Visual Exploration in Autism Spectrum Disorder: Exploring Age Differences and Dynamic Features Using Recurrence Quantification Analysis / N. V. MANYAKOV in Autism Research, 11-11 (November 2018)  

Public ISBD [article]  inAutism Research > 11-11 (November 2018) . - p.1554-1566 Titre : Visual Exploration in Autism Spectrum Disorder: Exploring Age Differences and Dynamic Features Using Recurrence Quantification Analysis Type de document : Texte imprimé et/ou numérique Auteurs : N. V. MANYAKOV, Auteur ; Abigail BANGERTER, Auteur ; Meenakshi CHATTERJEE, Auteur ; L. MASON, Auteur ; S. NESS, Auteur ; D. LEWIN, Auteur ; A. SKALKIN, Auteur ; Matthew A. BOICE, Auteur ; M. S. GOODWIN, Auteur ; G. DAWSON, Auteur ; R. HENDREN, Auteur ; B. LEVENTHAL, Auteur ; F.

This includes preference for certain nonsocial objects, heightened attention to detail, and more difficulty with attention shifting and disengagement, which may be associated with restricted and repetitive behaviors. This study utilized a visual exploration task and replicates findings of reduced number of objects explored and increased fixation duration on high autism interest objects in a large sample of individuals with autism spectrum disorder (n = 129, age 6-54 years) in comparison with a typically developing group. These findings correlated with parent-reported repetitive behaviors. Additionally, we applied recurrent quantification analysis to enable identification of new eye-tracking features, which accounted for temporal and spatial differences in viewing patterns. These new features were found to discriminate between autism spectrum disorder and typically developing groups and were correlated with parent-reported repetitive behaviors. Original and novel eye-tracking features identified by recurrent quantification analysis differed in their relationships to reported behaviors and were dependent on age. Trial Registration: NCT02299700. Autism Research 2018, 11: 1554-1566. (c) 2018 International Society for Autism Research, Wiley Periodicals, Inc. LAY SUMMARY: Using eye-tracking technology and a visual exploration task, we showed that people with autism spectrum disorder (ASD) spend more time looking at particular kinds of objects, like trains and clocks, and look at fewer objects overall than people without ASD. Where people look and the order in which they look at objects were related to the restricted and repetitive behaviors reported by parents. Eye-tracking may be a useful addition to parent reports for measuring changes in behavior in individuals with ASD.

Perspective influences eye movements during real-life conversation: Mentalising about self versus others in autism / Mahsa BARZY in Autism, 24-8 (November 2020)  

Public ISBD [article]  inAutism > 24-8 (November 2020) . - p.2153-2165 Titre : Perspective influences eye movements during real-life conversation: Mentalising about self versus others in autism Type de document : Texte imprimé et/ou numérique Auteurs : Mahsa BARZY, Auteur ; Heather J. FERGUSON, Auteur ; David M. WILLIAMS, Auteur Article en page(s) : p.2153-2165 Langues : Anglais (eng) Mots-clés : *Autism  *eye-tracking  *perspective taking  *real-life social interactions  *topic of conversation  of interest with respect to the research, authorship, and/or publication of this  article. Index. décimale : PER Périodiques Résumé : Previous lab-based studies suggest that autistic individuals are less attentive to social aspects of their environment. In our study, we recorded the eye movements of autistic and typically developing adults while they engaged in a real-life social interaction with a partner. Results showed that autistic adults were less likely than typically developing adults to look at the experimenter's face, and instead were more likely to look at the background. Moreover, the perspective that was adopted in the conversation (talking about self versus others) modulated the patterns of eye movements in autistic and non-autistic adults. Overall, people spent less time looking at their conversation partner's eyes and face and more time looking at the background, when talking about an unfamiliar other compared to when talking about themselves. This pattern was magnified among autistic adults. We conclude that allocating attention to social information during conversation is cognitively effortful, but this can be mitigated when talking about a topic that is familiar to them.
