Uh, Um, and Autism: Filler Disfluencies as Pragmatic Markers in Adolescents with Optimal Outcomes from Autism Spectrum Disorder
AbstractFiller disfluencies uh and um are thought to serve distinct discourse functions. We examined fillers in spontaneous speech by youth with autism spectrum disorder (ASD) who struggle with pragmatic language, and by youth with ASD who have achieved an 'optimal outcome' (OO) as well as in peers with typical development (TD) While uh rates did not differ, participants with ASD produced um less frequently than OO or TD groups. Um rate was associated with autism symptom severity, but not executive function or language abilities, suggesting that um serves a pragmatic, listener oriented function. Moreover, in contrast to minimal production in ASD, the typical OO um production substantiates the normalization of subtle social communication in this population.
