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)
[article]
Titre : Brief Report: Visual Perception, Task-Induced Pupil Response Trajectories and ASD Features in Children Type de document : Texte imprimé et/ou numérique Auteurs : A. 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.

Titre : The Broader Autism Phenotype and Visual Perception in Children Type de document : Texte imprimé et/ou numérique Auteurs : Antoinette SABATINO-DICRISCIO, Auteur ; V. TROIANI, Auteur Article en page(s) : p.2809-2820 Langues : Anglais (eng) Mots-clés : Broader autism phenotype Children Global-local processing Tvps Visual perception Index. décimale : PER Périodiques Résumé : Atypical visual perception has increasingly been described in individuals with autism spectrum disorders (ASD) and linked to quantitative, autism-like features that are present in children and adults without ASD. We investigated whether individual differences in visual processing skills were related to quantitative measures of autism traits in a pediatric sample with a range of clinical features. Visual processing was comprehensively characterized using the test of visual perceptual skills (TVPS), a standardized test of visual perception with seven subtests that capture a range of visual processing abilities. The TVPS Figure Ground (TVPS-FG) subtest requires an individual to disembed a smaller figure from a larger scene. TVPS-FG subtest scores were positively correlated with children's autism features as measured by a parental report of the Broader Autism Phenotype Questionnaire (BAP-Q). The correlation with BAP-Q was specific to the TVPS-FG subtest, as the other TVPS subtest scores were not significantly related to the BAP-Q. This adds to the growing body of research documenting that atypical visual processing is associated with the autism phenotype and highlights the importance of capturing quantitative traits in heterogeneous developmental brain disorders.
