Executive function (EF) skills are a set of attention-regulation skills involved in intentional, goal-directed behavior that include (but are not limited to) the cool EF skills of working memory, cognitive flexibility, and inhibitory control, and also the hot EF skill of intentional reevaluation. These skills are inevitably expressed in goal- and…

Few studies have examined the influence of environmental factors on children's executive functioning (EF) performance. The present study examined the effects of a punitive vs. non-punitive school environment on West African children's EF skills. Tasks included a "cool" (relatively non-affective) and "hot" (relatively…

The aim of this report was to investigate the prospective links between infant sleep regulation and subsequent executive functioning (EF). The authors assessed sleep regulation through a parent sleep diary when children were 12 and 18 months old (N = 60). Child EF was assessed at 18 and 26 months of age. Higher proportions of total sleep occurring…

The chapters in this issue revisit the social origins of the development of executive function (EF) through both empirical examination of the contexts in which EF development occurs (in vivo), as well as its social antecedents and consequences. Importantly, they also point to new directions in studying the social foundations of neurodevelopment,…

In keeping with proposals emphasizing the role of early experience in infant brain development, this study investigated the prospective links between quality of parent-infant interactions and subsequent child executive functioning (EF), including working memory, impulse control, and set shifting. Maternal sensitivity, mind-mindedness and autonomy…

Given that gestures may provide access to transitions in cognitive development, preschoolers' performance on standard tasks was compared with their performance on a new gesture false belief task. Experiment 1 confirmed that children (N45, M age54 months) responded consistently on two gesture tasks and that there is dramatic improvement on both the…

Three studies examined whether preschoolers' difficulties with deception and false belief arise from lack of inhibitory control rather than conceptual deficit. Found that 3-year olds deceived frequently under conditions requiring relatively low inhibitory control, but not high inhibitory control. Findings were not due to social intimidation, and…

Advanced inhibitory control skills have been found in bilingual speakers as compared to monolingual controls ( Bialystok, 1999 ). We examined whether this effect is generalized to an unstudied language group (Spanish-English bilingual) and multiple measures of executive function by administering a battery of tasks to 50 kindergarten children drawn…

Examined relation between early fantasy/pretense and knowledge about mental life in 3- and 4-year olds. Found that performance on theory of mind tasks was significantly intercorrelated when effects of verbal intelligence and age were statistically controlled. Individual differences in fantasy/pretense were related to theory of mind performance in…
