ABSTRACT: Reasoning about what other people see, know, and want is essential for navigating social life. Yet even neuro-typical adults frequently make perspective-taking errors. Here, we examined how the group membership of perspective-taking targets affects processes underlying level-1 visual perspective-taking. In three experiments using two bases of group identity (i.e., university affiliation and minimal groups), interference from one’s own visual perspective (i.e., egocentric intrusion) was consistently stronger when responding from an ingroup versus an outgroup member’s perspective. However, spontaneous perspective calculation, as indexed by interference from another’s visual perspective when reporting one’s own perspective (i.e., altercentric intrusion), did not differ across target group membership. Process-dissociation analyses that isolate the contribution of automatic processes to altercentric intrusion further revealed negligible effects of group membership. These findings suggest that shared group membership may bias visual perspective-taking by selective impairing the inhibition of one’s own perspective.
