It has been commonly agreed that developmental dyslexia in different languages has a common biological origin: a dysfunction of left posterior temporal brain regions dealing with phonological processes. Siok, Perfetti, Jin, and Tan (2004, "Nature," 431, 71-76) challenge this biological unity theory of dyslexia: Chinese dyslexics show no deficits…

In this paper we studied the effectiveness of the writing criteria that are proposed to be applied during the construction of physics texts so that students with dyslexia do not confront reading difficulties with them. The effectiveness of the criteria has been assessed by the accomplishment of an investigation among students with and without…

The general magnocellular theory postulates that dyslexia is the consequence of a multimodal deficit in the processing of transient and dynamic stimuli. In the auditory modality, this deficit has been hypothesized to interfere with accurate speech perception, and subsequently disrupt the development of phonological and later reading and spelling…

The introduction, in the United Kingdom, of the Special Education Needs and Disabilities Act (SENDA) published and approved in 2001, has removed the exemptions given to educational institutions by the Disabilities Discrimination Act (DDA) of 1995. This applies to learning web sites and materials that must now undergo "reasonable…

The human brain is not a passive organ simply waiting to be activated by external stimuli. Instead, we propose that the brain continuously employs memory of past experiences to interpret sensory information and predict the immediately relevant future. The basic elements of this proposal include analogical mapping, associative representations and…

Participants report briefly-presented words more accurately when two copies are presented, one in the left visual field (LVF) and another in the right visual field (RVF), than when only a single copy is presented. This effect is known as the "redundant bilateral advantage" and has been interpreted as evidence for interhemispheric cooperation. We…

A total of 83 children with different special educational needs (SEN) assessments were contrasted with a control group (N = 40) without special needs on measures that aimed to identify potential areas of strengths as well as weaknesses in these SEN groups. Carefully selected groups of dyslexics, dyspraxics, children with specific language…

Theoretical, diagnostic, and remedial issues related to polyglot dyslexia (i.e., difficulties in reading experienced in both languages spoken by bilinguals) are considered. Theoretical causes of dyslexia, research done with neuropsychological and neurolinguistic aspects of bilingualism, the literature on polyglot aphasia, and theoretical concerns…

Described is the Aston Index, a pilot instrument designed for screening dyslexic-type language difficulties in young children. It is explained that the index consists of three forms to test children at three stages of development (such as those who have been in school about 6 months), that it represents an "integrated" approach, and that it…

The annotated bibliography on dyslexia contains approximately 50 abstracts and associated indexing information for documents published from 1966 to 1973 and selected from the computer files of the Council for Exceptional Children's Information Services and the Education Resources Information Center (ERIC). It is explained that titles were chosen…

Hypotheses accounting for the pattern of deficits in specific developmental dyslexia were examined. The theory postulates that the disorder reflects a lag in maturation of the central nervous system, particularly the left cerebral hemisphere. The hypotheses in question predicted that skills developing ontogenetically earlier (visual-motor and…

The selected bibliography of reading methods and problems contains an explanation of indexing and approximately 100 abstracts to be drawn from the computer file of abstracts representing the Council for Exceptional Children Information Center's complete holdings as of August, 1972. Abstracts are said to be chosen using the criteria of availability…

This series of nine articles on dyslexia, or specific language disability, originally appeared in the Baltimore "Evening Sun" in response to increasing public interest regarding reading disabilities and handicaps. These articles summarize the methods of identifying and teaching these children and discuss the school's common failure to identify and…

The case study explores the detrimental influences of a father's dyslexic condition on the emotional development of his children and on his family's functioning. (Author)

Reviews research suggesting that visual dyslexia may be treated by wearing tinted glasses. Discusses studies seeking to determine whether dyslexia is due to a visual deficit or a linguistic deficit, and maintains that more research needs to be done in this area. (MM)
