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

Titre : The Perceived Social Context Modulates Rule Learning in Autism Type de document : Texte imprimé et/ou numérique Auteurs : H. LU, Auteur ; P. LI, Auteur ; J. FANG, Auteur ; L. 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.
