Pitch Processing in Tonal-Language-Speaking Children with Autism: An Event-Related Potential Study / Luodi YU in Journal of Autism and Developmental Disorders, 45-11 (November 2015)
[article]
Titre : Pitch Processing in Tonal-Language-Speaking Children with Autism: An Event-Related Potential Study Type de document : Texte imprimé et/ou numérique Auteurs : Luodi YU, Auteur ; Yuebo FAN, Auteur ; Zhizhou DENG, Auteur ; Dan HUANG, Auteur ; Suiping WANG, Auteur ; Yang ZHANG, Auteur Article en page(s) : p.3656-3667 Langues : Anglais (eng) Mots-clés : Autism Pitch processing Speech perception Language development Event-related potentials (ERPs) Mismatch negativity (MMN) Index. décimale : PER Périodiques Résumé : The present study investigated pitch processing in Mandarin-speaking children with autism using event-related potential measures. 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.

Titre : Public knowledge and stigma of autism spectrum disorder: Comparing China with the United States Type de document : Texte imprimé et/ou numérique Auteurs : Luodi YU, Auteur ; Sheri T. STRONACH, Auteur ; Ashley J. HARRISON, Auteur Article en page(s) : p.1531-1545 Langues : Anglais (eng) Mots-clés : autism knowledge autism spectrum disorder awareness cross-cultural comparison stigma Index. décimale : PER Périodiques Résumé : Autism spectrum disorder in China differs considerably from autism spectrum disorder in the West in terms of prevalence estimates, education opportunities, and life outcomes of autistic people. The lack of autism spectrum disorder awareness could be a key factor underlying the disparities. To date, there has been no evaluation of autism spectrum disorder knowledge among the general public of China. Using the Autism Stigma and Knowledge Questionnaire developed for use in diverse cultural contexts, this study uncovered profoundly different public views about autism spectrum disorder in China compared with the United States. Determined by cognitive diagnosis modeling, 86%-91% of the surveyed U.S. citizens (N?=?1127) achieved adequate autism spectrum disorder knowledge in diagnosis/symptoms, etiology, and treatment, whereas for the Chinese citizens (N?=?1254) the percentages were only 57%-65%. Moreover, 14% of the participants from the United States were classified to endorse autism spectrum disorder stigma; in comparison, 38% of the Chinese participants endorsed autism spectrum disorder stigma. The Chinese citizens displayed knowledge deficits primarily in the areas of autism spectrum disorder core symptoms, comorbid intellectual impairment, and prognosis. Sociodemographic factors associated with the Chinese citizen's misconceptions included gender, ethnicity, social economic factors, among others. These results have important implications for increasing public awareness and promoting community participation for autistic individuals in China.Lay abstractASD in China differs considerably from ASD in the West in terms of prevalence estimates, education opportunities and life outcomes of autistic people. The lack of ASD awareness could be a key factor underlying these disparities. We asked 1127 U.S. citizens and 1254 Chinese citizens about their autism knowledge using the Autism Stigma and Knowledge Questionnaire (ASK-Q).The results indicated profoundly different public views about ASD in China compared to the U.S. Specifically, only 57%-65% of the Chinese citizens demonstrated adequate ASD knowledge compared to 86%-91% in the U.S. citizens. Fourteen percent of the U.S. citizens were shown to hold stigma beliefs towards ASD; in comparison, 38% of the Chinese citizens indicated ASD stigma. The Chinese citizens displayed misconceptions about ASD related to symptoms, causes, and possible long-term outcomes. In China but not in the U.S., male citizens and citizens with lower social economic status were more likely to have misconceptions about ASD than others were. The findings of this research can help increase public awareness about ASD and create a more inclusive environment for autistic people in China.

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.
