Abstract

Perception–action-coupling refers to the vicarious activation of the neural system for action during perception of action, and is considered important for forms of interpersonal sensitivity, including empathy. We hypothesize that perception–action-coupling is limited to the ingroup: neural motor networks will fire upon the perception of action, but only when the object–person belongs to the ingroup; if the object–person belongs to an outgroup these motor neurons will not fire. Using electroencephalographic oscillations as an index of perception–action-coupling, we found exactly this: participants displayed activity over motor cortex when acting and when observing ingroups act, but not when observing outgroups – an effect magnified by prejudice and for disliked groups (South-Asians, then Blacks, followed by East Asians). These findings provide evidence from brain activity for yet another detrimental aspect of prejudice: a spontaneous and implicit simulation of others’ action states may be limited to close others and, without active effort, may not be available for outgroups.
