三个实验考察了群体内社会影响在群体间竞争中的作用。在共同命运控制情境下，实验1的参与者在有共同利益的社会支持时比在没有共同利益的社会支持时表现出更多的群体间竞争。实验2显示，在囚徒困境博弈情境下，社会支持效应在结果不一致程度较低时强于结果不一致程度较高时。实验3的结果与社会支持效应在结果高度不一致时减弱的可能性一致，因为在这些情况下，群体间竞争是由群体利益规范规定的。讨论了这些发现对理解个体-群体间不连续性的前因的意义。
Three experiments examined the role of intragroup social influence in intergroup competition. In the context of a mutual fate control situation, participants in Experiment 1 demonstrated more intergroup competition in the presence than in the absence of social support for shared self-interest. Experiment 2 revealed that, in the context of a Prisoner's Dilemma Game, this social support effect was stronger when noncorrespondence of outcomes between the interacting groups was low than when it was high. Results from Experiment 3 were consistent with the possibility that the effect of social support is attenuated when noncorrespondence of outcomes is high because under these circumstances intergroup competition is prescribed by a norm of group interest. The implications of these findings for understanding the antecedents of interindividual-intergroup discontinuity are discussed.
