Background: Developmental dyscalculia is a heterogeneous disorder with largely dissociable performance profiles. Though our current understanding of the neurofunctional foundations of (adult) numerical cognition has increased considerably during the past two decades, there are still many unanswered questions regarding the developmental pathways of…

Most of 32 learning disabled children (seven to 14 years old) with neurological lateralization characteristics marked by right and left hemispheres had a normal CT (computerized tomography) scan. (CL)

The author reviews the controversy over definitions of learning disabilities and posits two "givens" in any defintion of the condition: that all learning is neurological, and that learning is conditioning. He proposes a definition based on neuropsychological dysfunction which can be translated into an educational regimen. (CL)

Sixty-two learning disabled children (6 to 19 years old) were subgrouped according to etiology--neurocognitively impaired and neurocognitively intact. The two groups were found to be intellectually different from one another, as the impaired scored much lower on a general intelligence test than the intact. (Author/SB)

The author considers the future of learning disabilities, particularly in relation to mainstreaming, the perceptual deficit hypothesis, and the psychoneurology of learning. (SBH)

Five resistive activities (activities which integrate symmetric tonic neck reflex and facilitate learning) for use with problem learners are briefly described. Reports on using resistive activities with learning disabled children are offered. (SBH)

This paper reviews literature supporting the notion that learning disabilities are presumed to be a result of central nervous system dysfunction. It focuses on the postmortem and neuroimaging studies that provide evidence of a neurological conceptualization of learning disabilities. (Author/JDD)

The paper summarizes several approaches to the identification of learning disability and then discusses the nature of learning disability in the context of competing hypotheses as possible explanations of insufficient or unsatisfactory achievement. Because learning disability may only be inferred as a cause of unsatisfactory learning, the…

Among conclusions of this review of findings regarding contemporary neuropsychology and cerebral hemisphere specialization as related to learning disabilities are: (1) differential specialization occurs very early; (2) anomalous hemispheric specialization is not necessarily associated with cognitive deficit; and (3) left- and right-hemisphere…

Fundamental assumptions concerning the cause of learning disabilities are described and criticized. At a broader level, research and theory in three different paradigms are discussed: (1) neuropsychological; (2) information processing; and (3) applied behavior analysis. Four recommendations for future progress in the conceptualization and…

The use of neurometric techniques for screening of learning disabilities and the subsequent use of electroencephalogram biofeedback techniques provides a solid foundation for helping children with attention deficit disorders to improve markedly their ability to learn and to obtain significant improvements in school performance.

Review of four published cases of aphasia in deaf patients illustrates that loss and recovery of language functions in the deaf follow the pattern noted in hearing patients, and thus the notion of a separate cerebral area for manual speech postulated by Jackson (1878) is not supported. (Author/KW)

The brains of 16 premature infants who died within their first month of life were studied microscopically. Journal Availability: See EC 152 470. (Author/CL)

Comparison of alpha amplitudes of 12 children with learning disabilities and 12 normally achieving controls in three task situations found no significant differences between groups in alpha amplitude but a significant task effect with the vigilance, story comprehension, and rehearsal conditions showing decreasing alpha amplitudes in both groups of…
