Exuberant and inhibited children: Person-centered profiles and links to social adjustment

Parent-Reported Toddler Dysregulation and Respiratory Sinus Arrhythmia Predict Trajectories of Childhood Externalizing Behaviors

Externalizing behaviors (e.g., aggression, oppositionality, conduct problems) typically peak then decrease across early childhood (ages 2-5). However, some children continue to exhibit elevated levels of externalizing behavior throughout childhood, which can have implications for later socioemotional difficulties. Emotion regulation (ER) is an early predictor of continuity in externalizing behaviors. Toddlers with poor ER are more likely to exhibit externalizing behaviors during childhood. Additionally, individual differences in resting autonomic nervous system activity (respiratory sinus arrhythmia; RSA) reflect the capacity for physiological regulation and therefore may moderate associations between early dysregulation and later externalizing behaviors. Therefore, the current study (n = 174) examined the interaction between 18-month toddler behavioral dysregulation and resting RSA in the prediction of externalizing behaviors across early childhood (ages 4-6). Toddlers high in behavioral dysregulation and with lower RSA showed increased levels of externalizing behaviors across early childhood. Toddlers with higher RSA showed decreasing levels of externalizing behaviors across early childhood. These results highlight the importance of using multimethod approaches that capture different dimensions of regulation when examining the role of regulation in externalizing behaviors as the capacity for early physiological regulation may interfere with behavioral regulation to influence the express of later problematic behavior.

Contribution of Temperament and Family Functioning on Psychological Well-Being in Spanish Emergent Adults: A Person-Centered Approach

There is a gap in the literature on relationships between temperament, family functioning, and psychological well-being from a eudamonic perspective in emerging adulthood. To shed light on this issue, the aim of our study was to analyze the effect of temperament and family functioning profiles on psychological well-being in a sample of Spanish university students (N = 332). Results showed a positive association between the resilient temperament profile and psychological well-being, while the inverse relationship was observed for the non-desirable temperament profile. The reserved profile was not significantly associated with psychological well-being. On the other hand, the healthy family functioning profile (with moderate and high scores in cohesion and moderate scores in flexibility) was linked to higher levels of well-being, unlike the unhealthy functioning profile (with low scores in cohesion and extreme scores in flexibility). Finally, the joint effect of temperament and family functioning points to a buffering or protective effect of family functioning profiles in relation to potentially "dangerous" or "beneficial" temperamental profiles in university students. Practical and clinical implications are discussed.

Developmental cascades from maternal preconception stress to child behavior problems: Testing multilevel preconception, prenatal, and postnatal influences

Although maternal stress during pregnancy and even before conception shapes offspring risk for mental health problems, relatively little is known about the mechanisms through which these associations operate. In theory, preconception and prenatal stress may affect offspring mental health by influencing child responses to postnatal caregiving. To address this knowledge gap, this study had two aims. First, we examined associations between preconception and prenatal stress with child temperament profiles at age four using multilevel assessment of maternal perceived stress and stress physiology. Second, we tested child temperament profiles as moderators of associations between observed parenting behaviors during a parent-child free-play interaction when children were 4 years old and child behavior problems 1 year later. Latent profile analyses yielded four distinct child temperament profiles: inhibited, exuberant, regulated low reactive, and regulated high reactive. Consistent with hypotheses, preconception, and prenatal stress each independently predicted the likelihood of children having temperament profiles characterized by higher negative emotionality and lower regulation. Specifically, preconception perceived stress and prenatal cortisol predicted likelihood of children having an exuberant temperament, whereas prenatal perceived stress predicted likelihood of children having an inhibited temperament. Contrary to hypotheses, temperament profiles did not moderate predictions of child behavior problems from observed parenting behaviors; however, responsive parenting behaviors inversely predicted child behavior problems independently of child temperament. These findings add to growing evidence regarding effects of preconception factors on child outcomes and underscore a central role for responsive parenting behaviors in predicting more favorable child mental health independent of child temperament.

Preschool Teachers' Cognitions, Emotions, and Tolerance toward Children's Hypothetical Social Behaviors in the Classroom

Teachers' tolerance toward children's social behaviors is, in part, guided by teachers' cognitions and emotions. Few studies have examined the associations between teachers' cognitions, emotions, and tolerance toward children's social behaviors. This study aimed to (1) describe the cognitions, emotions, and tolerance of Portuguese preschool teachers toward children's shy, physically and relationally aggressive, rough-and-tumble play, exuberant, and unsociable behaviors at preschool, depending on children's sex; and (2) examine the direct and indirect associations (via teachers' emotions) between teachers' cognitions and tolerance toward children's social behaviors, depending on children's sex. One hundred and seven preschool teachers completed the Child Behaviors Vignettes. Preschool teachers displayed more negative views toward children's physical and relational aggression, reported positive perspectives toward children's rough play and mixed attitudes toward children's exuberance, and differentiated shy from unsociable behaviors. Direct associations between teachers' cognitions and tolerance were found only for physical aggression. Teachers' anticipation of negative peer costs and academic performance appear to exert an indirect influence on teachers' tolerance toward physical aggression and unsociability, via increased levels of worry. These findings highlight the role of teachers' emotions for tolerance toward children's social behaviors and the need to enhance their self-awareness.

Longitudinal associations between specific types of emotional reactivity and psychological, physical health, and school adjustment

Using a multimethod, multiinformant longitudinal design, we examined associations between specific forms of positive and negative emotional reactivity at age 5, children's effortful control (EC), emotion regulation, and social skills at age 7, and adolescent functioning across psychological, academic, and physical health domains at ages 15/16 (N = 383). We examined how distinct components of childhood emotional reactivity directly and indirectly predict domain-specific forms of adolescent adjustment, thereby identifying developmental pathways between specific types of emotional reactivity and adjustment above and beyond the propensity to express other forms of emotional reactivity. Age 5 high-intensity positivity was associated with lower age 7 EC and more adolescent risk-taking; age 5 low-intensity positivity was associated with better age 7 EC and adolescent cardiovascular health, providing evidence for the heterogeneity of positive emotional reactivity. Indirect effects indicated that children's age 7 social skills partially explain several associations between age 5 fear and anger reactivity and adolescent adjustment. Moreover, age 5 anger reactivity, low-, and high-intensity positivity were associated with adolescent adjustment via age 7 EC. The findings from this interdisciplinary, long-term longitudinal study have significant implications for prevention and intervention work aiming to understand the role of emotional reactivity in the etiology of adjustment and psychopathology.

Preschoolers' temperament and social functioning in novel and routine contexts

Introduction

The centrality of social competence to children's short and long-term well-being has sparked interest in the factors that contribute to its development, including temperament, a set of biologically based dispositions. A large body of work documents two types of temperamental dispositions associated with young children's social functioning: reactivity and regulation. There is consensus about the detrimental effects of negative reactive tendencies, called negative affective reactivity (NA), and about the beneficial effects of regulatory tendencies, called effortful control (EC), on social functioning. Another reactive component of temperament, Extraversion/Surgency (E/S) is less consistent in its relation with social functioning. Although NA is exacerbated by lack of familiarity, its contribution to social functioning in novel and routine contexts has not been systematically addressed.

Methods

To test this study's hypotheses, we devised a structured interview of adaptive responsiveness in context (ARC) which was completed by parents of preschoolers along with a comprehensive temperament questionnaire. Additionally, children completed an individually administered task measuring emotion-situation knowledge (N = 92) and their teachers completed a standard social competence questionnaire.

Results and Discussion

A path analysis that controlled for variance shared across contexts and temperamental traits showed that NA was the only unique predictor of social functioning in the Novel context, that EC was the only unique predictor of social functioning in the Routine context and that E/S was not a unique predictor of social functioning in either context. Bivariate analyses, conducted without controlling for context overlap, showed all reactive emotional traits (subsumed within NA and E/S) to correlate exclusively with ARC in the Novel contexts. However, regulatory traits showed a mixed pattern. Inhibitory Control correlated with ARC in both contexts but more highly in the Routine context, and Perceptual Sensitivity correlated with ARC in the Novel context.

Understanding How Child Temperament, Negative Parenting, and Dyadic Parent-Child Behavioral Variability Interact to Influence Externalizing Problems

To better understand the development of externalizing behavior, the current study examines how multiple levels of influence (child temperament, negative parenting, and dyadic interactions) work together to increase externalizing behaviors over time. Negative parenting (NP) and observed dynamic dyadic behavioral variability (DBV) in parent-child interactions (e.g., in discipline and compliance) are characteristic of coercive family processes. The present study first examined latent profiles of temperament in 3-year-olds (N = 150). Four temperament profiles emerged: high reactive, exuberant, low reactive, and inhibited. Temperament profiles were then examined as moderators of the effects of age 3 NP and DBV on child externalizing problems at age 4. Exuberant temperament exacerbated the association between higher levels of NP and DBV and higher levels of child externalizing. Additionally, temperament moderated the combined effects of NP and DBV such that at low and mean levels of NP, children with exuberant temperaments who experienced higher DBV had higher externalizing behaviors, whereas at higher levels of NP, the influence of DBV was no longer significant. Results suggest pathways by which children's experiences of NP and DBV with parents contribute to their greater externalizing problems over time, in the context of the child's unique temperament profile.

Mutual synergies between reactive and active inhibitory systems of temperament in the development of children's disruptive behavior: Two longitudinal studies

Individual differences in two inhibitory temperament systems have been implicated as key in the development of early disruptive behaviors. The reactive inhibition system, behavioral inhibition (BI) entails fearfulness, shyness, timidity, and caution. The active inhibition system, or effortful control (EC) entails a capacity to deliberately suppress, modify, or regulate a predominant behavior. Lower scores in each system have been associated with more disruptive behaviors. We examined how the two systems interact, and whether one can alleviate or exacerbate risks due to the other. In two community samples (Study 1, N = 112, ages 2.5 to 4, and Study 2, N = 102, ages 2 to 6.5), we assessed early BI and EC, and future disruptive behaviors (observed disregard for rules in Study 1 and parent-rated externalizing problems in Study 2). Robustly replicated interactions revealed that for children with low BI (relatively fearless), better EC was associated with less disruptive behavior; for children with low EC, more BI was associated with less disruptive behavior. This research extends the investigation of Temperament × Temperament interactions in developmental psychology and psychopathology, and it suggests that reactive and active inhibition systems may play mutually compensatory roles. Those effects emerged after age 2.

Convergent neural correlates of prenatal exposure to air pollution and behavioral phenotypes of risk for internalizing and externalizing problems: Potential biological and cognitive pathways

Humans are ubiquitously exposed to neurotoxicants in air pollution, causing increased risk for psychiatric outcomes. Effects of prenatal exposure to air pollution on early emerging behavioral phenotypes that increase risk of psychopathology remain understudied. We review animal models that represent analogues of human behavioral phenotypes that are risk markers for internalizing and externalizing problems (behavioral inhibition, behavioral exuberance, irritability), and identify commonalities among the neural mechanisms underlying these behavioral phenotypes and the neural targets of three types of air pollutants (polycyclic aromatic hydrocarbons, traffic-related air pollutants, fine particulate matter < 2.5 µm). We conclude that prenatal exposure to air pollutants increases risk for behavioral inhibition and irritability through distinct mechanisms, including altered dopaminergic signaling and hippocampal morphology, neuroinflammation, and decreased brain-derived neurotrophic factor expression. Future studies should investigate these effects in human longitudinal studies incorporating complex exposure measurement methods, neuroimaging, and behavioral characterization of temperament phenotypes and neurocognitive processing to facilitate efforts aimed at improving long-lasting developmental benefits for children, particularly those living in areas with high levels of exposure.

Toddler Exuberance as an Influence on Positive Social Behavior in a High-Intensity Context in Middle Childhood

Exuberance, a profile of temperament characterized in toddlerhood by high approach motivation, positive affect, and sociability, is associated with both adaptive and maladaptive socioemotional outcomes. The aims of the current study were to introduce a novel approach/avoidance-eliciting social task, as well as longitudinally extend our understanding of toddlerhood exuberance to outcomes in middle childhood. Specifically, affect and social behavior at age seven during a high-intensity game were compared to that observed during a low-intensity freeplay task. As part of a longitudinal study, 291 infants were selected at 4 months for a wide range of reactivity to novelty. The sample was assessed repeatedly across early childhood (9, 24, and 36 months of age) and at 7 years of age. A high exuberance profile was formed with approach, positive, and sociable behaviors observed in the laboratory from 4 to 36 months. At 7 years of age, affect and social behavior were assessed during high- and low-intensity interactions with an unfamiliar peer in the laboratory. Path Analyses using structural equation models demonstrated that a high exuberance profile was associated with greater positive social behavior at age 7 during a high-intensity game, but not negative social behavior or behavior during a low-intensity freeplay task. These results illuminate the need for targeted methodology, such as high-intensity approach/avoidance-eliciting social tasks, in order to clarify the links between early temperament and adaptive or maladaptive socioemotional outcomes across development.

A person-centered approach to understanding child temperament at ages 3 and 6

Person-centered analyses, such as latent profile analysis, provide an approach to assessing individual differences in child temperament that aligns with typological theory and is well positioned for translation to applied settings. In a community sample, latent profile analysis was conducted using seven temperament traits assessed through laboratory observation when children were three- and six-years-old. At age 3, a four-class model fit best and subgroups were labeled “typical,” “sluggish,” “surgent,” and “dysregulated,” based on the pattern of class-specific means. A five-class model fit best at age 6 and subgroups were labeled “typical,” “sluggish,” “outgoing,” “active-impulsive” and “negative affect.” Associations between class membership and mother-reported temperament traits, concurrently assessed, were mostly consistent with the class identities. Comparison of subgroup membership across waves generally demonstrated patterns of continuity across groups characterized by similar trait patterns. This paper provides an illustrative guide for temperament researchers in the implementation of latent profile analysis, addressing important methodical considerations. Increased utilization of person-centered approaches like latent profile analysis could lead to important advances in the study of child temperament, such as improved understanding of the continuity of temperamental styles and more targeted risk assessment.

The Influence of Early Childhood Temperament on Later Social-Emotional Functioning in Youth with Cancer

OBJECTIVE

One of the peak incidences of childhood cancer is during the early childhood years. This is also an important time for psychosocial and personality development, and it is well known that early childhood temperament influences later psychosocial functioning. However, this association has not been examined in young children with cancer.

METHODS

Parents of children with cancer (N = 39) and healthy comparisons (N = 35) completed an indicator of temperament (Children's Behavior Questionnaire) when children were young (Mage=4.99 ± 1.05 years). Five years later, parents and youth completed measures of psychosocial functioning (Mage=10.15 ± 1.10 years; Behavior Assessment Scale for Children, 2nd edition and Social Emotional Assets and Resilience Scale).

RESULTS

Parents of healthy comparisons reported that their children demonstrated greater surgency than youth with cancer; there were no differences in negative affect or effortful control. Children with cancer and healthy comparisons were rated similarly on measures of psychosocial functioning. Health status was not a significant predictor of later functioning, but socioeconomic status and temperament were. The influence of temperament was stronger for strengths-based functioning (e.g., social competence, adaptive functioning) versus distress (internalizing and externalizing problems).

CONCLUSIONS

Early childhood temperament is a strong predictor of later psychosocial functioning, regardless of health status. Findings highlight the need to consider temperament in the clinical assessment of psychosocial functioning in children with cancer. Additional research is needed to specifically assess how a diagnosis of cancer in early childhood influences temperament over time.

Differences in mother-child and father-child RSA synchrony: Moderation by child self-regulation and dyadic affect

Parents and preschoolers show respiratory sinus arrhythmia (RSA) synchrony, but it is unclear how child self-regulation and the dyadic affective climate shape RSA synchrony and how synchrony differs for mothers and fathers. We examined child average RSA, externalizing problems, and dyadic positive affect as moderators of the synchrony of dynamic, within-epoch child and parent RSA reactivity during a challenging task. Mothers (N = 82) and fathers (N = 60) oversampled for familial risk participated with their 3-year-olds. For mothers, when children showed either higher externalizing or lower average RSA, negative RSA synchrony was observed as dynamic coupling of maternal RSA augmentation and child RSA withdrawal, suggesting inadequate support of the child during challenge. However, when children showed both higher externalizing and lower average RSA, indicating greater regulatory difficulties overall, positive synchrony was observed as joint RSA withdrawal. The same patterns were found for father-child RSA synchrony but instead with respect to the moderators of higher externalizing and lower dyadic positive affect. Findings suggest moderators of RSA synchrony differ by parent and shared positive affect plays a robust role in fathers' RSA reactivity and synchrony. Mothers may be more attuned to children's regulatory capacities, whereas fathers may be more influenced by the immediate behavioral context.

Shyness and perceived monitoring by peers affect children's performance in a divided attention task

To engage effectively in a dynamic social world, children must be prepared to process incoming information quickly and efficiently. For some, the perception that one may be evaluated by peers may directly affect how they attend to and engage with the world around them. The current study examined how children's performance on a hierarchical figures task varies under perceived social and nonsocial conditions as a function of temperamental shyness. A total of 78 8-year-olds completed a self-report measure of shyness and two blocks of a divided attention task in which they identified targets appearing at the global or local level of a hierarchical figure. Children completed one block under standard laboratory conditions (Baseline condition) and completed the other block under the impression that their performance was being recorded and would be shown to other children of the same age (Social Monitoring condition). Results showed that children were faster and more accurate when targets appeared at the global level and when targets remained at the same level across trials. Furthermore, as shyness increased, children responded slower in the Social Monitoring condition relative to the Baseline condition. Notably, these changes in response time were not reflected by commensurate increases in accuracy. Potential processes and motivations underlying these differences in performance, as well as implications for children in real-world situations, are discussed.

Children's behavioral self-regulation and conscience: Roles of child temperament, parenting, and parenting context

This study examined longitudinal, temperament-specific relations between parenting qualities in two interactive contexts and behavioral measures of child self-regulation and conscience. Mother-toddler interactions were observed for maternal gentle control and mutual positivity and responsiveness (MPR) when children were 18 months old (sample N=134, 53% male, 92% non-Hispanic White). Child temperament was also assessed, yielding exuberant, inhibited, and average-approach temperament groups. Children's behavioral self-regulation and conscience were assessed at 4.5 years of age. Mother gentle control in a free play related to poorer later behavioral self-regulation for children in the average-approach group, whereas gentle control in a clean-up related to better behavioral self-regulation in the exuberant group. MPR during the clean-up related to better conscience in the inhibited group. These results provide further support for temperament- and context-specific relations between different parenting qualities and children's later regulatory skills, which may inform the development of more effective temperament-based parenting interventions.

Does Maternal Warmth Moderate Longitudinal Associations Between Infant Attention Control and Children's Inhibitory Control?

Attention control (AC) is thought to play an important role in the development of inhibitory control (IC) in children, yet there are few longitudinal studies of this association. This study used a prospective parent-child adoption design (N = 361 children) to examine whether maternal warmth at child age 27 months moderated the link between AC during infancy and IC during childhood. Tobit regression analyses indicated that low levels of infant AC at 9 months predicted low levels of IC at 6 years, controlling for birth parent IC, prenatal risk, infant distress to limitations, child sex, and openness of adoption. Adoptive mother warmth at 27 months moderated this association. In the context of higher levels of maternal warmth, the longitudinal association between low AC and low IC was attenuated. Thus, high levels of early maternal warmth may help diminish the effects of extant risk for IC deficits.

Effects of Gestational Age and Early Parenting on Children's Social Inhibition at 6 Years

Preterm birth (<37 weeks' gestation) has been associated with problems in social functioning. Whether social inhibition is specifically related to preterm birth and whether early parenting may protect against social inhibition difficulties is unknown. To explore effects of gestational age and early parent-infant relationships on social inhibition, 1314 children born at 26-41 weeks gestational age were studied as part of the prospective Bavarian Longitudinal Study. Early parent-infant relationship quality was assessed postnatally with the parent-infant relationship index. Social inhibition was assessed at age 6 years using an experimental procedure, in which nonverbal and verbal responses were coded into social inhibition categories (disinhibited, normally responsive, inhibited). Multinomial logistic regressions indicated that children with lower gestational age showed more socially disinhibited (nonverbal: OR = 1.27 [95% CI = 1.17-1.40], verbal: OR = 1.23 [95% CI 1.13-1.35]) and inhibited (nonverbal: OR = 1.21 [95% CI = 1.11-1.32], verbal: OR = 1.11 [95% CI = 1.01-1.21]) responses. Good early parent-infant relationships were associated with less verbal disinhibition (OR = 0.70 [95% CI = 0.52-0.93]). Findings suggest that children with lower gestational age are at greater risk to be both socially inhibited and disinhibited. Early parenting affected risk of abnormal social responses. Supporting early parent-infant relationships may reduce preterm children's risk for social difficulties.

Predicting child temperament and behavior from the fetus

There remains little debate that the period before birth sets the stage for subsequent development, yet scant evidence exists showing continuity from characteristics of the individual fetus to characteristics of the child. This report examines, in two studies, whether baseline and evoked fetal neurobehavioral functioning are predictive of features of child temperament and behavior as reported by mothers when offspring were between 7 and 14 years old (M = 10.1 years). Study 1 utilizes data generated from 333 maternal-fetal pairs collected during an undisturbed condition during the second half of gestation in relation to the child temperament dimensions of behavioral inhibition and exuberance. Associations at 32 weeks gestation were detected between all features of fetal neurobehavior and behavioral inhibition. In adjusted models, slower fetal heart rate and less fetal movement were associated with significant unique variance in predicting higher levels of childhood behavioral inhibition. No associations were detected for exuberance. Study 2 focuses on the association of evoked fetal reactivity and recovery to induced maternal arousal with subsequent child behavioral difficulties in a subset of the full sample (n = 130). Greater recovery in fetal heart rate following maternal stimulation was predictive of fewer behavioral difficulties and more prosocial behavior in childhood. Results from both studies provide support for gestational origins of core individual differences that portend childhood outcomes with foundational reactivity and regulatory components.

Maternal Responsiveness Protects Exuberant Toddlers from Experiencing Behavior Problems in Kindergarten

RESEARCH FINDINGS

Exuberant temperament, characterized by high approach and positive affect, is linked to socioemotional outcomes including risk for externalizing symptoms across development. Externalizing problems interfere with children's school readiness and lead to disruptive behavior in the classroom. While some moderating factors help identify which exuberant children are at risk and in which contexts they are at risk, few studies have identified early moderators that protect against maladjustment when children enter school. In the current study, we examined exuberant temperament in 124 toddlers and classroom behavior problems reported by kindergarten teachers. We also assessed the impact of maternal responsiveness at 24 months on the relation between exuberance and classroom behavior problems. As hypothesized, we found that higher exuberance predicted more behavior problems. Additionally, maternal responsiveness moderated this association such that high responsiveness protected exuberant children from classroom behavior problems.

PRACTICE OR POLICY

These results expand our understanding of socioemotional risks for exuberant children and how these risks influence school readiness. We also find that maternal responsiveness during toddlerhood mitigates these risks, and our findings suggest that interventions for exuberant children at risk for behavior problems or poor school readiness should target parental responsiveness when children are toddlers.

Does Temperament Underlie Infant Novel Food Responses?: Continuity of Approach-Withdrawal From 6 to 18 Months

This study investigated whether temperamental approach-withdrawal underlies infants' responses to novel foods. Data were drawn from a longitudinal study of mother-infant dyads (n = 136). Approach-withdrawal responses to novel foods and novel toys were coded when infants were 6 and 12 months of age. When infants were 18 months of age, approach-withdrawal behaviors, positive affect, and negative affect were used in a latent profile analysis to identify groups of toddlers who exhibited similar responses to novelty. As predicted, novel food and novel toy responses were concurrently associated at 12 months and followed a similar developmental pattern across the 1st year. Furthermore, novel food acceptance at 12 months of age, but not 6 months, predicted greater toddler approach.
