Conducted 2 studies with 44 male and female and 115 white male undergraduates to (a) define racial and occupational stereotypes, and (b) investigate the determinants of attribution of these stereotypes. The occupational stereotype was both stronger and more differentiated than the racial, although "pure" cross-validated stereotypes were obtained. The attribution of both stereotypes to complex stimulus persons varying factorially on the dimensions of race (black, white); occupation (professional, working class); social background (professional father, working-class father); and social behavior (assimilation, aggression, and withdrawal as responses to social rejection) was found to depend primarily on factors implying long-term behavioral dispositions, e.g., occupation or social mobility rather than race. Prejudice did not influence this relationship, which was replicated over 2 scale types. (37 ref.) (PsycINFO Database Record (c) 2016 APA, all rights reserved)
