This study examined whether the degree to which one perceives overlap between the self and another person predicts the magnitude of the neural response of the anterior cingulate cortex (ACC) following the observation of that person's errors. Specifically, we measured the magnitude of the observational feedback-related negativity (oFRN), an event-related potential associated with observing someone else make an error, while participants watched strangers or friends complete a Stroop task. Results show stronger activation of the ACC, as indexed by the oFRN, for those who observed friends compared to those who observed strangers. This effect was mediated by the degree to which participants included the other in their conception of the self. This study contributes a unique examination of real-life close pairs to a growing body of research showing that social factors can greatly impact neural processing. (C) 2009 Elsevier Inc.
