Activity in the amygdala elicited by unfair divisions predicts social value orientation

Abstract

'Social value orientation' characterizes individual differences in anchoring attitudes toward the division of resources. Here, by contrasting people with prosocial and individualistic orientations using functional magnetic resonance imaging, we demonstrate that degree of inequity aversion in prosocials is predictable from amygdala activity and unaffected by cognitive load. This result suggests that automatic emotional processing in the amygdala lies at the core of prosocial value orientation.
