Étude des spécificités du développement langagier expressif des enfants avec TSA au moyen du DLPF-A

Abstract : The expressive language development of children with Autism Spectrum Disorders (ASDs) has lexical, syntactic and pragmatic specificities. This study compares the productions reported using the DLPF-A (Développement du Langage de Production en Français – version de synthèse Adaptée) parental survey, which simultaneously evaluates these three dimensions. The language productions of children with ASD, whose verbal development age was between 21 and 37 months, were compared to those of children with ordinary development (OD). The lexical explosion observed in the language of OD children around 30 months of age was less pronounced in the language of children with ASDs, particularly for grammatical words and predicates. Their lexicon contains more names. In syntax, from the lexical explosion, children with ASD use comparatively fewer verbal inflections and complex sentences. As they grow older, the gap widens between their pragmatic skills, especially in language use and message organization. Some of the interdependencies observed between the three language domains in OD children are not observed in the language of children with ASDs. Complex sentence development does not improve with increasing lexical stock. Similarly, language use is not correlated with the child's grammatical progress. This study confirms the relevance of an adapted parental report for the early language assessment of children with ASDs, in accordance with the recommendations of the HAS (2018). It also opens up specific avenues for the speech and language remediation of expressive language in children with ASDs.
