This article presents two studies investigating the role of executive functioning in written text comprehension in children and adolescents. In a first study, the involvement of executive functions in reading comprehension performance was examined in normally developing children in fifth grade. Two aspects of text comprehension were differentiated: literal and inferential processes. The results demonstrated that while three aspects of executive functioning (working memory, planning, and inhibition processes) were significantly predictive of the performance on the inferential questions of the comprehension test, these factors did not predict the scores on the literal tasks of the test. In a second experiment, the linguistic and cognitive profiles of children in third/fifth and seventh/ninth grades with a specific reading comprehension deficit were examined. This analysis revealed that the deficits experienced by the less skilled comprehenders in both the linguistic and the executive domains could evolve over time. As a result, linguistic factors do not make it possible to distinguish between good and poor comprehenders among the group of older children, whereas the difficulties relating to executive processing remain stable over development. These findings are discussed in the context of the need to take account of the executive difficulties that characterize less skilled comprehenders of any age, especially for remediation purposes.
