Effects of intergroup exclusion on individual needs threat and behavior tendencies.

Abstract

This study explores the effects of intergroup exclusion on need-threat and the behavioral tendencies of excluded individuals. Results show that those excluded by in-group members perceived more threat to relational needs, while participants excluded by out-group members perceived more threat to efficacy needs. In addition, participants excluded by out-group members displayed significantly more aggression intention and less helping intention than those who were excluded by in-group members. This study indicates that the group relationship between excluders and the excluded will directly affect threat perception and behavioral responses.
