However, most eye-tracking evidence regarding this impairment has been derived from passive viewing tasks. Here, we compared the passive viewing of faces with an active task involving face identification with morphing faces. While typical controls prioritized the eyes over other facial features regardless of viewing condition, autistic children exhibited reduced eye-looking in passive viewing, but displayed increased attention allocation to the eyes when instructed to identify faces. The proportional eye-looking in ASD during facial recognition was negatively related to the autism symptoms severity. These findings provide evidence regarding the specific situations in which diminished eye-looking may rise in young ASD children.

Orientation to and processing of social stimuli under normal and competitive conditions in children with autism spectrum disorder / Xueke WANG in Research in Autism Spectrum Disorders, 78 (October 2020)  

Public ISBD [article]  inResearch in Autism Spectrum Disorders > 78 (October 2020) . - 101614 Titre : Orientation to and processing of social stimuli under normal and competitive conditions in children with autism spectrum disorder Type de document : Texte imprimé et/ou numérique Auteurs : Xueke WANG, Auteur ; Lu CHEN, Auteur ; Peiwei LIU, Auteur ; Rebecca J. POLK, Auteur ; Tingyong FENG, Auteur Article en page(s) : 101614 Langues : Anglais (eng) Mots-clés : Autism  Social attention  Orientation ability  Processing ability  Circumscribed interests Index. décimale : PER Périodiques Résumé : Background Autism spectrum disorder (ASD) is a complex neurodevelopment disorder characterized by early specific impairments in social attention. However, the abnormality of orientation and processing ability in social attention is still unclear in children with ASD. Method To address this question, we designed two viewing tasks including a background search task (normal social attention condition) and a paired preference task (competitive social attention condition) to explore the social attention in children with ASD. Eye-tracking technology was applied to measure the ability of ASD children to orient towards and process social stimuli under normal and competitive task conditions. Results The results indicated that the initial orientation ability of social attention in children with ASD was normal, but the subsequent processing ability was impaired under both normal and competitive conditions. Specifically as follows: ASD groups, compared with controls groups, had similar time to first fixation to social stimuli but less fixation duration to social stimuli. More importantly, severity of symptoms in ASD children was negatively correlated with the fixation duration to social stimuli. Furthermore, both ASD and TD children preferred to orient and process stimuli related to circumscribed interests (CI), but ASD children had difficulty distinguishing between social and non-CI stimuli under competitive condition. Conclusion These findings suggest that the abnormality in subsequent processing of social stimuli could serve as a key role in social attention impairments, which may provide a new perspective for early identification and intervention training.

Visual scanning and recognition of ambiguous faces in children with autism: The effects of morphing levels and facial identities / Yige WANG in Research in Autism Spectrum Disorders, 92 (April 2022)  

Public ISBD [article]  inResearch in Autism Spectrum Disorders > 92 (April 2022) . - 101931 Titre : Visual scanning and recognition of ambiguous faces in children with autism: The effects of morphing levels and facial identities Type de document : Texte imprimé et/ou numérique Auteurs : Yige WANG, Auteur ; Zhi SHAO, Auteur ; Libin ZHANG, Auteur ; Tingyong FENG, Auteur Article en page(s) : 101931 Langues : Anglais (eng) Mots-clés : Autism spectrum disorder  Face recognition  Eye fixation  Face scanning  Familiarity Index. décimale : PER Périodiques Résumé : Background and aim Prior work on face processing in children with autism spectrum disorder (ASD) has mainly focused on the investigation of unfamiliar faces. The present study aimed to extend earlier research by the inclusion of the different faces with varying levels of perceptual difficulty. Methods We employed eye-tracking and morphing techniques to measure face recognition involving identification of face morphs and to record eye movements during the task. Three groups of children participated in the study, comprising 24 with ASD (aged from 4 to 7 years), 25 verbal IQ (VQ)-matched typical developing (TD) controls (aged from 3 to 4 years), and 25 chronological age (CA)-matched TD controls (aged from 4 to 6 years). Results The group-difference was specific for morphed unknown faces – ASD children had a decreased judgement of unknown faces and showed a lower specificity. Concurrent eye-tracking further provided mechanistic insights: the ASD group exhibited a significant reduction in eye-region fixation when recognizing ambiguous unknown faces, relative to both TD groups. Conclusion The current study provides evidence of a selective difficulty in the identification of unknown faces in ASD when the perceptual demand increased, without atypicality in self and familiar face processing. Reduced attention and social interest may be responsible for difficulties in response to stranger faces in young ASD children, rather than a consequence of inability.
