Attentional biases to faces with direct versus averted gaze in children without and with autism spectrum disorder: A dot-probe paradigm / Wei JING in Research in Autism Spectrum Disorders, 108 (October 2023)
[article]
Titre : Attentional biases to faces with direct versus averted gaze in children without and with autism spectrum disorder: A dot-probe paradigm Type de document : Texte imprimé et/ou numérique Auteurs : Wei JING, Auteur ; Jing WANG, Auteur ; Jinxia FU, Auteur Article en page(s) : p.102233 Mots-clés : Children with ASD Dot-probe paradigms Direct gaze Averted gaze Facial attention Index. décimale : PER Périodiques Résumé : Previous research utilized a variety of paradigms to demonstrate attentional biases to faces with direct versus averted gaze in typical development (TD) and no such bias in autism spectrum disorder (ASD). However, little is known about whether the biases can be observed during automatic processing stages in TD and whether the lack of such bias in ASD is due to passive neglect or active avoidance of direct gaze. Therefore, we employed a dot-probe paradigm and manipulated stimulus onset asynchrony (SOA) to measure response times to probes replacing faces with direct gaze compared to faces with averted gaze in children without and with ASD. There was no evidence of attentional bias in either group when stimuli were presented during the automatic processing stage (200 ms SOA). However, during the controlled processing stage (1000 ms SOA), an attentional bias to faces with direct versus averted gaze was found in control children but not in those with ASD. The results indicate that the facilitation of direct gaze on facial attention occurs during controlled rather than automatic processing stages in TD individuals. In contrast, children with ASD respond indiscriminately to direct and averted gaze during both stages of cognitive processing, supporting the gaze indifference hypothesis. For TD children but not for children with ASD, direct gaze is an adaptively informative or socially salient signal.

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.
