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.

OLDEHINKEL, Auteur Article en page(s) : p.985-987 Langues : Anglais (eng) Mots-clés : Statistical methods probability Bayesian analysis hypothesis testing statistical data interpretation Index. décimale : PER Périodiques Résumé : For many scientists, performing statistical tests has become an almost automated routine. However, p-values are frequently used and interpreted incorrectly; and even when used appropriately, p-values tend to provide answers that do not match researchers' questions and hypotheses well. Bayesian statistics present an elegant and often more suitable alternative. The Bayesian approach has rarely been applied in child psychology and psychiatry research so far, but the development of user-friendly software packages and tutorials has placed it well within reach now. Because Bayesian analyses require a more refined definition of hypothesized probabilities of possible outcomes than the classical approach, going Bayesian may offer the additional benefit of sparkling the development and refinement of theoretical models in our field.
