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.

Heterogeneity of Visual Preferences for Biological and Repetitive Movements in Children With Autism Spectrum Disorder / Tianbi LI in Autism Research, 14-1 (January 2021)  

Public ISBD [article]  inAutism Research > 14-1 (January 2021) . - p.102-111 Titre : Heterogeneity of Visual Preferences for Biological and Repetitive Movements in Children With Autism Spectrum Disorder Type de document : texte imprimé Auteurs : Tianbi LI, Auteur ; Yewei LI, Auteur ; Yixiao HU, Auteur ; Yuyin WANG, Auteur ; Cheuk Man LAM, Auteur ; Wei NI, Auteur ; Xueqin WANG, Auteur ; Li YI, Auteur Article en page(s) : p.102-111 Langues : Anglais (eng) Mots-clés : autism spectrum disorder  eye movement  heterogeneity  repetitive behavior  visual biological movement  visual preference Index. décimale : PER Périodiques Résumé : Previous studies have repeatedly reported atypical visual preferences to repetitive movements and deficient perception of biological movements in individuals with autism spectrum disorder (ASD). However, limited research has investigated the heterogeneity of the visual preferences in individuals with ASD. In the current study, we explored the visual preferences to different movement types (repetitive, biological, and random) in children with ASD using a paired preferential looking paradigm. Thirty-nine children with ASD and 37 typically developing (TD) children participated in our study, with their eye movements recorded as the index of visual preferences. We examined the differences of visual preferences between the ASD and TD group, and the heterogeneity of visual preferences within the ASD group. We found group differences between children with ASD and TD children: Overall, the ASD group preferred repetitive movements while the TD group preferred biological movements. We also detected heterogeneity of visual preferences within the ASD group: Although the majority of children with ASD preferred repetitive movements as previous studies reported, 9 out of 39 children with ASD preferred biological movements similarly as their TD peers. Moreover, the visual preference patterns were correlated with autistic symptoms, especially the socio-communicative impairments. Our study provided evidence of heterogeneity of visual attention and main visual preference to repetitive movements in children with ASD. The findings add to the body of literature of the heterogeneous behavioral symptoms and the atypical visual preferences in individuals with ASD. LAY SUMMARY: The current study examined visual preferences to biological, repetitive, and random movements in children with Autism Spectrum Disorder (ASD). We showed a pair of two videos representing two types of movements (random, repetitive, or biological movements) to children with ASD and typically developing children. We found the main visual preferences for repetitive movements and heterogeneity of visual attention within the ASD group. Our findings provide theoretical and methodological implications for future study of the heterogeneity in the ASD population.

Orienting to and away from the eyes in infants at high likelihood for autism when scanning faces / Qiandong WANG ; Ying HAN ; Yixiao HU ; Xue LI ; Jing LIU ; Hui FANG ; Tianbi LI ; Yanmei CHANG ; Li YI in Autism Research, 18-1 (January 2025)  

Public ISBD [article]  inAutism Research > 18-1 (January 2025) . - p.166-178 Titre : Orienting to and away from the eyes in infants at high likelihood for autism when scanning faces : Autism Research Type de document : texte imprimé Auteurs : Qiandong WANG, Auteur ; Ying HAN, Auteur ; Yixiao HU, Auteur ; Xue LI, Auteur ; Jing LIU, Auteur ; Hui FANG, Auteur ; Tianbi LI, Auteur ; Yanmei CHANG, Auteur ; Li YI, Auteur Article en page(s) : p.166-178 Langues : Anglais (eng) Mots-clés : autism  eye movement  face processing  infants  visual attention Index. décimale : PER Périodiques Résumé : Abstract This study employed eye-tracking technology to investigate the mechanisms underlying reduced gaze towards the eyes in infants at high likelihood (HL) for autism, specifically examining whether it results from avoidance triggered by heightened arousal when looking at the eyes or due to indifference to the eyes (i.e., unwilling to orient to the eyes). Infants at HL for autism and typically developing (TD) infants aged within 24 months were tested. In the experiment, participants' gaze was initially guided to the eye or mouth region immediately before the onset of the face. Latency to orient away from the guided regions, latency to orient to the eyes, and the location of the secondary fixation following the onset of the face were measured. The results showed that: (1) The HL infants looked less at eyes than TD infants; (2) Compared with TD infants, HL infants oriented towards eyes more slowly after being guided to the mouth; (3) After being guided to the eyes, HL infants' secondary fixation fell less in the eye region, and their latency to orient away from the eyes was also tended to be shorter. These results suggest that reduced eye-looking time was presented in HL infants, which was further explained by both eye avoidance and indifference to the eyes. Our study contributes theoretically to understanding the atypical face scanning pattern in autistic people and its related underlying mechanisms. Furthermore, our study provides important insights into the development of early screening tools and intervention protocols for autistic people.
