Intergroup contact is one of the most promising and effective strategies for reducing prejudice. Importantly, intergroup contact not only improves attitudes towards an encountered outgroup member but also to the outgroup as a whole (i.e., primary transfer effects), to other outgroups (i.e., secondary transfer effects), and even enhances cognitive functioning beyond intergroup relations (i.e., tertiary transfer effect). In this article, we first review the recent developments on primary, secondary, and tertiary contact generalization. We then summarize mechanisms that underlie and condition each of these generalizations. Third, we highlight key critiques against the contact literature identifying avenues for future research on generalization processes. Lastly, we underline the policy value of research on generalization effects.

组间联系影响的概括：新兴研究，政策相关性和未来方向

群体间的联系是减少偏见的最有希望和最有效的策略之一。重要的是，群体间的接触不仅可以​​改善对遇到的外部成员的态度，而且可以改善整体上对外部群体的态度（即一次转移效应），对其他外部群体的态度（即二次转移效应），甚至可以增强除群体间关系之外的认知功能（即，三级转移效果）。在本文中，我们首先回顾一下主要，次要和三级联系泛化的最新发展。然后，我们总结了这些概括的基础和条件。第三，我们重点突出了针对联系文献的关键批评，这些批评为未来的泛化过程研究确定了途径。最后，我们强调了泛化效应研究的政策价值。
