Sensorimotor Functions, Intelligence and Cognition, and Emotional Status in Subjects with Cerebral Lesions

Abstract

Ss with traumatic, neoplastic, or vascular cerebral lesions composed two groups, one with sensorimotor functions which were relatively intact and the other with functions which were relatively impaired. This basis for selection resulted in an intact group that was somewhat younger, had a somewhat higher education, and had a higher proportion of patients with traumatic brain lesions. The group with impaired sensorimotor functions had a disproportionately higher number of Ss with cerebrovascular lesions. The groups were compared on various measures of intellectual and cognitive functions and on the MMPI. The results indicated that impairment of sensorimotor functions had a strong relationship to intellectual and cognitive measurements, with the impaired group being greatly inferior to the group with relatively intact sensorimotor functions. An influence in the same direction was noted on the MMPI variables, but the intergroup differences were not as great.
