Researchers at Indiana University have published a study offering additional evidence that stereotype threat has the potential to hurt women's performance in math.
Participants in the study—133 women and 101 men, all in college—watched a short video showing actors forming a study group. Each video featured either a dominant man, a dominant woman, or group dynamics in which neither gender dominated. After they watched the video, the subjects were given 20 minutes to solve 30 math problems.
The women who watched the video in which a male dominated the formation of a math study group performed worse on the test than women who watched other videos.
