Four physiological conditions associated with later learning disabilities are noted: Turner Syndrome (a chromosomal abnormality), preterm children with intracranial hemorrhage, children with incompletely developed connecting fibers between the cerebral hemispheres, and children with acquired brain injury. (CL)

The authors postulate that dysfunctions in the cortical sensorimotor areas of the brain that control internal speech may adversely affect the learning of reading, writing, spelling, and arithmetic, especially in children who are first learning these skills. (Author)

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)

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…

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…

This article highlights the scientific contributions of nineteenth-century German researchers in describing neuropsychologic dysfunction and in conceptualizing and cerebrally localizing clinical syndromes associated with learning disabilities. Noted are contributions of Pierre Paul Broca, Carl Wernicke, Ludwig Lichtheim, Hugo Karl Liepmann, B.…

This introductory article briefly describes each of the following eight articles in this special issue on the neurology and genetics of learning related disorders. It notes the greater appreciation of learning disability as a set of complex disorders with broad and intricate neurological bases and of the large individual differences in how these…

The article examines neuropsychological theories of behavior and considers their application to special education, with particular emphasis on learning disabilties. Among problems involved with the approach are difficulties communicating educationally relevant data and confusion over the validity and utility of the neuropsychological approach. (CL)

The article is a continuation of a detailed review of the book "The Neuropsychology of Learning Disorders," edited by R. M. Knights and D. J. Bakker. (Author/SBH)

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