社会责任将个人行为与社会期望联系起来，并在影响决策后代理人的情绪状态方面发挥关键作用。然而，责任归因的神经基础仍然不清楚。在之前的两项事件相关脑电位（ERP）研究中，我们发现个人责任感调节了赌博任务的结果评估。在这里，我们进行了一项功能性磁共振成像（fMRI）研究，以确定特定的大脑区域，介导的责任归属。在涉及团队合作的背景下，参与者与他们的队友完成了一项任务，并在每次试验中依次收到关于团队成功和个人成功的反馈。我们发现，在团队成功和团队失败的情况下，大脑活动是不同的。此外，不同的大脑区域与社会表扬与金钱奖励的行为强化有关。具体来说，右颞顶连接（RTPJ）与社会自豪感，而背侧纹状体和背侧前扣带皮层（ACC）与强化行为，导致个人收益。本研究提供的证据表明，RTPJ是一个重要的区域，以确定是否自我产生的行为是值得赞扬的社会背景下。
Social responsibility links personal behavior with societal expectations and plays a key role in affecting an agent’s emotional state following a decision. However, the neural basis of responsibility attribution remains unclear. In two previous event-related brain potential (ERP) studies we found that personal responsibility modulated outcome evaluation in gambling tasks. Here we conducted a functional magnetic resonance imaging (fMRI) study to identify particular brain regions that mediate responsibility attribution. In a context involving team cooperation, participants completed a task with their teammates and on each trial received feedback about team success and individual success sequentially. We found that brain activity differed between conditions involving team success vs. team failure. Further, different brain regions were associated with reinforcement of behavior by social praise vs. monetary reward. Specifically, right temporoparietal junction (RTPJ) was associated with social pride whereas dorsal striatum and dorsal anterior cingulate cortex (ACC) were related to reinforcement of behaviors leading to personal gain. The present study provides evidence that the RTPJ is an important region for determining whether self-generated behaviors are deserving of praise in a social context.
