This article reviews over sixty years of research on psychological barriers to intergroup conflict resolution and finds that scholars have identified eighty nominally different barriers that create or exacerbate intergroup conflict. In order to create a tractable list that would be more helpful to future scholars and practitioners, we consolidate this vast literature (e.g., by eliminating substantive and conceptual redundancies) to produce a list of twenty‐six “unique” psychological barriers. We further organize this inventory of barriers with a framework that distinguishes between “cognitive,” “affective,” and “motivated” psychological barriers. To better understand the literature ecosystem of research on psychological barriers, we employ a data visualization tool to illustrate the extent to which each of the twenty‐six unique barriers has been studied conjointly with every other barrier in the articles we reviewed. We then shift our attention to the work of scholars who have attempted, experimentally, to attenuate psychological barriers in negotiation and conflict settings, and identify five primary methods for doing so. Finally, we discuss the implications of our review for future work in this field.

解决群体间冲突的心理障碍：对文学的广泛回顾和巩固

本文回顾了六十多年来对解决群体间冲突的心理障碍的研究，发现学者们已经确定了八十种名义上不同的障碍，这些障碍会造成或加剧群体间的冲突。为了创建一个对将来的学者和从业者更有用的易于处理的清单，我们将大量文献（例如，通过消除实质性和概念性的冗余）加以合并以产生二十六个“独特”的心理障碍清单。我们进一步用一个区分“认知”，“情感”和“动机”心理障碍的框架来组织这些障碍清单。为了更好地了解心理障碍研究的文学生态系统，我们使用一种数据可视化工具来说明我们所审查的文章中对二十六个独特障碍中的每一个与其他障碍进行了联合研究的程度。然后，我们将注意力转移到尝试通过实验来减轻谈判和冲突环境中的心理障碍并确定五种主要方法的学者的工作上。最后，我们讨论了我们的审查对于该领域未来工作的意义。
