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.

Staged Audiovisual Speech Integration and Altered Early-Stage Audiovisual Processing in Autistic Children: An EEG Investigation / Shuyuan FENG in Autism Research, 19-7 (July 2026)  

Public ISBD [article]  inAutism Research > 19-7 (July 2026) . - p.e70273 Titre : Staged Audiovisual Speech Integration and Altered Early-Stage Audiovisual Processing in Autistic Children: An EEG Investigation Type de document : texte imprimé Auteurs : Shuyuan FENG, Auteur ; Baolin LI, Auteur ; Wei NI, Auteur ; Sio Pan HOI, Auteur ; Xue LI, Auteur ; Juan ZHANG, Auteur ; Qiandong WANG, Auteur ; Lihan CHEN, Auteur ; Li YI, Auteur Article en page(s) : p.e70273 Langues : Anglais (eng) Mots-clés : audiovisual incongruence  audiovisual speech integration  autism  EEG  McGurk effect Index. décimale : PER Périodiques Résumé : ABSTRACT Autistic children exhibit difficulties in audiovisual speech integration, which are associated with their social communication challenges. The neural mechanism underlying audiovisual speech integration difficulties in autism remains unclear. We recruited 19 neurotypical (NT) children and 29 autistic children. We recorded their behavioral responses and Electroencephalography (EEG) signals to audiovisual congruent syllables, and incongruent syllables that could evoke audiovisual speech integration (i.e., McGurk effect). For the EEG analysis, we further classified autistic children into the autistic McGurk group and the autistic non-McGurk group based on their strength of audiovisual speech integration. Behaviorally, we found reduced audiovisual speech integration in autistic children. At the neural level, we found that: (1) NT children showed an early stage audiovisual processing (indexed by the N1 amplitude), which was altered in two autistic groups; (2) all three groups exhibited a successful audiovisual incongruence detection (i.e., phonological Mismatch Negativity, pMMN); (3) NT and autistic McGurk groups could successfully resolve the audiovisual incongruence (indexed by the restoration of pMMN), but the autistic non-McGurk group could not (indexed by the sustained negative amplitude). Furthermore, we found a distinct temporal decoding pattern between non-McGurk and congruent trials across groups: both NT and autistic McGurk groups exhibited early EEG decoding, whereas the autistic non-McGurk group demonstrated successful decoding during late processing stages. Audiovisual speech integration entails a three-stage process in NT children: early audiovisual processing, audiovisual incongruence detection, and audiovisual incongruence resolution. The altered early-stage processing was possibly the neural mechanism underlying the reduced audiovisual speech integration in autistic children.
