Abstract Like psychology more broadly, developmental psychology has long suffered from a narrow focus on children from WEIRD societies—or those that are Western, Educated, Industrialized, Rich, and Democratic. In this review, we discuss how developmental scientists have sought to correct this bias through two complementary approaches: one centered on detailed, ethnographic investigations of child development within populations (increasing the depth of our understanding) and one focused on larger, multi-site studies that test children on standardized tasks across populations (increasing breadth). We review key papers from each of these approaches, describe how they are currently practiced, and discuss their strengths and weaknesses. Next, we highlight exemplary papers from the adult literature that offer useful insights, namely the importance of formal modeling and a greater focus on studying variation at multiple levels of analysis. We end by outlining best practices for future waves of cross-cultural, developmental science. Overall, we argue that a more integrated perspective, combining the strengths of the breadth & depth approaches, can help better elucidate the developmental origins of human behavioral diversity.

跨文化发展心理学：整合方法和关键见解

摘要 与更广泛的心理学一样，发展心理学长期以来一直受到对来自奇怪社会或西方、受过教育、工业化、富裕和民主社会的儿童的狭隘关注。在这篇综述中，我们讨论了发育科学家如何通过两种互补的方法来纠正这种偏见：一种侧重于对人群中儿童发展的详细的人种学调查（增加我们的理解深度），另一种侧重于更大的多地点研究测试儿童跨人群的标准化任务（增加广度）。我们回顾了每种方法的关键论文，描述了它们目前的实践方式，并讨论了它们的优点和缺点。接下来，我们重点介绍成人文献中提供有用见解的示范论文，即正式建模的重要性以及更加关注在多个分析级别上研究变化的重要性。我们最后概述了未来跨文化发展科学浪潮的最佳实践。总的来说，我们认为，结合广度和深度方法的优势的更综合的观点可以帮助更好地阐明人类行为多样性的发展起源。
