在复杂的社交互动中取得成功的最有效方法之一就是读懂同伴的想法并领先他们一步。为了评估在社交紧张的人际关系中对相互读心的神经反应，我们使用 3-T 扫描仪对 16 名参加吃鸡游戏的健康受试者进行了事件相关的功能磁共振成像研究。统计参数映射显示，对应效应（人类减去计算机）专门激活了对应于前副扣带皮层（PCC）的内侧额叶区域和邻近后颞上沟（STS）的边缘上回。此外，当我们分析数据以评估受试者是否做出了风险/攻击性或安全/和解选择时，后验 STS 表明，无论风险或安全决策，对应的决策都具有可靠的效果。相比之下，前 PCC 中揭示了显着的对手 x 选择相互作用。根据我们的研究结果，可以推断后 STS 和前 PCC 在心智化中发挥着不同的作用；前者是心理化的一般机制，而后者则专门参与有社会风险的决策。 (c) 2006 Elsevier Inc. 保留所有权利。
One of the most powerful ways of succeeding in complex social interactions is to read the minds of companions and stay a step ahead of them. In order to assess neural responses to reciprocal mind reading in socially strained human relationships, we used a 3-T scanner to perform an event-related functional magnetic resonance imaging study in 16 healthy subjects who participated in the game of Chicken. Statistical parametric mapping showed that the counterpart effect (human minus computer) exclusively activated the medial frontal area corresponding to the anterior paracingulate cortex (PCC) and the supramarginal gyrus neighboring the posterior superior temporal sulcus (STS). Furthermore, when we analyzed the data to evaluate whether the subjects made risky/aggressive or safe/reconciliatory choices, the posterior STS showed that the counterpart had a reliable effect regardless of risky or safe decisions. In contrast, a significant opponent x selection interaction was revealed in the anterior PCC. Based on our findings, it could be inferred that the posterior STS and the anterior PCC play differential roles in mentalizing; the former serves as a general mechanism for mentalizing, while the latter is exclusively involved in socially risky decisions.
