Brief Report: Autistic Traits Predict Spectral Correlates of Vowel Intelligibility for Female Speakers / Jason BISHOP in Journal of Autism and Developmental Disorders, 52-5 (May 2022)

Titre : Brief Report: Autistic Traits Predict Spectral Correlates of Vowel Intelligibility for Female Speakers Type de document : Texte imprimé et/ou numérique Auteurs : Jason BISHOP, Auteur ; Chen ZHOU, Auteur ; Katarina ANTOLOVIC, Auteur ; Lauren GREBE, Auteur ; Kyung Hae HWANG, Auteur ; Gerald IMAEZUE, Auteur ; Ekaterina KISTANOVA, Auteur ; Kyung Eun LEE, Auteur ; Katherine PAULINO, Auteur ; Sichen ZHANG, Auteur Article en page(s) : p.2344-2349 Langues : Anglais (eng) Mots-clés : Autism Spectrum Disorder Autistic Disorder Female Humans Phonetics Speech Acoustics Speech Intelligibility Speech Perception Speech Production Measurement Autism-spectrum quotient Broad autism phenotype Intelligibility Pragmatic communication Sex differences Speech production Index. décimale : PER Périodiques Résumé : A growing body of research finds that neurotypical autistic traits are predictive of speech perception and language comprehension patterns, but considerably less is known about the influence of these traits on speech production. In this brief report, we present an analysis of vowel productions from 74 American English speakers who participated in a communicative speaking task. Results show higher autistic trait load to be broadly and inversely related to spectral correlates of vowel intelligibility. However, the statistical significance of this relationship is specific to autistic traits along the pragmatic communication dimension, and limited to female speakers.

Titre : Linguistic camouflage in girls with autism spectrum disorder Type de document : Texte imprimé et/ou numérique Auteurs : Julia PARISH-MORRIS, Auteur ; M. Y. LIBERMAN, Auteur ; C.

Langues : Anglais (eng) Mots-clés : Autism Disfluency Filled pauses Gender differences Language Linguistic camouflage Pragmatic communication Sex differences Index. décimale : PER Périodiques Résumé : BACKGROUND: Autism spectrum disorder (ASD) is diagnosed more frequently in boys than girls, even when girls are equally symptomatic. Cutting-edge behavioral imaging has detected "camouflaging" in girls with ASD, wherein social behaviors appear superficially typical, complicating diagnosis. The present study explores a new kind of camouflage based on language differences. Pauses during conversation can be filled with words like UM or UH, but research suggests that these two words are pragmatically distinct (e.g., UM is used to signal longer pauses, and may correlate with greater social communicative sophistication than UH). Large-scale research suggests that women and younger people produce higher rates of UM during conversational pauses than do men and older people, who produce relatively more UH. Although it has been argued that children and adolescents with ASD use UM less often than typical peers, prior research has not included sufficient numbers of girls to examine whether sex explains this effect. Here, we explore UM vs. UH in school-aged boys and girls with ASD, and ask whether filled pauses relate to dimensional measures of autism symptom severity. METHODS: Sixty-five verbal school-aged participants with ASD (49 boys, 16 girls, IQ estimates in the average range) participated, along with a small comparison group of typically developing children (8 boys, 9 girls). Speech samples from the Autism Diagnostic Observation Schedule were orthographically transcribed and time-aligned, with filled pauses marked. Parents completed the Social Communication Questionnaire and the Vineland Adaptive Behavior Scales. RESULTS: Girls used UH less often than boys across both diagnostic groups. UH suppression resulted in higher UM ratios for girls than boys, and overall filled pause rates were higher for typical children than for children with ASD. Higher UM ratios correlated with better socialization in boys with ASD, but this effect was driven by increased use of UH by boys with greater symptoms. CONCLUSIONS: Pragmatic language markers distinguish girls and boys with ASD, mirroring sex differences in the general population. One implication of this finding is that typical-sounding disfluency patterns (i.e., reduced relative UH production leading to higher UM ratios) may normalize the way girls with ASD sound relative to other children, serving as "linguistic camouflage" for a naive listener and distinguishing them from boys with ASD. This first-of-its-kind study highlights the importance of continued commitment to understanding how sex and gender change the way that ASD manifests, and illustrates the potential of natural language to contribute to objective "behavioral imaging" diagnostics for ASD.
