Relations Between Academic and Behavioral Adaptations: The Antecedent Effects of Executive Function.

Using a large sample (n = 1163) from the National Institute of Child Health and Development Study of Early Child Care and Youth Development, the Random Intercept Cross-Lagged Panel Model was employed to unpack the between-person and within-person aspects in the relations between children's academic performance and externalizing/internalizing behaviors during primary school and examined the predictive role of early executive function. Results showed that the reciprocal relations between state-level fluctuations in children's behavioral problems and academic performance were largely unsupported. Children with more advanced early executive function were found to have better academic performance and fewer behavioral problems throughout primary school, supporting the antecedent role of early executive function. These findings suggest that fostering executive function skills early on could be a key strategy for improving both academic outcomes and behavioral adjustment in children.
