本研究模拟公共物品两难困境范式,以初中生为被试,通过两个实验分别考察道德惩罚和关系惩罚对不同性别和社会价值取向个体合作行为的影响。结果发现：（1）两种惩罚条件下初中生的合作水平均显著高于无惩罚条件,但当惩罚撤除后只有关系惩罚条件下的效应还存在;（2）初中女生在两种惩罚条件下的合作水平均显著高于无惩罚条件,而男生只在关系惩罚条件下出现该情况;（3）亲社会取向与亲自我取向初中生在两种惩罚阶段均表现出更高的合作水平,但在惩罚撤除后,只有亲社会取向者保持了高合作水平。这些结果表明,关系惩罚的作用较为持久,且对男生的影响更为突出,不过两种惩罚在亲社会取向者身上均显现出延后效应。

英文摘要：

Several factors can account for the cooperative behaviors in social dilemmas, which include individual differences, reward and punishment system, task design and so on. People have a strong aversion to being the ＂sucker＂ in social dilemma situations so that those who prefer cooperation may be willing to punish free-riding. Researches demonstrated that although punishment could promote people＇s cooperative behaviors temperately, their cooperation levels would drop down to the baseline when the punishment was removed. In previous studies, material punishment was adopted most frequently, however, social punishment has not been sufficiently investigated. Furthermore, there is no unanimous conclusion towards the issue whether the cooperation of the juveniles has any gender differences. So this study mainly examined the effects of moral punishment and interpersonal punishment on the junior middle school student＇s cooperative behaviors. Last but not least, social value orientation is a relatively stable individual state and is defined as a tendency of allocation proportion between individual and others. Therefore, we further explored the relationship between social value orientation and student＇s cooperative behaviors under different types of punishment. Accordingly, the present study consisted of 2 experiments. The first experiment was organized into a 3 × 2 factorial design. The first factor was the type of punishment, consisting of 3 levels： moral punishment, interpersonal punishment and no punishment. The second factor was the phase of punishment, consisting of 2 levels： punishment in the first phase and no punishment in the second one. Specifically, participants were randomly assigned to the three types of punishment. For punishment groups, participants were given the two phases of punishment. The second experiment was organized into a 3 × 2× 2 factorial design. The first two factors were the same as experiment 1. The third factor was the type of social value orientation, encompassing 2 levels：
