Sex-role orientation as related to psychological and physiological responses during achievement and orthostatic stress

The Bem sex-role inventory was used to select, from an Irish student population, females and males who differed with regard to feminine and masculine personality characteristics. Four groups were established for each sex: (1) subjects with low scores in both femininity and masculinity, i.e., undifferentiated subjects; (2) subjects with high scores in both femininity and masculinity, i.e., androgynous subjects; (3) subjects with high scores in femininity and low scores in masculinity; (4) subjects with high scores in masculinity and low scores in femininity. The Cattell 16 PF scale showed that the undifferentiated groups were more reserved and detached and more cautious and taciturn than the androgynous groups. Each subject was exposed to mental stress in one session and orthostatic stress in another session. Mental stress was induced by five different intellectual performance tests. Males and females differed significantly only on a test of perceptual speed, with females performing better than males, as expected. The group of androgynous females was superior to all other groups on four of the five performance tasks. The group of androgynous males was not superior in terms of objective performance but reported feeling more confident andThis collaboration was made possible by a twinning grant to Dr. John Cullen and Professor Marianne Frankenhaeuser from the European Training Programme in Brain and Behaviour Research, European Science Foundation. Financial support was also obtained by grants from the Swedish Medical Research Council (Project No. 997) and the Swedish Council for Research in the Humanities and Social Sciences. satisfied with their performance than most other groups, particularly the undifferentiated males. Blood pressure and heart rate were significantly elevated in all groups during both stress conditions. Heart rate was significantly higher in the high-femininity and androgynous females than in the other female groups.
