Developmental research on moral psychology has long been driven by the classic studies of Lawrence Kohlberg with an almost exclusive focus on reasoning. The adoption of an evolutionary perspective has opened moral psychology to investigations into the deep roots of morality. From this perspective, it is thought that group living (cooperation), evolved psychological mechanisms, disgust, emotion, and punishment make for the complex building blocks that is morality. Based on this notion, it is quite possible that morality is present early in life and driven by the forces of natural selection. Thus, moral development may be understood by taking a different approach, one that takes into account the tenants of evolution. The purpose of this study was to investigate the effects of third-party punishment on children’s moral sentiments using a common moral transgression (exclusion from a group). For this cross-sectional study, children in age groups 4-5, 7-8, and 12-13 years heard two short stories describing a perpetrator (matched in gender to the participant) who excludes a victim (also matched in gender to the participant). For each story, children were asked to imagine a different relationship to the victim: kin (i.e., brother or sister) or non-kin (i.e., friend/stranger). After each story, children were asked to rate the intensity of the moral transgression, choose a possible punishment for the perpetrator, identify an emotion associated with the transgression, and then offer a justification for the emotion. A total of 109 children were interviewed for the study. Results were mixed. Relationship (kin vs. non-kin) made a difference in some cases, while not in others. Overall, all children rated the treatment of the victim as wrong, deemed punishment as necessary, and reported neutral emotions. The children in the 12 to 13 age group were different on measures of wrongness and emotional responses. There is some evidence that relationship may influence moral sentiments, which is in line with an evolutionary hypothesis. Moral sentiments seem to be present early, and common moral transgressions are perceived as wrong early and consistently across age groups. This study provides some insight into the evolutionary roots of morality. Additional research is necessary to gain a greater understanding of other factors contributing to the evolutionary roots of morality. / Includes bibliography. / Dissertation (Ph.D.)--Florida Atlantic University, 2019. / FAU Electronic Theses and Dissertations Collection
