Brain Mechanisms for Processing Direct and Averted Gaze in Individuals with Autism / Naomi PITSKEL in Journal of Autism and Developmental Disorders, 41-12 (December 2011)
[article]
Titre : Brain Mechanisms for Processing Direct and Averted Gaze in Individuals with Autism Type de document : Texte imprimé et/ou numérique Auteurs : Naomi PITSKEL, Auteur ; Danielle Z. BOLLING, Auteur ; Caitlin M. HUDAC, Auteur ; Stephen LANTZ, Auteur ; Nancy J. MINSHEW, Auteur ; Brent C. VANDER WYK, Auteur ; Kevin A. PELPHREY, Auteur Année de publication : 2011 Article en page(s) : p.1686-1693 Langues : Anglais (eng) Mots-clés : Autism Direct gaze Averted gaze Gaze processing Functional magnetic resonance imaging Index. décimale : PER Périodiques Résumé : Prior studies have indicated brain abnormalities underlying social processing in autism, but no fMRI study has specifically addressed the differential processing of direct and averted gaze, a critical social cue. Fifteen adolescents and adults with autism and 14 typically developing comparison participants viewed dynamic virtual-reality videos depicting a simple but realistic social scenario, in which an approaching male figure maintained either direct or averted gaze. Significant group by condition interactions reflecting differential responses to direct versus averted gaze in people with autism relative to typically developing individuals were identified in the right temporoparietal junction, right anterior insula, left lateral occipital cortex, and left dorsolateral prefrontal cortex. Our results provide initial evidence regarding brain mechanisms underlying the processing of gaze direction during simple social encounters, providing new insight into the social deficits in individuals with autism.

Titre : Absence of Preferential Unconscious Processing of Eye Contact in Adolescents With Autism Spectrum Disorder Type de document : Texte imprimé et/ou numérique Auteurs : Hironori AKECHI, Auteur ; Timo STEIN, Auteur ; Atsushi SENJU, Auteur ; Yukiko KIKUCHI, Auteur ; Yoshikuni TOJO, Auteur ; Hiroo OSANAI, Auteur ; Toshikazu HASEGAWA, Auteur Article en page(s) : p.590-597 Langues : Anglais (eng) Mots-clés : eye contact gaze processing autism spectrum disorder unconscious processing Index. décimale : PER Périodiques Résumé : Eye contact plays an essential role in social interaction. Atypical eye contact is a diagnostic and widely reported feature of autism spectrum disorder (ASD). Here, we determined whether altered unconscious visual processing of eye contact might underlie atypical eye contact in ASD. Using continuous flash suppression (CFS), we found that typically developing (TD) adolescents detected faces with a direct gaze faster than faces with an averted gaze, indicating enhanced unconscious processing of eye contact. Critically, adolescents with ASD did not show different durations of perceptual suppression for faces with direct and averted gaze, suggesting that preferential unconscious processing of eye contact is absent in this group. In contrast, in a non-CFS control experiment, both adolescents with ASD and TD adolescents detected faces with a direct gaze faster than those with an averted gaze. Another CFS experiment confirmed that unconscious processing of non-social stimuli is intact for adolescents with ASD. These results suggest that atypical processing of eye contact in individuals with ASD could be related to a weaker initial, unconscious registration of eye contact.
