摘要

人们对于面孔的判断对于社会生存具有重要作用。在当代多元化的社会中,信任在人与人之间的交往中扮演着重要角色,而面孔在其中起着关键的作用。因而对于面孔可信度与信任行为关系的研究能够让我们深入了解其信任行为的依据和原理。信任博弈在前人的研究中,信任方做出的行为决策的差异已经被证明,即信任方在给可信面孔的金额要高于不可信面孔的金额。本研究通过单次多张面孔的信任博弈游戏,并且引入收益率这一自变量;使用功能性近红外成像(fNIRS)探索其投钱行为在前额叶的激活差异表现,同时加入go/no go行为测验和信任问卷,得出她们与信任博弈游戏行为和脑激活程度的相关。结果发现:(1)与以往研究一样,被试作为信任方对可信面孔和不可信面孔的投钱数有显著差异;(2)被试在信任博弈行为中,面孔可信度和收益率在投钱行为上差异显著的脑区在dlpfc(背外侧前额叶皮层),具体位于布鲁德曼9区和布鲁德曼46区,印证了该区域认知调控策略;(3)在引入收益率这一因素和面孔可信度的2*2水平中,脑区激活量和行为的相关也得到了对应,例如,在低可信度6块钱选择投钱的情况下被试的脑区dlpfc(背外侧前额叶皮层具体位于布鲁德曼9区和布鲁德曼46区)相关显著,说明了在做出投钱行为时相应的脑区活动;(4)通过对go/no go和信任问卷分别与脑区激活程度的相关得出同样在dlpfc也是相关显著的结果(行为的测验结果分数越高代表信任倾向越偏向信任他人),行为测验的分数越高,位于dlpfc的投钱行为的大脑激活程度也就越高。
To face the judgment of the survival plays an important role in society.In contemporary society with the traits of pluralism, trust plays an important role in interpersonal communication, and face play a key role in it.So research about the relation between face credibility and trust behavior can make us deeply understand the basis and principle of its trust behavior.Trust game in the previous study, the decision-making differences of truster to make have been shown, that the high trustworthiness face more popular than low trustworthiness face in this game.This study through more than a single face trust game, and introduce the rate of benefits as the independent variable;Using functional near infrared imaging(f NIRS) to explore the differences between in the activation of prefrontal about money, at the same time to join the go/no go behavior questionnaire test and trust questionnaire and trust game behavior and the associated with the degree of brain activation.The results showed:(1) same as the previous research, when the subjects as a truster face on the trusted and untrusted cast money has significant difference;(2) the participants in the act of trust game, faces a credibility and the rate of benefits significant difference on money behavior of brain regions in DLPFC(dorsolateral prefrontal cortex), specific in bloom DE man 9 and bloom DE man 46, confirms the area of cognitive control strategy;(3) at the level of 2 * 2 with yields and faces credibility, brain regions activated related also obtained the corresponding quantity and behaviour, for example, in 6yuan a low credibility to choose subjects of brain regions under the condition of money DLPFC(the dorsolateral prefrontal cortex Specific in bloom DE man 9 and bloom DE man 46) related significantly, illustrates in making money behaviors of the corresponding brain activity;(4) on the go/no go and trust in the questionnaire were related with the degree of brain regions activated in DLPFC also is significantly related to same result(behavior test results score higher on behalf of the trust tendency is to trust others), the higher performance tests score is,the region of the money of DLPFC behavior of brain activation level is higher also.
