abstract: National surveys indicate that Americans hold greater prejudice toward atheists than many other historically stigmatized groups. The religious prosociality perspective posits that people will demonstrate prejudice toward anyone who does not believe in a monitoring and punishing god, including atheists, because of the perception that those who lack belief in a monitoring and punishing god cannot be trusted to act in a prosocial manner. The sociofunctional perspective posits that people will demonstrate distinct forms of prejudice toward individuals who present certain types of threats to the group, and previous research suggests that atheists are perceived as posing a threat to group values. In the current study, participants rated targets whose values largely matched their own values more favorably than targets whose values did not largely match their own values. Also, participants rated both targets who believed in a monitoring and punishing god and targets who believed in a god who does not monitor nor punish more favorably than atheist targets. These judgments spanned a variety of measures, including emotional reactions to the target, judgments of target traits, and preferred social distance from the target. Results were consistent with the sociofunctional perspective but did not support the religious prosociality perspective. / Dissertation/Thesis / M.A. Psychology 2013
