Moral Impression Management: Evaluation by an In-Group Member During a Moral IAT Affects Perceptual Attention and Conflict and Response Monitoring

Abstract

Previous research revealed that emphasizing morality increases motivational processes that improve people’s task performance. Here we examined whether this emphasis differentially affects people’s performance in the presence of an in-group compared to an out-group member. Ostensibly while being evaluated by another person, participants performed an Implicit Association Test that was framed as a test of either their morality or their competence. Results showed a smaller bias toward Muslim women in the morality compared to the competence condition, but this effect was more pronounced when participants were evaluated by a member of their minimal in-group. Moreover, in that same condition, event-related potentials revealed increased perceptual attention (N1) and affected conflict and response monitoring (N450 and error-related negativity). These findings suggest that being moral is especially important when monitored by the in-group and reveal the cognitive processes associated with controlling intergroup bias in a social situation.
