Atypical autonomic nervous system complexity accompanies social cognition task performance in ASD / Hamidreza SAGHIR in Research in Autism Spectrum Disorders, 39 (July 2017)  

Public ISBD [article]  inResearch in Autism Spectrum Disorders > 39 (July 2017) . - p.54-62 Titre : Atypical autonomic nervous system complexity accompanies social cognition task performance in ASD Type de document : Texte imprimé et/ou numérique Auteurs : Hamidreza SAGHIR, Auteur ; Annie DUPUIS, Auteur ; Tom CHAU, Auteur ; Azadeh KUSHKI, Auteur Article en page(s) : p.54-62 Langues : Anglais (eng) Mots-clés : Autism spectrum disorder  Autonomic nervous system  Complexity analysis  Social cognition  RMET  Theory of mind  ASD in children Index. décimale : PER Périodiques Résumé : AbstractBackground Emerging evidence suggests that autonomic nervous system (ANS) function is affected in ASD. Existing literature has focused on quantifying the activity of ANS components (i.e. sympathetic/parasympathetic systems) individually. To this end, measures such as respiratory sinus arrhythmia (RSA) and high- and low-frequency spectral components of heart rate variability have been employed. Recent findings indicate that these methods employ assumptions that do not fully consider the complexity of the ANS system and the interaction of its components. To this end, we propose a new method for examining ANS function in ASD. Methods A sample of typically developing (TD) children (n = 34) and children with ASD (n = 45) performed the Reading the Mind in the Eyes Task (RMET), preceded and followed by periods of baseline movie-watching. Multiscale Entropy (MSE) was employed as a new tool to examine the complexity of the cardiac signal. Results Significant group differences in MSE emerged to suggest atypicality in the regularity of the autonomic signal at short and long time scales in the ASD group during the RMET task. Conclusions For the RMET task, our results may suggest atypical activation of parasympathetic influences on the heart, which contributes to short-term patterns in the heartbeat signal, as well as atypicalities in the slower acting processes. Results also suggest that the coupling between the fast-acting and slow-acting influences may be atypical in ASD during the examined social cognition task.

Patterns of Sensitivity to Emotion in Children with Williams Syndrome and Autism: Relations Between Autonomic Nervous System Reactivity and Social Functioning / Anna JÄRVINEN in Journal of Autism and Developmental Disorders, 45-8 (August 2015)

Affective visual stimuli were used to assess autonomic reactivity and emotion identification, and the social responsiveness scale was used to determine the level social functioning in children with WS and ASD contrasted with typical development (TD), to examine syndrome-specific and syndrome-general features. Children with ASD exhibited the highest arousal in response to faces, with a lack of difference in autonomic sensitivity across different emotional expressions, unlike in WS and TD. The WS group demonstrated unique deficits in identifying neutral stimuli. While autonomic responsivity to neutral faces was associated with social functioning in all children, converging profiles characterized children with WS contrasted with TD and ASD.

Sympathetic nervous system dominance during stress recovery mediates associations between stress sensitivity and social anxiety symptoms in female adolescents / Tiffany C. HO in Development and Psychopathology, 32-5 (December 2020)

No study, however, has systematically examined which aspects of autonomic nervous system function mediate likely links between stress sensitivity and social anxiety symptoms in adolescents. Here, we assessed 163 adolescents (90 females; 12.29 ± 1.39 years) with respect to life stress and social anxiety symptoms, and measured respiratory sinus arrhythmia (RSA) and skin conductance levels (SCL) during a psychosocial stress paradigm. We operationalized stress sensitivity as the residual variance in subjective stress severity after accounting for objective severity and changes in autonomic regulation using standardized change scores in RSA and SCL. In females only, stress sensitivity and social anxiety symptoms were significantly correlated with each other (p < .001) and with autonomic regulation during both reactivity and recovery (all ps < 0.04). Further, sympathetic nervous system dominance during recovery specifically mediated associations between stress sensitivity and social anxiety symptoms (B = 1.06, 95% CI: 0.02-2.64). In contrast, in males, stress sensitivity, autonomic regulation during reactivity or recovery, and social anxiety symptoms were not significantly associated (all ps > 0.1). We interpret these results in the context of psychobiological models of SAD and discuss implications for interventions targeting autonomic processes.

Autonomic Dysregulation During Sensory Stimulation in Children with Autism Spectrum Disorder / Roseann C. SCHAAF in Journal of Autism and Developmental Disorders, 45-2 (February 2015)  

Public ISBD [article]  inJournal of Autism and Developmental Disorders > 45-2 (February 2015) . - p.461-472 Titre : Autonomic Dysregulation During Sensory Stimulation in Children with Autism Spectrum Disorder Type de document : Texte imprimé et/ou numérique Auteurs : Roseann C.

SENDECKI, Auteur Article en page(s) : p.461-472 Langues : Anglais (eng) Mots-clés : Autism spectrum disorders  Sensation  Autonomic nervous system  Parasympathetic nervous system  Sympathetic nervous system Index. décimale : PER Périodiques Résumé : Autonomic nervous system (ANS) activity during sensory stimulation was measured in 59 children with autism spectrum disorder (ASD) ages 6–9 in comparison to 30 typically developing controls. Multivariate comparisons revealed significant differences between groups in the respiratory sinus arrhythmia (parasympathetic measure) vector of means across sensory stimuli (p = 0.02) and in change from domain to domain (p = 0.01). Sympathetic activity, measured by pre-ejection period, did not differ significantly between groups, although it was higher in ASD participants. Findings suggest that participants with ASD demonstrated a different pattern of parasympathetic activity during sensory stimulation. Findings are discussed in relation to the biological mechanisms of sensory processing in autism, insight into the autism phenotype, and the utility of ANS activity as an outcomes marker.

Autonomic complexity and emotion (dys-)regulation in early childhood across high- and low-risk contexts / Daniel BERRY in Development and Psychopathology, 31-3 (August 2019)

These processes are supported by the engagement of the autonomic nervous system (ANS), a physiological hub of a vast network tasked with dynamically integrating real-time experiential inputs with internal motivational and goal states. To date, much of what is known about the ANS and emotion regulation has been based on measures of respiratory sinus arrhythmia, a cardiac indicator of parasympathetic activity. In the present study, we draw from dynamical systems models to introduce two nonlinear indices of cardiac complexity (fractality and sample entropy) as potential indicators of these broader ANS dynamics. Using data from a stratified sample of preschoolers living in high- (i.e., emergency homeless shelter) and low-risk contexts (N = 115), we show that, in conjunction with respiratory sinus arrhythmia, these nonlinear indices may help to clarify important differences in the behavioral manifestations of emotion regulation. In particular, our results suggest that cardiac complexity may be especially useful for discerning active, effortful emotion regulation from less effortful regulation and dysregulation.
