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)

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)

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

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…

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…

In response to a previous paper (EC 212 858) regarding the neurodevelopmental evidence for the basis of dyslexia, this paper offers corroborating evidence of neurological difference in dyslexic persons and stresses the need for more research on brain mechanisms in disorders of reading. (DB)

This brief introduction to E. Jan Kappers' article "Outpatient Treatment of Dyslexia through Stimulation of the Cerebral Hemispheres" reviews the lifetime work of Kappers in the field of dyslexia. (CR)

In contrast to the hypothesis that dyslexics possess phonological deficits of neurological origin, the paper proposes that the source of the deficit is primarily experiential. Evidence from normal reading and spelling development as well as from comparisons of dyslexic and nondyslexic readers is offered. (Author/DB)

Historical and present-day ideas concerning recovery of higher brain functions and cognitive retraining after traumatic brain injury are considered. Clinical guidelines for helping patients understand and compensate for residual higher cerebral deficits are suggested. A holistic- or milieu-oriented program is considered the most helpful…

In response to a previous paper (EC 212 858) regarding the neurodevelopmental evidence for the basis of dyslexia, this paper suggests further concerns in the areas of cognitive measurement, the relationship between cortical-functional organization and child development, and lack of operational definitions in the study of the dyslexic syndrome. (DB)

In response to articles concerning the author's earlier paper, the paper responds to criticisms concerning contextualism, the role of metatheory, distinctions between basic and applied research, cognitive components and specificity, the science of learning disabilities, neurological indices, model validation, and the nature of learning…

This report by a Dutch national committee addresses the definition of dyslexia; characteristic symptoms; consequences of the proposed definition for identification and treatment; appropriate methods of treatment; involvement of various professionals (e.g., neuropsychologist, remedial teacher, speech and language therapist, and neurologist); and…
