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.

Sympathetic nervous system functioning during the face-to-face still-face paradigm in the first year of life / Louis KLEIN in Development and Psychopathology, 35-2 (May 2023)

To understand infants' potential risk for emergent psychopathology, consideration is needed to both autonomic reactivity and environmental contexts (e.g., parent-child interactions). The current study maps infants' arousal during the face-to-face still-face paradigm using skin conductance (n = 255 ethnically-diverse mother-infant dyads; 52.5% girls, mean infant age = 7.4 months; SD = 0.9 months). A novel statistical approach was designed to model the potential build-up of nonlinear counter electromotive force over the course of the task. Results showed a significant increase in infants' skin conductance between the Baseline Free-play and the Still-Face phase, and a significant decrease in skin conductance during the Reunion Play when compared to the Still-Face phase. Skin conductance during the Reunion Play phase remained significantly higher than during the Baseline Play phase; indicating that infants had not fully recovered from the mild social stressor. These results further our understanding of infant arousal during dyadic interactions, and the role of caregivers in the development of emotion regulation during infancy.

Onset of substance use: Deviant peer, sex, and sympathetic nervous system predictors / J. Benjamin HINNANT in Development and Psychopathology, 34-4 (October 2022)

Community-sampled adolescents (N = 251; M = 15.78 years; 53% female; 66% White, 34% Black) participated in three waves. PEP reactivity was collected during a mirror star-tracer stress task. Alcohol, marijuana, tobacco, or any substance use, as well as binge drinking and sexual activity involving substance use were outcomes predicted by affiliation with deviant peers and two- and three-way interactions with sex and PEP reactivity. Probability of substance use increased over time, but this was amplified for adolescents with greater deviant peer affiliation in conjunction with blunted PEP reactivity. The same pattern of results was also found for prediction of binge drinking and sexual activity involving substance use. Findings are discussed in the context of biosocial models of adolescent substance use and health risk behaviors.

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)

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.

Developmental consequences of early life stress on risk for psychopathology: Longitudinal associations with children's multisystem physiological regulation and executive functioning / Kristen L. RUDD in Development and Psychopathology, 33-5 (December 2021)

BUSH, Auteur Article en page(s) : p.1759-1773 Langues : Anglais (eng) Mots-clés : early adversity  executive functioning  HPA axis  parasympathetic nervous system  sympathetic nervous system Index. décimale : PER Périodiques Résumé : The etiology of psychopathology is multifaceted and warrants consideration of factors at multiple levels and across developmental time. Although experiences of adversity in early life have been associated with increased risk of developing psychopathology, pathways toward maladaptation or resilience are complex and depend upon a variety of factors, including individuals’ physiological regulation and cognitive functioning. Therefore, in a longitudinal cohort of 113 mother–child dyads, we explored associations from early adverse experiences to physiological coregulation across multiple systems and subsequent variations in executive functioning. Latent profile analysis derived multisystem profiles based on children's heart rate, respiratory sinus arrhythmia, pre-ejection period, and cortisol measured during periods of rest and reactivity throughout a developmentally challenging protocol. Three distinct profiles of multisystem regulation emerged: heightened multisystem baseline activity (anticipatory arousal/ autonomic nervous system [ANS] responder), typically adaptive patterns across all systems (active copers/mobilizers), and heightened hypothalamic–pituitary–adrenal (HPA) axis activity (HPA axis responders). Path models revealed that children exposed to adversity before 18 months were more likely to evidence an anticipatory arousal/ANS responders response at 36 months, and children in this profile had lower executive functioning scores than the active copers/mobilizers. In sum, these findings provide important information about potential physiological associations linking early adversity to variations in children's task-based executive functioning.
