ABSTRACT
How does empathic physiology unfold as a dynamic process, and which aspect of empathy predicts children's kindness? In response to empathy induction videos, 4- to 6-year-old children (N = 180) showed an average pattern of dynamic respiratory sinus arrhythmia (RSA) change characterized by early RSA suppression, followed by RSA recovery, and modest subsequent suppression during positive resolution of the empathic event. Children's capacity for this pattern of flexible RSA change was associated with their subjective empathic feelings, which were concurrently associated with more sympathetic and prosocial responses to others. Conversely, only children's dynamic RSA change longitudinally predicted prosocial behavior 2 years later. These findings have implications for understanding the dynamic and multifaceted nature of empathy, and its relation with prosocial development.

Parasympathetic regulation and maternal overprotective parenting were examined in 101 children as moderators of links between preschool (M = 3.53 years) social wariness and childhood (M = 9.07 years) internalizing and anxiety problems, social skills, and scholastic performance. Across these three domains of functioning, more socially wary children were likely to manifest worse adjustment when they had low respiratory sinus arrhythmia (RSA) or highly overprotective mothers. Conversely, maternal overprotection appeared to confer benefits for preschoolers with low wariness and low RSA. These findings point to the importance of both internal self-regulatory capacities and external support for autonomy and competence to understand and assist socially wary children and their families.

Polyvagal theory provides a framework for understanding connections between children's autonomic regulation, cognitive functioning, and behavioral adjustment. Parasympathetic regulation has been associated with executive functions and externalizing problems (EP), and children with EP demonstrate deficits in inhibition of prepotent responding, or inhibitory control (IC). We examined parasympathetic regulation of cardiac reactivity during two IC tasks in 144 children (M = 5.61 years, SD = 1.09) ranging from low to clinical levels of EP. Overall children with more EP evidenced greater RSA suppression during IC tasks than did children with fewer EP, and degree of RSA suppression also moderated associations between IC performance and EP. Only for children who showed stronger RSA suppression was accuracy of IC response inversely associated with EP, and latency of response for one task positively associated with EP. This study provides insight into the role of parasympathetic mechanisms in children's cognitive regulation of impulsive and aggressive behaviors.

This study examined the moderating effects of child temperament on the association between maternal socialization and 4-6-year-old children's dynamic respiratory sinus arrhythmia (RSA) change in response to anger-themed emotional materials (N=180). We used latent growth curve modeling to explore adaptive patterns of dynamic RSA change in response to anger. Greater change in RSA during anger-induction, characterized by more initial RSA suppression and a subsequent return to baseline, was related to children's better regulation of aggression. For anger-themed materials, low levels of authoritarian parenting predicted more RSA suppression and recovery for more anger-prone children, whereas more authoritative parenting predicted more RSA suppression and recovery for less anger-prone children. These findings suggest that children's adaptive patterns of dynamic RSA change can be characterized by latent growth curve modeling, and that these patterns may be differentially shaped by parent socialization experiences as a function of child temperament.

BACKGROUND: Effective emotion regulation should be reflected in greater coherence between physiological and subjective aspects of emotional responses. METHOD: Youths with normative to clinical levels of internalizing problems (IP) and externalizing problems (EP) watched emotionally evocative film-clips while having heart rate (HR) recorded, and reported subjective feelings. RESULTS: Hierarchical linear modeling revealed weaker coherence between HR and negative feelings in youths, especially boys, with more EP. Youths with IP showed coherence between HR and negative feelings that did not match the affect portrayed in the eliciting stimuli, but atypical positive emotions: they felt happier when they had slower HR. Youths without problems predominantly showed normative emotional coherence. CONCLUSIONS: Youths with EP and IP experience atypical patterns of activation across physiological and experiential emotion systems which could undermine emotion regulation in evocative situations.

Effective emotion regulation is essential for children's positive development. Polyvagal theory provides a framework for understanding how parasympathetic regulation of cardiac activity contributes to children's adaptive versus maladaptive functioning. Maintenance of cardiac respiratory sinus arrhythmia (RSA) under social challenge should support emotion regulation and behavioral adjustment. Children's effective parasympathetic regulation and behavioral adjustment should be supported by appropriate parental socialization. These proposals were evaluated in a short-term longitudinal study of 94 preschool-aged children. Parenting and basal RSA were measured at home, then 6-10 months later behavioral adjustment and RSA in lab baseline and socially challenging contexts were measured. Children with relatively higher RSA in social challenge than at baseline (DeltaRSA) had fewer internalizing problems (IP) and externalizing problems (EP), and better behavioral self-regulation (SR). Mothers who used more negative control had children with lower DeltaRSA, more IP and EP, and less SR. Structural equation modeling showed that vagal regulation mediated associations between maternal negative control and children's adjustment; maternal negative control did not predict EP or SR after accounting for DeltaRSA. Associations were consistent across boys and girls, with one exception: Higher DeltaRSA was significantly associated with fewer EP in boys only. These findings suggest that the practical significance of physiological regulation might be best revealed in ecologically valid procedures, and that children's physiological mechanisms of emotion regulation are shaped by their experiences of parental socialization.
