The author, searching for possible neurological anomalies behind a learning disability, focuses on the theory that faulty lateralization is implicated in reading difficulties. (Author)

The article reviews proposed causes and observable symptoms that characterize dyslexia, concluding that individualized analysis and specialized treatments are required and that, until an operational definition can be agreed upon, use of the label "dyslexia" is counterproductive. (DB)

This paper examines the influence of Norman Geschwind's model of connectionism, in which complex functions are built up by connecting primary areas in the brain, and notes his studies of the effects of disconnection on dyslexic individuals. Connectionist-based behavioral studies are reviewed, focusing on intracortical association connections and…

Preliminary results of a survey of 10-year-old children (N=12.905) given a variety of educational and cognitive tests relevant to diagnosis of dyslexia have shown that distributions of scores are incompatible with the hypothesis of normal variation, suggesting that dyslexia involves some kind of anomaly. (Author/DB)

The article summarizes findings of research on individual differences in reading ability, noting the primary effects of lack of phonological awareness on the ability to phonologically segment, analyze, and synthesize the speech stream. Other sources of individual differences are also addressed: early visual processes, naming processes, context,…

Over 500 men who attended an independent school for children with developmental dyslexia were followed up from one to 38 years after they left the school. Socioeconomic status and IQ were not predictive of adult outcome. Severity of reading problem upon entrance and academic and remedial progress while at school were predictive of adult…

The eight-year-old boy was taught to use a memory strategy for determining correct symbol representation through behavior modification involving accurate recognition and production of letters and digits. Decrease in frequency of letter and digit reversals demonstrated utility of the mnemonic method and confirmed the reversal/directional…

Research shows that persons with dyslexia may have bilateral neural involvement in spatial processing that interferes with the left hemisphere's processing of its own specialized functions. This results in deficient linguistic, sequential cognitive processing. (MLH)

Dyslexia is often accompanied by secondary emotional reactions by the child himself or by family members. (DB)

Four cases histories are offered as examples of what happens to learning disabled children in later life if not correctly diagnosed and given appropriate remedial instruction. (DB)

Ways of diagnosing dyslexia are discussed along with the developmental symptoms, which include balancing and hearing deficiencies, reversal of letters or words and unusual posture. Medical treatment with antihistamines and other drugs is described. Approximately 75 percent of individuals are shown to respond favorably to therapy. (CM)

Follow-up information is presented on a severely dyslexic young woman who describes her difficulties in learning how to read and write and in adjusting to the demands of a two-year college course. The author cites passages from correspondence with her to point out her progress. (CL)

Two articles contain the case studies of a gifted learning disabled elementary-age student and of a gifted dyslexic adult. (SB)
