Physicians have been treating hyperactivity in children with drugs as if it were a disease instead of a collection of symptoms which require exhaustive diagnostic tests to determine the underlying problem. (DB)

The exploratory study examined patterns of regional cerebral blood flow in a surface and a deep dyslexic during reading. Significant differences in gray matter blood flow were found between subjects and normal controls. Also differences existed between the surface and deep dyslexic in the distribution of cortical perfusion. (Author/DB)

Measured were variations in the brain activity of a child with suspected cerebral disturbance, EEG abnormality, and academic retardation while performing different cognitive activities. (Author/KW)

The article reports research supporting a view which sees learning disabilities as resulting from the interplay between a poorly elaborated knowledge base (especially in language related domains), the biologically determined efficiencies of such processes as encoding, and the physical and social meaning attached to performance (i.e. the context).…

In response to Coles (EC 220 146), the article examines evidence of the roles of intrinsic biological characteristics and the environment in learning disability and suggests that learning disability is a biological susceptibility manifested in an environment promoting its expression. (DB)

An unusual birth history and an accumulation of other minor deficits were found to be present to a greater degree in underachievers than in children who achieve up to their potential. (Author/KW)

The possibility that four famous men--Thomas Alva Edison, Woodrow Wilson, Hans Christian Andersen, and Leonardo da Vinci--might have been reading disabled is considered by examining information concerning: (1) biographical records, (2) cognitive characteristics, (3) neuropsychological characteristics, and (4) biological characteristics. (Author/DB)

Characteristics of the aggressive, severely behavior disordered (BD) child are discussed, with a focus on classification and identification criteria. Additional factors directly related to the behavior of an aggressive, severely BD child are also considered: biological factors, familial factors, cognitive factors, frustration (specifically…

Proposed is an approach to child development which holds that intellectual capacity, neuromuscular development, language development, and temperament are overlapping areas; and considered are often unrecognized behavioral aspects of temperament. (MC)

A study that compared 20 children with reading difficulties (RD) with severe executive processing deficits, 16 with RD with moderate executive processing ability, 20 with high ability, and 20 who had moderate sentence span scores, found a domain-general system may partially contribute to poor working memory in children with RD. (Contains…

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…

Composite reading performance data from 223 pairs of identical twins and 169 same-gender fraternal twins in which at least one member was classified with reading disability were subjected to multiple regression analysis. Results indicated that the genetic etiology of reading disability differs as a linear function of IQ. (Contains extensive…

This article introduces a special issue dealing with selected aspects of writing disorders. It provides an overview of following articles and issues confronting the written language field, including definitional issues, assessment issues, neurodevelopment components, brain-behavior linkages, lifespan issues, and interventions. Recommendations are…
