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 Auteurs : S.

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.

The Perceived Social Context Modulates Rule Learning in Autism / Haoyang LU in Journal of Autism and Developmental Disorders, 49-11 (November 2019)  

Public ISBD [article]  inJournal of Autism and Developmental Disorders > 49-11 (November 2019) . - p.4698-4706 Titre : The Perceived Social Context Modulates Rule Learning in Autism Type de document : texte imprimé Auteurs : Haoyang LU, Auteur ; P. LI, Auteur ; J. FANG, Auteur ; Li YI, Auteur Article en page(s) : p.4698-4706 Langues : Anglais (eng) Mots-clés : Autism spectrum disorders  Rule learning  Trust and deception Index. décimale : PER Périodiques Résumé : This study examines how the awareness of social situation affects rule learning in children with autism spectrum disorders (ASD) using computer-based distrust and deception games. Twenty-eight 4- to 7-year-old children with ASD and 28 age- and IQ-matched typically developing (TD) peers learned the distrusting and deceptive rules in a non-social condition, in which they were playing with a computer, or a social condition with another person pretending to interact via a computer. Results showed intact rule-learning ability in the ASDs in the non-social condition, but poorer overall performance and slower learning process than TD children when they thought that they interacted with a human opponent. Rule learning in ASD was affected by their beliefs about the social context.

Trust and Deception in Children with Autism Spectrum Disorders: A Social Learning Perspective / Yiying YANG in Journal of Autism and Developmental Disorders, 47-3 (March 2017)  

Public ISBD [article]  inJournal of Autism and Developmental Disorders > 47-3 (March 2017) . - p.615-625 Titre : Trust and Deception in Children with Autism Spectrum Disorders: A Social Learning Perspective Type de document : texte imprimé Auteurs : Yiying YANG, Auteur ; Yuan TIAN, Auteur ; Jing FANG, Auteur ; Haoyang LU, Auteur ; Kunlin WEI, Auteur ; Li YI, Auteur Article en page(s) : p.615-625 Langues : Anglais (eng) Mots-clés : Autism Spectrum Disorder  Trust  Deception  Social learning Index. décimale : PER Périodiques Résumé : Previous research has demonstrated abnormal trust and deception behaviors in children with Autism Spectrum Disorders (ASD), and we aimed to examine whether these abnormalities were primarily due to their specific deficits in social learning. We tested 42 high-functioning children with ASD and 38 age- and ability-matched typically developing (TD) children in trust and deception tasks and a novel condition with reduced social components. Results indicated that while TD children improved their performance with more social components, children with ASD lacked this additional performance gain, though they performed similarly as TD children in the condition with reduced social components. Our findings highlight that deficits of ASD in trust and deception are primarily associated with failure of use of social cues.
