DIEHL, Auteur ; Molly LOSH, Auteur Article en page(s) : p.3032-3045 Langues : Anglais (eng) Mots-clés : Acoustic  Autism spectrum disorder  Broad autism phenotype  Prosody Index. décimale : PER Périodiques Résumé : This study examined prosody through characterization of acoustic properties of the speech of individuals with ASD and their parents, during narration. A subset of utterances were low-pass filtered and rated for differences in intonation, speech rate, and rhythm. Listener ratings were minimally related to acoustic measures, underscoring the complexity of atypical prosody in ASD. Acoustic analyses revealed greater utterance-final fundamental frequency excursion size and slower speech rate in the ASD group. Slower speech rate was also evident in the ASD parent group, particularly parents with the broad autism phenotype. Overlapping prosodic differences in ASD and ASD Parent groups suggest that prosodic differences may constitute an important phenotype contributing to ASD features and index genetic liability to ASD among first-degree relatives.

A Preliminary Study of Writing Skills in Adolescents with Autism Across Persuasive, Expository, and Narrative Genres / Johanna R. PRICE in Journal of Autism and Developmental Disorders, 50-1 (January 2020)  

Public ISBD [article]  inJournal of Autism and Developmental Disorders > 50-1 (January 2020) . - p.319-332 Titre : A Preliminary Study of Writing Skills in Adolescents with Autism Across Persuasive, Expository, and Narrative Genres Type de document : Texte imprimé et/ou numérique Auteurs : Johanna R. PRICE, Auteur ; Gary E. MARTIN, Auteur ; Kong CHEN, Auteur ; Jennifer R. JONES, Auteur Article en page(s) : p.319-332 Langues : Anglais (eng) Mots-clés : Adolescents  Autism spectrum disorder  Writing samples  Written language Index. décimale : PER Périodiques Résumé : Writing is often difficult for individuals with autism spectrum disorder (ASD), yet relatively little literature exists that profiles specific strengths and needs within this area. This preliminary investigation compares the written language skills of adolescents with ASD without intellectual disability (n = 14) to typically developing (TD) adolescents (n = 12). Writing samples from persuasive, expository, and narrative genres were elicited. Variables of sample length, writing productivity, syntax, lexical diversity, and macrostructure were analyzed. In the persuasive and expository genres, the ASD group scored significantly lower than the TD group on sample length and some aspects of macrostructure. The ASD group scored higher than the TD group on lexical diversity in the persuasive genre. Other comparisons yielded large effect sizes but were not statistically significant.

Understanding Social Communication Differences in Autism Spectrum Disorder and First-Degree Relatives: A Study of Looking and Speaking / Michelle LEE in Journal of Autism and Developmental Disorders, 50-6 (June 2020)

MARTIN, Auteur ; Peter C. GORDON, Auteur ; Molly LOSH, Auteur Article en page(s) : p.2128-2141 Langues : Anglais (eng) Mots-clés : Autism spectrum disorder  Communication  Eye gaze  Language  Narrative  Visual attention Index. décimale : PER Périodiques Résumé : This study examined narrative ability in ASD and parents across two contexts differing in structure and emotional content, and explored gaze patterns that may underlie narrative differences by presenting narrative tasks on an eye tracker. Participants included 37 individuals with ASD and 38 controls, 151 parents of individuals with ASD and 63 parent controls. The ASD and ASD parent groups demonstrated lower narrative quality than controls in the less structured narrative task only. Subtler, context-dependent differences emerged in gaze and showed some associations with narrative quality. Results indicate a narrative ability profile that may reflect genetic liability to ASD, and subtle links between visual attention and complex language skills that may be influenced by ASD genetic risk.
