This research examined the effects of Personal Need for Structure, Need for Closure, and Personal Fear of Invalidity on information processing during the development of stereotypes. In Study 1, participants read as many group member descriptions as they wanted before expressing group stereotypes. Participants higher in Personal Fear of Invalidity sought more information; they also developed more detailed stereotypes when they received more information, whereas participants lower in Personal Fear of Invalidity did not. There was a tendency for participants higher in Need for Structure & Closure to develop less accurate stereotypes. Finally, participants higher in Need for Structure & Closure or Personal Fear of Invalidity were less confident about their stereotypes when they received more information, whereas participants lower in Need for Structure & Closure or Personal Fear of Invalidity were more confident. In Study 2, participants were presented with two, four, or eight descriptions of group members before expressing stereotypes. Participants lower in Personal Fear of Invalidity developed more detailed stereotypes when they received more information, whereas participants higher in Personal Fear of Invalidity did not. When two or eight group member descriptions were presented (fewer or more than participants probably would have chosen themselves), participants higher in Personal Fear of Invalidity and lower in Need for Structure & Closure generated the most accurate stereotypes. Finally, participants higher in Need for Structure & Closure did not differ in stereotype confidence as a function of how much information they received, whereas participants lower in Need for Structure & Closure were more confident when they received more information. These results indicate that cognitive style plays a role in the development of group stereotypes.
