Fonctions exécutives et orthographe : développement et lien chez les enfants libanais bilingues francophones (DT et TSLE) du CE1 au CM1

Abstract : Our research work focuses on the development of executive functions which involve cognitive processes such as : inhibition, working memory, flexibility and planning as well as on their implication in the written language of bilingual children, field that is not well explored in the literature. Considering the school learning particularities in Lebanon and the spelling complexities of each of the two languages studied : French and Arabic, the bilingual child is faced with demands that require additional cognitive effort. Three experimental studies have been carried out in this thesis to study the development then the link between executive functions (inhibition, working memory, flexibility and planning) and spelling in French and Arabic languages. Ninety children with typical development (DT) and ninety children with a specific written language disorder (TSLE), schooled in Grade 2, 3 and 4, were recruited from Lebanese public and private primary schools. The results of the executive functions and spelling tests show mainly that performances at all executive functions are more efficient in DT children than in TSLE children. We were also able to confirm that the spelling performances of DT children is greater than that of TSLE children in accuracy and speed of treatment. However, these results are nuanced as to the percentages of errors in one language compared to the other and depending on each class level. Finally, our results showed that all executive functions are more involved in the Arabic language than in the French language, and correlated with the accuracy and speed of spelling, by taking into consideration the entire population. These results were discussed in relation to Lebanese school curricula. In the end, this study can explain the cognitive components (inhibition, working memory, flexibility and planning) underlying the French and Arabic spelling, languages that have many writing peculiarities, for a better rehabilitation and management of disorders in speech therapy and in pedagogy.
