Title

Multisensory Speech Perception in Children with Autism Spectrum Disorders

Abstract

This study examined unisensory and multisensory speech perception in 8–17 year old children with autism spectrum disorders (ASD) and typically developing controls matched on chronological age, sex, and IQ. Consonant–vowel syllables were presented in visual only, auditory only, matched audiovisual, and mismatched audiovisual (“McGurk”) conditions. Participants with ASD displayed deficits in visual only and matched audiovisual speech perception. Additionally, children with ASD reported a visual influence on heard speech in response to mismatched audiovisual syllables over a wider window of time relative to controls. Correlational analyses revealed associations between multisensory speech perception, communicative characteristics, and responses to sensory stimuli in ASD. Results suggest atypical speech perception is linked to broader behavioral characteristics of ASD.
