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.

Evaluating Sensory Processing in Fragile X Syndrome: Psychometric Analysis of the Brain Body Center Sensory Scales (BBCSS) / Jacek KOLACZ in Journal of Autism and Developmental Disorders, 48-6 (June 2018)

However, sensory processing measures informed by neurophysiology are lacking. This paper describes the development and psychometric properties of a parent/caregiver report, the Brain-Body Center Sensory Scales (BBCSS), based on Polyvagal Theory. Parents/guardians reported on 333 individuals with FXS, 41% with ASD features. Factor structure using a split-sample exploratory-confirmatory design conformed to neurophysiological predictions. Internal consistency, test-retest, and inter-rater reliability were good to excellent. BBCSS subscales converged with the Sensory Profile and Sensory Experiences Questionnaire. However, data also suggest that BBCSS subscales reflect unique features related to sensory processing. Individuals with FXS and ASD features displayed more sensory challenges on most subscales.

Impact trajectories of childhood maltreatment duration on affective and social development / Martina ARDIZZI in Development and Psychopathology, 37-3 (August 2025)  

Public ISBD [article]  inDevelopment and Psychopathology > 37-3 (August 2025) . - p.1405-1415 Titre : Impact trajectories of childhood maltreatment duration on affective and social development Type de document : texte imprimé Auteurs : Martina ARDIZZI, Auteur ; Roberto RAVERA, Auteur ; Maria Alessandra UMILTÀ, Auteur ; Francesca FERRONI, Auteur ; Silvia AMPOLLINI, Auteur ; Jacek KOLACZ, Auteur ; Stephen W. PORGES, Auteur ; Vittorio GALLESE, Auteur Article en page(s) : p.1405-1415 Langues : Anglais (eng) Mots-clés : Autonomic regulation  duration  emotions  facial mimicry  maltreatment Index. décimale : PER Périodiques Résumé : Childhood maltreatment (CM) deeply impacts victims' social competences. The aim of the present study was to investigate the effect that CM duration exerts on victims' affective and social development testing three different impact trajectories (i.e., linear, logarithmic and quadratic) and its physiological (facial mimicry and autonomic regulation of the heart) and behavioral (percentage of anger recognition false alarm) markers. In a cross-sectional design, 73 Sierra Leonean youths (all males, 5-17 years old) were enrolled in the study. Of those, 36 were homeless all abandoned at the age of 4 and exposed to CM, whereas 37 were controls. Only physiological markers of affective development were influenced by CM duration. A quadratic relation between the autonomic regulation recorded at rest and CM duration was found, indicating initial physiological compensation followed by progressive autonomic withdrawal. Furthermore, CM duration was associated to a specific linear decrease of facial mimicry and vagal regulation in response to angry and sad facial expressions whereas no influences were detected for happy and fearful faces. The results of the present study provide insightful clues on victims' natural patterns of resilience, deterioration, and chronicity, allowing a deeper comprehension of the developmental pathways through which early life adversities place youths on a track of lifelong health disparities.

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

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.
