This study examined relations between behavioral inhibition (BI) assessed in toddlerhood (n = 268) and attention biases (AB) to threat and positive faces and maternal-reported anxiety assessed when children were 5-and 7-year-old. Results revealed that BI predicted anxiety at age 7 in children with AB toward threat, away from positive, or with no bias, at age 7; BI did not predict anxiety for children displaying AB away from threat or toward positive. Five-year AB did not moderate the link between BI and 7-year anxiety. No direct association between AB and BI or anxiety was detected; moreover, children did not show stable AB across development. These findings extend our understanding of the developmental links among BI, AB, and anxiety.
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 seven 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 two and three years). Anxiety problems and social reticence were measured at seven 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.
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 two and three, and then assessed social reticence in these same children as they interacted with an unfamiliar, same age, and 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.
This study examined emotion regulation (ER) as a mediator in the relation between early behavioral inhibition (BI) and later social competence (N= 257), and whether this mediation varied depending on BI levels. Maternal-report and observational measures were used to assess BI (ages 2 and 3). Children’s ER strategies (age 5) and social competence with an unfamiliar peer (age 7) were measured using observational measures. Results showed that BI predicted less engaged ER strategies during a disappointment task, and engaged ER predicted higher social competence. Engaged ER mediated the effect of BI on social competence, but only for highly inhibited children. Findings elucidate developmental trajectories of risk and resilience and suggest targeting regulatory strategies in early prevention efforts with highly inhibited children.
The present study compared the social behaviors of 8-year-old previously institutionalized Romanian children from the Bucharest Early Intervention Project (BEIP) in two groups: 1) children randomized to foster care homes (FCG), and 2) children randomized to care as usual (remaining in institutions) (CAUG). Children were observed interacting with an age and gender-matched unfamiliar, non-institutionalized peer from the community (NIG) during six interactive tasks, and their behavior was coded for speech reticence, social engagement, task orientation, social withdrawal, and conversational competence. Group comparisons revealed that FCG children were rated as significantly less reticent during a speech task than CAUG children. For CAUG children, longer time spent in institutional care was related to greater speech reticence and lower social engagement. Using an Actor-Partner Interdependence Model, CAUG children's behaviors, but not FCG, were found to influence the behavior of unfamiliar peers. These findings are the first to characterize institutionalized children's observed social behaviors towards new peers during middle childhood and highlight the positive effects of foster care intervention in the social domain.
