CEREBRAL PROCESSING OF SPATIAL AND VERBAL-ANALYTIC TASKS - EEG STUDY

Cerebral processing was investigated as a function of cognitive task and spatial ability. EEGs were recorded while 38 subjects, ages 16-18, performed four tasks. The production requirement of the tasks varied along a spatial-analytic continuum while the perceptual requirement was held constant for three of the tasks and was nil for the fourth. Task related alpha power ratio differences were observed, supporting the hypothesis that hemispheric processing is a function of the task processing demands and not just related to the perceptual requirements. © 1979.
