In this comment, I first highlight the contributions of Robinson-Cimpian, Lubienski, Ganley, and Copur-Gencturk (2014) in particular and a more interdisciplinary approach in general for the subdiscipline of developmental psychology. Second, I identify some historic methodological foci of psychology and encourage Robinson-Cimpian et al. to consider these possibilities. Finally, I end with my perception that the emerging subdiscipline of developmental methodology can provide a common context for interdisciplinary dialogue in developmental science.
