When stereotype-based expectancies impair performance: The effect of prejudice, race, and target quality on judgments and perceiver performance

High- and low-prejudiced participants were presented with a lecture segment in which the race of the professor (White or Black) and lecture quality (h igh or low) were manipulated. Consistent with predictions, low-prejudiced p articipants were more extreme in their evaluations (more negative) and perf ormed more poor ly on test items when presented with an expectancy-violatin g low-quality Black lecturer. High-prejudiced participants were more extrem e in their evaluations (more positive) and performed more poorly when prese nted with an expectancy-violating high-quality Black lecturer.
