In their methodological article, “Six solutions for more reliable infant research”, Byers-Heinlein, Bergmann and Savalei (2021) present compelling arguments for why developmental researchers should report and consider measures of reliability more frequently in their work. They also provide useful guidance on solutions to this “reliability crisis”. In this commentary, I highlight a further methodological aspect that I think is key to successful and robust infancy research, that of construct validity. I also discuss recent reliability data from my own research on early executive function development, analyses which were directly inspired by the target article.

我们需要谈谈有效性——从早期执行功能研究者的角度评论“更可靠的婴儿研究的六种解决方案”


Byers-Heinlein、Bergmann 和 Savalei（2021）在其方法论文章“更可靠的婴儿研究的六种解决方案”中提出了令人信服的论据，说明为什么发育研究人员应该在工作中更频繁地报告和考虑可靠性衡量标准。它们还为解决这一“可靠性危机”提供了有用的指导。在这篇评论中，我强调了另一个方法论方面，我认为这是成功和稳健的婴儿期研究的关键，即建构有效性。我还讨论了我自己对早期执行功能发展的研究中的最新可靠性数据，这些分析直接受到目标文章的启发。
