Although altruistic and selfish behaviors seem fundamentally incommensurate, humans regularly choose between them. One model of such choices suggests that individuals ascribe a common form of subjective value to their own outcomes and those of others. To test this person invariance hypothesis, we asked individuals to choose between allocating varying amounts of money to themselves or to a partner. Participants' choice patterns provided an estimate of the relative value they placed on their own and others' gains. These estimates were used to isolate neural activity correlating with the subjective value of gains irrespective of the recipient (self or other) during a separate set of trials in which rewards were offered only to the self or partner. Activity in ventromedial prefrontal cortex scaled with this person-invariant value parameter, consistent with earlier demonstrations that this region supports common value computation. These data suggest that individuals reduce the value associated with their own and others' experiences to a common subjective scale, which is used to guide social decision-making.
