Distinguishing Direct and Indirect Effects of Executive Functions on Reading Comprehension in Adolescents

Abstract

This study investigated direct and indirect effects of executive functions on reading comprehension in adolescents (N = 87, M = 14.0 years, SD = 1.5) by testing for parallel mediation of effects of working memory, task-switching, and inhibitory control via decoding and text recall/inference. Working memory showed direct and indirect effects on passage comprehension, the latter mediated by text recall/inference. Task-switching was associated with decoding but its relation to passage comprehension was not significant. Inhibitory control showed indirect effects on passage comprehension via decoding and text recall/inference. Results indicate overlapping but distinct contributions of executive functions to reading skills.
