Group-based emotions have been conceptualised as being rooted in perceivers' social identity. Consistent with this idea, previous research has shown that social identity salience affects group-based emotions, but no research to date has directly examined the role of group-based appraisals in comparison with individual appraisals. In the present studies, we measured group-based appraisals through a thought-listing procedure. In Experiment 1, we explicitly reminded people of their group identity, which led to the predicted change in group-based anger. This effect was mediated (...) by group-based appraisals. In Experiment 2, participants either discussed a group-relevant scenario in small groups or a related topic irrelevant to the group. The group-relevant condition not only led to stronger indignation but the perceived presence of group-based appraisals was also related to participants' reports of indignation. These results provide further evidence for the importance of group-based appraisals as components of group-based emotions. (shrink)
