Social versus non-social behavioral inhibition: Differential prediction from early childhood of long-term psychosocial outcomes.

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.

Effects of foster care intervention and caregiving quality on the bidirectional development of executive functions and social skills following institutional rearing.

Institutional rearing negatively impacts the development of children's social skills and executive functions (EF). However, little is known about whether childhood social skills mediate the effects of the foster care intervention (FCG) and foster caregiving quality following early institutional rearing on EF and social skills in adolescence. We examined (a) whether children's social skills at 8 years mediate the impact of the FCG on the development of EF at ages 12 and 16 years, and (b) whether social skills and EF at ages 8 and 12 mediate the relation between caregiving quality in foster care at 42 months and subsequent social skills and EF at age 16. Participants included abandoned children from Romanian institutions, who were randomly assigned to a FCG (n = 68) or care as usual (n = 68), and a never-institutionalized group (n = 135). At ages 8, 12, and 16, social skills were assessed via caregiver and teacher reports and EF were assessed via the Cambridge Neuropsychological Test Automated Battery. Caregiving quality of foster caregivers was observed at 42 months. FCG predicted better social skills at 8 years, which in turn predicted better EF in adolescence. Higher caregiver quality in foster care at 42 months predicted better social skills at 8 and 12 years, and better EF at 12 years, which in turn predicted 16-year EF and social skills. These findings suggest that interventions targeting caregiving quality within foster care home environments may have long-lasting positive effects on children's social skills and EF.

Parenting and childhood irritability: Negative emotion socialization and parental control moderate the development of irritability.

Irritability, characterized by anger in response to frustration, is normative in childhood. While children typically show a decline in irritability from toddlerhood to school age, elevated irritability throughout childhood may predict later psychopathology. The current study (n = 78) examined associations between trajectories of irritability in early childhood (ages 2-7) and irritability in adolescence (age 12) and tested whether these associations are moderated by parenting behaviors. Results indicate that negative emotion socialization moderated trajectories of irritability - relative to children with low stable irritability, children who exhibited high stable irritability in early childhood and who had parents that exhibited greater negative emotion socialization behaviors had higher irritability in adolescence. Further, negative parental control behavior moderated trajectories of irritability - relative to children with low stable irritability, children who had high decreasing irritability in early childhood and who had parents who exhibited greater negative control behaviors had higher irritability in adolescence. In contrast, positive emotion socialization and control behaviors did not moderate the relations between early childhood irritability and later irritability in adolescence. These results suggest that both irritability in early childhood and negative parenting behaviors may jointly influence irritability in adolescence. The current study underscores the significance of negative parenting behaviors and could inform treatment.

Pathways from maternal shyness to adolescent social anxiety.

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.

Bidirectional and interactive effects of child temperament and parenting in early childhood on the trajectory of social anxiety in adolescence.

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.

Trajectories of socially anxious behavior from age 5 to 13: Temperamental and sociocognitive pathways.

The authors examined temperamental and sociocognitive predictors of socially anxious behavior from preschool to early adolescence. Children (N = 227; 59% male; 69% White) completed a speech task at ages 5, 7, 10, and 13 and socially anxious behaviors were coded. Behavioral inhibition (BI) was assessed at ages 2/3 and Theory of Mind (ToM) was assessed at age 4. Data collection occurred between 2003 and 2016. Three trajectories of socially anxious behavior were identified: high stable, average increasing, and low stable. Higher BI was related to the high stable trajectory, whereas lower ToM was related to the increasing trajectory of socially anxious behavior. There are heterogenous pathways of socially anxious behavior, which may be uniquely influenced by early temperamental and sociocognitive factors.

Screen time and developmental health: results from an early childhood study in Canada.

BACKGROUND: Research has shown that longer hours of screen time are negatively associated with children's healthy development. Whereas most research has focused on school-age children, less is known about this association in early childhood. To fill this gap, we examined the association between screen time and developmental health in preschool-aged children. METHODS: This study draws from a data linkage on children (N = 2983; Mean age = 5.2, SD = 0.3 years, 51% male) in British Columbia (BC), Canada, who entered Kindergarten in public elementary schools in 2019. Parent reports on children's screen time, health behaviors, demographics, and family income collected upon kindergarten entry (09/2019), were linked to teacher reports on children's developmental health, collected halfway through the school year (02/2020). Screen time was assessed with the Childhood Experiences Questionnaire. Developmental vulnerability versus developmental health in five domains (physical, social, emotional, language and cognition, and communication skills) was measured with the Early Development Instrument. RESULTS: Logistic regression analyses using generalized estimating equation showed that children with more than one hour of daily screen time were more likely to be vulnerable in all five developmental health domains: physical health and wellbeing (odds ratio [OR] =1.41; 95% confidence interval [CI], 0.99 - 2.0; p=0.058), social competence (OR=1.60; 95% CI, 1.16 - 2.2; p=0.004), emotional maturity (OR=1.29; 95% CI, 0.96 - 1.73; p=0.097), language and cognitive development (OR=1.81; 95% CI, 1.19 - 2.74; p=0.006) and communication skills (OR=1.60; 95% CI, 1.1 - 2.34; p=0.015) compared to children reporting up to one hour of screen time/day. An interaction effect between income and screen time on developmental health outcomes was non-significant. Results were adjusted for child demographics, family income, and other health behaviors. CONCLUSIONS: Daily screen time that exceeds the recommended one-hour limit for young children, as suggested by the Canadian 24-h Movement Guidelines for Children and Youth (Tremblay et al. BMC Public Health. 17:874, 2017; Tremblay J Physical Activity Health. 17:92-5, 2020) is negatively associated with developmental health outcomes in early childhood. Screen-based activities should thus be limited for young children. Future research needs to examine the underlying mechanisms through which screen time is linked to developmental vulnerabilities.

Long-Term Effects of Institutional Care and Enhanced Attachment Relationships on Close Adolescent Friendships.

This study examined whether early institutional rearing and attachment security influence the quality and quantity of friendships at age 16 in 138 participants, including children abandoned to institutions in Bucharest, Romania, who were randomized to care as usual (n = 45, 26 female), or foster care (n = 47, 25 female), and a never-institutionalized group (n = 46, 18 female). Adolescents in the foster care group with secure attachment to their foster mothers at 42 months were comparable to never-institutionalized adolescents in having more friends and more positive behaviors with their friend during dyadic interactions, compared to the foster care group with insecure attachment and care as usual group. Interventions targeting early child-caregiver attachment relationships may help foster the ability to build positive friendships in adolescence.

Transactional Associations Between Parent and Late Adolescent Internalizing Symptoms During the COVID-19 Pandemic: The Moderating Role of Avoidant Coping.

Extensive research has demonstrated the transactional nature of parent-child psychopathology, with limited studies examining these effects during late adolescence and none, to our knowledge, longitudinally during the COVID-19 pandemic. The current study examined the cross-lagged effects of parent and adolescent internalizing symptoms during the COVID-19 pandemic and the moderating role of avoidant coping. A sample of 291 adolescents (Age mean = 18.27; 53% female; 61% White) and their parents rated their own anxiety and depressive symptoms and coping during the first two months following stay-at-home orders during the COVID-19 pandemic. Parent internalizing symptoms at the first assessment predicted adolescent internalizing symptoms at the second assessment. Adolescent avoidant coping style moderated this effect of parent internalizing symptoms on adolescent internalizing symptoms in the subsequent month, such that parent internalizing symptoms predicted child internalizing symptoms only among adolescents with moderate to high rates of avoidant coping. Follow-up analyses indicated different patterns when examining depressive and anxiety symptoms separately. The results highlight complex family dynamics between adolescents and their parents and begin to differentiate how individual characteristics impact the response to a significant life event such as the COVID-19 pandemic.

The Impact of Caregiving Disruptions of Previously Institutionalized Children on Multiple Outcomes in Late Childhood.

This study examined disruptions in caregiving, as well as the association of these disruptions, with cognitive, behavioral, and social outcomes at age 12 in a sample of 136 Romanian children who were abandoned to institutions as infants and who experienced a range of subsequent types of care. Children were found to experience significantly more caregiving disruptions (CGD) earlier in life than later in childhood. More frequent CGD predicted increases in externalizing and internalizing behavior problems at age 12. Results are discussed in terms of the association between CGD and the long-term development of children who have experienced institutional rearing.

Caregiving Disruptions Affect Growth and Pubertal Development in Early Adolescence in Institutionalized and Fostered Romanian Children: A Randomized Clinical Trial.

OBJECTIVES: To determine the effects of foster care vs institutional care, as well as disruptions in the caregiving environment on physical development through early adolescence. STUDY DESIGN: This was a randomized controlled trial of 114 institutionalized, though otherwise healthy, children from 6 orphanages and 51 never institutionalized control children living in birth families (family care group) in Bucharest, Romania. Children were followed from baseline (21 months, range 5-31) through age 12 years for caregiving disruptions and growth trajectories and through age 14 years for pubertal development. RESULTS: Children randomized to the foster care group showed greater rates of growth in height, weight, and body mass index (BMI) through age 12 years than institutionalized group. Tanner development was delayed in institutionalized group boys compared with foster care group and family care group boys at 12 but not 14 years. There were no differences in Tanner development and age of menarche among foster care group, institutionalized group, and family care group girls at ages 12 and 14 years. More disruptions in caregiving between 30 months and 12 years moderated decreases in growth rates of height in foster care group and weight in foster care group and institutionalized group across age. institutionalized group boys with ≥2 disruptions showed lower Tanner scores at age 12 vs institutionalized group and foster care group boys with <2 disruptions. foster care group girls with ≥2 disruptions had higher Tanner scores at age 14 vs foster care group girls with <2 disruptions. Age of menarche was not affected by caregiving disruptions. CONCLUSIONS: For children who experienced early institutionalization, stable placement within family care is essential to ensuring the best outcomes for physical developmental. TRIAL REGISTRATION: clinicaltrials.gov: NCT00747396.

Effects of early intervention and the moderating effects of brain activity on institutionalized children's social skills at age 8.

The present study examined the social skills of previously institutionalized, 8-y-old Romanian children from the Bucharest Early Intervention Project and the influence of attachment security and brain electrical activity (alpha power) on these skills. Participants included children randomized to an intervention involving foster care [Foster Care Group (FCG)], children randomized to remain in institutions [Care As Usual Group (CAUG)], and never-institutionalized children living with their families in the Bucharest community [Never-Institutionalized Group (NIG)]. A continuous rating of children's attachment security to their primary caregiver was assessed at 42 mo of age. When children were 8 y old, teachers rated their social skills, and the children's resting electroencephalogram alpha power was recorded. Teachers rated social skills of FCG children who were placed into foster care before 20 mo of age as no different from NIG children, and both of these groups were higher than CAUG children and FCG children placed after 20 mo. Electroencephalogram alpha power at age 8 significantly moderated the relations between attachment security and social skills. These findings characterize institutionalized children's social skills in middle childhood within the context of a randomized intervention while highlighting the roles of both relational and biological factors in these developmental trajectories.

Encouraging a Peer in Need: The Impacts of Social Anxiety and Peer Familiarity.

Extant research has produced conflicting findings regarding the link between social fearfulness and prosocial behavior, with some studies reporting negative relations and others reporting null effects. Furthermore, these studies have focused predominantly on toddlerhood, and few have examined prosociality between peers. The present study investigated whether the link between social anxiety and a prosocial behavior (i.e., providing encouragement) varied depending on interpersonal and situational factors (i.e., one's familiarity with a peer, the level of support sought by a peer, respectively). We tested this question using a multimethod approach, which included an ecologically valid stress inducing task and dyadic design with a sample of 9- to 10-year-olds (N = 447). Results revealed that social anxiety was related negatively to providing encouragement among familiar and unfamiliar dyads. In familiar dyads, however, this main effect was qualified by an interaction with the level of support sought by one's peer. Compared to those low in social anxiety, children high in social anxiety provided relatively less encouragement in response to higher levels of support seeking from their peers. The findings are considered in relation to theorizing regarding the effect of overarousal on children's prosocial behavior.

Which Anxious Adolescents Were Most Affected by the COVID-19 Pandemic?

Although the COVID-19 pandemic caused significant stress and anxiety among many, individuals' experiences varied. We examined if specific forms of anxiety predicted distinct trajectories of anxiety, perceived stress, and COVID-related worries during three early months of the pandemic. In a longitudinal study (N = 291), adolescents' (n = 194) social and generalized anxiety levels were assessed via parent- and self-reports and clinical diagnostic interviews. In young adulthood (n = 164), anxiety, stress, and COVID-related worries were assessed thrice during the pandemic. Pre-pandemic generalized anxiety predicted higher initial levels and maintenance of anxiety, stress, and COVID-related worries during the pandemic. In contrast, pre-pandemic social anxiety predicted lower initial levels of anxiety, stress, and COVID-related worries, but this initial effect on anxiety and stress was offset over time by social anxiety's positive effect on the slope. Our results highlight the importance of understanding how pre-pandemic factors influence individuals' experiences during the pandemic.

A Developmental Pathway From Early Behavioral Inhibition to Young Adults' Anxiety During the COVID-19 Pandemic.

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.Reprinted from J Am Acad Child Adolesc Psychiatry, 60, Zeytinoglu et al., A Developmental Pathway From Early Behavioral Inhibition to Young Adults' Anxiety During the COVID-19 Pandemic, pp. 1300-1308, copyright 2021, with permission from Elsevier.

Neurocognitive Profiles in Adolescence Predict Subsequent Anxiety Trajectories During the COVID-19 Pandemic.

BACKGROUND: The COVID-19 pandemic has created increased stress and anxiety for many; however, some individuals are particularly prone to heightened anxiety. It is unclear if and how prestress neurocognitive factors moderate risk for anxiety during high-stress situations. Enhanced error monitoring and a cognitive control strategy of more instantaneous (reactive) control have both been independently related to anxiety. We examined if a specific neurocognitive profile characterized by heightened error monitoring and a more reactive cognitive control strategy in adolescence predicts young adults' anxiety trajectories across 3 early months of the COVID-19 pandemic. METHODS: As part of a longitudinal study (N = 291), data were acquired in adolescence (13 years) on error monitoring (n = 124) and cognitive control strategy (n = 119). In young adulthood (18 years), anxiety was assessed three times during the COVID-19 pandemic (n = 162). RESULTS: On average, participants experienced greater anxiety in the first COVID-19 pandemic assessment, then anxiety decreased in the following months. Error monitoring and cognitive control strategy interacted to predict anxiety trajectories, such that among adolescents with an increased reliance on reactive control, error monitoring predicted greater anxiety in the first assessment but greater decreases the following months as stay-at-home orders were lifted and families adapted to the restrictions. CONCLUSIONS: Results suggest that neurocognitive profiles in adolescence predict young adults' anxiety responses during a highly stressful period, such as the initial months of the COVID-19 pandemic. Our findings have implications for the early identification of individuals at greater risk for anxiety.

The effects of severe psychosocial deprivation and foster care intervention on cognitive development at 8 years of age: findings from the Bucharest Early Intervention Project.

BACKGROUND: Previous reports from the Bucharest Early Intervention Project suggested that children removed from institutions and placed into intervention displayed gains in IQ relative to children randomized to remain in institutional care. METHOD: The current report presents data from the 8-year follow-up of these children. One hundred and three of the original 136 children in the study were tested with the WISC IV. RESULTS: Results reveal continued benefit from the intervention even though many of the children in both the intervention and control groups were no longer residing in their initial placements. Gains in IQ were particularly evident for those children who remained with their intervention family. There were also modest timing effects such that children placed earlier displayed higher scores on the WISC processing speed subscale. Early placement was also a significant predictor of a profile of stable, typical IQ scores over time. CONCLUSION: These data suggest the continued importance of early intervention and the negative effects of severe psychosocial deprivation on the development of IQ scores across early childhood.

Social determinants of playing outdoors in the neighbourhood: family characteristics, trust in neighbours and daily outdoor play in early childhood.

OBJECTIVES: The goal of this study was to investigate socio-demographic and contextual factors in relation to the frequency of outdoor play in the neighbourhood in early childhood, drawing from a large sample of children in British Columbia, Canada. METHODS: Parents/caregivers of 2280 4- to 5-year-old children completed the Childhood Experiences Questionnaire (CHEQ) in 2018. Binary logistic regression analyses were conducted to predict the likelihood of children participating in everyday outdoor play in their neighbourhood based on the child's gender, family ethnicity (i.e., European origin vs. other), household income (i.e., less vs. equal/more than CDN$75,000), population centre (i.e., urban vs. rural) and parent's trust in neighbours (i.e., trusting vs. not trusting neighbours to look out for children). RESULTS: Thirty-five percent of children in this study met recommendations of playing outdoors every day. Children whose parents perceived strong trust in neighbours were twice as likely to play outdoors in their neighbourhood every day, when compared with those whose parents perceived low trust in neighbours. Additionally, children from families with higher incomes (equal/more than $75,000) were significantly more likely to play outdoors daily than those with lower incomes, but only if they resided in rural areas. Last, children with European family backgrounds were 64% more likely to play outdoors every day compared with those with non-European backgrounds. CONCLUSION: Findings from this study contribute to an emerging body of work examining socio-economic, demographic and contextual factors associated with children meeting the recommendations for everyday outdoor play in their neighbourhood.

RéSUMé: OBJECTIFS: Le but de la présente étude était d'étudier les facteurs sociodémographiques et contextuels liés à la fréquence de jeu en plein air dans le quartier pendant la petite enfance, à partir d'un vaste échantillon d'enfants de la Colombie-Britannique, au Canada. MéTHODES: Les responsables de 2 280 enfants de quatre à cinq ans ont rempli le Childhood Experiences Questionnaire (CHEQ) en 2018. Des analyses de régression logistique binaire ont été effectuées pour prédire la probabilité que les enfants participent à des jeux extérieurs quotidiens en fonction du genre de l'enfant, de l'origine ethnique de la famille (c.-à-d. origine européenne ou autre), du revenu du foyer (c.-à-d. inférieur ou égal/supérieur à 75 000 $ CA), du centre de la population (c.-à-d. urbain ou rural) et de la confiance des parents envers les voisins (c.-à-d. confiance ou non dans les voisins pour veiller sur les enfants). RéSULTATS: Trente-cinq pour cent des enfants ont joué dehors au quotidien. Les enfants dont les parents ont perçu une forte confiance dans les voisins étaient deux fois plus probables de jouer dehors. De plus, les enfants issus de familles aux revenus plus élevés étaient nettement plus susceptibles de jouer dehors, mais seulement s'ils résidaient dans des régions rurales. Enfin, les enfants de familles européennes étaient 64 % plus probables de jouer dehors au quotidien. CONCLUSION: Les résultats de cette étude contribuent à un nouveau corpus de recherches examinant les facteurs socio-économiques, démographiques et contextuels associés au jeu en plein air au quotidien pendant la petite enfance.

Early institutionalization: neurobiological consequences and genetic modifiers.

Children raised in the profound deprivation associated with institutionalization are at elevated risk for negative outcomes across a host of social and cognitive domains. This risk appears to be mitigated by early foster care or adoption into a family setting. Although pervasive developmental problems have been noted in a substantial proportion of previously institutionalized children, marked variation exists in the nature and severity of these deficits. Increasing evidence suggests that institutional deprivation impacts the developing brain, potentially underlying the wide range of outcomes with which it is associated. In the current review we examine the neural consequences of institutionalization and genetic factors associated with differences in outcome in an effort to characterize the consequences of early deprivation at a neurobiological level. Although the effects of institutional deprivation have been studied for more than 50 years much remains unanswered regarding the pathways through which institutionalization impacts child development. Through a more complete and nuanced assessment of the neural correlates of exposure and recovery as well as a better understanding of the individual factors involved we will be better able to delineate the impact of early adversity in the setting of severe social deprivation.
