Categorical perception of Mandarin lexical tones in language-delayed autistic children / Yicheng RONG in Autism, 27-5 (July 2023)  

Public ISBD [article]  inAutism > 27-5 (July 2023) . - p.1426-1437 Titre : Categorical perception of Mandarin lexical tones in language-delayed autistic children Type de document : texte imprimé Auteurs : Yicheng RONG, Auteur ; Yi WENG, Auteur ; Fei CHEN, Auteur ; Gang PENG, Auteur Article en page(s) : p.1426-1437 Langues : Anglais (eng) Mots-clés : autistic children;categorical perception;language ability;lexical tones;Mandarin;tone language Index. décimale : PER Périodiques Résumé : Enhanced pitch perception has been identified in autistic individuals, but it remains understudied whether such enhancement can be observed in the lexical tone perception of language-delayed autistic children. This study examined the categorical perception of Mandarin lexical tones in 23 language-delayed autistic children and two groups of non-autistic children, with one matched on chronological age (n 23) and the other on developmental age in language ability (n 23). The participants were required to identify and discriminate lexical tones. A wider identification boundary width and a lower between-category discrimination accuracy were found in autistic children than their chronological-age-matched non-autistic peers, but the autistic group exhibited seemingly comparable performance to the group of developmental-age-matched non-autistic children. While both non-autistic groups displayed a typical categorical perception pattern with enhanced sensitivity to between-category tone pairs relative to within-category ones, such a categorical perception pattern was not observed in the autistic group. These findings suggest among language-delayed autistic children with a developmental age around 4, categorical perception is still developing. Finally, we found categorical perception performance correlated with language ability, indicating autistic children s language disability might be predictive of their poor categorical perception of speech sounds. Lay abstract Some theories suggested that autistic people have better pitch perception skills than non-autistic people. However, in a context where pitch patterns are used to differentiate word meanings (i.e. lexical tones), autistic people may encounter difficulties, especially those with less language experience. We tested this by asking language-delayed autistic children to identify and discriminate two Mandarin lexical tones (/yi/ with Tone 1, meaning "clothes"; /yi/ with Tone 2, meaning "aunt"; /yi/: the standard romanization of Mandarin Chinese). On average, these autistic children were 7.35 years old, but their developmental age in language ability was 4.20, lagging behind 7-year-old non-autistic children in terms of language ability. Autistic children s performance in identifying and discriminating lexical tones was compared with two groups of non-autistic children: one group was matched with the autistic group on age, and the other was matched based on language ability. Autistic children performed differently from the non-autistic children matched on age, while autistic and non-autistic children matched on language ability exhibited seemingly similar performance. However, both the non-autistic groups have developed the perceptual ability to process lexical tones as different categories, but this ability was still developing in autistic children. Finally, we found autistic children who performed worse in identifying lexical tones had poorer language ability. The results suggest that language disability might have adverse influence on the development of skills of speech sound processing.

Emotional Prosody Recognition in Autism Spectrum Disorder Without Intellectual Disability: A Systematic Review and Meta-Analysis / Qiyun LUO in Journal of Autism and Developmental Disorders, 56-9 (September 2026)  

Public ISBD [article]  inJournal of Autism and Developmental Disorders > 56-9 (September 2026) . - p.3489-3502 Titre : Emotional Prosody Recognition in Autism Spectrum Disorder Without Intellectual Disability: A Systematic Review and Meta-Analysis Type de document : texte imprimé Auteurs : Qiyun LUO, Auteur ; Xiaoyan ZENG, Auteur ; Fei CHEN, Auteur ; Chen KUANG, Auteur Article en page(s) : p.3489-3502 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : Emotional prosody recognition is vital for social interaction and has become a key focus in autism research. However, findings regarding emotional prosody recognition in individuals with autism spectrum disorder without intellectual disability (ASD-without-ID) remain inconsistent. This study aims to address this inconsistency through a systematic review and meta-analysis, exploring potential factors that may account for the inconsistent results. A search across four major electronic databases identified 29 eligible studies comparing emotional prosody recognition in ASD-without-ID and typically developing (TD) participants. We identified several participant- and methodology-related moderators across these studies. Using a random-effects model, we found a moderate-to-large pooled effect (Hedges’ g = − 0.65) for emotional prosody recognition in ASD-without-ID participants, which remained stable after adjusting for publication bias through the trim-and-fill method. Emotional complexity and participant age significantly moderated the heterogeneity of effect sizes across studies. The results indicate moderate differences in the recognition of basic emotions through prosody between individuals with ASD-without-ID and TD individuals, with more pronounced differences for complex emotions. The findings emphasize the distinct developmental trajectories of ASD-without-ID individuals. We highlight the need for further investigation into the underlying factors and mechanisms affecting emotional prosody recognition in this population, including meta-analyses examining the moderate effects of various IQ measures and studies involving speakers of tonal languages.

Linguistic Tone and Non-Linguistic Pitch Imitation in Children with Autism Spectrum Disorders: A Cross-Linguistic Investigation / Fei CHEN in Journal of Autism and Developmental Disorders, 52-5 (May 2022)

This cross-linguistic study evaluated the performance of imitating Cantonese lexical tones and their non-linguistic (nonspeech) counterparts by Cantonese- and Mandarin-speaking children with and without ASD. Acoustic analyses showed that, compared with typically developing peers, children with ASD exhibited increased pitch variations when imitating lexical tones, while performed similarly when imitating the nonspeech counterparts. Furthermore, Mandarin-speaking children with ASD failed to exploit the phonological knowledge of segments to improve the imitation accuracy of non-native lexical tones. These findings help clarify the speech-specific pitch processing atypicality and phonological processing deficit in tone-language-speaking children with ASD.
