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 / Shuyuan 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 Auteurs : Shuyuan FENG, Auteur ; Haoyang LU, Auteur ; Quan WANG, Auteur ; Tianbi LI, Auteur ; Jing FANG, Auteur ; Lihan CHEN, Auteur ; Li YI, Auteur Année de publication : 2021 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 / Quan 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 Auteurs : Quan WANG, Auteur ; Daniel J. CAMPBELL, Auteur ; Suzanne L. MACARI, Auteur ; Katarzyna CHAWARSKA, Auteur ; Frederick 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.

Promoting social attention in 3-year-olds with ASD through gaze-contingent eye tracking / Quan WANG in Autism Research, 13-1 (January 2020)  

Public ISBD [article]  inAutism Research > 13-1 (January 2020) . - p.61-73 Titre : Promoting social attention in 3-year-olds with ASD through gaze-contingent eye tracking Type de document : texte imprimé Auteurs : Quan WANG, Auteur ; Carla A. WALL, Auteur ; Erin C. BARNEY, Auteur ; Jessica BRADSHAW, Auteur ; Suzanne L. MACARI, Auteur ; Katarzyna CHAWARSKA, Auteur ; Frederick SHIC, Auteur Article en page(s) : p.61-73 Langues : Anglais (eng) Mots-clés : attention  children  data-driven techniques  developmental psychology  eye movement  intervention early  visual Index. décimale : PER Périodiques Résumé : Young children with autism spectrum disorder (ASD) look less toward faces compared to their non-ASD peers, limiting access to social learning. Currently, no technologies directly target these core social attention difficulties. This study examines the feasibility of automated gaze modification training for improving attention to faces in 3-year-olds with ASD. Using free-viewing data from typically developing (TD) controls (n = 41), we implemented gaze-contingent adaptive cueing to redirect children with ASD toward normative looking patterns during viewing of videos of an actress. Children with ASD were randomly assigned to either (a) an adaptive Cue condition (Cue, n = 16) or (b) a No-Cue condition (No-Cue, n = 19). Performance was examined at baseline, during training, and post-training, and contrasted with TD controls (n = 23). Proportion of time looking at the screen (%Screen) and at actresses' faces (%Face) was analyzed. At Pre-Training, Cue and No-Cue groups did not differ in %Face (P > 0.1). At Post-Training, the Cue group had higher %Face than the No-Cue group (P = 0.015). In the No-Cue group %Face decreased Pre- to Post-Training; no decline was observed in the Cue group. These results suggest gaze-contingent training effectively mitigated decreases of attention toward the face of onscreen social characters in ASD. Additionally, larger training effects were observed in children with lower nonverbal ability, suggesting a gaze-contingent approach may be particularly relevant for children with greater cognitive impairment. This work represents development toward new social attention therapeutic systems that could augment current behavioral interventions. Autism Res 2020, 13: 61-73. (c) 2019 International Society for Autism Research, Wiley Periodicals, Inc. LAY SUMMARY: In this study, we leverage a new technology that combines eye tracking and automatic computer programs to help very young children with ASD look at social information in a more prototypical way. In a randomized controlled trial, we show that the use of this technology prevents the diminishing attention toward social information normally seen in children with ASD over the course of a single experimental session. This work represents development toward new social attention therapeutic systems that could augment current behavioral interventions.
