Grandmother-grandchild physiological synchrony in Chinese three-generation families: Links with child emotion regulation.

The current study examined the characteristics of physiological synchrony between grandmothers and grandchildren in Chinese three-generation families, and the associations between physiological synchrony and child emotion regulation. The participants included 92 children (age 8-10-year old) and their grandmothers. Respiratory sinus arrhythmia (RSA) was collected from both grandmothers and their grandchildren throughout a collaborative drawing task and a conflict discussion task. Child emotion regulation was measured using the Children's Emotional Management Scale. We found no evidence for an overall pattern of concordant or discordant synchrony within dyads. Instead, there was great variability in patterns of synchrony across dyads. During the collaborative drawing task, concordance in grandmother's RSA and grandchildren's subsequent RSA was linked with better emotion regulation. During the conflict discussion, concordance in grandmother's RSA and grandchildren's simultaneous RSA was linked with poorer emotion regulation. These results suggest that grandmother-grandchild synchrony in different directions, time lags, and contexts has different influences on children's emotion regulation. The findings of this study highlight the importance of contextual physiological co-regulation between Chinese children and their grandmothers for children's social-emotional development.

Emotion regulation as a predictor of patterns of change in behavior problems in previously institutionalized youth.

Longitudinal trajectories of psychopathology in previously institutionalized (PI) youth were identified and biobehavioral emotion regulation processes were examined as developmental mechanisms that predict these trajectories. Mental health data were collected from PI (N = 132) and nonadopted (NA; N = 175) youth across four time points (participant age ranged from 7- to 21-year-old). Using semiparametric group-based methods, the probability that each individual belonged to a distinct group that followed a specific pattern of behavior across time was estimated. We then tested whether unique aspects of emotion regulation (global, observed, and biological) were differentially associated with membership in externalizing and internalizing trajectory groups using multinomial logistic regression models. Four externalizing trajectories were identified for the PI and NA groups. For PI youth, global, observed, and biological emotion regulation processes were uniquely predictive of more adaptive externalizing trajectories. For NA youth, only parent-reported global emotion regulation was predictive of externalizing patterns. Three internalizing trajectories were identified for PI and NA youth. Generally, only parent-reported global emotion regulation predicted internalizing group membership for both PI and NA youth. Results suggest that biobehavioral emotion regulation processes may be particularly important predictors and potential points of intervention when targeting trajectories of externalizing behaviors in PI children.

Developmental antecedents of attention-deficit/hyperactivity disorder symptoms in middle childhood: The role of father-child interactions and children's emotional underregulation.

The present study examined the influence of fathers' parenting quality during infancy on children's emotion regulation during toddlerhood and, subsequently, attention-deficit/hyperactivity disorder (ADHD) symptoms in middle childhood. Fathers and their 8-month-old infants (N = 124) were followed over time to obtain home observations of parenting quality at 8 and 24 months, laboratory observations of children's emotion regulation at 24 months, and teacher reports of children's ADHD symptoms at 7 years. A path analysis revealed that fathers' emotional disengagement in infancy and minimizing responses to children's distress in toddlerhood forecast children's development of ADHD symptoms in middle childhood. Further, a significant indirect effect was found such that fathers' parenting at 8 and 24 months predicted subsequent development of ADHD symptoms at age 7 through toddlers' difficulty regulating emotion. Implications of this study for early intervention and directions for future research are discussed.

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.

Private Speech and the Development of Self-Regulation: The Importance of Temperamental Anger.

In this study (N=160), we observed children's private (i.e., self-directed) speech (PS) during a challenging puzzle task at age 3 and assessed whether the amount and maturity of their PS predicted their inhibitory control (IC) at age 4 and indirectly emotion regulation at age 9. Additionally, we examined whether the direct and indirect effects of PS were moderated by children's temperament. As expected, the maturity of children's PS was positively associated with IC and this association was stronger when children were reported as higher in anger reactivity by mothers (the interaction accounting for 11% of the explained variance). Children low in temperamental anger tend to have good IC and may not need to use PS. When children were at or above the mean on anger reactivity, PS maturity was indirectly associated with better emotion regulation at age 9 through an influence on IC at age 4 (index of moderated mediation =1.03 [.10, 3.60]). Findings suggest that PS is an important self-regulatory tool for 3-year-olds who typically experience and express anger.

Relations between frontal EEG maturation and inhibitory control in preschool in the prediction of children's early academic skills.

Maturation of the prefrontal cortex (PFC) across the first few years of life is thought to underlie the emergence of inhibitory control (IC) abilities, which may play an important role in children's early academic success. In this growth curve modeling study (N = 364), we assessed developmental change in children's resting-state electroencephalogram (EEG) activity (6-9 Hz 'alpha' power) from 10 months to 4 years and examined whether the initial levels or amount of change in frontal alpha power were associated with children's IC at age 4 and indirectly academic skills at age 6. Results indicated that greater increases in frontal alpha power across the study period were associated with better IC, and indirectly with better performance on Woodcock-Johnson tests of reading and math achievement at age 6. Similar associations between change in EEG and age 4 vocabulary were observed but did not mediate an association with academic skills. Similar analyses with posterior alpha power showed no associations with IC. Findings underscore the significance of frontal lobe maturation from infancy to early childhood for children's intellectual development.

Associations between stress reactivity and behavior problems for previously institutionalized youth across puberty.

Megan Gunnar's pubertal stress recalibration hypothesis was supported in a recent study of previously institutionalized (PI) youth such that increases in pubertal stage were associated with increases in cortisol stress reactivity. This work provides evidence that puberty may open up a window of recalibration for PI youth, resulting in a shift from a blunted to a more typical cortisol stress response. Using the same sample (N = 132), the current study aimed to elucidate whether increases in cortisol are associated with increases in adaptive functioning or whether they further underlie potential links to developmental psychopathology. Specifically, we examined the bidirectional associations between cortisol stress reactivity and both internalizing and externalizing symptoms across three timepoints during the pubertal period. Youth reported on their own internalizing symptoms and parents reported on youths' externalizing symptoms. Cortisol reactivity was assessed during the Trier social stress test. Analyses revealed no associations between cortisol reactivity and externalizing symptoms across puberty for PI youth. However, longitudinal bidirectional associations did emerge for internalizing symptoms such that increases in cortisol reactivity predicted increases in internalizing symptoms and increases in internalizing symptoms predicted increases in cortisol reactivity. Findings suggest that recalibrating to more normative levels of cortisol reactivity may not always be associated with adaptive outcomes for PI youth.

Cognitive-affective strategies and cortisol stress reactivity in children and adolescents: Normative development and effects of early life stress.

This study examined cognitive-affective strategies as predictors of hypothalamic-pituitary-adrenal (HPA) axis responses to a social-evaluative stressor in adolescence as compared to late childhood as a function of early life experiences. Participants included 159 children (9-10 years) and adolescents (15-16 years) divided into two groups based on early care experiences: non-adopted youth raised in their birth families (n = 81) and post-institutionalized youth internationally adopted from orphanage care (n = 78). Youth completed a version of the Trier Social Stress Test modified for use with children and reported on their trait emotion regulation and coping strategies. Children reported more use of suppression and disengagement than adolescents, while adolescents reported more engagement coping strategies. Non-adopted and post-institutionalized youth did not differ in reported strategies. Cognitive reappraisal predicted higher cortisol reactivity in non-adopted children and adolescents, and was not associated with reactivity in the post-institutionalized group. This study has implications for efforts aimed at promoting self-regulation and adaptive stress responses during the transition to adolescence for both typically developing children and children who experienced adverse early care.

Emotion regulation and cortisol reactivity during a social evaluative stressor: A study of post-institutionalized youth.

In the current study, we compared emotion regulation abilities between post-institutionalized (PI; N = 124) and never-institutionalized non-adopted (NA; N = 172) children and adolescents (7-15 years). We assessed cortisol reactivity and coded emotion regulation during the speech portion of Trier Social Stress Test (TSST-M). Parents reported on their children's social, academic, and behavioral adjustment. Results suggest that emotion regulation abilities increased with age, but this increase was greater for NA than PI youth. With regard to cortisol, piecewise growth modeling revealed that at higher levels of emotion regulation PI youth had greater baseline values (after a period of time allowing for acclimation to the laboratory) and had steeper recovery slopes than NA youth. There was also a main effect of emotion regulation on the reactivity slope suggesting that for both groups, as emotion regulation increased, the cortisol reactivity slope decreased. Finally, greater emotion regulation predicted fewer internalizing behavior problems for PI youth but not for NA youth.

Developmental Cascade and Transactional Associations Among Biological and Behavioral Indicators of Temperament and Maternal Behavior.

An empirical model of temperament that assessed transactional and cascade associations between respiratory sinus arrhythmia (RSA), negative affectivity, and the caregiving environment (i.e., maternal intrusiveness) across three time points during infancy (N = 388) was examined. Negative affectivity at 5 months was associated positively with maternal intrusiveness at 10 months, which in turn predicted increased negative affectivity at 24 months. RSA at 5 months was associated positively with negative affectivity at 10 months, which subsequently predicted greater RSA at 24 months. Finally, greater RSA at 5 months predicted greater negative affectivity at 10 months, which in turn predicted greater maternal intrusiveness at 24 months. Results are discussed from a biopsychosocial perspective of development.

Self-regulation as a predictor of patterns of change in externalizing behaviors from infancy to adolescence.

We examined associations between specific self-regulatory mechanisms and externalizing behavior patterns from ages 2 to 15 (N = 443). The relation between multiple self-regulatory indicators across multiple domains (i.e., physiological, attentional, emotional, and behavioral) at age 2 and at age 5 and group membership in four distinct externalizing trajectories was examined. By examining each of these self-regulatory processes in combination with one another, and therefore accounting for their shared variance, we aimed to better understand which specific self-regulatory skills were associated most strongly with externalizing behavioral patterns. Findings suggest that behavioral inhibitory control and emotion regulation are particularly important in distinguishing between children who show normative declines in externalizing behaviors across early childhood and those who demonstrate high levels through adolescence.

Cardiac vagal regulation in infancy predicts executive function and social competence in preschool: Indirect effects through language.

Parasympathetic nervous system functioning in infancy may serve a foundational role in the development of cognitive and socioemotional skills (Calkins, 2007). In this study (N = 297), we investigated the potential indirect effects of cardiac vagal regulation in infancy on children's executive functioning and social competence in preschool via expressive and receptive language in toddlerhood. Vagal regulation was assessed at 10 months during two attention conditions (social, nonsocial) via task-related changes in respiratory sinus arrhythmia (RSA). A path analysis revealed that decreased RSA from baseline in the nonsocial condition and increased RSA in the social condition were related to larger vocabularies in toddlerhood. Additionally, children's vocabulary sizes were positively related to their executive function and social competence in preschool. Indirect effects from vagal regulation in both contexts to both 4-year outcomes were significant, suggesting that early advances in language may represent a mechanism through which biological functioning in infancy impacts social and cognitive functioning in childhood.

Temperamental Anger and Positive Reactivity and the Development of Social Skills: Implications for Academic Competence during Preadolescence.

RESEARCH FINDINGS: This study examines whether the development of social skills during childhood serves as a mechanism through which temperamental anger and positive reactivity in toddlerhood influences children's academic competence during preadolescence (N = 406). Temperamental anger at age 2 was negatively associated with children's social skills at age 7; in turn, children's social skills at age 7 were negatively associated with teacher report of academic competence and child and teacher report of school problems at age 10. All three indirect effects were significant suggesting that children's social skills at age 7 is one mechanism through which temperamental anger at age 2 is associated with age 10 child- and teacher-reported school problems. Temperamental positive reactivity was not associated with children's social skills or academic competence. PRACTICE OR POLICY: Results provide support for early entry points to teach toddlers, especially those high in anger reactivity, the skills to engage in socially appropriate interactions with classmates and teachers, which may lessen subsequent academic challenges.

Neurophysiological correlates of attention behavior in early infancy: Implications for emotion regulation during early childhood.

Current theoretical conceptualizations of regulatory development suggest that attention processes and emotion regulation processes share common neurophysiological underpinnings and behavioral antecedents such that emotion regulation abilities may build on early attentional skills. To further elucidate this proposed relationship, we tested whether early neurophysiological processes measured during an attention task in infancy predicted in-task attention behavior and whether infants' attention behavior was subsequently associated with their ability to regulate emotion during early childhood (N=388). Results indicated that greater electroencephalogram (EEG) power change (from baseline to task) at medial frontal locations (F3 and F4) during an attention task at 10months of age was associated with concurrent observed behavioral attention. Specifically, greater change in EEG power at the right frontal location (F4) was associated with more attention and greater EEG power at the left frontal location (F3) was associated with less attention, indicating a potential right hemisphere specialization for attention processes already present during the first year of life. In addition, after controlling for 5-month attention behavior, increased behavioral attention at 10months was negatively associated with children's observed frustration to emotional challenge at 3years of age. Finally, the indirect effects from 10-month EEG power change at F3 and F4 to 3-year emotion regulation via infants' 10-month behavioral attention were significant, suggesting that infants' attention behavior is one mechanism through which early neurophysiological activity is related to emotion regulation abilities during childhood.

Neural plasticity and the development of attention: Intrinsic and extrinsic influences.

The development of attention has been strongly linked to the regulation of emotion and behavior and has therefore been of particular interest to researchers aiming to better understand precursors to behavioral maladjustment. In the current paper, we utilize a developmental psychopathology and neural plasticity framework to highlight the importance of both intrinsic (i.e., infant neural functioning) and extrinsic (i.e., caregiver behavior) factors for the development of attentional control across the first year. We begin by highlighting the importance of attention for children's emotion regulation abilities and mental health. We then review the development of attention behavior and underscore the importance of neural development and caregiver behavior for shaping attentional control. Finally, we posit that neural activation associated with the development of the executive attention network may be one mechanism through which maternal caregiving behavior influences the development of infants' attentional control and subsequent emotion regulation abilities known to be influential to childhood psychopathology.

Emotional reactivity, self-control and children's hostile attributions over middle childhood.

Hostile attribution bias, a child's tendency to interpret ambiguous social information as threatening or hostile, has been discussed as an important point in which social, emotional and cognitive information intersect. This study explores the natural changes that occur in children's hostile attributions across three grades during middle childhood and examines how emotional reactivity and self-control at third, fourth and fifth grade independently and interactively relate to these trajectories. Participants included 919 children whose mothers reported on their emotional reactivity, whose teachers reported on their self-control and who completed an attribution bias interview, all at grades 3, 4 and 5. Results revealed that among children with a greater tendency to make hostile attributions at third grade, lower self-control at third grade was associated with greater initial hostile attribution bias and less decline in biases over time. Additionally, greater emotional reactivity at fourth grade was associated with declines in these children's hostile attributions, but only when self-control was also higher at fourth grade.

African American parents' racial and emotion socialization profiles and young adults' emotional adaptation.

The current study aimed to identify parents' profiles of racial and emotion socialization practices, to determine if these profiles vary as a function of family income and young adult child gender, and to examine their links with young adults' emotional adaptation. Participants included 192 African American young adults (70% women) who ranged in age from 18 to 24 years (M = 19.44 years). Four maternal profiles emerged: cultural-supportive (high cultural socialization and supportive responses to children's negative emotions), moderate bias preparation (moderate preparation for bias, promotion of mistrust, and nonsupportive responses to negative emotions), high bias preparation (high preparation for bias, promotion of mistrust, and nonsupportive responses), and low engaged (low across racial and socialization constructs). Three paternal profiles emerged: multifaceted (moderate across racial and emotion socialization constructs), high bias preparation, and low engaged. Men were more likely to have mothers in the high bias preparation and to have fathers in the multifaceted or high bias preparation profiles. Individuals with higher income were more likely to have mothers in the cultural-supportive profile and to have fathers in the multifaceted profile. Young adults whose mothers fit the cultural-supportive profile or the moderate bias preparation profile had lower levels of depressive symptoms than young adults whose mothers fit the high bias preparation profile.

Early physiological regulation predicts the trajectory of externalizing behaviors across the preschool period.

Early assessments of children's physiological functioning are shown to predict subsequent developmental outcomes. However, individual changes that occur in the development of physiological systems may be associated with the pattern of change in behavior across time. Thus, we examined change in respiratory sinus arrhythmia (RSA), an index of physiological regulation, as a time-varying predictor in order to assess whether RSA change at ages 3, 4, and 5 uniquely influenced the trajectory of externalizing behaviors from age 3 to 5. Results indicated that only at age 3 was RSA change significantly associated with decreases in externalizing behaviors over time. RSA change scores at ages 4 and 5 were unrelated to trajectories of externalizing behavior, suggesting that the ability to physiologically regulate by age 3 may contribute to the development of skills that facilitate more control over behavior throughout preschool, and therefore may be more strongly associated with the pattern of change in externalizing behaviors than later physiological regulation.

The relation between maternal emotional support and child physiological regulation across the preschool years.

Trajectories of baseline RSA (respiratory sinus arrhythmia), an index of reactivity, and vagal withdrawal, an index of regulation, across the preschool period were examined. In addition, maternal emotional support was investigated as a potential time-varying predictor of these trajectories. Physiological measures were obtained during frustration tasks, and a maternal emotional support measure was assessed via maternal report and direct observation. Children's baseline RSA and vagal withdrawal scores were moderately stable across the preschool period. Growth models indicated that children's baseline RSA scores changed linearly over the preschool years, and there was significant variability in withdrawal trajectories. Greater maternal emotional support predicted higher initial withdrawal levels and lower emotional support was associated with the greatest increase in withdrawal over time. This suggests that children of higher emotionally supportive mothers reached higher levels of physiological regulation earlier in development and therefore did not show the same increase across preschool as children of less supportive mothers. Maternal emotional support was not significantly related to trajectories of baseline RSA.

Previously institutionalized toddlers' social and emotional competence and kindergarten adjustment: Indirect effects through executive function.

Longitudinal multimethod data across three time points were examined to explore the associations between previously institutionalized toddlers' (N = 71; 59% female) socioemotional skills (Time Point 1: 18 months to 3-years-old), executive functioning (i.e., attention, working memory, inhibitory control) in the preschool years (Time Point 2: 2-4-years-old), and adjustment in kindergarten (5-6-years-old). Children were from multiple regions (35% Eastern European, 31% Southeast Asian, 25% African, and 9% Latin American), and 90% of adoptive parents were White from the Midwestern United States. Socioemotional competency at Time Point 1 was associated with fewer attention problems and greater inhibitory control at Time Point 2, which were subsequently associated with more observed social competence, greater observed classroom competence, and less teacher-reported teacher-child conflict in kindergarten. Indirect effects from socioemotional competencies in toddlerhood to kindergarten adjustment via executive functioning during the preschool period emerged.
