The Varieties Of Orthographic Knowledgei

The role of orthography in reading and writing is not a new topic of inquiry. For example, in 1970 Venezky made a seminal contribution with The Structure of English Orthography in which he showed how both sequential redundancy (probable and permissible letter sequences) and rules of letter-sound correspondence contribute to orthographic structure. In 1980 Ehri introduced the concept of orthographic images, that is, the representation of written words in memory, and proposed that the image is created by an amalgamation of the word's orthographic and phonological properties. In 1981 Taylor described the evolution of orthographies in writing systems-from the earliest logographies for pictorial representation of ideas to syllabaries for phonetic representation of sounds to alphabets for phonemic representation of sounds. In 1985 Frith proposed a stage model for the role of orthographic knowledge in development of word recognition: Initially in the logographic stage a few words can be recognized on the basis of partial spelling information; in the alphabetic stage words are. recognized on the basis of grapheme-phoneme correspondence; in the orthographic stage spelling units are recognized automatically without phonological mediation. For an historical overview of research on visual processing of written language spanning the earliest records of writing to the early work in experimental psychology, see Venezky (1993).

In 1972 Kavanagh and Mattingly edited Language by Eye and by Ear which contained important linguistic studies of the orthographic system.

In 1990 Adams applied connectionism to an analysis of the orthographic processing of skilled readers: letter patterns emerge from the association units linking individual letters.

This volume unites spelling and word recognition -- two areas that have largely remained theoretically and empirically distinct. Despite considerable advances in the investigation of processes underlying word perception and the acknowledgement of the seminal importance of lexical access in the reading and writing processes, to date the development and functioning of orthographic knowledge across both encoding and decoding contexts has rarely been explored. The book begins to fill this void by offering a coherent and unified articulation of the perceptual, linguistic, and cognitive features that characterize an individual's advancing word/orthographic knowledge, providing evidence for a common knowledge base underlying spelling in writing and word recognition in reading. From a developmental perspective, the studies and syntheses presented in this volume blend insights from psychology and language study with those from clinical and classroom observations. These insights help explain how individuals, from preschool through adolescence, develop knowledge of the orthographic system underlying word structure in English and how they apply this knowledge in actual writing and reading contexts. Implications are drawn for the assessment and teaching of spelling, vocabulary, and word analysis from primary through middle grades.

This volume is the first of a two-part series dealing with the theoretical, definitional, methodological, and developmental issues involved in investigating the role of orthography in reading and writing. Although research on orthography has a long history in experimental psychology and neuropsychology, it was relatively neglected during the past decade when researchers turned their attention to phonological processes in literacy. However, interest in orthography is reemerging as the research reported in this series demonstrates. Taken together, the two volumes report evidence for shared and independent genetic pathways, shared and independent electrophysiological brain activity, and shared and independent behavioral indices of orthographic and phonological processes and emphasize the similarities and differences of orthographies across languages. Volume I proposes a theoretical framework based on the multiple dimensions of orthographic knowledge for guiding future research. For basic and applied researchers and graduate students in cognitive and developmental psychology, neuropsychology, linguistics, and education.

Originally published in 1982. This book charts the reading progress of ten children through their first three years at school, concentrating particularly on their problems and the ways they coped with them. The author uses these case studies to analyse the children's understanding, experience of behaviour associated with literacy, and developing knowledge of spelling in the early stages of learning to read. Her analysis of the children's difficulties and successes, against the background of their home experience, classroom activities and teachers' methods, calls in question any simplistic generalisations about the ways that background and teaching method can affect reading progress.

The present volume is based on the proceedings of the Advanced Study Institute (AS I) sponsored by the North Atlantic Treaty Organization (NATO) held in Alvor, Algarve, Portugal. A number of scholars from different countries participated in the two-week institute on Cognitive and linguistic aspects of reading, writing, and spelling. The present papers are further versions with modifications and refinements from those presented at the Advanced Study Institute. Several people and organizations have helped us in this endeavor and their assistance is gratefully acknowledged. Our special thanks are to: the Scientific Affairs division of NATO for providing the major portions of the financial support, Dr. L.V. da Cunha of NATO and Dr. THo Kester and Mrs. Barbara Kester of the International Transfer of Science and Technology of the various aspects of the institute; and (ITST) for their help and support the staff of Hotel Alvor Praia for making our stay a pleasant one by helping us to run the institute smoothly.
