The current study examined whether increasing visual perceptual load also has less of an effect on auditory awareness in children with ASD. Participants performed either a high- or low load version of a line discrimination task. On a critical trial, an unexpected, task-irrelevant auditory stimulus was played concurrently with the visual stimulus. In contrast to typically developing (TD) children, children with ASD demonstrated similar detection rates across perceptual load conditions, and reported greater awareness than TD children in the high perceptual load condition. These findings suggest an increased perceptual capacity in children with ASD that operates across sensory modalities.

The Effect of Visual Perceptual Load on Auditory Awareness of Social vs. Non-social Stimuli in Individuals with Autism / Julian TILLMANN in Journal of Autism and Developmental Disorders, 51-4 (April 2021)  

Public ISBD [article]  inJournal of Autism and Developmental Disorders > 51-4 (April 2021) . - p.1028-1038 Titre : The Effect of Visual Perceptual Load on Auditory Awareness of Social vs. Non-social Stimuli in Individuals with Autism Type de document : Texte imprimé et/ou numérique Auteurs : Julian TILLMANN, Auteur ; Jyrki TUOMAINEN, Auteur ; John SWETTENHAM, Auteur Article en page(s) : p.1028-1038 Langues : Anglais (eng) Mots-clés : Attention  Auditory awareness  Autism spectrum disorder  Perceptual load  Social stimulus Index. décimale : PER Périodiques Résumé : This study examined the effect of increasing visual perceptual load on auditory awareness for social and non-social stimuli in adolescents with autism spectrum disorder (ASD, n?=?63) and typically developing (TD, n?=?62) adolescents. Using an inattentional deafness paradigm, a socially meaningful ('Hi') or a non-social (neutral tone) critical stimulus (CS) was unexpectedly presented under high and low load. For the social CS both groups continued to show high awareness rates as load increased. Awareness rates for the non-social stimulus were reduced when load increased for the TD, but not the ASD group. The findings indicate enhanced capacity for non-social stimuli in ASD compared to TD, and a special attentional status for social stimuli in the TD group.
