Following the social role theory (SRT: Eagly & Steffen, 1984), gender-stereotypic beliefs stem from the observation of women and men in different social roles that require different types of traits. In four experiments (485 participants altogether) we addressed the question of whether language production reflects and reproduces gender stereotypes. Participants created person descriptions in which they could refer to gender (e.g., women/men, he/she) and/or occupational roles (e.g., nurses/police officers) with either communal or agentic traits (e.g., caring or assertive). In Experiment 1, participants more often combined female pronouns to female-typical occupational roles, and male pronouns to male-typical occupational roles. In Experiment 2 and 3, persons in female-typical occupations were more likely ascribed with communal traits, whereas persons in male-typical occupations were more likely ascribed with agentic traits. In both experiments, occupational roles had a stronger influence on trait ascriptions than sex definitional nouns/pronouns. Experiment 4 provided the critical test of social role theory revealing that trait ascriptions did not differ when women and men where described in the same occupational role.
