According to the theory of stereotype threat (C. M. Steele, 1997; C. M. Ste
ele & J. Aronson, 1995), activating stereotypes about a group's typical und
erperformance on a task can undermine a group member's performance on that
task. The goal of the present research was to more fully delineate the cont
exts that activate task-performance stereotypes and the mechanisms that mig
ht lead to, or potentially prevent, such performance decrements. In 2 exper
iments, individuals led to believe that they had high ability on a task pre
dicted that they would do better on future performances of the same or simi
lar tasks than did those given ambiguous feedback about their task abilitie
s when stereotypes were not accessible. However, activating group stereotyp
es-for instance, by creating expected solo status-undermined these positive
expectations.
