Saccadic eye movements in adults with high-functioning autism spectrum disorder / Tiziana ZALLA in Autism, 22-2 (February 2018)  

Public ISBD [article]  inAutism > 22-2 (February 2018) . - p.195-204 Titre : Saccadic eye movements in adults with high-functioning autism spectrum disorder Type de document : texte imprimé Auteurs : Tiziana ZALLA, Auteur ; Magali SEASSAU, Auteur ; Fabienne CAZALIS, Auteur ; Doriane GRAS, Auteur ; Marion LEBOYER, Auteur Année de publication : 2018 Article en page(s) : p.195-204 Langues : Anglais (eng) Mots-clés : brainstem,cerebellum,eye tracking,Gap/Overlap,saccade,sensorimotor Index. décimale : PER Périodiques Résumé : In this study, we examined the accuracy and dynamics of visually guided saccades in 20 adults with autism spectrum disorder, as compared to 20 typically developed adults using the Step/Overlap/Gap paradigms. Performances in participants with autistic spectrum disorder were characterized by preserved Gap/Overlap effect, but reduced gain and peak velocity, as well as a greater trial-to-trial variability in task performance, as compared to the control group. While visual orienting and attentional engagement were relatively preserved in individuals with autistic spectrum disorder, overall these findings provide evidence that abnormal oculomotor behavior in autistic spectrum disorder reflects an altered sensorimotor control due to cerebellar abnormalities, rather than a deficit in the volitional control of eye movements. This study contributes to a growing body of evidence implicating this structure in the physiopathology of autism.

Trustworthiness and Dominance Personality Traits' Judgments in Adults with Autism Spectrum Disorder / Alice LATIMIER in Journal of Autism and Developmental Disorders, 49-11 (November 2019)  

Public ISBD [article]  inJournal of Autism and Developmental Disorders > 49-11 (November 2019) . - p.4535-4546 Titre : Trustworthiness and Dominance Personality Traits' Judgments in Adults with Autism Spectrum Disorder Type de document : texte imprimé Auteurs : Alice LATIMIER, Auteur ; Klara KOVARSKI, Auteur ; Hugo PEYRE, Auteur ; Laura Gabriela FERNANDEZ, Auteur ; Doriane GRAS, Auteur ; Marion LEBOYER, Auteur ; Tiziana ZALLA, Auteur Article en page(s) : p.4535-4546 Langues : Anglais (eng) Mots-clés : Asd  Eye-tracking  Face processing  Personality traits Index. décimale : PER Périodiques Résumé : Autism Spectrum Disorder (ASD) is characterized by impairments in social functioning, communication, and by the presence of repetitive behaviours and restricted interests. Abnormal processing of faces has also been described as a neuropsychological feature of ASD. We investigated the ability to judge two personality traits in adults with ASD in comparison to typically developed adults (TD). We used an eye tracking device to investigate the exploration of faces when participants judged the degree of trustworthiness and dominance of synthetic faces. In sum, we found that adults with ASD were as capable as TD adults to judge personality traits of face trustworthiness and dominance, which relied on similar exploration of the synthetic faces in the two populations.
