Using Navon stimuli in a task-switching paradigm, participants were instructed to identify global or local information based on a cue. Multiple pupil response trajectories across conditions were identified. We combined trajectory patterns for global and local conditions and used data-driven methods to identify three distinct pupil trajectory sub-groups. We report higher scores on quantitative measures of autism features in individuals who demonstrated an increased change in pupil diameter across both conditions. Results demonstrate the use of individualized pupil response trajectories in order to quantitatively characterize visual perception associated with the broader autism phenotype (BAP).

Brief Report: Visual Perception, Task-Induced Pupil Response Trajectories and ASD Features in Children / A. S. DICRISCIO in Journal of Autism and Developmental Disorders, 49-7 (July 2019)

S. DICRISCIO, Auteur ; Y. HU, Auteur ; V. TROIANI, Auteur Article en page(s) : p.3016-3030 Langues : Anglais (eng) Mots-clés : Autism  Eye tracking  Global-local processing  Perception  Pupillometry Index. décimale : PER Périodiques Résumé : We applied a trajectory-based analysis to eye tracking data in order to quantify individualized patterns of pupil response in the context of global-local processing that may be associated with autism spectrum disorder (ASD) features. Multiple pupil response trajectories across both global and local conditions were identified. Using the combined trajectory patterns for global and local conditions for each individual, we were able to identify three groups based on trajectory group membership that were thought to reflect perceptual strategy. Results indicated that the proportion of children with ASD was significantly greater in the group demonstrating a local-focus response. This research presents a novel analytic approach to the objective characterization of individualized pupil response patterns that are associated with ASD features.

Children with Autism Spectrum Disorder Prefer Looking at Repetitive Movements in a Preferential Looking Paradigm / Q. WANG in Journal of Autism and Developmental Disorders, 48-8 (August 2018)  

Public ISBD [article]  inJournal of Autism and Developmental Disorders > 48-8 (August 2018) . - p.2821-2831 Titre : Children with Autism Spectrum Disorder Prefer Looking at Repetitive Movements in a Preferential Looking Paradigm Type de document : Texte imprimé et/ou numérique Auteurs : Q. WANG, Auteur ; Y. HU, Auteur ; D. SHI, Auteur ; Y. ZHANG, Auteur ; X. ZOU, Auteur ; S. LI, Auteur ; F. FANG, Auteur ; L. YI, Auteur Article en page(s) : p.2821-2831 Langues : Anglais (eng) Mots-clés : Autism spectrum disorder  Eye movement  Repetitive behavior  Visual preference  Visual repetitive movement Index. décimale : PER Périodiques Résumé : The present study aimed to investigate the visual preference for repetitive movements in children with autism spectrum disorder (ASD). Young children with ASD and typically-developing (TD) children were presented simultaneously with cartoons depicting repetitive and random movements respectively, while their eye-movements were recorded. We found that: (1) the children with ASD spent more time fixating on the repetitive movements than the random movements, whereas the TD children showed no preference for either type of movements; (2) the children's preference for the repetitive movements was correlated with the parent reports of their repetitive behaviors. Our findings show a promise in using the preferential looking as a potential indicator for the repetitive behaviors and aiding early screening of ASD in future investigations.
