Marital conflict and trajectories of adolescent adjustment: The role of autonomic nervous system coordination

The interactive roles of narrative processing and emotion negativity/lability in relation to autonomic coordination

Emotion regulation (ER) is a multifaceted construct, involving behavioral, cognitive, and physiological processes. Although autonomic coordination is theorized to play a crucial role in adaptive functioning, few studies have examined how different individual and contextual factors together may contribute to such coordination. This study examined the joint influences of narrative processing and emotional negativity/lability (N/L) traits on the coordination of the sympathetic and parasympathetic nervous systems in a sample of 112 children, ages 8-12 years (Mage = 10.15 years, SD = 1.33). Children completed a stress-induction task followed by an interview about the task. Children's trait-level N/L was assessed via parent-report on the Emotion Regulation Checklist. Narrative processing was assessed and coded based on children's narrative accounts of the event (i.e., causal coherence, overall emotional tone). Indexes of sympathetic (skin conductance response, SCR) and parasympathetic (respiratory sinus arrhythmia, RSA) functioning were derived from physiological data obtained during the interview. Results revealed that children's trait-level N/L and narrative processing of the stressful event interacted to predict the RSA-SCR correlation. Specifically, children who were high on either N/L or narrative causal coherence, but not both, demonstrated significant RSA-SCR correlation. Similarly, children with high N/L and negative-to-neutral narratives, as well as those with low N/L and neutral-to-positive narratives, exhibited significant RSA-SCR correlation. This work provides empirical evidence that narrative processing and trait N/L, together with RSA-SCR correlation, work in tandem to regulate emotional arousal.

Is autonomic functioning distinctly associated with anxiety and unsociability in preschoolers?

There are many benefits of peer interactions for children's social, emotional, and cognitive development, and isolation from peers may have negative consequences for children. Although biological processes may underlie social withdrawal broadly, distinct patterns may be associated with withdrawal behaviors depending on their underlying motivation (e.g., shy versus disinterested). This study investigated the role of autonomic nervous system activity, as assessed via skin conductance level (SCL) and respiratory sinus arrhythmia (RSA) in predicting changes in unsociability (e.g., lack of interest in peers) and anxious-fearfulness (e.g., discomfort among peers). Data were collected using a community sample of 92 US preschool children (45.7% female; Mage = 45.51 months, SDage = 3.81 months) at two time points one year apart. Gender differences were also explored. Baseline physiology was assessed while viewing a neutral video clip, and reactivity was assessed while viewing social exclusion and post-aggression discussion videos. For all children, coinhibition (i.e., SCL inhibition accompanied by RSA inhibition) to the post-aggression discussion video and blunted SCL activation to the exclusion video were prospectively associated with higher levels of anxious-fearfulness one year later. For boys only, baseline reciprocal sympathetic activation (i.e., SCL activation and RSA inhibition) was prospectively related to higher levels of unsociability one year later. For girls only, RSA inhibition in response to the post-aggression discussion video was prospectively related to higher levels of unsociability one year later. Findings contribute to a growing literature on autonomic reactivity in preschoolers' adjustment and suggest possible differences in the physiological processes underlying unsociability and anxious-fearfulness.

Reciprocal relations between interparental aggression and symptoms of oppositional defiant and conduct disorders: a seven-wave cohort study of within-family effects from preschool to adolescence

BACKGROUND

Interparental aggression is believed to increase the risk of behavioral disorders in offspring, and offspring behavioral problems may forecast interparental aggression. However, these assumptions have yet to be put to a strong test. This study, therefore, examined whether increased interparental aggression predicted increased symptoms of oppositional defiant disorder (ODD) and conduct disorder (CD) from preschool to adolescence and vice versa.

METHODS

A sample (n = 1,077; 49.6% girls) from two birth cohorts of children in Trondheim, Norway, was assessed biennially from age 4 to 16. Children's symptoms of ODD and CD were assessed using semi-structured clinical interviews of parents (from age 4) and children (from age 8). One of the parents reported on their own and their partner's verbal and physical aggression. A random intercept cross-lagged model was estimated to test the within-family relations between interparental aggression, CD, and ODD symptoms.

RESULTS

Across development, increased interparental aggression predicted increased CD symptoms 2 years later, whereas an increased number of ODD symptoms forecasted increased interparental aggression.

CONCLUSIONS

The argumentative/defiant, aggressive, and vindictive behaviors seen in ODD are often directed toward parents and may take a toll on their relationship and possibly foster interparental aggression, whereas aggression between parents may promote symptoms of CD in their offspring, which commonly extend beyond the home. Incorporating effective and non-aggressive means to solve interparental conflict into parental management programs may reduce the development of symptoms of CDs in children.

Autonomic nervous system reactivity to emotion and childhood trajectories of relational and physical aggression

This study investigated the role of autonomic nervous system (ANS) coordination in response to emotion in girls' and boys' development of relational (e.g., ignoring, excluding) and physical (e.g., hitting, kicking) aggression. Caregivers reported on children's relational and physical aggression at ages 6, 7, 8, and 10 years (N = 232, 50.4% girls, 46.6% Latinx). Sympathetic nervous system (assessed via pre-ejection period) and parasympathetic nervous system (assessed via respiratory sinus arrhythmia) reactivity were measured in response to video clips depicting fear, happiness, and sadness at age 7. Growth curve models indicated that ANS reactivity to sadness, but not to fear or happiness, was related to trajectories of relational aggression. In contrast, ANS reactivity to all three emotions was associated with trajectories of physical aggression. Effects differed across genders, indicating that distinct patterns of ANS reactivity to emotion may be involved in girls' and boys' development of aggression. Overall, these findings contribute to a growing literature documenting the role of ANS reactivity to emotion in aggressive behavior. Moreover, this study considers ANS reactivity to specific emotions, as related to both relational and physical aggression, and as differentially expressed among girls versus boys.

An integrated model: marital effect on adolescent behavioral problems through siblings

Introduction

Few studies have simultaneously focused on the effects of marital conflict and marital intimacy on adolescent development, and little is known about the role of sibling relationships. Thus, this study examined the association between marital relationships and adolescent behavioral problems, including depressive symptoms and aggressive behavior. At the same time, we explored the mediating role of sibling hostility and sibling affection and the moderating effect of birth order in multichild families in China.

Methods

Participants included 842 adolescents (Mage = 12.60, 46.2% boys) from Henan Province. Marital relationship, sibling relationship, birth order, depressive symptoms and aggressive behavior were assessed by a self-administered questionnaire. SEM was then used to examine the role of sibling relationships and birth order in the association between marital relationship and adolescent behavioral problems.

Results

Our results showed that marital intimacy was negatively correlated with depressive symptoms and aggressive behavior, while marital conflict was positively correlated with them. Marital intimacy was associated with depressive symptoms and aggressive behavior through both sibling hostility and sibling affection. Marital conflict was indirectly associated with depressive symptoms and aggressive behavior through sibling hostility. In addition, the first-born adolescents were more sensitive to marital intimacy.

Discussion

Given that the occurrence of adolescent behavioral problems is more common in contemporary society, our findings suggest that establishing a more intimate and warmer family atmosphere and promoting positive interactions between siblings may help control adolescent mental health problems.

Parent-Child Cohesion and College Students' Positive/Negative Affect: The Moderating Roles of Sympathetic Nervous System Activity and Parent-Child Separation Experience

Parent-child separation caused by parental migration could have adverse effects on individuals' emotional adaptation. However, research on this topic is limited in its focus on childhood or adolescence samples and solely environmental factors, and less is known about how positive environmental factors, biological factors and parent-child separation experience interact to influence emotional adaptation in emerging adulthood. The present study addressed these issues by investigating the relationships between parent-child cohesion and positive/negative affect, and examining the moderating roles of sympathetic nervous system activity (measured by skin conductance level reactivity, SCLR) and parent-child separation experience in the relationships. Data from 248 college students (M_age = 18.91 years, SD = 0.70; 32.3% males), including 158 college students with parent-child separation experience and 90 college students without parent-child separation experience. The results showed that parent-child cohesion predicted college students' positive/negative affect. Moreover, the moderating role of SCLR on the relationship between father-child cohesion and negative affect varied with parent-child separation experience. Specifically, father-child cohesion negatively predicted negative affect when SCLR was lower for college students with parent-child separation experience, while negatively predicted negative affect when SCLR was higher for college students without parent-child separation experience. These results indicate that the interaction pattern of Biological × Environmental predicting college students' positive/negative affect varies across parent-child separation status in childhood or adolescence.

Physiological reactivity to fear moderates the relation between parenting distress with conduct and prosocial behaviors

This study investigated whether the associations between parental distress with conduct problems (CPs) and prosocial behaviors (PBs) are moderated by children's skin conductance (SC) and heart rate (HR) reactivity to fear. Participants were 147 Greek-Cypriot children (M_age  = 7.30, 44.2% girls), selected from a larger screening sample (data were collected from 2015 to 2018). Longitudinal associations suggested that children with high HR reactivity to fear were more likely to display PB, whereas those with low SC reactivity were more likely to engage in CP behaviors. In contrast, interaction effects suggested that children high on SC reactivity to fear were more susceptible to the effects of parental distress, as indicated by their higher vulnerability to engage in CP (cross-sectionally) behaviors and their lower scores on PB (cross-sectionally and longitudinally).

The Role of Autonomic System Coordination in Relations Between Peer Factors and Aggressive Behavior in Early Childhood

This study tested biological sensitivity to context theory in the peer context. Respiratory sinus arrythmia (RSA-R) and skin conductance level (SCL-R) reactivity to a peer stressor were collected for participants (N = 86; M age = 45.99 months old; 70.2% White) in the summer (Time 1). Children's peer risk (i.e., physical and relational victimization) and protective (i.e., received prosocial behavior) factors were examined in the fall (T2) and relational and physical aggression were measured at T2 and in the spring (T3). Interactions were tested in regression analyses. Interactions emerged between relational victimization, RSA-R, and SCL-R in the prediction of T3 relational aggression and between received prosocial behavior, RSA-R, and SCL-R in the prediction of T3 relational and physical aggression, respectively. There was a positive relation between T2 relational victimization and T3 relational aggression for children with a coactivation pattern (i.e., increased RSA and SCL activity to a bullying stressor) but no relation for any other physiological pattern. Conversely, there was a negative relation between T2 received prosocial behavior and both forms of aggression at T3 for children with a reciprocal pattern (i.e., increased RSA and decreased SCL or decreased RSA and increased SCL activity) but no protective benefit of received prosocial behavior on subsequent aggression for children with a coactivation pattern. For children with a coinhibition pattern (i.e., decreased RSA and SCL activity), received prosocial behavior was negatively related to subsequent physical but not relational aggression. In sum, a coactivation pattern in response to stress may represent a vulnerability factor.

The moderating effect of marital conflict on the relationship between social avoidance and socio-emotional functioning among young children in suburban China

Social avoidance has been found to be related to negative social adjustment, yet evidence of the relationship between social avoidance and social adjustment is very limited in suburban preschoolers in China. Moreover, the underlying mechanisms that help to explain the associations between social avoidance and socio-emotional adjustment remain poorly considered. The goal of the present study was to examine the moderating effect of marital conflict in the link between social avoidance and indices of socio-emotional functioning among young children in mainland China. Participants were N = 256 children aged from 49 to 72 months (125 boys, 131 girls, M_age  = 59.06 months, SD = 6.58) attending preschools/kindergartens in suburban areas of Shanghai, People's Republic of China. Multi-source assessments were employed, with mothers reporting marital conflict as well as rating their children's social withdrawal (i.e., social avoidance, shyness, unsociability), and teachers assessing indices of children's socio-emotional functioning at school (i.e., anxious-fearful behavior, peer exclusion, and loneliness). Children were asked about their loneliness. Among the results, social avoidance was positively associated with anxious-fearful behavior, peer exclusion, and loneliness (marginal significance). Moreover, as hypothesized, marital conflict was found to exacerbate the relations between social avoidance and peer exclusion, and loneliness. Results are discussed in terms of the etiology and implications of social avoidance among young children in mainland China.

Childhood violence exposure and externalizing behaviors: A systematic review of the role of physiological biomarkers

Childhood exposure to violence has been consistently linked to externalizing behaviors like delinquency and aggression. Growing evidence indicates that physiological biomarkers from the parasympathetic and sympathetic nervous systems (PNS and SNS) and hypothalamic-pituitary-adrenal (HPA) axis may moderate or mediate the relation between childhood violence exposure and externalizing behaviors. We conducted a systematic review to synthesize recent findings on physiological biomarkers as mediators and/or moderators of this association across the life course, using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Our search yielded 3878 articles, of which 44 met inclusion criteria (describing a total of 46 independent studies). We found consistent evidence for blunted HPA-axis reactivity as a mediator of the relation between childhood violence exposure and subsequent externalizing behaviors, and for non-reciprocal PNS/SNS activation as moderators exacerbating this relation. However, the results of the majority of included studies that demonstrated significant moderating effects of physiological biomarkers varied by participant sex, type of childhood violence exposure, and type of stimuli used to induce physiological reactivity. The observed mixed findings are consistent with some theories that emphasize that both high and low stress reactivity can be adaptive depending on one's early environment. These findings highlight the need for systematic explorations of heterogeneity, theory-driven research questions, and longitudinal studies that span multiple developmental periods and multiple biological systems. Clinical implications include the need to assess physiological biomarkers in treatment and intervention studies and the potential to target interventions based on both autonomic functioning and environmental contexts.

Autonomic profiles and self-regulation outcomes in early childhood

This study examined autonomic profiles in preschoolers (N = 278, age = 4.7 years) and their relations to self-regulation outcomes concurrently and one year later, in kindergarten. Children's sympathetic (preejection period [PEP]) and parasympathetic activity (respiratory sinus arrythmia [RSA]) were measured at rest and during cognitive and emotional tasks. Three self-regulatory competencies were assessed: executive functions, emotion regulation and behavioral regulation. Executive functioning was measured at ages 4 and 5 using laboratory tasks designed to assess updating/working memory, inhibitory control, and cognitive flexibility. Emotion regulation was observed during emotionally distressing tasks in the laboratory, both at ages 4 and 5. Behavioral regulation and emotional reactivity were assessed via teacher ratings in kindergarten, at age 5. Latent profile analysis yielded four autonomic profiles: moderate parasympathetic inhibition (45%), reciprocal sympathetic activation (26%), coinhibition (25%), and high sympathetic activation (7%). The reciprocal sympathetic activation group showed better executive functioning in preschool and kindergarten, particularly compared to the high sympathetic activation group. The moderate parasympathetic inhibition group showed lower emotional reactivity and better behavioral regulation in kindergarten, compared to the other three groups. Findings suggest that autonomic profiles meaningfully associate with self-regulation outcomes in early childhood, such that certain profiles relate to better self-regulation than others.

Fathers’ parenting stress, parenting styles and children’s problem behavior: the mediating role of parental burnout

Parental duties can be overwhelming, particularly when parents lack sufficient resources to cope with parenting demands, leading to parental burnout. Research has shown that parental burnout is positively related to neglect and abuse behaviors towards their children; however, few studies have examined parental burnout within the family system, including examining parenting styles as an antecedent, and most research has ignored the potential influence of fathers’ parental burnout. This study aimed to explore the influence of fathers’ parenting stress and parenting styles on internalizing and externalizing problem behaviors in a sample of junior high school students and the mediating effect of parental burnout. Questionnaire data from 236 students (56.4% girls) and their fathers (age: M = 39.24, SD = 5.13) were collected on 3 different time points. Fathers were asked to report their parenting stress and parenting styles at Time 1, and parental burnout at Time 2, and students were asked to report their internalizing and externalizing behaviors at Time 3. The results indicated that: (1) fathers’ parenting stress and negative parenting styles were positively related to parental burnout, and fathers’ positive parenting styles were negatively related to parental burnout; (2) fathers’ parental burnout was positively related to children’s internalizing and externalizing problem behavior; and (3) fathers’ parental burnout could mediate the relationship between parenting stress, negative parenting styles, and internalizing and externalizing problem behavior. These results suggested that fathers’ roles in the parenting process were not negligible, and more attention should be given to prevention and intervention methods for fathers’ parental burnout.

Integrating dynamic and developmental time scales: Emotion-specific autonomic coordination predicts baseline functioning over time

Autonomic nervous system activity flexibly shifts and modulates behavior at multiple time scales, with some work suggesting that patterns of short-term reactivity contribute to long-term developmental change. However, previous work has largely considered sympathetic and parasympathetic systems independently, even though both systems contribute dynamically to the regulation of physiological arousal. Using physiological data obtained from 313 children in kindergarten, 1st, and 2nd grade we examined whether within-person autonomic coordination during an emotion-inducing film task in kindergarten was associated with developmental change in resting autonomic activity. On average, these kindergarteners exhibited reciprocal coordination during the approach-oriented emotion (angry, happy) condition and a lack of coordination during the avoidance-oriented emotion (fear, sad) condition. Alignment with these patterns was associated with more typical autonomic development, specifically an increase in resting respiratory sinus arrhythmia (RSA) and a decrease in resting skin conductance (SCR) from kindergarten to 2nd grade; while lack of coordination during the approach condition was associated with a relatively delayed increase in resting RSA and a steeper decline in SCR, and reciprocal coordination during the avoidance condition was associated with a lack of RSA increase. Findings highlight the need for additional consideration of how moment-to-moment dynamics of autonomic coordination influence longer-term development, and suggest that early patterns of atypical arousal may portend dysregulation of developing physiological systems.

Taking a few deep breaths significantly reduces children's physiological arousal in everyday settings: Results of a preregistered video intervention

This preregistered, randomized field experiment tested the effectiveness of a brief deep breathing intervention on children's concurrent physiological arousal in naturalistic settings (N  = 342; M_age  = 7.48 years; 46% female; 53% Asian, 26% White; 21% other race/ethnicity). The treatment consisted of an animated video that introduced deep breathing as a self-regulation strategy and scaffolded the child in taking a few slow-paced breaths, while the control group watched an informational video featuring similar animated images. Respiratory sinus arrhythmia (RSA) and heart rate (HR) were measured while children were sitting still (baseline) and subsequently while watching 1-min videos. Relative to baseline arousal, RSA increased and HR decreased only in response to the deep-breathing treatment video. Effects were larger in the second 30-s epoch of the video, which included most of the deep breathing practice. RSA fully mediated the intervention's effects on HR. By analyzing all children exposed to intervention video regardless of their engagement in the deep breathing practice (intention-to-treat design) and by using easily scalable treatment videos, the study identifies an effective and pragmatic approach to reducing children's physiological arousal in everyday, group settings. Implications for advancing applied developmental psychophysiological research are discussed.

Impact of stress and parenting on respiratory sinus arrythmia trajectories in early adolescence

The effects of stress and parenting on 1-year trajectories of physiological emotion regulation capacity among adolescents were examined. Consistent with the vulnerability-stress and allostatic load models, stress (chronic family and marital) was hypothesized to be associated with less favorable trajectories of basal respiratory sinus arrhythmia (RSA) over 1 year. This relationship was further hypothesized to be moderated by parenting practices (warmth, neglect, and rejection) and adolescent sex. Participants included 150 adolescents (51.3% female), 11-15 years of age (M = 13.04, SD = 0.89). Basal RSA and stress were assessed four times across 1 year. Results indicated a significant decrease in RSA over the course of 1 year (β = -0.15, p = .010). Warm parenting style was associated with lower RSA in environments of low marital stress and was also related with higher RSA in environments of high marital stress (β = 0.86, p = .021). Rejecting parenting styles were associated with higher RSA in environments of low family stress and lower RSA in environments of high family stress (β = -0.60, p = .014). These findings may be explained by the Yerkes-Dodson law of optimal stress, suggesting that sufficient environmental challenge is needed to catalyze regulatory development.

Linking autonomic nervous system reactivity with sleep in adolescence: Sex as a moderator

The purpose of the present study was to investigate relations between autonomic nervous system (ANS) reactivity across the parasympathetic and sympathetic branches and multiple sleep parameters in adolescence. Participants were 244 adolescents (Mage  = 15.79 years old, SD = 9.56 months; 67.2% White/European-American, 32.8% Black/African-American). Parasympathetic activity was indexed by respiratory sinus arrhythmia (RSA) withdrawal and sympathetic activity was indexed by skin conductance level reactivity (SCL-r), which were examined in response to a laboratory-based stressor (star-tracing task). Sleep was assessed with actigraphs in adolescents' homes for seven consecutive nights. Two sleep parameters were examined: sleep duration indexed by actual sleep minutes and sleep quality indexed by sleep efficiency from sleep onset to wake time. Regression analyses showed that more RSA withdrawal (lower RSA during task than baseline) was associated with shorter sleep, and more SCL-r (higher SCL during task than baseline) was associated with poorer sleep efficiency. Moderation analyses showed that associations linking RSA withdrawal with fewer sleep minutes and poorer sleep efficiency, and SCL-r with fewer sleep minutes were significant only for boys. Results illustrate that higher daytime physiological reactivity (increased RSA withdrawal and SCL-r) is negatively associated with sleep duration and efficiency for adolescents, especially boys.

Interpretation biases and depressive symptoms among anxiety-disordered children: The role of individual differences in respiratory sinus arrhythmia

Individual differences in interpretation biases-the tendency to interpret ambiguous stimuli as threatening-partially explain the presence of comorbid depressive symptoms among anxious youth. Increasing efforts have examined physiological processes that influence the association between interpretation biases and depressive symptoms in this population, and potential gender differences in this relationship. This study examined the moderating role of respiratory sinus arrhythmia (RSA) suppression (i.e., decrease from baseline)-an index of parasympathetic nervous system reactivity-in the association between interpretation biases and depressive symptoms in clinically anxious youth. One-hundred-and-five clinically anxious children (Mage  = 10.09 years, SD = 1.22; 56.7% female; 61.9% racial/ethnic minority) completed measures of self-reported and behaviorally indexed interpretation biases, reported anxiety/depression symptom severity, and participated in a speech task. RSA suppression during the task moderated the association between interpretation biases and depressive symptom severity in the total sample. Separate exploratory moderation analyses were conducted among girls and boys. Among girls, RSA suppression moderated the association between behaviorally indexed interpretation biases and depressive symptoms, and marginally moderated (p = .067) the association between self-reported interpretation biases and depressive symptoms. Among boys, RSA suppression was not a significant moderator. These findings may help identify clinically anxious youth most at-risk for comorbid depressive symptoms.

The longitudinal negative impact of early stressful events on emotional and physical well-being: The buffering role of cardiac vagal development

Early stressful events negatively affect emotional and physical well-being. Cardiac vagal tone (CVT), which is associated with better emotional and physical well-being, usually gradually increase in early childhood. Nonetheless, children's CVT developmental trajectories are greatly variable, such that CVT can increase or decrease across the years. The present study examines the longitudinal effects of early stressful events and the role of 4 years CVT developmental trajectory on children's emotional and physical well-being. Forty-two 4-year-old children were enrolled. Number of stressful events and resting electrocardiogram (ECG) were collected at T1. ECG was registered again after one (T2), two (T3) and three (T4) years. Children's emotional and physical well-being were assessed at T4 through the Child Health and Illness Profile - Child Edition (CHIP-CE). CVT development was calculated as the angular coefficient, reflecting the developmental trajectory of CVT across the four timepoints. Results yielded that higher experienced stressful events predicted poorer emotional and physical well-being after 4 years. The interaction between the number of stressful events and CVT development emerged on physical well-being. Early stressful events negatively affect long-term children's emotional and physical well-being while a positive CVT development seems to mitigate the negative effects of early stressful events on physical well-being.

Moderation of associations between interparental stress and (mal)adaptation by adolescents' personality: Contrasting differential susceptibility and diathesis-stress models

Objective

This study aimed to contrast differential susceptibility and diathesis–stress models in examining adolescents' Big Five personality dimensions as moderators of longitudinal associations between interparental stress and (mal)adaptation in emerging adulthood (i.e., self‐efficacy, externalizing and internalizing behavior).

Method

Data from the large longitudinal Flemish Study on Parenting, Personality and Development were used (475 families, adolescents' M_age = 15.82, SD_age = 1.15), with both parents reporting on their interparental stress and mothers reporting on the adolescent's personality and in 2009, and emerging adults reporting on their own (mal)adaptive functioning in 2009 and 2015 and their personality in 2015.

Results

Multivariate models showed that extraversion, benevolence, emotional stability and imagination were uniquely related to (mal)adaptation across the 6‐year interval. In general, our results exhibited no consistent moderating role for adolescents' personality. Only for girls, high levels of extraversion functioned as a “susceptibility maker” in associations between father's interparental stress and self‐efficacy, and, low levels of emotional stability functioned as a “vulnerability marker” in associations between parents' interparental stress and self‐efficacy.

Conclusions

The interaction effects as well as their (restricted) generalizability across gender should be replicated before drawing firm conclusions. Adolescents' personality characteristics were important predictors of (mal)adaptation during the transition into emerging adulthood.

A latent change score approach to understanding dynamic autonomic coordination

Children's self-regulation is a core adaptive system in child development. Physiological indices of regulation, particularly the autonomic nervous system (ANS), have garnered increased attention as an informative level of analysis in regulation research. Cardiography supports the simultaneous examination of both ANS branches via measures of pre-ejection period (PEP) and respiratory sinus arrhythmia (RSA) as indicators of sympathetic and parasympathetic activity, respectively. However, despite their heavily intertwined functions, research examining autonomic coordination across sympathetic and parasympathetic systems is scarce. Moreover, extant efforts have favored static, mean level reactivity analyses, despite the dynamic nature of ANS regulation and the availability of analytic tools that can model these processes across time. This study drew on a sample of 198 six-year-old children from a diverse community sample (49.5% female, 43.9% Latinx) to examine dynamic autonomic coordination using bivariate latent change score modeling to evaluate bidirectional influences of sympathetic and parasympathetic activity over the course of a challenging puzzle completion task. Results indicated that children evidenced reciprocal sympathetic activation (i.e., PEP attenuation and RSA withdrawal) across the challenge task, and these regulatory responses were characterized by a temporally leading influence of PEP on lagging changes in RSA. The current findings contribute to our understanding of children's autonomic coordination while illustrating a novel analytic technique to advance ongoing efforts to understand the etiology and developmental significance of children's physiological self-regulation.

Cortical and affective regulation of autonomic coordination

Although anatomical research clearly demonstrates the ability of the sympathetic and parasympathetic branches of the autonomic nervous system to independently influence cardiac function, little research has examined whether coordinated activation is typical or whether the extent of autonomic coordination is situationally dependent. This study examines the extent of coordination between sympathetic (cardiac pre-ejection period: PEP) and parasympathetic (respiratory sinus arrhythmia: RSA) influences on the cardiac function to determine whether coordination is a trait-like between-person characteristic or a state-varying within-person phenomenon, and if so, whether variability in autonomic coordination is modulated by cognitive (P3b amplitude) or affective state. Kindergarten-aged children (n = 257) completed a go/no-go task administered in blocks designed to induce affective states through the delivery of reward (Blocks 1 and 3) and frustration (Block 2). Results from multilevel models that allowed for the simultaneous examination of between-person and within-person associations in the repeated measures data suggested that (a) children with higher overall RSA also tended to have higher overall PEP; (b) at within-person level, RSA and PEP tended to be reciprocally coordinated; but that (c) when frustration invokes cognitive disengagement, coordination between parasympathetic and sympathetic systems demonstrate compensatory coordination. These findings highlight the extent to which the coordination of autonomic systems is a dynamic state-like phenomenon rather than a trait-like individual differences characteristic.

Childhood anxiety sensitivity, fear downregulation, and anxious behaviors: Vagal suppression as a moderator of risk

Anxiety sensitivity-the fear that anxiety-related sensations will result in catastrophic physical, social, or psychological consequences-is a robust risk factor for clinical anxiety. However, less is known about how anxiety sensitivity may interact with physiological modulation of arousal to predict anxious children's fear responses. The present investigation examined vagal withdrawal as a moderator of the association between anxiety sensitivity and anxious children's ability to downregulate subjective feelings of fear in response to an anxiety-provoking speech task. Observer ratings of anxious behaviors and performance during the task were also examined. It was hypothesized that children's anxiety sensitivity levels would interact with respiratory sinus arrhythmia (RSA) suppression to explain unique variance in subjective fear downregulation, anxious behaviors, and task performance. Participants were 105 children with anxiety disorders (N = 105; M = 10.07 years, SD = 1.22; 57% female) who completed diagnostic interviews, questionnaires, a speech about their family, and an RSA assessment in baseline and speech conditions. Interactions between RSA suppression and anxiety sensitivity predicted unique variance in subjective fear downregulation. Specifically, the greatest difficulties downregulating subjective fear responses were exhibited by children with high anxiety sensitivity and low RSA suppression. Interactions between RSA suppression and anxiety sensitivity did not predict variance in observer ratings of anxious behaviors or task performance. However, higher baseline RSA and speech RSA were significantly associated with fewer anxious behaviors during the speech. Higher baseline RSA was also significantly associated with better speech performance. These findings highlight the importance of vagal withdrawal and its interaction with anxiety sensitivity in predicting downregulation of subjective fear among clinically anxious children.

Temperamental vulnerability to emotion dysregulation and risk for mental and physical health challenges

Emotion dysregulation characterizes many forms of psychopathology. Patterns of dysregulation occur as a function of a developmental process in which normative and adaptive emotion regulation skills fail to become part of the child's behavioral repertoire due to biological, psychological, and contextual processes and experiences. Here we highlight the processes involved in the dysregulation of temperamental anger and frustration that become core features of externalizing problems and place children at risk for more serious forms of psychopathology. We imbed these processes in a larger self-regulatory framework, and we discuss how they influence mental as well as physical health, using data from our 20-year longitudinal study following a large cohort of children into young adulthood. Recommendations are made for future research involving the integration of biological systems with mental and physical health outcomes.
