Do Individuals with High-Functioning Autism Who Speak a Tone Language Show Intonation Deficits? / Kary K. L. CHAN in Journal of Autism and Developmental Disorders, 46-5 (May 2016)
[article]
Titre : Do Individuals with High-Functioning Autism Who Speak a Tone Language Show Intonation Deficits? Type de document : Texte imprimé et/ou numérique Auteurs : Kary K. L. CHAN, Auteur ; Carol K. S. TO, Auteur Article en page(s) : p.1784-1792 Langues : Anglais (eng) Mots-clés : Prosody Intonation Autism spectrum disorders High-functioning autism Tone language Cantonese Index. décimale : PER Périodiques Résumé : This study investigated whether intonation deficits were observed in 19 Cantonese-speaking adults with high-functioning autism (HFA) when compared to 19 matched neurotypical (NT) controls. This study also investigated the use of sentence-final particles (SFPs) and their relationship with intonation in both groups. Standard deviations (SDs) of the fundamental frequency (F0), the total number and the type of SFPs were calculated based on narrative samples. The HFA group demonstrated significantly higher SD of F0 and a positive correlation between the type of SFPs and SD of F0. Both groups produced a similar total number and type of SFPs. The results supported the universality of atypical intonation in ASD. The relationship between intonation and SFPs could be further explored by focusing on sentences containing SFPs.

Titre : Perception and Production of Statement-Question Intonation in Autism Spectrum Disorder: A Developmental Investigation Type de document : Texte imprimé et/ou numérique Auteurs : Li WANG, Auteur ; C. Philip BEAMAN, Auteur ; Cunmei JIANG, Auteur ; Fang LIU, Auteur Article en page(s) : p.3456-3472 Langues : Anglais (eng) Mots-clés : Adolescent Adult Autism Spectrum Disorder/diagnosis Child Humans Music Pitch Discrimination Pitch Perception Speech Speech Perception Autism spectrum disorder Intonation Pitch Index. décimale : PER Périodiques Résumé : Prosody or "melody in speech" in autism spectrum disorder (ASD) is often perceived as atypical. This study examined perception and production of statements and questions in 84 children, adolescents and adults with and without ASD, as well as participants' pitch direction discrimination thresholds. The results suggested that the abilities to discriminate (in both speech and music conditions), identify, and imitate statement-question intonation were intact in individuals with ASD across age cohorts. Sensitivity to pitch direction predicted performance on intonation processing in both groups, who also exhibited similar developmental changes. These findings provide evidence for shared mechanisms in pitch processing between speech and music, as well as associations between low- and high-level pitch processing and between perception and production of pitch.

Titre : Perception of Melodic Contour and Intonation in Autism Spectrum Disorder: Evidence From Mandarin Speakers Type de document : Texte imprimé et/ou numérique Auteurs : Jun JIANG, Auteur ; Fang LIU, Auteur ; Xuan WAN, Auteur ; Cunmei JIANG, Auteur Année de publication : 2015 Article en page(s) : p.2067-2075 Langues : Anglais (eng) Mots-clés : Autism spectrum disorder Melodic contour Intonation Discrimination Identification Index. décimale : PER Périodiques Résumé : Tone language experience benefits pitch processing in music and speech for typically developing individuals. No known studies have examined pitch processing in individuals with autism who speak a tone language. This study investigated discrimination and identification of melodic contour and speech intonation in a group of Mandarin-speaking individuals with high-functioning autism. Individuals with autism showed superior melodic contour identification but comparable contour discrimination relative to controls. In contrast, these individuals performed worse than controls on both discrimination and identification of speech intonation. These findings provide the first evidence for differential pitch processing in music and speech in tone language speakers with autism, suggesting that tone language experience may not compensate for speech intonation perception deficits in individuals with autism.

Titre : Atypical Prosody in Asperger Syndrome: Perceptual and Acoustic Measurements Type de document : Texte imprimé et/ou numérique Auteurs : Marisa G. FILIPE, Auteur ; Sónia FROTA, Auteur ; São Luís CASTRO, Auteur ; Selene G. VICENTE, Auteur Article en page(s) : p.1972-1981 Langues : Anglais (eng) Mots-clés : Asperger syndrome Atypical prosody Autism spectrum disorders Intonation Index. décimale : PER Périodiques Résumé : It is known that individuals with Asperger syndrome (AS) may show no problems with regard to what is said (e.g., lexical content) but tend to have difficulties in how utterances are produced, i.e., they may show prosodic impairments. In the present study, we focus on the use of prosodic features to express grammatical meaning. Specifically, we explored the sentence type difference between statements and questions that is conveyed by intonation, using perceptual and acoustic measurements. Children aged 8 and 9 years with AS (n = 12) were matched according to age and nonverbal intelligence with typically developing peers (n = 17). Although children with AS could produce categorically accurate prosodic patterns, their prosodic contours were perceived as odd by adult listeners, and acoustic measurements showed alterations in duration and pitch. Additionally, children with AS had greater variability in fundamental frequency contours compared to typically developing peers.

[article]
Titre : Behavioral predictors of improved speech output in minimally verbal children with autism Type de document : Texte imprimé et/ou numérique Auteurs : Karen CHENAUSKY, Auteur ; A. NORTON, Auteur ; Helen TAGER-FLUSBERG, Auteur ; G. SCHLAUG, Auteur Article en page(s) : p.1356-1365 Langues : Anglais (eng) Mots-clés : autism spectrum disorder intonation longitudinal data analysis minimally verbal spoken language Index. décimale : PER Périodiques Résumé : We investigated the relationship between eight theoretically motivated behavioral variables and a spoken-language-related outcome measure, after 25 sessions of treatment for speech production in 38 minimally verbal children with autism. After removing potential predictors that were uncorrelated with the outcome variable, two remained. We used both complete-case and multiple-imputation analyses to address missing predictor data and performed linear regressions to identify significant predictors of change in percent syllables approximately correct after treatment. Baseline phonetic inventory (the number of English phonemes repeated correctly) was the most robust predictor of improvement. In the group of 17 participants with complete data, ADOS score also significantly predicted the outcome. In contrast to some earlier studies, nonverbal IQ, baseline levels of expressive language, and younger age did not significantly predict improvement. The present results are not only consistent with previous studies showing that verbal imitation and autism severity significantly predict spoken language outcomes in preschool-aged minimally verbal children with autism, but also extend these findings to older minimally verbal children with autism. Autism Res 2018, 11: 1356-1365. (c) 2018 International Society for Autism Research, Wiley Periodicals, Inc. LAY SUMMARY: We wished to understand what baseline factors predicted whether minimally verbal children with autism would improve after treatment for spoken language. The outcome measure was change in percentage (%) syllables approximately correct on a set of 30 two-syllable words or phrases. Fifteen were both practiced in treatment and tested; the remainder were not practiced in treatment, but only tested, to assess how well children were able to generalize their new skills to an untrained set of words. Potential predictors tested were sex, age, expressive language, phonetic inventory (the number of English speech sounds repeated correctly), autism severity, and nonverbal IQ. Phonetic inventory and (for some children) autism severity predicted children's posttreatment improvement. Nonverbal IQ and expressive language ability did not predict improvement, nor did younger age, suggesting that some older children with autism may be candidates for speech therapy.
