Categorical perception of Mandarin lexical tones in language-delayed autistic children / Yicheng RONG in Autism, 27-5 (July 2023)
[article]
Titre : Categorical perception of Mandarin lexical tones in language-delayed autistic children Type de document : Texte imprimé et/ou numérique 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.

Titre : Linguistic Tone and Non-Linguistic Pitch Imitation in Children with Autism Spectrum Disorders: A Cross-Linguistic Investigation Type de document : Texte imprimé et/ou numérique Auteurs : Fei CHEN, Auteur ; Candice Chi-Hang CHEUNG, Auteur ; Gang PENG, Auteur Article en page(s) : p.2325-2343 Langues : Anglais (eng) Mots-clés : Autism Spectrum Disorder Child Humans Imitative Behavior Linguistics Pitch Perception Speech Perception Asd Cantonese Imitation Lexical tone Mandarin Non-linguistic pitch Index. décimale : PER Périodiques Résumé : The conclusions on prosodic pitch features in autism spectrum disorders (ASD) have primarily been derived from studies in non-tonal language speakers. 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.
