Positron brain imaging--normal patterns and asymmetries

Regional brain physiology was investigated in 11 normal resting right-handed subjects using positron emission tomography. Cerebral blood flow was studied in all subjects. Cerebral oxygen metabolism was studied in six subjects, and cerebral glucose metabolism was also studied in one subject. In five subjects, physiological activity was higher in left frontotemporal regions than right. These findings may be related to structural cerebral asymmetries or to activation of brain language centers.     

Perceptions of Major Roles by College Students

This study concerns women's and men's perceptions of five roles and role combinations: worker, spouse, parent, worker-spouse, and worker-parent. Undergraduates wrote stories to relevant projective cues. A variation of the Thematic Apperception Test was used. Protocols were coded for degree of (a) conflict, (b) positive outcome, and (c) positive affect, with inter-rater agreement at least 77% for each category. Sex and role differences were analyzed. Results indicate minimal sex differences. The tentative nature of the results is stressed.
