Etude développementale lexicale et morphosyntaxique d’enfants avec TSA au moyen du questionnaire parental DLPF

Abstract : Psycholinguistic work on the development of expressive language in young French-speaking children with autism is still too limited. However, lexical, morphosyntactic and pragmatic language features have been highlighted in their productions (Foudon, 2008; Lavielle-Guida, 2007, 2016; Lavielle, Bassano, Adrien and Barthelemy, 2003). The present transversal and descriptive study seeks to characterize finely the lexical and morphosyntactic characteristics by means of the parental questionnaire DLPF, Development of the French Production Language, in its new version called « DLPF Synthesis Version, 18 to 42 months ». This study analyses the productions of eight autistic children aged 21 to 37 months of verbal development compared to those of normotypic children of the same age. The result is an over-representation of paralexical items, an equivalent proportion of content words and an under-representation of grammatical words in lexicon ; as well as an under-representation of regular verbal forms, complex structures and sentences in morphosyntax. These results, beyond the research, open up remedial perspectives allowing speech therapists to concretely target the lexical and morphosyntactic domains to work on.
