The field of development needs more reliable infant work – improving our measures and methods is at the heart of accurately understanding why children do what they do! However, as scientists, we cannot stop with reliability but must also include measures of validity in our studies. In this commentary, we clarify and expand upon discussions of reliability and measurement error. We also argue for the importance of assessing the validity of our measures and tasks. Indeed, careful considerations of both reliability and validity are necessary for improving infant research.
