Two experiments were designed to test how acoustic, phonetic and semantic properties of the stimuli contributed to the neural responses for pitch change detection and involuntary attentional orienting. In comparison with age-matched (6–12 years) typically developing controls (16 participants in Experiment 1, 18 in Experiment 2), children with autism (18 participants in Experiment 1, 16 in Experiment 2) showed enhanced neural discriminatory sensitivity in the nonspeech conditions but not for speech stimuli. The results indicate domain specificity of enhanced pitch processing in autism, which may interfere with lexical tone acquisition and language development for children who speak a tonal language.

Recognition of affective prosody in autism spectrum conditions: A systematic review and meta-analysis / Minyue ZHANG in Autism, 26-4 (May 2022)  

Public ISBD [article]  inAutism > 26-4 (May 2022) . - p.798-813 Titre : Recognition of affective prosody in autism spectrum conditions: A systematic review and meta-analysis Type de document : Texte imprimé et/ou numérique Auteurs : Minyue ZHANG, Auteur ; Suyun XU, Auteur ; Yu CHEN, Auteur ; Yi LIN, Auteur ; Hongwei DING, Auteur ; Yang ZHANG, Auteur Article en page(s) : p.798-813 Langues : Anglais (eng) Mots-clés : Autism Spectrum Disorder/psychology  Autistic Disorder  Emotions  Humans  Recognition, Psychology  Speech  Speech Perception  affective prosody  autism spectrum conditions  emotion recognition  meta-analysis Index. décimale : PER Périodiques Résumé : Differences in understanding others' emotions and attitudes through features in speech (e.g. intonation) have been observed in individuals with autism spectrum conditions, which contribute greatly to their social communication challenges. However, some studies reported that individuals with autism spectrum condition performed comparably to typically developing individuals on affective prosody recognition. Here, we provide a comprehensive review with statistical analysis of 23 existing studies on this topic to examine potential factors that could explain the discrepancies. Compared with typically developing individuals, autism spectrum condition participants generally appeared to encounter more difficulties in affective prosody recognition. But this finding was likely due to the tendency of the existing research to overly focus on deficits in autism. The affective prosody recognition performance in individuals with autism spectrum condition was closely related to the number of answer options offered to them. Moreover, the degree of difficulty in affective prosody recognition encountered by individuals with autism spectrum condition varied across emotions. The findings of this systematic review highlighted the need for further research on affective prosody recognition in autism (e.g. studies that include tonal language speakers and autism spectrum condition individuals with lower cognitive or verbal abilities).

Reduced Neural Specialization for Word-level Linguistic Prosody in Children with Autism / Luodi YU in Journal of Autism and Developmental Disorders, 53-11 (November 2023)  

Public ISBD [article]  inJournal of Autism and Developmental Disorders > 53-11 (November 2023) . - p.4351-4367 Titre : Reduced Neural Specialization for Word-level Linguistic Prosody in Children with Autism Type de document : Texte imprimé et/ou numérique Auteurs : Luodi YU, Auteur ; Dan HUANG, Auteur ; Suiping WANG, Auteur ; Yang ZHANG, Auteur Article en page(s) : p.4351-4367 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : Children with autism often show atypical brain lateralization for speech and language processing, however, it is unclear what linguistic component contributes to this phenomenon. Here we measured event-related potential (ERP) responses in 21 school-age autistic children and 25 age-matched neurotypical (NT) peers during listening to word-level prosodic stimuli. We found that both groups displayed larger late negative response (LNR) amplitude to native prosody than to nonnative prosody; however, unlike the NT group exhibiting left-lateralized LNR distinction of prosodic phonology, the autism group showed no evidence of LNR lateralization. Moreover, in both groups, the LNR effects were only present for prosodic phonology but not for phoneme-free prosodic acoustics. These results extended the findings of inadequate neural specialization for language in autism to sub-lexical prosodic structures.

Universality of categorical perception deficit in developmental dyslexia: an investigation of Mandarin Chinese tones / Yajing ZHANG in Journal of Child Psychology and Psychiatry, 53-8 (August 2012)  

Public ISBD [article]  inJournal of Child Psychology and Psychiatry > 53-8 (August 2012) . - p.874-882 Titre : Universality of categorical perception deficit in developmental dyslexia: an investigation of Mandarin Chinese tones Type de document : Texte imprimé et/ou numérique Auteurs : Yajing ZHANG, Auteur ; Linjun ZHANG, Auteur ; Hua SHU, Auteur ; Jie XI, Auteur ; Han WU, Auteur ; Yang ZHANG, Auteur ; Ping LI, Auteur Année de publication : 2012 Article en page(s) : p.874-882 Langues : Anglais (eng) Mots-clés : Dyslexia  categorical perception  lexical tones  event-related potential  mismatch negativity Index. décimale : PER Périodiques Résumé : Background:  While previous studies have shown that children affected by dyslexia exhibit a deficit in categorical perception of segmental features in alphabetic languages, it remains unclear whether the categorical perception deficit generalizes to nonalphabetic languages at the suprasegmental level. In this study, we investigated the occurrence of categorical perception deficit in Mandarin lexical tones in Chinese children with dyslexia. Methods:  Both behavioral and electrophysiological measures were taken to compare Chinese dyslexic children with age-matched controls. Auditory event-related potentials were collected with a passive listening oddball paradigm. Results:  Behavioral data showed that dyslexic children perceived lexical tone contrasts less categorically and less precisely than age-matched controls. Consistent with the behavioral data, the across-category tone contrast elicited larger mismatch negativity than the within-category distinction in the left hemisphere for the age-matched controls but not for the dyslexic children. Conclusion:  The behavioral and electrophysiological results demonstrate impaired categorical perception of lexical tones in Chinese children with dyslexia. Our findings support the hypothesis that children affected by dyslexia have a general deficit in categorical perception of speech, which generalizes to nonalphabetic languages at the suprasegmental level.
