Abstract:
In this study, we explored whether measures of emotion regulation, physiological regulation, and inhibitory control form a global indicator of individual regulation. This was tested using data from 80 toddlers during a laboratory visit at age 24 months. Principal components analyses were used to examine convergence of different facets of regulation. Emotion regulation was captured dynamically using linear and quadratic trends in distress and compared to traditional composite measures. Evidence for an individual capacity for regulation was not found using either measure. Theoretical and methodological implications for future examinations of regulation are discussed.
