Typically developing children (N = 80) completed tasks assessing their cool (inhibition, working memory, planning) and hot EF (affective decision making, delay of gratification) skills at 5 years old. Longitudinal data were collected from teachers that rated childrenĄ¯s aggression when they were 5, 5.5, and 6 years old. Inhibition at 5 years old predicted changes in physical and relational aggression between 5 and 6 years old. Early cool EF, but not hot EF, may therefore be associated with aggression and inhibitory control specifically with changes in aggression during early childhood %K Aggression %K executive function %K early childhood %U https://journals.sagepub.com/doi/full/10.1177/0165025418798498
