Background: Individual differences in specific components of attention contribute to behavioral reactivity and regulation. Children with the temperament of behavioral inhibition (BI) provide a good context for considering the manner in which certain components of attention shape behavior. Infants and children characterized as behaviorally inhibited manifest signs of heightened orienting to novelty. The current study considers whether this attention profile moderates risk for clinical anxiety disorders among adolescents with a history of BI., Methods: Participants were assessed at multiple time points for BI, beginning in early childhood. At adolescence, event-related potentials (ERPs) were recorded during a three-stimulus auditory novelty oddball task, which employed frequent standard and infrequent deviant tones as well as a set of complex, novel sounds. Clinical diagnosis was carried out using the Schedule for Affective Disorders and Schizophrenia for School-Age Children-Present and Lifetime Version (K-SADS-PL). P3 and mismatch negativity (MMN) components were examined at midline frontal, central, and parietal electrode sites., Results: Individuals who displayed high levels of BI during childhood and increased P3 amplitude to novelty in adolescence were more likely to have a history of anxiety disorders compared to behaviorally inhibited adolescents with lower P3 amplitudes. Groups did not differ on measures of MMN., Conclusions: Increased neural responses to novelty moderate risk for anxiety disorders amongst individuals with a history of BI.

Background: We examined the effects of a foster care intervention on attention and emotion expression in socially deprived children in Romanian institutions., Methods: Institutionalized children were randomized to enter foster care or to remain under institutional care. Subsequently, the institutionalized and foster care groups, along with a community-based comparison group, were evaluated on emotion tasks at 30 and 42 months of age. Behaviors reflecting positive and negative affect and attention were coded from videotapes., Results: Data indicated that at both age points, children who received the foster care intervention showed higher levels of attention and positive affect compared to children who remained institutionalized. Compared to the community sample, children in the foster care intervention showed higher levels of attention to the emotion-eliciting tasks at 42 months of age., Conclusions: The results of this randomized trial demonstrate the impact of a family-based intervention on the development of attention and positive affect.

Background: We assess individual differences in the caregiving environments of young children being raised in institutions in Romania in relation to developmental characteristics such as physical growth, cognitive development, emotional expression, and problem and competence behaviors., Method: Videotaped observations of the child and favorite caregiver in their 'home' environment were coded for caregiving quality, and this was related to child characteristics. Child emotional reactivity was assessed during responses to interactional tasks. Cognitive development was assessed from child responses to the Bayley Scales of Infant Development. Data regarding problem behaviors and competence were obtained from caregiver report. Children reared in institutions were compared on all of these measures to never institutionalized children to assist gauging degree of impairment., Results: Children raised in institutions demonstrated marked delays in cognitive development, poorer physical growth, and marked deficits in competence. Individual differences in caregiving environment were associated with cognitive development, competence, and negative behavior among these young children being reared in institutions., Conclusions: These data confirm previous findings regarding deficits associated with institutional care and extend our understanding of the impact of individual differences in caregiving quality on the development of young children in institutions.

Four-year-old children showing low levels of social behavior in a laboratory play session with unfamiliar peers were classified as reticent (unoccupied or onlooking behaviors) or solitary-passive (solitary constructive or exploratory play). Compared with a group of more social children, the children in both low-social groups were rated high on maternal reports of shyness and displayed a pattern of right frontal EEG asymmetry. However, only the reticent group was elevated on measures indicative of a fearful temperament, both concurrently and retrospectively. A subset of children in the solitary-passive group showed increasing levels of reticent behavior over the course of the visit, suggesting that for some children solitary-passive behaviors provide a means for coping with feelings of unease.

Background: The primary objective of this study was to examine the extent to which both individual child temperament and parent-child relationship quality independently and/or interactively predicted physiological, psychosocial, and behavioral 'outcomes'. Employing a longitudinal prospective design over three years, statistical associations were found among infant attachment, uninhibited temperament, and 4-year behavioral and physiological functioning that supported a bio-psychosocial model of development., Method: Three cohorts totaling 140 children and their mothers visited the laboratory for observational assessments of attachment classification at age 14 months (Strange Situation), behavioral inhibition at 24 months, and social behaviors with unfamiliar peers at age 4 years. Cardiac measures of heart rate and respiratory sinus arrhythmia (RSA) were collected at every time point. At age 4 years maternal ratings of child temperament and behaviors were also obtained., Results: Analyses of variance (ANOVAs) with inhibition group (high, moderate, low) and attachment classification (A, B, C) revealed that the low inhibited group had significantly higher activity level scores and displayed significantly less reticence at 4 years compared to the moderately and highly inhibited groups. Infants who had an avoidant attachment with their mothers had more externalizing problems (aggressive behaviors) at age 4 than either securely or ambivalently attached infants. This predictive relation, however, was qualified by an interaction whereby avoidant attachment and uninhibited temperament together predicted a higher incidence of externalizing behavior problems. Moreover, infants' avoidant attachment was not concurrently but predictively associated with lower heart rate and high RSA at age 4 years. Therefore, an avoidant mother-child relationship in infancy could influence the development of an underaroused autonomic profile in early childhood., Conclusions: Consistent with bio-psychosocial models of development, these findings support the contention that both early child temperament and parent-child relationship quality contribute to subsequent psychological/behavioral and physiological functioning.

This study shows that relations between behavioral inhibition and cardiac activity may be clarified by identifying attachment status, whereas relations between security of attachment and cardiac activity may be clarified by identifying inhibition status. Assessments at 4.5 years (N = 126) included heart period (HP), respiratory sinus arrhythmia (RSA), behavioral inhibition (BI), and security of attachment. There was no main effect of BI status (Low, Medium, High) on either HP or RSA. Instead, it was only the Secure children who showed the predicted relation between low BI and high HP or RSA, with the Low BI-Secure group having significantly higher HP than either the High BI-Secure or the Low BI-Insecure groups. Turning to attachment, both HP and RSA increased significantly from an assessment during separation from mother to an assessment 3 min after reunion. The only subgroups showing a significant increase in HP, however, were those with both secure attachment and an absence of high BI.
