Does placing females in environments in which they have contact with males cause deficits in their problem-solving performance? Is a situational cue, such as gender composition, sufficient for creating a threatening intellectual environment for females--an environment that elicits performance-impinging stereotypes? Two studies explored these questions. Participants completed a difficult math or verbal test in 3-person groups, each of which included 2 additional people of the same sex as the participant (same-sex condition) or of the opposite sex (minority condition). Female participants in the minority condition experienced performance deficits in the math test only, whereas males performed equally well on the math test in the two conditions. Further investigation showed that females' deficits were proportional to the number of males in their group. Even females who were placed in a mixed-sex majority condition (2 females and 1 male) experienced moderate but significant deficits. Findings are discussed in relation to theories of distinctiveness, stereotype threat, and tokenism.

Stereotype threat research has demonstrated that stereotypes can harm student performance in the face of public evaluation by peers or an experimenter. The current study examined whether stereotypes can also threaten in private settings. Female students completed a math test in 3-person groups, which consisted of either 2 other women (same gender) or 2 men (minority). In addition, students either believed their performance would be broadcasted to their peers (public) or not (private). Results revealed that minority students performed worse than same-gender students in both public and private environments. This finding supports the concept of threatening intellectual environments and shows how far reaching the effects of stereotypes can be. The authors discuss these findings in relation to research on tokenism and to stereotype threat and its educational implications.

Children's interpersonal perceptions in an academic context were studied from the sociocultural perspective (L. S. Vygotsky, 1978). The authors predicted that with development, judgments of classmates would show increasing impact of the stimulus target (consensus) and decreasing impact of the perceiver's effect. A social relations analysis estimated perceiver and target effects. A 3-year cross-sequential design permitted study of age differences and longitudinal consistency of the effects. Children's interpersonal perceptions were consensual in middle childhood, and target effects increased with development, whereas perceiver effects declined. Target effects were more consistent than perceiver effects across a 3-year period. Target effects for behaviorally based and environmentally cued judgments, however, were more consistent than target effects on judgments of psychological characteristics.
