| Abstract: | Eight hyperactive children were compared to eight control children matched with regard to age, ethnicity and school grade on tests of auditory perception and memory (Digit Span), spatial figure recognition (Gestalt Closure Speed Test), and perceptual/cognitve style (Children's Embedded Figures Test). It was found that hyperactive children were significantly lower (p < .005) than control children on the auditory perception and memory variable but not on the spatial figure recognition task (p < .77) nor on the perceptual/cognitive style task. The data suggest that hyperactive children are deficient on tasks requiring sequential scanning patterns and involving left cerebral hemisphere functioning but not on tasks involving the right hemisphere, or where sequential scanning patterns are not essential. |
