Abstract Details

2019, Doctor of Philosophy, Miami University, Psychology.
Three studies examined the possible impact of social exclusion on dementalization, a possible moderator of this hypothesized relation, and its possible downstream consequence on aggressive behavior. In a Pilot Study, participants were included or excluded by co-players they knew were computer avatars and then rated how much mind they perceived in one of those co-players. Excluded participants ascribed the co-player less mind than did included participants, providing preliminary support for the hypothesis that exclusion triggers dementalization. Study 1 examined a possible boundary condition for this effect, determining whether the exclusion-dementalization link holds for novel “bystander” targets or is specific to perpetrators. Results replicated for perpetrator targets but did not seem to extend to novel bystanders. In Study 2, I examined whether dementalization is one mechanism that can explain why exclusion often triggers aggressive behavior. Contrary to my prediction, I failed to find evidence that dementalization is a catalyst for aggressive behavior following exclusion. Across three studies, I found supportive evidence that exclusion prompts dementalization of perpetrator targets. However, based on the results of the later studies, this effect appears unique to perpetrators and cannot account for the exclusion-aggression link.
