Atypies de la fluence chez les enfants et adolescents avec TSA de haut niveau de fonctionnement : étude de l’occurrence de l’échodysphémie et des broken-words

Abstract : Echodysphemia is a fluency disorder characterized by a repetition of the end of words or a vocal interruption in the syllable nucleus. It seems to mainly concern children with a neurodevelopmental disorder (DND). Several cases in literature were diagnosed or suggested an autism spectrum disorder (ASD), with impaired communication and relationship contact. Precisely, children with ASD often exhibit altered prosody, including monotonous or stereotypical intonation, wrongly placed breaks and atypical disfluences. We aimed to study the occurrence of these atypical disfluences in children and adolescents with high functioning ASD. Our hypothesis was that these disfluences are not an epiphenomenon in this population. We have built a linguistic corpus from video recordings of ADOS passages, to identify disfluences in narrative and discursive tasks. We included among these disfluences echodysphemia and broken-words as well, which seemed to be a neighboring phenomenon. Our results suggest that a large proportion of children with ASD produce these disfluences, although in varying amounts and randomly. Thus, the identification of these atypical disfluences could be part of diagnostic interest if they were found to be pathognomonic of ASD or DND.
