Acquisition of Speech Prosody in a Non-native Tone Language by Children With and Without Autism Spectrum Disorder / Si CHEN in Journal of Autism and Developmental Disorders, 56-6 (June 2026)  

Public ISBD [article]  inJournal of Autism and Developmental Disorders > 56-6 (June 2026) . - p.2258-2272 Titre : Acquisition of Speech Prosody in a Non-native Tone Language by Children With and Without Autism Spectrum Disorder Type de document : texte imprimé Auteurs : Si CHEN, Auteur ; Yixin ZHANG, Auteur ; Meixuan LI, Auteur ; Bin LI, Auteur ; Shuang LU, Auteur ; Angel CHAN, Auteur ; Haoyan GE, Auteur ; Tempo TANG, Auteur ; Zhuoming CHEN, Auteur Article en page(s) : p.2258-2272 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : Purpose: Children with autism spectrum disorder (ASD) often show abnormal speech prosody. Tonal languages can pose more difficulties as speakers need to use acoustic cues to make lexical contrasts while encoding the focal function, but the acquisition of speech prosody of non-native languages, especially tonal languages has rarely been investigated. Methods: This study aims to fill in the aforementioned gap by studying prosodic focus-marking in Mandarin by native Cantonese-speaking children with ASD (n = 25), in comparison with their typically developing (TD) peers (n = 20) and native Mandarin-speaking children (n = 20). Natural prosodic marking of different types of focus was elicited by picture-based prompt questions, recorded and analyzed acoustically. Results: The autistic children made use of fewer acoustic cues and produced less evident on-focus expansion in these cues than TD, especially the native-Mandarin speaking peers. They also demonstrated a clear preference to on-focus expansion than to post-focus compression. These children, together with their native Cantonese-speaking peers, also hyper-performed in tone realization, prioritizing lexical prosody over focus marking. Such hyper-performance may further limit their use of prosodic cues in focus marking. However, the difficulties the autistic children faced in the acquisition of speech prosody in a non-native tone language, though found, are not more than those they face in their mother tongue. Conclusion: Multilingual exposure may help the autistic children master the use of some focus marking strategies though they still need interventions to help them to implement their focus-marking knowledge more sufficiently in both native and non-native languages.

Systematic review and meta-analysis: multimodal functional and anatomical neural alterations in autism spectrum disorder / Zixuan GUO in Molecular Autism, 15 (2024)  

Public ISBD [article]  inMolecular Autism > 15 (2024) . - 16p. Titre : Systematic review and meta-analysis: multimodal functional and anatomical neural alterations in autism spectrum disorder Type de document : texte imprimé Auteurs : Zixuan GUO, Auteur ; Xinyue TANG, Auteur ; Shu XIAO, Auteur ; Hong YAN, Auteur ; Shilin SUN, Auteur ; Zibin YANG, Auteur ; Li HUANG, Auteur ; Zhuoming CHEN, Auteur ; Ying WANG, Auteur Article en page(s) : 16p. Langues : Anglais (eng) Mots-clés : Humans  Autism Spectrum Disorder/diagnostic imaging  Brain/diagnostic imaging  Cerebral Cortex/diagnostic imaging  Gray Matter/diagnostic imaging  Gyrus Cinguli  Magnetic Resonance Imaging/methods  Autism spectrum disorder  Gray matter volume  Meta-analysis  Resting-state functional imaging  Voxel-based morphometry Index. décimale : PER Périodiques Résumé : BACKGROUND: This meta-analysis aimed to explore the most robust findings across numerous existing resting-state functional imaging and voxel-based morphometry (VBM) studies on the functional and structural brain alterations in individuals with autism spectrum disorder (ASD). METHODS: A whole-brain voxel-wise meta-analysis was conducted to compare the differences in the intrinsic functional activity and gray matter volume (GMV) between individuals with ASD and typically developing individuals (TDs) using Seed-based d Mapping software. RESULTS: A total of 23 functional imaging studies (786 ASD, 710 TDs) and 52 VBM studies (1728 ASD, 1747 TDs) were included. Compared with TDs, individuals with ASD displayed resting-state functional decreases in the left insula (extending to left superior temporal gyrus [STG]), bilateral anterior cingulate cortex/medial prefrontal cortex (ACC/mPFC), left angular gyrus and right inferior temporal gyrus, as well as increases in the right supplementary motor area and precuneus. For VBM meta-analysis, individuals with ASD displayed decreased GMV in the ACC/mPFC and left cerebellum, and increased GMV in the left middle temporal gyrus (extending to the left insula and STG), bilateral olfactory cortex, and right precentral gyrus. Further, individuals with ASD displayed decreased resting-state functional activity and increased GMV in the left insula after overlapping the functional and structural differences. CONCLUSIONS: The present multimodal meta-analysis demonstrated that ASD exhibited similar alterations in both function and structure of the insula and ACC/mPFC, and functional or structural alterations in the default mode network (DMN), primary motor and sensory regions. These findings contribute to further understanding of the pathophysiology of ASD.
