Atypicalities of Gesture Form and Function in Autistic Adults / A. DE MARCHENA in Journal of Autism and Developmental Disorders, 49-4 (April 2019)
[article]
Titre : Atypicalities of Gesture Form and Function in Autistic Adults Type de document : Texte imprimé et/ou numérique Auteurs : A. DE MARCHENA, Auteur ; E. S. KIM, Auteur ; A. BAGDASAROV, Auteur ; Julia PARISH-MORRIS, Auteur ; B. B. MADDOX, Auteur ; Edward S. BRODKIN, Auteur ; Robert T. SCHULTZ, Auteur Article en page(s) : p.1438-1454 Langues : Anglais (eng) Mots-clés : Adulthood Autism spectrum disorder Conversation Gesture Motor skills Nonverbal communication Index. décimale : PER Périodiques Résumé : While well-represented on clinical measures, co-speech gesture production has never been formally studied in autistic adults. Twenty-one verbally fluent autistic adults and 21 typically developing controls engaged in a controlled conversational task. Group differences were observed in both semantic/pragmatic and motoric features of spontaneously produced co-speech gestures. Autistic adults prioritized different functions of co-speech gesture. Specifically, they used gesture more than controls to facilitate conversational turn-taking, demonstrating a novel nonverbal strategy for regulating conversational dynamics. Autistic adults were more likely to gesture unilaterally than bilaterally, a motoric feature of gesture that was individually associated with autism symptoms. Co-speech gestures may provide a link between nonverbal communication symptoms and known differences in motor performance in autism.

Titre : The first five minutes: Initial impressions during autism spectrum disorder diagnostic evaluations in young children Type de document : Texte imprimé et/ou numérique Auteurs : A. T. WIECKOWSKI, Auteur ; A. DE MARCHENA, Auteur ; Y. ALGUR, Auteur ; L. NICHOLS, Auteur ; S. FERNANDES, Auteur ; R. P. THOMAS, Auteur ; L. A. MCCLURE, Auteur ; S. DUFEK, Auteur ; Deborah A. FEIN, Auteur ; Lauren B. ADAMSON, Auteur ; A. STAHMER, Auteur ; Diana L. ROBINS, Auteur Article en page(s) : p.1923-1934 Langues : Anglais (eng) Mots-clés : Autism Spectrum Disorder/diagnosis Autistic Disorder Child Child, Preschool Early Diagnosis Family Humans autism spectrum disorder clinician confidence in diagnosis diagnosis early detection initial impression toddlers Index. décimale : PER Périodiques Résumé : Diagnosticians report that autism spectrum disorder (ASD) is immediately apparent in some, but not all, children ultimately diagnosed. Clinicians' initial diagnostic impressions have implications for ASD early detection, yet the literature raises questions about their accuracy. This study explores diagnostic impressions of ASD specialists made within the first 5?minutes of meeting a young child and investigates factors associated with the match between initial impressions and final diagnoses. Participants were children (n = 294, aged 12-53?months) referred for an ASD evaluation as part of multi-site ASD screening studies. After 5?minutes observing each child, clinicians with expertise diagnosing ASD recorded if they thought the child would meet criteria for ASD following a complete evaluation, and recorded their confidence in this impression. Clinicians' initial impressions matched the final diagnosis in 81% of cases. Ninety-two percent of cases initially thought to have ASD met criteria following a full evaluation; however, 24% of cases initially thought not to have ASD also met criteria, suggesting a high miss rate. Clinicians were generally confident in their initial impressions, reporting highest confidence for children initially thought correctly not to have ASD. ASD behavioral presentation, but not demographic characteristics or developmental level, were associated with matching initial impression and final diagnosis, and confidence. Brief observations indicating ASD should trigger referral to intervention services, but are likely to under-detect positive cases and should not be used to rule out ASD, highlighting the need to incorporate information beyond initial clinical impression. LAY SUMMARY: When children come in for an autism evaluation, clinicians often form early impressions-before doing any formal testing-about whether the child has autism. We studied how often these early impressions match the final diagnosis, and found that clinicians could not easily rule out autism (many children who initially appeared not to have autism were ultimately diagnosed), but were generally accurate ruling in autism (when a child appeared to have autism within 5?minutes, they were almost always so diagnosed).
