This article investigates the influence of two perceived membership-group characteristics (history and value homogeneity) on levels of attributional confidence and deindividuation of group members; on two interaction strategies, interrogation and self-disclosure; and on the likelihood of personal-level and group-level communication about current events. A completely crossed, two-factor, within-subjects experimental design was developed for this study. Perceived group history and perceived group value homogeneity were both manipulated variables. Homogeneity was positively related to attributional confidence, deindividuation, interrogation, and self-disclosure, whereas history was positively related to attributional confidence. The study indicates that perceived group value homogeneity eases the process of intragroup interaction and that perceived group history also positively influences intragroup processes, although perhaps more indirectly and to a lesser degree than does group homogeneity. Implications for public communication campaigns that aim to increase personal involvement in public and community affairs or to tap social / cultural identity as a first step in changing socially undesirable behaviors are discussed in light of these results.
