In a wide ranging article in this journal, Byers-Heinlein et al. (2022) make a persuasive case for paying close attention to reliability in developmental research. They focus on measurement reliability, which indexes how well individuals can be ranked across repeated measurements. We highlight the importance of measurement precision as a complement to understanding measurement reliability. We describe how this more absolute type of reliability can be quantified by the within-participant standard deviation across trials, also known as the standard error of measurement (SEM). We outline how reporting and understanding measurement precision can play a key role in achieving the ‘six solutions’ for improving reliability in developmental research offered by Byers-Heinlein et al.

发展心理学家应该关心测量精度

Byers-Heinlein 等人在本期刊的一篇范围广泛的文章中。（2022）提出了一个有说服力的案例，以密切关注发展研究的可靠性。他们专注于测量可靠性，它表明个人在重复测量中的排名。我们强调测量精度作为理解测量可靠性的补充的重要性。我们描述了如何通过试验中的参与者内部标准偏差（也称为测量标准误差 (SEM)）来量化这种更绝对的可靠性类型。我们概述了报告和理解测量精度如何在实现“六种解决方案”以提高 Byers-Heinlein 等人提供的发展研究可靠性方面发挥关键作用。
