Children with a history of behaviorally inhibited (BI) temperament face a heightened risk for anxiety disorders and often use control strategies that are less planful. Although these relations have been observed concurrently in early childhood, middle childhood, and adolescence, few studies leverage longitudinal data to examine long-term prospective relations between cognitive control and anxiety. Using longitudinal data from 149 adolescents (55% female; from predominantly White middle-class families), we assessed temperament in toddlerhood and cognitive control and anxiety at 4, 12, 15, and 18 years of age. At age 4, separate measures of task switching and inhibitory control were obtained via the Dimensional Change Card Sort and Stroop tasks, respectively. At 12, 15, and 18 years of age, planful control was assessed with the AX-Continuous Performance Test, and anxiety symptoms were assessed via self-report. Growth curve models revealed that children with greater inhibitory control at age 4, regardless of BI status, experienced a sharper increase in anxiety symptoms across adolescence. Children with heightened BI during early childhood displayed lower levels of planful control at age 12, but experienced a more rapid improvement in these skills across adolescence. Children with greater task switching ability at age 4 displayed higher levels of planful control at age 12, but experienced a smaller increase in these skills across adolescence. Finally, children's growth rate for anxiety was unrelated to their growth rate for planful control. These findings reveal that early-life temperament, cognitive control, and anxiety remain interconnected across development, from toddlerhood to at least late adolescence.

Behavioral inhibition (BI) is a temperamental style characterized by cautious and fearful behaviors in novel situations. The present multi-method, longitudinal study examined whether young children's observed and parent-reported BI in social versus non-social contexts predicts different long-term psychosocial outcomes. Participants (N = 279) were drawn from a longitudinal study of socioemotional development. BI in social contexts ("social BI") was measured via children's observed wariness toward unfamiliar adults and peers at 24 and 36 months and parents' reports of children's social fear/shyness at 24, 36, and 48 months. BI in non-social contexts ("non-social BI") was measured via children's observed fearful responses to masks and novel toys, and parents' reports of children's distress to non-social novelty at 9 months and non-social fear at 48 months. At 15 years, anxiety was assessed via adolescent- and parent-reports, and global internalizing and externalizing problems were assessed via parent-reports. Confirmatory factor analysis showed that a two-factor model fit the BI data significantly better than a single-factor model, providing evidence for the dissociation of BI in social versus non-social contexts. Social BI was uniquely associated with adolescent social anxiety, whereas non-social BI was specifically associated with adolescent separation anxiety. Neither social BI nor non-social BI predicted global internalizing and externalizing problems, providing evidence for the specific relations between BI and anxiety problems. Together, these results suggest that young children's inhibited responses in social versus non-social situations predict different subtypes of anxiety problems in adolescence, highlighting the multifaceted nature of BI and the divergent trajectories of different anxiety problems., (© 2023 The Authors.

Temperament involves stable behavioral and emotional tendencies that differ between individuals, which can be first observed in infancy or early childhood and relate to behavior in many contexts and over many years. 1 One of the most rigorously characterized temperament classifications relates to the tendency of individuals to avoid the unfamiliar and to withdraw from unfamiliar people, objects, and unexpected events. This temperament is referred to as behavioral inhibition or inhibited temperament (IT). 2 IT is a moderately heritable trait 1 that can be measured in multiple species. 3 In humans, levels of IT can be quantified from the first year of life through direct behavioral observations or reports by caregivers or teachers. Similar approaches as well as self-report questionnaires on current and/or retrospective levels of IT 1 can be used later in life., (Copyright © 2022 American Academy of Child and Adolescent Psychiatry.

Recent models of psychopathology suggest the presence of a general factor capturing the shared variance among all symptoms along with specific psychopathology factors (e.g., internalizing and externalizing). However, few studies have examined predictors that may serve as transdiagnostic risk factors for general psychopathology from early development. In the current study we examine, for the first time, whether observed and parent-reported infant temperament dimensions prospectively predict general psychopathology as well as specific psychopathology dimensions (e.g., internalizing and externalizing) across childhood. In a longitudinal cohort ( N = 291), temperament dimensions were assessed at 4 months of age. Psychopathology symptoms were assessed at 7, 9, and 12 years of age. A bifactor model was used to estimate general, internalizing, and externalizing psychopathology factors. Across behavioral observations and parent-reports, higher motor activity in infancy significantly predicted greater general psychopathology in mid to late childhood. Moreover, low positive affect was predictive of the internalizing-specific factor. Other temperament dimensions were not related with any of the psychopathology factors after accounting for the general psychopathology factor. The results of this study suggest that infant motor activity may act as an early indicator of transdiagnostic risk. Our findings inform the etiology of general psychopathology and have implications for the early identification for children at risk for psychopathology.

Introduction: Research suggests that certain parenting behaviors are best suited to promote optimal child development, depending on a child's distinctive temperamental presentation. This multimethod, longitudinal study examines the interactive effect of parenting and temperament in early childhood on the developmental trajectory of social anxiety in adolescence., Methods: Longitudinal growth modeling was used to examine the developmental trajectory of child social anxiety from age 9-15 and the interactive effect of parenting and child temperament at 36 months on the developmental trajectory of child social anxiety from age 9-15., Results: The slope of social anxiety from age 9-15 suggested a decrease in social anxiety throughout early adolescence. Furthermore, 36-month behavioral inhibition (BI) predicted the trajectory of child social anxiety from age 9-15 when parents displayed low and high levels of dismissive and supportive parenting (at 36 months)., Conclusions: Results support an interactive effect of infant temperament and parenting in early childhood (at 36 months) on the developmental trajectory of child social anxiety from age 9-15. Specifically, results suggest that engaging highly inhibited children with high supportive and low dismissive parenting may help reduce social anxiety over time in adolescence. Furthermore, parenting needs may differ for children high or low in BI to impact the developmental trajectory of social anxiety in adolescence, such that children who are high BI seem to benefit from low dismissive and high supportive parenting, and children who are low in BI seem to benefit more from high dismissive parenting., (© 2021 Wiley Periodicals LLC.)

Background: Children with the temperament of behavioral inhibition (BI) face increased risk for social anxiety. However, not all children with BI develop anxiety symptoms. Inhibitory control (IC) has been suggested as a moderator of the pathway between BI and social anxiety. This study uses longitudinal data to characterize development of IC and tests the hypothesis that IC moderates associations between early BI and later social anxiety symptoms., Methods: Children completed a Go/Nogo task at ages 5, 7, and 10 years as part of a longitudinal study of BI (measured at 2-3 years) and social anxiety symptoms (measured at 12 years). To assess IC development, response strategy (criterion) and inhibitory performance (d') were characterized using signal detection theory. Latent growth models were used to characterize the development of IC and examine relations among BI, IC parameters, and social anxiety symptoms., Results: IC response strategy did not change between 5 and 10 years of age, whereas IC performance improved over time. BI scores in toddlerhood predicted neither initial levels (intercept) nor changes (slope) in IC response strategy or IC performance. However, between ages 5 and 10, rate of change in IC performance, but not response strategy, moderated relations between BI and later parent-reported social anxiety symptoms. Specifically, greater age-related improvements in IC performance predicted higher levels of social anxiety in high BI children., Conclusions: IC development in childhood occurs independent of BI levels. However, rapid increases in IC performance moderate risk for social anxiety symptoms in children with BI. Implications for theory and practice are discussed., (© 2019 Association for Child and Adolescent Mental Health.)

Objective: Behavioral inhibition (BI) is a temperament identified in early childhood that is a risk factor for later social anxiety. However, mechanisms underlying the development of social anxiety remain unclear. To better understand the emergence of social anxiety, longitudinal studies investigating changes at behavioral neural levels are needed., Method: BI was assessed in the laboratory at 2 and 3 years of age (N = 268). Children returned at 12 years, and an electroencephalogram was recorded while children performed a flanker task under 2 conditions: once while believing they were being observed by peers and once while not being observed. This methodology isolated changes in error monitoring (error-related negativity) and behavior (post-error reaction time slowing) as a function of social context. At 12 years, current social anxiety symptoms and lifetime diagnoses of social anxiety were obtained., Results: Childhood BI prospectively predicted social-specific error-related negativity increases and social anxiety symptoms in adolescence; these symptoms directly related to clinical diagnoses. Serial mediation analysis showed that social error-related negativity changes explained relations between BI and social anxiety symptoms (n = 107) and diagnosis (n = 92), but only insofar as social context also led to increased post-error reaction time slowing (a measure of error preoccupation); this model was not significantly related to generalized anxiety., Conclusion: Results extend prior work on socially induced changes in error monitoring and error preoccupation. These measures could index a neurobehavioral mechanism linking BI to adolescent social anxiety symptoms and diagnosis. This mechanism could relate more strongly to social than to generalized anxiety in the peri-adolescent period., (Copyright © 2017 American Academy of Child and Adolescent Psychiatry.

This study tested the spectrum hypothesis, which posits that children and adolescents with high functioning autism (HFA) differ quantitatively but not qualitatively from typically developing peers on self-reported temperament. Temperament refers to early-appearing, relatively stable behavioral and emotional tendencies, which relate to maladaptive behaviors across clinical populations. Quantitatively, participants with HFA (N = 104, aged 10-16) self-reported less surgency and more negative affect but did not differ from comparison participants (N = 94, aged 10-16) on effortful control or affiliation. Qualitatively, groups demonstrated comparable reliability of self-reported temperament and associations between temperament and parent-reported behavior problems. These findings support the spectrum hypothesis, highlighting the utility of self-report temperament measures for understanding individual differences in comorbid behavior problems among children and adolescents with HFA.

Behavioral inhibition (BI) is a temperament associated with heightened vigilance and fear of novelty in early childhood, and social reticence and increased risk for anxiety problems later in development. However, not all behaviorally inhibited children develop signs of anxiety. One mechanism that might contribute to the variability in developmental trajectories is the recruitment of cognitive-control resources. The current study measured N2 activation, an ERP (event-related potential) associated with cognitive control, and modeled source-space activation (LORETA; Low Resolution Brain Electromagnetic Tomography) at 7 years of age while children performed a go/no-go task. Activation was estimated for the entire cortex and then exported for four regions of interest: ventromedial prefrontal cortex (VMPFC), ventrolateral prefrontal cortex (VLPFC), dorsal anterior cingulate cortex (dorsal ACC), and dorsal lateral prefrontal cortex (DLPFC). BI was measured in early childhood (ages 2 and 3 years). Anxiety problems and social reticence were measured at 7 years of age to ascertain stability of temperamental style. Results revealed that BI was associated with increased performance accuracy, longer reaction times, greater (more negative) N2 activation, and higher estimated dorsal ACC and DLPFC activation. Furthermore, early BI was only associated with social reticence at age 7 at higher (more negative) levels of N2 activation or higher estimated dorsal ACC or DLPFC activation. Results are discussed in the context of overcontrolled behavior contributing to social reticence and signs of anxiety in middle childhood., (© 2014 John Wiley & Sons Ltd.)

The present study utilized a multilevel approach to examine developmental trajectories in risk-taking propensity. We examined the moderating role of specific executive function components, attention shifting and inhibitory control, on the link between exuberant temperament in infancy and propensity for risk taking in childhood. Risk taking was assessed using a task previously associated with sensation seeking and antisocial behaviors. Two hundred ninety-one infants were brought into the lab and behaviors reflecting exuberance were observed at 4, 9, 24, and 36 months of age. Executive function was assessed at 48 months of age. Risk-taking propensity was measured when children were 60 months of age. The results indicated that exuberance and attention shifting, but not inhibitory control, significantly interacted to predict propensity for risk taking. Exuberance was positively associated with risk-taking propensity among children who were relatively low in attention shifting but unrelated for children high in attention shifting. These findings illustrated the multifinality of developmental outcomes for temperamentally exuberant young children and pointed to the distinct regulatory influences of different executive functions for children of differing temperaments. Attention shifting likely affords a child the ability to consider both positive and negative consequences and moderates the relation between early exuberance and risk-taking propensity.

Behaviorally inhibited children display a temperamental profile characterized by social withdrawal and anxious behaviors. Previous research, focused largely on adolescents, suggests that attention biases to threat may sustain high levels of behavioral inhibition (BI) over time, helping link early temperament to social outcomes. However, no prior studies examine the association between attention bias and BI before adolescence. The current study examined the interrelations among BI, attention biases to threat, and social withdrawal already manifest in early childhood. Children (N=187, 83 Male, M (age)=61.96 months) were characterized for BI in toddlerhood (24 & 36 months). At 5 years, they completed an attention bias task and concurrent social withdrawal was measured. As expected, BI in toddlerhood predicted high levels of social withdrawal in early childhood. However, this relation was moderated by attention bias. The BI-withdrawal association was only evident for children who displayed an attention bias toward threat. The data provide further support for models associating attention with socioemotional development and the later emergence of clinical anxiety.

The goals of the current study were to investigate the stability of temperamental exuberance across infancy and toddlerhood and to examine the associations between exuberance and social-emotional outcomes in early childhood. The sample consisted of 291 4-month-olds followed at 9, 24, and 36 months and again at 5 years of age. Behavioral measures of exuberance were collected at 9, 24, and 36 months. At 36 months, frontal electroencephalogram (EEG) asymmetry was assessed. At 5 years, maternal reports of temperament and behavior problems were collected, as were observational measures of social behavior during an interaction with an unfamiliar peer in the laboratory. Latent profile analysis revealed a high, stable exuberance profile that was associated with greater ratings of 5-year externalizing behavior and surgency, as well as observed disruptive behavior and social competence with unfamiliar peers. These associations were particularly true for children who displayed left frontal EEG asymmetry. Multiple factors supported an approach bias for exuberant temperament but did not differentiate between adaptive and maladaptive social-emotional outcomes at 5 years of age., ((c) 2011 APA, all rights reserved.)

One hundred thirty seven adolescents (M=15.3 yrs, SD=1.0 yr, n=72 girls) were recruited into temperament groups when they were 4 months of age based on reactivity to novel auditory/visual stimuli (Fox, Henderson, Rubin, Calkins, & Schmidt, 2001). Behavioral inhibition was observed across infancy (14 and 24 months). Additionally, self-reported substance-related problems and behavioral risk-taking was assessed during adolescence. High behavioral inhibition increased risk for substance-related problems among boys, whereas high behavioral inhibition protected against substance-related problems among girls, B=-1.18, SE=.48, 95% CI=-2.13 to -.24; p<.05. Additionally, high behavioral inhibition protected lower risk-taking children from adolescent substance-related problems whereas high behavioral inhibition increased risk for substance-related problems among higher risk-taking children, B=.04, SE=.02, 95% CI=.00 to .08. Findings from this prospective, multi-informant, longitudinal study suggest that risk-taking and gender may interact with temperamental traits to place adolescents at differential risk for substance-related related behavior problems., (Copyright © 2010 Elsevier Ltd.

Objective: Behavioral inhibition (BI), a temperamental style identifiable in early childhood, is considered a risk factor for the development of anxiety disorders, particularly social anxiety disorder (SAD). However, few studies examining this question have evaluated the stability of BI across multiple developmental time points and followed participants into adolescence-the developmental period during which risk for SAD onset is at its peak. The current study used a prospective longitudinal design to determine whether stable early BI predicted the presence of psychiatric disorders and continuous levels of social anxiety in adolescents. It was hypothesized that stable BI would predict the presence of adolescent psychiatric diagnoses, specifically SAD., Method: Participants included 126 adolescents aged 14 to 16 years who were first recruited at 4 months of age from hospital birth records. Temperament was measured at multiple time points between the ages of 14 months and 7 years. In adolescence, diagnostic interviews were conducted with parents and adolescents, and continuous measures of adolescent- and parent-reported social anxiety were collected., Results: Stable maternal-reported early BI was associated with 3.79 times increased odds of a lifetime SAD diagnosis, but not other diagnoses, during adolescence (95% confidence interval 1.18-12.12). Stable maternal-reported early BI also predicted independent adolescent and parent ratings of ongoing social anxiety symptoms., Conclusions: Findings suggesting that stable maternal-reported early BI predicts lifetime SAD have important implications for the early identification and prevention of SAD.

Objective: Behaviorally inhibited children face increased risk for anxiety disorders, although factors that predict which children develop a disorder remain poorly specified. The current study examines whether the startle reflex response may be used to differentiate between behaviorally inhibited adolescents with and without a history of anxiety., Method: Participants were assessed for behavioral inhibition during toddlerhood and early childhood. They returned to the laboratory as adolescents and completed a fear-potentiated startle paradigm and a clinical diagnostic interview (Schedule for Affective Disorders and Schizophrenia for School-Age Children-Present and Lifetime Version). Magnitude of the startle reflex was examined at baseline and during cues associated with safety and threat., Results: Only adolescents who showed high levels of behavioral inhibition and had a lifetime occurrence of anxiety disorders showed increased startle reactivity in the presence of safety cues. Neither behavioral inhibition nor diagnosis was related to startle reactivity during threat cues., Conclusions: These results suggest that neurobiological measures, such as the startle reflex, may be a potential risk marker for the development of anxiety disorders among behaviorally inhibited adolescents. These methods may enhance our ability to identify vulnerable individuals before the development of anxious psychopathology.

Variation in temperament is characteristic of all people but is rarely studied as a predictor of individual differences among individuals with autism. Relative to a matched comparison sample, adolescents with High-Functioning Autism (HFA) reported lower levels of Surgency and higher levels of Negative Affectivity. Variability in temperament predicted symptomotology, social skills, and social-emotional outcomes differently for individuals with HFA than for the comparison sample. This study is unique in that temperament was measured by self-report, while all outcome measures were reported by parents. The broader implications of this study suggest that by identifying individual variability in constructs, such as temperament, that may influence adaptive functioning, interventions may be developed to target these constructs and increase the likelihood that individuals with HFA will achieve more adaptive life outcomes.

Behavioral problems in young children can take on a variety of forms, which are linked to distinct antecedents and co-occurring markers. Internalizing difficulties in young children, for example, have been linked to individual differences in infant temperament and cortisol levels. In addition, there is growing evidence that these biobehavioral mechanisms are also shaped by gender. Four-year-old children participated in a study examining the relations between salivary cortisol and behavioral maladjustment as a function of gender and temperament. Both longitudinal (maternal report of infant temperament at 9 months) and concurrent (morning salivary cortisol at age 4) data were used to predict two forms of maladjustment: 'Withdrawal' (maternal report of internalizing behavior and laboratory observation of social reticence) and 'Acting Out' (maternal report of externalizing behavior and laboratory observation of solitary active play). High basal cortisol levels were strongly associated with Withdrawal in male participants. However, the relation was significant only in boys who exhibited high levels of negative temperament in infancy. There were no comparable findings with 'Acting Out' beyond a main effect of gender reflecting greater difficulty in boys. The data suggested that there are unique biobehavioral mechanisms shaping specific patterns of maladjustment in childhood.

Behavioral Inhibition is a temperament identified in the first years of life that enhances the risk for development of anxiety during late childhood and adolescence. Amongst children characterized with this temperament, only around 40 percent go on to develop anxiety disorders, meaning that more than half of these children do not. Over the past 20 years, research has documented within‐child and socio‐contextual factors that support differing developmental pathways. This review provides a historical perspective on the research documenting the origins of this temperament, its biological correlates, and the factors that enhance or mitigate risk for development of anxiety. We review as well, research findings from two longitudinal cohorts that have identified moderators of behavioral inhibition in understanding pathways to anxiety. Research on these moderators has led us to develop the Detection and Dual Control (DDC) framework to understand differing developmental trajectories among behaviorally inhibited children. In this review, we use this framework to explain why and how specific cognitive and socio‐contextual factors influence differential pathways to anxiety versus resilience.

Background: Social anxiety is amongst the most prevalent adolescent mental health problems; however, it is often unrecognized due to its comorbidity with other anxiety problems such as generalized anxiety. Thus, understanding the unique developmental pathways to social anxiety is critical for improving its prevention. We examined the pathway from maternal shyness, when children were 4 years old, to adolescents' social anxiety at age 15 through social wariness at age 7. We hypothesized that childhood social wariness would mediate the association between maternal shyness and social anxiety in adolescence. Methods: Participants (N = 291; 54% female) were followed from early childhood to adolescence. Mothers reported on their own shyness when children were 4 years old. Social wariness toward unfamiliar peers was observed in the laboratory at ages 4 and 7. Adolescent social anxiety and generalized anxiety were assessed via self‐report, parent‐report, and clinical diagnoses at age 15. Results: Maternal shyness was positively associated with adolescent social anxiety but not generalized anxiety at age 15. Higher levels of maternal shyness at age 4 predicted greater social wariness at age 7, which in turn predicted greater social anxiety but not generalized anxiety at age 15. Social wariness at age 7 partially mediated the association between maternal shyness and adolescent social anxiety. Conclusions: This study identifies a unique developmental pathway from maternal shyness to adolescent social anxiety. Findings suggest that childhood social wariness connects maternal shyness to adolescent social anxiety. [ABSTRACT FROM AUTHOR]

Individuals with a behaviorally inhibited (BI) temperament are more likely to develop social anxiety. However, the mechanisms by which socially anxious behavior emerges from BI are unclear. Variation in different forms of top‐down control, specifically executive functions (EF), may play distinct roles and characterize differential pathways to social anxiety. Here 291 children were assessed for BI in toddlerhood (ages 2 and 3), parent‐reported inhibitory control and set shifting during middle childhood (age 7), and multidimensional assessment of socially anxious behavior completed during late childhood and early adolescence (ages 9 and 12). Structural equation modeling revealed that early variation in BI predicted the development of socially anxious behavior through either higher levels of parent‐reported inhibitory control or lower levels of parent‐reported set shifting. These data reinforce the notion that top‐down control does not uniformly influence relations between temperament and socially anxious behavior. These data suggest novel approaches to thinking about the role of EFs and social anxiety outcomes as children approach adolescence. [ABSTRACT FROM AUTHOR]

The current study examined the interplay between children's dispositional anger and susceptibility to peers' influence in increasing children's risk‐taking behaviors. Participants in the current study were children from a larger study of temperament and social–emotional development who were followed across 9, 24, 36, 48, and 60 months. Dispositional anger was measured using mothers' reports across 9 and 48 months. At 60 months, children played a risk‐taking computer game in presence of an unfamiliar peer who watched the child play. The child's risk‐taking was assessed during the game as the unfamiliar peers' reactions were coded based on comments that were peer directed, reflective of praising the target child's performance, or object directed, indicative of excitement toward the game. A latent profile analysis revealed three longitudinal anger profiles across infancy to early childhood: high stable, average stable, and low stable anger. Results suggested that as peers' object‐directed comments predicted risk‐taking independent of children's anger, the association between peer‐directed comments and risk‐taking was dependent on children's dispositional anger. Specifically, when peers praised the target child's performance, children in the high stable anger profile showed increased risk‐taking propensity. Findings are discussed based on the importance of considering both temperamental characteristics and aspects of the peer context in relation to children's risk‐taking. [ABSTRACT FROM AUTHOR]

Behavioral inhibition (BI), a temperament characterized in early childhood by wariness and avoidance of novelty, is a risk factor for anxiety disorders. An enhanced startle response has been observed in adolescents characterized with BI in childhood, particularly when they also manifest concurrent symptoms of anxiety. However, no prior study has examined relations among BI, startle responsivity, and anxiety in a prospective manner. Data for the present study were from a longitudinal study of infant temperament. Maternal reports and observations of BI were assessed at ages 2 and 3. At age 7, participants completed a startle procedure, while electromyography was collected, where participants viewed different colors on a screen that were associated with either the delivery of an aversive stimulus (i.e., puff of air to the larynx; threat cue) or the absence of the aversive stimulus (i.e., safety cue). Parental reports of child anxiety were collected when children were 7 and 9 years of age. Results revealed that startle responses at age 7 moderated the relation between early BI and 9-year anxiety. These findings provide insight into one potential mechanism that may place behaviorally inhibited children at risk for anxiety. [ABSTRACT FROM AUTHOR]

Behavioral inhibition (BI) is an early-appearing temperament characterized by strong reactions to novelty. BI shows a good deal of stability over childhood and significantly increases the risk for later diagnosis of social anxiety disorder (SAD). Despite these general patterns, many children with high BI do not go on to develop clinical, or even subclinical, anxiety problems. Therefore, understanding the cognitive and neural bases of individual differences in developmental risk and resilience is of great importance. The present review is focused on the relation of BI to two types of information processing: automatic (novelty detection, attention biases to threat, and incentive processing) and controlled (attention shifting and inhibitory control). We propose three hypothetical models (Top-Down Model of Control; Risk Potentiation Model of Control; and Overgeneralized Control Model) linking these processes to variability in developmental outcomes for BI children. We argue that early BI is associated with an early bias to quickly and preferentially process information associated with motivationally salient cues. When this bias is strong and stable across development, the risk for SAD is increased. Later in development, children with a history of BI tend to display normative levels of performance on controlled attention tasks, but they demonstrate exaggerated neural responses in order to do so, which may further potentiate risk for anxiety-related problems. We conclude by discussing the reviewed studies with reference to the hypothetical models and make suggestions regarding future research and implications for treatment. [ABSTRACT FROM AUTHOR]

The current study examined the associations between the early childhood temperament of behavioral inhibition and children's displays of social problem-solving ( SPS) behavior during social exclusion. During toddlerhood (the ages of two to three), maternal report and behavioral observations of behavioral inhibition were collected. At the age of seven, children's SPS behaviors were observed during a laboratory social exclusion task based on the commonly used Cyberball game. Results showed that behavioral inhibition was positively associated with displayed social withdrawal and negatively associated with assertive behavior during the observed social exclusion task at seven years of age. These results add to our understanding of inhibited children's SPS behaviors during social exclusion and provide evidence for the associations between toddler temperament and children's social behavior during middle childhood. [ABSTRACT FROM AUTHOR]

The goals of the current study were to examine whether children's social problem solving (SPS) skills are a mechanism through which temperament influences later academic achievement and whether sex moderates these associations. The participants included 1117 children enrolled in the National Institute of Child Health and Human Development Study of Early Child Care. During preschool, mothers and childcare providers rated children's temperamental shyness and inhibitory control, and SPS was assessed using a hypothetical-reflective measure during a laboratory visit. During kindergarten and first grade, teacher-report of math and language skills was collected. The results indicated that high ratings of inhibitory control in preschool, but not shyness, predicted better kindergarten and first-grade academic skills. Furthermore, children's SPS competence mediated the relations between both shyness and inhibitory control on later academic skills. The child's sex did not moderate these associations. The results suggest that preventative efforts targeting early SPS skills may buffer against later academic adjustment problems among temperamentally extreme children. [ABSTRACT FROM AUTHOR]

Temperament works in combination with a child's environment to influence early socioemotional development. We examined whether maternal caregiving behavior at infant age 9 months moderated the relation between infant temperamental fear (9 months) and observations of children's social behavior with an unfamiliar peer at age 2 in a typically developing sample of 155 children. When infants received lower quality maternal caregiving, temperamental fear was inversely related to observed social engagement and aggression. These relations were nonsignificant when infants received higher quality maternal caregiving. Findings indicate that variations in temperamental fear may predict individual differences in future peer interactions, but sensitive, nonintrusive caregiving behaviors can attenuate these associations. [ABSTRACT FROM AUTHOR]

The present study examined the influence of children's experiences during non-maternal childcare on their behavior toward unfamiliar peers. Participants included children classified as negatively reactive at four months of age (N = 52) and children not negatively reactive (N = 61), who were further divided into those who experienced non-maternal care and those who did not. Children were observed during childcare at 24 months of age and in the laboratory with an unfamiliar peer at 24 and 36 months of age, where their wariness, dysregulation, and social engagement were assessed. Within the negatively reactive childcare group, children's positive interactions with peers during childcare at 24 months predicted lower levels of wariness toward an unfamiliar peer at 36 months. This relation was not significant for children not classified as negatively reactive. The findings suggest that the influence of non-maternal childcare is dependent on a child's temperament and on the nature of peer interactions during care. [ABSTRACT FROM AUTHOR]

The relations among infant anger reactivity, approach behavior, and frontal electroencephalogram (EEG) asymmetry, and their relations to inhibitory control and behavior problems in early childhood were examined within the context of a longitudinal study of temperament. Two hundred nine infants' anger expressions to arm restraint were observed at 4 months of age. Infants' approach behaviors during play with an unpredictable toy and baseline frontal EEG asymmetry were assessed at 9 months of age. Inhibitory control during a Go/No-Go task and parent report of behavior problems were evaluated at 4 years of age. High anger-prone infants with left, but not right, frontal EEG asymmetry showed significantly more approach behaviors and less inhibitory control relative to less anger-prone infants. Although a link between anger proneness in infancy and behavior problems in early childhood was not found, a combination of low approach behaviors and poor inhibitory control was predictive of internalizing behaviors.

Children with behavioral inhibition, a temperamental style characterized by infant distress to novelty and childhood social reticence, exhibit both continuity and discontinuity of this behavioral trait over the course of development. However, few researchers have identified factors that might be responsible for these different patterns. In the current study, childcare history, maternal personality, and maternal behavior were examined as moderators of the relations between infant temperament, preschool social reticence, and childhood social wariness. Seventy-seven children participated in this longitudinal study that began in infancy and continued into middle childhood. Maternal negative personality moderated the relation between infant temperament and childhood social wariness. In addition, maternal behavior moderated the relation between preschool social reticence and childhood social wariness. The findings suggest that a complex interplay of within-child and maternal factors affect the development of internalizing behavior in the early school years. [ABSTRACT FROM AUTHOR]

Abstract: In this paper we review current definitions and measurement approaches used to assess individual differences in children’s temperament. We review the neural bases of temperamental reactivity and self-regulation and propose that these constructs provide a framework for examining individual differences and developmental change in emotion–cognition interactions across development. Studies are reviewed in which some well-documented contextual effects on the expression of temperament can be interpreted in terms of the influence of biological and non-biological factors on CNS functioning. We conclude with ideas regarding future directions for the study of individual differences and developmental change in cognition–emotion interactions as they are shaped throughout development.

Behavioral inhibition refers to a temperament or style of reacting that some infants and young children exhibit when confronted with novel situations or unfamiliar adults or peers. Research on behavioral inhibition has examined the link between this set of behaviors to the neural systems involved in the experience and expression of fear. There are strong parallels between the physiology of behaviorally inhibited children and the activation of physiological systems associated with conditioned and unconditioned fear. Research has examined which caregiving behaviors support the frequency of behavioral inhibition across development, and work on the interface of cognitive processes and behavioral inhibition reveal both how certain cognitive processes moderate behavioral inhibition and how this temperament affects the development of cognition. This research has taken place within a context of the possibility that stable behavioral inhibition may be a risk factor for psychopathology, particularly anxiety disorders in older children. The current chapter reviews these areas of research and provides an integrative account of the broad impact of behavioral inhibition research. [ABSTRACT FROM AUTHOR]

• Children faster and more accurate at identifying global than local level targets. • Better performance when target remained at same level across subsequent trials. • As shyness increased, children slower in social relative to non-social condition. • However, shyness did not predict differences in accuracy between conditions. • Shyness relates to variable attentional task performance under social conditions. 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. [ABSTRACT FROM AUTHOR]

Objective: Behavioral inhibition (BI) is an infant temperament characterized by heightened reactivity and negative affect in response to novel people and situations. BI is among the earliest and strongest predictors of future anxiety problems. However, not all children with a history of BI will manifest anxiety problems. A growing body of evidence suggests that proactive control skills may help buffer youth with BI from future anxiety difficulties; yet, it remains unclear how temperament may interact with the development of cognitive control to influence anxiety risk. The present study tested whether enhancements in proactive control occurring during adolescence may reduce risk for anxiety among youth with a history of BI.Method: Participants included 185 adolescents (56% female) whose temperament was assessed during toddlerhood. In adolescence, participants completed anxiety assessments and an AX Continuous Performance Test (AX-CPT) to assess cognitive control strategy. Both assessments were administered at age 13 years and again at 15 years.Results: Latent change score modeling revealed that, on average, participants increasingly used proactive control strategies and experienced worsening anxiety from age 13-15 years. Early BI was associated with a smaller anxiety increase from 13-15 years, but only among participants whose proactive control skills improved at mean or greater rates.Conclusion: The present findings suggest that greater proactive control development during adolescence protects youth with high BI from age-related increases in anxiety. Results support a framework that highlights cognitive control as a key moderator of anxiety risk among children with a history of high BI. [ABSTRACT FROM AUTHOR]

Behavioral inhibition is a temperament assessed in the toddler period via children’s responses to novel contexts, objects, and unfamiliar adults. Social reticence is observed as onlooking, unoccupied behavior in the presence of unfamiliar peers and is linked to earlier behavioral inhibition. In the current study, we assessed behavioral inhibition in a sample of 262 children at ages 2 and 3, and then assessed social reticence in these same children as they interacted with an unfamiliar, same-age, same-sex peer at 2, 3, 4, and 5 years of age. As expected, early behavioral inhibition was related to social reticence at each age. However, multiple trajectories of social reticence were observed including High-Stable, High-Decreasing, and Low-Increasing, with the High-Stable and High-Decreasing trajectories associated with greater behavioral inhibition compared to the Low-Increasing trajectory. In addition, children in the High-Stable social reticence trajectory were rated higher than all others on 60-month Internalizing problems. Children in the Low-Increasing trajectory were rated higher on 60-month Externalizing problems than children in the High-Decreasing trajectory. These results illustrate the multiple developmental pathways for behaviorally inhibited toddlers and suggest patterns across early childhood associated with heightened risk for psychopathology.

Seven hundred seventy-nine infants were screened at 4 months of age for motor and emotional reactivity. At age 9 months, infants who showed extreme patterns of motor and negative (n = 75) or motor and positive (n = 73) reactivity and an unselected control group (n = 86) were administered the Laboratory Temperament Assessment Battery, and baseline electroencephalogram data were collected. Negatively reactive infants showed significantly more avoidance than positively reactive infants and displayed a pattern of right frontal electroencephalogram asymmetry. Positively reactive infants exhibited significantly more approach behavior than controls and exhibited a pattern of left frontal asymmetry. Results support the notion that approach-withdrawal bias underlies reactivity in infancy. [ABSTRACT FROM AUTHOR]

Abstract: The purpose of the current study is to describe the development and validation of a new measure of temperament, the Preschool Temperament Classification System (PTCS). The PTCS was developed as a typological measure that identifies children''s temperament styles as undercontrolled, resilient, or overcontrolled. The PTCS is a time efficient structured interview assessing children''s temperament as it is observed in the classroom environment. During the 20min interview, teachers classify all of the children in their class into one of the three temperament styles, rank order children within each temperament group, and assign an intensity rating to each child, indicating how well the child matches his/her assigned temperament group. Data were collected on 196 preschool-age children from 25 Head Start classrooms in an urban area. Teachers assessed children''s temperament and peer play behaviors, and trained research assistants assessed children''s school readiness. The PTCS classified children into temperament groups that showed expected relations to peer play competence and school readiness after controlling for age and gender, indicating good validity. Test–retest reliability was moderate to high. Overall the PTCS shows promise as a valid and reliable teacher measure of preschool children''s temperament. [Copyright &y& Elsevier]

Objective: The COVID-19 pandemic has brought unprecedented changes to young adults' lives, resulting in mental health difficulties for many; however, some individuals are particularly prone to heightened anxiety. Little is known about the early life predictors of anxiety during the pandemic. We examined a developmental pathway from behavioral inhibition (BI), a temperament characterized by fearful responses toward novelty, to changes in young adults' anxiety during the initial period of the pandemic. We hypothesized that a stable pattern of BI across early childhood would predict greater adolescent worry dysregulation, which in turn would predict increases in young adult anxiety during a stressful phase of the pandemic.Method: Participants (N = 291; 54% female) were followed from toddlerhood to young adulthood. BI was observed at ages 2 and 3 years. Social wariness was observed at age 7 years. Participants rated their worry dysregulation in adolescence (age 15) and anxiety in young adulthood (age 18) at 2 assessments during the COVID-19 pandemic, 1 month apart.Results: A significant moderated mediation, in which a stable pattern of BI from toddlerhood to childhood, as compared to the absence of this pattern, predicted greater worry dysregulation in adolescence. Worry dysregulation predicted elevated young adult anxiety in the second assessment during COVID-19, even after accounting for the first assessment.Conclusion: This study identifies a developmental pathway from toddlerhood BI to young adults' elevated anxiety during the COVID-19 pandemic. Findings have implications for early identification of individuals at risk for dysregulated worry and the prevention of anxiety during stressful life events in young adulthood.

We examined the longitudinal relation between behavioral inhibition (BI) and social anxiety symptoms and behavior and the mediating role of emotion regulation (ER). Moreover, we investigated the influence of parenting behavior on the development of ER strategies. Participants were 291 children (135 male) followed longitudinally from 2 to 13 years. Mothers were predominantly well educated and non-Hispanic Caucasian. Children were screened for BI using maternal report and observational measures (ages 2 and 3), parenting behavior was observed while children and their mothers participated in a fear-eliciting task (age 3), ER strategies were observed while children completed a disappointment task (age 5), and socially anxious behavior was measured via multimethod assessment at 10 and 13 years. Children who exhibited high BI in early childhood exhibited more socially anxious behavior across ages 10 and 13, and there was a significant indirect effect of BI on socially anxious behavior through ER strategies. Children who were high in BI demonstrated less engaged ER strategies during the disappointment task, which in turn predicted more socially anxious behavior. Furthermore, parenting behavior moderated the pathway linking early BI and ER strategies to social anxiety outcomes such that children who exhibited high BI and who received more affectionate/oversolicitous behavior from their mother displayed less engaged ER strategies and more socially anxious behavior than children low in BI or low in oversolicitous parenting behaviors. These findings expand on our understanding of the role that ER strategies and parenting play in the developmental pathway linking early BI to future social anxiety outcomes. [ABSTRACT FROM AUTHOR]

Behavioral inhibition (BI) is a temperament characterized in early childhood by distress to novelty and avoidance of unfamiliar people, and it is one of the best-known risk factors for the development of social anxiety. However, nearly 60% of children with BI do not go on to meet criteria for social anxiety disorder. In this review we present an approach to understanding differential developmental trajectories among children with BI. We review research using laboratory-based tasks that isolate specific attention processes that enhance versus mitigate risk for social anxiety among behaviorally inhibited children and studies that suggest that BI is associated with heightened detection of novelty or threat. Moreover, stimulus-driven control processes, which we term "automatic control," increase the probability that behaviorally inhibited children display socially reticent behavior and develop social anxiety. In contrast, goal-driven control processes, which we term "planful control," decrease risk for anxiety. We suggest that these three categories of processes (detection, automatic control, and planful control) function together to determine whether behaviorally inhibited children are able to flexibly regulate their initial reactions to novelty, and in turn, decrease risk for social anxiety. Although laboratory-based tasks have identified these processes underlying risk and resilience, the challenge is linking them to the emotions, thoughts, and behaviors of behaviorally inhibited children in real-world contexts.

Communicative abilities play a crucial role in children's social success and, for shyer children, protect against socio-emotional maladjustment. Despite communication being highly reciprocal, research on the dyadic influences of children's shyness on their own and their partner's communicative behaviours is limited. Addressing this gap, children (M age = 10.07 years; N = 338) were paired with a same-sex and same-age, unfamiliar peer and completed two puzzle tasks wherein one child ("instructor") could only see the puzzle, while the other child ("listener") could only move the pieces. Children's communicative behaviours were observed, with children switching roles between trials. Shyer instructors verbalized fewer instructions and received less encouragement from listeners during puzzle one. During puzzle two, shyer instructors verbalized fewer instructions and received more responses from listeners, while shyer listeners verbalized less encouragement. Findings provide insight into how temperamental shyness influences interactions within a structured communicative setting. • Examined the dyadic effect of shyness on children's own and their social partners' communicative behaviours. • Used a relevant context for school-aged children: a collaborative, goal-directed task with specific communicative roles ("instructor" and "listener"). • Shyer children produced fewer instructional statements when in instructor role. • Children attuned their communicative behaviours to the shy temperament of their unfamiliar social partner. • Dyadic association between shyness and communication varied by social role and experience with the task.

The purpose of this study was to examine the associations between maternal reports of social fear at 24 months and social behaviors with an unfamiliar peer during play at 36 months, using the Actor-Partner Interdependence Model (APIM; Kashy & Kenny, 1999). The APIM model was used to not only replicate previous findings of direct effects of early social fear on children's own social behavior (i.e., actor effects), but also to extend these findings by examining whether children's early social fear relates to an unfamiliar peer's behavior at 36 months (i.e., partner effects). Results revealed that social fear was associated with lower levels of children's own social engagement as well as less social engagement and dysregulated behavior in their play partners. These findings show that toddlers' social interactive behaviors are interdependent and reflect unique contributions of both the individual and their social partner's characteristics. In contrast, social fear was associated with children's own social wariness with the unfamiliar peer, but not their play partners' wariness. We discuss findings in terms of the influence of early social fear on young children's interpersonal environments and the potential role of these altered environments in supporting continuity of social fear and wariness over time.
