This article discusses six theoretical frameworks of disability which dominate studies of dyslexia: (1) the biomedical, (2) the biopsychosocial, (3) the social model, (4) the critical realist, (5) the post-structuralistic, and (6) the neurodivergent approach. The aim of this paper is to demonstrate how models of disability alter our understandings…

This article presents an operational, inclusionary definition of dyslexia constructed by the Orton Dyslexia Society Research Committee and others. Each clause of the definition is explained in terms of relevant research findings. The definition attempts to identify unique factors of reading disability, independent of its common association with…

This paper elaborates on components of a working definition of developmental dyslexia proposed in 1995 by G. R. Lyon. The 2003 revised definition, based on converging scientific evidence, was developed by a working group of the International Dyslexia Association. The new definition notes the condition's neurobiologic origin and typical presence of…

This article reviews evidence for seven central questions about the role of naming-speed deficits in developmental reading disabilities. Cross-sectional, longitudinal, and cross-linguistic research on naming-speed processes, timing processes, and reading is presented. An evolving model of visual naming illustrates areas of difference and areas of…

This review essay of the book, "Developmental Dyslexia: Neural, Cognitive and Genetic Mechanisms," edited by Christopher H. Chase and others, describes the book's review of the research literature in these three fields and its efforts to integrate the divergent research strands. The book is recommended to researchers in dyslexia, clinicians, and…

This article summarizes work in progress at the Bowman Gray School of Medicine (North Carolina) on the structure and physiological profiles of reading disability and relates the findings to core left-hemisphere language functions. Data add evidence of the structural anomalies associated with dyslexia and evidence of its heritability, especially of…

Shares information about the latest technology which offers expanded insights into the reading process and how the brain operates. (MG)

Introduces a series of articles on the prevention and treatment of dyslexia in Europe. The benefits of the Cooperation Scientifique et Technologique (COST), a framework for a research and development collaboration that promotes coordination of national research at the international level, is also discussed. (CR)

Examines previous hypotheses of the causes of dyslexia. Proposes that dyslexia results from a subtle language deficiency rather than from defects in the visual system. Discusses current theories and assesses instructional strategies for dyslexics. (ML)

This article introduces two conference papers (EC 607 450 and 451) which discuss the link between basic research into brain structure and function and the applied issues of instructional intervention in dyslexia. The papers, based on longitudinal studies at the Bowman Gray School of Medicine (North Carolina), were presented at a Middle Tennessee…

This monograph is a synthesis of research findings of the National Institute of Child Health and Human Development research program concerning how children learn to read, why some children and adults have difficulties learning to read, and effective ways to help children learn to read. The review covered studies performed over the last 33 years at…

This monograph examines three approaches to intelligence that include cognitive processing components and relates each to assessment and interventions with students having reading disabilities. The first, Sternberg's Triarchic theory of intelligence (1985), includes three subtheories, contextual, experiential, and componential. The second, the…

This book aims to interpret recent research on dyslexia into practical information for those who work with individuals with dyslexia. Chapter 1 summarizes new information about how genetic codes determine brian development and how differences in brain structure cause dyslexia. Chapter 2 explains the perceptual and emotional nature of dyslexia.…

This volume, the proceedings of a 1992 conference, presents 14 papers which take a neuropsychological approach to attention deficit disorder, attention deficit disorder with hyperactivity, and learning disabilities. Papers have the following titles and authors: "A New Conceptual Model for Dyslexia" (Sally E. Shaywitz et al.);…
