Development of inhibition and working memory in school-age Moroccan children

Abstract

ABSTRACT Studies regarding executive functions (EFs) in children rarely focus on populations of North Africa countries. In this context, this research aimed to adapt EFs tests to the Moroccan context and provide preliminary normative data on the development of inhibitory control and working memory (WM). In addition, the executive performance of school-age Moroccan children was examined, as well as the effects of gender, parents’ education level and multilingualism. The sample included 115 children at age 7 to 12 from Fes city. Results showed that the translation and adaptation steps were sufficient for the cross-cultural adaptation of the tasks. In addition, an overall effect of age on inhibition and WM performances was found, whereas gender and parents’ education level showed non-significant effects. Multilingualism effects had a partial positive influence on EFs, with improved scores on a few executive tasks for multilingual children compared to their bilingual peers. Overall, results suggest that EFs in school-age Moroccan children operate on relatively homogeneous development trajectories, marked by improvements that differ according to tasks. As neuropsychological tools and normative data are still lacking in Morocco, this study helps better understand EFs development of children in this country.
