Hemispheric and Frontal Differentiation in Cognitive Processing in the Wechsler Intelligence Tests

Cinamon C. Romers, School of Psychology

Previous research has focused primarily on left hemisphere brain functioning but there is a dearth of information on right hemisphere, cognitive functioning in the literature. The subtests that make up the Perceptual Reasoning Index of the Wechsler scales were administered to a sample of 241 adults and children to determine if any of these tasks, which claim to measure visuospatial constructs thought to be dependent on right posterior parietal brain areas, actually tap into analytic, left posterior parietal and executive frontal functions.
