning of Grade 2, 22 at the end of Grade 2, 18 in Grade 3, and 16 in Grade 5. They came from an elementary school where a phonics teaching method was used. For each participant, overall reading efficiency was assessed with a forced-choice sentence completion test (subtest L3 from the ORLEC battery; Lobrot, 1973). This test consists of 36 sentences with a missing word. Five alternatives are proposed on each trial and the children have to fill as many sentences as they can in 5 minutes. The score is the percentage of correct responses obtained in this fixed period of time. As the test goes along, the complexity of the task increases; words become less frequent and syntactic, cognitive and pragmatic aspects of the sentences become more complex. The test thus provides a global measure of reading comprehension that includes both specific (efficient written-word identification processes) and nonspecific (general linguistic and cognitive knowledge) abilities. Three reading level subgroups of reading disabled and control children were then matched on the basis of their Lobrot reading scores. Table 7.1 provides the characteristics of these subgroups. 2 The notation adopted here concerning the phonemic part of graphonemes specifies the orthographic context in which phonemes are included. For example, /s/e, i represents the phoneme /s/ followed by the letter e or i Similarly, / /# represents the phoneme / / at the end of a word.

Six (or four) words, half high-frequency and half low-frequency, were selected for each of the four graphonemes: /s/e, i-> "c," /z/e, i-> "z," /k/a, o-> "qu," and / /#-> ''ain" (see Table 7.2). The classification of words as a function of frequency was made according to frequency counts collected on a corpus of French literary texts (Trésor de la langue française, 1971) and available in the computerized lexical database BRULEX (Content, Mousty, & Radeau, 1990). Obviously, literary texts do not correspond very well to the printed materials primary school children usually see. For this reason, a group of 50 fourth graders were presented with the whole list of words used in the experiment. They were asked to evaluate on a 5-point scale the frequency with which they had earlier seen these printed words: (1) never seen, (2) rarely, (3) from time to time, (4) often, (5) very often. The results are summarized in Table 7.2. The four graphonemes examined were inconsistent and nondominant. That is, they all have a competitor that is more frequent. The first two items, /s/ and /z/, are spelled "s" more often than "c" and "z," respectively. This has been established both on the basis of statistical counts (Véronis, 1986) as well as empirically in a pseudoword spelling task (Alegria & Mousty, TABLE 7.2 Mean Subjective Frequencies (on a 5-point scale) for the Low- and High-Frequency Words Used for Each Graphoneme Graphoneme High-Frequency Words Low-Frequency Words /s/-> "c" ciel cirque cinéma 3.72 cigale macédoine citerne /z/-> "z" douze gazette 2.75 chimpanzé trapéziste /k/-> "qu" quotidien quatre 3.24 quotient marquage main bain pain 4.01 fusain poulain étain / /-> "ain"

1996). The /k/a, o-> "qu" graphoneme has a far more dominant competitor, "c," which represents 96.9% of the occurrences (Véronis). The graphoneme / /#-> "ain" has a competitor, "in," which is dominant in word endings (42.9% and 31.0% for "in'' and ''ain," respectively). The "in" spelling is even more dominant if its position in the word is not taken into account. In wordinitial position, with the contribution of the morphological "in-" (in words such as "invisible" and "incapable") it reaches 98.8%. This creates a strong general bias toward the / /#-> "in" graphoneme. Procedure Children were tested in groups in their classrooms. They were first presented with the pseudoword-spelling task not discussed in this chapter. Then the word-spelling task was presented. Items from each condition were randomly mixed within each task. In the word-spelling task, participants were given an answer sheet on which the carrier sentence was printed with the word containing the target graphoneme missing. The experimenter read the whole sentence aloud and then repeated the missing word in isolation. The child was asked to write it down. Only the letter(s) corresponding to the target phoneme was(were) considered in the analyses (i.e., if the word "cinéma" /sinema/ was used to test the /s/e, i-> "c" graphoneme, only the critical letter "c" was taken into account). Results The mean percentages of correct responses per graphoneme for frequent and infrequent words as a function of group and reading level are presented in Fig. 7.1. A first ANOVA was run with group (control vs. reading disabled children) and reading level (1st, 2nd, and 3rd level) as between-subject factors, and frequency (low vs. high) and graphonemes (/s/-> "c," /z/-> "z," /k/-> "qu," and / /-> "ain") as within-subject factors. As expected, the effects of frequency and reading level were highly significant: F(1, 107) = 550.73; p < .001, and F(2, 107) = 80.37; p < .001, respectively, as well as their interaction, F(2, 107) = 23.77; p < .001. An important question in this experiment concerned the presence of frequency effects at the lowest reading level. Partial analysis showed that frequency was already significant at the first reading level, F(1, 24) = 28.76; p < .001. The main graphoneme effect was significant, F(3, 231) = 34.95; p < .001, as well as its interaction with frequency, F(3, 321) = 31,88; p < .001. The main group effect was significant, F(1, 107) = 20.89; p < .001, indicating that the percentage of correct responses was greater in the control group than in the reading disabled group even though their reading level had been

The group-by-reading-level interaction was significant, too, F(2, 107) = 5.55; p < .001, indicating that the difference between groups increases with reading level. Two interactions (group by frequency and group by graphoneme), however, were nonsignificant (Fs < 1). These results reveal that reading level gives different predictions concerning lexical spelling in normal and disabled readers. Inspection of Fig. 7.1 suggests that the performance with low-frequency words allows us to predict rather precisely the performance on frequent words, independently

of reading ability, for both normal and reading disabled students. In order to explore this issue, a scatterplot considering the score obtained on high-frequency words as a function of the score on low-frequency words is shown in the top panel of Fig. 7.2. The regression equations were basically identical in both groups: slopes reached 1.04 and 0.99, and intercepts 28.3 and 27.6 in the normal group and the reading disabled group, respectively. The dispersion of the results was slightly larger in the latter group than in the former group; the Pearson correlation coefficients were 0.60 and 0.78, respectively (ps < 0.01). Finally, an ANOVA carried out on high-frequency word scores per group, considering low-frequency word scores as covariate, showed that the group effect was not significant (F < 1). A parallel analysis considering the reading scores as a function of the performance on low-frequency words was performed in order to evaluate the predictions about reading differing from group to group. The scatterplot appears in the bottom panel of Fig. 7.2. As expected, the regression equations differed; the intercept was higher in the disabled than in the normal group (26.9 and 14.5, respectively), and the slope was weaker in the former group than in the latter group (0.74 and 0.98, respectively). The Pearson correlation coefficients were 0.40 and 0.81 in the disabled and the normal readers, respectively (ps < 0.01). The ANOVA on reading scores per group, considering low-frequency word scores as covariates showed that the group effect was, as expected, highly significant, F(1,110) = 7.25; p < .01. When the lexical spelling levels were equated, disabled children were better readers than normal controls. Conclusion In order to spell an important proportion of French words, lexical representations containing orthographic specifications are necessary. Earlier studies (Alegria & Mousty, 1994, 1996) have shown that children at the lowest reading level do not possess these representations. Children strongly tend to spell inconsistent nondominant graphonemes (i.e., /s/e-i- > "c") using their dominant transcription (/s/e-i- > "s"). Subsequent studies have compared reading disabled and normal children matched on reading level. When asked to spell low-frequency and high-frequency words containing inconsistent nondominant graphonemes, reading disabled children were inferior to normal children, despite their matched reading level (Alegria & Mousty, 1996). The present study was conducted to extend the comparison of these two groups in lexical spelling. Previous results suggested that children start spelling with a simplified set of rules, probably acquired through classroom instructions, and without any lexically based spelling. The present results partially confirm these notions. The results obtained with inconsistent, nondominant graphonemes

are rather poor at the lowest reading level in both groups of children. At this level, they tend to spell using the dominant graphonemes (/s/- > "s" for instance). Almost 100% of the errors made were of this sort. Some signs of lexical spelling, however, have been observed at the lowest reading level considered here. Reliable and substantial frequency effects were already present for the graphoneme / /-> "ain." The reason is probably that the frequent words containing this graphoneme were indeed the most frequent among those used in the experiment, as indicated by both the published frequency counts and the subjective frequency evaluations collected among primary school children. In more general terms, the differences observed between graphonemes can be attributed, at least partially, to differences in the frequency of the carrier words. In the low-frequency condition, performance was quite homogeneous across graphonemes. Accordingly, subjective frequency evaluations for these items showed rather small variations between graphonemes. On the contrary, in the high-frequency condition, such evaluations revealed important differences among graphonemes, and these differences were reflected in spelling performance. The frequent words containing, for instance, the graphoneme / /-> "ain" were clearly the most frequent. Therefore, it is not surprising that, for this graphoneme, frequency effects appeared more precociously and showed a rapid evolution with reading level. The words containing the graphonemes /z/-> "s" and /k/-> "qu'' were the less frequent and, as a matter of fact, produced the poorest spelling performances. An important question for future research will be to determine whether word frequency alone can fully explain spelling performance. The alternative view consists in attributing an autonomous role to some graphonemes, possibly in some particular contexts. The most important fact revealed in the present study was that reading disabled children were poorer at lexical spelling than normal readers matched on reading level. This suggests that their word identification processes allow them to read but not to develop an efficient orthographic lexicon. The results of the multivariate analysis are in agreement with this notion. Disabled readers showed higher reading performance than normal readers paired on spelling level, and this was especially true at the lowest spelling levels. This finding suggests that more reading exposure is necessary to the disabled readers to achieve the storage of orthographic word representations. It is interesting to contrast these results with those relating the spelling of infrequent and frequent words. In this case, disabled and normal readers shared exactly the same regression equation, suggesting a unique mechanism of spelling in both groups of participants. This does not seem to be the case for reading. As mentioned previously, the mechanism proposed to explain the development of orthographic representations supposes that the successful iden-

tification of individual words while reading progressively elaborates representations that allow subsequent lexical reading and spelling (Ehri, 1980; Frith, 1980b; Gough & Juel, 1991; Jorm & Share, 1983; Perfetti, 1991; Stanovich, 1986). According to this account, phonologically based word identification processes are the dynamic element in the elaboration of lexical representations of words. The results obtained with normal and disabled readers suggest that reading level, as it was evaluated in this experiment, gives different predictions in each group concerning the size of the corpus of orthographic representations that the participant possesses and/or the quality of the items contained in this corpus. Two factors might explain this fact. One concerns the word-identification processes and the other concerns the storage of orthographic representations. Let's first consider the notion that disabled and normal readers matched on reading level might differ in their word identification processes. Some authors have systematically compared reading and spelling abilities in the same children. They have found that some of them present a homogeneous pattern of success; they are either good readers and good spellers or poor readers and poor spellers. Some children, however, present a mixed pattern; they are good readers but poor spellers (Bruck & Waters, 1990; Frith, 1980a; Waters, Bruck, & Seidenberg, 1985). A discrepancy between reading and spelling is not surprising. Indeed, spelling involves recalling, a more difficult activity than reading, which is an act of recognition. Frith quite reasonably noted that reading can be achieved using partial cues, whereas spelling requires full cues. It has been demonstrated that the mixed children reach reading levels that are equivalent to those of the good readers-good spellers by using compensatory reading procedures (Bruck & Waters, 1990; Waters et al., 1985). Their high performance on reading tests was obtained by using sentence context. Several studies (e.g., Perfetti & Hogaboam, 1975; Perfetti & Roth, 1981; Stanovich, 1980) showed that poor readers' word identification depended to a greater extent on sentence context. All readers can take advantage of context to predict the nature of the following items in a sentence, but orthographic word processing in good readers is too fast to allow guessing to be revealed. The basic feature that characterizes good readers-good spellers is their word processing mechanisms; these mechanisms are complete, (i.e., in Frith's terms, based on full cues instead of on partial cues, as is the case for poor readers). On the basis of these data, it is tempting to speculate that word processing based on full cues is a necessary condition for the elaboration of an orthographic lexicon that could be used in word spelling. Another potential explanation for reading disabled students having difficulties developing an orthographic lexicon has been illustrated by Goulandris and Snowling (1991). According to these authors, surface dyslexia may be due to a nonspecific visual memory deficit. They have described the case

of a successful reader presenting a developmental surface syndrome with severe difficulties in tasks requiring visual recognition of geometric shapes and reproduction of Greek letters or abstract letter-like sequences. They assume that this impairment has prevented the participant from developing detailed orthographic representations of words. Their account may, in principle, explain the use of partial cues in reading. This tendency simply results from the participant's inability to store full cues because of a general visual memory deficit. This notion contrasts with the influential criticism provided by Vellutino (1979) against peripheral accounts of dyslexia. However, more recent evidence based mainly on brief presentations and psychophysical procedures (see Aaron, 1993; Lovegrove, Martin, & Slaghuis, 1986; Lovegrove, Slaghuis, Bowling, Nelson, & Geeves, 1986; Slaghuis, Lovegrove, & Davidson, 1993) suggested that subtle visual deficits may exist in the reading disabled and that the crucial variables may not have been clearly identified. In addition, the case reported by Goulandris and Snowling suggests that peripheral deficits may characterize at least some disabled readers (see the cases reported by Rayner, Murphy, Henderson, & Pollatsek, 1989, or by Valdois, Gérard, Vanault, & Dugas, 1995).

Chapter 8 Learning to Spell in the Classroom Linda Allal University of Geneva Skill in spelling, even more than skill in reading or in mathematics, is primarily a product of school learning. One might argue that all research on spelling acquisition, even when conducted in a developmental perspective, is invariably concerned with learning shaped in a classroom setting. The focus of the present chapter is on the conditions of learning to spell in the classroom, particularly during the first 6 years of schooling. It examines alternative instructional approaches, proposed activities and tools, aims and observed outcomes. The chapter is based on literature reviews and presentations of research conducted both in English-speaking and in French-speaking countries. Without attempting to cover all curricular trends, it identifies the main features of the most widely adopted instructional methods. Over the past 20 years, a large number of publications have presented instructional approaches designed to foster students' writing competency (e.g., Chiss, Laurent, Meyer, Romian, & Schneuwly, 1987; Dipardo & Freedman, 1988; Englert, Raphael, & Anderson, 1992; Graves, 1983; Scardamalia & Bereiter, 1986; Turco, 1988). In most cases, priority is given to higher order processes of text production (planning, revising, sentence generation), whereas lower order processes such as spelling tend to be neglected. Researchers in the area of language instruction often seem to share the attitudes of teachers and students for whom spelling is a necessary but altogether disliked component of the school curriculum (Downing, DeStefano, Rich, & Bell, 1984). As a school subject, spelling can cover varying ranges of content, thus making it difficult to compare research conducted in different countries.

Studies of the acquisition of French spelling generally consider two areas of orthographic knowledge as defined and taught in school: 1. Lexical or usage aspects of spelling (phoneme-grapheme transcription as well as morphemic and ideographic features of word construction), 2. Grammatical aspects of spelling (morphemes specifying relationships, particularly agreements, between sentence components or between components of different sentences). These aspects of spelling are closely linked to topics studied in other domains of the French language curriculum: grammar, verb conjugation, and punctuation. Thus, spelling instruction, broadly defined, often extends to all conventions of written language transcription. Studies of English spelling acquisition sometimes have a similar scope when they investigate mastery of writing mechanics (a rather inappropriate but widely used term referring to knowledge of spelling, syntax, and punctuation conventions). However, most English language studies focus exclusively on the spelling of individual words. In addition to obvious differences between the French and English languages,1 differences in instructional traditions influence the orientations and methods of spelling research, as is subsequently shown in this chapter. The chapter is organized in four sections. The first section presents our conceptual framework that distinguishes two categories of instructional approaches as well as four basic features of teaching-learning activities in the classroom. In the next two sections devoted to each instructional approach, we analyze research findings on spelling acquisition in English and 1 An example will help to show why French spelling instruction must grapple with a wider range of problems than those encountered in English. In the following sentences, spelling difficulties that occur in French but not in English are underlined: (a) The neighbor's daughters sing beautiful Greek songs; (b) Les filles de la voisine chantent de belles chansons grecques. In addition to the lexical aspects of spelling that can be quite challenging in both languages (e.g., neighbor, chanson), the French sentence entails the following orthographic difficulties linked to inflectional morphology: (a) plural inflections on nouns are usually not marked orally (fille and filles, chanson and chansons are pronounced the same); (b) third-person plural verb inflections are often not marked orally (chante and chantent are pronounced the same); (c) most determiners and adjectives have to agree with nouns in number and in gender and the inflections are often not marked orally (same pronunciation for bel, belle, belles, and for grec, grecs, grecque, grecques); (d) modifiers separating the subject and the verb occur more often in French and thus increase the likelihood of incorrect verb inflections (voisine chante instead of filles chantent). Moreover, third-person referential pronoun agreement is often not marked orally in French and increases the probability of incorrect plural inflections, for example: (a) ''The neighbor's daughters. . . .Having lived here for 20 years, they speak French fluently." is clearly distinguished from " . . . Having lived here for 20 years, she speaks French fluently." (b) On the other hand, "Les filles de la voisine. . . .Habitant ici . . . , elles parlent. . . ." cannot be distinguished orally from "Habitant ici . . . , elle parle . . . "

in French. A brief concluding section raises the question of possible links between different approaches to spelling instruction. Instructional Approaches and Features of Classroom Learning Instructional approaches for spelling acquisition can be classified in two broad categories, as shown in Fig. 8.1. The first type of approach aims at specific learning of spelling skills. Although advocates of this approach recognize that spelling problems arise and must be minimally dealt with in all reading and writing activities in the classroom, they consider it essential to organize a substantial body of instruction focused specifically on spelling. This approach is based on the assumption that spelling knowledge acquired in specific instruction will transfer to more complex reading and writing tasks. Specific instruction based on memorization, various types of exercises, and word and text dictation is intended to develop skills that will be reinvested in subsequent situations of written communication. In the second instructional approach, spelling acquisition is integrated in activities of text production or in situations involving both reading and writing. This approach aims at creating conditions for spelling acquisition within an authentic context of communication. Writing tasks are both the departure point and the overall framework for studying various aspects of spelling. Although specific instructional activities, such as exercises, may be used to consolidate spelling skills by providing additional practice on problems identified in the writing tasks, they are proposed as follow-ups on writing rather than as self-contained learning situations. The underlying

assumption of the integrated approach is that extensive writing activities will progressively lead to a functional organization of the student's orthographic knowledge and skill. Although teachers may adopt mixed instructional strategies combining some aspects of both specific and integrated approaches in classroom practice, it is useful to differentiate the contrasting conceptions underlying each approach. In order to specify these conceptions, we consider four important features of teaching-learning processes in the classroom. The following is a brief, general definition of each feature. The usefulness of these features for comparing different approaches to spelling instruction is shown in subsequent sections of the chapter. 1. The concept of didactical transposition2 offers a fruitful theoretical framework for analyzing instructional content. Introduced by Chevallard (1985) and developed by Bronckart and Schneuwly (1991) in the field of language instruction, this concept describes the transformations between successive knowledge states that account for the content structure of disciplines taught in school. Scientific knowledge and relevant social practices in a given domain constitute the initial reference points from which the subject matter to be taught in school is selected and specified. The selected topics are then consolidated into an autonomous configuration as the instructional content of a particular curriculum. We find it useful to extend the sequence to include two additional transpositions: (a) the transformation of curricular content into subject matter actually taught (or transmitted by instructional materials), and (b) the transposition of what is taught into knowledge in fact acquired by students. 2. The contextualization of school learning is a long-standing concern (Dewey, 1938/1963) that is receiving new emphasis in contemporary work on "situated cognition" (Brown, Collins, & Duguid, 1989). The basic assumption is that declarative and procedural knowledge acquired in school will be more easily activated in out-of-school settings if the conditions of class-room learning closely approximate the real-world contexts of knowledge utilization. This assumption is grounded in a sociocognitive conception of learning as "apprenticeship" in a set of cultural practices (Collins, Brown, & Newman, 1989). In contrast, the highly decontextualized tasks usually employed in school are derived from two interrelated phenomena: (a) the process of "content reification" demonstrated in research on didactical transposition and (b) the classical conception of learning as an accumulative process proceeding from the mastery of basic skills to their application in more complex situations (Needels & Knapp, 1994). 3. Studies by Sweller (1988; Sweller & Chandler, 1994) showed that schema acquisition and automation are affected by the cognitive load induced by 2 We have made the translations of all quotations from French-language references.

two aspects of an instructional activity: (a) its intrinsic properties (in particular, the number of elements to be dealt with and the degree of interactivity among elements) and (b) the extraneous properties of the instructional format. This research shows that instructional design that modulates the cognitive load of a task is a powerful means of optimizing learning. In the area of language learning and utilization, problems of cognitive overload can explain certain types of errors committed by experts who master a spelling rule but fail to apply it (Fayol & Largy, 1992). Moreover, studies of individual differences in writing (McCutchen, Covill, Hoyne, & Mildes, 1994) have suggested that increasing fluency of so-called lower level skills (sentence generation, lexical retrieval) can reduce working memory load and thereby allow writers to invest more cognitive ressources in higher level processes such as online planning and reviewing. 4. Investigations of school learning show that both cognitive and metacognitive aspects of self-regulation play an important role in knowledge acquisition and in the use of existing skills to carry out new tasks (Allal & Saada-Robert, 1992). As conceptualized by Vygotsky (1978), the learner's regulation strategies are developed by a process of internalization, defined as "internal reconstruction" of socially mediated regulations (p. 56). In the classroom, this mediation can be provided by interactions with the teacher, or with more advanced peers, or by other forms of instructional scaffolding (interactive material or tools). Specific Instructional Approaches to Learning to Spell Learning to Spell in English Specific instructional activities for learning English spelling are nearly always focused on individual words, isolated from any surrounding linguistic context, or in cases where words are inserted in sentences or in a text, the context has a limited effect on how each word is spelled. A long-standing debate exists, however, concerning the relative effectiveness of two forms of instruction: (a) memorization of lists of words, or (b) systematic analysis of spelling regularities by a series of appropriate exercises. Memorizing Word Lists. A century ago, Rice launched a large-scale survey of spelling ability based on tests administered to 13,000 children in fourth through eighth grades and on interviews with 200 teachers (Venezky, 1980). Although his data showed no direct relationship between teaching method and learning outcomes, the findings led him to two conclusions regarding prevailing instruction: neither rote memorization of arbitrary word lists, nor

the teaching of spelling rules, accompanied by endless lists of exceptions, could be considered as truly effective. Rice's recommendations retained memorization of word lists as the basic approach to spelling instruction but proposed several ways of organizing the lists (e.g., grading words by orthographic differences and by use) and suggested that a limited number of basic rules be taught (e.g., rules for suffix morphology). Studies by Horn (1919, 1960), conducted over a period of 40 years, showed that teaching rules of phoneme grapheme correspondences had little positive impact, thus reinforcing the idea that spelling acquisition must rely essentially on memorization of a large body of words. In a review article, Graham (1983) presented the principles that can be derived from the numerous studies of spelling instruction based primarily on word-list memorization. These approaches consider spelling to be a complex but relatively independent skill that does not develop by transfer from other curricular areas (Allen & Ager, 1965). Spelling acquisition, therefore, requires specific instructional activities distinct from classroom situations that focus on the communication functions of reading and writing. For Graham (1983), the essential instructional objective is acquisition of a ''basic spelling vocabulary" (p. 562) (i.e., a stock of words that can be automatically retrieved in memory). Memorization of word lists is the primary means of attaining this objective, but it can be usefully supplemented by instruction in a small number of key rules that apply to a large number of words. In addition, the student is supposed to acquire two skills dictionary use and proofreading that facilitate use of orthographic knowledge in writing activities. The instructional sequence proposed by Graham (1983) for elementary school Grades 1-6 is organized in four main phases: 1. The lists to be studied are composed primarily of words frequently used, or likely to be used, in student writing projects. The teacher can create lists based on tabulations of words actually used in class or can refer to published lists. Following recommendations from Horn's (1954) research, words are presented in columns rather than being inserted in sentences or in paragraphs. Each word is presented as a whole, unsegmented unit, without syllabication or indications (e.g., colors, typography) drawing attention to so-called "hard spots." 2. An initial test, usually based on transcription of dictated words, allows identification of the words spelled correctly and incorrectly by each student. The mistakes are corrected by the child rather than by the teacher. Subsequent study efforts focus on the individual list of misspelled words compiled for each student. 3. Word study is based on a systematic technique for effective memorization. Graham (1983) presents five experimentally validated techniques,
< previous page

next page >
< previous page
page_135
next page > Page 135
including the Horn (1954) "Method 2" that includes the following steps (p. 565): 1. Pronounce each word carefully. 2. Look carefully at each part of the word as you pronounce it. 3. Say the letters in sequence. 4. Attempt to recall how the word looks, then spell the word. 5. Check this attempt to recall. 6. Write the word. 7. Check this spelling attempt. 8. Repeat the above steps if necessary. The study technique is presented on a worksheet that the student learns to use with teacher guidance until the steps are internalized; the student can then proceed at an individual pace without supervision. The effectiveness of the technique is explained by its reliance on combined visual, auditory, and kinaesthetic representations of word structure. 4. After a study period, the student is retested on the word list, and the words misspelled are incorporated into the next list (or a later list) to be learned. The effectiveness of the approach comes from the systematic repetition of the "test-study-test" cycle (Fitzgerald, 1953; Yee, 1969). In addition, Graham (1983) proposed the use of spelling games such as hangman, scrambled words, and spelling bingo, but he insisted on the fact that they should "only supplement rather than supplant" systematic word memorization (p. 565). He also advocated tutoring as a means of reinforcing the efficiency of individualized word study. We can summarize the characteristics of the word memorization approach to spelling as follows: Strong emphasis is placed on individualized instruction. An initial list is proposed to the entire class, but very rapidly thereafter, different lists are constituted for each student on the basis of his or her spelling mistakes. It is also a highly structured approach that is "planned, monitored and modified on the basis of assessment information" (Graham, 1983, p. 563). Student motivation is encouraged by the study of words likely to be rapidly reused in writing, by the progress resulting from application of the study technique and, to a lesser extent, by a certain diversification of activities (such as the introduction of games). On the whole, this approach involves many classical features of mastery learning. It is not, however, incompatible with cooperative learning methods involving team study and peer tutoring (for example, the CIRC program developed by Slavin, Stevens, & Madden, 1988).

Study of word lists is very widespread in elementary schools, but many teachers do not apply the principles that assure instructional effectiveness. Ineffective practices include lack of individualization (all students study the same lists), badly designed exercises (students manipulate words without engaging in sufficient spelling practice), and limited content relevance (too much time spent learning low-frequency words rarely used by students in their writing). Systematic Study of Spelling Regularities. In contrast to the research by Horn (1954) showing the lack of regularity of English spelling, studies based on more sophisticated linguistic models have provided a more optimistic view of the possibility of defining rules that can predict a major portion of phoneme grapheme correspondences by taking into account variations in position, environment, and stress (Hanna, Hanna, Hodges, & Rudorf, 1966). These studies lend support to the development of instructional approaches focused on spelling patterns, that is, on regularities of sound letter relationships and on underlying linguistic rules that account for regularities. For Hodges (1982), "learning to spell involves developing an understanding of the total framework of English orthography and the interrelationships among phonological, morphemic, and other language factors which the orthography reflects" (p. 289). An instructional approach based on systematic study of spelling patterns has been proposed by Henderson (1985) and Templeton (1991). In this approach, spelling is not considered as a specific skill but as one manifestation of "word knowledge" progressively acquired through all reading and writing activities conducted in the classroom (Templeton, 1991). It is believed, however, that in addition to these activities, teachers must provide explicit spelling instruction focused on words studied out of context. Direct instruction, conducted in small groups or with the entire class, aims at allowing the student to discover, analyze, and manipulate orthographic patterns and rules. The purpose is to insure systematic consolidation of knowledge acquired partially and implicitly through reading and writing. Developmental studies of spelling acquisition (Henderson, 1985; Templeton, 1989, 1991) have provided a foundation for specifying the progression of subjects to be studied during the elementary school grades. The recommended sequence starts with basic letter patterns within one-syllable words, goes on to variations of spelling linked to phoneme position, environment and stress, then to polysyllabic words and patterns at syllable juncture, adds the study of morphemic elements (e.g., prefixes, suffixes) and, finally, offers more advanced activities dealing with the relationships among meaning, morphology, and derivation. Three types of instructional activities are included in this approach (Templeton, 1991). First, it is accepted that a certain amount of word memoriza-

page_137
next page > Page 137
tion must take place, especially at the beginning, so the student can acquire a sufficiently large sight vocabulary to which word analysis techniques can then be applied. However, in contrast with the memorization approach described previously, words are grouped in lists to show their regularities, the systematic variations of letter patterns, or derivational relationships. Second, during the lessons given by the teacher, the students learn to observe, compare, decompose, and construct words. Importance is given to the discovery of patterns inferred by students on the basis of the manipulations they carry out. Their activity is, nevertheless, strongly guided by the teacher's interventions and by the pre-established structure of the material (corpus of examples). Because this material is constructed to facilitate the intended discoveries, it does not necessarily correspond to the spelling difficulties that are commonly encountered in the students' personal writing. Third, in order to consolidate the discoveries made during spelling lessons, the students apply the same principles in various types of individual exercises (fill-in-the-blank, matching, sorting, transformations, construction, or completion of classifications and analogies, etc.). Lessons and exercises are designed not only to foster students' spelling skill in itself but also "the construction of abstract knowledge structures that will underlie their advancing word knowledge and afford more efficient effective reading and more elaborated writing" (Templeton, 1991, p. 198). Some programs of instruction adopt a more eclectic view. For example, the aforementioned activities of word sorting, analysis, and classification may be carried out on material of the type usually employed in the classical memorization approach, that is, on an individualized bank of words belonging to the student's reading and writing vocabulary (Sulzby, 1980). Learning to Spell in French Research on the acquisition of French spelling has several long-standing orientations (Jaffré, 1992): theory building based on findings from linguistics, psycholinguistics, and cognitive psychology; descriptive research using comparative, correlational, or historic methods; action research aimed at implementing new instructional approaches. There exist, on the other hand, relatively few experimental or quasi-experimental field studies similar to those conducted in English language countries as a means of verifying the effects of different instructional conditions on student learning. Three specific instructional approaches are used in teaching French spelling. For the lexical aspects of spelling and for verb conjugation, word memorization is often combined with the systematic study of orthographic regularities. These approaches relied, for more than half a century, on large-scale surveys giving guidelines for sequencing topics according to their difficulty

level as defined by average age of acquisition. One can mention, as examples, the Dubois-Buyse word scale, based on a survey conducted between 1936 and 1939 with nearly 60,000 Belgian students and periodically revised since then (Guion, 1974), and the conjugation tables established by Roller (1954) on the basis of surveys of Genevan school children. In French language instruction, the study of orthographic regularities extends over a wider range of content than in English spelling instruction: In addition to lexical patterns, a sizeable number of rules governing the grammatical aspects of French spelling are analyzed by various types of inductive and deductive exercises. Moreover, French spelling instruction relies heavily on a device generally unknown in English language classrooms: la dictée. A dictée usually entails dictation of a coherent text excerpt (e.g., a paragraph) composed of several sentences. The length and the complexity of the texts vary: In the beginning elementary grades, only two or three short, basic sentences are dictated, whereas in the formal competitions for adult specialists, the texts are composed of lengthy, interconnected sentences involving numerous orthographic complexities. Traditionally, dictation texts are drawn from literary sources, but they are sometimes invented by teachers so as to limit (or, on the contrary, maximize) the number of difficulties the student will encounter. Text dictation has been used for more than a century as an instructional exercise and as a means of assessing the knowledge acquired by students in more restricted activities focused on word memorization or analysis of spelling regularities. Compared to these latter activities, text dictation offers one undeniable advantage: The student must link together all aspects of spelling (lexical and grammatical knowledge) in a text-based framework that requires reflection not only on sentence components but also on relationships between sentences. Text dictation allows treatment of aspects of French spelling that cannot be dealt with in exercises carried out on isolated words or unconnected sentences. But, beyond this specific instructional advantage, la dictée has often been endowed with a much more ambitious educational mission: a cultural function of conveying feeling for bel usage as well as other unverifiable virtues such as contributing to "the child's corporal and mental mastery" (Vial, 1970, p. 85). In spite of recurrent criticisms of text dictation as a pedagogical tool, it continues to occupy an important place in the Official Directives of the French school system (Guion, 1974) and is the most frequently declared means of teaching spelling in surveys of teachers (Michelet, 1984, cited in Chervel & Manesse, 1989). The effectiveness of text dictation on student learning has not, however, received thorough investigation by well-controlled empirical studies in the classroom. Chervel and Manesse have combined two interesting lines of research: (a) a meticulously documented historical study of the role of la dictée in French elementary and secondary

schooling, and (b) a survey comparing student performance across the span of a century (3,114 dictation copies produced between 1873 and 1875 and an equivalent number based on the same text collected in 1987). The survey invalidates the persistent myth of declining spelling skills among today's schoolchildren, but the historical study is even richer in instructional insights. We summarize several of the key findings. Before the introduction of text dictation, around 1830, prevailing instruction consisted primarily of copying and memorizing isolated words or sentences. Several aspects of this classical approach were similar to modern word memorization methods: The student worked individually, with a minimal amount of direct teacher guidance, on material that varied from one learner to another. However, in contrast with modern methods, little concern was given to student comprehension of the content to be memorized. "One often sees students open randomly any book they come across and then undertake the thankless task of blindly transcribing words and sentences whose meaning is totally lost on them," reported Inspector Cadet in 1881 (Chervel & Manesse, 1989, p. 126). In this context, it was not surprising that the introduction of oral dictation of texts commented by the teacher constituted a major instructional innovation, vigorously defended by the school administrators and pedagogues of the period. Chervel and Manesse (p. 136) explained the progressive adoption of the new method throughout the school system in the following terms: /La dictée/ has one merit that ranks it very much above other exercises. It obliges the teacher to break completely with the "individual mode" of instruction that was prevalent before 1850. It obliges him to direct his class, one might even say, to "teach to his class." . . . It allows him to use the blackboard, for which a lively campaign promoting its introduction in the classroom was underway at the same period. From the mid-1800s on, published collections of dictation texts, graded by difficulty level, fostered increasing use of this instructional tool by teachers. The effectiveness of this new approach, which by 1870 had become almost a daily feature of French classrooms, was confirmed by impressive increases in student spelling skills across the nation, as substantiated by inspectors' reports and by results of elementary school final examinations. We find it interesting to relate this observation to explanatory variables identified in contemporary research on teaching. In studies based on the process product paradigm (Brophy & Good, 1986), it has been found that student-learning outcomes are strongly dependent on two variables (among others): (a) engaged time spent on a given task and (b) direct instruction carried out with expertise and enthusiasm by the teacher. It is intriguing to consider that the observations regarding the effectiveness of dictations, as

next page >

formulated by French inspectors between 1870 and 1880, may constitute an early validation of the role of these two key variables of process product research. Today's approaches to French spelling instruction (e.g., Chiss & David, 1992) focus primarily on linguistic and psychological principles that can guide interpretation of student answers and explain spelling errors. Whatever the task (memorization, analytical exercises, text dictation), an attempt is made to discover student representations of the orthographic system and to develop instructional interventions on this basis. The theoretical contributions of the HESO group (Catach, 1978) offer a framework for the development of error typologies and for the construction of instructional tools (Jaffré, 1992). This perspective tends to give more importance to the presumed validity of scientific references than to controlled empirical testing of instructional conditions in the classroom. Comparison of Approaches for Specific Spelling Instruction The four features we have chosen to describe teaching learning processes in the classroom allow us to compare the approaches aimed at specific spelling instruction, that is, word list memorization (approach M), systematic study of spelling regularities and rules (approach R), and text dictation (approach D). Didactical Transposition. In the M approach, the scientific knowledge base is codified (spelling specified in the dictionary) and the instructional content is often prescribed institutionally (word lists defined in curricular materials), but these basic reference materials are accompanied by little or no theoretical elaboration. In contrast, the R approach refers explicitly to scientific knowledge in several areas of linguistics (phonology, morphology, etc.) and to even broader cultural or literary concerns (e.g., relations between meaning and etymology). The transposition of developmental data guides the progression of instructional content, and the activities to be carried out (analysis, classification, etc.) are embodied in specific instructional tools (teacher manuals, textbooks, workbooks). Teachers need sufficient training in the underlying theoretical models to be able to create classroom activities that go beyond the examples provided in the curricular material and to interpret children's spelling errors and strategies. The D approach lies at the crossroads of several tendencies in didactical transposition linked to its pivotal use both as a means of consolidating prior learning based on M and R methods and as a starting point for subsequent M and R activities. Moreover, given the pervasiveness of dictations in French spelling instruction, Chervel (1977) formulated a hypothesis suggesting an
< previous page
page_140
next page >
< previous page
page_141
next page > Page 141
inversion of the usual direction of didactical transposition (from scientific concepts to teaching content). He believed that in order to improve the efficiency of instruction in spelling, it was necessary to create a ''school grammar" designed in terms of orthographic utility. This school grammar has exerted enduring influence on the scientific grammar models developed by linguists while remaining largely impervious itself to scientific criticisms. What learning outcomes can be expected at the end of the chain of didactical transposition when employing each instructional approach? The effectiveness of the M approach depends on the student's capacity to apply the prescribed memorization techniques. It assures knowledge of language (mastery of spelling usage) without developing knowledge about language. In the R approach, student learning depends primarily on reasoning and logical analysis. Acquisition of knowledge about language (e.g., rules governing orthographic patterns) is considered essential for the development of spelling skills embedded in general knowledge structures. The D approach aims at synthesis of several language competencies and to achieve this goal strongly advocates acquisition of knowledge about language. Classroom lessons and exercises on grammar, conjugation, and vocabulary all have a common goal: to foster mastery of spelling conventions and their systematic application in text transcription. Contextualization. In both the M and R approaches, spelling is learned principally by decontextualized activities (study of unrelated words or sentences). However, the transfer of orthographic knowledge to more global reading writing activities is based on two different theoretical principles: in the M approach, transfer is facilitated by the study of words similar to those used in the student's personal writing, whereas in the R approach, transfer is supposed to result from the elaboration of general lexical and grammatical knowledge structures. The D approach offers a greater degree of contextualization from a linguistic viewpoint. The fact that all aspects of spelling are dealt with in a text framework is expected to facilitate the transfer of knowledge acquired in dictation to the student's personal text production. Transcription of a dictated text remains, nevertheless, considerably more artificial than the text production tasks required in real-life settings. Cognitive Load. In the M and R approaches, the decontextualized form of specific spelling activities is justified by an implicit assumption of reduced cognitive load by isolating the elements to be learned from any surrounding noise produced by other elements of a sentence or text. The D approach is often considered to provide the opposite situation: The student is confronted with a complex spelling task in which he must think of all aspects of spelling and their interrelations. The practice of prepared dictations (by appropriate
< previous page
page_141
next page >
< previous page
page_142
next page > Page 142
lessons or exercises) attempts to facilitate student management of the otherwise heavy cognitive load imposed by text dictation. Regulation of Learning. The M approach attempts, by the repetition of a simple study technique, to assure progressive internalization of the different operations and, thereby, foster self-regulated management of spelling acquisition. In the R approach, the regulation of learning comes from student interactions with the teacher and with other students and from the organization of the instructional material. Expert teacher guidance is required to foster optimal use of the material. The D approach also relies heavily on teacher guidance, especially by think-aloud modeling of the reasoning to be carried out when transcribing dictation and when re-reading the dictated text. In some varieties of this approach, interaction among students working in small groups or dyads allows confrontation of differing viewpoints that can contribute to the regulation of learning. Integrating Spelling Acquisition in Text Production Although specific instructional approaches of the M, R, and D types are still widespread in classrooms, there is increasing interest in approaches that integrate spelling acquisition in situations of text production. These approaches seek to extend to spelling the general principles that characterize process-oriented writing instruction. As proposed by Bean and Bouffler (1987), spelling should be studied in the same "functional, social, contextual" (p. 7) perspective as the writing process itself. For advocates of "whole language" instruction (McKenna, Robinson, & Miller, 1990), it goes without saying that orthographic skills are best acquired by immersion in global reading and writing activities. Other researchers adopt a more cautious position while still insisting on the importance of authentic communication situations in language instruction. For example, Jaffré (1986, 1992) considers that functional text production activities are a necessary but not a sufficient condition for mastering spelling: They provide the starting point and the overall framework for subsequent analytical activities whose goal is to extend and structure the reflections provoked by writing. Research on Integrated Instructional Approaches Relatively few empirical studies have examined methods of integrating spelling instruction in text production and the learning outcomes resulting from this instructional approach. We present findings of several recent investigations of English language acquisition in classrooms using integrated instruc-

tion as well as some conceptual contributions of recent work on French spelling instruction. In a descriptive study of classroom writing practices, Davis, Clark, and Rhodes (1994) have attempted to identify the effects of different instructional practices on student writing proficiency. Their investigation, carried out in 39 fourth- and fifth-grade classrooms, is based on three types of data: observations of classroom activities in the area of literacy instruction, interviews with teachers and school principals, and student writing samples. The data allow classification of classrooms in terms of the time devoted to extended text production as compared to time spent on exercises dealing with language conventions. Four categories of classes are established: (a) mostly exercises; (b) mixed, mostly exercises; (c) mixed, mostly extended text; and (d) mostly extended text. The results, obtained by hierarchical linear modelling, show several positive effects of instruction emphasizing extended text production (categories c and d) as compared to instruction focused on exercises (a and b). After adjustment for pretest differences at the student and classroom levels, statistically significant effects are found on two measures of student writing proficiency: a measure of the quality of writing content (ideas and text organization) and a measure of writing mechanics (syntax, punctuation, spelling). On the other hand, no significant differences between classroom categories are found when mastery of writing conventions is assessed by a standardized multiple-choice battery (Iowa Test of Basic Skills). The effects are relatively modest but, nevertheless, indicate that emphasis on extended text production is likely to foster students' capacity to write texts correctly, without diminishing their performance on standardized tests. The stability of the effects for children of different ethnic origins tends to confirm the general advantage of instruction integrating spelling and other conventions in text production. It should be noted, however, that extended text is defined in this investigation by a minimal criterion (i.e., a text consisting of several lines written with some student autonomy and initiative). It is difficult to know whether the observed effects would be accentuated (or, on the contrary, reduced) in the case of longer and more complex forms of text production. Furthermore, as stated by Davis et al. (1994), classroom emphasis on extended text is not a homogeneous category but "a marker for a complex web of interactional and instructional variables" (p. 565) that the research methods they applied were not able to untangle. Needels and Knapp (1994) went further toward the proposal of principles that could guide integrated spelling instruction. They discuss the possible advantages and limitations of a skill-based perspective involving drill and practice on each component skill of written expression; they also point out the lack of empirical validation of the claims of the whole language perspective.

Their own proposals belong to a third perspective: a sociocognitive framework for writing instruction inspired by the work of Vygotsky (1978). They define six dimensions of classroom instruction based on this approach: (a) integrating component skills within the context of the writing task, (b) using meaningful and authentic writing tasks, (c) linking writing to the child's background and experience, (d) encouraging peer interaction, (e) approaching writing as a problem-solving process, and (f) providing ample opportunities to write extended text. Writing instruction in 42 fourth- and sixth-grade classes is analyzed on the basis of data from teacher logs, classroom observations, and interviews with teachers. Each teacher's practices are rated according to their degree of coherence with each of the six pedagogical variables associated with the sociocognitive approach to writing instruction. Methods of hierarchical regression analysis are used to test the effects of these variables on two measures of student writing: writing competence and writing mechanics. The results show that the six pedagogical variables account for more than 40% of the variance in student writing competence but do not account for the variance in writing mechanics. In other words, when instruction is based on the sociocognitive model, student texts have better compositional qualities, without any decline in conventional correctness. Of the six pedagogical variables entering into the regression analysis, the strongest predictor is the relation of writing to student background and experience. Although the results do not show that an integrated instructional approach leads to improved spelling acquisition, they can at least reassure teachers who fear that decreased emphasis on traditional exercises will invariably cause a decline in spelling skills. Qualitative studies conducted by teams of French researchers and teachers (see issue 75 of the journal Repères, 1988) suggest several pedagogical strategies that might be used in integrated spelling instruction. As proposed by Jaffré (1986) and Ducancel (1988), two types of follow-up activities can be carried out after text production: (a) deferred activities in which explicit, systematic treatment is given to spelling problems encountered during writing, and (b) detached activities aimed at knowledge conceptualization through analysis and manipulation of well-chosen examples. Although these tasks are similar to those typically proposed in the R approach, their utilization remains linked to the preceding text production situation or prepares the way for a new writing situation allowing rapid reinvestment of acquired knowledge. In order to foster orthographic problem solving during drafting and during revision, analogical reference tools are developed on the basis of common difficulties encountered by students (Lartigue & Djebbour, 1988). In addition, attempts are made to define the role of student-teacher interactions and of peer interactions as a means of regulating learning (Bled, 1988; Sandon, 1988).

In an ongoing research project in Geneva,3 we are studying the implementation and the effects of an approach integrating spelling acquisition in text production in second-grade classrooms and sixth-grade classrooms. Our approach draws on previous research concerning four related topics: relationships between reading and writing in the beginning elementary grades (Rieben, 1993), self-regulation processes in text production (Allal, Michel, & Saada-Robert, 1995), analyses of student spelling errors and representations (Bétrix Köhler, 1995), and strategies of spelling instruction (Berset Fougerand, 1993). Our approach is similar in its general conception to the sociocognitive perspective defined by Needels and Knapp (1994). The field work is based on a quasi-experimental design allowing comparison of two groups of matched classrooms that apply contrasting instructional approaches during an entire school year: spelling acquisition integrated in text production versus specific instruction emphasizing exercises and dictations. The effects of instruction are analyzed by pretest-posttest measures on three tasks (exercises, text dictation, text completion). In addition, the reinvestment of orthographic knowledge and skill is studied in a more complex narrative text production situation taking place at the end of the school year. Data analysis is still in progress, but the principles underlying the integrated spelling approach can be briefly presented. Eight text production situations have been prepared for each grade level. In each situation, two spelling objectives are targeted. The choice of the objectives is linked to properties of text structure that provide a functional context for learning: for example, in sixth grade, determiner-noun-adjective agreement is worked on in the context of descriptive text production, whereas verb conjugation in the imperfect and past definite tenses is dealt with in narrative text production. Each text is written in an authentic communication perspective for an audience inside or outside the classroom. Mastery of the targeted spelling objectives is fostered by the regulations resulting from student interactions during writing and by deferred or detached follow-up activities. Figure 8.2 presents the three phases of each instructional situation and the principles associated with each phase. Comparison of Specific and Integrated Instructional Approaches Approaches integrating spelling acquisition in text production do not yet constitute a well-recognized instructional option validated by long-term empirical research in the classroom. We attempt, nevertheless, to describe the 3 This study is partly funded by a grant from the Swiss National Scientific Research Fund.

Principles 1. Before text production
Define the communication setting: - aim and audience, - type of text (e.g., description, narration, dialogue, cooking recipe).
Create a functional communication situation by defining the rhetorical constraints and the characteristics of the intended text.
Plan the content to be dealt with: collective discussion enumerating ideas and lexical items likely to be used in writing the text.
By preliminary content planning, decrease the cognitive load required for the generation of ideas during writing, and thereby facilitate the students' focus on sentence transcription, including spelling.
Present the targeted spelling objectives and specify the corresponding reference tools.
Establish reference criteria for the regulations intervening during and after text production.
2. During text production Implement different means of regulating writing, based on the student's interactions: - with the teacher, - with other students, - with instructional tools.
Foster the development of spelling skills that are fully integrated in the processes of drafting and text revision. Enhance (across 8 successive production situations) the progressive internalization of self-regulation strategies.
3. After text production Carry out various text-based activities: analysis, classification and reflection based on excerpts from student texts and on other supplementary material (specific exercises if needed).
Use deferred and detached follow-up activities to consolidate students' spelling skills; differentiate the tasks according to student needs.

An instructional approach integrating spelling acquisition in text production. overall orientation of these integrated approaches (hereafter abbreviated as I approaches) as compared to that of the specific M, R, and D approaches (hereafter grouped as S approaches) with respect to the four features of our conceptual framework. Didactical Transposition. S approaches imply the transposition of specific components of knowledge concerning the conventions of written language. I approaches entail a more complex process of transposition involving not only orthographic knowledge but also the multiple levels of semantic, syntactic, and discursive knowledge required for text production. Analysis of all aspects of this process is beyond the scope of this chapter, but two brief remarks can be made. First, implementation of I approaches requires teacher education that articulates the different areas of literacy instruction and links them to general strategies for regulating learning-teaching pro-

cesses in the classroom. Second, given the complexity of the contextualized knowledge the student is supposed to acquire, it is necessary to plan a well-coordinated curriculum sequence covering first grade through sixth grade in order to assure that functional spelling skills do in fact become an integral part of writing competence. Contextualization. I approaches are designed to promote contextualized learning as advocated in contemporary research on situated cognition. The goal is to help students construct spelling knowledge in classroom settings that are close to the out-ofschool conditions in which knowledge is to be activated and used. Rather than the transfer of knowledge from a learning situation to a context of future use, I approaches aim at learning in context from the outset. In this respect, they differ clearly from S approaches that promote skill acquisition outside of any meaningful communication setting. Cognitive Load. By proposing structured tasks involving a limited number of elements, S approaches (at least of the M and R types) attempt to facilitate the learner's management of cognitive load. Because I approaches are highly contextualized, the complexity of task elements and relationships tends to accentuate the cognitive load of the operations to be carried out. Advocates of I approaches believe, however, that learning to manage the cognitive load of complex tasks is a goal that should be explicitly dealt with in the classroom. Instructional design can attempt to restrain certain factors that contribute to cognitive load without transforming other essential parameters of a complex task. In our ongoing study, for example, we maintain the functional communicative purpose of the writing situation, but we have the students plan text content before beginning to write so that they can subsequently concentrate on sentence generation and spelling. Moreover, by learning to make use of various tools (reference books, techniques of proofreading), students can progressively acquire techniques for managing the multiple task elements more efficiently. Regulation of Learning. Depending on how S approaches are implemented, they can include various types of regulations resulting from the student's interaction with the teacher, with peers, or with instructional material. I approaches also make use of these means of regulation but attribute particular importance to the development of self-regulation through the internalization of strategies and tools initially embedded in a network of social interaction. Instruction is designed to develop not only cognitive skills in writing and in spelling but also students' metacognitive competence in managing relationships among task components.

Toward the Coordination of Specific and Integrated Approaches? In conclusion, we wish to raise the question of possible ways of coordinating the two types of instructional approaches dealt with in this chapter. Although the theoretical principles underlying S and I approaches differ, in classroom practice it may well be useful to seek ways of articulating aspects of each. The effectiveness of S approaches for the acquisition of word knowledge has been demonstrated in a sizeable number of studies. Although available research provides relatively limited validation of I approaches, the potential usefulness of these approaches seems obvious when dealing with grammatical aspects of spelling, particularly inflectional morphology in French, and when attempting to assure that contextualized spelling skills become an integral part of student writing competence. Coordination of specific and integrated approaches could be sought in two directions. When applying an integrated approach, it is possible to insert modules of specific instruction at regular intervals and thereby reinforce the acquisition of lexical knowledge. Conversely, after having applied a sequence of S modules, it is possible to introduce a situation of integrated instruction designed to consolidate specific skills in a meaningful writing context. Further work is needed in both of these directions to judge their relevance for classroom practice. References Allal, L., Michel, Y., & Saada-Robert, M. (1995).

Chapter 9 Spelling and Grammar The Necsed Move Terezinha Nunes University of London Peter Bryant University of Oxford Miriam Bindman University of London The Phonological Connection and its Limitations It is widely accepted that it takes children a long time to learn how to read and spell. Most current hypotheses about children's reading, such as those of Frith (1985) and of Marsh (Marsh & Desberg, 1983; Marsh, Friedman, Desberg, & Saterdahl, 1981; Marsh, Friedman, Welch, & Desberg, 1980) asserted that children's knowledge of written language increases right through their school years and that their approach to it changes quite radically as they become more knowledgeable. Yet, by far, the largest part of the remarkable body of recent research on children's reading has concentrated on its beginning stages, and very little of it has dealt with the considerable learning that children still have to do later on. The reason for this concentration on beginning reading is the striking success of research on one aspect of learning to read and write. The data that we now have on the early stages of reading are rich and varied in detail, but put together, they lead to one general and inescapable conclusion, which is that children's phonological awareness and phonological abilities play a crucial part in learning to read. There is ample evidence now that children have to be able to analyze the sounds that make up words and
< previous page
page_151
next page >
< previous page
page_152
next page > Page 152
syllables in order to begin learning to read, that their awareness of these sounds is a contributory factor in learning to read and write, that extra teaching in breaking words up into their constituent sounds and connecting these sounds to alphabetic letters and to sequences of alphabetic letters improves their reading, and that children who are slow to learn to read are often also particulary insensitive to the sounds in words. Much of the work on the importance of children's phonological awareness, as it is usually called, is described in other chapters in this book, and it has been amply reviewed elsewhere (Goswami and Bryant, 1990; Perfetti, 1985). We mention it now only to show why the early stages of reading have been given so much prominence in recent research. The phonological connection is at its most important when children are first introduced to the alphabet. The reason why children must analyze the sounds in words is that alphabetic letters represent those sounds. Unless children can break up words and syllables into their constituent sounds, they will not understand how the alphabet works because it works by representing those constituent sounds. That beginning readers learn about this representation and use it in ingenious and often quite original ways is dramatically demonstrated by the interesting work on invented spelling. This work shows that young children (usually in the 4- to 6-year age range) do begin to apply letter-sound correspondences when they write words, and that they get progressively better at doing so as they grow older and more experienced. Early spellings are characterized by a strong tendency to literal phonetic transcriptions. Examples are easy enough to find. Here are some from Charles Read's (1986) excellent book on the subject: ''kwyit'' for "quiet," "wrx" for "works," "sowemig" for "swimming," "wodr" for "water," "halpt" for "helped," "watid" for "waited," "wotid" for "wanted." These spellings are ingenious, but they are, of course, wrong in the conventional sense. However, there is more than one reason for this departure from conventionality, and it is extremely important to see what these reasons are. In some of these examples, the children concerned did not manage to get the phonetic transcriptions completely right. The missing vowel in "wrx," the wrong vowel in "halpt," and the missing consonant in "wotid" are all typical examples of phonetic mistakes that children make when applying the alphabetic, letter-sound correspondences that they have so recently learned. We know that children often make these kinds of phonetic mistakes in the early stages and that this sort of error declines during the early period. As they read and write more, their use of letter-sound correspondences in the literal sense gets better and better. There is, however, another kind of error in these invented spellings that no amount of improvement in phonetic transcription will ever remove. In written English and in many other orthographies, there are conventional
< previous page
page_152
next page >
< previous page
page_153
next page > Page 153
spellings for the morphemes which tell us about the grammatical status of the words, and these conventional spellings often do not accord with letter-sound correspondences. The ending of plural nouns is usually spelled with an "s" despite the fact that this "s" often represents a /z/ sound. The ending of regular past tense verbs is spelled as "ed," and yet this spelling sequence sometimes represents /d/, sometimes /t/, and sometimes /id/. Figure 9.1 presents an entirely representative piece of writing by a 7-year-old child that demonstrates quite clearly that she doesn't have any idea about how to write the final morpheme in regular past tense verbs. Plainly she has not yet learned about the "ed" sequence and nor, as we shall show, have most English children younger than 8 years of age. It is easy to see why they have not. These regularities are tied to grammar, not to phonology. Nowadays, we do not pronounce the ending of any words as /ed/, and our reasons for spelling these endings as "ed" are entirely grammatical. We end the written word "helped" with an "ed" precisely because it is a regular past tense verb, and we do not end the written word "abrupt" in the same way precisely because it is not a past tense verb. Surely children must learn about this grammatical connection in order to be certain that the ending of ''helped'' is spelled in one way and of "abrupt" in another. These simple, almost obvious, observations clearly lead to a new hypothesis, which is that children first have to conquer the phonological connection and then the grammatical connection in written language. First they have to learn about the relation between sounds and alphabetical letters and sequences of letters: Next they must conquer the relation between each word's grammatical status and the way that it is spelled. What then is already known about the grammatical connection? The Grammatical Connection and The Idea about Context Although the phonological connection has been at the center of recent research on children's reading, the idea that grammar might be important has also received a fair amount of attention. However, this interest in the possibility of a grammatical connection was almost always prompted by concerns that are quite different from those that we set out in the previous section. As far as we can discern, the driving force behind work on the possible importance of children's grammatical knowledge in learning to read is the notion of the psycholinguistic guessing game. The phrase is Kenneth Goodman's (1982) and it encapsulates the idea that children use the context of the passage that they are reading in order to guess the meaning of any difficult words in it. Contextual cues can take several different forms semantic, syntactic, or pictorial, for example and the possibility that children's

sensitivity to syntax might be important has led several researchers to devise tests of syntactic awareness and then to relate children's performance in these tasks to the progress that they had made in learning to read. This line of research has scored some notable successes. It has consistently been found that children who score poorly on such tasks are likely also to make slow progress in learning to read (Rego & Bryant, 1993; Tunmer & Bowey, 1984; Tunmer, Nesdale, & Wright, 1987), and it is now clear that there really is an interesting connection between children's syntactic awareness scores and their ability to use the context to help them decipher the meaning of difficult words (Rego & Bryant, 1993). We should like to make two points about this line of research. One is that there is a great deal of uncertainty about what syntactic awareness tasks actually measure. For example, one of the tasks used in this research is a sentence anagram task in which children have to make meaningful sentences out of words spoken to them in a jumbled order, and another is a cloze task in which children hear a sentence with a missing word and are asked to fill the gap. Both these tasks, as Gombert (1992) and, subsequently, Bowey (1994) have argued, make semantic as well as syntactic demands, and are not therefore pure tests of syntactic awareness. The second point is that there is a considerable difference between the grammatical knowledge that is at stake both in these tasks and in Goodman's hypothesis and the grammatical knowledge that we ourselves wrote about in the previous section. Sentence anagram tasks and cloze tasks deal with the structure of the sentence; we, in contrast, are concerned with the spelling of morphemes. Sentence anagram and cloze tasks measure, for example, children's knowledge that a definite article is usually followed by a noun or by an adjective and then a noun and never by a verb. In contrast we are speculating, for example, about the difficulties that children might have in understanding why the last sound in kissed is spelled "ed" and not "t". There is no conflict between the two approaches, and the hypotheses guiding them might both be right, but they are quite different from each other. It is time to say what our own hypothesis is. Syntactic Awareness and the Spelling of Morphemes Our Hypothesis and How to Test it The hypothesis that we adopted at the start of our research was that there is a definite stage at which children come to grips with the spelling of morphemes and that this new development is based on their grammatical or, more specifically, on their morphosyntactic awareness. Children have to understand that some words end in "ed" because they are past tense
< previous page

page_156
next page > Page 156
verbs, that some words begin with "wh" because they are interrogatives, that some words end in "'s" because they are singular possessives, and others end in ''s''' because they are plural possessives. Just as the earlier learning about letter-sound relationships depends to a large extent on the children's awareness of phonological distinctions, so this later learning depends on their sensitivity to grammatical distinctions, a sensitivity that we call morphosyntactic awareness. Our hypothesis also raises the question of the origins of this form of linguistic awareness that we deem to be so important. It could be the result of children's informal linguistic experience outside the classroom, or it could be the direct result of being taught to read and to spell. In this chapter, we present no evidence on this particular question, though we think it an important one. However, we think that the first step is to establish whether there is a connection between this kind of lingusitic awareness and children's success in learning the conventional spelling of morphemes, and that is the step that we try to take here. It is easy to see that any test of this hypothesis has two predictions to test: The first is that there is a developmental shift from learning about letter-sound correspondences to learning how to represent grammatical distinctions in writing, and the second is that this later form of learning is based on children's grammatical awareness. The best test of any hypothesis about a developmental sequence is a longitudinal study because it shows not only that older children behave differently from younger children but also that such differences are to be found in the development of individual children: Longitudinal research demonstrates that individual children progress from one way of behaving to another. Another advantage of longitudinal work is that it can provide a plausible test of the idea that learning how to spell morphemes is heavily influenced by children's morphosyntactic awareness. If this is true, measures of this sensitivity taken in one session should be strongly related to the subsequent progress that children make in spelling morphemes. We devised a 3-year longitudinal study to look at children's spelling of morphemes and also at their morphosyntactic awareness and to track the relation between the two. The children 363 at the outset of the project were 6, 7, or 8 years old the first time that we saw them. In this chapter, we describe some of our results in the first year of the project, and so the ages that we are dealing with are 6, 7, 8, and 9 years. In the spelling tasks, we concentrated on past tense verbs. Several times during the first 2 years, we asked the children to write for us the words that are presented in Table 9.1. Our list consisted of two kinds of past tense verbs: regular ones with the "ed" spelling (e.g., kissed), and irregular ones whose ending is spelled phonetically (e.g., felt). Each of these types was divided into two those ending in a "t" sound when spoken and those ending

How What When Where Which Who Why in a "d" sound. In addition, we included words that ended with a sound similar to the past tense verbs in our list, but they were not past tense verbs. This made six categories, and our idea was that there were markedly different patterns in the way that children spelled these different kinds of words at different ages. At first, they spelled them phonetically, later they introduced the conventional "ed" spelling, particularly with past tense verbs, and finally they learned that there are some exceptions to the rule that past verbs end with an "ed'' spelling. In addition, we included some interrogatives, most of which began with a /w/ sound (the exceptions were "who" and "how") and in their written form started with the "wh" spelling (the exception is "how") because they

are another example of the spelling of a sound depending on the grammatical status of the word that the sound is in. Of course, it is always possible that children could learn the right spellings for interrogatives by rote because there are so few of these words. However, if we were to find a particularly strong connection between children's success with these words and with past tense verbs, we could conclude that the two sets of words are learned in the same way and that the connections are due to both sets of spellings having a grammatical basis. Our main syntactic measures were new. Because our hypothesis was that children's spelling of these morphemes depends on their awareness of differences in parts of speech (past tense verbs versus nonverbs and interrogatives versus noninterrogatives), we needed tasks that measured this kind of awareness, which we have called morphosyntactic awareness, quite specifically. We devised two new tasks of our own, and for a third we used a pseudoword technique originally devised by Berko (1958). The three tasks are presented in Table 9.2. Both our tasks took the form of a series of analogies. In the sentence analogy task, we spoke a sentence and then spoke exactly the same sentence except that the tense of the verb was changed: The change was either from present to past tense or from past to present. Then we spoke another sentence in which the tense of the verb was the same as the first of the original two sentences and asked the child to carry out exactly the same transformation on this new sentence. We wanted to see if the child could make the same change in tenses as we had. In some of the trials, we used regular past verbs and in others, irregular ones.

The word analogy task took a similar form except that we used single words (where we had used whole sentences in the sentence task), and the range of grammatical transformations was greater. Some involved past verbs, and others involved different aspects of grammar. Our third specific test of children's morphosyntactic awareness was a pseudoword task. This was an adaptation of Berko's (1958) justly famous task, which seems to us to be a direct and simple way of measuring children's awareness of grammatical distinctions. We gave children pictures and in describing these pictures, we introduced pseudowords. Then we asked children questions that required them to transform these new nonverbs by adding a morpheme. Two trials dealt with singular to plural transformations ("This is a picture of a ZUG; here is another picture and there are two of them in it. There are two ____?"). In 5 of the trials, the transformation involved present and past tenses ("This is a picture of a man who knows how to MAB. He is MABBING along the street. Yesterday he did it too. Yesterday he ____?"). Finally, we tested the children's IQ, and we gave them standardized tests of reading and spelling. In this chapter, we confine ourselves to the data that we gathered on the first occasion when we saw the children and on a following occasion 6 months later. We organize the data from these two sessions around the two questions that we posed in the previous section: The first of these is the developmental question (Do children first spell phonetically and later learn the conventional spelling of grammatical morphemes that are not clearly represented phonologically?), and the second is the causal question (Is the later form of spelling based on children's grammatical awareness?). The Developmental Question The Stages and the Data To answer the developmental question, we looked first at the existence of certain kinds of misspellings of the endings of words. If our idea that children originally spell phonetically and pay no attention to grammatical distinctions is right, there should be a considerable number of phonetic spellings ("kist" for kissed). We also predicted that when children initially learn that past verb endings are spelled as "ed," they apply this liberally to irregular past verbs as well as to regular ones; therefore, there should also be several generalizations ("sleped'' for slept). We also argued that phonological spellings should be more typical of younger children and generalizations more typical of older children. We found these two kinds of mistake in profusion in our data (as Table 9.3 shows), and our developmental hypothesis was bolstered by the fact that although the phonetic transcriptions decline between 7 and 8 years of age, the generalization of the "ed" sequence to irregular past tense verbs actually increases as children get older.

The figures in parentheses are standard deviations. We also frequently found another, much more surprising kind of error, which we called overgeneralization (and which, in truth, did not surprise us at the time, for we had found it before in some pilot work). This took the form of children sometimes spelling the endings of nonverbs as "ed" ("sofed" for soft, "necsed" for next and "ground" for ground). This particular mistake was less common than the other two kinds, but it was frequent enough and widespread enough to merit a great deal of attention. Why do some children apply the conventional, but unphonetic, spelling for past tense verbs to words which are not verbs at all? When we tried to answer this question, we used as a starting point the fact that these errors apparently increase and then decrease with age as Table 9.3 shows. This suggests an intermediate stage somewhere between phonetic spelling and grammatical spelling. The idea we arrived at was that there is a time when children who have learned to use letter sound correspondences become aware that these are sometimes violated and that one such infringement is that some words,

page_161
next page > Page 161
which end in the /d/ or /t/ sound, end with an "ed" spelling in their written form. The children realize this, but they do not at first understand the grammatical significance of the "ed" spelling, so they attach it to nonverbs as well as to past verbs. They are genuinely at an intermediate stage too late for simple phonological spelling and too early for syntax. When we included this last idea, our developmental hypothesis took the form of 5 developmental stages, which are summarized in Table 9.4. The first is a prephonetic stage; we put this stage in our scheme because the first scan of our data showed that many of the children, particularly the younger ones, failed to represent the endings of the words that they were given in any consistent or comprehensible way. The second stage is the phonetic stage, which we have mentioned a great deal already, in which the main characteristic is spelling all the endings, past tense verbs included, phonetically. Children in this stage either never write the "ed" ending appropriately or inappropriately, or write it very scarcely. Thus, our criterion for assigning children to this stage is that they make a reasonable number of phonetic transcriptions at the ends of words but do not resort to the "ed" ending or do so very infrequently. The third stage is the intermediate stage in which children begin to use the "ed" ending, thus demonstrating that they are using more than just phonetic correspondences but failing to see its grammatical basis. Thus, they write soft as "sofed" as well as slept as "sleped." These children are not consistent in their use of the "ed" spelling. They use it sometimes but very often spell phonetically instead. Our criterion for this stage is that children write ''ed''s at the end of words but sometimes do so to nonverbs. In the fourth stage, the children realize that there is a grammatical basis to the "ed" ending and put it only at the ending of past tense verbs. However, they generalize this ending to irregular verbs as well. Children in this stage

are much more consistent in using the "ed" spelling with past tense verbs. They produce far fewer phonetic spellings than children in the previous stage. This means that our criterion for assigning children to the fourth stage is that children write the "ed" ending reasonably frequently and restrict this ending to past tense verbs but do so with irregular verbs as well as regular verbs. We should like to add here that the transition from earlier stages to the fourth stage is the most important change because this is when the children recognize for the first time that there is a connection between grammar and spelling. Children in the fifth and final stage write the "ed" ending at the end of regular past verbs only and return to writing the end of irregular verbs phonetically as they used to in the second stage. These children restrict the "ed" ending to regular past tense verbs and do not generalize this spelling sequence to either irregular verbs or nonverbs. In chapter 15, Rieben and Saada-Robert conclude that it is extrememly difficult to assign chidren to developmental stages in reading. We did not find this to be so, as the results we report demonstrate quite clearly. There are various possible reasons for this difference between Rieben and Saada-Robert's efforts and our own. One is that they are concerned with hypotheses about reading strategies such as the logographic and alphabetic strategies, which may well occur at the same time and at a very early stage in reading. We, on the other hand, are dealing with two forms of knowledge the connection between phonology and spelling and the connection between grammar and spelling that probably come into play at very different times in the process of learning to read. Indeed our hypothesis, clearly supported by our results, is that there is a gap of up to 2 years between the time when children apply letter sound correspondences to their spelling and the time when they grasp the grammatical basis for various spelling sequences. Another possible reason for the difference between our relatively optimistic conclusion and Rieben and Saada-Robert's relatively pessimistic conclusion about stages in learning to read and spell may be their insistence that the stages should be mutually exclusive, in the sense that a child using a strategy characteristic of one stage should not at the same time adopt another strategy that characterizes another stage. To some extent, our model demands this to be so and to some extent it does not. It is an essential part of our hypothesis and of the objective criteria that we adopted that children in Stage 5 should make no generalizations at all about past tense verbs or nonverbs (the characteristic patterns of Stages 3 and 4) and that children in Stage 4 should make absolutely no generalizations for nonverbs (the characteristic strategy of Stage 3). To that extent, the strategies that children use in our stages are mutually exclusive. However, our model is more relaxed about inappropriate phonetic transcriptions, the characteristic

next page > Page 163
pattern of Stage 2. We did not expect children to stop making these mistakes at the time when they began to adopt the "ed" ending, and they certainly did not. Our model accepts and even promotes the idea that children may continue to overuse letter sound correspondences because letter sound correspondences continue to be and will always be an essential part of spelling. Here, our model of children's development is an additive one. We do not think that children abandon letter sound correspondences in spelling when they reach our Stage 3. That is an absurd idea. We simply argue that children eventually begin to add to this strategy a new one that is based on the recognition of spelling sequences that are not literal phonetic transcriptions and that are based on grammar. So, we were prepared to accept inappropriate phonetic transcriptions made by children in Stages 3, 4, and 5, and we found them, although to a decreasing extent as the children ascended our developmental ladder. Our quite precise, developmental hypothesis produced two predictions that could easily be tested in our large-scale longitudinal study. The first is that it should be possible to assign all, or at least nearly all, of the children quite unambiguously to one of these 5 stages on the basis of the way that they spelled the words presented in Table 9.1.1 The second is that when children change from one stage to another over time, the change should be upward on our developmental scale and not downward. When we assign the children to stages in two different sessions, the first session and a following one 6 months later, the children should be either at the same stage in both sessions or at a higher stage in the later session. Our developmental hypothesis demands that individual changes over time should be in one direction but not in the other, and our longitudinal data allows us to test this prediction in a most stringent manner by plotting each individual child's position in our sequence of stages in the first session and in the next one 6 months later. To test the first prediction, we objectively assigned children to stages on the basis of our criteria (given in Table 9.4). In fact, a computer did it for 1 When we set the criteria for our stages, we decided that in order to be placed in Stages 2 to 5, children had to demonstrate that they knew the alphabetic rules. Therefore, the requirement was that all the children in these stages had to be able to spell half of the endings that were phonetic transcriptions (i.e., the endings of the nonverbs and irregular verbs). If they could not manage that, children were categorized as prephonetic and assigned to Stage 1. Children assigned to Stage 2, the phonetic stage, made at least five inappropriate phonetic transcriptions of regular past tense verbs (e.g., "killd" for killed) and also produced very few (less than three) "ed" spellings. For Stage 3, the stage when children begin to produce the "ed" spelling without understanding its grammatical basis, children had to write at least three ''ed" endings. However, at least one of those was a grammatically inappropriate generalization to a nonword. Our joint criterion for Stages 4 and 5 was still that children should produce at least 3 ''ed" spellings, but these spellings had to be only for past tense verbs. Children who generalized the spellings to irregular verbs were placed in Stage 4, whereas children who wrote "ed" endings for only regular past tense verbs were assigned to Stage 5.

us because we wrote the criteria, given in footnote 1, into the program that selected the children for the different groups. In both sessions, we found that very few children did not meet the criteria for any of the stages. In the first session, 92.8% (337 out of 363) of the children and in the next session, 95% (307 out of 323) of the children were easily assigned a position in our sequence of stages.2 Our notion that these stages are developmental was supported by the fact that as Table 9.5 shows, there was a direct relationship between the stage that the children were assigned, according to our scheme, and their ages as well as their scores on a standardized reading test. The higher the stage, the older, on the whole, the children were and the more advanced at reading they were. Our second prediction was also confirmed. Table 9.6 shows that the majority of the children conformed to our developmental hypothesis. In fact, 87.7% of the children either stayed at the same stage over the two sessions or were at a higher stage in the second session than in the first. Of the children who were at different stages in the two sessions, many more were at a higher stage after 6 months than they had been in the first session: 34.7% changed in the direction that was right, according to our hypothesis, and only 12.3% changed in the wrong direction. The existence of the relatively small number of backsliders is awkward for us, but it may be due to these children being held back by extraneous problems. At any rate, the marked trend for children to move up rather than down our developmental ladder is strong support for our developmental hypothesis. 2 We also found that many of the 26 children who could not be classified in our stages tended to spell the endings of regular verbs that we had designated as ending in /t/ (e.g., learned) as "d" (e.g., "learnd"). It could be argued that these spellings should be treated as phonetic transcriptions too. When we analyzed all ''d" or "t'' spellings at the ends of words as phonetic transcriptions, we found that 14 of the 26 excluded children were now classified as being in Stage 2 the phonetic stage. However, for our main analysis we decided to stick to a strict criterion for phonetic spellings (i.e., only "t"s for words ending in /t/ sounds and only "d"s for words ending in /d/ sounds).

We should like to mention one other result that provides extra support for our idea that children come to grips with the grammatical basis of certain spelling sequences during this period. The scores for spelling the "wh" sequence at the beginning of interrogatives were rather low, but there was a very strong relationship (r = 0.74) between children's success in writing the "wh" sequence and writing the ''ed" sequence at the end of the right words. This strong relationship held even when differences in age and in performance in a standardized spelling test were controlled in a fixed-order multiple regression; even after controls for these variables, the children's "wh'' scores still accounted for 38.3% of the variance in their "ed" scores. This connection certainly supports the idea that children learn both the "ed" ending and the "wh" opening sequence in the same way, and this way must have something to do with grammar. It looks as though the same factor or factors might govern children's progress in learning about both spelling sequences. What can these factors be? The Causal question Morphosyntactic Awareness and the Development of Spelling Our idea is that children's sensitivity to the distinction between different parts of speech is the basis for their eventual mastery of the conventional spelling of grammatical morphemes. We call this sensitivity "morphosyntactic awareness." According to this idea, there should be a strong relation between the children's performance in our syntactic tasks or at any rate in the three tasks (see Table 9.2) that specifically tested morphosyntactic awareness and the children's positions in our developmental sequence. We looked at this relation in two ways. One was to see whether children at different stages in our developmental sequence of spelling also scored differently in the syntactic tasks. The other a more stringent prediction
< previous page

next page >
< previous page
page_166
next page > Page 166
was to establish whether children's scores in the syntactic tests in the first session predicted whether they would improve their position in the stage sequence by the time they were tested in the following session. Table 9.7 gives the scores for the three syntactic tasks that specifically deal with the distinction between different parts of speech. The table presents the mean scores for the children in the different stages. It shows that in all three cases, there was a regular relation between the stage the children were at in spelling the verbs and nonverbs and their scores on the syntactic awareness tests. The higher the stage, the higher was the performance in the syntactic task. It could be argued that this was just a function of age because there was also a direct relationship between age and the stage assigned to the different children, but with each of the three tasks, the relationship remained significant when age differences were controlled in an analysis of covariance. Another result of these analyses of covariance was that in every case, there was a significant difference on posttests between the children in Stage 3 and those in Stage 4. This is an important result as far as we are concerned because the transition from Stage 3 to Stage 4 is a particularly important one. According to our scheme, it marks children's realization of the connection between grammar and spelling. Strong as these relationships within sessions are, relationships across time are more persuasive when it comes to testing causal hypotheses. Our specific prediction concerned children who were at the same stage as each other in the first session but progressed at different rates after. Our prediction was that the children's scores in the syntactic awareness tests in that first session be related to the amount of progress. Those who moved to a higher stage should have started with higher scores in the syntactic tasks than those who stayed where they were. In particular, we predicted that those who made the shift from Stage 1, 2, or 3 (pregrammatical) to Stage 4 or 5 (grammatical) should have scored higher on the syntax awareness tasks in Session 1 than those who remained in the pregrammatical stages.

The figures in parentheses are standard deviations. Table 9.8 presents the results of this comparison. It shows that, in all three tests, the children who advanced from a pregrammatical stage at Time 1 to a grammatical stage at Time 2 had done better in the syntactic awareness task at Time 1 than those who remained at a pregrammatical level. These differences between those who advanced and those who did not were significant in each case and remained so in analyses of covariance in which the children's initial stage in the first session was entered as a covariate. This means that these tests do predict who, later on, will make progress to a higher level of spelling and who will not. Conclusions and Suggestions The evidence that we have presented supports the idea of a developmental sequence in learning about written language that is heavily influenced by children's sensitivity to spoken language and that probably stretches into late childhood. First, children have to learn about letter sound correspondences, and this learning is heavily dependent on their phonological awareness, but as they encounter a wider range of words and spelling patterns, they realize that there is more to spelling than the phonological correspondences that they have tried to master so far. They begin now to adopt new spelling patterns such as the "ed" sequence but with scant regard for the grammatical basis of this sequence. Later on, they learn how to apply the "ed" spelling to the correct grammatical category and, later still, they conquer the exceptions. Their learning of the grammatical connection largely depends on the strength of their grammatical awareness. We have concentrated on one highly specific instance of this second kind of learning the understanding of the "ed" spelling pattern but there are
< previous page
page_167
next page >
< previous page
page_168
next page > Page 168
other examples in English that should be studied now. One is the "wh" sequence, which we have mentioned briefly and which children conquer at roughly the same time as the "ed" pattern and in much the same way. Another is the use of the apostrophe to signify possessives a striking instance of spelling indicating a grammatical relation. We have also gathered data in two pilot studies and in our longitudinal project on children's learning the significance of apostrophes. These data still need further analysis, but we already know that even 12-year-old children are often completely ''at sea" with the grammatical basis for apostrophes. This supports our claim that learning about the grammatical basis for spelling continues for most of the school years. Learning to read and to spell English is a long business, and we need to know about the whole of this business and not just its early years if we are to ensure that every child is literate by the time that he or she leaves school. We also assert that it takes children learning other orthographies a great deal of time to learn about the grammatical basis of spelling patterns. In most European languages, as well as English, one can find the phenomenon of the same sound being spelled in different ways depending on the grammatical or lexical status of the word that the sound is in. In Portuguese, for example, there are several phonological sequences that have alternative spellings, only one of which will be correct for certain classes of words. The phonological sequence /ozu/ may be spelled as "oso" or "ozo" and the pronunciation of these two spellings is indistinguishable. However, the spelling sequence "oso'' is a derivative morpheme that can be attached to nouns to generate adjectives; adjectives ending in the phonological sequence /ozu/ will only be spelled as "oso." Nunes (1992) observed that firstgrade children (age 7) have a preference for using "z," which is the letter they initially learn to represent this sound. However, the letter S between two vowels is always pronunced as /z/ in Portuguese, and children discover soon enough that the sound /z/ may be represented by "s" or "z," without much awareness of either the phonological or the morphological contexts that allow for the discovery of consistency. In spite of the complexity of the spelling rules, it is possible to observe some consistency in children's progress in spelling of the phonological sequence /ozu/. Children start out using "z" to represent all the /z/ sounds, including all instances of /ozu/. Then they use "s" also to represent the /z/ sound, but no particular pattern for this use can be discerned at first. However, in fourth grade, the probability of children spelling the /z/ sound with "s" in pseudoadjectives formed by adding the suffix to a real noun was greater than that of spelling with "z," although errors were still observed at this age. In French, too, grammar plays a crucial role in spelling. Third-person singular and third-person plural verbs have identical pronunciations for the most part but are spelled very differently ("il aime" and "ils aiment," for
< previous page

page_169
next page > Page 169
example). The same is true of most singular and plural nouns. They usually sound the same, and yet their endings are spelled quite differently ("maison" and "maisons"). With both nouns and with verbs there is a written, but unspoken, plural ending. In Chapter 6, Totereau, Thevenin, and Fayol show that French children take several years to come to grips with these different endings. At first, they simply ignore the unpronounced plural endings in their writing. They write the endings of plural verbs and nouns as they sound without an "nt" or a "s" ending in just the same way as English children ignore the "ed'' ending and write kissed as ''kist." Later, they begin to put in the "s" ending for plurals, but they add it to the ends of verbs as well as to the ends of nouns. Later still they learn the "nt" ending, but instead of just adding it to verbs, they also sometimes put it at the end of nouns as well. Finally, they learn to add "nt" to third-person plural verbs and "s" to plural nouns. This developmental sequence is strikingly similar to the sequence that we have described with English children. In both languages, children do not write the grammatical morpheme if it does not fit with the grapheme phoneme correspondences that govern their spelling at the time, and in both languages, this initial phase is closely followed by a period in which children actually do include the conventional spelling for the grammatical morpheme but often place it in grammatically inappropriate words ("sofed" instead of soft in English; "maisonent" instead of "maisons" in French). Finally, in both languages, children do learn the grammatical basis for the different spellings. It is hard to resist the conclusion that this learning must be based on children's knowledge of grammar. The children are certainly using some grammar; their readiness in Stage 4, in our sequence, to spell irregular past verbs with an "ed" ending is sufficient evidence for that. They have never seen words similar to "sleped" before, and so their willingness to put "ed" endings in past verbs, regular or irregular, and not in other words, shows that they have understood the grammatical significance of "ed." Our data, however, give us more than a mere a priori case for the grammatical connection. The three syntactic tasks that we devised are strongly related to our developmental sequence, particularly with the difference in this sequence between the stages that we describe as pregrammatical and grammatical. The three tests also predict children's subsequent progress up this developmental ladder. To clinch the causal argument, we need intervention studies; we need to strengthen children's grammatical awareness and see how this affects their spelling. Inevitably, such studies raise the educational question, too. What should we teach our children about grammar? We have no ready answer to this question, and we think that the answer must wait for research on how to increase children's awareness of grammatical distinctions. That should be the necsed move.

Chapter 10 Why Spelling is More Difficult than Reading Anna M. T. Bosman University of Nijmegen Guy C. Van Orden Arizona State University Thinking is always limited by the quality of our metaphors, and this is no exception. Robert James Waller (1988, p. 116) Before you read this chapter, please get a pen and write down the name of the Indian nationalist and spiritual leader who developed the practice of nonviolent resistance that forced Great Britain to grant independence to India. He is known as Mahatma ____. Campbell and Coltheart (1984) found that undergraduates of two London colleges, despite numerous exposures through ads and newspaper articles following the release of the famous movie "Ghandi,"1 were unable to spell the name of the man who showed India the way to freedom. The chance that you spelled his name correctly is between 14% and 44%. An example from the Dutch language (the first author's native tongue) is the notorious misspelling of the word sperzieboon (green bean). The majority of people, including greengrocers, misspell the word by writing a C instead of a Z 1 Actually, the proper spelling is GANDHI. Campbell and Coltheart (1984) explained the high percentage of "Ghandi"misspellings in English-speaking college students in terms of a high summed position-specific bigram frequency of this pattern as compared to that of the correct spelling pattern "Gandhi." However, a similar test with Dutch-speaking University students showed that they had the same tendency of spelling Gandhi's name as Ghandi (21 out of 24 misspellings); Dutch summed position-specific bigram frequency, however, favors the Gahndi-pattern (Klønhammer, 1990).

(spercieboon). This misspelling is phonetically accurate but is rather unconventional. Thus, to be in a QUANDERY about the spelling of QUANDARY is not a problem restricted to children. Highly skilled writers often need a dictionary or the spellchecker of a word processor to verify a word's spelling, but for skilled readers, doubts about how to read a word are largely restricted to heterophonic homographs English examples are live, tear, and wind; Dutch examples are kantelen (topple/crenelation), regent (rains/regent), and bedelen (endow/beg for). This asymmetry between spelling and reading is evident at all levels of literacy. Skilled readers read more words correctly than they can spell, and children's spelling and reading skills diverge soon after the onset of formal instruction (Mommers, 1987; Seymour & Porpodas, 1980). It is relatively easy to find children whose reading performance meets the required level but whose performance on a spelling test is below average, whereas the opposite pattern is much more rare (Frith, 1980). Spelling problems of dyslexic readers also prove to be more persistent than reading problems (Frith, 1984, 1985; Nicolson & Fawcett, 1994; Thomson, 1984). These observations raise many interesting questions, including the general question of how spelling and reading are related. Moderate to high correlations between scores on spelling and reading tests suggest a fairly tight relationship (Malmquist, 1958, cited in Frith, 1980). This leads some theorists to emphasize the similarities between the skills, and claim that the processes (Ehri, 1980; Gough, Juel, & Griffith, 1992) or representations (Perfetti, 1992) underlying spelling and reading are, in fact, the same. Others, however, stress the differences between spelling and reading processes, suggesting two separate mechanisms (Bryant & Bradley, 1980; Frith & Frith, 1980). Frith (1979) claimed that reading occurs by "eye" and spelling by "ear" to make the point that spelling is phonologically mediated but reading is not. Read (1981) also argued that reading and spelling are not symmetrical because children who attempt to write words or stories often cannot read their own "invented" spellings (see also Treiman, 1993). The most cited empirical evidence suggesting separate mechanisms for spelling and reading was provided by Bryant and Bradley (1980). Dyslexic and nondyslexic beginning readers read words they had previously spelled. Generally, both groups read more words correctly than they were able to spell. In all groups, however, there were some words that children were able to spell but unable to read (the percentage varied between 3% and 13%). Gough, Juel, and Griffith (1992) replicated the experiment with a group of nondyslexic beginning readers. On four different occasions, their participants read each word twice and spelled each word twice. As in the study of Bryant and Bradley, the children sometimes were able to spell words they were unable to read (on average 10%). Moreover, they sometimes were able to read words on one occasion but not on the other (10%) and, sometimes, they

spelled words incorrectly on one occasion and not on the other (11%). Thus, the inconsistency observed between spelling and reading also occurred within reading and within spelling, respectively. If the inconsistency between spelling and reading merely reflects performance variability across occasions, then this inconsistency no longer motivates separate mechanisms. In this chapter, we eventually present a framework for spelling and reading that does not require independent components to explain the asymmetry between spelling and reading performance. Spelling and Phonology Since Read's publications on children's invented spellings (1971, 1981, 1986), it has generally been acknowledged that beginning (and skilled) spellers rely heavily on phonology. All theories of spelling acquisition include a dominant role for phonology (Frith, 1980, 1985; Henderson & Beers, 1980; Marsh, Friedman, Welch, & Desberg, 1980; Read, 1986; Snowling, 1994). Empirical evidence for phonology's role in spelling comes from two sources. First, phonological awareness and spelling skill are highly correlated (Bruck & Treiman, 1990; Duighuisen & van Bon, 1992; Holligan & Johnston, 1991; Lundberg, Frost, & Peterson, 1988; Marcel, 1980; Stuart & Masterson, 1992; uit de Haag, 1994; van Bon & Duighuisen, 1995). Second, spelling errors are predominantly phonetically accurate. One common definition of phonetically accurate spelling errors is that the error pattern can be pronounced identically to the intended word using grapheme-to-phoneme correspondence rules (e.g., Bosman, 1994; Bruck, 1988; Holmes & Ng, 1993; Treiman, 1993). For instance, the spelling pattern KLINTON is phonetically correct as an attempt to spell the name Clinton. Sounding out KLINTON by applying grapheme-to-phoneme correspondence rules will sound just like an American President's last name. A similar example in Dutch, sounding out the incorrect graphemic pattern VAN GOCH produces van Gogh a phonetically correct representation of a famous Dutch painter's last name. The spelling pattern PLINTON, in an attempt to spell Clinton, is considered phonetically incorrect because no grapheme-phoneme correspondence rule seems to be able to produce the intended word. This definition of phonetic accuracy has been applied to the spellings of skilled adult spellers (Bosman, 1994; Campbell & Coltheart, 1984; Gompel, Tromp, de Vries, & Bosman, 1990; Holmes & Ng, 1993; Sloboda, 1980), normal beginning spellers (Bosman & de Groot, 1991; Bosman, de Groot, & van Leerdam, 1995; Bosman & van Leerdam, 1993; Brown & Ellis, 1994; Manrique & Signorini, 1994; Porpodas, 1987; Waters, Bruck, & Seidenberg, 1985), children with spelling (and reading) difficulties (Bruck, 1988; Bruck & Waters, 1988; Frith 1984; Nelson, 1980; Valtin, 1987), prelingual deaf children and adults (Camp-

bell, 1994; Dodd, 1980; Gibson, Shurcliff, & Yonas, 1970), language-disordered children (Cromer, 1980), an adult with an acquired spelling disorder (Hatfield & Patterson, 1983), and a hyperlexic child whose spelling and reading skills were extraordinary but who performed below average on intelligence and language tests (Siegel, 1994). In all these cases, the vast majority of spelling errors were phonetically acceptable. The occurrence of phonetically correct errors is traditionally explained by a phonological spelling route, that is, phonemes are recoded into graphemes by means of phoneme-to-grapheme rules. However, there are inherent limits on a phoneme-grapheme converter. A large number of phonemes map onto more than one grapheme (e.g., the phoneme [i:] has two possible spellings as in Heap and as in Deep). Also spellers do make errors that do not qualify as phonologically correct by the previous criterion. These facts seemed to necessitate a second lexical spelling mechanism. The lexical spelling route reads out whole-word spellings. Non-phonetic errors occur when something goes wrong in the read-out process (Ehri, 1980; Holmes & Ng, 1993; Kreiner & Gough, 1990). These two routes from lexicon to print in the dual-route model of spelling production (Barry, 1994) are the mirror images of the two routes in the dual-route model for reading (Coltheart, 1978). Next, we question whether spelling errors can be reliably classified in two distinct categories. In doing so, we question the empirical justification for two spelling routes. Spelling Errors Reassessed The previous definition of phonetically acceptable errors is based on applying spelling-to-sound rules to a spelling pattern. However, both Read (1971, 1981, 1986) and Treiman (1993) showed that an evaluation of spelling errors solely based on spelling-to-sound rules seriously underestimates the phonetic complexity of children's invented spellings and the spellings of beginning readers/spellers (see also Moats, 1993). We do not address this issue in full; excellent treatments are provided by Treiman and Read. An illustration by means of examples is sufficient. Take, for instance, the letter string DIK in an attempt to spell the word dike. According to spelling-to-sound rules, this is a phonetically inaccurate spelling pattern. However, if we extend the definition and assess phonetic accuracy using the sound-tospelling relation in the other direction, this pattern becomes phonetically correct. The phoneme [ai] covaries with the grapheme I*e, as in stripe, hive, and agile, but also with I as in pint, find, bind, kind, and mind. A speller who spelled DIK on the basis of the second set of words has shown sophisticated knowledge of a sound-to-spelling relation. The same applies in Dutch. The letter string AMSTERDAMERS in an attempt

page_177

to spell the word Amsterdammers (people from Amsterdam), is a phonetically incorrect spelling pattern, given standard spellingto-sound relations, but sound-to-spelling rules render it a perfect representation of the word Amsterdammers. The majority of Dutch first graders make this mistake initially. Assessing spelling errors on the basis of both spelling-to-sound and sound-to-spelling appears to reveal more of the phonetic structure in children's (and probably also in adults') spelling attempts than just on the basis of spelling-to-sound rules. Thus, a more liberal assessment of phonetic accuracy appears reasonable. However, both the restricted and the liberal definition of phonetic accuracy assume a categorical distinction between phonetically correct and phonetically inaccurate spelling errors. The following examples show the difficulty (if not impossibility) of precisely specifying these categories. A child's misspellings in the words KELL (for bell), KALL (for ball), KUG (for bug), and KIT (for bit) appear phonetically inaccurate in terms of spelling-to-sound rules and sound-to-spelling rules, but are these spelling attempts void of phonetic knowledge? The most likely interpretation of the error pattern of this child is that she misremembered the physical shape of the letter B. After all, the (phonetic) structure in the incorrect spelling patterns is identical to the structure in the correct patterns. (These English examples are made up to illustrate patterns observed by the first author in Dutch children's spelling.). Another example illustrates why it is often necessary (and revealing) to know what a child wanted to spell to fully appreciate its phonetic complexity. For example, the letter string CINPYEUTER is an attempt by Read's son, at the age of 6, to spell the word computer (Read, 1981). To establish that a spelling error was not mediated by phonology, it is necessary to fully recover the intention of the speller (see also Moats, 1993), whereas establishing that a spelling error was mediated by phonology appears uncontroversial. This practical impossibility of sorting errors into two distinct categories bears on theoretical issues because this distinction is the sole basis for proposing two spelling mechanisms. The previous examples do not imply that meaningful assessment of spelling errors is impossible. A less theoretically driven evaluation of spelling errors might be how well they represent the sounds of words according to the conventions of the orthography in question. Spelling errors of less advanced spellers and of disabled spellers are usually less consistent and more idiosyncratic than those of skilled spellers (Bosman, 1994; Bosman & de Groot, 1991; Bruck, 1988; Bruck & Waters, 1988; Lennox & Siegel, 1993; Waters, Bruck, & Seidenberg, 1985). But, there is no basis for the assumption that phonology plays a less important role in less advanced and disabled spellers (cf. Holligan & Johnston, 1991). In fact, it is highly likely that the phonologic properties of words overwhelm the less able speller (compare the exaggerated phonologic effects in dyslexic readers compared to normal

readers; cf. Van Orden & Goldinger, 1996; Van Orden, Pennington, & Stone, 1990). To summarize, we believe that spelling errors cannot be reliably classified into two categories, which renders an explanation in terms of two independent spelling routes superfluous. In the next section, we show how a single process framework, developed to explain word perception, also explains spelling performance. Word perception models usually do not incorporate spelling (Coltheart, Curtis, Atkins, & Haller, 1993; McClelland & Rumelhart, 1981; Seidenberg & McClelland, 1989), and spelling models do not include word perception (Brown & Loosemore, 1994; Houghton, Glasspool, & Shallice, 1994; Olson & Caramazza, 1994). The following proposal is an attempt to incorporate both in a common framework. A Dynamic Systems Framework for Spelling and Reading Our proposal derives from a new framework for word perception (Stone & Van Orden, 1994; Van Orden & Goldinger, 1994; Van Orden et al., 1990). This framework is rooted in dynamical systems theory, which supplies a new metaphor for cognitive systems (e.g., Thelen & Smith, 1994). Space requires a severely abridged version of this account; interested readers are referred to the original papers. Figure 10.1 depicts the macro dynamic of word perception described in Van Orden and Goldinger (1994).2 Three families of fully interdependent subsymbols3 (nodes) are assumed for a recurrent network model. Dynamics among nodes are sufficient to mimic performance attendant on word perception. In a model, the presentation of a printed word activates letter nodes that, in turn, activate phoneme and semantic nodes. Following initial activation, recurrent feedback dynamics begin among all these node families. The assumed dynamics are similar to those of the Interactive-Activation model of McClelland and Rumelhart (1981; see Stone & Van Orden, 1994). Behaviorally meaningful structure emerges in positive feedback loops among the three sets of nodes. The order in which feedback loops cohere is determined by the history of bidirectional correlations between words' printed forms and their linguistic functions (cf. Varela, Thompson, & Rosch, 1991). 2 We use macro and micro as relative terms. What is macro for word perception could be micro for discourse processing. Likewise what is micro for word perception could be macro for letter perception (cf. Ziegler & Jacobs, 1995). 3 The term subsymbol does not refer to a lower level symbol in the sense used in representational theory. Subsymbols are simply pragmatic notations for the purposes of modelling or illustration. They are not to be taken as psychologically real or as fundamental units of cognition (for an in-depth discussion of this issue, see Van Orden & Goldinger, 1994; Putnam, 1981).

Fig. 10.1. An illustration of the macro dynamic that describes reading and spelling performance in a recurrent network. The boldness of the arrows indicates the overall strength (self-consistency) of the relations between the respective node families. At the macro level of description, node families differ in overall strength and consistency of relations with other node families, as illustrated by the relative boldness of arrows in Fig. 10.1. Overall, the relations between letters and phonemes in alphabetic languages support the most powerful bidirectional correlations. The same letters and phonemes occur together in very many words. Phoneme-semantic relations and letter-semantic relations are less strongly correlated. Phonemes and semantic features, and letters and semantic features covary much less systematically. However, phoneme-semantic relations support stronger correlations than letter-semantic relations. This is true because, essentially, we speak before and more often than we read. Once in place, this asymmetry is self-perpetuating. Reading strengthens phoneme-semantic connections because phonology functions in every instance of printed word perception. Thus, even the exceptional condition of a person who reads more than she speaks supports phoneme-semantic connections that are at least as strong as letter-semantic connections. Also, in principle, if a coherent positive feedback loop forms between phoneme nodes and semantic nodes, before the feedback loop between letter nodes and semantic nodes, then printed or spoken discourse may proceed without settling the feedback loop between letter nodes and semantic nodes. The absence of coherence in the latter feedback loop may preclude strengthening the connections between letter nodes and semantic nodes (cf. Grossberg & Stone, 1986). The relative strength of the relations between letter and phoneme nodes illustrates why phonology supplies such powerful constraints on word perception. Stated differently, it explains why phonologic mediation is fundamental to reading (and spelling). Strong bidirectional connections between nodes yield powerful feedback loops that cohere very early in a model's dynamics. Abundant empirical evidence agrees with this claim (Berent &

Perfetti, 1995; Bosman & de Groot, 1995, 1996; Carello, Turvey, & Lukatela, 1992; Perfetti, Zhang, & Berent, 1992; Van Orden et al., 1990). In Fig. 10.2, we zoom in on the micro dynamics of fine-grain, letter-phoneme relations. In Fig. 10.2a, the presentation of the word hi has activated the letter nodes H1 and I2, which activate the phoneme nodes [h1] and [a12], as well as competing correlated nodes such as [i] (as in hit), which must be inhibited. Figure 10.2b shows how, in turn, phoneme nodes feed back activation to letter nodes (illustrated for the phoneme nodes [h1] and [a12]). [a12] activates the correct letter nodes H1 and I2 as well as competing letter nodes. For example, [a12] activates the letter node Y2 as in my or by. Dynamics from this point on select a ''correct'' combination through inhibition of competing nodes. Reliable performance emerges if the overall bidirectional configuration of connections between the letter nodes H1 and I2 and the phoneme nodes [h1] and [a12] favors coactivation of these four nodes. This advantage grows over time as the "strong grow stronger," and the "weak grow weaker" (cf. McClelland & Rumelhart, 1981). This is illustrated in Fig. 10.2c, which combines the flow of activation from letter nodes to phoneme nodes and from phoneme nodes back to letter nodes, as assumed in a recurrent network. The key to how one might apply this model to spelling is that all connections are bidirectional, which means that activation flows in both directions. Thus, activation arising in semantic or phoneme nodes may generate a coherent pattern of activity across letter nodes. This characteristic of recurrent models has important implications for word perception as well. It predicts that word perception should be affected by the relative consistency of phoneme-letter relations. In other words, not only does it matter for visual word perception that a word's spelling may have more than one pronunciation (e.g., Gibbs & Van Orden, 1995), it also matters that a word's pronunciation may have more than one spelling. Stone, Vanhoy, and Van Orden (1995) tested this hypothesis using a grain size of spelling-to-phonology that was larger than letters and phonemes, namely, onsets and rhymes (or bodies). The onset of one-syllable words is the initial consonant cluster (STR in Street), and the rhyme or body is the vowel and the final consonant(s) (EET in Street). Although letter phoneme correlations are tracked at the grain size of letters and phonemes, the overall pattern of weights will reflect correlational structure at any larger grain size. It turns out that, for English, correlations at the grain size of onsets and rhymes are highly predictive (Treiman, Mullennix, Bijeljac-Babic, & Richmond-Welty, 1995). Stone et al. (in press) used four sets of words in a 2 x 2 design. Bidirectionally consistent words were consistent in both spelling-to-phonology and phonology-to-spelling. An example is the word lust. Its spelling body _UST is only pronounced one way in the various words that share this spelling body, and its pronunciation body /_ust/ is only spelled one way in the words that

Fig. 10.2. A highly simplified illustration of micro dynamics that describe reading and spelling performance for the word Hi. The indices refer to the positions of the letters or phonemes in the word Hi. A recurrent network model presented with the written word Hi sends feed forward activation from letter nodes to phoneme nodes (Fig. 2a) and, in turn, feeds back activation from phoneme nodes to letter nodes (Fig. 2b). Figure 2c illustrates a resonance that emerges between letter and phoneme nodes corresponding to Hi.

share this pronunciation body. A second set of words were bidirectionally inconsistent. For example, the spelling body _EAK in bleak has multiple pronunciations, as in break and leak, and the pronunciation body /_eak/ has multiple spellings, as in freak and creek. The third and fourth sets of words were consistent in one direction but inconsistent in the other. The example heap has a spelling body _EAP that is always pronounced the same, but the pronunciation body /_eap/ can be spelled multiple ways, as in creep and leap. The contrasting example hull has a pronunciation body /_ull/ that can only be spelled one way, but a spelling body _ULL that can be pronounced multiple ways, as in dull and pull. In a lexical-decision task, words that were consistent in both directions yielded faster correct "yes" response times than words that were inconsistent in either direction. Recently, Patrice Gibbs (personal communication, May 1995) found similar effects in a naming task. Thus, the fact that a pattern of phonology can be spelled more than one way even affects performance in simple reading tasks. These empirical findings agree with our suggestion that spelling and reading are fundamentally related. Returning to Fig. 10.2c, reading the word hi not only activates the phonemes [h1] and [a12], and the letters H1 and I2 but also all multiple possible alternative spellings of the phoneme [a12]. Thus, reading a word correctly requires that incorrect phoneme nodes are inhibited, just as spelling a word correctly would require that incorrect letter nodes are inhibited. In the case of reading, however, the letters are presented to the model, so phoneme-letter inconsistency is less likely to yield an incorrect pattern of activation across letter nodes. The match between letters presented to the model and pattern of letter activation fed back from phoneme and semantic nodes actually accelerates the formation of correct feedback loops (as illustrated by the bold arrows in Fig. 10.2c). In spelling, however, a model must generate this pattern from phonology and semantic activation alone. There is no environmental support for correct letter nodes. Activation of letter nodes is determined by micro relations between phonemes and letters and macro relations among phonology, semantics, and spelling. In English orthography, there are generally more possible spellings for a particular word than possible readings; for example, the phoneme [i:] has the following possible spellings: Y as in entry, EY as in key, EE as in deep, EA as in leaf, and IE as in chief. Another example is the 36 possible spellings of the word she (see Simon & Simon, 1973).4 This is the micro basis for the asymmetry between spelling and reading (Barry, 1994; Stone et al., in press; Waters et al., 1985). Stone et al. (in press) estimated that 69% of low-frequency English one-syllable words are letter-to-phoneme consistent (at the 4 In the case of she, according to Simon and Simon (1973), /sh/ can be spelled in nine different ways (ti, sh, ci, ssi, si, c, ch, t, s), and /e/ in four different ways (e, ea, ee, ie).

grain size of onsets and rhymes) but that 72% of this sample are phoneme-to-letter inconsistent (at that same grain size). Another estimate indicated that 72% of all letter-to-phoneme, consistent, one-syllable words were phoneme-to-letter inconsistent, which suggests that phoneme-to-letter inconsistency is the rule for English. This characteristic is not restricted to English, however. Alphabetic orthographies such as Dutch, French, German, and Spanish are also more inconsistent in their phoneme-to-letter relations than in their letter-to-phoneme relations (the exceptions being unpointed Arabic and unpointed Hebrew; see Berent, Frost, & Perfetti, chap. 11, this volume). Both spelling and reading are powerfully constrained by the relatively strong correlational structure of the letter-phoneme dynamic. However, inconsistencies in these relations must be resolved by other sources of constraint. When a model "reads" a low-frequency, letter-to-phoneme inconsistent word such as pint, the more consistent relation between spelling and phonology rhymes with mint (Kawamoto & Zemblidge, 1992). Additionally, the letter-phoneme dynamic yields two correct pronunciations for words such as wind, although it would favor the more regular pronunciation (Kawamoto & Zemblidge). In both these cases, relatively strong semantic-phoneme relations may supply sufficient constraints for the appropriate phonology (Strain, Patterson, & Seidenberg, 1995). In the case of wind, semantic constraints may also be due to context. Contextual sources of semantic activation contribute via the relatively strong connections between semantic and phoneme nodes (cf. Azuma & Van Orden, in press; Stone & Van Orden, 1989). Now consider spelling, however. It must resolve the inverted patterns of ambiguity in the phoneme-letter dynamic. When a model "spells" a low-frequency, phoneme-to-letter inconsistent word, such as heap, the more consistent spelling for /_eep/ would be as in deep. Additionally, the phoneme-letter dynamic yields two correct spellings for homophones such as deer/dear. In these cases, correct spelling relies on relatively weak semantic-letter relations to supply sufficient activation of the appropriate letters (as illustrated in Fig. 10.1). Even contextual support is filtered through the weaker connections between semantic nodes and letter nodes. This relatively weak support for spelling (the semantic-letter relations) compared to the stronger one for reading (the semantic-phoneme relations) is the macro basis for the asymmetry between spelling and reading. To summarize: Spelling is more difficult than reading because phoneme-letter relations are more inconsistent than letterphoneme relations and because the phoneme-letter inconsistencies must be resolved by the relatively weak semantic-letter dynamic, whereas, in reading, letter-phoneme inconsistencies are resolved by the stronger semantic-phoneme dynamic. The fact that we engage less in spelling than in reading enhances this fundamental asymmetry between spelling and reading. Thus, to achieve a

spelling level that is comparable to reading would require building stronger correlations between words' meanings and their spellings (or a language with fewer inconsistent phoneme-to-letter relations). Finally, the existence of powerful bidirectional correlations between letter and phoneme nodes explains why both spelling and reading appear to be phonologically mediated. In particular, this explains the preponderance of phonetically accurate errors in spelling. The Relation Between Learning to Spell and Learning to Read The theoretical account presented previously assumes a close relationship between spelling and reading, but it also predicts an asymmetry between the two skills. Our earlier examples showed that hundreds of readings of the (proper) spelling of a word do not guarantee correct spelling. Beyond circumstantial evidence, experiments with beginning readers also show that reading is not always effective for learning to spell. For example, Dutch children with 7 months of formal spelling and reading instruction made equal numbers of spelling errors in new words they read 18 times and in new words they read only three times (Bosman & de Groot, 1991). In another study, Dutch children with 10 months of formal instruction made equal numbers of errors in new words they read six times and in words they read only twice (Bosman & de Groot, 1992). Only with 10 months of formal reading and spelling instruction and words presented at least nine times did spelling performance improve through reading (Bosman & de Groot, 1991). Moreover, spelling performance of adults who read pseudowords once, twice, three times, four times, or eight times, only benefited from the "eight times" condition (Gompel, Tromp, de Vries, & Bosman, 1990). In most of the aforementioned studies, spelling performance was measured by means of a dictation test. That is, the experimenter read the words, and the child was asked to write them down. In one study, however, spelling performance was assessed in both a dictation task and by means of a two-choice recognition test (Bosman & de Groot, 1992). In the two-choice recognition task, the child was presented with the word BLAUW (blue), and a phonologically plausible misspelling BLOUW, and was asked to pick the correct spelling. As in the previous studies, it did not matter whether the child had seen (i.e., read) the words twice or six times. The recognition scores were the same in both cases, but recognizing the correct spelling was easier than producing it even after the recognition scores were adjusted for guessing. This finding is interesting. It indicates that assessment of spelling skill is strongly task dependent. Children (and adults alike) appear as better spellers when their knowledge of words' spellings is tested

in a recognition task. More importantly, it is consistent with our explanation as to why spelling is more difficult than reading. Recognizing spelling is more similar to reading because the child can see the letters of the correct spelling. Alternatively, producing a spelling requires the child to generate the correct spelling from phonology and semantics. In other studies, we compared the effectiveness of reading practice for learning to spell with explicit methods of spelling practice: copying (writing down the word into a notebook), problem naming (practicing the ambiguous phoneme(s)), visual dictation (writing down the word after it has been presented for a brief period of time), word composition (making up the word using letter tiles), and oral spelling (spelling the word aloud). Children benefited most from oral spelling, and adults benefited most from oral spelling while learning to spell pseudowords. Most importantly, however, all spelling-instruction methods were superior to just reading as a means to learn the spelling (Bosman & de Groot, 1992, Bosman & van Leerdam, 1993; Gompel, Tromp, de Vries, & Bosman, 1990; van Daal, van der Leij, & Geertvliet-van der Hart, 1989; van Doorn-van Eijsden, 1984). Another interesting result from the previous studies is that spelling performance benefited most when the whole word was practiced. In principle, practicing the spelling of the whole word is redundant in a relatively shallow orthography such as Dutch because the major part of each word is unambiguous and can be derived by phoneme-to-letter rules. Thus, practicing the ambiguous part of the word, as in the problem-naming method, should be as effective as practicing the whole word (as in oral spelling). Nevertheless, the whole-word, oral-spelling condition yielded superior spelling performance for all participants at all ages. This finding is also interesting with respect to our account of spelling and reading. General knowledge about the relationships between letters and phonemes is not sufficient for correct spelling. The spelling context in which letters are embedded, which is unique for all words except homographs (e.g., wind), contributes strongly to knowledge about the spelling of words. In our account, we illustrated the intricate interplay between letters and phonemes by showing how each letter, each phoneme, and each semantic node contributed to the emergence of a word's spelling or a word's reading. Again, reading is not a very effective way to learn the spelling of a word. This raises the complementary question: Is learning to spell an effective way for learning to read? Again, most orthographies are more consistent in their letter-to-phoneme relation than in their phoneme-to-letter relation. It is possible that learning about the phoneme-to-letter relation strengthens the letter-tophoneme relation. However, studies that have investigated this issue yielded conflicting results, and results that are difficult to interpret. Uhry and Shepherd (1993) conducted a training study in which beginning readers from Grade 1 were instructed in phonemic segmentation and spelling. Their

findings indicated that the spelling training was beneficial for reading, but the training method left the participants ample time to practice reading as well because the words remained visible during the training. This confound masks the basis of better reading performance. The same problem occurs for results from studies by Ehri and Wilce (1987) and Roberts and Ehri (1983). Bosman, de Groot, and van Leerdam (1995) conducted spelling-training experiments in which reading and spelling were disentangled. Children and adults practiced the spellings of letter strings they had not seen before, and they were never visually confronted with the words. First graders were taught the spellings of actual words, whereas the adults learned the spellings of pseudowords. The spelling training was a form of the oral-spelling instruction method. After the experimenter named the word (or pseudoword), the participants spelled the word aloud and appropriate feedback was provided. Each word was practiced four times. The experiment included two control conditions. In one control condition, a set of words was repeated orally after the experimenter, and the second control condition included to-be-spelled words that were not practiced at all. Later, in a naming task, orally spelled and control repetition words were read faster than the words that were not practiced in the training, but there was no effect of oral spelling over simple repetition. A subsequent test showed that both groups learned the correct spelling of the oral-spelling items but not those of the items in the repetition condition. These results suggest that learning the spelling of words without visual presentation does not benefit reading performance over mere repetition. This issue is a subject of our ongoing research. We conclude this chapter with some general remarks concerning the implications for education. Some Implications for Spelling Instruction In this final section, the discussion emphasizes formal spelling instruction of normally developing children in the Netherlands, but the general implications hold for other languages too. As becomes clear, spelling difficulties should not be viewed as a static problem; they change over time. Over 80% of Dutch schools use a phonics-based reading-and-spelling method called "Veilig leren lezen" (Learning to read safely, Caesar, 1979). It is a fairly rigid preprogrammed curriculum with a strict day-to-day and week-to-week progression. Initially, the child is exposed to monosyllabic words that are predominantly consistent in their letterto-phoneme relations. Thus, proper phonemic analysis provides the beginning speller with predictable spelling patterns. After 4 months, children are presented with words containing inconsistent phoneme-to-letter relations. In first grade, this is mainly limited to the
< previous page

next page > Page 187
following phonemes: [ei] can be spelled IJ as in blij (happy), or EI as in geintje (joke); [ou] can be spelled AU as in paus (pope), or OU as in touw (rope); and [x] can be spelled G as in zeg (say), or CH as in lach (laugh). Dutch first graders primarily face the problem of spelling ambiguity of words with historically determined spelling patterns (cf. Assink, 1990). The spelling pattern of these words must be memorized because phoneme-to-letter analysis yields ambiguity in the letter pattern, and there are no rules to disambiguate these patterns. At the end of first grade, children are presented with spelling ambiguities that can be solved by applying rules. Spelling plural forms of nouns generally consists of adding the morpheme -EN at the end of the singular form. For example, the phoneme-toletter, consistent singular noun boek [book] becomes boeken, which is a phoneme-to-letter, consistent plural noun. However, a large proportion of phoneme-to-letter consistent singular nouns, for example, sok [sock], have a plural form that is phoneme-toletter inconsistent, namely, sokken (and not soken). Phonemic analysis of sokken is ambiguous with respect to the spelling of the phoneme [k]. An additional rule is needed to correctly spell the word, namely, if the body of a singular noun consists of a single-letter vowel and a consonant, then double the final consonant before adding the EN-morpheme (compare the English spelling rule of doubling the final letter B of rub in rubbing, but not the final K in looking). Other types of spelling problems arise with increasing reading and spelling experience. The majority of phoneme-to-letter inconsistent words can be spelled correctly by the application of a set of linguistic rules. But even the most skilled adult spellers are usually unaware that these rules exist or are unable to apply them because of their rather complex nature (Assink, 1985, 1990; Verhoeven, 1979). In most cases, therefore, children and adults alike memorize the spellings of words with ambiguous spelling patterns. The problems for Dutch spellers in first grade begin a neverending progression. Spellers encounter increasingly complex relations between phonemes and letters (Verhoeven, 1979; see Bailet, 1990, for the English language). The types of problems that appear in lower grades disappear in higher grades but are replaced with new types of problems. In turn, these problems disappear, to be replaced yet again by new spelling problems on entering high school. Changing spelling problems poses a challenge for the provision of detailed directions, but some implications, all related to the assumption of phonologically mediated spelling, are less specific to a particular type of spelling problem. For most people spelling acquisition lasts until adulthood, and for some people, learning words' spellings is a life-long enterprise. Dutch spellers, and probably most non-English speakers face an additional problem. New words, in particular from English, are continuously being added to their languages, and these loan words are, by nature, sound-to-spelling inconsistent. The

spelling of loan words with highly inconsistent phoneme-to-letter patterns may best be learned by phonologically regularizing the pronunciation of a word (Bråten, 1994; Ormrod & Jenkins, 1989). In fact, corned beef, rawhide, and palmolive are regularized in standard Dutch and do not retain the English pronunciation (/kor/ /net/ /bief/, /ra/ /we/ /de/, and /pol/ /mo/ /lee/ /ve/, respectively). Pronouncing an inconsistent word as a letter-to-phoneme regular word may also serve as a mnemonic for deriving its correct spelling. Examples are "private pronunciations" of the word aisle as /ai/, /s/, /le/, or the word Wednesday as /wed/, /nes/, /day/. This method stems directly from the assumption that spelling and reading are phonologically mediated. Another issue related to the assumption of phonologically mediated spelling is the role of dialects in education. Dutch spelling is based on Standard Dutch (Algemeen Beschaafd Nederlands, ABN). Children who do not also speak Standard Dutch cannot take full advantage of the consistency between phonemes and letters. Various examples from spelling tests show the influence of children's dialect on their spelling performance (Bosman & van Leerdam, 1993). However, there are also situations in which children who speak a dialect can use the knowledge of their local dialect to spell otherwise, ambiguous spelling patterns. Children in De Achterhoek and De Veluwe (middle-eastern part of The Netherlands) generally know the spelling of the phoneme [ei] because their pronunciation of words spelled with IJ as in mijn (/mien/ meaning `mine') is different from the EI as in klein, /klein/ meaning `small'), whereas in the rest of the country, the two spelling patterns IJ and EI have identical pronunciations (/mein/and /klein/). A final issue concerns the use of spelling tests that present incorrect spellings to students in the form of multiple-choice tests. In a multiple-choice test, the correct spelling of a word is presented together with one or more incorrect (pseudohomophone) spelling(s), and students are required to mark the correct spelling, for example, harrass, harass or harras; a Dutch example is: enigzins, enigszins (somewhat), or enigsins. An important educational question is whether spelling performance is affected by encountering phonologically acceptable misspellings. We both experienced the erosion of spelling knowledge after conducting large numbers of experiments using pseudohomophones. These private experiences are corroborated by experimental studies (see Brown, 1988, for an overview; see Ehri, Gibbs, & Underwood, 1988, for a null effect). It appears that being visually exposed to incorrect, but phonologically possible spellings may have an adverse effect on extant spelling knowledge. Thus, despite the convenience of multiple-choice tests, they may not be the best possible way of testing spelling performance (Bradley & King, 1992). We conclude that spelling and reading are interdependent, and phonology mediates both of them. Reading, however, is not the most effective way to learn to spell. Correct spelling seems to require strategies specific to this

skill strategies that strengthen or supplement semantic-letter, correlational structure. Apparently, the most effective methods of instruction mimic actual spelling production. However, which method of instruction is most effective may change over time as children encounter an increasing variety of complex relations between phonology and spelling. Successful instruction must take all this and more into account, keeping in mind the unique matrix of proclivity, background, and motivation that each child brings to this task.

Chapter 11 The Inhibition of Polygraphic Consonants in Spelling Hebrew: Evidence for Recurrent Assembly of Spelling and Phonology in Visual Word Recognition Iris Berent Florida Atlantic University Ram Frost Hebrew University Skilled spelling entails two subcomponents. One permits the spelling of new words and nonwords. A second subcomponent entails the retrieval of idiosyncratic word-specific orthographic knowledge. Spelling models (e.g., Barry, 1994; Jorm, 1983; Kreiner, 1992; Link & Caramazza, 1994) account for these two abilities by postulating two strategies for assigning an orthographic representation to a word. One is a productive strategy that assembles a spelling representation by mapping the word's phonemic constituents onto graphemes. Such a strategy is necessary to account for the spelling of nonwords such as /blin/. Because /blin/ does not correspond to any English word, its spelling cannot be obtained by consulting the spelling of any particular English word. Instead, it must be generated "from scratch." Spellers can do so by mapping each of the phonemes of /blin/ onto a letter. There is evidence that the assembly strategy contributes also to the spelling of familiar words. Supporting the contribution of the assembly process in spelling are the findings that most spelling errors among good (Barron, 1980; Frith, 1980) as well as poor (Bosman, 1994; Frith 1980) spellers are phonologically plausible, that a child's early spellings are affected by the phonetic and phonological properties of the word (Read, 1971; Treiman, 1994), and

that the performance of skilled spellers in on-line spelling tasks is impaired by polygraphy (Kreiner, 1992). However, the assembly of phonemes into letters is insufficient to account for skilled spelling in many orthographies in which spelling cannot be fully predicted from the word's phonological structure. For instance, the assembly of a spelling to the word rain may yield also the representation rane. To correctly spell the word rain, readers must rely on a second strategy. This strategy consults an orthographic representation that is specific to this word. It accesses the orthographic lexicon and addresses a stipulated orthographic representation of particular words. The contribution of word-specific knowledge in spelling is supported by the finding that the advantage of good versus poor spellers is particularly noticeable for words whose spelling requires wordspecific knowledge (i.e., exception words; Barron, 1980). Although it is clear that both strategies are necessary for skilled spelling, there are questions regarding their relative contribution. In particular, these questions concern the role of the assembly mechanism in the spelling of familiar words. Because spellers possess a stipulated knowledge of the word as a whole, the application of the assembly procedure seems unnecessary for such words. The usefulness of this productive mechanism is further reduced in orthographies that exhibit unpredictable mapping functions between phonemes and graphemes. Consider again the word rain. The spelling of the vowel phoneme in this word is unpredictable because English supports several ways to spell the vowel that are all quite common. Conversely, English spelling may be unpredictable due to the use of rare, irregular correspondences between graphemes and phonemes (e.g., gauge). Orthographies that manifest opaque correspondences between graphemes and phonemes are termed deep orthographies (for a discussion, see Katz & Frost, 1992). In such orthographies, the application of the assembly mechanism is not only unnecessary but also detrimental because it may result in an erroneous representation. The primary issue discussed in this chapter concerns the role of the assembly mechanism in a deep orthography among skilled spellers. Specifically, we are concerned with the following questions: (a) Do skilled spellers assemble a graphemic representation in spelling familiar words? (b) If an assembled mechanism is activated in spelling, then how can spellers prevent spelling errors? The questions regarding the role of assembled information in spelling echoes a parallel debate in the reading literature: Do skilled readers recognize familiar words by a process of grapheme-phoneme assembly? (for a review, see Berent & Perfetti, 1995; Frost, 1995; Seidenberg & McClelland, 1989; Van Orden, Pennington, & Stone, 1990). On first examination, it seems that the roles of assembly in the perception (reading) and production (spelling) of written language are quite independent. The assembly function in
< previous page

next page >

page_197
next page > Page 197
spelling maps phonemes to graphemes, whereas, in reading, it converts graphemes to phonemes. The activation of this mapping function in one direction (e.g., spelling to phonology) does not necessarily implicate its activation in the opposite direction (e.g. phonology to spelling). Furthermore, the predictability of these mappings may differ in each direction. Some orthographies (e.g., French) exhibit predictable grapheme-phoneme correspondences but unpredictable phoneme-grapheme mappings. In other orthographies (e.g., Arabic, Hebrew), a word's spelling is more predictable than its pronunciation from print.1 What is the relationship between the assembly of spelling and phonology? On one account, the two directions of the assembly process are independent. Thus, the activation of phonemes from graphemes, for instance, should be unaffected by the predictability of the correspondence between phonemes and graphemes. To illustrate the predictions of this account, consider again the word rain. The assembled phonology of this word is perfectly predictable from its spelling. In contrast, the spelling of rain cannot be predicted from its sound. In reading the word rain, readers may attempt to assemble its phonology. If the functions of phonology and spelling assembly are independent, then the assembly of phonology in reading rain should not be affected by the unpredictability of its spelling. However, an alternative account may predict a close relationship between the two functions of assembly. In this account, assembly is a recurrent process in which graphemes and phonemes are mapped bidirectionally. Mapping inconsistency in one direction thus constrains the assembly process as a whole (see also Stone & Vanhoy, 1994; Stone, Vanhoy, & Van Orden, in press). Hence, in spite of the fact that the phonology of rain is completely predictable from its letters, the assembly of its phonology may, nevertheless, be affected by the unpredictability of its spelling. As we illustrate in the following sections, Hebrew orthography presents the speller with considerable ambiguity in predicting a word's spelling from its phonology. This orthography provides fertile grounds for the examination of the dependency between the two directions of the assembly process. A second goal of this work is to extend the investigation of the relationship between the assembly of sound and spelling (Stone & Vanhoy; Stone et al., in press) to Hebrew orthography. In this work, we examine the dependency between the assembly of spelling and phonology: Does the assembly of a 1 We use the term predictability (Berent & Perfetti, 1995) to refer to the degree of certainty in which the output of the assembly function (e.g., phonemes) can be derived from its input (e.g., graphemes). The unpredictability in mapping could result either from inconsistency due to the existence of one to many mappings (e.g., the mapping of graphemes to phonemes in English) or from underspecification of the input (e.g., the absence of vowels in Hebrew; see Frost, 1995).

graphemic representation in spelling a word constrain the assembly of phonology from print? Our investigation of these questions is based on unpointed Hebrew, a script that manifests quite opaque correspondences between graphemes and phonemes in both directions. We examine whether the process of recognizing isolated Hebrew words is constrained by the predictability in which Hebrew phonemes are mapped onto graphemes. Specifically, we identify a spelling mechanism that is designed to protect word spelling from inconsistencies in mapping phonemes and graphemes. Such a mechanism, we believe, is required only if Hebrew readers assemble (rather than address) the spelling of familiar words. We then demonstrate that this spelling mechanism is activated in a reading task. Because this task clearly does not require the assembly of the word's spelling, our findings suggest that the assembly of a word's spelling is quite automatic. Moreover, evidence for automatic activation of graphemic assembled information in Hebrew, a deep orthography in which the mapping between phonemes to graphemes is highly unpredictable, indicates that the contribution of spelling assembly is quite general. We first assess the reliability of an assembly mechanism in obtaining the spelling of Hebrew words by describing some of the properties of the Hebrew writing system. We then propose a mechanism that permits spellers and readers to benefit from the assembly of both the word's spelling and its phonology in reading Hebrew, in spite of the fact that the information provided in the orthography is partial and unreliable. Finally, we provide empirical evidence for an automatic activation of assembled spelling and phonology in a reading task. We conclude with reviewing some of the implications of our proposal. The Reliability of the Assembly Mechanism in Reading and Spelling Hebrew: The Effects of Hebrew's Orthographic Structure Of the properties of Hebrew orthography, we note two features that are particularly important to spelling: its consonantal nature and its consonantal polygraphy. The consonantal nature of Hebrew orthography is one of the most widely known characteristics of this writing system. In Hebrew, letters represent mostly consonants, whereas vowels can be optionally superimposed on the consonants as diacritical marks. The diacritical marks, however, are omitted from most reading materials and are found only in poetry, children's literature, and religious texts. Thus, in its unpointed form, Hebrew orthography does not convey to the reader the full phonemic structure of

the printed word, and the reader is often faced with phonological ambiguity. In contrast to unpointed orthography, pointed orthography is a very shallow writing system. Vowel marks convey missing phonemic information, making the printed word phonemically unequivocal. The consonantal nature of unpointed script is a property that has obvious implications for reading. In the absence of vowels, readers of unpointed script are provided with quite impoverished information regarding the phonology of the word. Consequently, it has been argued that in reading unpointed Hebrew, readers access the word's meaning directly based on its graphemic representation. On this view, the assembly of the word's phonology from its print provides a relatively weak source of constraint on reading Hebrew words (Bentin, Bargai, & Katz, 1984; Bentin & Frost, 1987). The problems posed by the consonantal nature of Hebrew orthography are even more severe when the assembly of the word's spelling is concerned. Some vowels (mainly /o/, /u/, /i/) may be represented in print not only by points but also by letters. Thus, in assembling the spelling of Hebrew words, spellers must determine which vowels should be represented as letters and which ones should be omitted (Shimron, 1993). This decision, however, is completely unpredictable from the phonology of modern Hebrew.2 Because the representation of vowels in a word's spelling is highly unpredictable, spellers may limit the assembly of a word's spelling to consonantal information. On this account, the primary task of the speller in assembling a graphemic representation to Hebrew words is the assembly of the word's consonants. This process, however, is highly unpredictable due to another characteristic of Hebrew orthography its consonantal polygraphy. Modern Hebrew contains 18 consonant phonemes. Twelve of these consonants (/b/-/g/-/d/-/h/-/z/-/y/-/l/-/m/-/n/-/p/-/ts/-/r/-/sh/) are mapped into their letters unequivocally. In contrast, the representation of six consonants (/a//v/-/s/-/x/-/k/-/t/) is quite unpredictable as they can be represented by two distinct letters (see Fig. 11.1). Thus, the representation of these consonant phonemes in Hebrew is polygraphic.3 This polygraphy stems from a histori2 The distinction between the two forms of vowel spellings, by a marker or by a vowel letter, reflects an ancient distinction between different forms of vowels that contrast mainly in their length, long vowels being represented by the letters. This distinction, however, has been lost in modern Hebrew. Thus, modern spellers cannot predict whether a vowel letter is required based on the phonology of the word. Another possible source of information for determining the orthographic representation of vowels is an explicit knowledge of the word's morphology. However, such reflective knowledge may be inaccessible to the process of assembly. 3 Polygraphy is a property that is not unique to Hebrew. For instance, English manifests considerable ambiguity in the spelling of vowels. In contrast to Hebrew, the ambiguous graphemes tend to be represented by letter combinations rather than single letters. Consonantal polygraphy in English seems more limited in its scope compared with Hebrew. Similar to vowel ambiguity, the competing consonant alternatives differ in their complexity. For instance, the phoneme /k/ may be spelled as either k, c. However, the phonological value of c depends on (footnote continued on next page)

In fact, some of these phonological distinctions can be found in some Jewish communities originating from Arab-speaking countries (footnote continued from previous page) the following vowel letter. Thus, its mapping is more complex than that of k. The spelling of these consonants may further be disambiguated by their position in the word and their frequency. The distributions of the two correspondences of /k/ are roughly complementary: The letter k appears in an environment in which c is mapped into /s/ (Venezky, 1970). In addition, the mapping of /k/ to k is less common than /k/ to c. Further research is required to determine the effect of consonantal polygraphy in such orthographies.

(e.g., Yemen) probably due to the fact that the same phonemic contrasts are distinctive in Arabic. However, most of these distinctions were lost among the communities originating from central and eastern Europe and they are no longer present among the majority of Hebrew speakers born in Israel (Morag, 1962). The presence of consonantal polygraphy poses severe problems in the assembly of a word's spelling. The fact that the number of graphemes in Hebrew is greater than their corresponding phonemes implies that there is a greater indeterminacy in mapping Hebrew consonant phonemes into graphemes than in converting graphemes to phonemes. The polygraphy of the consonantal system in Hebrew is, thus, more problematic in the assembly of a word's spelling from its sound than vice versa. Although spelling ambiguity can be reduced in some cases by orthographic constraints and by phonological or morphological knowledge, by no means can such information eliminate the problem of polygraphic ambiguity as a whole. The severity of the ambiguity in the spelling of consonants is particularly important because consonants in unpointed script specify almost uniquely the assembled spelling of the word as a whole. Because each consonant in a consonantal script carries a greater amount of information (compared to a full writing system), an incorrect spelling of the word's consonants is deleterious for the reader's ability to recognize the word's meaning. Furthermore, the misspelling of consonants may lead to the activation of competing irrelevant semantic information due to the prevalent homophony in the Hebrew writing system. In summary, we have identified two problems in Hebrew orthography: the omission of vowels and the consonantal polygraphy. The absence of vowels is considered detrimental to the assembly of phonemes from graphemes but has little influence on the assembly of the word's graphemic representation from its phonemes. In contrast, the consonantal polygraphy of Hebrew is relatively harmless in assembling the word's phonology from the orthography, but it poses serious problems in assembling the word's spelling. Given the severe ambiguity in predicting a word's spelling by assembly, what is the role of assembly in generating the spelling of Hebrew words? If assembly does contribute to the spelling process, how can Hebrew spellers avoid constant misspellings of consonants? A Unified Model of the Assembly of Spelling and Phonology in Processing Hebrew Words In this section, we outline a model that provides a unified account of the role of assembled information in spelling and reading Hebrew words. We have noted that the information specified in the assembly of both spelling
< previous page

and phonology may be partial and limited to exclusively consonantal information. In reading, this is due to the absence of most vowels from the orthography, whereas in spelling, spellers might be unable to decide which vowels should be represented by a vowel letter. Thus, the assembly of both spelling and phonology can result in only partial information. Yet, such information may be nevertheless sufficient to activate the process of assembly. The central premise of our proposal is that the assembly of the word's spelling from speech, or its phonology from print, can be triggered by impoverished input that specifies exclusively consonantal information. Underspecified phonological information thus contributes to the recognition of Hebrew words (see also Shimron, 1993). The ability of spellers and readers to use such impoverished information may reflect the fact that the distinction between consonants and vowels respects an essential linguistic distinction in the grammar of Hebrew. One of the most important properties of Hebrew morphology is the segregation of consonant and vowel morphemes. In Hebrew, as in other Semitic languages, all verbs and the vast majority of nouns and adjectives are formed by inserting a root morpheme, a string of consonants containing (in most cases) three phonemes, into a preexisting word pattern that specifies vowels and, sometimes, also additional consonants. For instance, the words /zemer/ (a song), /zimra/ (singing), and /tizmoret/ (orchestra) are formed by inserting the root Z-M-R into one of three preexisting morphological patterns (we denote the root consonants as C): CeCeC, CiCCa, tiCCoCet. Thus, morphologically related words always share the same consonantal root. The consonantal root also plays an important role in accessing the mental lexicon. It interconnects the lexical entries of morphologically related words (Frost & Bentin, 1992). The root serves as an interface that mediates the access to all morphologically related words. Supporting this view is a recent study by Frost, Forster, and Deutsch (in press) demonstrating that the priming of a target by its root consonants facilitates lexical decision to targets that are derivations of the root. These results suggest that access to a word's meaning is achieved by the initial activation of consonantal information corresponding to the root. If access to the lexicon requires the activation of an interface that is purely consonantal, then the absence of vowel information in the representation assembled by spellers and readers may not deprive them from any information that is necessary for lexical access. The assembly of the word's phonology from print may provide the readers with the root consonant phonemes and, thus, with the key to accessing the lexicon via the consonantal interface. As we have noted before, the assembly of consonant phonology is quite predictable. Hence, in spite of the absence of vowels in the script, the assembly of consonant phonemes provides an efficient means for accessing words' meanings in the mental lexicon.

The assembly of word spelling is more complex, however. Note that in assembling a word's spelling from speech, readers are faced with uncertainty not only regarding the representation of vowels but also regarding the representation of polygraphic consonants. A failure to choose the right alternative will not only result in a misspelling but, in fact, may also distort the word's meaning because it may yield a homophone word whose meaning is quite different. If the assembly of word's spelling indeed contributes to word recognition, then how should readers prevent spelling errors? Our model accounts for the prevention of misspellings by postulating a graphemic inhibitory mechanism in Hebrew spelling. This mechanism protects against spelling errors by suppressing the competing spellings of polygraphic consonants. There are several possibilities as to the exact implementation of this inhibition. Earlier in the discussion, we described two types of strategies governing skilled spelling: The assembly mechanism is a general, productive strategy that operates at a sublexical level. In contrast, the addressed mechanism employs word-specific information at the lexical level. The inhibitory mechanism could potentially be implemented at each of these levels within the spelling system: the lexical or the sublexical level. Consider first the lexical account. As readers become familiar with a word, they may develop a top-down inhibitory connection between the polygraphic consonant in the lexical representation and its competitor grapheme at the prelexical level (see Fig. 11.2). For instance, in the word /kelev/ (spelled klv, meaning ''a dog'') the consonant /k/ is polygraphic because it can be either mapped to the letter kaf or kuf (in the following discussion, we notate these two letters as k and q, respectively).4 According to the lexical account, the familiarity with /kelev/'s correct spelling results in the formation of an inhibition between the lexical representation of /kelev/ and the competitor grapheme, q. The greater the familiarity with /kelev/, the greater the inhibition becomes and, consequently, the more secure the spelling is. Thus, only real words that are familiar to the speller can inhibit their graphemic competitors. Nonwords lack a lexical representation, and they cannot inhibit competitor graphemes. There are two problems with this version of the inhibitory mechanism, however. One is that the encoding of the competition at a lexical level does not capture the fact that such a competition reflects an important generalization inherent in the writing system. Indeed, the competition between the graphemes k and q is not specific to the word /kelev/ but is a general problem faced by Hebrew spellers in the spelling of all orthographic stimuli, 4 For the sake of simplicity, we disregard the polygraphy of the final consonant /v/. The consequences of this polygraphy, however, are identical to those discussed for the initial consonant, /k/.

Fig. 11.2. A lexical model of polygraphic inhibition. The presentation of the spoken word /kelev/ results in addressing the representation of /kelev/ in the phonological lexicon, which, in turn leads to two simultaneous patterns of activation. One is the addressing of the orthographic representation of /kelev/ in the orthographic lexicon. The other is mapping the consonants of /kelev/ onto graphemes by a sublexical assembly mechanism. Because the consonant /k/ is polygraphic, its assembly yields the activation of two graphemes, k and q. However, according to the lexical model, the erroneous grapheme q is immediately suppressed by a top-down activation from the orthographic lexicon (inhibitory connections are notated as crossed-bold arrows). This inhibition leaves the speller only with the correct representation of klv. The spelling computed by the speller (in the rectangular box) reflects the contribution of these two sources of information.

regardless of their lexical status. A lexical mechanism may protect the spellers from misspellings of familiar words, but it will not be able to encode the presence of competition, let alone protect against it, for unfamiliar and new words. Obviously, however, these are precisely the unfamiliar words that are most vulnerable to misspellings. A more efficient way of preventing misspellings of both new and familiar words is to implement the inhibitory mechanism at the sublexical level. The competing graphemes may be each connected to a single consonant phoneme. The activation of a correspondence between the polygraphic consonant phoneme and one of its graphemes results in the inhibition of the connection between that phoneme and its competitor grapheme (see Fig. 11.3). Thus, in spelling /kelev/, the assembly of the phoneme /k/ results in two simultaneous patterns of activation. One is the activation of the grapheme k and, consequently, the activation of an inhibitory connection from /k/ to q. The other is the activation of the grapheme q, resulting in an inhibition from /k/ to the grapheme k. Consequently, the representation assembled to the word /kelev/ lacks an explicit specification of the grapheme corresponding to the phoneme /k/. The remaining graphemes, however, serve to address the orthographic lexicon, in which the identity of the missing grapheme could be recovered based on word-specific knowledge of /kelev/. Thus, in spite of its partial nature, the assembly of a word's spelling can be used by skilled Hebrew readers in retrieving the word's addressed spelling from the lexicon without resulting in spelling errors. Note, however, that the inhibition of competitor graphemes is predicted, regardless of the lexical status and familiarity of the orthographic string: Both familiar words and nonwords can inhibit their competitors. Hence, the implementation of the inhibition at the sublexical level is a general mechanism designed to protect spellers from misspelling due to the activation of assembled spelling. Our model further assumes that the assembly of a word's spelling and phonology are automatically activated in reading and writing Hebrew words. Indeed, it is precisely the automaticity in the assembly of a word's spelling that requires the protection of the inhibitory mechanism. Importantly, however, if the assembly of both phonology and spelling is automatic, then the presence of its input may be sufficient to trigger its activation. Thus, the activation between graphemes and phonemes is a two-way street (Stone & Vanhoy, 1994): The assembly functions of spelling and phonology are expected to recurrently feed each other until the representation is stabilized above some given threshold. This property of recurrence leads to an important prediction: Inconsistencies in the process of mapping phonemes to graphemes may affect the conversion of graphemes to phonemes as well. The prediction of recurrence may be illustrated using an English example. Consider again the word rain. As noted earlier, the assembly of this word's phonology from its letters is highly predictable. In reading the word rain,

Fig. 11.3. A sublexical model of polygraphic inhibition. As in the lexical account, the presentation of the spoken word /kelev/ results in addressing the representation of /kelev/ in the phonological lexicon, which, in turn leads to two simultaneous patterns of activation. One is the addressing of the orthographic representation of /kelev/ in the orthographic lexicon. The other is mapping the consonants of /kelev/ onto graphemes by a sublexical assembly mechanism. Because the consonant /k/ is polygraphic, its assembly yields the activation of two graphemes, k and q. In contrast to the lexical account, however, note that the activation of each grapheme results in the inhibition of its competitor (inhibitory connections are marked by a bold-cross arrow). This inhibition occurs entirely at the sublexical level of assembly. Because k and q inhibit each other, the resulting output of the assembly mechanism actually lacks a specification for the initial grapheme. However, this output nevertheless permits addressing the orthographic lexicon and retrieving the missing information. Thus, as in the lexical account, the spelling computed by the speller (in the rectangular box) reflects the contribution of both assembled and addressed information.

readers can thus easily map its letters onto phonemes. Once the phonemes of rain are assembled, their presence should automatically trigger the spelling assembly mechanism. Because the spelling of rain is unpredictable, its spelling assembly is expected to be impaired. As a result, the spelling inconsistency of rain should impair its reading, despite the fact that spelling assembly is clearly unnecessary in a reading task. This prediction was borne in the results of Stone and colleagues (Stone & Vanhoy, 1994; Stone et al., in press). Their findings demonstrate that lexical decision performance in English is affected by the consistency of mapping between graphemes and phonemes in each direction. Specifically, lexical decision to words such as rain, whose phonology is completely predictable, was impaired by the unpredictability of their spelling. Similar effects of spelling unpredictability are expected in reading Hebrew as well. Specifically, the presence of polygraphic consonants in print should inhibit the process of phonology assembly in reading. For instance, when presented with the word klv, readers will assemble the initial grapheme k into the phoneme /k/. Although this mapping function is completely consistent, the activation of the phoneme /k/ is expected to result in a recurrent activation to the competing letter q, which, in turn, will reduce the activation of both the correct letter, k, and the phoneme /k/. Consequently, the graphemic ambiguity of the polygraphic phoneme will impair its reading. In summary, we propose a model of Hebrew spelling and reading that makes the following claims: (a) Spelling and reading in Hebrew are obtained by the contribution of both assembled and stipulated information; (b) Consonantal information is sufficient to activate the processes of assembly: The assembly of consonant phonemes in reading proceeds in the absence of vowels; word spelling is constrained by the assembly of primarily consonant graphemes, in spite of their polygraphic ambiguity; (c) The contribution of erroneous graphemic information is prevented by mutual inhibitory connections between a phoneme and its competing graphemes implemented at the sublexical level; and (d) The activation between graphemes and phonemes is bidirectional. Thus, inconsistencies in the mapping of phonemes to graphemes affects the assembly of graphemes to phonemes as well. Inhibitory Activation of Spelling Competitors: Evidence from Reading In this section, we review some empirical evidence supporting the predictions of the model outlined earlier. First, if spelling Hebrew entails a process of graphemic assembly that resolves polygraphic ambiguity by the activation of an inhibitory mechanism, then we should expect evidence for inhibition among competitor graphemes. Second, if the inhibition operates at a sub-

word level, then it should be obtained regardless of the lexicality of the orthographic stimulus: Both words and nonwords should exhibit inhibition. Third, if the mapping between graphemes and phonemes is bidirectional, then evidence for inhibition should be obtained in each direction of the assembly process: The inhibition between competitor graphemes should emerge not only in generating the word's spelling from sound but also in assembling its phonology from print for the purpose of reading. Indeed, the evidence supporting our model is obtained in a reading task using the backward-masking technique. In a typical trial, the subject is presented with a target word, klv (pronounced /kelev/), that is briefly presented in upper case for 15 ms followed by one of several nonword masks presented in lower case: A pseudohomophone qlv, a graphemic mask, mlv, and a control mask, rsx (see Fig. 11.4). The mask is presented for 30ms and is followed by a pattern mask. Targets and masks are both unpointed. The

critical comparison in this experiment concerns the effect of two nonword masks: The pseudohomophone, qlv, and the graphemic mask, mlv. Both nonwords share the same number of graphemes in common with the word /kelev/. However, the pseudohomophone qlv is more similar to the target on the phonological dimension. In addition, the pseudohomophone contains the competitor grapheme q, whereas the graphemic mask, mlv, does not. How should the presentation of these two masks affect subjects' ability to recognize the target klv? Obviously, the introduction of any new visual input following a brief presentation of the target will interrupt its processing and inhibit its recognition. The recognition of the target under such difficult masking conditions will only be probabilistic. However, if the dimension distinguishing the two types of nonwords contributes to the processing of the target, then they will differentially affect target recognition accuracy. In our example, the pseudohomophone differs from the graphemic mask on two interrelated properties: One is its greater phonological similarity to the target, and the other is the presence of a polygraphic consonant. These two properties have distinct effects on each of the two processes of assembly, the assembly of spelling and phonology. The phonological similarity may facilitate the assembly of a phonological representation from graphemes. Indeed, similar backward-masking studies conducted in English observed a facilitation in target recognition accuracy when followed by a pseudohomophone compared to the graphemic mask (Perfetti & Bell, 1991; Perfetti, Bell, & Delaney, 1988). In contrast to these English studies, however, the phonological similarity between the Hebrew pseudohomophones and their targets is due to the introduction of a graphemic competitor. If Hebrew readers are equipped with an inhibitory spelling mechanism, then the presence of such a competitor grapheme may inhibit the assembly of spelling from the word's phonology. The examination of the combined effect of these two factors, phonological facilitation and graphemic inhibition, requires a more precise account of the interaction between the two processes of assembly and their locus. We have presented two accounts as to the locus of the inhibition. Consider first the predictions of the lexical account that attributes the inhibition to a top-down activation from the lexicon. This account assumes that only real word stimuli can inhibit their competitor graphemes. Thus, a polygraphic consonant in the target can inhibit its competitor in the mask, but the mask's polygraph cannot inhibit the target because the mask is a non-word. In fact, target recognition under the pseudohomophone condition should be at least as good as target recognition under the graphemic mask condition in the assembly of either spelling or phonology. In assembling the target's spelling, the pseudohomophone should be at least as beneficial as the graphemic mask because these masks are equated in their graphemic similarity to the target. At the level of phonology assembly, the pseudohom-

ophone may even facilitate target recognition compared to the graphemic control due to its greater phonological similarity to the target. Thus, the lexical account predicts that performance with the pseudohomophone mask should be at least comparable to the graphemic control. If readers assemble a phonological representation in reading, then the pseudohomophone should facilitate performance compared to the graphemic mask. Note however, that the pseudohomophone should never inhibit target recognition compared to the graphemic mask.5 In contrast to the lexical account, our model predicts that the pseudohomophone should impair target recognition compared to the graphemic mask. Because the inhibition originates at the sublexical level, its presence should be independent of the lexicality of the orthographic input. Specifically, when presented with the pseudohomophone qlv, readers may attempt to recognize it by converting letters to phonemes. This should result in assembling the consonant phonemes /klv/. Similarly, the graphemic mask mlv will result in the assembly of the consonant phonemes /mlv/. The critical difference between these masks occurs at the stage in which recurrence emerges in the system and the phonemes are mapped back onto graphemes. Consider first the effect of the graphemic mask. After a recurrent activation in which graphemes are mapped onto phonemes and back onto graphemes, the reader is left with mlv. Although the resulting representation differs from the desired one (klv), it does, nevertheless, provide some evidence for the right target. Importantly, the irrelevant information provided by the graphemic mask should not prevent the activation of the target. The state of affairs due to the presentation of the pseudohomophone qlv is quite different. The mapping of the phoneme /k/ onto a grapheme will result in an inhibition of the correct letter kaf, and consequently, an inhibition in target recognition. Hence, the sublexical account predicts that the pseudohomophone should inhibit target processing compared to graphemic control, and this inhibition should be independent of word frequency. The primary goal of the following experiments is to seek initial evidence for the presence of an inhibitory spelling mechanism in Hebrew. A second goal of the experiments described here is to investigate the constraints affecting the emergence of the inhibition phenomena. If inhibition in reading 5 According to the lexical account, the target cannot be inhibited by the pseudohomophone. However, this account does predict an inhibition to the pseudohomophone by the target. This inhibition should be observed as a decrease in the facilitory effect of the pseudohomophone. This decrease should be particularly noticeable for high-frequency words. Because high-frequency words are more likely to inhibit their competitor graphemes, the pseudohomophones of such targets are also more likely to be lacking a specification of the competitor grapheme, which is critical to assure their greater similarity to the target at the stage of phonology assembly. Thus, the lexical account may predict that the advantage of the pseudohomophone compared to the graphemic mask will be reduced for high-frequency words.

indicates the assembly of phonology, then it should obviously arise only under conditions that permit the assembly of phonemes from graphemes. We have pointed out that the consonantal nature of the Hebrew writing system permits the activation of only a partial phonological code. It is possible that, in the absence of sufficient vowel information, the assembly process will be blocked, resulting in the elimination of evidence for inhibition. However, our model assumes that the assembly of consonantal information can proceed regardless of the presence of vowels. If this assumption is correct, then evidence for inhibition should emerge even in words that do not contain any vowel letters. To examine the generality of the inhibition process in reading, we compared two types of targets that differ in the amount of vowel letters present in the script. One type of targets explicitly specifies most of the vowel information by vowel letters (explicit vowel targets), whereas the other type of targets omits most of the vowel information (implicit vowel targets). If consonantal information is sufficient for the assembly of phonology, then evidence for the inhibition should be independent of the presence of vowel letters. In the following section, we briefly review the results of two empirical studies examining these questions. A complete description of these results may be found in Berent (1993). The Assembly of Polygraphic Phonemes Results in the Inhibition of their Graphemic Competitors The primary goal of our first experiment is to demonstrate the existence of an inhibitory mechanism in Hebrew and determine its locus. An additional question concerns the generality of the inhibition in respect to the orthographic transparency of the target words and their frequency. To investigate these questions, we examined the effect of three types of masks (pseudohomophone, graphemic, and control masks) on the recognition of targets that contrast in terms of their frequency (high vs. low) and the presence of vowels (explicit vs. implicit). The results of this study are represented in Fig. 11.5. According to the lexical account, performance with the pseudohomophone should be at least as good as with the graphemic mask. In contrast, the sublexical account predicts inhibition in target recognition by the pseudohomophone. Contrary to the predictions of the lexical account, the masking of the target by its pseudohomophone resulted in a decrease of 5.3% in its recognition accuracy compared to its graphemic control. Furthermore, the magnitude of the inhibition caused by the pseudohomophone was similar across the two levels of word frequency (D = 4.43%, D = 6.6%, for high- and low-frequency words, respectively). The observation of such a general inhi-

Recognition accuracy as a function of mask type in Experiment 1. bition of target recognition by nonwords suggests that the locus of the inhibitory mechanism is in the sublexical connections between phonemes and graphemes. If the inhibition operates at a sublexical level of spelling assembly, then its presence may help detect the generality of phonological assembly in reading as well. Specifically, if the conversion of graphemes to phonemes occurs only in scripts in which the assembly of the word's phonology is highly predictable, then the inhibition should be limited to words containing vowel information. In contrast, if consonantal information is sufficient for assembly, then the inhibition should be obtained even when vowel information is absent. Supporting the general contribution of assembly to reading, the size of the inhibition effect was relatively unaffected by the presence of vowels in the scripts. The pseudohomophone mask resulted in an inhibition of 4.8% in the recognition of targets containing no vowel letters and 6% for targets in which some vowel information is present. The results of this experiment suggest the existence of an inhibitory mechanism between phonemes and their competitor graphemes in Hebrew. The fact that nonword orthographic stimuli can inhibit the recognition of targets containing competitor graphemes suggests that the inhibitory mechanism reflects generalized knowledge operating at a sublexical level of phonemegrapheme connections rather than specific lexical knowledge with the spelling of familiar words. The generality of the inhibition in respect to

the orthographic transparency of the script supports the idea that the assembly of phonemes in reading does not require the presence of vowels. Does the Inhibition Depend on the Presence of Vowels? The results of Experiment 1 suggest that the inhibition emerges even when the script permits the assembly of only a consonantal representation due to the absence of vowels in the script. The possibility that the assembly of phonology can be triggered by impoverished information containing exclusively consonantal information is intriguing. However, before accepting this conclusion, one may wish to rule out the possibility that the failure to observe a significant attenuation in the inhibition for words containing no vowel information may be simply due to the fact that the contrast between the two categories of targets in our experiment is insufficient. Specifically, it is possible that explicit-vowel targets did not differ from implicit-vowel targets because their vowel information was incomplete. For instance, the word ptish (ammer), pronounced /patish/ contains the explicit vowel /i/. However, the pronunciation of the first vowel is unspecified in the script. It can thus also be read as /patish/, /pitish/, /potish/, and /putish/. Hence, the failure to observe a stronger inhibition in the presence of vowels may be due to the failure to provide sufficient vowel information in the script. To reexamine the effect of vowels on the magnitude of the inhibition, we conducted a second experiment in which two types of targets were compared: one in which practically all vowel information was present and one in which most vowel information was absent. A second variable examined in this study was the length of the word. In general, one expects that the deleterious effect of competitor graphemes should be inversely related to word length because the shorter the word, the greater the relative contribution of each grapheme. To examine these questions, we compared four types of targets that contrasted in terms of the presence of vowel letters (implicit vs. explicit) and length (short vs. long) factors. The results of Experiment 2 replicated the finding of an inhibition in the recognition of target words by their graphemic competitors. The presentation of the pseudohomophone after the target resulted in a reduction of 10.46% in recognition accuracy compared to the graphemic control (see Fig. 11.6). However, this experiment provided stronger evidence for the modulation of the inhibitory effect by target characteristics (see Fig. 11.7). The size of the inhibition for targets containing explicit vowel letters (D = 12.75) was numerically greater than for targets in which vowel information is largely absent (7.8%). Thus, the size of the inhibition appears to increase in the presence of explicit vowels. Importantly, however, the data suggest that the presence of vowels may not be necessary for the emergence of the inhibition because the trend of inhibition was observed for both explicit and implicit vowel targets. A second factor affecting the size of the inhibition is

word length. The inhibition for short words was numerically larger than for longer words. Short words exhibited a significant inhibition of 14.58%, whereas the inhibition observed for longer words was a nonsignificant 6.24%. In summary, the present findings provide converging evidence that the activation of phonemes in reading Hebrew results in the inhibition of competitor graphemes. In addition, these results suggest that the size of the inhibition may be affected by the presence of vowels and word length. Because the inhibition for shorter words disrupts a greater proportion of the information required for target recognition, the inhibitory effect of the pseudohomophone is greater for shorter targets. Similarly, the presence of vowel letters seems to result in a numerical increase in the size of the inhibition effect for both short and long vowels. However, in accord with the findings of Experiment 1, the performance for short targets in the present study suggests that the presence of vowel letters may not be necessary for the emergence of the inhibition. Specifically, although the inhibition observed for the long, unvoweled targets was negligible (D = 2%), short words exhibited a pronounced inhibition effect regardless of the presence of vowels (D = 16%, D = 13%; for explicit-vowel and implicit-vowel targets, respectively). Further research is required to examine the generality of the inhibition for purely consonantal targets that are relatively long and for circumstances in which assembly is strongly discouraged due to the absence of any words specifying vowel information in the experimental list. Conclusions The existence of polygraphic consonants in Hebrew presents spellers with a severe ambiguity in assembling the spelling of many Hebrew words. To prevent the omission of spelling errors, spellers have developed an inhibitory mechanism whereby the activation of a polygraphic consonant results in the suppression of its competitor grapheme via an inhibition from the common phoneme. Our findings demonstrate the activation of such an inhibitory mechanism in the recognition of familiar words. Clearly, such a mechanism is required only if assembled spelling contributes to the recognition of the word. Thus, the inhibitory mechanism is prima facie evidence that skilled spellers assemble a graphemic representation in spelling familiar Hebrew words. In addition, this mechanism provides a definition of skilled spelling in Hebrew. Although the consultation of word-specific knowledge seems necessary to support skilled spelling in such a deep orthography, this source of knowledge is insufficient for skilled spelling. The assembly of words' spelling appears to be an important source of constraint even in the recognition of familiar words. Thus, skilled Hebrew spelling entails recognizing the potential sources of ambiguity in spelling Hebrew words and automatically preventing the effect of misleading information through inhibition.

Supporting the automaticity of spelling assembly in Hebrew is evidence for inhibition that is observed in a task that clearly does not require the activation of a word's spelling: reading. This fact has several important implications. One concerns the role of phonology in reading Hebrew. Because the inhibition originates at the level of phoneme-grapheme mapping, the emergence of an inhibition necessarily indicates the contribution of an assembled phonological representation to reading. Thus, indirectly, these results also support the role of assembled phonology in recognizing Hebrew words. Furthermore, the fact that evidence for inhibition emerges even for targets containing no explicit vowels suggests that consonant phonemes can be assembled regardless of the presence of vowels. Consonant phonology thus constrains reading even in an extremely deep orthography. The question of whether assembled phonology constrains reading in deep orthographies is subject to much debate in the word recognition literature (cf. Baluch & Besner, 1991; Frost, 1994). However, existing evidence for the contribution of assembled phonology in the Hebrew word recognition literature comes from studies examining the effects of the presentation of vowel information on the ease of target recognition (Bentin & Frost, 1987; Frost, 1994, 1995; Frost, Katz, & Bentin, 1987; Koriat, 1984, 1985; Navon & Shimron, 1981). These studies generally suggest that the presence of vowel information facilitates target processing. In effect, these findings amount to the suggestion that the reduction in the orthographic depth of the script facilitates recognition. This conclusion, however, leaves open the question of whether assembly can take place even for an extremely impoverished script containing consonantal information alone. Our finding that the inhibition emerges for targets lacking any vowel information suggests that consonant information is sufficient to trigger the process of assembly (Berent & Perfetti, 1995), and that such a process constrains the recognition of printed Hebrew words. The sufficiency of consonantal information for assembly has some interesting implications regarding the structure of graphemic and phonemic representations. So far we have discussed skilled spelling in Hebrew exclusively from a processing point of view. We have identified two processing strategies for obtaining the spelling of the word and its phonology, and we have examined their contribution to the process of spelling and reading Hebrew words. However, in addition to these processing questions, a theory of skilled spelling and reading requires an account of the structure of the representation used by skilled spellers and readers as well. Of particular interest is whether such a representation is subject to some universal constraints and whether some of these constraints are linguistic in nature. Caramazza and Miceli (1990) suggested that graphemic representations distinguish between consonants and vowels by representing them on two distinct planes. Such a representation is supported by several case studies of Italian patients exhibiting

specific impairment of vowel processing (Caramazza & Miceli, 1990; Cubelli, 1991). The possibility that consonants and vowels may be two distinct entities in assembled representations is further supported by the distinction in the processing characteristics of consonants and vowels in assembling a phonological representation of English words (Berent & Perfetti, 1995). This distinction is attributed to the presence of a universal linguistic constraint on reading that assigns consonants and vowels into two distinct constituents, or planes, in phonological representations. Indeed, a distinction between consonant processing and vowel processing emerges in several areas related to the processing of linguistic input, such as speech perception and production (Fowler, 1980, 1983; Fowler & Smith, 1986), language acquisition (Macken, 1979, 1992; Studdert-Kennedy & Whitney Goodell, 1992), spelling (Caramazza & Miceli, 1990; Cubelli, 1991), and reading (Berent & Perfetti, 1995). If consonants and vowels are two distinct constituents in the assembly of both spelling and phonology, then one expects that, given a language in which such a distinction is strongly supported by the morphology and is further represented in the writing system, readers and spellers might be able to assemble the consonant constituent in the absence of the vowel constituent. This proposal is compatible with our present results. The emergence of the inhibition for targets containing no vowel letters suggests that such targets can support the assembly of consonantal phonology and spelling even when the target word lacks specification of the vowels. Finally, perhaps the most important implication of our findings concerns the relations between the assembly of phonology and spelling. The fact that the assembly of phonology is constrained by inconsistencies inherent in the mapping of phonemes to graphemes indicates that these two mapping functions, graphemes to phonemes and phonemes to graphemes, are not independent. Our findings suggest that the assembly process is bidirectional: The activation of one end of the mapping functions, graphemes to phonemes, automatically triggers the other, phonemes to graphemes (see also Stone et al., in press). Each end of the mapping function is exposed to the effect of inconsistencies in the other. These results suggest close relations between theories of spelling and reading: The assembly of phonemes and graphemes are two faces of a single coin. These processes are bidirectional and highly interactive. It seems impossible to account for one of these processes independently of the other.

Chapter 12 Children's Use of Analogy in Learning to Read and to Spell Jean Emile Gombert Université de Bourgogne Peter Bryant University of Oxford Nicola Warrick University of Oxford The Orthographic Neighborhood Effect in Reading Knowledge that the reader already has about the pronunciation of words may influence the way written words (or pronounceable pseudowords) are pronounced when encountered for the first time during the reading process. It is clear that adults and children often employ analogies that are based on orthographic neighborhoods when trying to decipher new words. Glushko (1979) found that American adults, when reading pseudowords, did not always follow the grapheme-phoneme conversion rules; they sometimes used analogies to the pronunciation of irregular words (see Baron, 1977; Brown & Besner, 1987; Masterson, 1985). The same results were obtained in French by Peereman (1991) and in Spanish by Sebastián-Gallés (1991). Taken together, these results suggest that, contrary to what was claimed in some theories (Bentin, Bargai, & Katz, 1984; Bentin & Frost, 1987; Feldman & Turvey, 1983; Frost, Katz, & Bentin, 1987; Katz & Feldman, 1983), the reading mechanisms for languages with shallow and deep orthographies are not different. In fact, the use of analogies appears early during the process of learning to read. In a cross-linguistic study, Goswami, Gombert, and Fraca de Barrera

(in press) compiled two lists of monosyllabic pseudowords and two lists of bisyllabic pseudowords in English, French, and Spanish. In each language, one list was composed of pseudowords that had many real word neighbors when the first letter was changed (for instance, in English, voop or ketter) and one list was composed of pseudowords with few orthographic neighbors (joog or terket). The participants were children, from Grades 2, 3, and 4, and adults. They had to read the lists aloud quickly and without errors. Whatever the language, the age and the item length, the pseudowords that had several real words as neighbors were read faster and with fewer errors than the others. This effect was stronger in English than in French and stronger in French than in Spanish. This order of difficulty is probably a consequence of the fact that the more irregular the orthography, the more analogies help the reader. On the whole, this effect is stable across the ages in all three languages. Thus, the use of analogy in reading already seems to be effective by the second year of learning to read. It is not enough to establish the early use of analogy. It is also necessary to specify how this employment of lexical knowledge works. In fact, there are two possibilities. The first is that the reader uses links to long-term memory between certain spelling patterns and the pronunciation of these patterns. The second is the simple use of some phonological patterns in memory for known words, which facilitates the pronunciation of all items, including these phonological patterns, whatever the reason for this pronunciation, and does not take into account the orthography of the written counterparts of these items. Let us take as an example the ease with which English readers can read the pseudoword ketter. According to the first hypothesis, they manage to do this because they are already familiar with the letter sequence etter and the sound that it usually represents because they have seen it frequently in the words better, letter, and wetter. According to the second hypothesis, they read the word ketter quite easily because they are familiar with pronouncing and hearing the sound [etor *]: It is this familiarity rather than the familiarity of the letter pattern that helps them to read the pseudoword. To decide between these two possibilities (which are not incompatible), Goswami, Gombert, and Fraca de Barrera (in press) used lists of pseudowords that had numerous phonological neighbors (by changing the first phoneme) but few orthographic neighbors. In fact, these items were pseudowords that were homophones to orthographic neighbors of real words (for instance, real word = coffee; orthographic neighbor O + P+ = loffee; phonological neighbor O - P+ = loffi). If the first hypothesis is true (orthographic neighborhood effect), orthographic neighbors (in fact orthographic and phonological neighbors O + P+) are read more easily than phonological-only neighbors (O - P+). This was very much the case in English: Whatever the age, the O + P + items were read faster

(1.14 sec. vs. 1.41 sec.) and more accurately (correct reading = 80% vs. 68%) than the O - P+ items. In French, this phenomenon also occurred whatever the age, but the effect was not as strong as in English (reading times: 1.00 sec. vs. 1.07 sec.; correct reading = 92% vs. 87%). As for Spanish, the comparison was impossible. In a language with a shallow orthography, it is difficult to find different spelling patterns for the same pronunciation. The second hypothesis implies that phonological-only neighbor items (O - P+) are read more easily than pseudowords with few neighbors (either orthographic or phonological neighbors: O - P-). This second hypothesis was also clearly validated in French (reading times: 1.18 sec. vs. 1.41 sec.; correct reading = 83% vs. 73%). In fact, it seems that in French, there is a simultaneous use of orthographic analogy in reading aloud and a facilitation of pronunciation through the use of a phonological code when items to be pronounced share large phonological patterns with known words. In English, there were the same kinds of results. Whereas the orthographic neighborhood effect was stronger in English than in French, the effect of the simple phonological neighborhood was smaller. As a matter of fact, in the English group, this effect was statistically significant only in children and only for the number of accurate readings (for children, whatever the age: 51% vs. 45%) but not for reading times (1.77 sec. vs. 1.81 sec.). In fact, it seems that, in English more than in French, the phonological-only neighbor pseudowords are, orthographically speaking, bizarre items. This oddity could be the source of a negative effect that cancels the positive effect of having a phonological output code for pronouncing these items. Analogical Processes in Learning to Read Whatever form the simple phonological neighborhood effect takes, this series of experiments established that, as early as the second year of practice, the reader takes into account the orthographic neighborhood of the items met during reading. So, we must determine more precisely when this phenomenon occurs in the learning process. There are two opposing views. For some researchers, the phenomenon comes late; it occurs only after the beginning reader has already mastered graphemephoneme correspondences. For others, it occurs precociously and might allow beginning readers to read words that they have never met before, when they are not yet able to decode these words. Most of the developmental models that treat the acquisition of reading as a sequence of stages agree with the first view. In one of the most famous, Frith (1985) postulated a development in three successive stages. In the first stage, the logographic stage, the absolute beginner develops strategies in order to "guess" the oral words corresponding to the visual patterns that he or she perceives but does not yet know how to read. These strategies consist of

page_224
next page > Page 224
taking all the clues that, in the given context, can help with the identification of the word. These could be the advertising logo that is characteristic of certain words (for instance, Coca Cola), or they can also be some salient visual clues taken from the word itself, for instance, some particular features (such as the point above i), and some letters or patterns of letters. At the extreme, these known letter patterns taken as a clue can include the whole word that is recognized "by heart," globally. Nevertheless, even in such a case, its component letters can't be used in order to read other words. This pseudoreading, in which the beginner uses all the available clues in order to guess the word, would permit the recognition of a limited number of words (probably less than 100), not by direct access to the internal lexicon but by using a pictorial semantic system (Morton, 1990). In this system, first the concept corresponding to the written word is accessed without any linguistic processing, and then the spoken word corresponding to the concept is activated. Written linguistic information is processed as nonlinguistic material, and the relations between written configuration and meaning do not depend on general linguistic rules. In the second stage, the alphabetic stage, the main phenomenon is the use of phonological mediation. At this level of learning, the attentional effort is principally devoted to matching written and spoken linguistic forms. This matching requires the use of the rules of grapheme-phoneme correspondence (GPC) that depends on knowledge of the alphabet, a metaphonological awareness of the phonemic unit, and a linkage between these two types of knowledge. Last, in the third stage, the orthographic stage, which will become the stage of automated reading expertise, words are analyzed in orthographic units without the systematic use of phonological conversion, and this development allows the reading of irregular words. From this point of view, the use of analogies does not appear before the alphabetic stage and constitutes a sophistication of the matching between writing and oral language by using orthographic units larger than the phoneme, in which the reader has noted the regularity. This analysis does not fit with some experimental data that have shown a more precocious use of analogies in reading. In fact, it is likely that the process of using analogies between words in reading has to be considered as a part of beginning reading and not simply as a special case of alphabetic processes. The hypothesis is that, in order to read words that they have never seen before in written form, beginning readers use their knowledge of orthographic patterns in words that they can already read. For instance, a child who can read the word light might read the words night or sight by using, on the one hand, the orthographic analogy between these words and, on the other hand, his or her own ability to recognize the rime /ait/ in these three words. The same phenomenon works for clusters of consonants at
< previous page

next page >
< previous page
page_225
next page > Page 225
the beginning of words (the onset) but less (or only later) for units other than the onset or the rime. Without special training, young children seem unable to break a word into its constituent phonemes, but they are quite good at producing (Dowker, 1989) and detecting (Bryant, Bradley, MacLean, & Crossland, 1989) rhymes and alliteration. That means that they can judge that words and syllables, which are clearly different from each other, but, nevertheless, have phonological segments in common. These common segments in rhyming tasks are usually larger than the phoneme in that they typically contain more than one phoneme. For example, the rhyming sound in cat and hat is /at/, which is two phonemes. The ability to detect rhyme is probably a great deal less refined than the ability to detect phonemes. The developmental relation between judgments about rhyme, alliteration, and phonemes and the acquisition of reading is an intriguing one. One of the best measures of rhyme detection and of phoneme detection is an oddity task. Children hear three or four words at a time and are told that all but one rhyme, or that all but one begin with the same phoneme or end with the same phoneme. It is not surprising that young children can manage the rhyming oddity task quite well long before they learn to read. It is rather more interesting to note (Kirtley, Bryant, MacLean, & Bradley, 1989) that 5-year-old nonreaders also do quite well (and well above chance level) when asked to detect the word that begins with a different phoneme from the rest (an alliteration task). The difficult task for them is to judge which word ends with the same phoneme. Five-year-old children who have not yet learned to read are at chance level in this task, whereas those who have learned to read do better than this. Even prereaders detect rhyme and alliteration quite well. Sometimes this even means that they rise above chance level in phoneme detection tasks, but other phoneme detection tasks flummox them, and they are plainly unable to fully analyze the phonemes in most words. This leaves us with the question of whether these early rhyme and alliteration skills have anything to do with reading. Given as a postulate the idea that the important phonological link in reading is the grapheme-phoneme correspondence, it is quite reasonable to suggest that rhyme at any rate should be quite trivial as far as reading is concerned. Rhyme is too "gross," too "global," as Content, Morais, Alegria, and Bertelson (1982) put it. However, there is another possibility, which is that children do not learn just about relations between single letters and phonemes. For example, the letter sequence -ight represents, in a relatively invariant way, a sound that contains more than one phoneme. What is to stop the child learning an association at this level? The answer, it seems, is "nothing at all." This certainly is the conclusion to be drawn from some interesting experiments by Goswami (1986), which
< previous page
page_225
next page >
< previous page
page_226
next page > Page 226
showed that beginning readers are often quite eager to associate sounds with letter sequences of this sort. Goswami gave 6-, 7-, and 8-year-old children a set of words to read that were mostly too difficult for them. Then she told them what one of these written words (e.g., beak) meant. The result of her telling them how to read this word was that it helped them to read other rhyming words with similar final spelling patterns, such as peak, leak, and weak, but it had little effect on their ability to read other words such as bean or bake, which did not share the same final spelling sequence or rhyming sound. Later, Goswami (1988a) repeated this striking finding with a task in which children had to read passages of prose. Bruck and Treiman (1992) showed that training to use rime analogy (e.g., pig, big) is more efficient than training to use other analogies (e.g., pig, pim) in order to help beginning readers to read new words that were presented just after the training session. If children are ready right at the start of learning to read to infer that two words that end with the same spelling sequence also share a rhyming sound, it is quite likely that their ability to group words by rhyme should help them to learn to read and to spell. In fact, there is ample evidence for this connection. Children's early (preschool) sensitivity to rhyme and alliteration is an extremely powerful predictor of their eventual success in learning to read. It is also the case that training in rhyme helps children learn to read (Bradley & Bryant, 1983). These data are important for the question of knowing if the link between phonological skills and reading is continuous or discontinuous (cf. Bryant, 1993). The first possibility is that the development here is a continuous one (Bryant & Goswami, 1987; Goswami & Bryant, 1990). Children acquire certain phonological skills and presumably become more skilled phonologically throughout the preschool period, and these early phonological skills form the basis of their learning about lettersound relations when they begin to read. The other possibility (Content et al., 1982) is that the phonological routines that they have to learn about in reading are at a different level and take a completely different form to any phonological analyses that they have carried out until then. According to this second argument, children acquire new phonological skills, which otherwise would not be a part of their cognitive repertoire, as a direct result of learning to read. The view on this continuity/discontinuity depends on the phonological unit that you think is important. If you hold the view that the crucial unit is the phoneme and the crucial link the grapheme-phoneme correspondence, then you will probably hold to a discontinuity position. If, on the other hand, you agree that children probably also learn that words that rhyme also have sequences of letters in common, the idea of continuity is bound to seem the more plausible one. In fact, the evidence for the importance of rhyme and for its links with later success in reading seems so
< previous page

page_227
next page > Page 227
compelling that some version of the continuity position seems inescapable. Children's sensitivity to rhyme certainly feeds into the process of learning to read, but the experience of reading probably leads to the acquisition of entirely new skills. Explicit attention to phonemes is one. What seems to be well established in this research is the precocious role of analogical processes. The fact that onsets and rimes play a role of special importance in these analogies still has to be proved. In fact, it is possible that this phenomenon is peculiar to the English language, where the pronunciation of vowels depends on the subsequent consonants and where the spelling patterns corresponding to the rimes are often so complicated that it is cognitively less costly to encode them as a block than to analyze them. Moreover, even in English, Goswami (1991b) failed to reproduce the advantage for the rime in precocious analogies when children had to read words included in texts rather than isolated words. In the same way, Bruck and Treiman (1992) showed that the primacy of the rime exists only during a short period. As soon as the day after, training with analogies other than rimes produces better results as a help in reading new words (see Wise, Olson, & Treiman, 1990). This result does not invalidate the hypothesis that onset-rime analysis is the first type of syllable analysis by prereaders. On the contrary, the authors suggest that it is because this type of analysis is very easy for children that they are less likely to remember the training than when it involved the use of analogies involving other intrasyllabic units, the identification of which was far more difficult due to its more explicit nature. Muter, Snowling, and Taylor (1994) showed that, although 6-year-old children, trained on a series of clue words, read more words that shared spelling patterns with the clue words than control words, this effect was reduced when the clue word was not exposed during the presentation of the targets. These data invite a new description of the process of learning to read and of the role of analogies in this learning process (see Fig. 12.1). At first, beginners who have already met written words in their prelearning activities are able to take advantage of two forms of knowledge: (a) visual knowledge that allows them to guess a certain number of written words that they have met repeatedly before; and (b) phonological knowledge gained from the manipulation of oral language, knowledge that notably includes a sensitivity to the composite nature of syllables, as shown by the precocious sensitivity of the children to rimes and, to a lesser extent, alliterations. As with any set of words, the words that are identified (guessed) by a visual procedure include a certain number of orthographic regularities, which can be noticed by the visual information processing system. These orthographic regularities are, themselves, in systematic co-occurrence with phonological regularities in the pronunciation of these words. It is this correspondence between orthographic analogy and phonological analogy that is used by the cognitive system in a self-learning mechanism in order

Fig. 12.1. The learning to read process. to allow the reading of some new words that are phonological neighbors of already known words. At first, there is no reason that the reader must have any awareness of the analogies made between spelling patterns and between spoken words. In fact, in a recent study, Seymour and Evans (1994) showed that it is later on that the child becomes able to perform conscious, intrasyllabic analysis. Complementary evidence comes from Cardoso-Martins (1994) who, in comparing performance on different rhyme categorization tasks in kindergartners and first graders, provided results that suggest that rhyme detection does not involve attention to segments. She concludes that this kind of
< previous page

page_229
next page > Page 229
intrasyllabic manipulation may best be described in terms of sensitivity to some sort of global phonological similarity. Nevertheless, the repeated use of analogies in beginning reading implies an increase in the saliency of the orthographic and phonological configurations they involve and, thereby, improves their availability for conscious access. The mastery of the alphabetic code has a double origin. First, it is the issue of a progressive refinement of the analogies the child makes until taking into account the minimal orthographic unit (cf. Goswami, 1993). Second, it is a consequence of instruction that helps and, for many children, allows this refinement. The mastery of the alphabetic code implies a conscious awareness of the units in the code. This way of describing reading acquisition is very different from previous descriptions. Here, the prereading processing, that we call pictorial and that is usually referred to as logographic (an ambiguous term in our sense), is not optional. It is necessary for the subsequent building of orthographic knowledge. This orthographic knowledge is the product of the analyses that children apply to the words that they are able to identify visually, especially given the way that their phonological knowledge of these words is organized in memory. Thus, such a visual vocabulary is indispensable for allowing entry into reading. This pictorial processing is destined to disappear. As a matter of fact, learning to read leads to the establishment of analogical, alphabetic, and orthographic processes that are automatically activated when the skilled reader meets a written word. These reading processes are the product of the transformation of the prereading processing that no longer exists in competent readers. It is impossible to recognize stages in this evolution. In fact, the driving force of this evolution is the confrontation with written words. The consequence is that the evolution is dependent on the frequency of encountering different words. The décalage (split) in functioning levels (succession: prereading, analogical reading, alphabetic reading, and orthographic reading, with the latter three being combined) as a function of the words to be read is the rule during the first months (or perhaps years) of learning to read. The view presented here provides a way of explaining interindividual differences. It is enough to consider the possibility of interindividual differences in phonological or visual skills to explain why one reader develops some processing skills more rapidly than another. Analogical Processes in Learning to Spell The model proposed by Frith (1985) is not just a model of reading development but a model of reading and writing development. In this model, there is both a parallelism and an evolving functional difference between reading

and spelling. The logographic stage occurs with reading before writing, but it lasts longer, so reading is still logographic when writing is already alphabetic. The children's experience of logographic reading eventually helps them to use the same code more effectively when they write. In contrast, the nature of writing where letters are written one by one, leads children to use the alphabetic code, and their experience of spelling words alphabetically has the effect of showing them how to read alphabetically as well. The alphabetic stage occurs in spelling before reading, but it lasts longer. Spelling is still alphabetic when reading has become orthographic. Children use the orthographic code first when they read and later when they spell. Goswami and Bryant (1990) had two concerns about this model. First, they pointed out that there is no evidence that children spell logographically before they spell alphabetically. Second, they thought the model to be unsatisfactory because it is vague about the effects of skills, particularly phonological skills, which children acquire before they learn to read and spell. Of course, one question arises about the role of analogies in spelling acquisition. Goswami and Bryant argued that analogies must be important in spelling because they are based on phonology, and phonology plays a stronger role in learners' spelling than in their reading. From this logical argument, these authors derived the hypothesis that, when reading unfamiliar words, children also make analogies about phonological units when they try to spell a word for the first time. A study by Campbell (1985) seemed to contradict this hypothesis. Her study used a priming paradigm with children from 9- to 12-years-old. Each child had to write only the pseudowords included in a dictated list in which there were real words and pseudowords. The primes varied for the participants. For half of the children, each target pseudoword was preceded by a certain rhyming real word (e.g., [boup] was preceded by soap); for the remaining half, the same pseudowords were preceded by other real words (e.g., [boup] was preceded by rope). Only the participants who had a reading age of 11 years or more consistently spelled the pseudowords using the spelling pattern of the prime, confirming that they used similarities of sound to make analogies about spelling. However, the fact that the younger participants in Campbell's study used analogies infrequently when faced with pseudowords does not imply that they were totally unable to use analogies in the normal course of spelling. Goswami (1988b) presented 6-year-olds some written words (e.g., beak) and pronounced those words. Then the children had to spell other words. Some of these other words sounded similar to the clue word (e.g., peak or bean); others did not (e.g., lake or bask). The children spelled the former (the analogy words) better than the latter (control words). Moreover, the children correctly spelled the analogy words that shared a rime with the
< previous page
page_230
next page >
< previous page
page_231
next page > Page 231
clue word (beak/peak) more often than the words that shared the initial consonant-vowel segment (beak/bean). Thus, in spelling as well as in reading, children seem able to use analogies; analogies based on rime seem easier than those not based on the onset/rime structure of the syllable. Nation and Hulme (1994) had slightly different results. They also showed that 6-year-old children can make analogies between a visible clue word and a similar sounding target when spelling. However, in their data, the use of analogy was not any stronger with words sharing rimes than with words sharing other phonological segments. There was the same rate of analogy use when the clue and the target shared a rime, an initial CV-segment, or a vowel. Nevertheless, analogies were not made when the clue and the target shared only common letters. The same pattern of results was obtained when the clue word was not visible (i.e., using a priming experimental paradigm). Thus, as with beginning readers, it seems that beginning writers can make analogies in spelling, but it is not clearly established that the rime unit plays a special role for such analogies. Moreover, apart from the cases in which children are prereaders, in the experiments on the use of analogies in reading and spelling, the level of learning is generally defined in a very rough way. All we know is that, for example, the beginners are in their first year of learning to read and to spell. This lack of precision might obscure some developmental changes during that first year of learning. Sprenger-Charolles and Casalis (1996) tested the use of analogies in reading and spelling by French beginning readers 4 and 9 months after starting to learn to read and spell. The results revealed that analogies are used as early as the first session in reading but only at the second session in spelling. This difference between reading and spelling was also found in Coenen's (1994) results concerning children learning to read and to spell Dutch (a language with a rather transparent orthography) that showed that word-specific knowledge is used in reading before spelling. On the whole, these recent results do not contradict Goswami's (1988b) claim that children use their reading knowledge in order to decide if one analogy is appropriate in spelling. The directionality of this link implies that analogy processes occur first in reading then in spelling. This difference between reading and spelling is not surprising. As a matter of fact, there is a big difference between reading and spelling tasks as far as the memory is concerned. Reading a word implies recognizing the written patterns; spelling a word implies recalling the orthographic sequence. It is likely that, in recognition, a global apperception is cognitively less costly than an analysis of the pattern. In contrast, the quality of recall necessary to be able to reproduce what is recalled implies a precise identification of each successive letter. In such a context, an analytical treatment of the spoken word in an alphabetic manner and an activation of the successive letters to be written is,
< previous page

next page >

page_232
next page > Page 232
cognitively speaking, more economical than the activation of a complicated configuration that has to be maintained in working memory until its graphic transcription is completed (a long process in beginners). This processing difference might explain why, usually (i.e., without special teaching), the ability to segment by phonemes is only a consequence of learning to read but is necessary for spelling (Goswami & Bryant, 1990). Conclusion Almost everybody agrees with the idea that analogies are used at some level of learning to read and to spell. The controversy concerns the timing of this use. In fact, this debate is part of a more general debate on analogical reasoning in children. Whereas some people taking a Piagetian perspective suggest that this kind of reasoning is late developing (cf. Inhelder & Piaget, 1958), others think that it appears early (cf. Brown, 1989). Goswami (1991a) resolved this contradiction by proposing an analogical development that allows early analogical competence and that also postulates the later development of metalogical skills. Learning to read and to spell is the acquisition of knowledge in a formal domain, and, as in other acquisitions of this sort, it is likely that analogy plays a central role (cf. Halford, 1992; Suzuki, 1994). The written environment, as with other learning environments, is a very complex one, and so it is difficult, and perhaps impossible, for the beginner to fully understand the relevance of the rules the teacher tries to explain. Analogical processes permit the beginner to go beyond his or her own explicit knowledge in apprehending written material. This kind of functioning is efficient first in reading; because of memory load it appears in spelling only later when the child is able to produce each graphic unit to be used in the spelling pattern to be written. The existence of early analogical processes in learning to read does not contradict the idea that other analogical processes can appear later as a consequence of alphabetic reading experience. The development of orthographic knowledge through alphabetic reading, and above all spelling, adds to the basis of knowledge available for making analogies. Therefore, it is not astonishing that analogy use seems to be more frequent in skilled readers than in beginners. The important point is to recognize that the early occurrence of analogies in learning to read and to spell provides a way of explaining how an information processing system, which can neither read nor activate written concepts to be graphically reproduced (as that system exists in prereaders), can be transformed into a reading and spelling machine. This view implies the affirmation of the universal character of this way of learning to read and to spell. As shown by the results of Goswami et al.

(in press), and as suggested by those of Wimmer and Goswami (1994) and by the analysis of Goswami (1993), what is different, depending on the degree of transparency of the orthographies, is more the visibility of the analogical processing than its existence. If you imagine a written system in which every word is a consonant-vowel monosyllabic word, there is no visible difference between analogical and alphabetic reading. Nevertheless, these two ways of reading remain, psychologically speaking, different. References Baron, J. (1977). What we might know about orthographic rules. In S.

Chapter 13 Learning to Read and Learning to Spell are One and the Same, Almost Linnea C. Ehri City University of New York Graduate School Over the years, I have conducted several studies investigating how children learn to read words. I designed these studies to include information about students' memory for spellings of the words they learned to read in the belief that I was studying more general word learning processes in which treatments would influence spelling as well as reading. Results of these studies confirmed my belief. The purpose of this chapter is to consider the relationship between reading and spelling. A conceptual framework distinguishing the important behaviors, processes, and types of knowledge is presented. Similarities and differences between reading and spelling concepts and phenomena are examined to achieve a clearer understanding of how reading and spelling are linked during development. Various studies are examined for evidence bearing on these relationships. I build a partly theoretical, partly empirical case for the claim that learning to read and learning to spell are one and the same, almost.1 1 My presentation does not include a comprehensive review of the literature on this topic. I apologize to researchers who have published relevant findings that are not cited. The space available precluded such a treatment. The research cited to support claims is thought to be consistent with other research not cited. I welcome being notified of discrepant findings I have overlooked. In constructing my case, I have tried to adopt straightforward language and to avoid terms that have become ambiguous as a result of researchers using them to mean different things (the term orthographic is one of these) as Wagner and Barker (1994) note. More precise terms replace this term.

Reading and Spelling: Conceptual Ambiguities and Overlap The English language includes two terms, reading and spelling, that are used by researchers and teachers to divide the world. Researchers classify studies into those focused on reading, those focused on spelling, and those focused on relations between reading and spelling. Teachers plan lessons to teach reading during one period and different lessons to teach spelling during another period of the school day. All of this presumes that there are two separate things that are being studied or taught. It is important to consider to what extent our language reflects reality. Examination of the term spelling reveals that it is ambiguous in ways that muddy the distinction between reading and spelling. The first meaning of spelling that probably jumps to mind is the act of spelling a word by writing it. However, spelling can also function as a noun to refer to the product that is written, the word's spelling, consisting of a sequence of letters. Spellings of words are the targets not only of spelling behavior but also of reading behavior. Talk about spellings of words for reading blurs the separation between reading and spelling. Another factor blurring the distinction is that there are two types of spelling acts. Being able to spell may refer to being able to write out the spellings of words correctly. However, it may also mean being able to recognize whether words are spelled correctly or incorrectly as the words are being read. Spelling-recognition tasks as well as spelling-production tasks are commonly used to measure spelling ability. For example, in a task designed by Olson, Kliegl, Davidson, and Foltz (1985) and used by many researchers, participants are required to read several pairs of identically pronounced words such as RAIN and RANE and decide which is the correct spelling. Categorizing this as a spelling task rather than a reading task is arguable. Cleverly, Olson et al. have avoided the issue by labeling this task orthographic coding. Even the act of spelling words by writing them is not pure. Most spellers write out words and then read the words to verify their correctness. To the extent that spellers do this when they spell, reading as well as spelling contribute to the final spelling product. The upshot of these considerations is to raise doubt that reading and spelling are different. People read spellings of words. People spell spellings of words. People read the spellings they have spelled. The lack of a clear distinction between these terms raises the possibility that we have been misled by our language and that reading and spelling are more similar than we recognize.

Reading and Spelling: Basic Concepts and Processes Although the ambiguity and overlap in the meanings of these terms might appear to be hopeless, some basic distinctions can be salvaged. Words have spellings, that is, prescribed sequences of letters. Spellings are the targets of two basic literacy acts involving words: (a) reading spellings in order to determine their pronunciations and meanings; (b) spelling spellings by writing them. A third literacy act can be derived from the first. The act of reading spellings includes noticing whether they are spelled correctly. That readers do this spontaneously in the course of reading words was revealed in a study by McConkie and Zola (1981). They recorded readers' eye movements and documented their sensitivity to subtly misspelled words embedded in the text they were reading. For example, they found that readers' normal eye-movement pattern was disrupted when they saw ''fracture'' misspelled as FRAOTURE. I refer to this as the act of recognizing misspellings. Tasks requiring students to recognize misspellings of words include multiple-choice spelling recognition tests, proofreading tasks, and dictation tasks in which a spelling just written is checked to verify its correctness. How are reading and spelling phenomena similar and different? In order to draw comparisons, we need to lay out a conceptual framework that distinguishes and incorporates the various behaviors, processes, and knowledge sources that appear to be central. Constituents of the framework are introduced in this section, incorporated into a table, and then discussed more fully. 1. Familiarity of spellings. In learning to read and spell, students encounter words whose spellings are familiar because the forms have been processed on previous occasions and remembered. They also encounter words whose spellings are unfamiliar because they have not been seen and remembered. 2. Types of knowledge about spellings. In learning to read and spell, students acquire two types of knowledge that they hold in memory and use to read and spell words: (a) knowledge about the general spelling system, including such regularities as how graphemes correspond to phonemes across many words; (b) knowledge about the spellings of specific words that have become sufficiently familiar to be stored in memory. 3. Types of literacy acts involving words. As indicated previously, three types of literacy acts can be distinguished: (a) reading words to identify their pronunciations and meanings, (b) producing spellings of words, and (c) recognizing whether words are correctly spelled or misspelled.

4. Ways to process words. There are at least three ways to process words in order to read or spell them: by memory, by invention, by analogy: (a) Words can be processed by accessing information stored in memory from previous experiences with those specific words. Familiar words are processed in this way; (b) words can be processed by invention, that is, by assembling pronunciations from letters to decode the words or by generating letters that are plausible symbols of pronunciations to spell words; (c) words can be processed by analogizing to known words. Either invention or analogy may be used to process unfamiliar words.2 The three ways of processing words may be used to either read words, produce spellings of words, or recognize misspellings. 5. Levels of development. To describe development, researchers have distinguished several developmental levels, referred to as stages or phases. These levels have been proposed to account for word-reading development and word-spelling development separately. However, the labels and the underlying processes turn out to be very similar. Both sets of labels refer to the predominate type of knowledge about the alphabetic system that students use to remember the forms of familiar words and to invent readings or spellings of unfamiliar words. Level 1 (prealphabetic) applies to prereaders who operate with nonalphabetic information because they know little about the alphabetic system. Level 2 (partial alphabetic) applies to novice beginners who operate with rudimentary knowledge of some letter-sound relations. Level 3 (full alphabetic) applies to students who possess more complete knowledge involving grapheme-phoneme units and how these units form words. Level 4 (consolidated alphabetic) applies to more advanced students who have knowledge of letter patterns as well as grapheme-phoneme units.3 The various concepts previously distinguished are incorporated into Table 13.1 to lay out the processes, knowledge sources, and behaviors com2 There is another way to read unfamiliar words besides the two ways considered here. When unfamiliar words are encountered in meaningful contexts, readers may predict the words by using contextual cues, or partial graphophonic cues, or a combination of both. For example, in the context of discussing various types of dinosaurs in a book, readers might predict that an unfamiliar word known in speech but not in print is "brontosaurus" based on the topic of the text, an adjacent picture, seeing b at the beginning of the word, or a combination of these cues. This form of invention used in reading words in text appears to have no parallel in spelling words, so it is not considered here. 3 Conceptualizations of these levels differ among researchers. Some differences involve issues about where boundaries should be drawn, what the levels should be called, and what phenomena should be included at each level. Some researchers distinguish additional levels beyond Level 4. My purpose here is to focus on basic distinctions that expose similarities between the levels proposed for reading and those proposed for spelling and to overlook more fine-grained differences.

prising reading and spelling domains to reveal their similarities. These processes are now considered in more detail. Familiar Versus Unfamiliar Spellings of Words The basic unit of print in English is the word. Whereas smaller units of print, principally graphemes symbolizing phonemes, may vary in different contexts, the spellings of specific words remain constant. The major task in learning to read and spell is to become sufficiently familiar with the spellings of words so that information about their letters is retained in memory and enables them to be read or spelled easily. Beginners must feel overwhelmed by the number of written words that are not familiar, whereas highly literate adults may feel surprised if they come across words they have never seen before unless the word is a new vocabulary item. Findings of several studies show that learners do remember the written forms of specific words. Ehri (1980) found that beginners stored the spellings of specific words they learned to read in memory rather than alternative, phonetically equivalent spellings. Reitsma (1983) showed that first graders needed as few as four practices to retain letter information about specific words in memory. Ehri and Saltmarsh (1995) found that advanced beginners who had practiced reading words several times retained fairly complete letter information when tested 3 days later. I have portrayed word familiarity as a bipolar concept in order to distinguish words that readers have seen before and retained in memory from words they have not. Among beginning readers, this is an important distinction. However, as students gain more experience with a greater number of words, it becomes important to distinguish degrees of familiarity among the words that are familiar. The many studies documenting strong word frequency effects on reading and spelling performances verify the importance of conceptualizing word familiarity as a continuum. Sources of Knowledge About Word Spellings Held in Memory At the heart of reading and spelling is knowledge about the spellings of words. Two types of knowledge have been distinguished: People possess knowledge about the general alphabetic system, that is, spelling regularities that recur across many different words, including grapheme-phoneme and phoneme-grapheme units and various types of spelling patterns; people also possess knowledge about the spellings of specific words held in memory as a result of their experiences reading or writing those particular words (i.e., the domain of familiar words referred to earlier).

Knowledge of the Alphabetic System. Knowledge about the alphabetic system and how it works may include a variety of capabilities and types of information: the names of letters, how to group letters into functional units, called graphemes, that symbolize phonemes (smallest units in speech), which graphemes typically symbolize which phonemes, how to segment words into phonemes so that they correspond to graphemes in spellings, how to blend phonemes symbolized by graphemes so that recognizable words result, and how to group letters into larger units comprising spelling patterns and morphographs that symbolize syllabic units including common rime stems, root words, and affixes. Excluded from this are memorized rules that students can state verbatim but have little idea how to apply. My notion of knowledge of the system involves working knowledge that students actually apply to read and spell. I would expect working knowledge to operate more implicitly, "in vivo," than knowledge involving verbalized rules. Learning a rule may be the first step, but if it is not internalized as part of working knowledge, then it remains outside the system. Beginners are usually taught grapheme-phoneme correspondences explicitly when they first learn to read and spell. Many of these associations are learned easily if students already know the names of letters. This is because all letter names but W include relevant sounds, for example /t/ in "tee," /k/ in "kay," /c/ in "aich" symbolized by CH, /ay/ in ''wie'' symbolized by Y as in SKY.4 Henderson (1981), Read (1971, 1975), and Treiman (1993) among others have shown that beginners make use of this knowledge in their attempts to spell words. We have shown that beginners use this knowledge in remembering how to read words as well (Ehri & Wilce, 1985; Scott & Ehri, 1989). Although letter names take care of 25 associations, there are many more to be learned that are not found in names. These may be learned through explicit instruction, or they may be acquired in the course of reading and writing specific words and recognizing regularities that recur across different words. Gough and his colleagues (Gough & Hillinger, 1980; Gough, Juel, & Griffith, 1992) referred to this as knowledge of the cipher. Venezky (1970) has identified many of the grapheme-phoneme regularities that comprise the cipher. Whereas grapheme-phoneme relations are used for reading, phoneme-grapheme relations are used for spelling. According to Cronnell (1978), correspondences for reading are not completely isomorphic with correspondences for spelling. There are about 40 distinctive phonemes in English, but 4 To represent phonemes, symbols are placed between slash marks, for example, /p/. To represent spellings of words, capital letters are used. To represent pronunciations of words, quotation marks are used.

there are about 70 letters or letter combinations to symbolize phonemes. This makes pronouncing spellings easier than writing spellings. Whereas beginners may utilize graphemes and phonemes to read and spell, once students gain more experience with words, they recognize the presence of letter patterns that recur across words. Graphemes and phonemes in common patterns become consolidated into multiletter units that are used to read and spell (Ehri, 1995). Becker, Dixon, and Anderson-Inman (1980) analyzed English words to detect morphographs, defined as irreducible units of meaning in written English, including affixes and root words. The most common morphographs, all suffixes, are: -ED, -ING, -Y, -ATE, -ER, -ION, -LY. A type of spelling pattern found in monosyllabic words consists of common rime stems, for example, -ENT, -IDE, -ICK (Fry, 1994; Treiman, 1985). According to Wylie and Durrell (1970), a list of 37 rimes can be used to generate nearly 500 primary-grade words. Knowing how to read and spell consolidated units such as these eases the task of processing longer multi-syllabic words by reducing the number of separate units to be processed. From this discussion, it should be apparent that my concept of systematic alphabetic knowledge is broad, certainly broader than that proposed by Venezky (1970) or Hanna, Hanna, Hodges, and Rudorf (1966). It includes regularities that others might consider irregularities. For example, when the spelling of a sound is ambiguous in having multiple alternatives (e.g., /k/ spelled C, CK, K, or CH), this is still considered systematic knowledge. If spelling patterns that include silent letters recur in several words, this pattern is systematic, for example, COULD, SHOULD, WOULD, or TALK, CHALK, WALK, BALK. Distinguishing spellings of words in terms of their origins, Anglo-Saxon versus Latin versus Greek, and learning patterns associated with each origin, constitutes systematic knowledge (Henry, 1988, 1990). Of course, I am talking about potential systematic knowledge here. These sources of regularity and others not mentioned are all available for learners to incorporate into their working knowledge of the system. Whether they actually do is another matter. Word-Specific Knowledge. Word-specific knowledge consists of information about the spellings of individual words. This information is derived from reading and spelling experiences and is held in memory. Word-specific knowledge is constructed primarily out of students' knowledge of the general alphabetic system (Ehri, 1980, 1986, 1992). Knowledge of the system functions as a mnemonic tool, enabling students to retain letter-specific information about individual words in memory. In English, specific word learning is necessary because variable spellings are possible. For example, "telephone" might be spelled TELEPHONE, or TELLAFOAN, or TELUFOWN. To the extent that learners see TELEPHONE and process its graphemephoneme relations, they remember this spelling and not the alternatives. Of course, any of these

page_245
next page > Page 245
alternatives is much easier to remember than spellings that lie outside the system, for example, spelling "telephone" as KOMIKEH. This illustrates how knowledge of the system is central for remembering the spellings of specific words. It is important to note that this view of word-specific knowledge differs from other views. Kreiner and Gough (1990) conceptualized word-specific memory as something that operates independently of knowledge of the system. According to their view, word-specific memory may involve visual configurations of words or serial lists of letters but it does not involve rules and regularities. This appears to be quite different from the view that knowledge of the system is the primary stuff used to build word-specific memory. Word-specific memory arises when students read and write words and retain information about the spellings in memory. First, we characterize the representations that are thought to be established in memory for reading words, then we consider representations for writing words. According to our theory and research findings (Ehri, 1980, 1984, 1987, 1991, 1992, 1994; Ehri & Wilce, 1979, 1980, 1982b, 1985, 1987a, 1987b) and a similar theory by Perfetti (1992), the representations formed in memory from experiences reading words are alphabetic and consist of graphemes bonded to phonemes. Elsewhere, I have called this sight-word learning because sight of the word activates its identity in memory (Ehri, 1992). The learning process works as follows: When readers see and pronounce words, their knowledge of the alphabetic system is activated and computes connections between graphemes in the spellings and phonemes detected in the pronunciations of the words. Repetition of this process a few times bonds the spelling of the word to its pronunciation and meaning in memory, forming an amalgam. Figure 13.1 illustrates the connections that might be formed to remember how to read several different words. Capital letters designate spellings, single letters and letters grouped together indicate graphemes, symbols between slashes are phonetic symbols indicating phonemes, and lines linking graphemes to phonemes indicate connections. Notice that some letters are grouped to form digraphs or trigraphs that depict a functional grapheme symbolizing a phoneme.5 Notice that when the vocalic phonemes /l/ and /r/ occur alone in an unstressed syllable, they may be treated as one phoneme, as Treiman (1993) has found. Alternatively, learners may be taught to break the vocalic sound into two phonemes, each connected to a separate graph5 It is important to distinguish letters, which are discrete visual units in print, from graphemes, which are functional units symbolizing phonemes. The only way to distinguish a grapheme in print is to know the phoneme that it symbolizes. Although many graphemes are single letters, there are also several multiletter graphemes.

Fig. 13.1. Connections formed in memory between graphemes and phonemes or between consolidated graphemes and syllabic units to remember how to read specific words.

eme. This approach is more consistent with the principle that every syllable has to have a vowel. This connection forming process is applied to words that are spelled irregularly as well. As illustrated in Fig. 13.1, the majority of the letters in irregular words are consistent with grapheme-phoneme conventions (i.e., all but the letters marked with an asterisk in SIGN, ISLAND, SWORD, and LISTEN). To remember letters that do not symbolize sounds, readers may flag them as silent in memory (Ehri & Wilce, 1982a), or they may create special spelling pronunciations that include the silent letters, for example, remembering LISTEN as "lis-ten." If readers' knowledge of the alphabetic system includes commonly recurring combinations of graphemes and phonemes that have been consolidated, then connections might be formed out of these larger units. In Fig. 13.1, this is illustrated with the words CHEST, and also INTERESTING that can be seen to have four consolidated units formed out of nine grapheme-phoneme units. Notice how many fewer connections must be formed to bond a word in memory when letter patterns symbolizing syllabic units are known by readers. To summarize, connecting spellings to the pronunciations of words in this way secures representations of the spellings in memory to support accurate, rapid word reading. As evident in these examples, the key to establishing high-quality representations of specific words is having general knowledge of the alphabetic system. Let us contrast what must be done to remember how to read specific words with what must be done to remember how to spell them. When students remember how to read a familiar word, they access essentially one "response" from memory, a pronunciation-meaning amalgam. However, when they remember how to spell a familiar word, they must access several "responses" from memory consisting of individual letters written in the proper sequence. Clearly, more information is needed to produce a correct spelling than a correct reading. What is the nature of the representations in memory that enable students to write out all the letters in words correctly? Results of our research indicate that the spelling-pronunciation-meaning amalgams formed in memory to read words are also useful for spelling words. In several studies, we have taught beginners to read specific words under various circumstances and then have asked students to spell the words. In most cases, transfer from reading to spelling was evident. (These studies are discussed more fully later.) However, learning to read words did not enable most participants to spell the words perfectly. Typically, students were able to spell a greater proportion of the letters correctly than entire words correctly: 70%-80% of the letters versus 30%40% of the words. It may be that perfect spelling requires more than the amalgams formed from reading practice, at least among first and second graders.

As mentioned previously, it is easier to read words accurately in English than to spell them. Failure to remember one or two letters dooms a perfect spelling but not necessarily an accurate reading. For example, not knowing the spellings of schwa vowels6 represented by # in EL#PH#NT thwarts spelling but not reading, particularly if the word has been read before. Of course, accurate readings of words without full letter knowledge become problematic for words having similarly spelled neighbors, for example, ST#CK may be STICK, STOCK, STACK, or STUCK. What kinds of letters make spellings especially hard to remember? According to our theory, graphemes that do not follow the conventional system in symbolizing phonemes should be harder to store in representations than graphemes conforming to the system. Also, phonemes having many graphemic options should be a bigger burden on memory than phonemes having only a couple of options. In addition, graphemes that have no correlates in sound, for example, doubled letters and silent letters, should elude memory. Likewise, spelling patterns that recur in few other words and are not built out of conventional graphemes and phonemes should cause problems. Let us examine some words that have parts known to be difficult to spell. The following words include schwa vowels that I have underlined: LETTUCE TERRACE TENNIS
PIGEON VENGEANCE BARGAIN
EXCELLENT CHOCOLATE LIMOUSINE
Notice how variable the letters are. Schwa might be spelled with any vowel letter or pairs of letters, hence making it harder for students to remember the specific letters. Kreiner and Gough (1990) have shown that spellers make more errors on schwa vowels than on unambiguously pronounced vowels. The following words are listed as spelling demons by Fry, Polk, and Fountoukidis (1984): LIEUTENANT SERGEANT RECEIPT AISLE YACHT UNNECESSARY ACCOMMODATE MUSCLE PNEUMONIA VACUUM CONSCIENTIOUS NOTICEABLE What makes these words difficult to spell? According to our theory, students remember best those letters that conform to their knowledge of the alphabetic system, and they have the hardest time remembering letters that fall outside of the system. Inspection of these words reveals that all contain 6 Schwa vowels are the vowel sounds that very often occur in unstressed syllables, for example, the final phoneme in "sofa."

problem letters, including nonconventional graphemes, doubled letters, silent letters, and uncommon spelling patterns, which I have underlined. In addition, many contain schwa vowels. Brown (1988) performed a study in which college students were exposed to misspellings of several words. This was done by having them either read plausible misspellings or intentionally write their own misspellings. Comparison of their performances on spelling tests with the same words before and after their experience with misspellings revealed that their ability to spell the words correctly deteriorated to some extent, more so than among participants who did not experience misspellings. Brown (1988) suggested that the students' representations of some words in memory may include more than one representation. However, inspection of the words he used reveals that most contained problem letters and would qualify as spelling demons. Another interpretation is that the students' initially correct representations of spellings were susceptible to deterioration because some of the letters were not secured well in memory because they fell outside the students' knowledge of the system. As a result, the exercise of computing grapheme-phoneme or phoneme-grapheme connections to either read or write plausible misspellings of the words established the misspellings as compelling competitors, perhaps even replacing correct forms in memory. This explanation receives some support from another finding in Brown's (1988) study. He found that deterioration was much greater when students were exposed to commonly occurring misspellings of the words than when they intentionally created misspellings of the words themselves. It is likely that common misspellings are more plausible and, hence, more seductive than individually produced misspellings. Given that some spellings are fragile, how can they be better secured in memory? Drake and Ehri (1984) investigated one possible way. We showed spellers how to create special spelling pronunciations in which sounds were assigned to letters not pronounced distinctively in the normal spoken forms of words, for example, "chocolate" pronounced "choc" - "o" - "late." We found that spellers were able to remember nondistinctively pronounced letters better if they practiced spellings this way than if they practiced dictionary pronunciations that did not make the letters distinctive in speech. However, this strategy did not improve their memory for doubled letters, not surprisingly because pronouncing does not distinguish the doubled letters in memory. Because of the difficulty remembering all of the letters in many English words, those who are good at it may employ special mnemonic strategies, or they may simply be blessed with good memories for letter details (Simon, 1976; Sloboda, 1980). Possible strategies include letter name rehearsal, for

example, "em-eye-ess-ess-eye-ess-ess-eye-pee-pee-eye" for MISSISSIPPI. Mnemonic rules might be attached to specific words, for example, RECEIVE ("i" before "e" except after "c"). As previously mentioned, special spelling pronunciations might be created. Good spellers might also retain motor routines in memory for writing or typing words they have practiced. How useful such strategies are needs further study. Of course, most spellers do not practice writing all the words that they become able to spell, particularly as their word-specific memory grows very large. According to our theory, if students are able to apply their knowledge of the system to connect and retain in memory all the letters in a specific word they read, they may not need to practice writing the word to spell it accurately. With the appropriate systematic knowledge, they may even be able to read and remember some spelling demons. For example, take the words "noticeable," "vengeance," and "pigeon" that create difficulties for students who process medial E as an extra, inexplicable letter. However, students who recognize that E functions as a marker softening the preceding consonant (C or G)7 should remember E when they learn to read these words and may be able to spell the words correctly without any writing practice. Waters, Bruck, and Malus-Abramowitz (1988) compared students' ability to spell words that exhibited different kinds of spelling regularities. The children were in third through sixth grades. The hardest words to spell were those having letters that fell outside the system, labeled strange words such as AISLE and YACHT. Less difficult were words having letters that could be justified if students knew about affixes and root words, for example, SIGN (related to SIGNAL) and SHORTAGE. Easier than these were words that could be spelled in alternative, equally legitimate ways. For example, DETAIL might also be spelled DETALE. The easiest to spell were completely regular words with few alternative legal spellings. In fact, good spellers made few errors writing these words. These findings support our hypothesis. In sum, the word-specific knowledge retained in memory from reading words contributes to students' ability to spell words. However, the knowledge needed to spell at least some words perfectly may exceed that which is typically stored in memory when words are read, particularly when the words include letters that fall outside the speller's knowledge of the alphabetic system. Spellers may need to invoke special strategies in order to perfect their spelling ability in these cases. Of course, if spellers are taught about additional ways that the system is regular, this should reduce the number of words requiring special strategies to remember. 7 For those who are unfamiliar with this regularity of the writing system, notice how the sound of C and G becomes hard (/k/, /g/) or soft (/s/, /j/) systematically in the following words depending on whether E follows the consonant: manic versus malice; pack versus pace; code versus cede; bag versus badge; sing versus singe; game versus gem (Venezky, 1970).

Three Ways to Read and Spell Words: By Memory, By Invention, By Analogy Having discussed the two types of word knowledge that students hold in memory, we can examine how these sources are used to process words. There are at least three distinct ways to read and spell words: by memory, by invention, and by analogy. Which process is used depends on whether the written forms of the words are familiar or unfamiliar. Familiar words are read or spelled by accessing representations in memory. Unfamiliar words are read or spelled by invention or by analogy. Various strategies offered by third graders to explain how they spelled particular words illustrate the three different approaches (Varnhagan, 1995): (a) "I remembered the word;" (b) "I sounded it out." "Can't put another S so put ES at the end;" and (c) "Just like `old' but with a C." ''I borrowed the GHT from `light.''' By Memory. When information about the written forms of specific words is available in memory, this information is accessed to read or spell the words. We have already discussed the memory processes involved in reading familiar words and in producing correct spellings. By Invention. Children learning to read and spell typically encounter many words that are not familiar and, hence, require attack strategies. One attack strategy for reading words involves decoding the word, that is, applying knowledge about spelling-sound units to assemble a plausible pronunciation that is recognized as a real word. In English, because the spelling system is variable, some flexibility is required in the use of this strategy to derive a recognizable word. The attack strategy for inventing spellings of words involves stretching out their pronunciations, detecting sound units, and applying knowledge of the alphabetic system to generate plausible letter sequences for the sounds. As indicated previously, the likelihood that spellers will generate correct sequences of letters in English is limited because the system is quite variable. The alphabetic knowledge used to invent is similar in the case of reading and spelling. The knowledge sources are listed in Table 13.1. Reading requires blending skill to assemble a unified pronunciation from the separately decoded parts; spelling requires segmentation skill to pull apart and distinguish the phonemes to be spelled with graphemes. Both segmenting and blending are phonological awareness skills that many beginners do not acquire easily without explicit instruction (Liberman & Shankweiler, 1979; Lundberg, Frost, & Peterson, 1988). Beginners rely primarily on grapheme-phoneme or phoneme-grapheme units (GPUs). More advanced readers and spellers may use their knowledge of spelling patterns, consolidated GPUs,

and morphographs in their inventions (Bowey & Hansen, 1994; Laxon, Coltheart, & Keating, 1988; Templeton & Bear, 1993; Treiman, Goswami, & Bruck, 1990; Venezky & Johnson, 1973; Waters et al., 1988). In spelling unfamiliar words, students might also be influenced by partial information they hold in memory about specific words if they remember some but not all of the letters. For example, Simon and Simon (1973) found that the spellings of unfamiliar words generated by fourth graders were more accurate than spellings generated by a computer applying a spelling algorithm. They attribute this to students' partial word-specific knowledge. An example makes this difference apparent: "efficiency" spelled EFITIONSY by the computer versus EFFECIENCY by the students. By Analogy. Another way to read or spell unfamiliar words is by analogy to familiar words already represented in memory. For example, students might encounter the new word "manic." Those viewing MANIC and attempting to read it or those hearing "manic" and attempting to spell it might recognize that it rhymes with a word whose spelling they already know, PANIC. In order to process words by analogy, students must have information about an analogous familiar word stored in memory in enough letter detail to perform a comparison, they must recognize the similarity, and they must access and adapt their knowledge of the familiar word in reading or spelling the unfamiliar word. Of course, in English, this does not guarantee a correct response, particularly in spelling words where a number of phonemically equivalent options exist, for example, BREAD versus RED versus SAID, FINE versus SIGN, RATE versus BAIT versus FREIGHT. Goswami (1986, 1988a, 1988b) has studied the process of analogizing and has found that even beginners can use their knowledge of familiar words to read or spell unfamiliar words. Ehri and Robbins (1992) have found, however, that beginners need some decoding skill to read by analogy. That is, they need sufficient knowledge of the alphabetic system to store full spellings of specific words in memory so that they can detect letter similarities between known and new words. In addition, they need blending skill to put the relevant parts of known and new words together. Campbell (1983, 1985) was able to demonstrate spelling by analogy in adults and older children. Students' spellings of nonwords were influenced by the spellings of real words they heard. For example, if the participants heard "brain," they were more apt to spell /pren/ as PRAIN whereas if they heard crane, they were more apt to spell the nonword as PRANE. Snowling (1994) observed this same effect in children as young as 8 years of age. Success in reading or spelling words by analogy requires remembering related words in sufficient letter detail to perform the transfer. Snowling and

Bowey and Hansen (1994) found that analogizing was more common in older students than in beginners. Levels of Development Various developmental schemes have been proposed to portray how reading and spelling processes change as students acquire word-reading skills and word-spelling skills (Beers & Henderson, 1977; Ehri, 1986, 1991, 1994, 1995; Frith, 1985; Gentry, 1982; Henderson, 1981; Morris & Perney, 1984; Templeton & Bear, 1992). The levels within these schemes have been referred to as stages in some cases and phases in other cases. Although the labels for levels differ somewhat across schemes, the underlying distinctions between less and more mature levels are similar.8 I have labeled these levels with reference to students' knowledge of the alphabetic system because this is the key capability that distinguishes among the levels and underlies development. Each level characterizes the approach that predominates at that level. Development at later levels is viewed as contingent on development at earlier levels except at Levels 1 and 2. Prealphabetic Level. At the earliest level, referred to as prealphabetic, logographic, or precommunicative, children know little about the alphabetic system as it represents speech. In remembering how to read words, they store salient visual features, for example, the two eyes in LOOK (Gough, Juel, & Griffith, 1992). This explains how they read familiar labels and signs in the environment. For example, they read McDonalds by remembering its golden arches rather than any letters in its spelling (Masonheimer, Drum, & Ehri, 1984). At this level, children have difficulty remembering how to read most words because the connections formed in memory are unsystematic or arbitrary. Their only strategy for reading unfamiliar words is guessing. In writing words, children may produce scribbles that superficially resemble cursive writing but lack any letter details (Harste, Woodward, & Burke, 1984). If letters are included, they are not selected because they correspond to any sounds in the words being written. As a result, children cannot read what they have written. Because children's alphabetic reading and writing skills are limited or nonexistent, their achievements here probably have little impact on progress at the next level (Byrne, 1992). 8 My levels do not correspond to those proposed by Frith (1985) in all respects. She regards Levels 1 and 2 as part of her logographic stage. However, results of several studies (Ehri & Wilce, 1985; Rack, Hulme, Snowling, & Wight, 1994) indicate that novice readers and spellers who possess rudimentary alphabetic knowledge learn to read and spell words much differently from prereaders who lack this knowledge and rely on nonalphabetic information.

Partial Alphabetic Level. Once children learn the names or sounds of alphabet letters, they become capable of reading and writing words at the next level of development, referred to as partial alphabetic or semiphonetic. Students' knowledge of the alphabetic system is rudimentary and incomplete at this level. It includes sounds found in the names of letters, including long vowels. However, other vowels and consonants are less well known. To remember how to read words they have read before, they use their knowledge of letter names or sounds to form connections between salient letters seen in words and sounds detected in pronunciations, for example, remembering how to read BEAVER by connecting B and R to the names of these letters heard in the pronunciation, or remembering STOP by connecting initial and final letters and sounds. We have called the use of partial-letter cues phonetic-cue reading (Ehri & Wilce, 1985, 1987a, 1987b; Scott & Ehri, 1989). Because only some of the letters are remembered, words with the same letters may be confused, for example, BEAVER and BROTHER, or STOP and SKIP. The only way that children can read words at this level is by remembering them or by guessing them based on context cues. They are unable to invent pronunciations of unfamiliar words by decoding letters because they lack sufficient knowledge of the graphophonic system, particularly vowels. In attempting to read nonwords, they may guess real words having some of the same letters (e.g., KUG guessed as "king"). Reading and spelling words by analogy is not really possible for students with partial alphabetic knowledge if the analogues are not in view and must be accessed from memory. This is because their memory for specific words lacks sufficient letter detail. Ehri and Robbins (1992) found that novice readers often mistook new words for the familiar words they were analogous to, for example, misreading SAVE as "cave" because the new word SAVE contained the letter cues -AVE used to remember the known word CAVE. Correct spellings of words are very difficult for children to remember at this level because they lack sufficient knowledge of the alphabetic system (Mason, 1980). Most of the letters they see lie outside their knowledge of the system and, hence, appear to be arbitrary. To invent spellings, students detect and spell only some of the sounds in words, mainly the more salient consonants and vowels whose names are heard in the words. In writing the word BEAVER, they might detect consonant letter names or sounds at the boundaries of syllables and write BR or BVR. A letter-name strategy predominates in their writing. This yields some peculiar spellings, such as HKN for "chicken" with H selected because /c/ is heard in its name "aich." Their spellings are partial rather than complete representations of the sounds in words for at least two reasons: They have difficulty detecting and segmenting words into phonemes, and they do not know how to represent all the sounds with letters, particularly vowel

sounds. (For fuller treatment of this level of spelling development, see Henderson, 1981; Read, 1971, 1975; Treiman, 1993.) Full Alphabetic Level. To operate at this level, students need to be able to segment words into constituent phonemes. Also, they need to know conventional grapheme-phoneme units, particularly how vowels are symbolized with letters. With this knowledge, they become able to take full advantage of the alphabetic system for reading and spelling words. They can process spellings of words completely to remember how to read them when letters are consistent with their grapheme-phoneme knowledge. They are able to generate plausible pronunciations of unfamiliar written words by applying decoding skill. This level of development is referred to as full alphabetic, or phonetic, or phonemic. Children operate mainly by applying their knowledge of grapheme-phoneme correspondences in reading, and phonemegrapheme correspondences in spelling. The spellings they invent are more complete than those generated at the semiphonetic level. In fact, in stretching out the sounds in words to spell them, children may find extra sounds not symbolized in conventional spellings, for example, spelling "blouses" as BALAOSIS (Ehri, 1986). At this level, children understand the basic system that underlies and accounts for the presence of many letters in conventional spellings, so they find it easier to remember how to read and write words they have practiced than children at the partial alphabetic level. Also, they have stored words in memory in sufficient letter detail so that reading new words by analogy to familiar words is possible. Consolidated Alphabetic Level. As children practice reading and writing conventional spellings of words, they learn about the structure of larger units in words consisting of letter sequences that recur across several words. These units may involve spellings of syllables, or parts of syllables, or affixes appearing at the beginnings or endings of words, for example, -ING, -ED, -IMP, -ABLE, and -TION. Whereas at the previous level such units were analyzed into smaller graphophonic units, at this level they become consolidated into larger units. In addition, students may internalize other kinds of regularities, for example, letterdoubling rules (e.g., LATER vs. LATTER, WADED vs. WADDED) and other vowel-marking rules (Templeton & Bear, 1992; Venezky, 1970). This developmental level is referred to as consolidated alphabetic, transitional, within-word pattern, or morphemic. Operating with chunks of letters makes it easier for students to decode and invent spellings of longer multisyllabic words. Also, they have an easier time forming connections between letters and sounds to retain the spellings of specific words in memory. This is because their knowledge of the system is more extensive and also because some of this knowledge is redundant.

< previous page
page_256
next page > Page 256
For example, if they know -EST and -OUND as consolidated units symbolizing rimes, they also know the constituent graphemephoneme units. As a result, these units may be double-secured in the representations of specific words. Evidence for Reading-spelling Relationships Our description of developmental levels shows that knowledge of the alphabetic system differs at each level, and these differences are reflected in both the reading and spelling performances of students. Now let us turn to empirical findings to seek further evidence for the claim that reading and spelling are closely related, perhaps almost the same. Correlation Coefficients. How closely associated are word-reading performances and word-spelling performances when measured by word-reading tests and word-spelling tests? Are good readers almost always good spellers and poor readers almost always poor spellers? Are the relationships stronger or weaker at some points of development than at other points? To find out, we can extract correlational findings from various studies in which students of various ages were asked to read and spell words (Ehri & Wilce, 1982a; Greenberg, Ehri, & Perin, in press; Griffith, 1987, 1991; Jorm, 1981; Juel, Griffith, & Gough, 1986). The reading tasks required students to read a list of English words. The spelling production tasks required students to write English words to dictation. The misspelling recognition tasks required students to distinguish correct from incorrect spellings of English words. In some studies, the same words were used across tasks; in other studies, different words were used. From the correlations in Table 13.2, it is apparent that reading and spelling performances were highly related in these studies. To realize the strength of these relations, we can note that most of the correlations are above r = .70, which brings them close to reliability values expected of tests measuring one capability before being corrected for the unreliability of individual measures. Such high correlations indicate that very similar processes are measured in these tasks. This is true among younger as well as older students.9 9 In the study by Griffith (1991), first graders were tested as well. I did not include their correlation because mean performances on the recognition and productions tests were low, with smaller standard deviations than for third graders, suggesting that the tests may have lacked sensitivity at this level.

TABLE 13.2 Correlations Between Reading Words, Producing Correct Spellings of Words, and Recognizing Misspellings of Words at Various Grade Levels Across Different Studies Read Read Spell Studies Spell Recognize Recognize Misspellings Misspellings Juel, Griffith, & Gough (1986). Different words were read, spelled, and recognized. First Graders .84 .74 .76 Second Graders .77 .69 .68 Griffith (1987). Same words were read and spelled. First Graders .83 Third Graders .84 Greenberg, Ehri, & Perin (in press). Different words were read and spelled. Third-Fifth Graders .86 Jorm (1981). Same words were read and spelled.

Seventh Graders .77 College Students .78 Effects of Reading on Spelling. According to our theory, students retain word-specific information in memory when they learn to read words, and this information is available to support spelling performance. Transfer from reading to spelling was evident in a study with second graders (Ehri, 1980). Participants practiced reading one or another phonemically equivalent spelling for each of eight made-up words until they could read them perfectly. Examples of the spellings are: WHEOPLE versus WEEPEL, BISTION versus BISCHUN, GHIRP versus GURP (both members pronounced identically). After a 4-minute delay, students wrote from memory the spellings that they had read. A majority, 69%, were recalled perfectly, indicating that substantial transfer from word reading to word spelling occurred, despite alternative ways to spell the words. Even when students misspelled the words, they restricted their letter choices to those they had seen in the words rather than phonemically equivalent alternatives. For example, all six students who misspelled WHEOPLE began it with WH, not WE-, whereas all four students who misspelled WEEPEL began it with WE-, not WH-. All four students who misspelled BISCHUN included CH, whereas none of the four students who misspelled BISTION included CH. All four students who misspelled GHIRP used I to spell the vowel even though it has no distinctive sound, whereas I was not included

in misspellings of GURP. This provides further evidence that word-specific knowledge retained from reading experiences influenced students' spellings. Results of another study also revealed the impact of reading words on students' memory for their spellings (Ehri & Wilce, 1986). In this study, we used words containing medial flaps that are pronounced more like /d/ in American English but might be spelled with either D or T, for example, HUDDLE, MODIFY, and PEDIGREE versus METEOR, GLITTER, and ATTIC. Second graders were exposed to 12 words, half with flaps spelled D and half with flaps spelled T. Half of the subjects practiced reading the words; the other half heard and practiced saying the words but never saw spellings. Participants practiced the words on one day and then wrote spellings on the next day. We expected that students who read the words would connect graphemes to phonemes and would remember the flap in each word as /d/ or /t/ according to its spelling, whereas students who only listened to the words would spell the flap phonetically as /d/ in most of the words. This was what we found. Participants who read the words spelled 84% of the flaps accurately, whereas controls spelled only 64%. (If students spelled all the flaps with D, their accuracy would be 50%.) Whereas students in the WEEPEL study (Ehri, 1980) spelled words shortly after they read them, students in this study (Ehri & Wilce, 1986) spelled words on a different day. Despite the delay, students' spellings still reflected memory for word-specific information, indicating that memory was long term. We found that the participants' memory for complete spellings of the words in the second study was weak, only 31%, probably because the words contained problem letters such as double consonants (see earlier examples of words). The fact that word-specific effects were evident in spellings shows that if students have partial letter information about specific words in memory, they do not ignore this knowledge and invent a spelling; rather, they access the letters they remember and invent the part they do not remember, as suggested in Table 13.1. In another study (Ehri & Roberts, 1979), we found that the way students learned to read a set of words influenced their memory for the words' spellings. First graders practiced reading 16 words either in written sentence contexts or in isolation on lists. They learned to read the words perfectly. In a spelling test given a day later, students who had read the words in isolation produced significantly more letters correctly than students who had read the words in context: 68% versus 64%. These findings show that variations in reading experiences may impact spelling performance. The focus of transfer effects from reading to spelling in the foregoing studies involved specific words. In other studies, students' knowledge of the alphabetic system was manipulated. In a short-term laboratory study with kindergartners, half of the students were taught to decode CVC (consonant-

page_259
next page > Page 259
vowel-consonant), CCVC, and CVCC words, and half practiced letter-sound relations in isolation (Ehri & Wilce, 1987a). On posttests, the students who received decoding training not only learned to read a set of words more effectively but also spelled them more phonetically and more accurately. Differences between the groups were sizeable. Foorman, Francis, Novy, and Liberman (1991) reported similar findings in a classroom based study. Students who were taught to sound out and blend during their year in first grade exhibited superior spelling ability at the end of the year compared to students who were not taught explicit decoding but did receive other forms of letter-sound training. To summarize, results of these studies confirm that reading impacts spelling in beginners. Findings indicate that readers retain word-specific information in memory that they use to spell the words. The way students practice reading words can influence their ability to spell the words. Instruction that improves students' general knowledge of the alphabetic system through reading benefits their spelling ability as well. Effects of Spelling on Reading. Not only effects of reading on spelling but also effects of spelling on reading have been studied in beginners. Morris and Perney (1984) tested first graders' ability to invent spellings of words before they had received any formal reading instruction. Most children knew all the letters of the alphabet but they were able to spell few words correctly, only 9%. Their spelling inventions were scored to reflect their level of development, with phonetic, conventional letter choices receiving more points than partial nonconventional choices. Results revealed a surprisingly high correlation, r = .68, between spellings invented at the beginning of the school year, and reading achievement scores at the end of the school year. The correlation rose to r = .82 between spellings invented midyear and year-end reading scores. The likely explanation is that invented spellings reflect children's knowledge of the spelling system that determines how quickly they get off the ground and make progress in learning to read. The most important systematic knowledge that children need to have when they begin learning to read and spell is phonemic segmention skill and knowledge of letters. Share, Jorm, Maclean and Matthews (1984) among others have shown that these are the best predictors of reading achievement measured 1 and 2 years later, better even than measures of intelligence. We performed a short-term experiment with beginners to examine the effects of spelling training on word reading (Ehri & Wilce, 1987b). In this study, we manipulated learners' knowledge of the general alphabetic system rather than word-specific knowledge. The students were kindergartners selected because they had limited ability to read words and could not decode. They were at the partial alphabetic level of develoment. Experimental par-

ticipants were taught to segment phonemes and symbolize them with graphemes in CVC, CCVC, and CVCC words and nonwords. Control participants practiced isolated phoneme-grapheme associations. Then the participants were given several trials to learn to read a set of 12 similarly spelled words. Comparison of performances revealed that spelling-trained participants learned to read significantly more words than control participants. Our explanation is that spelling instruction improved the participants' working knowledge of the alphabetic system. With this knowledge, they were able to form more complete grapheme-phoneme connections to remember how to read the words than control participants. In our study, spelling instruction improved their ability to learn to read a set of words with practice, but it did not improve their ability to decode unfamiliar words because it did not include lessons in how to assemble and blend graphemes into phonemes. This same absence of transfer from spelling instruction to decoding was found in a study by Hohn and Ehri (1983). However, Uhry and Shepherd (1993) conducted a spelling instruction study in first-grade classrooms and observed effects on decoding as well as word learning. Participants were first graders with above average IQs. Spelling training lasted much longer, 6.5 months, and included having children not only segment and invent spellings of words but also read the words they had just spelled. Control participants practiced reading the same words but did not segment or spell them. In their classrooms, both groups received reading instruction during the training period. On posttests, spelling-trained participants outperformed controls in nonword decoding as well as word reading, spelling, segmenting, and oral blending. These findings suggest that spelling instruction can facilitate decoding ability as well as specific-word reading if it is structured to improve blending ability. In a classroom-based study by Clarke (1988), two different forms of spelling instruction were examined for their impact on reading over the course of first grade. One form involved having first graders invent spellings of words in their classroom writing assignments. The other involved requiring children to use conventional spellings in their writings. At the end of the year, test performances revealed an effect of spelling treatment on word reading, with children in the invented spelling condition outperforming children in the traditional spelling condition. However, this difference was detected only among children who began first grade with the least knowledge about letters, reading and spelling, not among children who began school with more knowledge. Our explanation is that invented spelling experiences helped novices learn more about the alphabetic system than conventional spelling experiences. Requiring novices to use conventional spellings when they could not comprehend the letter structure of the spellings limited their progress. In contrast, more advanced students understood enough about the system to benefit equally from inventions and conventional forms.

In sum, from the analyses of processes explaining results of these studies, we infer that the reason why spelling helps reading is that spelling instruction helps to cultivate students' knowledge of the alphabetic system which benefits processes used in reading. This conclusion is supported by results from other studies as well (Ball & Blachman, 1991; Bradley and Bryant, 1985; Byrne & Fielding-Barnsley, 1989, 1990; Lundberg, Frost, & Peterson, 1988). In one other study, we examined transfer from spelling to reading that involved specific-word knowledge rather than systematic knowledge. We manipulated second graders' ability to spell specific words and looked for an impact on their reading behavior with the words (Roberts & Ehri, 1983). Although one group learned to spell the words significantly better than the other group (i.e., 88% vs. 83% of the letters correct), the groups did not differ either in their ability to read the words accurately, which was close to perfect, or in their speed to read the words. It may be that deliberate practice rehearsing letters in spellings does not affect reading, or perhaps our groups were too similar in their knowledge of spellings to observe a differential effect on reading. Whether word-specific knowledge transfers from spelling to reading awaits further study. Are Reading and Spelling Independent or Merely Unstable Among Novices? When children first acquire letter knowledge and move into reading and writing, their knowledge of the system is just beginning to form. As discussed earlier, beginners invent forms that are not conventional, and they do this by resorting to various strategies that may draw their attention to one or another aspect of sound that they link to a letter. In stretching out the sounds in a word, they may detect extra vocalic elements that they spell, for example, the O in SOWEMEG (swimming). In carefully analyzing their own speech, they may detect affrication or voicing onset, and this prompts an unconventional spelling, for example, HRK (truck), or SGAK (skate; Read, 1971; Treiman, 1993). Novices are likely to shift in what they attend to and what they ignore as they invent spellings, as there is much that might be noticed and little that they know for sure about how the system works. As a result, it is not surprising to find inconsistency in the features that they represent in their writings. Likewise, in analyzing novices' word reading performances, we have observed substantial variability. When students at the partial alphabetic phase of development practice remembering how to read a set of words, they read them quite inconsistently and mistake one word for another when the two words have letters in common (Ehri & Wilce, 1985, 1987a, 1987b). Bradley and Bryant (1979, 1985) have observed disparities in beginners' word reading and word writing and have suggested that the two processes operate independently during this early period of development. They examined whether beginners' readings and spellings of words were the same or

different on two different occasions. Results showed that children misread some words that they were able to spell correctly on a different day. This was interpreted as evidence for independence. However, Gough et al. (1992) obtained support for a different interpretation. Gough et al. (1992) conducted a similar study in which students performed one or another combination of tasks. The same set of words was either read and reread, spelled and respelled, or read and spelled on two different days. They found a general inconsistency in beginners' performances that was not limited to instances where words were read and spelled; rather, inconsistency prevailed to the same extent across all the combinations of tasks, ranging from 8% to 11%. Importantly, students dealt with the majority of the words consistently (72% to 82%) across the task combinations. These findings challenge Bradley and Bryant's (1979) conclusion that beginners use a different knowledge source to read and spell. Consistency, not inconsistency, predominates even at this beginning level. Recall that in Morris and Perney's (1984) study, spellings invented by novices were highly predictive of later reading. I suggest that even at an early point in development, despite some tendency to be inconsistent, knowledge of the alphabetic system is the major factor imposing consistency on reading and spelling performances. Reading-Spelling Relationships in Disabled Readers and Spellers. So far, we have discussed processes in normally developing readers and spellers. What about disabled readers and spellers? If students are poor in reading, are they also poor in spelling? According to the theory and evidence presented so far, reading and spelling are manifestations of the same underlying knowledge sources. If problems in reading are apparent, we expect to see problems in spelling as well. There are at least two investigations of disabled reading and spelling in which correlation coefficients between reading and spelling performances have been calculated for disabled students separately from normally developing students. Results support expectations in showing that reading and spelling performances are still strongly correlated among disabled students. However, the correlations are not as high as they are with normal readers, indicating that the underlying processes may be less interconnected and interdependent in disabled readers and spellers. In an early study by Guthrie (1973), 19 normal second-grade readers and 19 older disabled readers matched in reading age to the normals were given a four-choice spelling recognition task in which they circled the correct spellings of nonwords they heard. Also they read several short-vowel words and nonwords. Correlations between the spelling task and the other two tasks were:
< previous page

< previous page
page_263
next page > Page 263
Normal readers: r = .84 (words); r = .91 (nonwords) and Disabled readers: r = .68 (words); r = .60 (nonwords). All the correlations were positive and strong, but those among normal readers were substantially higher than those among disabled readers. In a study by Greenberg et al. (in press), 72 normal readers in third to fifth grades were compared to 72 adults matched for reading age. The adults were enrolled in adult literacy programs. Greenberg et al. gave tasks to measure spelling production, word reading (WR), nonword reading (NR), and phoneme deletion (PD). Correlations between spelling production and the other measures were: Normal readers: r = .86 (WR), .62 (NR), .62 (PD) and Disabled readers: r = .57 (WR), .41 (NR), .38 (PD). As in the other study, all the correlations were positive and significantly greater than zero, but normal readers' values were substantially higher than those for disabled readers. The difference was not attributable to differences in the size of the standard deviations in the two groups. One explanation for the lower correlations is that progress is impaired when reading and spelling processes do not become sufficiently integrated as they develop. Various studies confirm that disabled readers possess weaker knowledge of the alphabetic system than normal readers matched for reading age (Greenberg et al., in press; Rack, Snowling, & Olson, 1992). Because of this, knowledge of the alphabetic system may not contribute as strongly to the establishment of word-specific representations in lexical memory among disabled readers as it does among normal readers. Disabled readers may use context to guess words rather than read the words by computing grapheme-phoneme connections (Stanovich, 1980), hence limiting the opportunity for reading to impact spelling. According to our view, the high correlations between reading and spelling performances indicate that the two abilities are so closely related as to look like the same ability, almost. However, in opposition to this is research by Frith (1980) that distinguished a small minority of individuals above age 12 who possessed adequate reading skill but were severely disabled in spelling skill. Such students appear to contradict our view. In a recent replication and extension of Frith's (1980) study, Newman, Fields, and Wright (1993) compared 14-year-old spellingdisabled students to reading/spelling disabled (RSD) students and normal readers. In a retrospective analysis, they found that the spelling-disabled students had exhibited not only spelling difficulties but also reading difficulties during their earlier years. Their history was similar to that of the RSD group. The main difference between the spelling-disabled group (SD) and the other two groups was that the SD group revealed superior verbal IQ scores.

Bruck and Waters (1990) compared spelling-disabled students to RSD and normal-reading students on various tasks and found that spelling-disabled students' oral language skills and reading comprehension were comparable to that of normal students but their word decoding skills were worse and more similar to that of the RSD students. Also, spelling-disabled students read text more slowly than normal students. On sentence completion tasks, performance of spelling disabled students indicated greater reliance on context for reading words than normal readers, revealing the use of compensatory strategies in their text reading. These findings indicate that strong verbal ability enabled the spelling-disabled students to overcome earlier reading difficulties through the use of compensatory processes. Of importance for our purpose is the fact that spelling disability did not emerge in the absence of reading disability. Moreover, when a close look was taken at students' word reading, specific weaknesses were evident, revealing that spelling disabled students are not ''good readers'' at the level of words. Thus, results do not challenge the close relationship between word reading and word spelling. Conclusion: Are Reading and Spelling one and the Same, Almost? I have built a partly theoretical, partly empirical case for the claim that reading words and spelling words are one and the same, almost. I conclude that they are one and the same because they depend on the same knowledge sources in memory: knowledge about the alphabetic system and knowledge about the spellings of specific words. I conclude that reading and spelling are not quite the same because the response performed to read words differs from the response performed to spell words. The act of reading involves one response, that of pronouncing a word. In contrast, the act of spelling involves multiple responses, that of writing several letters in the correct sequence. More information is needed in memory to spell words accurately than to read words. According to my theory, the underlying knowledge sources may fully support both reading and spelling responses for many words that conform to students' knowledge of the system, provided students have read those words enough times in a way that activates connection-forming processes to secure letters in memory. Underlying knowledge sources provide less support for reading and spelling responses when specific words include letters that lie outside the students' knowledge of the system. This is because letters that are not systematic are harder to remember, and even if remembered are weakly secured and hence unstable in the representations. It is important to consider how my theory and evidence relate to the issue of literacy instruction, because there is room for misunderstanding

here. I have shown that reading and spelling processes are very closely related in skilled readers and spellers. However, this should not be construed to mean that we can leave the acquisition of spelling skill to the work of reading instruction and practice. This is because the memory requirements for spelling English words accurately exceed the memory requirements for reading words accurately. Moreover, acquiring knowledge of the alphabetic system is central to development and should fall within the province of spelling instruction. It is unlikely that as students learn to read more and more words, they also necessarily acquire more advanced levels of alphabetic knowledge. In addition, teaching students to read without also teaching them to spell may result in reading and spelling skills that are less closely related, a condition characterizing poor readers and spellers. It is clear that students need explicit spelling instruction as well as explicit reading instruction. According to my theory, the key to effective instruction is integration, that is, fostering close articulation among reading and writing knowledge sources and processes so that their acquisition is mutually facilitative and reciprocal. There is no getting around it by subordinating spelling to the job of computer spell-checkers. Poor spellers do not develop into skilled readers. Spelling instruction must remain an important goal of teachers and schools. References Ball, W., & Blachman, B. (1991).

Chapter 14 Interactions in the Development of Reading and Spelling: Stages, Strategies, and Exchange of Knowledge1 Nick Ellis University of Wales Introduction A number of models of the development of spelling have been progressively refined over the last 15 years (Ehri, 1986; Gentry, 1978, 1982; Henderson & Beers, 1980; Morris, 1983). These share the following commonalities: (a) They are based on analyses of spelling errors when children attempt to spell novel words (invented spellings); (b) they are stage theories, proposing that qualitatively different cognitive processes are involved in children's spelling at different points in development and that there is a characteristic progression from stage to stage; (c) they emphasize that phonological awareness plays a crucial role in children's early spelling but, also, that children eventually acquire orthographic descriptions of words. These models have been developed in parallel with cognitive developmental stage theories of reading acquisition (see Marsh, Friedman, Welch, & Desberg, 1980, 1981) that are also based on error analysis, which also hold that there are very different strategies of information processing used in reading at different stages of its development, and which also emphasize the links between phonological awareness and reading development. Although synchronous, paradoxically these theoretical developments concerning reading and spelling were essentially independent until Ehri (1979, 1984) showed that the improvements 1 Parts of this chapter appeared in G.

in phonological awareness, which are based on the acquisition of alphabetic reading, are themselves a consequence of learning how sound segments in words are spelled conventionally. Hence, Frith (1985) and Ehri (1986) proposed models of literacy development where reading and writing mutually influence and grow from each other. The purpose of this chapter is to briefly summarize the modal aspects of stage theories of spelling development, reading development, and Frith's integrative model, and then to see how well these theories have fared in empirical tests from several longitudinal studies of development that have been prosecuted in recent years. Stages of Spelling Development The idea that children's misspellings reflect a developing sense of phonetic properties in words was pioneered by Read (1971, 1975, 1986) who found evidence that young inventive spellers used a system of grouping sounds together according to shared phonetic features. Thus, they might represent a particular vowel sound in their spelling by substituting a letter whose name shared a salient phonetic feature with the sound. Read's exhaustive studies of invented spellings demonstrated that children use processes of both speech production and perception to group sounds together and that these categorizations may not coincide with the classification system used by adults: We now value spellings for what they can tell us about psycholinguistic processes. Standard spellings are of less interest, not because they represent successful instruction, but because they do not indicate how a child arrived at them. . . Some nonstandard spellings represent a more advanced conception of the task or the language than others. (Read, 1986, p. 47) This idea that spelling errors provide an index of children's metalinguistic understanding of language has allowed subsequent researchers to categorize developmental strategies in spelling. Henderson and Beers (1980) analyzed samples of children's creative writing and assigned each error to a category according to the completeness of phonetic information mapped by the misspelling. On the basis of their work and that of Bissex (1980) and Gentry (1978, 1982), it is now generally agreed that children move through five distinct stages of spelling, namely, precommunicative, semiphonetic, phonetic, transitional, and correct spelling. Precommunicative spellings are characterized by the strategy of randomly selecting letter strings to represent words (e.g., spelling monster as BTRSS, or chirp as 1MMPMPH). Although at this stage children can produce letters in writing, their spellings reflect

a complete lack of letter-sound or letter-name knowledge. Semiphonetic spellings contain a partial mapping of phonetic content. At this stage (a) the speller begins to conceptualize that letters have sounds that are used to represent the sounds in words; (b) the letters used to represent words provide a partial but not total mapping of the phonetic representation of the word being spelled; and (c) a letter name strategy is very much in evidence where possible the speller represents words, sounds, or syllables with letters that match their letter names (e.g., R for are; U for you; LEFT for elephant). At the phonetic stage, (a) phonological segmentation of spoken words is usually evident and, as a result; (b) spellings contain a complete description of the sequence of sounds in pronunciations; (c) all of the surface sound features of the words are represented in the spelling; (d) children systematically show particular spellings for certain details of phonetic form such as tense vowels, lax vowels, preconsonantal nasals, syllabic sonorants, -ed endings, etc.; but (e) letters are assigned strictly on the basis of sound without regard for acceptable letter sequence or other conventions of English orthography (e.g., IFU LEV AT THRD STRET IWEL KOM TO YOR HAWS THE ED for "If you live at Third Street I will come to your house. The End." [Bissex, 1980, p. 13]). In the transitional stage, the child begins to adhere to more basic conventions of English orthography: Vowels appear in every syllable (e.g., EGUL instead of the phonetic EGL for eagle); nasals are represented before consonants (e.g., BANGK instead of the phonetic BAK for bank); both vowels and consonants are employed instead of a letter-name strategy (e.g., EL rather than L for the first syllable of ELEFANT for elephant); common English letter sequences are used in spelling (e.g., YOUNITED for united), especially liberal use of vowel digraphs such as ai, ea, ay, ee; silent e pattern becomes fixed as an alternative for spelling long vowel sounds (e.g. TIPE in place of the phonetic TIP for type), etc. Transitional spellers present the first evidence of a new orthographic strategy, moving from phonological to morphological and orthographic spelling (e.g., EIGHTEE instead of the phonetic ATE for eighty), but they have not fully developed their knowledge of environmental factors such as the graphemic environment of the unit, position in the word, stress, morpheme boundaries, and phonological influences. Acquisition of this knowledge, along with an extended knowledge of word structure (e.g., prefixes, suffixes, contractions, and compound words), an increased accuracy in using silent consonants and in doubling consonants, and simply in knowing when words "just don't look right" (i.e., in having a complete visual orthographic description of them) are elements that allow the mastery of correct spelling. These descriptive categories for this developmental sequence are quite fine grained. They can be more coarsely summarized as a shift from Stage I of early attempts (which may be precommunicative or based on visual copying of whole word or symbol patterns [symbolic or logographic], or

very rudimentary prephonetic attempts representing perhaps just the first sound of a word), through Stage II reflecting varying degrees of mastery of the alphabetic principle, to Stage III of correct orthographic or morphemic spelling (Ehri, 1986; Frith, 1985; Gentry, 1982). Stages of Reading Development Analyses of children's early reading errors (Biemiller, 1970; Torrey, 1979; Weber, 1970) led Marsh, Friedman, Welch, and Desberg (1981) to propose that the first stage of reading could be characterized as one of linguistic substitution when the child uses a strategy of rote association between a simple, unanalyzed visual stimulus and an oral response. "The child typically centres on one aspect of the visual stimulus such as the first letter and associates that with the oral response . . . Their natural strategy is congruent with the `whole word' approach to teaching reading" (pp. 201-202). Frith (1985) called this the logographic stage. If the child does not know the word, she may guess on the basis of contextual cues. Marsh et al. (1980, 1981) suggested that the child next progresses to discrimination net substitution in which "the number of graphemic features a young child can process is limited initially to the first letter, and it is only later that additional features such as word length, final letter, etc. are added. The child at this stage appears to be operating according to a `discrimination net' mechanism in which graphemic cues are processed only to the extent necessary to discriminate one printed word from another." (p. 203). Marsh et al. (1980, 1981) called the next stage that of sequential decoding, Frith (1985) termed it alphabetic, Gough and Hillinger (1980) deciphering, Harris and Coltheart (1986) phonological recoding. In all of these models, this is characterized by the use of individual graphemes and phonemes and their correspondences. "It is an analytic skill involving a systematic approach, namely decoding grapheme by grapheme. Letter order and phonological factors play a crucial role. This strategy enables the reader to pronounce novel and nonsense words" (Frith, p. 308). Both models hold that the final stages of skilled reading take place by the use of orthographic strategies. Marsh et al. (1980, 1981) characterized this as being an extension to the simple decoding strategy (which was based on one-to-one correspondence) where the child now learns more complex rules of orthographic structure the units are letter groups, and higher order conditional rules (such as the magic e rule) are used. Frith (1985), however, suggested that skilled reading involves orthographic strategies where the words are instantly analyzed into orthographic units without phonological conversion: "The orthographic units ideally coincide with morphemes. They are internally represented as abstract letter-by-letter strings. These units

make up a limited set that in loose analogy to a syllabary can be used to create by recombination an almost unlimited number of words.'' (Frith, p. 308). Both the models of Frith and Marsh et al. emphasize analysis of multiple-letter orthographic units, but Frith is implying that practice at the analysis of orthographic sequences will eventually allow nonphonological, wholemorpheme, direct lexical access, with postlexical, phonological retrieval. Interactions in the Development of Reading and Spelling The importance of Frith's (1985) model is that it provides a theoretical framework within which spelling and reading interact to advance the learner toward increased proficiency in each ability. It is a developmental model in which reading and spelling both progress through stages of logographic, then alphabetic and, finally, orthographic strategies. However, her model does more than this in that it suggests reasons for the move from one stage to the next. The crux of her argument is that normal reading and spelling development proceed out of step and that the adoption and use of a strategy in one domain may serve as a pacemaker for development of that strategy in the other. This is illustrated in Fig. 14.1, which shows the points at which the domains are misaligned and the cross-domain influences that are suggested to occur. Claim 1. Frith (1985) suggested that the beginnings of literacy lie in logographic reading when the child has a finite whole-word reading vocabulary and that the development of this means of reading results in its adoption as a strategy for spelling. Thus, Claim 1 is that logographic reading is the pacemaker for the use of a logographic strategy in spelling. Evidence for a logographic stage of reading comes from Seymour and Elder (1986) who showed that 5-year-old beginning readers, who were taught by a predominantly look-and-say method, were able to read aloud words that they had been taught but, nevertheless, possessed no usable procedures for pronouncing new words. However, evidence for logographic reading driving the development of a logographic strategy of spelling is harder to come by. There is little doubt that children are first brought to realize the importance of the written word by seeing them, but several investigators, most notably Goswami and Bryant (1990) seriously questioned the existence of a logographic stage of spelling. Claim 2. At some points of development, reading and spelling are paradoxically out of synchronization. As Goswami and Bryant (1990, p. 148) put it, ''It is still not clear why children are so willing to break up words into

Fig. 14.1. Firth's (1985) model of reading and spelling acquisition (strategies acting as "pacemakers" at each step are italicized). phonemes when they write, and yet are so reluctant to think in terms of phonemes when they read. But there can be little doubt that at first children's reading and spelling are different and separate. The most dramatic demonstration of this separation is the fact that young children often cannot read some words which they know how to spell and also fail to spell some words which they can read." Perhaps the major tenet of Frith's (1985) model, as with that of Ehri (1986), is that children first gain explicit insight into the alphabetic code through practice at spelling and that this causes a shift from a logographic reading strategy to an alphabetic approach. Claim 2 is that alphabetic spelling is the pacemaker for the use of an alphabetic strategy in reading. This can be broken down into two components: Claim 2a is that phonological awareness is much more related to early spelling than it is to early reading; Claim 2b is that this mutually supportive growth of phonological awareness and spelling acts as a pacemaker for the adoption of an alphabetic strategy of reading.

The flesh of the argument of Claim 2 is as follows: It assumes that phonological awareness is important in the development of alphabetic reading (Bradley & Bryant, 1983; Ellis & Large, 1987, 1988), but it is when first attempting to spell rather than to read that the child realizes that a phonological strategy is useful in breaking up print-speech correspondences (Bryant & Bradley, 1980; Frith, 1981; Smith, 1978; Snowling & Perin, 1983). Early spelling practice typically involves dividing spoken words into phonemes and representing these phonemes with letters. In this way, experience in spelling words affords the opportunity for making comparisons between the phonetic information in individual letters and sounds as they are embedded in the spoken word. Spelling practice helps to establish this abstract concept through two very concrete means articulatory and kinesthetic rehearsal and by cross-modal correspondences so that orthographic units guide parsing breaks and provide labels for the sound chunks produced by the novice segmenter. (Indeed, when considering phonology, we cannot ignore our knowledge of orthography once it has been acquired, as is evidenced by fourth graders and above, who think that pitch has four phonemes and rich only three whereas, in both of these words, a phonetic element corresponding to the extra letter t is present in articulation; Ehri & Wilce, 1985). Through repeated practice in spelling, the child may come to appreciate the subtle relationship between a symbol in the written word and its corresponding sound in the context of the spoken word. The discovery of this relationship is the key to alphabetic insight. The crux of the problem is "knowing how to combine the letters into units appropriate for speech" (Liberman & Shankweiler, 1979, p. 141). As children struggle to decompose words into individual phonemic units, they commonly experiment with various articulatory rehearsals of word parts, and they search for distinguishable articulatory units that correspond to letter-sound units. This process of their separating sounds in a word through consciously monitoring their own articulations may serve a dual purpose: It may help the development of phonological awareness, and it may enhance knowledge of the alphabetic principle. As children refine their ability to detect and isolate the sound content of spoken words through repeated practice in spelling, they build a store of knowledge about the relationships among sounds, letters, and pronunciations that can be applied to the task of reading (Chomsky, 1977; Ehri, 1986). Claim 3. Finally, both Frith (1985) and Ehri (1986) supposed that considerable practice at reading by means of an alphabetic strategy encourages sufficient analysis of letter sequences in words to allow the reader to develop internal representations that are well specified in terms of letter-by-letter detail. These orthographic representations acquired through reading are then exact enough to be transferred to spelling and to constitute the knowl-

edge that allows the shift from phonetic through transitional to correct spelling described previously. Thus, Claim 3 is that reading is the pacemaker for the development of orthographic spelling. Frith's (1985) model is also important in that it explains different disorders of developmental literacy in terms of arrest at different stages of development. Because the present purpose is to assess it as an explanation of normal literacy development, these other claims are not addressed further here. If we want to study development, then we must do so directly. Only when the same persons are tested repeatedly over time does it become possible to identify developmental changes and processes of organization within the individual. Cross-sectional studies that compare different groups of people at different points of acquisition must always come in a poor second when small but reliable changes with age are to be detected, when teaching methods and teachers change with time, and when we do not wish to make the artificial assumption that the abilities of a younger cross-section were present in the older cross-section at a previous time (Ellis & Large, 1987). For these reasons, we only weigh the model against the two types of research paradigm that allow some degree of causal interpretation: longitudinal studies and experimental investigations of the effects of training. Tests from Longitudinal Studies of Developmental Phonological Awareness and Alphabetic Reading There have now been a number of longitudinal demonstrations that early phonological awareness (PA) predicts later reading achievement even when prior IQ is controlled (Bradley & Bryant, 1985; Ellis & Large, 1987; Lundberg, Olofsson, & Wall, 1980; Mann, 1984; Stanovich, Cunningham, & Cramer, 1984; see Goswami & Bryant, 1990, and Wagner & Torgesen, 1987, for reviews). It is clear, therefore, that there is a causal developmental sequence whereby alphabetic reading capitalizes on prior phonological abilities. Reciprocal influences are also evident, as metaphonological skills are made relevant and are practiced in alphabetic reading so they themselves are enriched (see Morais, Alegria, & Content, 1987, for review). For example: (a) Portuguese adult illiterates who had never attended school for social reasons scored only 19% correct on tests of phoneme addition and deletion, whereas matched participants who had been taught to read and write in special classes in adulthood scored at over 70% levels. Thus Morais, Cary, Alegria, and Bertelson (1979) concluded that the ability to deal explicitly with the segmental units of speech is not acquired spontaneously in the course of cognitive growth but demands some specific training, which, for most persons, is provided by learning to read and write; (b) Alegria, Pignot,

and Morais (1982) showed that 6-year-old children, trained to read using phonic methods, were much better (58%) at phonemic segmentation than whole-word trained readers (15%); (c) Chinese literates who were taught to read pinyin, an alphabetic script, scored 83% on a test of segmental analysis, whereas nonalphabetic literates who could read logographs only scored 21% (Read, Zhang, Nie, & Ding, 1986)-phonological segmentation is, to some considerable extent, a consequence of alphabetic literacy; (d) In a longitudinal investigation of 40 children learning to read English, Ellis and Large (1988) found that reading ability at 5- and 6-years-old better predicted phoneme segmentation skill one year later than phoneme segmentation predicts later reading; and (e) Perfetti, Beck, Bell, and Hughes (1987) used time-lag, partial correlation analyses of first-grade children's development to demonstrate that phoneme blending predicted later reading ability and this, in turn, predicted later proficiency at phoneme segmentation. They suggested that young children come to possess a basic, primitive awareness of the sounds of language on which alphabetic reading capitalizes. However, learning to read fosters attention to constituent principles of words, and this results in the development of sophisticated segment analysis ability. As this is acquired, so there are further gains in reading itself. Ellis and Cataldo (1990) put a similar case concerning different aspects of phonological awareness and the differential interactions of these with developing reading. Whereas early research into the relationship between reading and phonological awareness did not discriminate between different types of phonemic awareness tasks (Bradley & Bryant, 1985; Lewkowicz, 1980), more recent work suggests that the level of phonemic awareness demanded by the phonological tasks influences the strength of the relationship between reading and phoneme awareness (Backman, 1983). Stanovich, Cunningham, and Cramer (1984) asked children to perform tasks involving the analysis of words for explicit sound content (nonrhyming tasks) and for the perception of overall similarity of sound content (rhyming tasks). They found that the nonrhyming, or analytic, and productive phonological tasks formed a cluster of related skills and that the rhyming tasks did not correlate strongly with the nonrhyming tasks. Snowling and Perin (1983) found that children's ability to perform a segmentation task was not significantly different from their ability in spelling, the close connection between these skills indicating the necessity of explicit PA in spelling. Thus, there seem to be two developmentally different, measurable levels of PA. Children's first awareness of the sound properties of speech is implicit and perceptual. Spontaneous play with rhyming and nonsense words is thought to reflect an overall sensitivity to the sound content of words (Chukovsky, 1968; Clark, 1978; Slobin, 1978). At this point, they are not yet able to consciously reflect on language (Andresen cited in Valtin, 1984; Shankweiler, Liberman, & Savin, 1972). Valtin (1984) described a 3-stage

page_280
next page > Page 280
model for the development of phonological awareness. Initially the child is not aware of the sound value of speech; he or she senses when, but not why, speech acts fail to be communicative. During the next stage, "children become increasingly able to abstract the language from the action and the meaning context and to think about some of the properties of the form of language. Their knowledge of language units is still implicit, however, and related to psycholinguistic units of speech" (Valtin, p. 214). Once the child achieves conscious awareness, he or she demonstrates explicit phonological awareness and can reflect on, produce, and manipulate phonemic units within spoken words. MacLean, Bryant, and Bradley (1987) demonstrated in a longitudinal study that children's early experience of nursery rhymes results in their gaining initial implicit phonological awareness. Bradley and Bryant (1983) and Ellis and Large (1987) reported that very early reading capitalizes on this implicit phonological awareness. Finally, the aforementioned studies, particularly Perfetti et al. (1987), found that experience in alphabetic reading promotes more analytic and explicit phonological awareness at subsyllabic levels. Stanovich (Cunningham & Stanovich, 1990, 1993; Stanovich & West, 1989) presented a body of evidence that appears, interestingly, to contradict the previous conclusions. They used tests of recognition of famous authors and titles to assess the amount to which individuals have been exposed to print and, by inference, the amount of reading that they have done. Although, as is described later, print exposure is highly predictive of orthographic knowledge and vocabulary even when intelligence is controlled, it does not reliably predict phonological processing abilities (e.g., phoneme deletion or transposition) either in children (Cunningham & Stanovich, 1990, 1993) or in adults (Stanovich & West, 1989). These disparate results do not seem attributable to measurement instruments because they use similar sorts of phoneme segmentation tasks to those in the aforementioned studies. An alternative explanation is that the amount of exposure to the written language per se is not the relevant variable. Rather, in normal (as opposed to dyslexic) children, refined explicit phonological awareness at the level of the phoneme is acquired as a result of alphabetic literacy skill that, in turn, is engendered by an introduction to grapheme-phoneme correspondences in spelling. This leads us to the particular question of Claim 2: What is the role of spelling in the coming together of phonological skills and reading? Alphabetic Spelling, Phonological Awareness, and Reading There is now a useful collection of longitudinal studies that address the development of phonological awareness, reading, and spelling. Unfortunately, although they are all informative, they also all have their problems. This

section briefly describes some representative studies and weighs Claim 2 against their evidence. Lundberg et al. (1980) presented the first longitudinal study in which phoneme segmentation and synthesis skills measured during kindergarten in 143 Swedish children were used as predictors of reading and spelling development at the end of Grade 1 and the beginning of Grade 2. There were highly significant correlations between the PA measures and later reading and spelling, demonstrating the extreme importance of PA in literacy acquisition. Unfortunately, the study was marred by too easy a spelling test at Grade 1, resulting in ceiling effects on this variable and lack of discrimination. It is difficult, therefore, to assess whether PA is more involved in early spelling than in reading (Claim 2a) and impossible to look at causal interactions between early spelling and later reading (Claim 2b). Tornéus (1984) investigated the causal relationships between intelligence (IQ), general language development (L), phonological awareness (PA: sound blending and segmentation), reading (R), and spelling (S) in 46 dyslexic and 44 control Swedish children at the end of Grade 1 (IQ1, L1, PA1, R1, S1) and at the beginning (IQ2, R2, S2) and middle of Grade 2 (S3). A number of causal models of interactions in their development were tested using LISREL. There was a very strong causal path from PA1 to spelling (as a latent factor that represented ability over tests S1-S3), but only a slight influence of general linguistic and cognitive development on spelling. The causal model for reading was similar, with the exception that it also included a direct causal path from cognitive development. Moreover, it was clear from Tornéus that the associations between various aspects of PA and spelling at all grades measured (12 correlations ranging from .51 to .73) were considerably stronger than those between PA and reading (8 correlations ranging from .33 to .53), a set of findings consistent with Frith's (1985) Claim 2a that phonological awareness is initially much more involved in spelling than in reading. Unfortunately, there were no models that looked for interactions in effect from reading to spelling, and vice versa, so it is difficult to assess Frith's (1985) Claim 2b about pacemakers from this study (the failure to obtain an R3 measure also limits these possibilities here). Tornéus did provide tests of reciprocal models whereby PA could affect S (or R) and S (R) could, in turn, affect PA. These suggested much more of a causal role in development from PA to reading and spelling than the reverse. However, there are grave problems with these analyses: (a) Solutions to such reciprocal path models are notoriously unstable in causal path analysis; (b) PA was measured at Time 1 only, the composite S variable was measured at Times 1, 2, and 3; and the composite R variable at Times 1 and 2. Therefore, the models that were fitted were looking for causal affects of, for example, spelling midgrade 2 on Grade 1 PA. Because neither time nor development run backwards, it is not surprising that there were low beta-weights on these

paths. Against Tornéus' claims, these models are not fair tests of, for example, Ehri's (1979) claim that phonological awareness arises from acquaintance with orthography gained from practice in spelling. Juel, Griffith, and Gough (1986) assessed a well-motivated range of variables including IQ, listening comprehension, PA (phoneme segmentation and phoneme substitution), exposure to print, nonword reading, spelling recognition and production, reading comprehension, and writing in more than 100 children over the first two grades of their schooling in Texas. Unfortunately, they analyzed the data with a series of cross-sectional rather than time-lag models, and reanalysis is impossible because they do not provide time-lag correlations. Their cross-sectional data do replicate high correlations between PA and both reading and spelling. However, these correlations were of similar magnitude in both grades (Juel et al., 1986), and there is no evidence from their study that explicit PA is more related to Grade 1 spelling than to reading (Claim 2a). The lack of crosslagged correlations precludes a test of Claim 2b. Mommers (1987; Mommers, van Leeuwe, Oud, & Janssens, 1986) described a longitudinal investigation of the first 3 years of development of PA, reading, and spelling in approximately 500 Dutch children. The study is admirable in that (a) word identification, spelling, and reading comprehension were measured in parallel at least at 5 separate points in development, and (b) the investigators analyzed the results with proper longitudinal causal path models. Unfortunately, (a) PA was only measured at the first point, and so reciprocal effects of reading and spelling on PA growth cannot be assessed; (b) as in many of the previous studies, the reading and spelling tests included both regular and irregular words in terms of grapheme-phoneme correspondence, and so we cannot disentangle alphabetic and orthographic strategies; (c) such complex data limit the authors to reporting only the final models resulting from many iterative stages of model refinement. Even so, there is some tentative support for aspects of Frith's (1985) model. In the first place, there were strong effects of initial PA on immediately subsequent single-word reading and spelling abilities even though there was no evidence of a greater contribution on spelling (Claim 2a). In the course of model refinement, the investigators found it necessary to fit a path at the second point of measurement (4 months after the start of formal reading instruction) between spelling ability and word reading (SPo to DSo in their Fig. 5), "a much stronger one than in the reverse direction" (Mommers, p. 136). As this influence of spelling on reading is unique to this early stage of literacy development, this finding is highly supportive of Frith's (1985) suggestion of the influence of spelling on alphabetic reading (Claim 2b). At all subsequent stages, the best fitting causal models had significant, although not large, influences in the reverse direction, that is, from word reading to spelling: "There also exists an influence of decoding skill on spelling. In both

decoding skill and spelling, orthographic representations stored in the lexicon play a part . . . The repeated reading of words can only to some extent improve the quality of the orthographic representations." (Mommers, p. 140). These paths, although small, are supportive of Claim 3. Cataldo and Ellis (1988; Ellis & Cataldo, 1990) charted the development of reading, spelling, and phonological awareness in a group of 28 children during their first 3 years in school. During this time, the children were tested at four intervals in reading and spelling real words and nonsense words, phoneme segmentation, and auditory categorization. The Wechsler Preschool Primary Scale of Intelligence (WPPSI) was included in the set of initial assessments. A test of phoneme segmentation was given as a measure of explicit phonemic awareness, and a test of auditory categorization was taken as a measure of implicit phonological awareness. The majority of the sample had only begun to attend school when the initial assessments were taken at the beginning of the school year when their mean age was 4 years 6 months. The children were retested at the end of their first school year, at the beginning of the second year, and at the beginning of the third school year. Exploratory (LISREL) causal path analyses were used to investigate the contribution of each ability to the subsequent growth of skill in word recognition, spelling, and phonological awareness over three measured phrases of development. Phase One spanned the children's first year in school. Phase Two charted the development from Spring of the first school year to Autumn of the second year. Phase Three looked at development from the beginning of the second year in school to the beginning of the third year. The Phase 1 pathweights from spelling to reading real words (0.31) and nonsense words (0.23) identified spelling as an important contributor to the early formation of reading. This pattern of influence was repeated in the second phase (spelling to reading real words 0.64 and nonsense words 0.60). The pronounced influence of spelling on reading contrasted with the meager contributions of reading to spelling (Phase 1: 0.10 real words, 0. 06 nonsense; Phase 2: 0.14 real, 0.00 nonsense), thus confirming Claim 2b. Implicit PA initially predicted early attempts to read (0.36, 0.41) as well as to spell (0.38, 0.31) but lost its influence on both reading and spelling in the following two phases. In contrast to the diminishing predictive power of implicit PA, explicit PA consistently predicted spelling in all three phases (confirming Claim 2a), this influence increasing with phase. Explicit PA only emerged as a strong predictor of reading in Phase Three. To summarize the Ellis and Cataldo results, the early flow of information between reading and spelling appeared to be asymmetrical: Knowledge gleaned from spelling contributed to reading. Similarly, both implicit and explicit PA affected spelling development, with explicit PA increasing its influence as the contribution of implicit PA diminished. Only later in the developmental sequence did explicit PA begin to contribute directly to reading.

Berninger, Abbott, and Shurtleff (1990) tracked visual language processes (1-second delayed visual recognition memory for a word or for a letter in a word), oral language processes (vocabulary and phoneme segmentation and deletion), reading (word naming and lexical decision), and spelling (written reproduction subsequent to seeing the word) in 42 children during their first grade of school in the United States. Written and oral language abilities at the end of kindergarten predicted reading and spelling at the beginning of first grade. PA skills at this first measurement interval correlated .63 with whole word presentation (WW) reading (lexical decision) but somewhat more so with WW spelling (.74) and WW reading for naming (.77). At the end of first grade the concurrent correlations with PA followed the same patterns with lexical decision reading (.47) lower than spelling (.57) and lower than reading for naming (.74). It seems, therefore, that PA is initially more involved in spelling than in lexical access for reading (although it is involved in reading for naming). This accords with but qualifies Claim 2a. Visual word recognition memory abilities at the end of kindergarten correlated .55 with WW lexical decision reading, .63 with WW spelling, and .63 with WW naming reading, but these dropped dramatically in the concurrent correlations at the end of first grade to .26, .04, and .28 respectively. The fact that there are these visual correlates of both reading and spelling at the start of Grade 1 but not at the end may lend some support to Claim 1 that early reading and spelling are visual, or logographic, in nature and that there is then a shift from this to alphabetic processing. However, this interpretation should be treated with some caution because the visual memory task used by Berninger et al. was not necessarily a hygienic measure of logographic strategy use, and performance on this task could reflect additional influences from alphabetic or orthographic knowledge. Goulandris (1991) reported a small longitudinal study of 27 British children to assess Claim 2b. Verbal intelligence (vocabulary), nonword spelling, reading, and spelling were used to predict reading and spelling 1 year later. Even when verbal intelligence, reading age, and spelling age were partialled out, nonword spelling still predicted reading and spelling 1 year later, clearly demonstrating that a child's ability to generate phonetic spellings is the precursor of the eventual acquisition of alphabetic reading (Claim 2b). Finally, and most recently, there are the studies of Wimmer, Landerl, Linortner, and Hummer (1991). The importance of these studies is that the initial testing was done on children within 1 month of joining school in Salzburg before any reading instruction had taken place. In the first study of 50 children, vowel substitution (their measure of PA) was a significant predictor of end of first-grade spelling (r = .49) and reading (r = .45), and these effects were significant even after IQ, initial letter knowledge, and initial, nonword reading abilities were partialled out. Study 2 investigated 42 children and the degree to which initial PA and rudimentary logographic

(identification of ubiquitous logos such as Coca Cola or Milky Way) and alphabetic (the reading of logos printed in upper case to distort their original distinctive whole-word shape) reading skills predicted later reading of familiar words and nonwords and alphabetic and orthographic spelling. PA later predicted alphabetic spelling (.31) and reading accuracy (.30) but not orthographic spelling (.15). Logographic reading did not predict later reading (.08), but alphabetic reading did more so (.19), suggesting a change of reading strategy over this first year from logographic to alphabetic strategies. Logographic reading did, however, predict later orthographic spelling (.42). Most striking was the finding that PA skill at the end of the year was only moderately predicted by prior PA skill (.31) but was highly correlated with reading accuracy at that time (.53) and even more so with nonword spelling (.66). In other words, over the course of the children's first year of entry into literacy, PA and spelling became strongly enmeshed abilities as a result of a symbiotic developmental relationship. Wimmer et al. summarized their article in the title ''The relationship of phonemic awareness to reading acquisition: More consequence than cause but still important'' and concluded that, in most children, quite limited exposure to reading and spelling instruction is sufficient to induce explicit awareness of phonemic segments of words in a language, at least in languages such as German that have fairly regular grapheme-phoneme correspondences. These findings are compared and brought together with the findings of training studies in the conclusions of this chapter. Orthographic Reading and Orthographic Spelling We have already described Mommers' (1987) finding of causal paths from word-reading skill to spelling at later stages of development. Stanovich (Cunningham & Stanovich, 1990, 1993; Stanovich & Cunningham, 1992) produced a number of group studies that give further confirmation to Claim 3. Stanovich and Cunningham (1992) argued that, when reading, "whatever cognitive processes are engaged over word or word-group units (phonological coding, semantic activation, parsing, induction of new vocabulary items) are being exercised hundreds of times a day. It is surely to be expected that this amount of cognitive muscle-flexing will have some specific effects" (p. 51). They demonstrate, in multiple regression analyses, that adults who read a lot (who have high print exposure, as measured on Author and Magazine Recognition Tests) are better spellers even when nonverbal intelligence is controlled. The same is true for third- and fourth-grade children. Cunningham and Stanovich (1990) found that even after partialling out IQ, memory ability, and phonological processing abilities, print exposure (the amount of reading the child did) accounted for significant variance in orthographic knowledge.

This result is clear confirmation of Claim 3 that the move to an orthographic strategy of spelling was driven by reading at later stages of development. However, Cunningham and Stanovich (1993) also showed that it is true in the case of first-grade children. They demonstrated that 6-7-year-old children's ability to spell phonologically irregular words such as read, talk, mouse, rough, which require consultation of an orthographic lexicon for conventional rather than phonetic spelling, was a separable component of variance in word recognition from phonological awareness. Furthermore, even at these young ages, significant variance in the ability to perform correct orthographic spelling was accounted for by print exposure after phonological processing skill had been partialled out. Thus, there does seem to be clear evidence for Claim 3 that exposure to the letter sequences of words in reading allows the child to develop orthographic representations that can then be used in spelling. However, these results qualify the claim in one important aspect: It seems that, in normal children, this is happening from quite early on in the development of literacy (Grade 1) rather than being solely an aspect of a later third stage of reading and spelling development. Tests from Training Studies Studies that involve training children in PA are fairly consistent in supporting Claim 2a of Frith's (1985) model in which phonological awareness is more involved in early spelling than in early reading-training in PA has its first effect on children's spelling. Bradley and Bryant (1983) taught metaphonological skills to 4- and 5-year-old children who could not read and who were at least two standard deviations below average in sound categorization ability. Some children were trained in categorizing common beginning (hen, hat), middle (hen, pet), and end (hen, man) sounds; others received this training and, with the help of plastic letters, how each common sound was represented by a letter of the alphabet. The training had a positive effect on both reading and spelling measured over the next 4 years, and Bradley and Bryant (1985) concluded that "although others have suggested a link between phonological awareness and reading, our study is the first adequate empirical evidence that the link is causal" (p. 41). However, there is more in their study than this. In the first place, there was much greater benefit from training sound categorization in conjunction with plastic letters that labelled the sounds, confirming the emphases of Ehri (1984) and Frith (1985) that phonological awareness is more readily acquired when it is related to orthography. Second, this training had more effect on later spelling (17 months' gain) than it did on later reading (8.5 months' gain). Tornéus (1984) reported a training intervention whereby 38 first graders were assigned to either phonological awareness training or to a general

language activity control for 8 weeks. They were pre- and posttested on reading, spelling, sound blending, and segmentation. Training of phonological skills was effective and, among the children with the lowest phonological awareness pretest performance, specific phonological training improved spelling performance more than did general language activities. Phonological training did not, however, directly affect reading. Experimental evidence for Claim 2b is provided by Ehri and Wilce (1987a, 1987b) who taught kindergarten children to spell words by attending to constituent letter-sound sequences and, when necessary, to phonetic, phonemic, and articulatory cues. These children learned to read words better than children who were taught isolated letter-sound relationships. Thus, children trained in spelling were superior to matched controls in their ability to use phonetic cues and letter-sound constituents when learning to read. Lundberg, Frost, and Petersen (1988) trained over 200 Danish preschool children who had no reading instruction in phonemic awareness, and they assessed the later effects on reading and spelling in first and second grades. Training had a small effect on rhyming and syllable manipulation abilities and a dramatic effect on phoneme segmentation abilities. These improvements, in turn, had a large facilitative effect on first-grade spelling (p < .001) but only a marginal immediate effect on first-grade reading (p < .10). By the end of Grade 2, however, the effect of training on spelling persisted (p < .001) and, by now, had an additional effect on reading (p < .01). Lie (1991) assessed the effects on later reading and spelling of the training of metaphonological skills in approximately 100 first-grade Norwegian children. Training both in phoneme identification and in phoneme segmentation and blending had a facilitative effect on later Grade 1 and Grade 2 reading and spelling but, again, the initial effect on spelling was somewhat greater than that on reading. At the end of Grade 1, students who had been trained in sequential phoneme segmentation scored significantly higher in spelling than students who had received positional (phoneme isolation) training, a result that stresses that it is important to phonologically analyze a word sequentially in order to spell it. The results of Bradley and Bryant (1983), Tornéus (1984), Lundberg et al. (1988), and Lie (1991) were all consistent with Claim 2a, that phonological awareness is much more involved in early spelling than in early reading. The findings of Ehri and Wilce (1987a) and Lundberg et al. supported pacemaker Claim 2b that the acquisition of phonological awareness in spelling drives the development of alphabetic reading. Longitudinal Studies of Single Cases No chapter on longitudinal tests of developmental models is complete without describing one other essential source of evidence that of detailed longitudinal clinical investigations of single cases. Unfortunately, there is simply

not the space to do justice to this body of research, and, although this small subsection may allow an assertion of formal completeness, it is readily acknowledged that this chapter is far from satisfactory in this respect. Just one study is used to illustrate the power of this approach, particularly with respect to Frith's (1985) claims about developmental arrest. Seymour and Evans' (1988) study was relevant to Claim 1. They analyzed reading and spelling processes in a case (AT) of developmental disability associated with Klinefelter XXY syndrome. Between the ages of 7 and 11, this boy's reading was almost entirely logographic; he had a sight vocabulary of over 500 words that he had been taught, but he was unable to do any sounding and blending, with error rates on nonwords between 95% and 99%. He could spell approximately 170 words, but he only managed 1 out of 200 nonwords correctly. Thus, AT showed an almost complete absence of alphabetic functions, that is, his development was arrested at a logographic stage. Conclusions The longitudinal studies reviewed previously give considerable support for several of the claims of Frith's (1985) model. There is some evidence of a logographic first stage of reading (Berninger et al., 1990; Seymour & Evans, 1988), although no study can be found that provides corroboration of logographic reading acting as a pacemaker for a logographic stage of spelling (Claim 1). Phonological awareness does seem more related, in early development, to spelling than to reading (Tornéus, 1984; Wimmer et al., 1991; cf. Juel et al., 1986; Mommers, 1987), and training in PA first affects the development of spelling rather than reading (Bradley & Bryant, 1983; Lie, 1991; Lundberg et al., 1988; Tornéus, 1984; Claim 2a). The acquisition of PA through spelling engenders development of an alphabetic strategy of reading (Cataldo & Ellis, 1988; Ehri & Wilce, 1987; Ellis & Cataldo, 1990; Goulandris, 1991; Lundberg et al., 1988; Mommers, 1987; Claim 2b; see Ellis & Cataldo, 1990, for the pedagogical implications of this). The acquisition of orthographic knowledge through reading promotes orthographic spelling (Mommers, 1987; Stanovich & Cunningham, 1992; Claim 3). These data also suggest some additions and qualifications. First, they very clearly show that there are different facets of PA, an early implicit awareness of syllables and rhyme, and a later sophisticated explicit ability at segmentation at the level of phonemes. Even very early reading seems to capitalize on this implicit phonological awareness that plays a role in the logographic reading, otherwise characterized as being primarily visual in nature. The aforementioned studies also demonstrate that experience in alphabetic spelling and reading promotes the more analytic and explicit phonological awareness at subsyllabic levels. In normal children, this is acquired very quickly and, although it remains to be determined by just how much, it seems likely
< previous page

page_289
next page > Page 289
that this comes more from alphabetic spelling instruction than from practice in alphabetic reading. Finally, although experience with reading allows the child to abstract knowledge of orthographic sequences that can then be applied in spelling, it seems that this is happening not just with mature readers who are solidly at an orthographic stage of reading but also with first-grade children at the beginnings of literacy. Frith's (1985) model, literally interpreted, is a strong stage model suggesting three very different strategies of reading and spelling at three discrete stages of development. Although this is probably true as a broad characterization, it seems that there are mutual influences between the alphabetic and orthographic aspects of reading and spelling at all stages of development. These qualifications to a stage model of development are taken up by other chapters in this volume. Treiman and Cassar (this volume) showed that there can be some rudimentary influences of orthographic knowledge on spelling right from the beginning: Even early on, children may notice (a) that English words may start but not end with capital letters; (b) that words may end but not start with double consonants; and (c) that letters such as e and s may double but that letters such as a and v rarely do. Rieben and Saada-Robert (this volume) similarly concluded from their word-search and wordcopying data that children are more flexible than a fixed-stage model predicts and that their development is better described in terms of phases of dominance of strategy. A new skill initially builds on whatever relevant abilities are already present, then, as it is used, it may well legitimatize and make more relevant (Istomina, 1975) those prior skills and cause their further development. Stanovich (1986) persuasively argued the case for reciprocal relationships and bootstrapping effects, "In short, many things that facilitate further growth in reading comprehension ability general knowledge, vocabulary, syntactic knowledge are developed by reading itself" (p. 364); "interrelationships between the various subskills of reading and intelligence increase with age, probably due to mutual facilitation" (Stanovich, Cunningham & Feeman, 1984, p. 278, my emphasis). What is true of reading and intelligence also applies to the symbiotic development of spelling, reading, and PA: They interact reciprocally over time. Finer-grained studies are now needed to further determine the contributions from one to the other, the representations of the mutual exchanges (visual, phonological, orthographic), and their particular content at each point in the acquisition of literacy. Ellis (1994) described the type of longitudinal study that remains to be done in order to properly chart the developmental interactions between these representational systems. There is also a role for detailed modelling work in order to understand the formal properties of these connections. How does the nature of the phonological and orthographic representations available to the child determine the kinds of sound-spelling correspondences that are learned and

used at different developmental stages? More specifically, do children begin to spell using high-level (e.g., rime-based) soundspelling correspondences, or lower level (e.g., phoneme-grapheme) correspondences, or are both used as a result of interactions between phonological and orthographic systems at various levels of representation? It is helpful to approach this issue by considering the conflicting levels of representation in the different modalities. In terms of phonological representations, there is considerable evidence that the first sublexical representations to develop are onsets and rimes. Thus, Goswami (1986, 1993), on the basis of a study of analogical transfer by children, argued that rime-based, spelling-sound correspondences are among the first to be used because these are the most relevant phonological units that children initially possess that can be used to link to orthographic patterns. Yet, in terms of orthographic representations, the most salient representational unit in early spelling instruction is the individual letter of the alphabet. When children attempt to make connections between sound patterns and print, they are faced with the impossible task of mapping between incompatible representations. Initially, they have no orthographic rime, letter-cluster units that can be made to correspond with phonological rime units, and they have no phoneme representations that can be mapped on to letter units. To learn to spell, then, the child must not only realize that there is some connection between orthographic and phonological forms but must also develop representations that allow mapping between orthography and phonology at compatible levels. Brown and Ellis (1994b) presented an analysis of the ways in which the different sound-spelling and spelling-sound correspondences could be used, depending on the availability of appropriate representations, and some of the ways in which the availability of units of representation in one domain might encourage the equivalent level of representation in the other. For example, if a child has a phonological representation for the rime /Int/ and is faced with the task of finding some orthographic input pattern that reliably predicts this rime, this may lead to development of a recognition unit for the orthographic pattern int (Goswami, 1993). More detailed models of developmental changes in orthographic and phonological representations are needed to forward our understanding of the developmental reciprocity between representational systems for spelling, reading, and phonology.

Chapter 15 Relations Between Word-search Strategies and Word-copying Strategies in Children Aged 5 to 6 Years Old Laurence Rieben Madelon Saada-Robert University of Geneva Reading and Writing Words: Autonomy or Interdependence? It is possible to distinguish two trends under discussion concerning the relation between the reading and writing of words. A number of researchers focused on the differences between the two areas of processing, sometimes even postulating the existence of two separate lexical memories (Bryant & Badley, 1980; Campbell, 1987; Frith, 1980). Others considered that the reading and writing of words are complementary activities based on the same orthographical and phonological knowledge that is stored in a single system (Ehri, 1980, 1989, 1991a; Gough, Juel, & Griffith, 1992; Perfetti, 1992; Waters, Bruck, & Seidenberg, 1985). As shown, the results of our longitudinal study comparing word-search strategies and word-copying strategies favor the second position. There are, in fact, significant correlations between the reading of words and the writing of words (Gough, Juel, & Griffith, 1992; Zutell, 1992) despite the fact that it is possible to identify participants who exhibit a contrasting pattern, that is, those who achieve high scores in reading tasks but low scores in spelling tasks1 (Bruck & Waters, 1990; Frith, 1980; Waters, Bruck, 1 In fact, the reverse pattern does not seem to exist. Bruck and Waters (1990) pointed out that of 343 third graders and 357 sixth graders, there were no examples of students being good spellers while being bad readers.

& Seidenberg, 1985). Such results have generally been interpreted in terms of models that postulate the existence of two routes for the reading and writing of words. One route is based on the rules of correspondence between sounds and letters (phonological route), which allows participants to read and write pseudowords or uncommon words; the other route is based on the idea of access to a mental lexicon that contains orthographic information about words (lexical route), allowing participants to read or write irregular words (Barron, 1986; Peereman, 1991; Segui, 1991). Thus, Frith studied and compared three groups of 12-year-old children: good readers and writers (++ Group), poor readers and writers (-- Group), and a group consisting of good readers but poor writers (+- Group). Her results lead her to the following two conclusions: (a) The phonological route is active during spelling because a large proportion of the spelling errors encountered in the ++ and +- Groups contain phonological errors; (b) the processes involved in reading and spelling are independent because she assumed that, although good 12-year-old readers employ the phonological route for spelling, they use the direct lexical path for reading. Waters, Bruck, and Seidenberg found these conclusions unconvincing, in particular because there was no experimental verification of the assumption that participants use the direct path for reading. These authors studied three similar but younger (third graders) groups of children and controlled the reading and spelling processes more systematically. They concluded that all the children tended to use the phonological route both in reading and spelling. It should be noted that the dual-route theoretical framework has stimulated much more work in reading than in spelling. However, the collection of papers on spelling processes, edited by Frith (1980), influenced the use of the model for spelling research, and stimulated research focusing on the relationship between reading and spelling. The standard two-process model has been refined and extended since the early 1980s. One example of this development can be found in research demonstrating the importance of analogy strategies for reading and spelling words in both adults (Glushko, 1981) and children (Goswami & Bryant, 1992; Gombert, Bryant, & Warrick, chap. 12, this volume). However, even if the separability of the two routes finds good support in neuropsychological reports (see Zesiger & de Partz, chap. 3, this volume), there is more doubt about the independence of the two paths in normal readers and spellers (Barry, 1994). The traditional interpretation holding that there are two encapsulated processing systems was contested by Seymour (1992). He suggested that there may be a single system managing constraints that are generated by both morphemic (lexical, semantic) and submorphemic (syllabic, phonemic) sources. In effect, postulating that these two sources function interdependently makes it possible to account for the results of experiments that show how participants spell a particular dictated

pseudoword is influenced by the spelling of an orally printed prime word (Campbell, 1983). For example, participants who hear the word sweet before writing the pseudoword /pri:t/ tend to write PREET, whereas those who hear the word treat tend to write PREAT. The orthodox dual-route interpretation may also be incompatible with Perfetti, Zhang, and Berent's (1992) findings that show the pervasiveness of phonological processes in reading with respect to writing systems and to individuals. One further type of result that is frequently cited as evidence of the relative autonomy of reading and spelling: Words that are read correctly are not necessarily written correctly, and vice versa. Such results have been obtained by Bryant and Badley (1980) who observed that when 6-year-old children were asked to read and write the same set of 30 words, an average of 6.3 words could be read but not written, and an average 3.9 words could be written but not read. However, a décalage in favor of spelling over reading is very infrequent; furthermore, Bryant and Badley's results showed that it was no longer present in 7-year-old children. In a recent study using the same experimental paradigm, but with a double pass of the reading and spelling tests, Gough, Juel, and Griffith (1992) confirmed the rarity of this phenomenon and demonstrated that an equivalent percentage of words is either not read or not written in the same way in the two passes. These authors concluded that such results may simply be interpreted as indicative of the instability of performance that is frequently observed in children engaged in a learning process. Although the question of the independence of the reading and writing of words is still largely undecided, there are two reasons for doubting that these two activities function autonomously: First, it is difficult to demonstrate that children systematically use different strategies for reading and spelling; second, even with such a demonstration, it is far from certain that these different strategies operate independently. Are Stage-based Models Good Models for Describing the Acquisition of Reading and Spelling? The literature contains numerous independently proposed stage-based models for the identification (e.g., see Ehri & Wilce, 1985; Frith, 1985; Marsh, Friedman, Welch, & Desberg, 1981) and the writing of words (e.g., see Ehri, 1991b; Ferreiro, 1978; Frith, 1985; Henderson, 1992). These models tend to agree on the distinction between three phases logographic, alphabetic, and orthographic although differences remain in the number of stages identified, the importance attributed to each of them, and the transitional mechanisms that allow participants to move between stages (Ehri, 1991c; Rieben, 1991; Rieben & Saada-Robert, 1991).

However, the independence between the stages of reading and the stages of spelling acquisition has been questioned. Ehri (1980, 1989, 1991a) proposed a process by which the orthographic aspects of words are amalgamated with other aspects already present in lexical memory, in particular with phonological aspects but also with syntactic and semantic aspects, the spelling being used as a visual symbol to aid in the retention of the sounds in memory. Frith (1985) proposed a joint stage-based system for reading and spelling and suggests an out-of-phase model that allows for décalages favoring reading and spelling alternately: Reading reaches the logographic phase before spelling, and spelling overtakes reading at the point when participants accede to the alphabetical phase before reading gains ground once more as they enter the orthographic stage (see Ellis, chap. 14, this volume). The necessity of passing through a logographic stage has also been called into question, in particular with reference to reading (Ehri & Wilce, 1985; Stuart & Coltheart, 1988; Seymour, 1992; Sprenger-Charolles & Casalis, 1995; Wimmer & Hummer, 1990) because some children make use of phonological mediation from the very beginning of learning. Furthermore, if stages provide adequate models for the description of changes in strategy use for the reading and writing of words, the question of their overlap must be studied more systematically (Rieben, 1995a). Traditionally, the idea of stage is interpreted as describing relatively abrupt and generalized qualitative changes. Although this type of qualitative leap has never really been observed, the generally accepted interpretation is that one type of strategy is replaced in a fairly radical manner by another, and we expect to be able to assign a child to a reasonably unambiguous reading/spelling stage (Frith, 1985). However, results exist (Rieben, 1995a; Rieben & Saada-Robert, 1991; Saada-Robert & Rieben, 1993; Seymour & Elder, 1986; Seymour & Evans, 1992) that point to the coexistence of the logographic and alphabetic stages. Such an observation concerning the variability of strategies is not specific to the field of written language. It is also encountered in other fields of learning and, in particular, in the arithmetical domain (Siegler, 1987). From Reading and Writing Words to Searching and Copying Words In most research, the experimental paradigm consists of reading lists of words and spelling from dictation. The participants' strategies are inferred either on the basis of an analysis of the errors they make or on the basis of differences in the processing time required for words or pseudowords, regular or irregular words, common or rare words. However, this type of

paradigm is not suitable for children at the start of the learning process because their lexical knowledge is at once too limited and too idiosyncratic. For this reason, we use a paradigm in which we observe how young children search for and then copy words in a text production situation. In this way, the activity forms part of a wider context that is meaningful for them. Little research has been devoted to the question of word-search studies. A similar paradigm consists of writing a short sentence and then reading it to the child before asking the participant whether a particular word has been written and, if it has, where it appears in the written sentence. This situation has been used by Ferreiro (1978) and Morris (1992) to study children's awareness of the elements that have to be written an interesting result from this research is the finding that 4-year-old children generally think that there is no need to write articles or prepositions and of the segmentation of utterances into lexical units. Ehri and Sweet (1991) reported a study closer to our perspective. In their experiment, a short text was read to the participants over a number of training sessions with the result that they knew its contents practically by heart. The children were then confronted with a variety of postexperimental tests, one of which, a word-recognition task, required them to identify isolated words within the text. Ehri and Sweet showed that the results, like those obtained in more traditional reading tasks, are closely linked to phonological awareness and letter knowledge. A major difference between our situation and the one studied by Ehri and Sweet however, is the role played by memorization of the text. Our experiment made use of long texts (approximately 200 words), collective productions that were read to the students without being memorized. The word-search task required the mobilization of active problem-solving strategies based on cues relating to the properties of the words and texts. Word copying is another area that has not been the object of extensive research. Originally, word copying was viewed as a tool for the study of the graphomotor aspects of writing. More recently, researchers have come to believe that text copying may provide an indication of children's level of acquisition and representation of written language (Fijalkow & Liva, 1988). For example, the longitudinal study conducted by Humblot, Fayol, and Lonchamp (1994) used word copying to study the characteristics of the units processed in the written production of 6- and 7-year-old children. This research shows that copying is far from being a simple, mechanical process, drawing instead on lexical knowledge (the best known words tend to be copied after only a single reference to the written model) and sublexical knowledge (multiple references to the written model implying segmental analysis in the case of unfamiliar words). In children aged 6 and 7, the syllable seems to play an important role in the process of word decomposition.

Our Study Our study of word-search strategies and word-copying strategies approached the theoretical questions discussed previously within a specific perspective that can be summarized in three points. First, because research within a developmental framework that define stages involved in the acquisition of reading/spelling does not pay sufficient attention to individual differences, our perspective is simultaneously developmental and differential. Second, we observe children in functional reading/writing situations (i.e., in communication) rather than in test situations. Third, studies in school allow observations in the students' primary learning environment (Rieben, Meyer, & Perregaux, 1991; Rieben, 1989). Method Our research involved the longitudinal classroom observation of 21 students at four points during the school year in a situation of written utterance, a didactic approach based on the work of Clesse (1977) and Hébrard (1977). In this approach, young prereaders are encouraged to reconstruct and dictate to their teacher a story taken from a children's book previously presented in picture form and then read. This results in the production of a text displayed on three large, wall-mounted pages, the Reference Text (RT). The children are then asked to draw a picture representing one episode of the story and then to write an individual commentary of their drawing, using the RT as a ''dictionary'' in which they can be fairly sure of finding the words they need. During this activity, the word-search strategies and word-copying strategies used by the participants were observed at four points during the school year, approximately every 6 weeks between November and May (T1, T2, T3, T4, amounting to a total of approximately 540 minutes of observation for each student). Participants At the start of the school year (T1), the participants were nonreaders (with the exception of 4 children who could read a few words but could not read and understand a written instruction indicating how to complete a drawing). The group consisted of 11 students in the second year of kindergarten (K2) between 5.0 and 5.11 at the start of the experiment (mean age 5.5) and 10 first graders (G1) between 6.0 and 6.9 (mean age 6.4).2 The children were 2 It should be noted that in French-speaking Switzerland, reading is mostly taught in G1. Our observations also included K1 children, not because we wanted to conduct a systematic comparison between these two school grades but because we wanted to identify the strategies used by younger children and, most importantly, children who were less directly concerned with the acquisition of reading in the classroom situation.

evenly distributed between the different socioeconomic categories (33% high, 33% average, 33% low socioeconomic background). Results Observation of the children's actions and verbal productions allowed us to infer 7 types of word-search strategy and 7 types of word-copying strategy. Separate analyses were conducted and published for the word-search strategies (Rieben & Saada-Robert, 1991) and word-copying strategies (Rieben & Saada-Robert, 1993). Here, the most important results revealed by these separate analyses are summarized before we move on to a study of the relations between the two types of strategy. Word-Search Strategies Seven types of word-search strategy were distinguished, based on: (a) the localization of words in the title that the child has generally memorized (TITLE); (b) the localization of words in the text with the child being aware of the text organization and knowing that the required word is to be found at the beginning, middle, or end of the story or on a particular page (TEXT); (c) visual cues relating to the length or other salient features of the word (VISUAL); (d) grapheme phoneme or syllable correspondence (CORRESPONDENCE); (e) a blind search for and copying of strings of words from the text rereading shows that the children "read" what they wanted to write and not what they have actually written (BLIND); (f) the deliberate search for and copying of a string of words from the text with the child being able to reread what he or she has written (COPY); (g) the direct, correct identification of the required words in the text without sounding (ORTHO). For the 21 subjects and the four periods of observation, 1,044 strategies were counted. These strategies were categorized by two independent judges who agreed on 79% of cases. Table 15.1 presents the percentages for the different types of strategy observed from point T1 though to T4. As expected, ORTHO and COPY strategies increased as the school year developed, whereas use of the BLIND strategy tended to wane. CORRESPONDENCE strategies increased until T3 and then decreased. At no point were the other three strategies (TEXT, TITLE, and VISUAL) particularly frequent, and they did not undergo marked development during the course of the school year. Multidimensional Scaling Analysis (MSA) was performed in order to go beyond the isolated analysis of each strategy individually. The method used was Correspondence Factorial Analysis (CFA) (Benzecri, 1980; for a discussion of the advantage of the method in developmental studies, see de Ribaupierre, & Rieben, 1985; Lautrey, de Ribaupierre, & Rieben, 1986), which permits the joint study of the

strategy and participant spaces. The first extracted factor (which explains 33.5% of the variance) contrasted the very earliest strategies (BLIND) with the most highly developed (ORTHO and COPY) while passing via TITLE, VISUAL, TEXT, and CORRESPONDENCE strategies; the second factor (which explains 23.9% of the variance) distinguished between the strategies that result from a process of automatization or memorization (COPY, ORTHO, TITLE) and those that demand active problemsolving behavior (CORRESPONDENCE, TEXT, VISUAL). Turning to individual participants, we were able to compare their trajectories as defined by their position at T1, T2, T3, and T4 in the four quadrants formed by the space of the first two factors. In general, these trajectories corresponded to the steps described in the stage-based models: transition from the strategies of prereaders (BLIND, TITLE), through the nonautomatized strategies of beginning readers (VISUAL and TEXT logographic phase and reference to context) followed by nonautomatized strategies based on phoneme grapheme correspondence (CORRESPONDENCE alphabetic phase) to, finally, the automatized strategies of quasi-readers (ORTHO, COPY alphabetic/orthographic phase). It is important to note that the phases described earlier cover the period of learning to read in the narrow sense and exclude a period during which this new knowledge is consolidated. This is because, on the one hand, the observed strategies apply to a still limited lexicon bearing on a familiar text and, on the other, because these strategies still result in frequent word-identification errors. Moreover, the children observed in this study differed in the speed with which they made the transition between the various phases and did not make equal use of all the strategies characterizing the individual phases. We hypothesized that the participants may also differ in the shape of their trajectory, with some children omitting the phase in which strategies linked to the alphabetical code are dominant. This hypothesis finds limited support in the results, although it is not possible to assert that these children totally "skipped" the alphabetical phase. When searching for words, most children

next page > Page 303
made frequent use of the alphabetical code even if in class they received no systematic instruction in the rules of phoneme grapheme correspondence. However, the presence of acquisitional trends should not mask the existence of within-subject variability. Although the strategies correspond to different levels of learning, the children did not make exclusive use of a single type of strategy during any given period of observation. Instead, we noted the presence of considerable within-subject variability in strategy use, which is reflected in the high median values for the number of different strategies used during any given period. For the 7 types of strategy, the median number of different strategies used was 4 at T1 and 5 at T2, falling to 4 again at T3 and T4. Thus, children exhibited considerable flexibility during the early part of the school year when the most elementary strategies persisted, despite the fact that more advanced strategies were beginning to appear. This flexibility may result from differences between the words that the children processed. However, it may also be considered as a characteristic of learners during the early phases of learning. Word-Copying Strategies Turning now to the question of word-copying, strategy categorization was based both on qualitative (nature of the sequence of letters transported from the RT to the children's individual sheet of paper3) and quantitative (number of letters in the sequence) criteria. In most cases, we observed children's physical movement from their table to the RT, and it was easy to note how many, and which letters, they collected in one move. However, when a child was sitting nearer to the RT, the reference to the text was established on the basis of head movements. We were able to distinguish between 7 types of strategy embracing the following 14 individual strategies: (a) letter-by-letter transportation (either LETTER-U, letters that were unknown by the child, or LETTER-K, known letters). The distinction was established in view of the results of letter-knowledge tasks used in parallel at T1, T2, T3, and T4; (b) transportation of double letters (DOUBLE, two identical letters e.g., the nn of bonnet; DB+, two identical letters plus another letter e.g., nne of bonnet); (c) transportation of digrams (DIGRAM e.g., an of guirlande); (d) transportation of a syllable (SYLLABLE2, two-letter syllable; SYLLABLE3, syllable of three letters or more); (e) transportation of morphemes (MORPHEME1, single letter e.g., plural s of enfants4; MORPHEME2, two letters e.g., es of petites; MORPHEME3, three letters or more e.g., ait of 3 This is a slightly delayed copy because the children transpose the letters or clusters of letters from the text displayed on the classroom wall to their own sheet of paper. 4 MORPHEME1 strategy was not counted if the remaining part of the word was transported on a letter-by-letter base.

finissait); (f) transportation of a word (WORD2, two-letter word; WORD3 word of three letters or more); (g) transportation of other groups (OTHER2, two letters; OTHER3, three letters or more). For the 21 subjects and four periods of observation, we counted 1,989 instances of strategies (the judges achieved 92% agreement in their assessment of similar data drawn from another sample). Table 15.2 presents the percentages for the 14 categories of strategy at points T1 to T4.5 Two of these categories occurred with a relatively high frequency throughout the year: LETTER-K (which reached its maximum at T2 and then decreased regularly as more complex strategies emerged) and WORD2. LETTER-U strategy was observed at T1 only. All the other strategies occurred less frequently and were not characterized by any marked development during the course of the school year. In order to study the relations between the strategies and the participants' progression, Factorial Correspondence Analysis (FCA) was performed using the same procedure that was applied for the search strategies. The first two factors explained 43.5% and 14.5% of the variance respectively. The first revealed a very clear contrast between transportation of an unknown letter by unknown letter (LETTER-U) and all the other strategies, and this factor might be interpreted as representing the transition from a phase of logographic spelling (absence of code knowledge) to the alphabetical spelling phase. The second distinguished between the strategies as a function of the number of letters transported together in one move, and it may be supposed that this factor accounts for a gradual progression from partial alphabetic cues to more complete orthographic cues. We also expected a more qualitative differentiation that would distinguish between strategies based on submorphemic constraints (LETTER-K and SYLLABLE) and those dependent on morphemic constraints (MORPHEMES and WORDS). Such an interpretation could be derived from the third factor, which explained only 8.2% of the variance.6 Given the age and school grade of the children, it is not very surprising that the marks of the transition from the alphabetic to the orthographic phase are not yet very substantial. Within the two-dimensional space 5 There were two ways of analyzing these strategies, one based on word-specific level and the other based on the language system level. An example taken from our observations helps clarify this distinction. During observation period T3, child 50 transposed the French word garçon in three blocks: gar - ç - on. If analysis was conducted with reference to the word, this copy will be analyzed as SYLLABLE3 LETTER-K DIGRAM. However, if the whole language system provided the reference, then the final block may also be interpreted as WORD2 because, in French, "on" is a simple, common word that may well be known to the child. We consequently performed two sets of analyses and discovered that the results were not fundamentally different. In this chapter, we refer to results obtained using language level as the reference. 6 Another Correspondence Factorial Analysis, grouping together all the strategies without taking account of the number of letters transposed, promotes this type of factor to second place. However, it still accounts for only 18.8% of the variance.

formed by the first two factors, we observed the progression of the children through the quadrants that defined the following phases: (a) transportation of unknown letter by unknown letter; (b) transportation of double letters; (c) transportation of known letter by known letter; (d) transportation of clusters consisting of two, three, or more letters. An unexpected finding was both the relatively high frequency and the precocious emergence of double letter transportation. It was a salient feature of some words that children took into consideration even when they ignored the name or the sound of the double letters. Could this very early sensibility to double letters be related to the observation made by Caramazza and Miceli (1990) showing that geminate letters were extremely resistant to errors in a patient presenting an orthographic buffer deficit? (See Zesiger & de Partz, chap. 3, this volume). As was the case in our analysis of word-search strategies, we noted that there were differences between the participants at T1 and that they progressed through the various phases at different speeds. However, certain qualitative differences were also observed, with phonographic strategies dominant in some children and orthographic strategies dominant in others. As was the case for word-search strategies, the children made use of a wide range of different strategies during each of the periods of observation. With a maximum number of 14 types of strategies, the median number of different strategies used was 5 at T1, 7 at T2, 11 at T3 and 9 at T4. The greatest variability was observed in the middle of the school year (at T3 and, therefore, slightly shifted with reference to the search strategies for which this phenomenon was observed at T2). These results were perfectly compatible with those obtained in connection with word search and again called into question any model that holds that the stages are defined by the exclusive use of a particular type of strategy. The Relations Between Word-Search Strategies and Word-Copying Strategies Two complementary methods were used to study the relations between word search and word copying. First, we compared the results of the separate analyses of the two strategy categories. Second, we presented the results of an FCA consisting of a joint analysis of the two categories of strategy (7 in the case of word search, 14 in the case of word copying). The two types of analysis are not redundant. The first relies on a priori correspondences between two systems of classification established separately; the second tends to provide a posteriori empirical validation of the relations between the whole set of strategies. As far as the separate analyses are concerned, the development of both word-search strategies and word-copying strategies can be described in terms of four operationalized phases represented by the quadrants defined by the first two factors of each FCA. These phases correspond quite closely

to the models described in the literature and may be defined as follows: prereading/spelling (BLIND for word search; LETTERU for word copying), logographic (TITLE-TEXT-VISUAL for word search; DOUBLE for word copying), nonautomatized alphabetical (CORRESPONDENCE/for word search; LETTER-K for word copying), and automatized alphabetical/orthographic (ORTHO-COPY for word search; any clusters of two or more letters for word copying). This progression relates only to an initial phase in the learning of reading and spelling at the end of which the number of words stored in lexical memory is still limited. In other words, identifying certain orthographic strategies with reference to certain words in no way signifies that we are dealing with expert readers/writers. Using the participants' positions in the quadrants defined by the two Factorial Correspondence Analyses mentioned previously, we can construct double entry tables in which the horizontal entries contain the results in connection with word search (1, 2, 3, 4) and the vertical entries present the word copying results (A, B, C, D). Table 15.3 indicates participant frequencies7 in the various cells for each of the periods of observation (T1, T2, T3, T4). A strictly stage-based model predicts that only the diagonally aligned cells will contain observations. The cells located below the diagonal correspond to a situation in which word copying was more advanced than word search, and the cells above the diagonal correspond to a situation in which word search was further advanced. According to Frith's (1985) model, the presence of observations in cells departing from the diagonal in one direction or the other depending on the stage of acquisition is acceptable. Figure 15.1 illustrates the difference between these two models. Whereas Frith's model attempted to describe literacy acquisition occurring over a few years, we are using it here to make predictions on changes appearing over a shorter period of time. For our purposes, the best opportunity to observe the entire range of strategies is covered by a time interval slightly longer than one year and situated, for the average children, between 4-6.5 and 5-6.6 years. The very first use of most sophisticated strategy orthographic in Frith's stage theory (1985) and full alphabetic in Ehri's (1995) more recent phase model appears near the end of this period and allows children to read a few words by sight, even irregular words, if they are familiar and were encountered frequently. In other words, we assume that an "accelerated" progression over the word-reading phases can be observed when limited to words encountered early and recurrently. A strong argument for this view comes from the fact that during the same amount of time, most children progress dramatically in letter knowledge, in phonological awareness, and in their understanding of the alphabetic system. 7 The number of children entered in these tables varies because some children were absent at different times during the school year.

As Table 15.3 shows, only 65% of the participants occupy the diagonal at T1, 50% at T2, 61% at T3, and 63% at T4. What is more, if we follow the development of these same participants through the four tables, we find that of the 19 participants, 21% are always positioned on the diagonal, 37% display more highly developed searching strategies than copying strategies, and 21% display more highly developed copying patterns than searching patterns during at least one period of observation. Finally, in the remaining 21%, copying is sometimes ahead of searching, whereas at other times, searching overtakes copying. The décalages are not systematic in the direction predicted by Frith's (1985) model. Instead, only slightly more than half of the décalages observed (16 out of 29) correspond to this model. These results provide no support for either the strictly stage-based models or for Frith's model. Instead, they conform more closely to a model that postulates an interactive construction and presupposes that, at the margins of the acquisitional trends, there is considerable flexibility in the strategies that are undergoing construction. An alternative method of analyzing these links between searching and copying considers each participant's pattern of search and copying strategies within a single Factorial Correspondence Analysis. In terms of the strategies, this analysis enables us to check whether the correspondences established between behaviors in the contingency tables possess any empirical confirmation. When we turn our attention to the participants, this analysis enables us to develop a description of the global progression of reading/spelling in each child. Figure 15.2 consists of a projection of each strategy (indicated by its code) and each participant at T1, T2, T3, and T4 into the space defined by the first two factors. Each child appears four times in Fig. 15.2 (the G1 participants are indicated by a black square, the K2 participants by a cross), with the exception of two children who were present at only three of the four observation periods. The first (horizontal) factor, which explains 33.5% of the variance, orders the strategies in the sequence in which they are acquired: on the left, where the most elementary strategies are located, we find LETTER-U (for copying) and BLIND (for search), whereas at the opposite end, corresponding to the most developed strategies, we find the transportation of clusters of three or more letters, MORPHEME3, WORD3, SYLLABLE3, and OTHER3, for word copying, and ORTHO and COPY for word search. Between these two poles, we find all the other strategies in the order in which they become dominant during the school year. The second (vertical) factor explains 12% of the variance and can be interpreted in a way similar to that proposed for word search. In effect, it contrasts those strategies that essentially require the mobilization of memorization processes involving both long-term and working memory (WORD3, SYLLABLE3, OTHER3 for copying and ORTHO in the case of word search) with strategies requiring active problem-solving behavior that was

Fig. 15.2. Factorial Correspondence Analysis: location of strategies and subjects in the space defined by Factor 1 (horizontal) and 2 (vertical). more specific to searching than copying (CORRESPONDENCE, TEXT, VISUAL for word search and LETTER-K for word copying). If we now examine the situation of each strategy within the two-dimensional space, we find that the grouping revealed by this analysis corresponds to that established earlier on the basis of the two separate analyses. Again, in comparison with the separate analyses, the order of the search strategies is retained for both factors, whereas the order of a number of very close strategies, that is, strategies with extremely similar coordinates, is inverted. Even though there is no important modification of the order, it is interesting to note that the TITLE strategy, which appears to be one of the strategies involving memorization when viewed in terms of the subset of search strategies, ranks alongside the problem-solving strategies when viewed in terms of the overall set of strategies (closer to VISUAL and TEXT than to BLIND on the second factor). On the basis of the interpretation of the first two factors, the quadrants can be characterized as follows: (a) automatic prereader/prewriter strategies; (b) nonautomatized logographic strategies; (c) nonautomatized alphabetical strategies; (d) partially automatized alphabetic/orthographic strategies of quasi-readers/quasi-writers. When we examine the position of the participants, Factorial Correspondence

Analysis clearly reveals the differences between the K2 and G1 children, most of the latter being found in quadrant IV. This reflects their schooling differences: Children at level G1 have already experienced many activities related to written language, whereas K2 children have been primarily engaged in activities involving spoken language. It is possible to identify each child's progress throughout the year by studying the trajectory defined by their positions within the two-factor space at T1, T2, T3, and T4. By way of example, Fig. 15.2 presents the trajectories of three children. Child 55 (G1) exhibited rapid progress. In this subject, prereader/prewriter strategies (LETTER-U and BLIND) were dominant at T1, with quasi-reader/quasi-writer strategies approaching dominance at T2 before becoming clearly established at T3 and T4. Also interesting is that this child did not pass though a phase in which active problem-solving strategies of the logographic or alphabetical type were dominant. Participant 03 (K2) exhibited a slower acquisition pattern and, more particularly, passed through a phase at which logographic strategies were dominant (T2) and a long period during which alphabetic strategies dominated (T2 and T3) before approaching quadrant IV at T4. Finally, participant 06 (K2) provided an example of a child who did not move from quadrant I throughout the entire school year. Table 15.4 presents the trajectories of the 21 participants.8 Their starting points at T1, their trajectories, and their points of arrival at T4 vary considerably. The participants were classified into three groups depending on their level at T4 the advanced group reaching level IV, the average group reaching 8 The K2 children are coded from 01 to 11, the G1 children from 50 to 59.

level III, and the slow group reaching level I or II. A study of the progression patterns allows us to check, at the level of individual participants, our model postulating a movement away from quadrant I toward quadrant IV. Of the 21 participants, 14 (67%) exhibit ''error-free'' trajectories, without regression. It is significant that of the 7 subjects who exhibit regressions, 6 are found in the slow group. Our hypothesis is that these unstable patterns can be explained equally in terms of the individual characteristics of school children experiencing a greater-or-lesser degree of learning difficulty and in terms of the less reliable observations that result from the fact that these participants have searched for and written fewer words than the others. The Relations Between Strategies and the Reading and Writing of Words In order to confirm the relevance of word-search strategies and word-copying strategies for the study of beginning reading/spelling, Table 15.5 presents the results obtained at T4 by the three groups previously defined in a word reading (12 items) and pseudoword reading task (12 items) taken from Alegria, Content, and Leybaert (1989). It can be seen that the three groups differ in the results achieved in these two tasks, which are the classic tools for the study of reading. In the absence of any similar tests for the evaluation of spelling, an indication of progress was provided by the number of words that the children wrote correctly without having searched for them in the reference text. Table 15.5 shows that the advanced group is clearly distinguished from the other two groups. TABLE 15.5 Results in the Reading Tests for the Fast, Medium and Slow Groups Fast Group Medium Group Slow Group Q IV at T4 Q III at T4 Q I or II at T4 n = 10 n=5 n=6 Pseudoword Reading Median 8 2 0 Min-Max 5-12 0-5 0-0 Word Reading Median 10 2 0 Min-Max 4-12 0-3 0-0 Word Spelling Median 7 1 2 Min-Max 3-14 0-4 0-5 Conclusions Let us return to the question of the tools that enable us to describe the development of reading/spelling in learners at the very beginning of acquisition. Because the entries in their lexicon are both limited and idiosyncratic,

we were dissuaded from studying young children simply on the basis of word-reading and spelling tests. The analysis of the relationships between the strategies and the reading and writing of words and pseudowords has revealed a high degree of concordance, thus validating our method. Regarding the validity of stage-based models, our longitudinal study of word-search strategies and word-copying strategies has revealed a relatively clear acquisitional framework. However, there was considerable variability within each participant at each observation point. These two observations might be seen as contradictory because the greater the variability, the more unlikely it is that the participant is at any particular stage. However, other empirical results have required complexity of numerous sources of variation for description of developmental facts (Lautrey, 1990; Reuchlin, 1978; Rieben, 1995b; Rieben, de Ribaupierre, & Lautrey, 1990; Siegler, 1989, 1995). As far as the learning of the reading and writing of words is concerned, we conclude that the notion of stage cannot accommodate the data. Instead, the developmental trends show what we call phases of dominance. Because our results suggest considerable flexibility of strategies, phases of dominance must allow the simultaneous use of elementary and more advanced strategies. In particular, the coexistence of alphabetical and orthographic strategies seems to lend more support to a theory of amalgamation such as that proposed by Ehri (1980, 1989, 1991a) than to a model that sees a clear distinction between these two stages (Frith, 1985). Furthermore, our data give support to the idea of qualitative changes that are simultaneously discontinuous (to explain the emergence of new strategies) and continuous (to explain the co-occurrence of strategies from different levels). Viewed from this perspective, our data are in agreement with Perfetti's (1991) conceptualization of continuous changes in the quality of the mental lexicon through the mechanism of an increase in the level of precision and redundancy. If we consider the flexibility in strategy use as a psychological phenomenon rather than just background noise, then we must also find an explanation for it. Explanations are possible at a variety of levels. First, at the level of the participant, variability may be a general functional characteristic of all learning. Such variability has an adaptive value and is an indispensable element in any explanation of the emergence of novelty (Piaget, 1975) or an explanation of the way general knowledge interacts with specific knowledge (Siegler, 1989). A second source of variability can be identified in teaching methods whose influence remains to be adequately defined. However, the work of Seymour and Elder (1986) showed that when the teaching method focuses on the visual learning of a word list, logographic strategies are clearly dominant, whereas in a class in which the alphabetical code is systematically taught during the course of the school year, these logographic strategies coexist with alphabetical strategies. The school, and in particular the

page_314
next page > Page 314
class in which our observations were gathered, was characterized by its openness to different pedagogical trends. Despite the fact that the teacher proposed an approach to written language based on oral expression and favored meaning-based language processing, code knowledge, which was not systematically taught, was most clearly present in interactions between teachers and students. Such an environment may contribute significantly to the high level of intrasubject variability that we have identified. A third source of variability resides in the linguistic material, that is, the words. Although effects due to frequency and regularity are well documented, we do not consider that they alone are able to account fully for the flexibility observed at the very beginning of the acquisition of reading and spelling. The reason for this is that the first written words memorized by children are probably not representative of the set of words belonging to a given language in terms of their frequency or regularity. With the exception of words such as daddy, mummy, utility words (the, a, some, etc.) or certain environmental words (Coca Cola, Lego, etc.), the mental lexicons of children aged 4-to-5 consist of subject-specific items, for example, their first names, or surnames, or words encountered in connection with certain books. In fact, what is needed in the field of written language is research equivalent to that which we possess in connection with spoken language (Nelson, 1973), studies that describe, within a longitudinal perspective and for a set of individual cases, what words children attempt to read/write and how they set about doing so. Such research makes it possible to date words in the order in which they enter lexical memory and observe their specific strategic history. Furthermore, such studies help explain within-subject and between-word variability at the beginning of learning. We return finally to the central question of the relations between the reading and writing of words. The concordance obtained between the study of strategies and the reading of words and pseudowords justifies our belief that comparisons of word-search strategies and word-copying strategies constitute a proxy for comparisons of reading and spelling and contribute to the debate on the dependence or independence of the two activities. The groupings of the two sets of strategies resulting from the Factorial Correspondence Analysis exhibited sufficient coherence at each phase to support the idea of a common acquisitional path. However, as for each of the families of strategies analyzed separately, the results show a high degree of variability that sometimes sees reading move ahead of spelling, and vice versa. In this regard, our results do not support the hypothesis that beginning reading and spelling develop in perfect synchrony or the hypothesis of alternating décalages as proposed in Frith's (1985) model. To conclude, we want to emphasize the rich potential of the observations that can be made in classroom situations and the importance of interpreting data relating to the learning of reading or spelling in full knowledge of the

context within which learning takes place. We believe that these advantages far outweigh the drawbacks that result from the fact that the control of variables in such a situation is a somewhat more delicate task. It is clear that this is not a question of opposing experimental studies to field studies but far more a question of viewing the two as complementary parts of the same whole.

Chapter 16 Foundations of Orthographic Development Philip H. K. Seymour University of Dundee, Scotland In this chapter I aim to present the outline of a theory of orthographic development, that is, to provide an account of the progression from preliteracy to skilled reading and spelling (Perfetti, 1992). I make the simplifying assumption that these two processes reading and spelling are both dependent on the development of a single central orthographic resource. Written language systems have been the object of large amounts of linguistic analysis and discussion (Henderson, 1982; Kavanagh & Mattingly, 1972). A distinction has been made between logographic systems, in which symbols represent whole words or concepts, and phonographic systems, in which component sounds are represented. Phonographic writing may take the form of a syllabary or of an alphabet. English is generally held to be an alphabet, although the correspondence between phonemes and graphemes is far from straightforward. Some people take the view that the script is morphophonemic, implying that distinctions of spelling are used to indicate lexical identities, word derivations, and morphological structure. One consequence has been the conclusion that the treatment of English orthography as a simple alphabet is, in principle, inadequate as an approach to the achievement of competence. Almost any word might, legitimately, be written in a number of ways. Because each word is assigned a unique and conventionally agreed spelling, it becomes essential to know the precise arrangement of letters that is appropriate in each case.

Individual Variation The nature of English spelling imposes constraints on the format of theories of the process. For many people, the implication has been that a theory might need to account for two distinct aspects of competence: (a) the establishment of a knowledge of sound letter correspondences (representing the alphabetic basis of the language), and (b) the storage of a large amount of wordspecific and morphological information regarding the actual spellings of simple and complex words (the lexical and morphemic basis). One possibility is a dual-route system in which abstract phoneme grapheme correspondences are separately represented from lexical and morphological aspects (Ellis & Young, 1988; Morton, 1980, 1989; Seymour & Porpodas, 1980). Others have argued that the two aspects of orthographic knowledge might be represented within a single network (Brown & Loosemore, 1994; Seidenberg & McClelland, 1989), or as a letter-sequence generator that operates under various types of (phonological, lexical semantic, and morphological) constraint (Seymour & Evans, 1994a). A key question in the evaluation of the theoretical accounts is whether significant individual variations in spelling difficulties are identifiable. If different types of disability occur, affecting mainly the alphabetic basis in some individuals and the lexical or morphological basis in others, then this will offer strong circumstantial support for models that contain distinct systems or sources of constraint that might be independently vulnerable. This argument was initially set out by reference to cases of neurological damage in adulthood (Ellis, 1993; Shallice, 1988; Zesiger & de Partz, chap. 3, this volume). It was found that some cases presented a phonological pattern in which the ability to write dictated nonwords was lost, although a large vocabulary of real words was preserved (Shallice, 1981), whereas others presented with a pattern of lexical (or surface) dysgraphia in which knowledge of specific word spelling had been lost, although the alphabetic basis of spelling was retained (Hatfield & Patterson, 1983). The position has been less clear-cut with respect to developmental forms of spelling disability. Boder (1973) suggested the existence of dyseidetic and dysphonetic reading-spelling patterns. However, the dominant proposal has been that literacy depends on the formation of an orthographic cipher (Gough & Hillinger, 1980) that encodes the grapheme phoneme correspondences underlying written English. This process is considered to be impaired in cases of dyslexia (Pennington, 1991; Stanovich, 1988). Gough argued that the primary indicator of the possession of the cipher is the ability to read unfamiliar nonwords. This has led to the expectation that dyslexic individuals should appear uniquely deficient in their ability to read or write nonwords (Rack, Snowling, & Olson, 1992). The argument against this single process theory (Mitterer, 1982) rests mainly on studies of variations in the relative degrees of difficulty encoun-

tered in reading or spelling irregular words (an index of lexical competence) and nonwords (an index of alphabetic competence). Ellis (1985) suggested that the distinction might be captured by plotting the locations of cases with respect to two theoretical dimensions: a whole word (lexical) dimension and a phonic (nonlexical) dimension. A few empirical investigations of the actual scatter of cases on these dimensions have now been reported. Manis, Szeszulski, Holt, and Graves (1990) obtained scores for phonological processing (e.g., nonword reading) and orthographic processing (e.g. homophone discrimination) from reading disabled samples and reading-level-matched controls. Performance of the cases of disability was expressed as a deviation from the control mean on these two dimensions. The results show evidence of a scatter, with cases differing in the relative degree of impairment on the two dimensions. Castles and Coltheart (1993) contrasted reading performance on lists of irregular words and nonwords in samples of reading disabled children and age-matched controls. A regression analysis indicated that some individuals performed at a normal level with nonwords but were impaired in irregular word reading, whereas others showed the opposite pattern. This was taken as evidence for the existence of developmental forms of surface dyslexia (impaired acquisition of lexical reading) and of phonological dyslexia (impaired acquisition of alphabetic reading). Seymour and Evans (1994a) plotted the scatter of cases of disability on dimensions defined by error scores for nonword spelling and lower frequency word spelling. Some individuals showed a positive lexicality effect (nonword spelling worse than word spelling), whereas others showed a negative lexicality effect (low frequency word spelling worse than nonword spelling). This contrast was reflected in reading, partly in the magnitude of the discrepancy between error rates for words and nonwords, but also in more detailed features of processing, such as reaction time profiles and word length effects (Seymour & Evans, 1993). Two contrasting cases, DK and RC, who exemplified phonological and lexical dysgraphia, have now been followed over a period of years (Seymour & Bunce, 1994) during which time the underlying patterns have persisted. These studies strongly favor the view that developmental orthographic impairments may selectively affect either the lexical or the alphabetic aspects of written language. It follows that theoretical accounts should, ideally, include mechanisms that allow for differential impairments and contrasting patterns of disability. The Role of Phonological Awareness A common theme in theories of literacy acquisition has been an emphasis on the contribution of phonological abilities. Most commentators agree that acquisition of an alphabetic writing system is contingent on the capacity to

develop an awareness of speech segments, especially at the phonemic level (Bertelson, 1987; Liberman, Shankweiler, Liberman, Fowler, & Fischer, 1977; Morais, 1991). It is also broadly agreed that phonemic awareness does not normally arise as a spontaneous product of maturation (Morais, Cary, Alegria, & Bertelson, 1979) but as a response to demands imposed by instruction in the alphabetic basis of literacy (Morais, Alegria, & Content, 1987; Perfetti, Beck, Bell, & Hughes, 1987). This interactive link between phonemic awareness and literacy is supported by correlational studies and some training studies (Lundberg, Frost, & Petersen, 1988). One important area of dispute relates to the distinction between phonological skills that are available prior to literacy and those that only emerge during acquisition. The contribution of the work of Bryant and his colleagues has been to demonstrate that some phonological skills, especially in the area of rhyming and alliteration, may be available to preliterate children and may also predict later reading achievement (Bradley & Bryant, 1983; Bryant, MacLean, Bradley, & Crossland, 1990). These early skills have typically been measured using tasks such as rhyme generation or selection of the odd-man-out in a list of spoken words. Bryant has raised the question of the relationship between early (preliterate) phonological skills and later development of alphabetic literacy and phonemic awareness. One possibility is that a pathway can be traced that relates early speech games such as chanting nursery rhymes to rhyming ability and, thence, to a capacity to develop phonemic awareness during the acquisition of literacy. Using stepwise, multiple regression techniques, Bryant has presented evidence to support this hypothesis. However, in other analyses, he has secured evidence that indicates that there may be a contribution from rhyming ability to literacy over and above the connection between rhyming and phonemic awareness. This conclusion led Goswami and Bryant (1990) to propose an alternative theory of literacy acquisition in which the role of rhyme structures is emphasized. The main assumptions of this theory are: (a) Children arrive at the task of acquiring literacy with rhyming skills in place, (b) rhyme-based phonology provides a basis for categorizing words in terms of similarity of sound and orthography, and (c) this basis is used to build a lexicon of words by a process of detection of analogies between known words and unfamiliar words. It appears, therefore, that there are two accounts of the way in which phonological processes have an impact on literacy. These can be clarified by referring to the hierarchical model of the internal structure of the syllable (see Fig. 16.1) that has been developed by Treiman (1992) and others. It is supposed that the syllable subdivides naturally into an onset (the initial consonant group) and a rime (the vowel and any following consonants). This can be referred to as a two-dimensional (2D) level because it is based on the supposition that English syllables can be constructed by combining ele-

Subdivision of the rime into a vowel and terminal consonant group defines a further level that can be thought of as three-dimensional (3D) because it is implied that syllables are constructed by combining elements from lists of initial consonant groups (ICs), vowels (Vs), and terminal consonants (TCs). A fourth level can be identified at which the IC and TC structures are broken into sequences of phonemes. The debate regarding the manner in which phonological awareness influences literacy concerns the level within this hierarchy at which the critical units are represented. On the one hand, there is the view that phonological development naturally progresses down the hierarchy, from syllables, through onset and rime structures, and eventually to phonemes (Treiman, 1987). It is this view that motivates Goswami and Bryant's (1990) contention that it is the high-level structures that are important. Against this, there is the view that it is the lowest phonemic level that is essential because, in an alphabetic language, it is the phonemes that stand in correspondence with the letters of the alphabet. Dual-foundation Model of Orthographic Development In the remainder of the chapter, I discuss a theory of orthographic development that I have previously referred to as a dualfoundation model (Seymour, 1990, 1993). The theory is intended to provide an account of the development of an orthographic system (or cipher, in Gough's terms) that takes note of the points that have already been raised, notably: (a) that English orthography encodes information at lexical and morphemic levels as well as at an alphabetic level, (b) that spelling disabilities may take different forms that relate to the lexical versus nonlexical contrast, and (c) that linguistic awareness may affect literacy at an onset rime level as well as at a phonemic level.

A diagrammatic representation of the model is given in Fig. 16.2. The model contains five distinct components, each of which may be thought of as referring to a processor or module. Two of these, the Logographic Process and the Alphabetic Process, are held to perform a foundation role (i.e., to provide a basis for more advanced developments). This does not mean that their existence is restricted to the early stages. In fact, they persist over time and make continuing contributions to development. The third component, Linguistic Awareness, performs an enabling function because interactions with this component are necessary for development in the other systems. Finally, there are two central structures the Orthographic Framework and the Morphographic Framework that perform a representational function because it is in these systems that an individual's abstract knowledge of the orthography is stored. The formation of the central systems depends on the availability of the foundations and on the possibility of developing appropriate forms or levels of linguistic awareness. Logographic Process The term logographic is used here as a reference to a process that is concerned with the direct recognition and storage of words. The Shorter Oxford Dictionary defines a logography as ''a method of printing with entire words'' and logographic as "consisting of characters or signs, each of which represents an entire word." The assumption is that English words, although composed of letters, may be treated as units in this sense. This does not

imply adherence to the connotations that have (erroneously in my view) been attached to the word logographic in recent debates. Hence, it is not equated with recognition of logos or reliance on visual cues even though these primitive processes may represent the early stages in the development of the process (Seymour & Elder, 1986). This account of logographic literacy includes both the visual cue and the phonetic cue stages in Ehri's (1992) theory (i.e. encompasses what Ehri called the alphabetic stage of sight word reading). The process is a complex one that advances in precision and completeness as development proceeds (Seymour & Elder, 1986; Stuart & Coltheart, 1988). The main point is that word representations are encoded, normally consisting of partial or complete letter identity information. This process is considered vital for orthographic development because it is the way in which the exemplars, from which the orthographic information is to be extracted, are internalized. As new words are encountered, they enter the logographic process in a more-orless complete form and provide the data for an ongoing process of orthographic (and morphographic) construction (indicated by the arrows in Fig. 16.2). It is hypothesized that, in some individuals, the logographic process may be inherently underresourced. This will limit the scope for processing words and letter groups holistically and for storing the outcomes of such processes. A logographic impairment of this kind will be evident as a difficulty in acquiring a sight vocabulary. The long-term consequence will be a distortion in the development of the orthographic system that is manifest as a surface dyslexic pattern of disabled reading and spelling. The logographic process is not thought to require phonological organization below the level of segmentation of spoken language into lexical units. This is suggested by observations that an early focus on whole word methods does not support the development of speech segmentation. For this reason, no interactive relationships with Linguistic Awareness are indicated in Fig. 16.2. However, the process might well develop an internal sensitivity to graphotactic constraints. If this occurred, we could expect to find that logographic readers were able to discriminate between orthographically legal and illegal letter arrays and to produce orthographically well-formed (though phonologically inappropriate) letter sequences when attempting to write unfamiliar items. Alphabetic Process The alphabetic process is founded on a knowledge of the letters and their equivalent sounds. As such, the term alphabetic corresponds to the dictionary definition of "any set of characters representing the simple sounds in a language." Acquiring the letters can be viewed as a second form of logographic learning. The letters are arbitrary signs that have to be linked to their names. There is some disagreement as to whether these names should

be the alphabet names "ay-bee-see-dee," and so on, or whether it is preferable to teach children a set of sound names "ah, buh, kuh, duh." The point at issue here is which system may be more helpful in allowing children to infer the phonemic equivalent of each letter. The target phonemes in both systems are often embedded in the names, although in a more systematic and complete way in the case of the sound names. The acquisition of the letter identities presents a problem in only a minority of cases of reading disability. The difficulty seems to arise in applying this knowledge in a systematic way by reading sequentially from left to right, deriving a sequence of sounds, stripping away the schwa vowels, and organizing the whole into a spoken response. It is this operation of grapheme phoneme translation that is the essence of the alphabetic process. In the model, the alphabetic process is represented as standing in an interactive relationship with the phonological component of linguistic awareness. The essential proposal is that acquisition of the alphabetic process entails the isolation of phonemic structures in speech. This is consistent with the numerous demonstrations that the emergence of an ability to manipulate phonemes coincides with the introduction of alphabetic teaching (Alegria, Pignot, & Morais, 1982). In the early stages, alphabetic processing is likely to be accompanied by overt sounding and appears to be functionally distinct from the logographic process (Seymour & Evans, 1992). Thus, a familiar word can be recognized directly by the logographic process, whereas an unfamiliar word is submitted to a sequential process of letter sounding and assembly of a response. The model allows that the alphabetic process may survive into later development as a procedure that can be used to translate unfamiliar forms on a letter-by-letter basis. Many people view a difficulty in establishing the alphabetic process as the key characteristic of reading or spelling difficulty. This could be due to limitations on the decoding of unfamiliar words or because alphabetic processing is needed in order to establish attention to the identities and positions of all of the letters contained in a word (Frith, 1985). Others argue that the grapheme phoneme links, once established, become part of the word recognition process, resulting in lexical access pathways that are precise, phonemically based, systematic, and overdetermined (Ehri, 1992; Perfetti, 1992; Stuart & Coltheart, 1988). The mechanism proposed in the present account is slightly different. It is agreed that letter identities may be incorporated into the logographic process and that this leads to the internalization of increasingly detailed and specific representations. However, the major contribution of the alphabetic foundation is held to be in the formation of the orthographic framework, especially the implementation of a core structure that is the basis for subsequent developments. The proposed mechanism is described more

fully later in this chapter when the orthographic and morphographic systems are discussed. Linguistic Awareness Literacy development is thought to require the establishment of linguistic segments via an interactive process of matching orthographic segments against speech segments. The nature of the demand to develop new forms of segmentation varies as a function of developmental level. One possibility is that a distinction is needed between a natural course of (implicit) phonological development, which proceeds from larger units (words and syllables) through intermediate units (onsets and rimes) to small units (phonemes), and a demanded sequence of literacy-related explicit awareness that develops in the opposite direction, from small units toward larger ones (Seymour & Evans, 1994b). The reason for this conflict is to be found in the priority that is accorded to the alphabetic foundation. As has been discussed, the formation of the alphabetic process involves an interaction with Linguistic Awareness that has as its primary outcome the emergence of an awareness of phonemes. Thus, although there might be a natural proclivity for a progressive development from syllables to onsets and rimes, this tendency is overridden by the demands of acquisition of the alphabetic principle. This does not mean that higher order structures are not important in literacy development, only that their importance arises later rather than earlier. The reason for this is that the higher order structures do not become relevant until the stage when the orthographic framework is being formed. These points can be clarified by referring back to the hierarchical representation of the syllable shown in Fig. 16.1. What is suggested is that the natural development of implicit phonological awareness normally proceeds down the hierarchy from whole syllables through onsets and rimes toward the phonemic level. The acquisition of alphabetic literacy, by contrast, imposes a demand for the development of explicit phonological awareness of speech segments that starts at the phonemic level and proceeds upwards through the hierarchy to the three-dimensional and, eventually, to the two-dimensional levels. Evidence bearing on these arguments has recently been presented by Seymour and Evans (1994b) and by Duncan, Seymour, and Hill (in press). In the first study, Scottish primary school children were asked to perform a segmentation task under three different instructions, involving division of a spoken word into two parts, three parts, or as many parts as possible. These instructions can be equated with the 2D, 3D, and phonemic levels of the syllabic hierarchy (Fig. 16.1). The items were monosyllables (words or nonwords), some of which contained consonant clusters. The results suggest

that preliterate children were unable to segment at any of the three levels. As literacy was acquired during the first 2 primary school years, there was a gain in segmentation ability that favored small unit (phonemic) division over large unit (onset-rime) division. In the second study, children in the first primary year performed a common unit task. A pair of spoken words was presented and the child was asked to report back the shared segment. This could be a large segment such as the rime, or a smaller segment including a vowel, consonant, or consonant cluster. The children were more adept at reporting back small shared segments than large ones. A further experiment tested their ability to pick out the letters in a word that corresponded to a spoken segment. Children were better able to identify small orthographic units than large ones. These experiments indicate that initial teaching that includes an alphabetic component tends to direct developing phonological awareness toward the phonemic (small unit) level. In the model, a second form of linguistic awareness is hypothesized, referring to the morphological structure of words. This is needed for the most advanced level of development at which a capacity to spell complex words composed of combinations of syllables, prefixes and suffixes, is required (Seymour & Evans, 1994a). Orthographic Framework The heart of the theory of literacy acquisition is the formation of the orthographic framework. This is viewed as a structure that encodes a generalized knowledge of the correspondence system together with word-specific features, as has been suggested by Seidenberg and McClelland (1989). For the purposes of the present discussion, I make the simplifying assumption that this information refers to English monosyllables and disyllables. It is assumed that the Orthographic Framework develops progressively, dealing at first with quite simple structures but undergoing a gradual elaboration that incorporates multiletter structures, including consonant groups and vowel spellings. During the time in which the framework is being formed, the logographic system contains representations of a wide range of words, only some of which offer appropriate examples for the orthographic representation that is currently being built up. Thus, the vocabulary available within the logographic system is typically in advance of the region of the orthography represented in the orthographic system, at least in the early stages of development. This relationship between the logographic store and the orthographic framework is somewhat reminiscent of Perfetti's (1992) distinction between a functional and an autonomous lexicon. However, in the present account, the logographic entries may be relatively complete and well specified, and the distinction between the systems is that one holds word-specific representations, whereas the other is engaged in the construc-

tion of an abstract description of the orthography. Hence, a process akin to Karmiloff-Smith's (1986) notion of representational redescription may be a closer parallel (Seymour, 1993). In the model, it is suggested that the development of the Orthographic Framework proceeds through a number of steps or stages. These are referred to as the core, the intermediate, and the advanced stages. The actual progression is likely to be more complex than this, involving a larger number of levels and some intervening or transition stages. The origin of the Orthographic Framework is a core structure. This is assumed to emerge out of the basic grapheme-phoneme knowledge that results from the formation of the alphabetic process. The supposed mechanism is one in which the simple set of correspondences (i.e., the list of the letters and their predominant sounds) is reorganized in the light of the hierarchical structure of the syllable (Seymour, 1993). This entails the segregation of a subgroup of letters, which function as vowels, and the derivation of two sets of consonants, those which can occur in the initial position and those which can occur in the terminal position. This organization is founded on the three-dimensional structure of the syllable and might initially refer only to simple vowels and consonants. The suggestion is that the formation of a core orthographic framework involves a 3D phonological model of the syllable as an initial consonant (IC), vowel (V), terminal consonant (TC) structure, and the establishment of a parallel orthographic representation (i.e., the letters or letter groups that predominantly correspond to the elements of the phonological structure). This structure can be set up by carrying out an internal search for reading words that have the appropriate phonological structure and that are also represented in the logographic system. As these words are located, their positions in the emerging orthographic framework are marked. A search might also be made for words in the logographic store that are composed from the appropriate orthographic elements. Some of these words may be found to be irregular because their pronunciation is in conflict with the dominant correspondences represented in the framework. It is assumed that exceptional items of this kind are located within the structure together with an index that signals the divergence from expected pronunciation. Hence, it is assumed that the framework codes both the general relationship between orthography and phonology and the identities of individual lexical items. The core is regarded as the essential initial requirement for formation of an orthographic system. Once this has been achieved, the direct reading of both words and nonwords that satisfy the core definition can be achieved. It should be possible to demonstrate that all relevant words and nonwords can be read or written without the need for support by alphabetic processes (sequential letter sounding) and that full generalization from taught to untaught items has occurred. This generalization is one property that distin-

guishes orthographic acquisition from logographic acquisition. The capacity to read items directly and without the need for sequential sounding of letters is the feature that distinguishes the orthographic process from the alphabetic process. Beyond the core, orthographic development is held to involve the elaboration of the framework by a process of introduction of increasingly variable and complex structures. This may be in part a matter of the teaching that is provided. If additional vowel groups such as oo and ee are explicitly identified, these will be added into the alphabetic process and eventually into the core, leading to the assimilation of a further set of words that are held in the logographic vocabulary. Other structures may be acquired more or less naturally. These could include some initial consonant groups and final consonant groups. What is required in these cases is an elaboration of the three-part phonological representation of the syllable to represent complex consonantal structures coupled with selection of words from logographic storage and entry of the letter groups into the framework. Other developments are required to accommodate the final -e vowel spellings and further features of vowel lengthening, including consonant doubling and the numerous complex vowel spellings that form the main area of inconsistency in English spelling (Barry & Seymour, 1988). The precise hierarchy of acquisition of the orthographic structure is not known and may be a matter of individual variation. However, it seems likely that the process is extended in time and may not be complete until toward the end of primary schooling. Seymour (1993) presented a function relating reading age to error scores on initial consonant groups, vowels, and terminal consonant groups that had been classified as belonging to the orthographic core or to the more advanced levels. A process of progressive internalization extending over the range 6-to-10 years is suggested for the advanced structures in spelling as well as reading. The criteria for identification of intermediate or advanced levels of orthographic development are similar to those suggested for the core. It should be possible to define the orthographic elements that are added to the framework at each level and then to show that real words or nonwords that contain those elements can be read or spelled by a direct form of processing. In addition, instruction directed toward the elaboration of the framework at a given level should generalize beyond the particular exemplars used in order to bring about improvements in the whole structure. Morphographic Framework As so far described, the orthographic system is mainly to be viewed as a structure that encodes English mono- (and di-) syllables. This system is not capable of dealing with words that are composed of two or more syllables,

including words that have a complex morphemic structure (a stem combined with prefixes and suffixes). Frith (1985) and Morton (1989) and others suggested that mastery of these morphemic aspects of written language is the key feature of the advanced levels of development (misleadingly referred to as orthographic in their accounts). Seymour and Evans (1994a) provided examples of spelling errors produced when premorphographic children (age about 7 years) attempted to write morphemically complex words. In order to accommodate this requirement, the model contains an additional component referred to as the Morphographic Framework. This might be thought of as being established on top of the Orthographic Framework, that is, as a structure that references syllabic entities (represented at the lower level) and their combinations. The development of the morphographic level is, therefore, dependent on the achievement of an adequate structure at the orthographic level. It is also dependent on an interaction with Linguistic Awareness. This could include a phonological influence at the level of syllabic structure and a morphemic influence in establishing the status of segments as word stems or affixes. The framework also requires input from the logographic system where stored word forms provide the exemplars needed to establish the orthographic features of morphemic and polysyllabic spelling. Conclusions In the chapter, I have presented the outline of a theory of orthographic development. The central ideas have been that literacy acquisition involves the formation of a framework that encodes the abstract properties of written language and that this development is dependent on contributions from logographic and alphabetic foundations as well as on an ongoing reciprocal interaction with linguistic awareness. Stages of Acquisition A common feature of theories of literacy acquisition has been a belief that the process may involve a progression through a succession of stages (Ehri, 1992; Frith, 1985; Gough & Hillinger, 1980). This is also true of the dual-foundation model because it is assumed that: (a) the foundations must have reached a certain level before orthographic development can be initiated, and (b) orthographic development must have proceeded some distance before the construction of the morphographic framework becomes possible. However, no necessary sequence in the ordering of the foundation developments is proposed.

It is also hypothesized that the construction of the Orthographic Framework is a stepwise process. Under normal circumstances, the internalization of orthographic information seems to occur automatically and without a requirement for element by element teaching. However, the theory makes the assumption that some structures, notably the core, are developmentally prior to others, that morphographic development is contingent on prior orthographic development, and that there is a hierarchy of acquisition, possibly related to the complexity or consistency or frequency of the orthographic elements. The main implication of the model for the teaching of reading and the remediation of difficulties is that the materials used should be adapted to support the hierarchical structure of development. Reading and Spelling Difficulties A spelling disability (or dyslexia) is defined as a failure to develop a normal orthographic (or morphographic) framework. Such failures could arise for one or other of two reasons. One is that the neural resources underlying the framework are impoverished and that the scope for internalization of information is accordingly restricted. The other is that the development of the framework is distorted or held back as a consequence of a failure at the foundation level. Both of these situations could produce differing dyslexic patterns. So far as the model is concerned, the favored proposal is that there may be individual variations underlying the adequacy of either the logographic process or the alphabetic process. A logographic impairment could reflect an inability to process and store multiletter segments that compose whole words or morphemic or orthographic segments. The effect of this impairment is to curtail the range and quality of the exemplars available to the developing orthographic system. A consequence is that the framework does not internalize word-specific data or information about spelling structures and tends to retain a restriction to an alphabetic letter-sound based level of representation. Thus, a logographic impairment is expected to emerge early in development as a difficulty in acquiring a sight vocabulary and, later on, as a surface dyslexic reading and spelling pattern. An alphabetic impairment might result from a difficulty in acquiring the letters or from problems affecting the systematic application of letter sound knowledge. A difficulty of this kind might be expected to affect orthographic development by inhibiting the establishment of the core structure, especially if there was an accompanying phonological difficulty that affected the capacity to derive a phonemic and a three-dimensional structure for the syllable. If the core of the orthographic lexicon did not develop, the whole of the subsequent development of an organized, phonologically based framework would be compromised. The outcome might be a pattern of

phonological dyslexia in which a word vocabulary is developed (based on the logographic system), although nonwords cannot be read easily (on account of the lack of an orthographic framework) or only by a laborious process (equated with a malfunctioning alphabetic process) (Seymour, 1990; Seymour & Bunce, 1994). According to this account, the contrasting patterns of phonological and surface dyslexia reflect the effect of a selective impairment of one or other of the two foundation processes on orthographic development. The other possibility is that the basis of the orthographic framework is itself impoverished. If this view is taken, the explanation of the contrasting patterns of dyslexia requires some additional assumptions, notably that different kinds of impoverished frameworks are possible. In models such as the one described by Seidenberg and McClelland (1989), the network linking orthographic elements to phonemic elements performs a dual function of deriving generalizations about the correspondence system while storing data about individual words. This dual function depends rather critically on the way the network is constructed, especially the number of hidden units that are interposed between the two levels. It seems possible that one could envisage a range of networks, some of which are specialized in favor of the generalization function and against word-specific storage, and others are specialized in favor of item storage and against generalization. If so, there might be a variation across individuals regarding the direction and degree of specialization that was favored by the available network. The model accordingly favors the view that differing patterns of dyslexia are observable. These could be classified with respect to level, such that one might identify a child as being blocked at the foundation or at an orthographic or morphographic level. They can also be classified in terms of bias, with a distinction between logographic and alphabetic impairments at the foundation level, and a surface versus phonological contrast at the orthographic level. Morphographic impairments might also be found to take differing forms, for example, a distinction between affixes and stems as the primary source of difficulty. Linguistic Awareness Linguistic awareness is held to be interactively involved in the development of the orthographic and morphographic systems at all levels. As orthographic development progresses, there is always a corresponding advance in the relevant area of linguistic awareness. At any stage, a failure of reciprocity, due to an inability to develop the relevant linguistic structures, can pose a barrier against further development. The effects will vary, depending on the level that is affected. A difficulty affecting morphemic awareness affects the establishment of the morphographic framework (thus damaging the

ability to learn to spell complex words), but need not affect the processes occurring at the foundation and orthographic levels. Similarly, a lack of awareness of 2D phonological structure (the onset-rime distinction) will affect the final stages of orthographic development, including classification of consistent and inconsistent word families. The most serious difficulties are those that affect 3D syllabic structure and phonemic segmentation because these have the potential to disrupt the alphabetic foundation, the formation of the orthographic core, and the whole of the subsequent program of orthographic and morphographic development. Implications for Teaching The model has some implications for the teaching of beginning reading or spelling and the remediation of difficulties. A first point is that the componential character of the theory of acquisition helps in the identification of the foci of contrasting instructional methods. Emphasis on whole words (in or out of context) favors the logographic process. Letter sounding develops the alphabetic process and the emergence of phonemic awareness. A stress on word families promotes 2D organization of the orthographic framework and onset rime awareness. Discussion of the derivational structure of complex words is directed toward the morphographic framework and the development of morphemic awareness. The model, therefore, provides a basis for discussion of contrasting instructionally driven pathways in literacy acquisition. In relation to reading difficulties, the important distinctions relate to the foundation and the orthographic and morphographic levels. If development is blocked at the foundation level (corresponding to a reading age of less than 7 years in a UK context), then the appropriate intervention is an attempt to establish the elements of the foundation, with emphasis being directed toward whichever subprocess (logographic or alphabetic) seems more seriously impaired. At more advanced levels, the aim must be the step-by-step construction of an orthographic or a morphographic framework. Hence, a remedial teacher who wishes to work under the guidance of a theoretical model of literacy acquisition requires diagnostic instruments and teaching materials that can be mapped directly onto the components and the levels that have been identified.

Chapter 17 Beginning Reading and Spelling Acquisition in French: A Longitudinal Study Liliane Sprenger-Charolles CNRS & Université René Descartes, Paris Linda S. Siegel University of British Columbia Danielle Béchennec National Institute for Pedagogical Research, Paris Most research on reading and spelling acquisition has been conducted in the English language (see Perfetti, 1994). This state of affairs poses a problem because developmental sequences seem to depend partially on the specific characteristics of languages and orthographies rather than exclusively on the general principles common to all languages (see Frost, 1994). For example, the comparisons between the acquisition of reading in English and in German, a language more transparent than English at the level of grapheme phoneme correspondences, show that German-speaking children use phonological mediation even at the very beginning of reading acquisition, without passing through a logographic stage of nonanalytic, direct visual processing (Wimmer & Goswami, 1994); it is not necessarily the case for English-speaking children (Wimmer & Goswami). Therefore, it is important to examine reading and spelling acquisition in French, a language that, similar to German, has a written system less opaque than English. Some Characteristics of the French Language French is different from English at several levels. Specifically, the patterns of stress for words and phrases and the distinctiveness of words in the
< previous page

next page >

page_340
next page > Page 340
speech stream vary between these languages. An English word has a certain phonetic independence in a sentence because every word has its own stress. In French, stress occurs within a group of words instead of within a word; therefore, word boundaries are not as easy to distinguish in French (see Encrevé, 1988). Another difference between the two languages is in their syllabic structure (Delattre, 1965; Kaye & Lowenstamm, 1984). English typically has closed syllables, and French primarily uses open syllables (see Delattre). These two features of French make the outlines of a word sensitive to contextual influences. The final consonant of a word is generally pronounced with the initial vowel of the following word, for example, pour une autre amie is said /pu/ry/no/tra/mi/ and not /pur/yn/otr/ami/. Therefore, the graphic space used as a boundary for written words may not be congruent with an audible reality. For the spelling system, the basic principles in French are the same as in English. The useful units in writing are graphemes, which can have both phonemic (phonograms) and morphemic references (morphograms; e.g., -s to mark plural; see Catach, 1980; Gak, 1976). In French, phonograms represent 83% of graphemes, according to Catach, who defined four levels of phonograms. The basic units (level zero) are theoretical units representing a class of phonograms. For example, the archiphonogram O covers all realizations of /o/. One of the main features of French is that, at this basic level, there is a large proportion of complex units. Specifically, one third of the 33 archiphonograms are complex units that have no simple equivalents (e.g., the ou /u/, on /ô/ vowels and the ch / / consonant). The three other levels correspond to graphemic realizations characterized according to their frequency. If one assumes that the basic spelling unit is the grapheme and takes into account the contextual rules that govern the pronunciation of some of these units (c + i is read /si/ and c + a is read /ka/), then the grapheme phoneme correspondences are highly regular and predictable in French; for example, o, au, and eau are always pronounced in the same way (/o/). On the other hand, the phoneme grapheme correspondences are less predictable. In fact, in order to spell regular words such as domino (/domino/), landau (/lâdo/), or bateau (/bato/) without error, it is necessary to choose the correct grapheme for the phoneme /o/ among three usual allographes (o, au, and eau). The main objective of the present study is to evaluate the effects of those features of oral and written French on the procedures used by French-speaking beginner readers and writers. General Framework of the Study According to dual-route models (see Coltheart, Curtis, Atkins, & Haller, 1993; Ellis, 1984; Humphreys & Evett, 1985; Paap & Noel, 1991) and their developmental adaptation by Frith (1985, 1986), Morton (1989), Harris and Coltheart

(1986), and Seymour (1986), two procedures govern access to written words. The first involves making a direct match between the written word and the orthographic lexicon, specified as whole words and lexical morphemes. This direct lexical process is called the orthographic procedure in both Frith's (1985, 1986) and Morton's developmental models and does not correspond, in theory at least, to prereading and prespelling logographic strategies, although these two types of processing may be influenced by common factors. Specifically, in the logographic stage, children can directly ''read'' very frequent words that they know by "sight." Unlike the orthographic procedure, the second process is an indirect and nonlexical procedure. In reading, the graphic units (letters, graphemes, or syllabic units) are associated with phonic units (sounds, phonemes, or onset-rimes) that are then assembled. In spelling, phonic units are connected to graphic units. This phonological mediation procedure, called the alphabetic procedure in Frith's and Morton's developmental models, is slow and laborious at the beginning of reading and spelling acquisition. The study we summarize here was designed to examine the development of these procedures in reading and spelling in French. It is possible that the regularity of the grapheme phoneme correspondences in French will lead to a greater reliance on phonological mediation from the first stage of reading and spelling acquisition. In addition, the fact that the word unit is not very accessible in the speech stream may reduce the use of the direct lexical route. Therefore, our main hypothesis is that the first stage of reading and spelling acquisition in French is characterized by the exclusive use of phonological mediation and an absence of influence from such lexical factors as frequency, lexicality, or analogy. This expectation for French is similar to the predictions of Frith's (1985, 1986), Morton's (1989), and Harris and Coltheart's (1986) models, which proposed a stage in which the children use only phonological mediation. On the other hand, this prediction is different from those predicted by the double foundation model of Seymour (1990, 1994) that postulated a co-occurrence of the logographic and alphabetic procedures in the first stage of acquisition. It differs also from the prediction of Goswami and Bryant's analogy-based model (1990) because the lexical effect of analogy is not expected at the beginning. However, in later stages of acquisition, the effects of frequency, lexicality, and analogy should appear, without the disappearance of the regularity effect. Moreover, if processing units used by children in early reading and spelling are letters corresponding to sounds and not graphemes connected with phonemes we should observe an effect of graphemic complexity for regular items. For example, items such as table /tabl/ or lople /lcpl */ (called simple items) should be more accurately read and spelled than items such as route /rut/ or moube /mub/ (called complex items) in which the ou is a two-letter grapheme corresponding to one phoneme (/u/). Although these

page_342
next page > Page 342
trends should be seen in both reading and spelling, the use of phonological mediation should be earlier and more marked in spelling than in reading, in agreement with Frith's (1985, 1986) and Morton's (1989) models. Thus, we predict higher performance in spelling than in reading for all items that can be processed by phonological mediation. Because grapheme phoneme correspondences are more predictable in French than phoneme grapheme correspondences, a fact favoring reading, the advantage of spelling over reading is predicted only for pseudowords. Regular words have several possible spellings but only one possible pronunciation (bateau is always said as /bato/, even though it is possible to spell this word bato, batto, batau, battau, batteau) and may be read better than spelled. Correspondingly, the presumably later developing orthographic direct route should appear earlier and should be more marked in reading; therefore, on variables related to orthographic procedures (frequency, lexicality, analogy), we should see a superiority of reading over spelling (see Frith; Morton). Finally, we can hypothesize that phonological mediation is a mechanism that allows the construction of the orthographic lexicon (Gough & Walsh, 1991; Share, 1995). In such a case, high correlations should be observed between early phonological skills and later orthographic skills. To test this hypothesis, pseudoword and regular word performance were used as measures of phonological skills. As a measure of orthographic skills, irregular word performance was used because reading this type of item cannot, by definition, be entirely dependent on decoding skills. These questions were examined in a study in which we evaluated how reading and spelling procedures develop at the beginning of their acquisition. The analyses compared effects due to phonological mediation, such as regularity and graphemic complexity, with effects due to orthographic procedures, such as frequency, analogy, and lexicality. Evaluating reading and spelling together is optimal for two reasons. The first one is theoretical, as the different developmental models, particularly Frith's (1985, 1986), Morton's (1989) and Goswami and Bryant's (1990), stressed the reciprocal relations between these two skills. The second reason is methodological. Interpreting children's responses in tests that involve reading aloud may be biased by difficulties in listening and transcribing. Recording the data may lessen these risks because it is possible to verify their answers. However, even careful listening cannot completely avoid certain biases resulting, for example, from lexical reconstruction because we are inclined to hear the l of table /table/ even if the child does not pronounce it (see Mowrey & MacKay, 1990; Treiman, Berch, Tincoff, & Weatherston, 1993). This type of risk may be partially avoided when production and reception (i.e., reading and spelling) of the same corpus are studied at the same time. If identical patterns for correct responses and errors are noted in reading and in spelling, the validity of the observations is strengthened.

This study is longitudinal because, in our opinion, longitudinal studies more accurately test developmental hypotheses. If the same participants are examined at different times, the differences observed in performance can be ascribed to developmental changes rather than to sample differences. However, the time period is necessarily compressed because of the rapid development of children's language skills. In tasks that require spelling and reading words and pseudowords, children's performance, especially in spelling, is very poor when they are just acquiring these skills, but, very quickly, performance in reading and, to a lesser extent, in spelling reaches ceiling levels. Therefore, this study observed the development of reading and spelling skills in first-grade children at the middle and the end of the year when their scores were not biased by either floor or ceiling effects. Participants Children had to meet certain criteria to be participants in the study. First, they had to be native French speakers. Second, children with language disabilities, sensorimotor, or neural deficits detected by teachers, psychologists, or medical doctors, were excluded. Finally, children with behavioral problems or those who lacked an adequate opportunity for schooling were not considered. Using these criteria, we examined a group of 100 children at the end of kindergarten. From this group, we chose 60 nonreaders of middle-to-high cognitive level (50th percentile or higher on the Raven Progressive Matrices [Raven, 1947]) from different socioeconomic levels representative of the French population. Their nonreading level was evaluated by the BAT-ELEM. This test was used to confirm that they were nonreaders (Savigny, 1974). It was possible to follow 57 of these children until the end of the first grade. For this first series of observations in primary school (in January), the average age of these children was 6 1/2 years old (SD, 3 mos.). They were enrolled in 20 different classes in nine different schools located in Parisian suburbs and received neither systematic teaching of reading nor teaching of letter-to-sound correspondences in kindergarten. In first grade, the 20 different teachers used mainly mixed methods for reading instruction, with variations in when grapheme-phoneme correspondence rules were explicitly taught. The Tasks The children first read and then spelled the same set of words and pseudowords, with the spelling task always second. Realword reading and spelling were separated by 1 week, with the pseudoword reading and spelling tasks given after an additional week.

For the reading tasks, the procedures used for words and pseudowords were the same. (For pseudowords, children were told they would read [or spell] words that did not exist.) The children took the test individually on a computer that recorded their responses. For the spelling tasks, the words to be spelled were pronounced in context to avoid confusion between homophones (e.g., compte and conte /kôt/). For reading and spelling of both words and pseudowords, no feedback was given to the children. The tasks were given in January and then in June of first grade. The Stimuli Thirty-six words and 16 pseudowords were used (see the Appendix). The selection of words was based on their regularity, graphemic complexity, and frequency. They fell into three categories: regular simple, regular complex, and irregular. The criteria for regularity were based on the French language analyses of Catach (1980) and Gak (1976). The regular words, both simple and complex, contained only frequent phonograms. For the 12 regular simple words, each letter matched a phoneme except for a silent e at the end of a word. The regular complex words contained one of two complex phonograms. These two phonograms, ou /u/ and ch / /, were chosen because they have no simpler equivalents. Other complex phonograms, such as au, which has a simple and more frequent allograph (o), were not used because children could meet difficulties with those phonograms in the spelling task. The irregular words had either a low frequency phonogram with a specific pronunciation (e.g., the first e of femme pronounced /a/) or a silent letter in a nonterminal position (e.g., the p in sept). Irregularities that were limited to the final consonant of a word were avoided because one can correctly read a word such as porc (/pcr */) with a strictly sequential phonological decoding that stops before the last letter. Word frequency was established on the basis of Listes Orthographiques de Base (Basic Orthographic Lists, LOB, Catach, 1984) that draws on several frequency tables (Gougenheim, Michéa, Rivenc, & Sauvageot, 1964; Juilland, Brodin, & Davidovitch, 1970; Trésor de la langue française [French Language Treasure], 1971). Each of the three word categories contained half highfrequency words and half low-frequency words. High-frequency words are in the first 2,000 items of the LOB. The lowfrequency words are not in the LOB but are typically in the spoken vocabulary of first graders, as verified by an oral examination of children of the same age and school level as the ones observed in this study. Finally, the items were matched according to their initial letter and total number of letters. Sixteen pseudowords were constructed and matched in orthographic difficulty with regular words. Half these pseudowords were analogs to the high-frequency realwords, four regular simple, and four regular complex

pseudowords. The initial letter of the high-frequency words was altered to create these analog pseudowords (e.g., mable for table or soche for poche). For nonanalog pseudowords (four regular simple items and four regular complex items), other letters were changed so that there were no analog high-frequency words beginning or ending with the same letters. Results and Discussion Phonological Mediation and Orthographic Procedures in Reading and Spelling Based on certain characteristics of French, we predicted that phonological mediation influences the beginning of spelling and reading without any influence of such lexical factors as frequency, lexicality, or analogy. In the following stages of acquisition, the effects of frequency, lexicality, and analogy are expected to appear and the effects of regularity are expected to remain. The main predictions are summarized in Table 17.1. In accordance with our predictions, the results of the first session (shown in Table 17.2) show that irregular words were not as well read and spelled as regular simple or complex words. Moreover, frequency had no significant effect on performance, and regular words were neither read nor spelled more accurately than their matched pseudowords. This pattern of results suggests that the children primarily used phonological mediation at the beginning of reading and spelling. Lexicality did not matter for reading and actually had a detrimental effect on spelling. Contrary to one of our hypotheses, there was an effect of analogy in reading. Because of the results of regularity and frequency reported previously, which argue against a lexical process, the analogy effect may not TABLE 17.1 Summary of the Predictions for Regularity, Frequency, Lexicality, and Analogy Effects Middle of First End of First Grade Grade Reading Spelling Reading Spelling RW > RW > IW RW > RW > Regularity: Regular words (RW) IW IW IW versus irregular words (IW) HF = LF HF = LF HF > LF HF > LF Frequency: High frequency words (HF) versus low frequency (LF) WD = WD = WD > WD > Lexicality: Words (WD) PW PW PW PW versus pseudowords (PW) AP = NP AP = NP AP > NP AP > NP Analogy: Analog (AP) versus non-analog (NP) pseudowords

Instead, analogy in reading may have worked through the oral response, with analog pseudowords being constructed on frequent words that have easily recoverable articulatory codes. If so, we should not have observed any effect of analogy in spelling because the programming of the articulatory codes should not affect the written response. In fact, this is what we observed in the first session in spelling. Moreover, the correlations between analog and nonanalog pseudowords were very high (.90 in reading and .86 in spelling) and the effect of graphemic complexity a nonlexical factor affected the analog and nonanalog pseudowords in the same way (the interaction between graphemic complexity and analogy was not significant). These observations tend to support the hypothesis that pseudowords, whether they were analog or nonanalog, were processed by an identical nonlexical procedure (i.e., by phonological mediation). Table 17.2, which summarizes the effects observed in reading and in spelling, indicates that, except for the analogy effect in reading, all our predictions for the first session are confirmed. French-speaking children primarily showed the use of phonological mediation in the beginning of reading and spelling acquisition. Nevertheless, we observed changes in performance from the middle of the year to the end of the year that indicate the progressive establishment of the orthographic lexicon (see Table 17.2). In the second session, the high-frequency words were better read and spelled than the low-frequency ones. Also, words were better read than pseudowords. In spelling, the reverse lexicality effect favoring the spelling of pseudowords over words disappeared in the second session. In Frith's (1985, 1986), Morton's (1989) and Seymour's (1986) models, frequency and lexicality effects were interpreted as indicators of logo-

graphic or orthographic procedures. Because we found no effect of frequency and no advantage for words in the first session, the assumption of a logographic lexicon composed entirely of sight words can be rejected. On the other hand, the second session results indicate a progressive development of the orthographic lexicon. The fact that, in this session, words were not more accurately spelled than pseudowords, although they were better read, indicated the negative impact of orthography on spelling. Finally, in accord with our hypothesis, more accurate performance (both in reading and in spelling) was observed for the analog pseudowords in the second session, although this effect did not reach conventional levels of statistical significance in reading (p < .06). These results showed that the children were able to use an orthographic procedure at the end of first grade. However, the orthographic procedure did not entirely replace phonological mediation. We still observed a regularity effect in the second session. This effect was even stronger in session 2 than in session 1 because performance for regular words improved more than for irregular words. The increased importance of phonological mediation between sessions was also evident in the error analysis that found the mean percentage of regularization errors (e.g., album /albcm */, read /albym/ or spelled albome) to increase between sessions from 4.9% to 35.2% in reading and from 27.4% to 64.4% in spelling. These results indicate that, in the second session, at the end of first grade, reading and spelling are controlled by both orthographic and phonological procedures. They do not support the idea of the existence of an orthographic phase in which phonological mediation exerts no influence (see Frith, 1985, 1986; Morton, 1989). Relationships Between Reading and Spelling In the developmental models of Frith (1985, 1986) and Morton (1989), phonological mediation was assumed to be used earlier and more strongly in spelling than in reading, whereas an orthographic procedure should occur earlier in reading than in spelling. Therefore, we might suppose that all the indicators of phonological mediation (i.e., correct responses for regular words and for pseudowords and regularization errors) should be higher in spelling than in reading at the beginning. However, to correctly spell a word, even a regular one, it is necessary to know its orthography; therefore, the superiority of spelling as compared to reading can be expected only for pseudowords, which have no conventional spelling. On the other hand, indicators of the orthographic procedure, such as frequency, lexicality, or analogy, should appear more strongly in reading than in spelling. Consistent with our hypothesis, the frequency effect was more significant in reading than in spelling and the lexicality effect was more pronounced in

spelling, where the pseudowords were spelled more accurately than the words. Two other results support the hypothesis of a greater recourse to orthographic procedures in reading. First, for all words (regular and irregular), the reading spelling difference increased between sessions. In the first session, 29.4% of the reading responses and 26.1% of the spelling responses were correct. In the second session, there were 70.8% correct responses in reading and only 53.2% in spelling. For pseudowords, there was no corresponding reading advantage: 48.2% and 48.4% correct responses for reading and spelling, respectively, in the first session and 80.0% and 76.3% in the second. The second supportive result was the increasing impact of orthography on spelling compared with reading. The global deficit of spelling relative to reading was 5.6% for simple regular words, 12.3% for complex regular words and 13.4% for irregular words. The difference for irregular words between reading and spelling increased from 2.2% in the first session to 24.7% in the second. These results suggest that the orthographic procedure was more marked in reading than in spelling and that its significance to the benefit of reading increased with time. Contrary to our hypothesis of an earlier and stronger recourse to phonological mediation in spelling as compared to reading in the beginning of acquisition, the results of the correct-response analysis did not show better spelling of pseudowords. This result might be due to the fact that graphemic complexity had a positive impact on pseudoword reading but not on pseudoword spelling. This interpretation was reinforced by the results obtained in another study in which we observed better results in the first session in the spelling of pseudowords that contained only simple graphemes (Sprenger-Charolles & Siegel, in press). It is possible that the results of other studies finding a superiority of reading over spelling were influenced by graphemic complexity. (For English-speaking beginners, see Seymour, 1990; Seymour & Evans, 1991; for German-speaking beginners, see Wimmer & Hummer, 1990.) In the present study, an earlier and more marked use of phonological mediation in spelling might be inferred from the regularization error analysis that showed more regularization errors in spelling than in reading in both sessions (35.2% in spelling versus 4.9% in reading in the first session and 64.4% and 27.4% for the second session). Table 17.3, which summarizes the entire results, shows that phonological mediation is used more strongly and earlier in spelling than in reading, whereas the reverse is observed for the orthographic procedure. However, beyond these differences, the correlations between reading and spelling were all positive and significant: first session, r = .70 for pseudowords, .82 for regular words and .65 for irregular words; second session, r = .85, .80, and .72. These correlations show that, beyond their differences, there are also strong links between reading and spelling, at least at the beginning of their acquisition in French.

The Processing of Complex Graphemes If processing units used by children at the beginning of reading and spelling acquisition are letters in relation to sounds, and not graphemes in relation to phonemes, we should observe an effect of graphemic complexity for regular items, which then progressively disappears in both reading and spelling. In fact, we observed a difference between reading and spelling with regard to the effect of graphemic complexity. Graphemic complexity had a detrimental effect only on performance for word spelling in the first session. In June (the second session), in the pseudoword reading task, we even observed a superiority of the complex items as compared to the simple ones. The results are summarized in Table 17.4. They show that, except for the word spelling task in the first session, the children seemed to process graphemes rather than letters. These results might have been due to the processing of complex graphemes per se or the result of compound factors. To check this, we compared the processing of simple and complex graphemes in complex items. In these comparisons, we took into account the mean percentage of orthographically correct responses for complex graphemes and for simple graphemes with the exception of the final silent e in word reading and spelling. The same comparison was made for pseudowords. However, because pseudowords have no canonical spelling, we took into account the mean percentage of phonologically correct responses.

Significant differences are indicated by ** for p < .01 or * for p < .05. This direct comparison between simple and complex graphemes showed a very clear developmental trend for spelling. Complex graphemes were less well spelled than simple graphemes in the January session both for words and pseudowords; in the June session, there was no difference between simple and complex graphemes. These results show that children progressively set up complex graphemes and that they were rapidly using graphemes, not letters, in spelling. In reading, simple graphemes were better processed than complex graphemes only in the pseudoword task during the January session, suggesting that children applied mainly graphemes in reading. Moreover, complex graphemes were more accurately processed than simple ones in one case (word reading in June). This last result was not observed in the spelling tasks. These results differ slightly for overall accuracy from those discussed previously. Such differences might result from the fact that, in this complex grapheme analysis, only correct graphemes were assessed. For example, in table, read or spelled tabal(e), all the expected graphemes were correct even though the response for the complete word was incorrect. The Role of Phonological Mediation in the Construction of the Orthographic Lexicon If phonological mediation is a mechanism allowing the setting up of the orthographic lexicon, we should observe a connection between items that respond to the early phonological procedures and those that respond to later lexical-orthographic procedures. For example, we should observe a connection between early success on regular words and pseudowords and later success in reading and spelling of irregular words. In fact, we observed significant positive correlations between performance on regular words and pseudowords in January and performance in June for all types of items, including irregular words. However, scores for

Significant differences are indicated by ** form p < .01. irregular words in January were not correlated with those for regular words and pseudowords in June (see Table 17.5). We also observed positive correlations between the regularization errors, another indicator of phonological procedures, and correct responses in January for both reading (r = +.54) and spelling (r = +.42). These results were consistent with those of some other studies showing that reading and/or spelling performance on pseudowords or regular words, including regularization errors, predict all further results in reading and in spelling, even for irregular words (see Byrne, Freebody, & Gates, 1992; Foorman, Francis, Novy, & Liberman, 1991; Foorman, Jenkins, & Francis, 1993; Gough & Walsh, 1991; for a review, see Share, 1995). The reverse has not been established. The capacity to read or spell irregular words does not seem to be a predictor of future skills in reading and/or spelling. General Discussion To evaluate whether French first-grade children use the indirect phonological route or the direct orthographic route, we asked them to read and spell items we had selected or constructed so as to show the procedure required to read and spell them. For example, sensitivity to frequency or lexicality is generally considered an indicator of direct matching between a word and the orthographic lexicon because a high-frequency word, unlike a pseudoword or a low-frequency word, might have an entry in the orthographic lexicon of the beginners. An analogy effect for pseudowords also suggests this lexical procedure because analog, not nonanalog, pseudowords share their orthographic body with the high-frequency words from which

next page > Page 352
they were constructed (e.g., mable from table). On the other hand, differences between regular and irregular words or differences between regular words, according to whether they contain simple or complex graphemes, are indicators of phonological mediation. The principal hypothesis of this study on reading and spelling acquisition was that we should find signs of virtually exclusive use of the nonlexical, indirect phonological route in the first stage of acquisition. This is because, in French, the correspondences between grapheme and phoneme are regular and because the word unit is not very easy to determine in the speech stream. The data support our prediction. In the first session, performance was affected by regularity but not by frequency or lexicality. Thus, regular words were better read and better spelled than irregular ones, and regularization errors (e.g., album /albom/ read /albym/ or spelled albome) were made with the irregular words. Furthermore, high-frequency words were not more accurately read or spelled than low-frequency ones, and comparisons between words and pseudowords showed no word superiority effect. The pattern of results was completely consistent with the hypothesis of an exclusive phonological stage, with the single exception that there was an effect of analogy in early reading; analog pseudowords were better read, but not better spelled, than nonanalog pseudowords. This effect, observed in reading at a time when neither frequency nor lexicality had any impact on performance, may be the result, as we have suggested, of a facilitation of the oral response rather than a true reading effect. The analog items were derived from high-frequency words that may have preprogrammed articulatory codes. This interpretation was confirmed by three aspects of the data. First, there was no effect of analogy in spelling, in which the programming of the articulatory codes cannot have a direct effect. Second, there were very high correlations between analog and nonanalog pseudowords in reading and in spelling. Third, graphemic complexity, which is a nonlexical factor, affected analog and nonanalog pseudowords in the same manner. These results indicate that analog and nonanalog pseudowords were processed in the same manner, by phonological mediation. Taken together, the results show that French-speaking children mainly use phonological mediation at the beginning of reading and spelling acquisition. These results then support the hypothesis of a phonological process as the sole operative process in this early stage of reading and spelling acquisition as predicted in Frith's (1985, 1986), Morton's (1989), and Harris and Coltheart's (1986) models. Alternatively, they are inconsistent with Seymour's (1990) hypothesis concerning the coexistence of logographic and phonological procedures at the beginning of acquisition. Although we found an early stage in reading and spelling acquisition during which the children mainly use phonological mediation in French, we also concluded that an orthographic lexicon is quickly constructed. At the end of
< previous page

page_353
next page > Page 353
the first grade, words were better read than pseudowords, and frequency had an impact on the reading and spelling. Because these effects were not seen earlier, they cannot be interpreted as the result of a logographic strategy. Rather, they indicate that an orthographic lexicon gets progressively constructed, especially in reading. The fact that we did not observe any lexicality effect in the second session in spelling is evidence of the negative impact of orthography on the spelling of even regular words. Even if children in the later stage of reading and spelling acquisition are able to use a procedure of direct matching between a word and its lexical entry, it does not entirely replace phonological mediation. This can be seen by the regularity effect observed at the end of the first grade, which was even stronger that the one we had observed in January. The difference between regular and irregular words increased, as did the mean number of regularization errors. These data do not corroborate the existence of an orthographic stage in which phonological mediation plays no role (see Frith, 1985, 1986; Morton, 1989). Also contradicting the Frith and Morton models is the fact that there was no indication of a logographic stage, one in which words known ''by sight'' would be read "holistically," whether regular or not. One may argue that our first session was already too late in the development of the reading process to show logographic strategies. However, 6 months earlier, the children chosen for this study were all nonreaders, according to their results on a standard reading test. The lack of a logographic stage in French (see Rieben, 1993; Sprenger-Charolles & Bonnet, 1996) may be explained by some of the features of the orthography (the regularities of the grapheme-phoneme correspondences) and the language (the difficulty of recognizing the word units in the speech stream). However, logographic reading might be rare in all languages (for German, see Wimmer & Goswami, 1994; Wimmer & Hummer, 1990; for English, see Siegel, 1985). Another hypothesis of the present longitudinal study is that phonological mediation allows the construction of the orthographic lexicon (see Share, 1995). This hypothesis is corroborated by the discovery that early phonological decoding skills were predictive of later reading and spelling performance, including performance with irregular words, but not the reverse. Moreover, correlations between correct responses and regularization errors were, in the beginning of reading and spelling acquisition, positive and significant. A similar result has already been noted in an earlier longitudinal study (Sprenger-Charolles & Casalis, 1995). Similar tendencies were observed in another longitudinal study. In that study, we defined two groups of participants: a group of "expert" spellers and a group of "poor" spellers (see Sprenger-Charolles, Siegel, & Béchennec, in press), established according to their scores in an orthographic verification task. The experts in spelling are the participants who, at the end of

second grade, made no errors in this task. Supposedly, they have a better orthographic lexicon than the poor spelling group. The developmental trajectory of these two groups provides much support for the contribution of the phonological mediation procedure in the establishment of the orthographic lexicon. First, the future experts in spelling were children who obtained higher scores than the other participants in two metaphonological tasks at the beginning of their last year of kindergarten; at the same time, those participants differed neither by their nonverbal cognitive level nor by their vocabulary level. Second, more than a year later, at the end of first grade, the future experts in spelling were characterized by a strong reliance on phonological mediation in silent reading as well as in oral reading and in the spelling of dictated words. Third, at the time when the two groups were formed, at the end of second grade, the experts in spelling scored higher than the other participants in a silent and in an oral reading comprehension task, but not in a spoken comprehension task.1 These results clearly showed that (a) only reading specific components at the level of word recognition differentiated those two groups of children, (b) the early use of phonological mediation contributed to the establishment of the orthographic lexicon, and (c) early metaphonological skills made it easier to set up the phonological procedure. These results might be explained by the fact that phonological mediation permits processing of all regular words, known or unknown, as well as words that do not exist. Using phonological mediation and confronting the responses obtained by this procedure with orally known words may permit the children to infer correspondences between graphemes and phonemes (GPC). Noncontextual correspondences are probably learned before contextual ones (for example, c + i read /si/, whereas c + o is read /ko/). However, as indicated by our data, some high-frequency contextual correspondences may be learned at the same time as simpler ones (for example, o + u, read /u/). As French is a very regular language at the level of GPC correspondences, the majority of words might be learned that way. As for irregular words, it is possible to consider that, on the one hand, these items have only one irregular aspect (for example, in femme /fam/, only the first e has an irregular pronunciation). On the other hand, the frequency of the irregular graphemes per se and the frequency of the words in which they are included, might influence performance. Thus, children can learn progressively some rare correspondences (for example, e + m of femme is read /a/ as in the -emment adverbs such as fréquemment/frekamâ/). In this case, the inference of such a correspondence can be reasoned as follows: The word /fem/ does not exist, but a very near word exists (/fam/), so e must be read a in this context. In this manner, children 1 These tasks were elaborated by Lecocq (1996). See also Lecocq, Casalis, Watteau, and Leuvers (1996).

probably learn the many relations between orthography and phonology, including the more opaque relations. Based on the frequency of the graphemes and also on the word frequency, strong associations between phonological units and orthographic units are thus created, permitting the progressive elaboration of an orthographic lexicon. However, even when the directmatching route between a word and the orthographic lexicon is functional, children may still use phonological mediation, which becomes more and more automatic as the associations permitting the establishment of the grapheme phoneme correspondences are reinforced (see Perfetti & Zhang, 1995). This learning scheme has the advantage of allowing the integration in the first stage of the phonological mediation procedure of strategies using local alphabetical cues (see Ehri, 1992; Harris & Coltheart, 1986; Stuart & Coltheart, 1988). However, it has two limitations. First, it does not allow an explanation of how, through associations, through the reinforcement of the strength of some links, a qualitative change appears. Second, this explanation cannot be used for spelling, in which, unlike reading, the oral lexicon is not of great help.2 For example, knowing /bato/, which is the phonological form of the word bateau, can facilitate the reading, but not the spelling, of this word. This is due to the asymmetry of the grapheme phoneme and phoneme grapheme correspondences. Whereas only one reading is possible for this word, /bato/ could be spelled correctly, according to usual phonological rules, ba(t)to or ba(t)tau as well as ba(t)teau (with one or two ts). Thus, the orthographic procedure develops later in spelling than in reading. Our results have corroborated that hypothesis. On the one hand, the frequency effect was greater in reading than in spelling, and if the lexicality effect was more marked in spelling, it was to the detriment of words. On the other hand, the words, but not the pseudowords, were better read than spelled; the difference between word reading and word spelling increased between sessions. Finally, the negative impact of orthography in spelling compared to reading was more noticeable in the spelling of complex regular words and even more marked in the spelling of irregular words, with this last trend increasing over time. These data are indicators that the orthographic procedure is more strongly used in reading. The reverse trend was noted for phonological mediation in the fact that more regularization errors occurred in spelling as early as the first session. These results are in accordance with those predicted by Frith's (1985, 1986) and Morton's (1989) models. We observed another difference between reading and spelling in the processing of complex graphemes. At this level, our hypothesis is that, if the processing units used by children at the beginning of acquisition are letters in relation to sounds, and not graphemes in relation to phonemes, 2 Except in the case of morphological marks. For example, if you know the word chaton (kitten), you can correctly spell chat with a t (see Leybaert and Alegria, 1995, on this topic).

the graphemic complexity effect should disappear over time. In fact, the negative impact of graphemic complexity was observed only in the first session, particularly in spelling. In the second session, complex graphemes never hurt the children's performance and complex graphemes were processed even better than simple graphemes in word reading. These results might be explained by the fact that, if the basic unit of GPC processing is the grapheme and the total number of letters is the same, when the item contains one or more digraphs, the children have fewer units to assemble than when the items are only composed of simple graphemes, for example, four units in route compared to five in table. In this case, they also have fewer phonemic units to process to give an oral response (three in the first case and four in the second). Alternatively, in spelling, the use of phoneme grapheme correspondences when items have complex graphemes necessitates the transformation of a simple unit (a phoneme) to a complex one (a digraph). This latter operation might have a higher cognitive cost. Beyond the differences noted between reading and spelling, the correlation analysis indicates a joint development of these two skills. More generally, our data show that phonological mediation is dominant in the first stages of reading and spelling acquisition in French and that the use of this procedure contributes to the establishment of the orthographic lexicon. Conclusion In sum, our data show that the primary process in the early stage of reading and spelling acquisition in French is phonological mediation and that this mediation contributes to the development of the orthographic lexicon. Our results do not correspond completely with any of those predicted in current developmental models. They are partly consistent with those stage models that predicted the existence of a phonological mediation stage (see Frith, 1985, 1986; Harris & Coltheart, 1986; Morton, 1989; Seymour, 1986). However they differ from these models in (a) finding no clear evidence of a logographic stage (see also Sprenger-Charolles & Bonnet, 1996), and (b) observing, after the phonological mediation stage, a stage in which phonological and orthographic procedures coexisted, with the weight of the orthographic procedure being less marked in spelling than in reading.
