Psychological test performance as a function of lateral localization of cerebral lesion.

Abstract

Two batteries of psychological tests, defined as primarily verbal and spatial in character, were administered to 59 hospitalized Ss with lateralized cerebral lesions. The hypothesis that Ss with left hemisphere lesions would show a greater impairment on the verbal battery as compared with right-sided Ss was supported by the data. The hypothesis that right-sided Ss would demonstrate greater impairment on the spatial battery as compared with left sided Ss was not supported. After eliminating dysphasics from the left sided group, there were no significant differences in performance on either battery. However, the two intra-group battery patterns were significantly different.
