Reduced social attention in autism is magnified by perceptual load in naturalistic environments / Amanda J. HASKINS in Autism Research, 15-12 (December 2022)
[article]
Titre : Reduced social attention in autism is magnified by perceptual load in naturalistic environments Type de document : Texte imprimé et/ou numérique Auteurs : Amanda J. HASKINS, Auteur ; Jeff MENTCH, Auteur ; Thomas L. BOTCH, Auteur ; Brenda D. GARCIA, Auteur ; Alexandra L. BURROWS, Auteur ; Caroline E. ROBERTSON, Auteur Article en page(s) : p.2310-2323 Langues : Anglais (eng) Mots-clés : Humans Autistic Disorder Autism Spectrum Disorder Cues Attention adults eye movement sensory social cognition Index. décimale : PER Périodiques Résumé : Individuals with autism spectrum conditions (ASC) describe differences in both social cognition and sensory processing, but little is known about the causal relationship between these disparate functional domains. In the present study, we sought to understand how a core characteristic of autism-reduced social attention-is impacted by the complex multisensory signals present in real-world environments. We tested the hypothesis that reductions in social attention associated with autism would be magnified by increasing perceptual load (e.g., motion, multisensory cues). Adult participants (N = 40; 19 ASC) explored a diverse set of 360° real-world scenes in a naturalistic, active viewing paradigm (immersive virtual reality + eyetracking). Across three conditions, we systematically varied perceptual load while holding the social and semantic information present in each scene constant. We demonstrate that reduced social attention is not a static signature of the autistic phenotype. Rather, group differences in social attention emerged with increasing perceptual load in naturalistic environments, and the susceptibility of social attention to perceptual load predicted continuous measures of autistic traits across groups. Crucially, this pattern was specific to the social domain: we did not observe differential impacts of perceptual load on attention directed toward nonsocial semantic (i.e., object, place) information or low-level fixation behavior (i.e., overall fixation frequency or duration). This study provides a direct link between social and sensory processing in autism. Moreover, reduced social attention may be an inaccurate characterization of autism. Instead, our results suggest that social attention in autism is better explained by "social vulnerability," particularly to the perceptual load of real-world environments.
