The article provides a brief review of theory and research on the roles of guilt, shame, and sympathy in predicting moral behaviors. Two models are presented and contrasted. The guilt-based model proposes that guilt and shame jointly predict prosocial and aggressive behaviors. In contrast, the sympathy-based model suggests that perspective taking and sympathy are linked to such behaviors. In both models, prosocial moral reasoning is proposed as a possible mediator in these relations. Results from a study of college students suggest support for both models. Moreover, there is evidence that prosocial moral reasoning mediates the relations between these moral emotions and moral behaviors. The implications for the need to incorporate moral emotions and cognitions into existing models of morality are discussed and emphasized. (Contains 2 figures, 1 table and 47 notes.)
