Cooperation between individuals requires the ability to infer eachother’s mental states to form shared expectations over mutualgains and make cooperative choices that realize these gains. Fromevidence that the ability for mental state attribution involves theuse of prefrontal cortex, we hypothesize that this area is involvedin integrating theory-of-mind processing with cooperative actions.We report data from a functional MRI experiment designed to testthis hypothesis. Subjects in a scanner played standard two-person‘‘trust and reciprocity’’ games with both human and computercounterparts for cash rewards. Behavioral data shows that sevensubjects consistently attempted cooperation with their humancounterpart. Within this group prefrontal regions are more activewhen subjects are playing a human than when they are playing acomputer following a fixed and known probabilistic strategy.Within the group of five noncooperators, there are no significantdifferences in prefrontal activation between computer and humanconditions.
