Autonomic nervous system responses to social stimuli among autistic individuals: A systematic review and meta-analysis / Ester ZADOK in Autism Research, 17-3 (March 2024)  

Public ISBD [article]  inAutism Research > 17-3 (March 2024) . - p.497-511 Titre : Autonomic nervous system responses to social stimuli among autistic individuals: A systematic review and meta-analysis Type de document : texte imprimé Auteurs : Ester ZADOK, Auteur ; Ofer GOLAN, Auteur ; Michal LAVIDOR, Auteur ; Ilanit GORDON, Auteur Article en page(s) : p.497-511 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : Abstract Physiological responses to environmental and social stimuli have been studied broadly in relation to psychological states and processes. This may be especially important regarding autistic individuals, who show disparities in social interactions. However, findings from studies assessing autonomic nervous system (ANS) responses of autistic individuals present contradictions, with reports showing both autonomic disparities and intact autonomic functioning. The current study aimed to review the existing literature and to estimate if there is a difference between autistic individuals and neurotypical (NT) individuals in their autonomic responses to social stimuli. Furthermore, the study examined factors that may moderate this difference, including the type of physiological function measured, the level of participation required, as well as the age and intellectual functioning of the participants. The meta-analysis revealed a small and statistically insignificant overall difference between autistic and NT individuals, albeit with high heterogeneity. A further nested moderator analysis revealed a significant difference between autistic and NT individuals in physiological response that reflects mainly a parasympathetic nervous system (PNS) activity. Another difference was found in physiological response that reflects a combined activity of the sympathetic and parasympathetic systems, but only for experimental tasks that demanded active participation in social interactions. These results suggest a distinctiveness in autonomic regulation of autistic individuals in social situations, and point to the PNS as an important study objective for future investigation.

Empathic Behavior and Behavioral Synchrony During Video Conversations in Autistic and Non-autistic Adolescents / Ester ZADOK in Journal of Autism and Developmental Disorders, 56-12 (December 2026)  

Public ISBD [article]  inJournal of Autism and Developmental Disorders > 56-12 (December 2026) . - p.4742-4756 Titre : Empathic Behavior and Behavioral Synchrony During Video Conversations in Autistic and Non-autistic Adolescents Type de document : texte imprimé Auteurs : Ester ZADOK, Auteur ; Zohar BEN-MOSHE, Auteur ; Ilanit GORDON, Auteur ; Ofer GOLAN, Auteur Article en page(s) : p.4742-4756 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : Behavioral synchrony is an important component of successful social interaction. Synchronization of facial expressions during interaction is considered a facilitator of empathic behavior. Autistic individuals show alterations in synchronous and empathic behaviors. Yet, an ecological examination of these among adolescents is needed. Through a video-based platform, we employed a social interaction sequence with a nonautistic confederate that included a friendly conversation and an expression of discouragement. 50 male adolescents (23 autistic) participated. Socio-emotional behaviors, assessed by naïve trained raters and by automated measure of facial expressions, were analyzed. Results indicated reduced synchrony in interactions with autistic adolescents, compared to non-autistic adolescents, as well as fewer empathic behaviors. Participants’ emotion recognition abilities did not account for these differences. Our findings point to the central role of behavioral synchrony in the social disparities autistic adolescents often experience.

Shifts in Behavioral Synchrony in Response to an Interaction Partner's Distress in Adolescents With and Without ASD / Ester ZADOK in Journal of Autism and Developmental Disorders, 52-10 (October 2022)  

Public ISBD [article]  inJournal of Autism and Developmental Disorders > 52-10 (October 2022) . - p.4261-4273 Titre : Shifts in Behavioral Synchrony in Response to an Interaction Partner's Distress in Adolescents With and Without ASD Type de document : texte imprimé Auteurs : Ester ZADOK, Auteur ; Ilanit GORDON, Auteur ; Roni NAVON, Auteur ; Shai Joseph RABIN, Auteur ; Ofer GOLAN, Auteur Article en page(s) : p.4261-4273 Langues : Anglais (eng) Mots-clés : Adolescence  Autism spectrum disorder  Behavioral synchrony  Motion energy analysis  Prosocial behavior Index. décimale : PER Périodiques Résumé : Individuals with Autism spectrum disorder (ASD) show altered behavioral synchrony and empathic behavior. Yet, an ecologically valid examination of these in adolescents is still required. We employed a social interaction sequence comprising a friendly conversation with a confederate, an expression of distress by her, and a return to friendly conversation. 44 male adolescents (22 with ASD) participated. Socio-emotional behaviors, coded by blind raters and through automated analyses of motion, were analyzed. Results indicated reduced synchrony in the ASD group. Moreover, whereas controls displayed a decrease in synchrony when facing another's distress, adolescents with ASD showed no such change. No group differences were found on empathic behavior. Findings imply gaps between verbal and non-verbal responses of adolescents with ASD to a distressed interaction partner.
