Thus, the observation of others' facial expressions activates the same neural representation of that affective state in the observer, along with related autonomic and somatic responses. What happens, therefore, when someone cannot mimic others' facial expressions? METHODS: We investigated whether psychophysiological emotional responses to others' facial expressions were impaired in 13 children (9 years) with Moebius syndrome (MBS), an extremely rare neurological disorder (1/250,000 live births) characterized by congenital facial paralysis. We inspected autonomic responses and vagal regulation through facial cutaneous thermal variations and by the computation of respiratory sinus arrhythmia (RSA). These parameters provide measures of emotional arousal and show the autonomic adaptation to others' social cues. Physiological responses in children with MBS were recorded during dynamic facial expression observation and were compared to those of a control group (16 non-affected children, 9 years). RESULTS: There were significant group effects on thermal patterns and RSA, with lower values in children with MBS. We also observed a mild deficit in emotion recognition in these patients. CONCLUSION: Results support "embodied" theory, whereby the congenital inability to produce facial expressions induces alterations in the processing of facial expression of emotions. Such alterations may constitute a risk for emotion dysregulation.

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.
