Abstract: In real life, people always interact with persons of different characteristics. The result of social interaction not only depends on the characteristics of the individual itself, but also is affected by another participant. People can form a social perception of another person according to his/her moral choice or judgment, they also will actively perceive the behavior tendency of strange opponent in the previous interaction, and then use the information of peers to predict the future behavior of their peers.This study will investigate cooperative behavior of individuals which interact with opponents of different characteristics. People may change their own interactive strategy according to the moral tendency(deontology or consequentialism) and behavior pattern of others. This study will show the opponents' moral orientation (deontology and consequentialism) before the game, or by setting up the cooperative type (cooperative or competitive) of the opponents in the interaction. This study assumes that when individuals perceived that opponents are more competitive than themselves, people Will rationally choose cooperation to avoid more losses, and in the face of relatively cooperative opponents, will choose more aggression to make their own greater benefits. Individuals will not only form a certain social perception of their peers according to the game situation in all previous rounds, and use this information to determine the choice of the current round, but may also determine the choice of their current round according to the results of the recent, that is, the last round.The influence about outcome of previous round to current round will be concerned. In this study, two between-participants Chicken Game were designed to investigate this issue. In this study, participants will play the games with different "opponents" and maximize their own gains. In Experiment 1, the participants first perceived the opponent as deontology or consequentialism through the opponent's answer about the moral dilemma, and then carried out Chicken Game, the opponent’s decisions were randomly predetermined by a series of equally-probable cooperation and aggression decisions. In Experiment 2, the participants perceived the characteristics of the opponents as cooperative(randomly predetermined by a series of 80%-probable cooperation) or competitive (randomly predetermined by a series of 20%-probable cooperation) in the first half of the experiment through 50 rounds of interaction with the opponent, while the cooperation rate of the opponent returned to 50% in the latter part of the Experiment 2. The results indicated that: (1) There is no significant difference in the cooperation rate between the deontology group and consequentialism group, and there is no significant difference in the cooperation rate between the competitive group and the cooperative group. (2) When interacting with the deontology and the cooperative opponent, the behavior of the participants is not significantly affected by the result of the previous trial. (3) When the opponent is consequentialism, compared with individual chooses to cooperate and the opponent chooses to aggressive in the previous trial, when both players chose to cooperate, the participants were more tended to cooperate in the current trial. (4) In the competitive group, when both player choose to cooperate, the participants were more inclined to cooperate compared to the previous individual choice of aggression and the opponent chooses to cooperate.

摘要： 人类的生存繁衍依赖于人们之间的相互合作，合作与冲突行为的研究近年来成为心理学的研究热点。本研究通过实验程序操纵Chicken Game中博弈同伴的特点，考察个体在社会困境中面对不同特点同伴时的合作行为。结果发现：(1)同伴道义论组和功利论组总和解率没有显著差异，同伴竞争组和合作组的总和解率也没有显著差异。(2)在与道义论以及合作型的同伴互动时，个体的行为没有明显受到上次博弈反馈的影响。(3)当同伴为功利论时，相比于上次博弈个体选择和解而同伴选择进攻，双方都选择和解时个体在当前博弈中更倾向于和解；(4)在同伴竞争组中，相比于上次博弈个体选择进攻而同伴选择和解，双方都选择和解时被试在当前博弈中会更倾向于和解。实验结果表明个体在博弈任务中会受到同伴特点的影响，并且同伴在博弈中的行为特点的影响更为显著。本研究从同伴特点来考察个体的合作行为，揭示了影响个体博弈行为的一种因素。
