Converging evidence suggests that both emotional and cognitive processes are critically involved in moral judgment, and may be mediated by discrete parts of the prefrontal cortex. Here, we investigated the mediatory effect of right frontopolar cortex (rFPC) on how emotions effected moral judgments. Six adult rFPC damaged patients and 10 healthy controls were included in this study. Participants made judgements on moral dilemmas after being shown either neutral or emotional pictures. The role of rFPC in executive control and emotional experience was also examined. We showed that inducing an emotional state increased the number of utilitarian responses in both patients and controls. However, there were no significant differences between patients and controls in response time or the number of utilitarian responses. Also, no significant between-group differences were observed in personal and impersonal dilemmas prior to, and following emotion induction. Results from the executive control tasks showed reduced performance in rFPC damaged patients compared to controls. The results from this study suggest that rFPC might not have a direct role in mediating emotional processes during moral judgment but possibly this region is important in a network supporting executive control functions.
