信任是人的感知和人际决策的核心。在两项研究中，我们研究了物理温度作为一个因素，可以影响人类的信任行为，和作为一个可能的神经基板的温度。参与者短暂地触摸一个冷的或热的包，然后玩一个经济信任游戏。与那些触摸温暖包裹的人相比，那些被冷刺激的人对匿名伴侣的投入较少，显示出较少的人际信任。在研究2中，我们使用功能性磁共振成像检查了温度操纵后信任相关过程中的神经活动。只有在做出信任决定之前先触摸冰袋，而不是暖包时，左前岛状区才比基线激活得更强烈。此外，更大的激活双侧小脑延髓在决定阶段，其次是冷操作，对比温暖。这些结果表明，温度可能是一个关键的共享神经基质，介导的信任过程的温度的影响。
Trust lies at the heart of person perception and interpersonal decision making. In two studies, we investigated physical temperature as one factor that can influence human trust behavior, and the insula as a possible neural substrate. Participants briefly touched either a cold or warm pack, and then played an economic trust game. Those primed with cold invested less with an anonymous partner, revealing lesser interpersonal trust, as compared to those who touched a warm pack. In Study 2, we examined neural activity during trust-related processes after a temperature manipulation using functional magnetic resonance imaging. The left-anterior insular region activated more strongly than baseline only when the trust decision was preceded by touching a cold pack, and not a warm pack. In addition, greater activation within bilateral insula was identified during the decision phase followed by a cold manipulation, contrasted to warm. These results suggest that the insula may be a key shared neural substrate that mediates the influence of temperature on trust processes.
