This research investigated whether ingroup norm moderates the effect of positive or prosocial interactions on the understanding of intergroup prosocial behaviors. Among four experiments in three different cultural samples (U.S. Americans, Kosovan Serbs, and Kosovan Albanians; N = 808), results showed that participants attributed fewer prosocial motives and reported less willingness to accept help when the helper was an outgroup than an ingroup member. However, these effects were weaker or nonsignificant in the tolerant norm condition, as compared to the intolerant norm or control conditions. In addition, participants were more willing to interact with the outgroup (vs. ingroup) helper in the tolerant norm condition, as compared to the intolerant norm or control conditions. Finally, normative expectations, the attribution of prosocial motives to the helper, and the anticipated quality of the interaction with the helper sequentially explained the observed effects. The theoretical and practical implications of these results for intergroup help and intergroup contact literature are discussed.

这项研究调查了群体内规范是否缓和了积极或亲社会互动对群体间亲社会行为的理解的影响。在三个不同文化样本（美国美国人，科索沃塞族人和科索沃阿尔巴尼亚人；N= 808），结果表明，参与者所提供的亲社会动机更少，并且报告说当帮助者为外出群体时，接受接受帮助的意愿要少于内在成员。但是，与不宽容的规范或控制条件相比，这些影响在宽容的规范条件下较弱或不显着。此外，与不宽容的规范或控制条件相比，参与者更愿意在宽容的规范条件下与小组外（与组内）帮助者互动。最后，规范性期望，亲社会动机对帮助者的归属以及与帮助者互动的预期质量依次解释了观察到的效果。讨论了这些结果对小组间帮助和小组间联系文献的理论和实践意义。
