In order to increase the knowledge of locomotor disturbances in children with autism, and of the mechanism underlying them, the objective of this exploratory study was to reliably and quantitatively evaluate linear gait parameters (spatio-temporal and kinematic parameters), upper body kinematic parameters, walk orientation and smoothness using an…

This study examined whether children with mathematical difficulties (MDs) or comorbid mathematical and reading difficulties have a working memory deficit and whether the hypothesized working memory deficit includes the whole working memory system or only specific components. In the study, 31 10-year-olds with MDs and 37 10-year-olds with both…

This article reviews various models in the neurological conceptualization of attention deficit disorder (ADD), with and without hyperactivity. It discusses neuroanatomical, neurochemical, and neurophysiological perspectives on ADD. (Author/DB)

Two studies of a visual-motor tracking task purported to effectively discriminate subtypes of minimal brain dysfunction are presented. Subjects were psychiatric inpatients, hyperactive males, and normal controls. The tracking task was found to be a useful measure of stimulant drug action but not of specific hyperkinetic defects.

This document describes the present federal effort on behalf of learning disabled children, beginning with its recent history. It traces the field of learning disabilities as a subspecialty within education from 1963, when a steering committee was appointed to organize a symposium on "The Child with Minimal Brain Dysfunction," through the Learning…

Research suggests that children with specific language impairment (SLI) have processing limitations; however, the mechanisms involved have not been well defined or investigated in a theory-guided manner. The theory of constructive operators was used as a framework to explore processes underlying limited processing capacity in children with SLI.…

Investigated in the first of two studies on verbal elaboration in special populations (learning problem and retarded children) were the effects of paragraph elaboration on the paired-associate and reversal learning of 137 brain-injured and familial educable mentally retarded children 8- to 13-years-old. The relationship between brain-injury…
