L ’objectif de ce travail est d’évaluer le dédeveloppement lexical, précoce chez les enfants bilingues et d’explorer le lien possible entre la, taille du vocabulaire et les fonctions exécutives. Nous avons testé 15,bilingues français-portugais (7 de 16 mois et 8 de 24 mois). Leur, développement langagier a été évalué avec l'Inventaire du développement, communicatif français et portugais (adaptations du CDI MacArthur-Bates, Fenson et al., 2007). Des questionnaires parentaux ont été utilisés pour,évaluer la dominance linguistique (PaBiQ, Tuller, 2015), les stades de, développement (ASQ-3™, Squires et al., 2009) et les fonctions exécutives,(BRIEF-P, Gioia, Aspy, … Isquith, 2003). Nous avons calculé la taille du, vocabulaire dans chacune des langues, le vocabulaire total et le vocabulaire, conceptuel total et comparé avec les normes des monolingues. Presque, tous les participants ont un vocabulaire total dans chacune des langues,(français ou portugais) et un vocabulaire conceptuel total similaire à celui, des monolingues portugais et français. Leur vocabulaire total,(français+portugais) est par contre supérieur à celui des monolingues. Il, existe une corrélation entre la taille du vocabulaire et la mémoire de travail,(Stokes & Klee, 2009), mais aucune avec l'inhibition. Ces résultats donnent, un meilleur aperçu du processus de développement du langage bilingue.
Abstract
Does first word development in bilingual French-,Portuguese toddlers mirror monolingual one? A study exploring, executive function abilities. We aimed at observing early lexical, development in French-Portuguese bilingual children and explore the link, between vocabulary size and executive functions. We tested 15 bilingual, French-Portuguese children, 7 were 16-month-old and 8 were 24-monthold.,Their language development was assessed with the French and, Portuguese Communicative Development Inventory (adaptations of, MacArthur-Bates CDI [Fenson et al., 2007]). Parental questionnaires were, also used to assess language dominance (PaBiQ [Tuller, 2015]), developmental stages (ASQ-3™; Squires et al., 2009) and executive, functions (BRIEF-P; Gioia, Aspy, & Isquith, 2003). We also calculated the, total words in each language, the total vocabulary (TV) in each language, and the total conceptual vocabulary (TCV) and compared them with the, respective norms for monolinguals. The results showed that almost all, participants had the same performance in vocabulary acquisition as their, monolingual pairs of Portuguese and French, both for total words in each, language and TCV. Moreover, their TV (Portuguese+French) exceeded the, vocabulary of monolinguals. For executive functions, a significant, correlation between vocabulary size and working memory appeared,(Stokes & Klee, 2009), but not with inhibition. Our results shed light on, the process of bilingual language development, and help to change beliefs, about negative effects of bilingualism on children language development.
