We examined whether neural responses associated with judgments of socially relevant aspects of the human face extend to stimuli that acquire their significance through learning in a meaningful interactive context, specifically reciprocal cooperation. During fMRI, subjects made gender judgments on faces of people who had been introduced as fair (cooperators) or unfair (defector) players through repeated play of a sequential Prisoner's Dilemma game. To manipulate moral responsibility, players were introduced as either intentional or nonintentional agents. Our behavioral (likebility ratings and memory performance) as well as our imaging data confirm the saliency of social fairness for human interactions. Relative to neutral faces, faces of intentional cooperators engendered increased activity in left amygdala, bilateral insula, fusiform gyrus, STS, and reward-related areas. Our data indicate that rapid learning regarding the moral status of others is expressed in altered neural activity within a system associated with social cognition.
我们研究了与人类面部社会相关方面判断相关的神经反应是否会扩展到通过在有意义的互动情境（特别是互惠合作）中学习而获得其意义的刺激上。在功能磁共振成像（fMRI）过程中，通过重复进行顺序囚徒困境游戏，受试者对被介绍为公平（合作者）或不公平（背叛者）玩家的人的面部进行性别判断。为了操纵道德责任，将玩家介绍为有意或无意的行为主体。我们的行为（喜好评分和记忆表现）以及成像数据证实了社会公平对人际互动的显著性。相对于中性面孔，有意合作者的面孔在左杏仁核、双侧脑岛、梭状回、颞上沟以及与奖励相关的区域引发了更多活动。我们的数据表明，关于他人道德地位的快速学习表现为与社会认知相关系统内神经活动的改变。
