Abstract Research in the social sciences has largely relied on Western, Educated, Industrialized, Rich, and Democratic (WEIRD) participants, yet scholars tend to use findings from such WEIRD samples to draw conclusions about human psychology at large. There is, however, one prominent area of psychological science drawing on evolutionary theory that marks a major exception to this trend: research on the nonverbal expression of emotion. We briefly review the major findings from this literature, highlighting the ways in which researchers have effectively used participant samples from “maximally divergent populations” to address questions about universality and, in turn, the evolutionary basis of nonverbal displays.

我们不做怪脸：小规模社会中情绪表达研究的简史

摘要 社会科学研究在很大程度上依赖于西方的、受过教育的、工业化的、富有的和民主的 (WEIRD) 参与者，但学者们倾向于使用来自此类 WEIRD 样本的发现来得出关于人类心理的总体结论。然而，有一个借鉴进化论的心理学突出领域标志着这一趋势的一个主要例外：对情绪的非语言表达的研究。我们简要回顾了该文献的主要发现，重点介绍了研究人员有效使用来自“最大差异群体”的参与者样本的方式，以解决有关普遍性的问题，进而解决非语言展示的进化基础。
