【摘要】：信任是指个体在缺乏足够信息来判断他人动机、意图和行为的情况下,将社会资源交给对方处置并承担相应风险的意愿。作为一种基本的社会信号机制,信任对于发展和维持良好社会关系具有重要作用。借助信任博弈范式,研究者揭示了人际信任的认知神经机制并建构了多种理论,包括背叛厌恶理论、社会规范理论、道德规范理论和默认行为模型。脑成像研究发现信任行为主要涉及内侧前额叶、尾状核、杏仁核和脑岛等脑区,其中内侧前额叶主要参与心理推理、情绪认知与调控等过程,尾状核参与同伴值得信赖性的习得与编码,杏仁核和脑岛则主要参与风险、不确定性和背叛恐惧加工。今后研究应侧重不同理论之间的补充与整合,强化不同脑区之间的功能连接与整体性,并注重信任行为中的个体差异。
[Abstract]:Trust refers to the willingness of individuals to give social resources to the other party to deal with and bear the corresponding risks in the absence of sufficient information to judge the motivation intention and behavior of others. As a basic social signaling mechanism. Trust plays an important role in the development and maintenance of good social relations. With the help of trust game paradigm, researchers reveal the cognitive neural mechanism of interpersonal trust and construct a variety of theories, including the theory of betrayal and disgust. Social norms theory, moral norms theory and default behavior model. Brain imaging studies found that trust behavior mainly involves the medial prefrontal lobe, caudate nucleus, amygdala and the brain island and other brain regions. The medial prefrontal lobe is mainly involved in mental reasoning emotional cognition and regulation the caudate nucleus is involved in the acquisition and coding of peer trustworthiness while the amygdala and the brain island are mainly involved in the risk. In the future research should focus on the supplement and integration of different theories strengthen the functional connection and integrity between different brain regions and pay attention to individual differences in trust behavior.

【正文快照】： 人类社会的特殊性在于信任贯穿于所有的人际互动。信任本身是一种悖论现象,同时包含了崇高的抱负与深切的恐惧(Simpson,2007)。一方面,作为一种重要的社会信号机制,信任是建立良好社会关系的基石,它能够降低社会交易成本,易化合作行为,促进社会经济的繁荣发展。诺贝尔奖得主Ar
