However, much of the research having found an alteration in MSI in ASD involved socio-communicative stimuli. The goal of the current study was to investigate MSI abilities in ASD using lower-level stimuli that are not socio-communicative in nature by testing susceptibility to auditory-guided visual illusions. Adolescents and adults with ASD and typically-developing (TD) individuals were shown to have similar susceptibility to a fission illusion. However, the ASD group was significantly more susceptible to the fusion illusion. Results suggest that individuals with ASD demonstrate MSI on the flash-beep illusion task but that their integration of audiovisual sensory information may be less selective than for TD individuals.

Within- and Cross-Modal Integration and Attention in the Autism Spectrum / Genevieve CHARBONNEAU in Journal of Autism and Developmental Disorders, 50-1 (January 2020)  

Public ISBD [article]  inJournal of Autism and Developmental Disorders > 50-1 (January 2020) . - p.87-100 Titre : Within- and Cross-Modal Integration and Attention in the Autism Spectrum Type de document : Texte imprimé et/ou numérique Auteurs : Genevieve CHARBONNEAU, Auteur ; Armando BERTONE, Auteur ; Marie VERONNEAU, Auteur ; Simon GIRARD, Auteur ; Maxime PELLAND, Auteur ; Laurent MOTTRON, Auteur ; Franco LEPORE, Auteur ; Olivier COLLIGNON, Auteur Article en page(s) : p.87-100 Langues : Anglais (eng) Mots-clés : Autism spectrum  Sensory integration  Tactile  Visual Index. décimale : PER Périodiques Résumé : Although impairment in sensory integration is suggested in the autism spectrum (AS), empirical evidences remain equivocal. We assessed the integration of low-level visual and tactile information within and across modalities in AS and typically developing (TD) individuals. TD individuals demonstrated increased redundancy gain for cross-modal relative to double tactile or visual stimulation, while AS individuals showed similar redundancy gain between cross-modal and double tactile conditions. We further observed that violation of the race model inequality for cross-modal conditions was observed over a wider proportion of the reaction times distribution in TD than AS individuals. Importantly, the reduced cross-modal integration in AS individuals was not related to atypical attentional shift between modalities. We conclude that AS individuals displays selective decrease of cross-modal integration of low-level information.
