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)
[article]
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.

Titre : Brief Report: Infants Developing with ASD Show a Unique Developmental Pattern of Facial Feature Scanning Type de document : Texte imprimé et/ou numérique Auteurs : Melissa D. RUTHERFORD, Auteur ; Jennifer A. WALSH, Auteur ; Vivian LEE, Auteur Année de publication : 2015 Article en page(s) : p.2618-2623 Langues : Anglais (eng) Mots-clés : Face scanning Autism Language development Index. décimale : PER Périodiques Résumé : Infants are interested in eyes, but look preferentially at mouths toward the end of the first year, when word learning begins. Language delays are characteristic of children developing with autism spectrum disorder (ASD). We measured how infants at risk for ASD, control infants, and infants who later reached ASD criterion scanned facial features. Development differed across groups. The preference for the eyes region decreased with age in infants who were at risk of ASD. For the control group the change in feature preference was marginally significant for a quadratic model, reflecting a decrease in the preference for eyes at 9 months followed by a recovery. The infants who later reached ASD criterion did not show a significant change across time.

While face scanning is a dynamic process, the way autistic children distribute their attention between the eyes and mouth of their interlocutor is usually analyzed by averaging the proportion of time spent looking either on the eyes or the mouth over the whole duration of stimulus presentation. Method In this study, instead, we focused on the temporal distribution of visual attention between the eyes and mouth of adult faces in 58 autistic and 61 typically developing (TD) children. Participants? eye movements were recorded as they were freely watching videos of faces of silent and speaking adults. We explored attention to the eyes and mouth with fine-grained analyses of the temporal trajectory of fixations on the two regions using generalized additive mixed effects models. Results These analyses revealed that both groups started their observation of speaking faces on the eyes and shifted to the mouth as the actor started speaking. However, TD, but not autistic children then slowly shifted their attention back to the eyes. Conclusions Rigorous analyses of how autistic children modulate their visual attention between key social features of the face over time may provide more accurate descriptions of their face scanning abilities.

However, there has been considerable controversy regarding whether ASD individuals also scan faces differently from typical adults. Here we compared ASD individuals' face-scanning patterns with those of typically developing (TD) controls and intellectually disabled (ID) but non-ASD individuals with the use of an eye tracker and multiple approaches to analyze eye-tracking data. First, we analyzed the eye movement data with a traditional approach, measuring fixation duration on each area of interest within the face. We found that compared with TD and ID individuals, ASD individuals looked significantly shorter at the right eye. Second, we used a data-driven method that analyzes fixations on each pixel of the face stimulus and found that individuals with ASD looked more at the central nasal area than TD and ID individuals. Third, we used a novel saccade path analysis that measures frequencies of saccades between major face areas. We found that ASD individuals scanned less often between core facial features than TD individuals but did not differ from ID individuals. Findings from the multi-method approaches show that individuals with ASD appear not to have a pervasive ASD-specific atypicality in visual attention toward the face. The ASD-specific atypical face-scanning patterns were shown to be limited to fixations on the eyes and nose.
