MONGILLO, Auteur ; Alice S. CARTER, Auteur ; Robert T. SCHULTZ, Auteur ; Julia R. IRWIN, Auteur ; D.H. WHALEN, Auteur ; Cheryl KLAIMAN, Auteur Année de publication : 2008 Article en page(s) : p.1349-1358 Langues : Anglais (eng) Mots-clés : Audiovisual-processing Visual-influence McGurk-effect Index. décimale : PER Périodiques Résumé : Fifteen children with autism spectrum disorders (ASD) and twenty-one children without ASD completed six perceptual tasks designed to characterize the nature of the audiovisual processing difficulties experienced by children with ASD. Children with ASD scored significantly lower than children without ASD on audiovisual tasks involving human faces and voices, but scored similarly to children without ASD on audiovisual tasks involving nonhuman stimuli (bouncing balls). Results suggest that children with ASD may use visual information for speech differently from children without ASD. Exploratory results support an inverse association between audiovisual speech processing capacities and social impairment in children with ASD.

Audiovisual Speech Perception in Children with Autism Spectrum Disorders: Evidence from Visual Phonemic Restoration / Julia R. IRWIN in Journal of Autism and Developmental Disorders, 52-1 (January 2022)  

Public ISBD [article]  inJournal of Autism and Developmental Disorders > 52-1 (January 2022) . - p.28-37 Titre : Audiovisual Speech Perception in Children with Autism Spectrum Disorders: Evidence from Visual Phonemic Restoration Type de document : texte imprimé Auteurs : Julia R. IRWIN, Auteur ; Trey AVERY, Auteur ; Daniel KLEINMAN, Auteur ; Nicole LANDI, Auteur Article en page(s) : p.28-37 Langues : Anglais (eng) Mots-clés : Auditory Perception  Autism Spectrum Disorder  Child  Cues  Evoked Potentials  Humans  Speech  Speech Perception  Visual Perception  Audiovisual  Autism  Phonemic restoration Index. décimale : PER Périodiques Résumé : Children with autism spectrum disorders have been reported to be less influenced by a speaker's face during speech perception than those with typically development. To more closely examine these reported differences, a novel visual phonemic restoration paradigm was used to assess neural signatures (event-related potentials [ERPs]) of audiovisual processing in typically developing children and in children with autism spectrum disorder. Video of a speaker saying the syllable /ba/ was paired with (1) a synthesized /ba/ or (2) a synthesized syllable derived from /ba/ in which auditory cues for the consonant were substantially weakened, thereby sounding more like /a/. The auditory stimuli are easily discriminable; however, in the context of a visual /ba/, the auditory /a/ is typically perceived as /ba/, producing a visual phonemic restoration. Only children with ASD showed a large /ba/-/a/ discrimination response in the presence of a speaker producing /ba/, suggesting reduced influence of visual speech.
