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.

Association between anger rumination and autism symptom severity, depression symptoms, aggression, and general dysregulation in adolescents with autism spectrum disorder / Shivani P. PATEL in Autism, 21-2 (February 2017)  

Public ISBD [article]  inAutism > 21-2 (February 2017) . - p.181-189 Titre : Association between anger rumination and autism symptom severity, depression symptoms, aggression, and general dysregulation in adolescents with autism spectrum disorder Type de document : Texte imprimé et/ou numérique Auteurs : Shivani P. PATEL, Auteur ; Taylor N. DAY, Auteur ; Neil JONES, Auteur ; Carla A. MAZEFSKY, Auteur Article en page(s) : p.181-189 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : Rumination has a large direct effect on psychopathology but has received relatively little attention in autism spectrum disorder despite the propensity to perseverate in this population. This study provided initial evidence that adolescents with autism spectrum disorder self-report more anger-focused rumination than typically developing controls, though there was substantial within-group variability. Anger rumination was positively correlated with autism symptom severity with both groups combined. Future studies that include measures of perseveration on special interests are needed to understand whether anger rumination is a manifestation of a perseverative type of repetitive behavior or a distinct trait. Even when controlling for autism symptom severity, however, anger-focused rumination was associated with poorer functioning, including more depression symptoms and overall emotional and behavioral dysregulation. Therefore, further inquiry regarding anger rumination in autism spectrum disorder is clinically important, and the potential impact of rumination-focused interventions should be explored.

Neural Processing of Speech Sounds in ASD and First-Degree Relatives / Shivani P. PATEL in Journal of Autism and Developmental Disorders, 53-8 (August 2023)  

Public ISBD [article]  inJournal of Autism and Developmental Disorders > 53-8 (August 2023) . - p.3257-3271 Titre : Neural Processing of Speech Sounds in ASD and First-Degree Relatives Type de document : Texte imprimé et/ou numérique Auteurs : Shivani P. PATEL, Auteur ; Molly WINSTON, Auteur ; Janna GUILFOYLE, Auteur ; Trent NICOL, Auteur ; Gary E. MARTIN, Auteur ; Kritika NAYAR, Auteur ; Nina KRAUS, Auteur ; Molly LOSH, Auteur Article en page(s) : p.3257-3271 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : Efficient neural encoding of sound plays a critical role in speech and language, and when impaired, may have reverberating effects on communication skills. This study investigated disruptions to neural processing of temporal and spectral properties of speech in individuals with ASD and their parents and found evidence of inefficient temporal encoding of speech sounds in both groups. The ASD group further demonstrated less robust neural representation of spectral properties of speech sounds. Associations between neural processing of speech sounds and language-related abilities were evident in both groups. Parent-child associations were also detected in neural pitch processing. Together, results suggest that atypical neural processing of speech sounds is a heritable ingredient contributing to the ASD language phenotype.
