Elliott, Digby; And Others – American Journal of Mental Retardation, 1987
The review examined recent research concerning cerebral specialization, especially dichotic listening studies, in Down syndrome individuals. A model of cerebral specialization is proposed that stresses the biological dissociation between speech perception and speech production or other complex movements. (Author/DB)

Cook, Edwin H., Jr. – Journal of Autism and Developmental Disorders, 1996
This paper reviews what is known about the role of neurochemicals in controlling the development of the brain and in the pathophysiology of autism. Suggested approaches to further research involve using animal models, examining effects of drugs on neurochemicals, and using such technologies as positron emission tomography and magnetic resonance…

Small, Steven L. – Journal of Communication Disorders, 1994
Connectionist (parallel distributed processing) modeling provides a new way to approach the neurological study of language. This method focuses on the interplay between a computational model and the appropriate neurological, neuropsychological, and speech and language data, couched in connectionist mechanisms that map naturally to what is known of…

Denckla, Martha Bridge – Annals of Dyslexia, 1987
This paper examines the influence of Norman Geschwind's model of connectionism, in which complex functions are built up by connecting primary areas in the brain, and notes his studies of the effects of disconnection on dyslexic individuals. Connectionist-based behavioral studies are reviewed, focusing on intracortical association connections and…

Bachevalier, Jocelyne – Journal of Autism and Developmental Disorders, 1996
Research on humans and monkeys is reviewed that supports the view that the medial temporal lobe, and, perhaps more specifically the amygdala, is the neural substrate underlying social deficits in autism. The relationship of early medial temporal lobe lesions to memory and socioemotional behavior is reviewed, as are the roles of the amygdala and…

Swanson, H. Lee – Journal of Learning Disabilities, 1988
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…

Languis, Marlin; Naour, Paul – 1985
For the individual, gender difference falls along the feminine-masculine continuum with strong neurodevelopmental influences at various points throughout the lifespan. Neurodevelopmental influences are conceptualized in a vector model of sex difference. Vector attributes, direction and magnitude, are influenced initially by differences in levels…
