Examined the effects of increased occupational participation by women. 114 male and 86 female undergraduates were led to believe that 5 high-status professions would include increasing proportions of female practitioners. Ratings of occupational prestige and desirability decreased when Ss anticipated increased proportions of women in 4 of 5 professions, and the decrease did not differ for ratings by male and female Ss. Ratings on adjective pairs taken from the semantic differential suggest that reductions in prestige and desirability were accompanied by attributions of increased passiveness, insecurity, and uselessness, and decreased success to occupations admitting more women.
