Young children with ASD and typically-developing (TD) children were presented simultaneously with cartoons depicting repetitive and random movements respectively, while their eye-movements were recorded. We found that: (1) the children with ASD spent more time fixating on the repetitive movements than the random movements, whereas the TD children showed no preference for either type of movements; (2) the children's preference for the repetitive movements was correlated with the parent reports of their repetitive behaviors. Our findings show a promise in using the preferential looking as a potential indicator for the repetitive behaviors and aiding early screening of ASD in future investigations.

Face-viewing patterns predict audiovisual speech integration in autistic children / S. FENG in Autism Research, 14-12 (December 2021)  

Public ISBD [article]  inAutism Research > 14-12 (December 2021) . - p.2592-2602 Titre : Face-viewing patterns predict audiovisual speech integration in autistic children Type de document : Texte imprimé et/ou numérique Auteurs : S. FENG, Auteur ; H. LU, Auteur ; Q. WANG, Auteur ; T. LI, Auteur ; J. FANG, Auteur ; L. CHEN, Auteur ; L. YI, Auteur Article en page(s) : p.2592-2602 Langues : Anglais (eng) Mots-clés : Acoustic Stimulation  Autism Spectrum Disorder/complications  Autistic Disorder/complications  Child  Child, Preschool  Female  Humans  Mouth  Speech  Speech Perception  Visual Perception  McGurk effect  atypical face-viewing patterns  audiovisual speech integration  autistic children  eye movements Index. décimale : PER Périodiques Résumé : Autistic children show audiovisual speech integration deficits, though the underlying mechanisms remain unclear. The present study examined how audiovisual speech integration deficits in autistic children could be affected by their looking patterns. We measured audiovisual speech integration in 26 autistic children and 26 typically developing (TD) children (4- to 7-year-old) employing the McGurk task (a videotaped speaker uttering phonemes with her eyes open or closed) and tracked their eye movements. We found that, compared with TD children, autistic children showed weaker audiovisual speech integration (i.e., the McGurk effect) in the open-eyes condition and similar audiovisual speech integration in the closed-eyes condition. Autistic children viewed the speaker's mouth less in non-McGurk trials than in McGurk trials in both conditions. Importantly, autistic children's weaker audiovisual speech integration could be predicted by their reduced mouth-looking time. The present study indicated that atypical face-viewing patterns could serve as one of the cognitive mechanisms of audiovisual speech integration deficits in autistic children. LAY SUMMARY: McGurk effect occurs when the visual part of a phoneme (e.g., "ga") and the auditory part of another phoneme (e.g., "ba") uttered by a speaker were integrated into a fused perception (e.g., "da"). The present study examined how McGurk effect in autistic children could be affected by their looking patterns for the speaker's face. We found that less looking time for the speaker's mouth in autistic children could predict weaker McGurk effect. As McGurk effect manifests audiovisual speech integration, our findings imply that we could improve audiovisual speech integration in autistic children by directing them to look at the speaker's mouth in future intervention.

Operationalizing atypical gaze in toddlers with autism spectrum disorders: a cohesion-based approach / Q. WANG in Molecular Autism, 9 (2018)  

Public ISBD [article]  inMolecular Autism > 9 (2018) . - 25p. Titre : Operationalizing atypical gaze in toddlers with autism spectrum disorders: a cohesion-based approach Type de document : Texte imprimé et/ou numérique Auteurs : Q. WANG, Auteur ; Daniel J. CAMPBELL, Auteur ; S. L. MACARI, Auteur ; Katarzyna CHAWARSKA, Auteur ; F. SHIC, Auteur Article en page(s) : 25p. Langues : Anglais (eng) Mots-clés : Attention  Autism Spectrum Disorder/diagnosis/physiopathology  Case-Control Studies  Child, Preschool  Female  Fixation, Ocular  Humans  Infant  Male  Social Behavior  Visual Perception  asd  Attentional synchrony  Atypicality  Autism  Cohesion  Eye tracking  Visual attention Index. décimale : PER Périodiques Résumé : Background: Multiple eye-tracking studies have highlighted the "atypical" nature of social attention in autism. However, it is unclear how "atypical" or "typical" should be quantified. Methods: We developed a method for identifying moments when members of a group looked at similar places (High-Cohesion Time Frames; HCTFs). We defined typicality as the proximity of gaze points to typically developing (TD) gaze points during TD HCTFs. Comparing toddlers with ASD (n = 112) to developmentally delayed (DD, n = 36) and TD (n = 163) toddlers during a video with Dyadic Bid, Sandwich-Making, Joint Attention, and Animated Toys conditions, we examined (a) individual typicality scores, (b) the relationship between typicality and symptom severity, and (c) HCTF distributions associated with each diagnostic group. Results: The ASD group had lower gaze typicality scores compared to the TD and DD groups in the Dyadic Bid and Sandwich-Making conditions but not during Animated Toys. The DD and TD groups did not differ in any condition. Correlational analyses indicated that higher typicality scores were associated with increased looking at pre-planned locations of the scene indexed by each experimental condition. In the ASD group, lower gaze typicality was associated with more severe autism symptoms. Examining ASD HCTFs, the gaze of toddlers with ASD was least cohesive during Dyadic Bid and most cohesive during Animated Toys. Conclusion: In contrast to non-ASD groups, toddlers with ASD show high cohesion during salient nonsocial events, suggesting that consistency in looking strategies may depend more on perceptual features. These findings are consequential for understanding individual differences in visual attention in ASD and for the design of more sensitive biomarker tasks for stratification, between-group differentiation, and measuring response to treatment.

Social synchronization during joint attention in children with autism spectrum disorder / Q. LIU in Autism Research, 14-10 (October 2021)  

Public ISBD [article]  inAutism Research > 14-10 (October 2021) . - p.2120-2130 Titre : Social synchronization during joint attention in children with autism spectrum disorder Type de document : Texte imprimé et/ou numérique Auteurs : Q.

Forty-one children aged 5 to 8 with ASD and 43 typically developing (TD) children watched a video to complete the response to joint attention (RJA) tasks, during which their gaze data were collected. The synchronization of gaze-shift behaviors between children and the female model in the video was measured with the cross-recurrence quantification analysis (CRQA). Ultimately, we discovered that children with ASD had the ability to synchronize their gaze shifts with the female model in the video during RJA tasks. Compared to the TD children, they displayed lower levels of synchronization and longer latency in this synchronized behavior. These findings provide a new avenue to deepen our understanding of the impairments of social interaction in children with ASD. Notably, the analytic method can be further applied to explore the social synchronization of numerous other social interactive behaviors in ASD. LAY SUMMARY: This study explored how autistic children synchronized their gazed shifts with others' gaze cues during joint attention. We found that compared to typical children, autistic children synchronized their gazed shifts less and needed more time to follow others' gaze. These findings provide a new avenue to deepen our understanding of the impairments of social interaction in children with ASD.
