Neuropsychological comparisons of normal, learning disabled and brain damaged children ages five through thirteen
This report is oriented at defining characteristics of children who have problems with school-related skills and abilities (Learning Disabled, N=17) as compared with Brain Damaged children (N=17) and Normals (N=17) as measured by selected measures of the Halstead-Reitan Neuropsychological Test Battery. Also, the Wechsler Intelligence Scale for Children (WISC) and the Wide Range Achievement Test (WRAT) were given to each subject. Subjects were matched for age, sex, and Full Scale Intelligence Quotient as measured by the WISC.It was found that Control children differed significantly on neuropsychological measures when compared to Brain Damaged children. There were no significant differences on the WISC or WRAT. The Learning Disabled children resembled the Brain Damaged children more than they resembled the Control children on several of the neuropsychological measures. No significant lateralized deficits on motor or sensory-motor tasks were found to differentiate between the HV-LP and the LV-HP groups with respect to consistent lateralized deficits on the motor, perceptualmotor, or sensory measures, although both groups were significantly poorer than Controls on some of the sensory measures, particularly perception. of numbers written on the fingertips.
