Children’s ability to control their own thoughts and actions, or ‘executive function’ (EF), has been a topic of intense interest in the field of developmental science for the past two decades. While enormous progress has been made in understanding the social correlates and consequences of individual differences in executive function in the preschool years, relatively few studies have sought to examine normative individual differences in executive function in the first two years of life. In this seminar, Dr Devine will present data from a new longitudinal study of children and parents to elucidate the early predictors and social correlates of executive function in the first two years of life.
