Abstract
Les
capacités linguistiques et cognitives apparaissent avec une énorme
hétérogénéité chez les enfants avec un diagnostic de troubles du spectre
de l'autisme (TSA). Certains
enfants présentent un langage et des capacités
cognitives correspondantes, tandis que d'autres montrent des modèles de développement
plus variables. En
utilisant des échantillons spontanés de langue, nous étudions la
présence et l'étendue de l'altération du langage grammatical dans un
échantillon hétérogène d'enfants avec un diagnostic de TSA.
Les résultats de notre échantillon suggèrent que les enfants avec un diagnostic de TSA peuvent être classés en trois sous-groupes significatifs:
Linguistic and cognitive abilities manifest huge heterogeneity in children with autism spectrum disorder (ASD). Some children present with commensurate language and cognitive abilities, while others show more variable patterns of development. Using spontaneous language samples, we investigate the presence and extent of grammatical language impairment in a heterogeneous sample of children with ASD. Findings from our sample suggest that children with ASD can be categorized into three meaningful subgroups: those with normal language, those with marked difficulty in grammatical production but relatively intact vocabulary, and those with more globally low language abilities. These findings support the use of sensitive assessment measures to evaluate language in autism, as well as the utility of within-disorder comparisons, in order to comprehensively define the various cognitive and linguistic phenotypes in this heterogeneous disorder.

- ceux qui ont une difficulté marquée dans la production grammaticale, mais un vocabulaire relativement intact, et
- ceux ayant des compétences linguistiques plus faibles.
