中文摘要：

通过两项研究考查大学生在社会困境中的行为决策及公平感体验，检验社会价值取向的影响作用，有效被试分别为85名和84名。结果表明：（1）亲社会者比亲自我者更倾向做公平决策；信息对称比不对称条件更促进被试做公平决策；女生比男生更倾向做公平决策。（2）性别在社会价值取向与信息对称性对公平决策的影响中起调节作用，社会价值取向显著影响男生的公平决策，信息对称性显著影响女生的公平决策。（3）社会价值取向显著影响个体对不公平的容忍度，亲社会者更不容忍不公平行为。（4）对于利己的不公平行为，被试都倾向接受，亲社会者并不比亲自我者体验到更强的内疚情绪；对于不利己的不公平行为，被试都倾向拒绝，且产生较强的不公平感及气愤情绪。

英文摘要：

Through two studies, the present research investigated behavioral decision-making and sense of fairness of college students in social dilemmas and the effect of social value orientation was tested, with 85 participants in study 1 and 84 participants in study 2. Results indicated that： （1） Prosocials were more inclined to make fair decisions than proselfs. Compared with asymmetric information condition, symmetric information could promote participants＇ fair decisions. Moreover, females were more likely to make fair decisions than males. （2） Social value orientation and information symmetry influenced fairness decision-making through the moderating effect of gender. While males＇ fairness decision-making was only significantly influenced by social value orientation, females＇ fairness decision-making was only significantly influenced by information symmetry. （3） Social value orientation significantly influenced individuals＇ tolerance of unfairness. Specifically, prosocials were less tolerated with unfairness than proselfs. （4） Participants were inclined to accept unfair behavior favorable for them but reject unfair behavior unfavorable for them. When faced with unfair behavior favorable for them, prosocials didn＇t experience stronger emotion of guilty. However, for participants with prosocial and proself orientations, unfair behavior unfavorable for them triggered stronger sense of unfairness, accompanied by anger.
