Personality dimensions of Psychoticism (P), Extraversion (E) and Neuroticism (N) were related to multiple measures of lateralized hemispheric processing in order to test the predictions of right hemisphere overactivation in E, right hemisphere underactivation in N, and left hemisphere under- activation/overactivation in P. It was also predicted that architecture students would be characterized by right hemisphere activation and language students by left hemisphere activation. Lateral eye movements, verbal and nonverbal dichotic listening tasks, and Block Design and Digit Span subtests of the WAIS were assessed in 43 undergraduates, together with personality and degree course. High P scores were characterized by fewer rightward eye movements and hence reduced left hemisphere activation, while high N scores were characterized by poorer Block Design and superior Digit Span performance. These results which indicate a relationship between Psychoticism and left hemisphere underactivation are in conflict with the finding of Raine and Manders (1988) ( Br. J. Clin. Pschol . In press) overactivation in those with high schizoid personality scores, a discrepancy which may be resolved by the notion that P reflects a different form of psychosis-proneness to other schizoid scales. |
