Commentary on six solutions: Moving forward with measurement in mind.

In their target article, Byers‐Heinlein, Bergman and Savalei describe the neglected challenge of measurement reliability in infancy research. In this commentary, we elaborate on the problem of measurement reliability and demonstrate the problem it poses when using looking time measures to assess individual differences in infancy. We endorse the solutions Byers‐Heinlein et al. propose to increase measurement reliability. In particular, we encourage the field to develop more reliable measures of individual differences infant looking time. [ABSTRACT FROM AUTHOR]
