Socio-emotional school behavior and learning are both fundamental aspects of children's development influenced by cognitive control processes named Executive Functions (EF). Yet, research on school-age children has often focused on the relationship between EF and learning skills overlooking that of EF and school behavior, which has usually been examined among preschoolers. The current study investigated the contribution of EF in both school behavior and learning in school-age children. One hundred forty-six III--V graders were assessed using text comprehension and EF tasks and evaluated by teachers-rated inventories on behavioral difficulties and EF within the school context. The results suggested a different involvement of direct and indirect EF measures in the two domains considered: controlling for socioeconomic level and age, an EF direct measure, predicted reading comprehension whereas teacher-reported EF related to both behavior and text comprehension. The results contribute to defining the role of cognitive control processes on school behavior and learning in school-age children.
