The papers in this special issue highlight the diversity of methods us
ed to study the development of emotion regulation, and the substantial
progress that has been made in understanding how children learn to ma
nage strong emotions. This commentary poses 10 questions that focus on
how developmental psychologists conceptualize emotions and regulation
, measure emotions in research, and understand the interplay of indivi
dual and contextual variables. The discussion here outlines issues to
guide future work; answers to these substantial questions will require
much additional research.
