Anti-black prejudice as a function of exposure to the negative behavior of a single black person.

The authors examined whether the negative behavior of 1 Black male would influence White participants' perceptions of Black Americans and behavior toward another Black person. In Study 1, it was found that participants in the Black-negative condition tended to stereotype Blacks more than participants in the Black-control condition did. It was also found that participants who had observed a negative behavior, whether it was performed by a Black or a White confederate, avoided a subsequently encountered Black person more often than did participants in either the positive condition or the control condition. In a 2nd study, interpersonal interactions with a Black person were minimized only after participants observed the negative behavior of a Black confederate. Study 3 extended the findings of Study 1 by showing that group level stereotypes and the expression of ingroup favoritism resulted from simply overhearing a conversation in which a Black person was alleged to have committed a crime.
