Early Development of Executive Attention

Conejero A and Rueda MR

Executive attention (EA) encompasses a variety of attention mechanisms implicated in the control of thoughts and behavior. The emergence of EA skills depends on the maturation of frontal brain structures. Evidence in the past years has shown that frontal brain structures related to EA are already functional in the first months of life and first signs of EA can be observed by the second half of the first year of life. Given the importance of EA to a wide range of developmental outcomes (e.g. academic and professional outcomes, socialization, psychological wellbeing, etc.), understanding early stages of development is of great interest for the promotion of EA and the prevention of EA-related deficits over the course of development. Despite its relevance, relatively little is known about the development of EA before the preschool years. This paper aims at providing a selective review of the existing literature about the early development of EA. We present the principal measures of EA for infants and toddlers available to date. We also review main findings on behavioral as well as brain mechanisms of EA in infancy and toddlerhood. Finally, we summarize research on early indicators of EA and its implication for the early detection of some developmental disorders.
