Social and nonsocial visual prediction errors in autism spectrum disorder / R. K. GREENE in Autism Research, 12-6 (June 2019)
[article]
Titre : Social and nonsocial visual prediction errors in autism spectrum disorder Type de document : Texte imprimé et/ou numérique Auteurs : R. K. GREENE, Auteur ; S. ZHENG, Auteur ; J. L. KINARD, Auteur ; M. G. MOSNER, Auteur ; C. A. WIESEN, Auteur ; D. P. KENNEDY, Auteur ; Gabriel S. DICHTER, Auteur Année de publication : 2019 Article en page(s) : p.878-883 Langues : Anglais (eng) Mots-clés : autism spectrum disorder eye tracking prediction error Index. décimale : PER Périodiques Résumé : Impaired predictive coding has been proposed as a framework to explain discrepancies between expectations and outcomes in autism spectrum disorder (ASD) that may contribute to core symptoms of the disorder. However, no eye tracking study has directly addressed this framework in the context of visual predictions of social and nonsocial stimuli. The current study used eye tracking to examine violations of learned visual associations of both social and nonsocial stimuli. Twenty-six adolescents with ASD and 18 typically developing control (TDC) adolescents completed an outcome expectation eye tracking task in which predictive cues correctly (80% of trials) or incorrectly (20% of trials) indicated the location (left or right) of forthcoming social or nonsocial stimuli. During violation trials, individuals with ASD focused their gaze relatively more often on stimuli presented on locations that violated the learned association and less often on locations that corresponded with the learned association. This finding was not moderated by stimulus type (i.e., social vs. nonsocial). Additionally, participants who looked at incorrectly predicted locations more often had significantly greater ASD symptom severity. These results are consistent with theories that characterize ASD as a disorder of prediction and have potential implications for understanding symptoms related to prediction errors in individuals with ASD. Autism Res 2019, 12: 878-883. (c) 2019 International Society for Autism Research, Wiley Periodicals, Inc. LAY SUMMARY: Individuals with autism spectrum disorder (ASD) exhibit impairments making predictions that may impact learning. In this study, we used eye tracking methodology and found that individuals with ASD were less likely to look at the predicted location when a visual routine was violated. This pattern was evident for both social and nonsocial images and was associated with greater ASD symptom severity. These findings provide additional support for predictive challenges in ASD.

Titre : Visual Search Performance Does Not Relate to Autistic Traits in the General Population Type de document : Texte imprimé et/ou numérique Auteurs : D. LOPEZ PEREZ, Auteur ; D. P. KENNEDY, Auteur ; P. TOMALSKI, Auteur ; Sven BÖLTE, Auteur ; B. D'ONOFRIO, Auteur ; T. FALCK-YTTER, Auteur Article en page(s) : p.2624-2631 Langues : Anglais (eng) Mots-clés : Autism spectrum disorder Eye movements Eye tracking Reaction times Visual search task Index. décimale : PER Périodiques Résumé : Autism spectrum disorder (ASD) is commonly conceived as the extreme end of a continuum. Research suggests that autistic individuals outperform typically developing controls in visual search. Thus, enhanced visual search may represent an adaptive trait associated with ASD. Here, using a large general population sample (N = 608, aged 9-14 years), we tested if higher levels of autistic traits are associated with enhanced visual search. Visual search was evaluated using both manual responses and eye movements, and autistic traits were measured using the Social Responsiveness Scale. Contrary to our hypothesis, no significant relation between autistic traits and visual search were observed. The theoretical implications of these results are discussed.
