Abstract
Dual‐process theories contend that interplay between higher‐order (i.e., regulatory) and lower‐order (i.e., reactive) systems influences the development of attention in early childhood. We therefore investigated interactions between an aspect of children’s top‐down self‐regulation (i.e., effortful control; EC) and positive reactivity (indexed by observed positive affectivity; PA) and negative reactivity (indicated by cortisol stress reactivity and observed fear) in predicting children’s early attention problems. We found that observed EC at age 3 predictedlower attention problems two years later, controlling for attention problems at baseline. Importantly, thepredictive effect of ECwas more pronounced for children higher in cortisol stress reactivity at age 3; this pattern was not found for observed PA or fear. Findings align with dual‐process developmental theories that emphasize the dynamics between regulatory and reactive processes in shaping child development. Our study providesthe first evidence supporting dual‐process interactions in the domain of attention problems and has implications for identifying early risk markers and informing early prevention programs for children at greater risk for attention problems.
