Preschool Sleep Problems and Differential Associations With Specific Aspects of Executive Control in Early Elementary School

Abstract

This study examined the differential associations between parent-reported child sleep problems in preschool and specific aspects of executive control in early elementary school in a large sample of typically developing children (N = 215). Consistent with expectations, sleep problems were negatively associated with performance on tasks assessing working memory and interference suppression inhibition, even after controlling for general cognitive abilities, but not with flexible shifting or response inhibition. The findings add to the literature on cognitive impairments associated with pediatric sleep loss and highlight the need for early intervention for children with sleep problems to promote healthy cognitive development.
