Autistic differences in the temporal dynamics of social attention / N. HEDGER in Autism, 25-6 (August 2021)
[article]
Titre : Autistic differences in the temporal dynamics of social attention Type de document : Texte imprimé et/ou numérique Auteurs : N. HEDGER, Auteur ; Bhismadev CHAKRABARTI, Auteur Article en page(s) : p.1615-1626 Langues : Anglais (eng) Mots-clés : Adult Attention Autism Spectrum Disorder Autistic Disorder Fixation, Ocular Humans Probability attention autism eye-tracking gaze social attention temporal modelling of interest with respect to the research, authorship, and/or publication of this article. Index. décimale : PER Périodiques Résumé : One behaviour often observed in individuals with autism is that they tend to look less towards social stimuli relative to neurotypical individuals. For instance, many eye-tracking studies have shown that individuals with autism will look less towards people and more towards objects in scenes. However, we currently know very little about how these behaviours change over time. Tracking these moment-to-moment changes in looking behaviour in individuals with autism can more clearly illustrate how they respond to social stimuli. In this study, adults with and without autism were presented with displays of social and non-social stimuli, while looking behaviours were measured by eye-tracking. We found large differences in how the two groups looked towards social stimuli over time. Neurotypical individuals initially showed a high probability of looking towards social stimuli, then a decline in probability, and a subsequent increase in probability after prolonged viewing. By contrast, individuals with autism showed an initial increase in probability, followed by a continuous decline in probability that did not recover. This pattern of results may indicate that individuals with autism exhibit reduced responsivity to the reward value of social stimuli. Moreover, our data suggest that exploring the temporal nature of gaze behaviours can lead to more precise explanatory theories of attention in autism.
