In psychology, authors have shined a light on a lack of ethnic/racial and cultural diversity in sampling and scholarship. These issues pertain also to the study of aging and lifespan development. This article presents examples of how diverse sampling, across ethnic/racial groups and cultures, enriches theories of aging and adult development. There remain, however, numerous theoretical insights that are yet to be uncovered by future research that seeks to further diversify this sub-discipline. Good practices and avenues to diversification are considered, including targeted sampling of minority groups in the community, online sampling with use of data screening tools, lifespan-orientated surveys initiated in non-Western countries, and a redress of the balance in the perceived value of research from different regions of the world.

衰老和寿命发展研究的多样性

在心理学领域，作者们揭示了抽样和学术研究中缺乏民族/种族和文化多样性的问题。这些问题也涉及衰老和寿命发展的研究。本文提供了一些例子，说明跨民族/种族群体和文化的多样化抽样如何丰富老龄化和成人发展理论。然而，仍有许多理论见解尚未被未来的研究发现，这些研究旨在进一步使这一子学科多样化。考虑了良好的做法和多样化途径，包括对社区中的少数群体进行有针对性的抽样、使用数据筛选工具进行在线抽样、在非西方国家发起的以寿命为导向的调查，以及纠正人们感知价值的平衡。来自世界不同地区的研究。
