Can Peripheral Group Members Not Represent the In-Group? The Effect of Member Prototypicality on Intergroup Conflict

Group member prototypicality is a factor in intergroup conflict-not all group members fight for group interests. This study focuses on the role of peripheral group members and the factors that influence their participation. We conducted two studies to examine the effects of group acceptance and self-uncertainty on the relationship between prototypicality and intergroup conflict. Results indicate that group acceptance moderates the relationship between prototypicality and intergroup conflict. Self-uncertainty moderates the effect of the interaction between prototypicality and group acceptance on intergroup conflict. Our findings have theoretical and practical implications for intergroup conflict resolution.

National identity exploration attenuates the identification–prejudice link

Social identity exploration is a process whereby individuals actively seek information about their group membership and show efforts to understand its meaning. Developmental theory argues that exploration-based ingroup commitment is the basis for outgroup positivity. We tested this notion in relation to national identity and attitudes towards immigrants. The results of five experimental studies among German adolescents and early adults ( N = 1,146; 16–25 years) and one internal meta-analysis suggest that the positive identification–prejudice link is weaker when participants are instructed to explore the meaning of their identity (Study 1). This is not mediated via self-uncertainty (Study 2), but via a reduction in intergroup threat (Study 3) and an increase in deprovincialization (Study 4). In addition, identity exploration enabled strong identifiers to oppose descriptive ingroup norms (Study 5). We conclude that identity exploration can contribute to a further understanding of the identification–prejudice link.

Religious fundamentalism is associated with hyperactive performance monitoring: ERP evidence from correct and erroneous responses

The aim of the current study was to examine whether action monitoring is associated with religious fundamentalism. Participants performed a stop-signal task that required response inhibition to a simple auditory tone. The level of their religious fundamentalism was measured on a scale. Analysis with mixed-effects linear models revealed significantly larger error-related negativity, correct-related negativity, and post-error positivity components in individuals scoring higher on religious fundamentalism, pointing to their increased engagement in response monitoring. However, it was not accompanied by improved behavioral performance. The electrophysiological results of our study suggest that individuals high in religious fundamentalism engage more in monitoring for conflict between outcomes of their actions and standards of correct behavior. Our findings also point to a possible association between a fundamentalist mindset and higher levels of negative affect, uncertainty, anxiety, and distress, as measured by response-related brain activity.

Retaliation against the outgroup: The role of self-uncertainty

Outgroups who threaten the core aspects of one’s identity, such as one’s social group and its values, may make group members feel self-uncertain. Because past research associates uncertainty with defensive behavior, we propose that self-uncertainty will drive aggressive retaliation against a threatening outgroup. Two experiments tested the role of self-uncertainty in retaliation motivation. In Experiment 1, university students were threatened by their school rival and then reported self-uncertainty and willingness to retaliate. The threat evoked anger and caused male group members to feel significantly more self-uncertain, which was associated with significantly greater retaliation motivation. In Experiment 2, we manipulated Americans’ feelings of self-uncertainty and threat from a terrorist group, ISIS. Uncertain males were significantly more willing to retaliate against ISIS after threats that caused anger and fear. For male group members, outgroup threat increases self-uncertainty, which then motivates them to be more willing to violently retaliate.
