Face-viewing patterns predict audiovisual speech integration in autistic children / Shuyuan FENG in Autism Research, 14-12 (December 2021)

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.

Reward learning modulates the attentional processing of faces in children with and without autism spectrum disorder / Tianbi LI in Autism Research, 10-11 (November 2017)  

Public ISBD [article]  inAutism Research > 10-11 (November 2017) . - p.1797-1807 Titre : Reward learning modulates the attentional processing of faces in children with and without autism spectrum disorder Type de document : texte imprimé Auteurs : Tianbi LI, Auteur ; Xueqin WANG, Auteur ; Junhao PAN, Auteur ; Shuyuan FENG, Auteur ; Mengyuan GONG, Auteur ; Yaxue WU, Auteur ; Guoxiang LI, Auteur ; Sheng LI, Auteur ; Li YI, Auteur Article en page(s) : p.1797-1807 Langues : Anglais (eng) Mots-clés : autism spectrum disorder  reward learning  face recognition  attention  visual search  face processing Index. décimale : PER Périodiques Résumé : The processing of social stimuli, such as human faces, is impaired in individuals with autism spectrum disorder (ASD), which could be accounted for by their lack of social motivation. The current study examined how the attentional processing of faces in children with ASD could be modulated by the learning of face-reward associations. Sixteen high-functioning children with ASD and 20 age- and ability-matched typically developing peers participated in the experiments. All children started with a reward learning task, in which the children were presented with three female faces that were attributed with positive, negative, and neutral values, and were required to remember the faces and their associated values. After this, they were tested on the recognition of the learned faces and a visual search task in which the learned faces served as the distractor. We found a modulatory effect of the face-reward associations on the visual search but not the recognition performance in both groups despite the lower efficacy among children with ASD in learning the face-reward associations. Specifically, both groups responded faster when one of the distractor faces was associated with positive or negative values than when the distractor face was neutral, suggesting an efficient attentional processing of these reward-associated faces. Our findings provide direct evidence for the perceptual-level modulatory effect of reward learning on the attentional processing of faces in individuals with ASD. Autism Res 2017, 10: 1797–1807. © 2017 International Society for Autism Research, Wiley Periodicals, Inc. Lay Summary In our study, we tested whether the face processing of individuals with ASD could be changed when the faces were associated with different social meanings. We found no effect of social meanings on face recognition, but both groups responded faster in the visual search task when one of the distractor faces was associated with positive or negative values than when the neutral face. The findings suggest that children with ASD could efficiently process faces associated with different values like typical children.
