This article reviews research on the construct of emotion regulation in you
ng children. The lack of consensus with regard to a definition of emotion r
egulation notwithstanding, it appears that biological and behavioral proces
ses involved in emotion regulation can be reliably measured early in life.
Such indices of reactivity may be useful in identifying children at risk fo
r developmental psychopathology, but the predictive utility of these indice
s has yet to be established. Measurement issues and factors hypothesized to
affect an infant's risk for dysregulation, such as cam-giving factors, are
presented. The implications of continued programmatic research on emotion
dysregulation early in life are discussed.
