Early childhood is characterized by robust developmental changes in cognitive control. However, our understanding of intra-individual change in neural indices of cognitive control during this period remains limited. Here, we examined developmental changes in event-related potential (ERP) indices of cognitive control from preschool through first grade, in a large and diverse sample of children (N = 257). We recorded ERPs during a visual Go/No-Go task. N2 and P3b mean amplitudes were extracted from the observed waveforms (Go and No-Go) and the difference wave (No-Go minus Go, or ∆). Latent growth curve modeling revealed that while N2 Go and No-Go amplitudes showed no linear change, P3b Go and No-Go amplitudes displayed linear decreases in magnitude (became less positive) over time. ∆N2 amplitude demonstrated a linear increase in magnitude (became more negative) over time whereas ∆P3b amplitude was more positive in kindergarten compared to preschool. Younger age in preschool predicted greater rates of change in ∆N2 amplitude, and higher maternal education predicted larger initial P3b Go and No-Go amplitudes in preschool. Our findings suggest that observed waveforms and difference waves are not interchangeable for indexing neurodevelopment, and the developmental trajectories of different ERP indices of cognitive control are component-specific in early childhood.

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.

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

Cognitive flexibility is a sophisticated form of executive functions that predicts a range of adaptive outcomes; however, little is known about which caregiving behaviors predict the rapid improvements in children's cognitive flexibility during early childhood. This study examined whether ordinary variations in mothers' provision of emotional and cognitive support during problem-solving predict children's cognitive flexibility and tested whether children's cognitive flexibility predicts caregiving behaviors across time. Two hundred and seventy-eight children and their caregivers (96% mothers) participated in laboratory visits when children were in preschool, kindergarten, and first grade. At each visit, cognitive flexibility was measured via a computerized version of the Dimensional Change Card Sort task and mothers' behaviors were observed during a semi-structured problem-solving board game task. Results from autoregressive cross-lagged structural regression analyses indicated that mothers' emotional support predicted greater child cognitive flexibility from preschool to kindergarten, and from kindergarten to first grade, after accounting for the stability in these constructs over time and controlling for the influence of maternal education, and child age and minority status. Mothers' cognitive support did not predict child cognitive flexibility over time. Child cognitive flexibility did not lead to changes in caregiving behaviors over time. Findings suggest that mothers' provision of emotional support during problem-solving may be an important proximal mechanism that contributes to children's cognitive flexibility across early childhood.

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.

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.

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.

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]

Although autonomic nervous system (ANS) functioning is "context‐dependent," few studies examined children's normative sympathetic and parasympathetic autonomic responses to distinct challenges in early childhood years. Examining children's ANS responsivity to distinct challenges is important for understanding normative autonomic responses toward everyday life stressors and identifying paradigms that effectively elicit a "stress response." We examined children's (N = 278) sympathetic (preejection period [PEP]) and parasympathetic (respiratory sinus arrhythmia [RSA]) responses to cognitive (i.e., problem‐solving and cognitive control) and negatively valenced emotional (i.e., blocked goal and unfairness) challenges in preschool, kindergarten, and grade 1. Children, on average, demonstrated parasympathetic inhibition (RSA withdrawal) in response to all challenges but the magnitude of these responses depended on the task. Children showed sympathetic activation (PEP shortening) toward the problem‐solving task at each assessment and there was no sample‐level change in the magnitude of this response over time. Children showed greater sympathetic responsivity toward the cognitive control task over time, with evidence for a sympathetic activation response only in grade 1. Children experienced sympathetic inhibition (PEP lengthening) toward the unfairness tasks but did not experience significant sympathetic responsivity toward the blocked goal tasks. Parasympathetic responsivity to most challenges were modestly stable but there was no stability in sympathetic responsivity across time. [ABSTRACT FROM AUTHOR]

This study examined whether children’s expression of gratitude and processes potentially related to this expression, such as wishes and spending preferences, would vary across childhood in an urban center of a majority world country. We collected data from 422 boys and girls aged 7 to 14 years residing in Izmir, Turkey. Results indicated that the expression of connective gratitude was common across all ages, and there was a decrease in the expression of concrete gratitude with an increase in age. There was no relationship between types of wishes and gratitude or wishes and spending preferences; however, girls expressed less concrete gratitude and fewer hedonistic wishes compared with boys. Saving and donating were the most common spending preferences, and with an increase in age, the tendency for spending money to buy things for oneself increased. These findings are discussed in relation to how cultural experiences may influence the development of gratitude in this population. [ABSTRACT FROM AUTHOR]
