Indices de la non-compréhension des échecs de communication dans le syndrome du X fragile, le syndrome de Down et le trouble du spectre de l'autisme

Aperçu : La capacité à indiquer un échec dans la compéhension d'un message est une compétence pragmatique (sociale) de langage critique pour gérer les ruptures de communication et soutenir les échanges de communication réussis. A la fin de la lecture de cet article, les lecteurs auront appris (1) les profils socio-communicatifs des jeunes avec SXF, SD et TSA, (2) l'importance de signaler la non-compréhension en réponse à un message confus, et (3) la ou les similitudes et les différences de signalisation de non-compréhension chez les jeunes avec SXF (avec et sans TSA), de SD, de TSA idiopathique et de TD.

Abstract

The ability to indicate a failure to understand a message is a critical pragmatic (social) language skill for managing communication breakdowns and supporting successful communicative exchanges. The current study examined the ability to signal noncomprehension across different types of confusing message conditions in children and adolescents with fragile X syndrome (FXS), Down syndrome (DS), autism spectrum disorder (ASD), and typical development (TD). Controlling for nonverbal mental age and receptive vocabulary skills, youth with comorbid FXS and ASD and those with DS were less likely than TD controls to signal noncomprehension of confusing messages. Youth with FXS without ASD and those with idiopathic ASD did not differ from controls. No sex differences were detected in any group. Findings contribute to current knowledge of pragmatic profiles in different forms of genetically-based neurodevelopmental disorders associated with intellectual disability, and the role of sex in the expression of such profiles.

LEARNING OUTCOMES:

Upon completion of this article, readers will have learned about: (1) the social-communicative profiles of youth with FXS, DS, and ASD, (2) the importance of signaling noncomprehension in response to a confusing message, and (3) the similarities and differences in noncomprehension signaling in youth with FXS (with and without ASD), DS, idiopathic ASD, and TD.
