(A) Differential sensitivity to reward in social and non-social contexts was observed in the ventral striatum during the presentation of outcome, with higher activity following high-reward outcomes relative to low-reward outcomes (P_{(FWE, whole brain correction)} < 0.05, peak voxel coordinates: 9, 11, −11). (B) Beta weights of GROUP × OUTCOME interaction at peak voxel within an anatomically-defined region of interest including caudate, putamen, and globus pallidus (P_{(FWE, svc)} < 0.05, peak voxel coordinates: 12, 5, −17). A significant two-way interaction revealed that individuals who were more risk averse in non-social contexts (−SRS) exhibited greater striatal activity following non-social outcomes, individuals that were more risk averse in the social contexts (+SRS) showed greater striatal activity following social outcomes.
