Byers-Heinlein，Bergmann和Savalei(2021)在他们的方法论文章《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点，解释了为什么发展研究人员应该在他们的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，那就是结构效度。我还讨论了我自己对早期执行功能发展的研究的最新可靠性数据，这些分析直接受到目标文章的启发。考虑测量的可靠性和影响大小对于稳健的婴儿研究和优化婴儿任务以测量群体水平的影响或个体差异是重要的。构建效度--确保我们衡量的是我们认为正在衡量的东西--也很重要。群体水平上的强大效应可能并不总是限制可靠性--它取决于婴儿之间的真实变异量。
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. Considering measurement reliability and effect sizes is important for robust infant research and for optimising infant tasks to measure group‐level effects or individual differences. Construct validity – making sure that we measure what we think we are measuring – is also important. A robust effect at the group‐level may not always restrict reliability – it depends on the amount of true variation between infants.
