Abstract：
This research investigated how an instance of intergroup helping affects intergroup attitudes and cooperative behavior. Past research demonstrates that helping behavior elicits prosociality, both reciprocally and toward uninvolved third parties. However, much of this research has either ignored group membership altogether or has assumed a shared group identity between benefactor and beneficiary. Where intergroup helping has been directly evaluated, more negative intergroup attitudes are often observed. The current study examined the effects of an instance of intergroup helping, introduced during a card game, on the beneficiary\'s attitudes of closeness and cooperative trading behavior as well as those of ingroup and outgroup witnesses to the helping act. Results from this well-powered study (N = 1,249) indicate that although intergroup helping is less likely to impact feelings of closeness, intergroup cooperative trading increases for both the beneficiary and the intergroup observers. These findings add to the understanding of how helping impacts intergroup relations.
摘要：
这项研究调查了群体间帮助的实例如何影响群体间的态度和合作行为。过去的研究表明，帮助行为会引发亲社会，既对等又对不涉及的第三方。然而,这项研究中的大部分要么完全忽略了组成员资格，要么假定了恩人和受益人之间共享的群体身份。在直接评估了群体间帮助的地方，经常观察到更多消极的群体间态度。当前的研究检查了群体间帮助的实例的影响，在纸牌游戏中介绍，关于受益人对亲密关系和合作交易行为的态度以及团体内和团体外证人对帮助行为的态度。这项有力的研究（N=1,249）的结果表明，尽管小组间的帮助不太可能影响亲密感，团体间合作交易对受益人和团体间观察员都增加了。这些发现增加了对帮助如何影响群体间关系的理解。
