The Process of Group Differentiation in a Dynamic Intergroup Setting

Abstract

The purpose of this study was to examine the social categorization processes of between-group differentiation and within-group similarity in a dynamic intergroup setting. Traditionally, these processes have generally been examined in static settings, and it was hypothesized that they may not operate in the same way when group members are in a dynamic intergroup setting. Spectators at four collegiate hockey games were tested throughout the games in order to examine ingroup (home team) versus outgroup (visiting team) perceptions. The traditional effect of ingroup favoritism was found with respect to between-group differentiation, but this effect was influenced by objective measures of performance (i.e., goals). For negative characteristics, ingroup favoritism prevailed regardless of the ingroup's relative performance. The results also demonstrated that a distinction could be made between ingroup favoritism and outgroup discrimination. Although the results pertaining to within-group similarity were only suggestive, they indicated that the outgroup homogeneity effect was not operating in this dynamic context.
