Explaining Individual Differences in Reading Theory and Evidence New Directions in Communication Disorders Research Series

Research into reading development and reading disabilities has been dominated by phonologically guided theories for several decades. In this volume, the authors of 11 chapters report on a wide array of current research topics, examining the scope, limits and implications of a phonological theory.

The chapters are organized in four sections. The first concerns the nature of the relations between script and speech that make reading possible, considering how different theories of phonology may illuminate the implication of these relations for reading development and skill. The second set of chapters focuses on phonological factors in reading acquisition that pertain to early language development, effects of dialect, the role of instruction, and orthographic learning. The third section identifies factors beyond the phonological that may influence success in learning to read by examining cognitive limitations that are sometimes co-morbid with reading disabilities, contrasting the profiles of specific language impairment and dyslexia, and considering the impact of particular languages and orthographies on language acquisition. Finally, in the fourth section, behavioral-genetic and neurological methods are used to further develop explanations of reading differences and early literacy development.

The volume is an essential resource for researchers interested in the cognitive foundations of reading and literacy, language and communication disorders, or psycholinguistics; and those working in reading disabilities, learning disabilities, special education, and the teaching of reading.

Susan Brady is a Professor of Psychology at the University of Rhode Island. Her basic research focuses primarily on phonological factors in reading ability. In addition, in applied research she investigates the ingredients, such as teacher knowledge, necessary for improving reading achievement in the primary grades.

David Braze, a linguist, concentrates his research on the cognitive bases underlying ability to comprehend speech and print. He employs online methods, including monitoring eye-movements during reading, to investigate bottlenecks in comprehension. Likewise, he explores how characteristics of text interact with individual differences in cognitive factors to impact reading comprehension.

Carol Fowler is a Professor of Psychology at University of Connecticut. Her research includes an emphasis on the relation between speech production and perception, and the implications of that relation for phonological theory. One aspect of that research explores the nature of the phonological structures accessed by skilled readers of a variety of writing systems.

The three editors are all Senior Scientists at Haskins Laboratories in New Haven, Connecticut.
