DENVER, Auteur Année de publication : 2010 Article en page(s) : p.358-370 Langues : Anglais (eng) Mots-clés : Autism Emotion-recognition Eye-gaze RSA Social-engagement Polyvagal-Theory Index. décimale : PER Périodiques Résumé : Respiratory Sinus Arrhythmia (RSA), heart rate, and accuracy and latency of emotion recognition were evaluated in children with autism spectrum disorders (ASD) and typically developing children while viewing videos of faces slowly transitioning from a neutral expression to one of six basic emotions (e.g., anger, disgust, fear, happiness, sadness, and surprise). Children with ASD were slower in emotion recognition and selectively made more errors in detecting anger. ASD children had lower amplitude RSA and faster heart rate. Within the ASD group, children with higher amplitude RSA recognized emotions faster. Less severe ASD symptoms and increased gaze to the eye region in children with ASD were related to more accurate emotion recognition.

Sluggish vagal brake reactivity to physical exercise challenge in children with selective mutism / Keri J. HEILMAN in Development and Psychopathology, 24-1 (January 2012)  

Public ISBD [article]  inDevelopment and Psychopathology > 24-1 (January 2012) . - p.241-250 Titre : Sluggish vagal brake reactivity to physical exercise challenge in children with selective mutism Type de document : Texte imprimé et/ou numérique Auteurs : Keri J. HEILMAN, Auteur ; Sucheta D. CONNOLLY, Auteur ; Wendy O. PADILLA, Auteur ; Marika I. WRZOSEK, Auteur ; Patricia A. GRACZYK, Auteur ; Stephen W. PORGES, Auteur Année de publication : 2012 Article en page(s) : p.241-250 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : Cardiovascular response patterns to laboratory-based social and physical exercise challenges were evaluated in 69 children and adolescents, 20 with selective mutism (SM), to identify possible neurophysiological mechanisms that may mediate the behavioral features of SM. Results suggest that SM is associated with a dampened response of the vagal brake to physical exercise that is manifested as reduced reactivity in heart rate and respiration. Polyvagal theory proposes that the regulation of the vagal brake is a neurophysiological component of an integrated social engagement system that includes the neural regulation of the laryngeal and pharyngeal muscles. Within this theoretical framework, sluggish vagal brake reactivity may parallel an inability to recruit efficiently the structures involved in speech. Thus, the findings suggest that dampened autonomic reactivity during mobilization behaviors may be a biomarker of SM that can be assessed independent of the social stimuli that elicit mutism.
