Examining Phenotypical Heterogeneity and its Underlying Factors in Gesture Skills of Chinese Autistic Children: Clustering Analysis / Xue-Ke SONG ; Wing-Chee SO in Journal of Autism and Developmental Disorders, 54-9 (September 2024)  

Public ISBD [article]  inJournal of Autism and Developmental Disorders > 54-9 (September 2024) . - p.3504-3515 Titre : Examining Phenotypical Heterogeneity and its Underlying Factors in Gesture Skills of Chinese Autistic Children: Clustering Analysis Type de document : Texte imprimé et/ou numérique Auteurs : Xue-Ke SONG, Auteur ; Wing-Chee SO, Auteur Article en page(s) : p.3504-3515 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : Purpose: The heterogeneity of autism is well documented, but few studies have studied the heterogeneity of gesture production ability in autistic children. The present study aimed to identify subgroups of autistic children who displayed heterogeneous gesture production abilities and explore the underlying factors, including autism characteristics, intellectual ability, and language ability, that were associated with the heterogeneity. Methods: A total of 65 Chinese autistic children (mean age = 5;3) participated. Their autism characteristics and intellectual ability were assessed by standardized measurements. Language output and gesture production were captured from a parent-child interaction task. Results: We conducted a hierarchical cluster analysis and identified four distinct clusters. Cluster 1 and Cluster 2 both had low gesture production whereas Cluster 3 and Cluster 4 had high gesture production. Both Clusters 1 and 2 had relatively strong autism characteristics, in comparison to Clusters 3 and 4. Conclusions: Our findings revealed that children with stronger autism characteristics may gesture less often than those with weaker characteristics. However, the relationship between language ability and intellectual ability and gesture production was not clear. These findings shed light on the directions of intervention on gesture production for autistic children, especially those with stronger autism characteristics.

Examining Phenotypical Heterogeneity in Language Abilities in Chinese-Speaking Children with Autism: A Naturalistic Sampling Approach / Xue-Ke SONG in Journal of Autism and Developmental Disorders, 52-5 (May 2022)  

Public ISBD [article]  inJournal of Autism and Developmental Disorders > 52-5 (May 2022) . - p.1908-1919 Titre : Examining Phenotypical Heterogeneity in Language Abilities in Chinese-Speaking Children with Autism: A Naturalistic Sampling Approach Type de document : Texte imprimé et/ou numérique Auteurs : Xue-Ke SONG, Auteur ; Cassandra LEE, Auteur ; Wing-Chee SO, Auteur Article en page(s) : p.1908-1919 Langues : Anglais (eng) Mots-clés : Autism Spectrum Disorder/diagnosis  Autistic Disorder  China  Cognition  Humans  Language  Cluster analysis  Heterogeneity  Naturalistic sampling approach Index. décimale : PER Périodiques Résumé : Phenotypical heterogeneity in language abilities is a hallmark of autism but remains poorly understood. The present study collected naturalistic language samples from parent-child interactions. We quantified verbal abilities (mean length of utterance, tokens, types) of 50 Chinese-speaking children (M=5; 6) and stratified subgroups based on their autism traits, IQ, and language abilities. Using hierarchical cluster analysis, four groups were identified. Group 1, the least affected group, had mild autism, the highest IQ, and the strongest verbal abilities. Group 2, the severely affected group, had the lowest IQ, most severe autism symptoms, and weakest verbal abilities. Group 3 and Group 4 displayed average levels of verbal abilities and IQ. These findings may characterize the heterogeneous profiles of verbal abilities in Chinese-speaking children.

Whose Gestures are More Predictive of Expressive Language Abilities among Chinese-Speaking Children with Autism? A Comparison of Caregivers' and Children?s Gestures / Wing-Chee SO in Journal of Autism and Developmental Disorders, 53-9 (September 2023)  

Public ISBD [article]  inJournal of Autism and Developmental Disorders > 53-9 (September 2023) . - p.3449-3459 Titre : Whose Gestures are More Predictive of Expressive Language Abilities among Chinese-Speaking Children with Autism?

Previous findings are also inconclusive. In the present study, we coded the gestures produced by the parents and their autistic children in parent-child interactions and compared the influence of their gestures on the children?s expressive language abilities (N=35; M=4;10). Autistic children?s deictic gestures positively predicted their Mean Length Utterance (MLU), word types, and word tokens whereas parents' deictic gesture inputs negatively predicted MLU and word types. The findings shed light on the importance of the gestures made by autistic children, which may trigger parents' gesture-to-word translation.
