This study examined the developmental profiles of children's social reasoning about individual agentive and deontic concerns. Tongan children (N = 140, 47.9% male), aged 4-8 years, were given a set of mentalistic (standard theory-of-mind) and deontic reasoning tasks. On average, children found diverse desires, knowledge access, hidden emotion, and…

Child maltreatment often has a negative impact on the development of social behavior and health. The biobehavioral mechanisms through which these adverse outcomes emerge, however, are not clear. To better understand the ways in which early life adversity affects subsequent social behavior, changes in the neuropeptide oxytocin (OT) in children…

The association among mothers', fathers', and infants' risk and cognitive and social behaviors at 24 months was examined using structual equation modeling and data on 4,200 on toddlers and their parents from the Early Childhood Longitudinal Study, Birth Cohort. There were 3 main findings. First, for cognitive outcomes, maternal risk was directly…

To test the hypothesis that biological motion perception is developmentally integrated with important social cognitive abilities, 12-month-olds (N = 36) were shown a display of a human point-light figure turning to observe a target. Infants spontaneously and reliably followed the figure's "gaze" despite the absence of familiar and socially…

This multimethod study of 101 mothers, fathers, and children elucidates poorly understood role of children's attachment security as "moderating" a common maladaptive trajectory: from parental power assertion, to child resentful opposition, to child antisocial conduct. Children's security was assessed at 15 months, parents' power assertion observed…

Neural correlates of social-cognition were assessed in 9- to- 17-year-olds (N = 34) using functional magnetic resonance imaging. Participants appraised how unfamiliar peers they had previously identified as being of high or low interest would evaluate them for an anticipated online chat session. Differential age- and sex-related activation…

Applied the concepts of agonism and dyadic dominance to the analysis of children's behavior. (SB)

Investigated the development of social referencing (children's looks toward parents, instrumental toy behaviors, affective expressions, etc.) in 40 infants aged 6-9, 10-13, and 14-22 months. Results indicated that looking behavior of younger children may function differently from that of older children, and social referencing involves a number of…

Studied 14 peer dyads at 16, 20, 24, 28, and 32 months to assess developmental changes in social coordinations. Results indicated a marked increase with age in acts coordinated with those of a peer. Imitations of the peer's nonverbal actions accounted for most of the developmental change. (RJC)

Examines the effect of changes in the social and motor capabilities of infants on their daily social encounters. Home observations were made of the social interactions of 14 infants and their mothers when the infants were 6, 8, and 12 months of age. (CM)

National Health Survey data of 12- to 17-year-olds were used to determine links between dating behavior and level of sexual maturation as well as age. Analyses indicated that individual levels of sexual maturation add very little to the explained variance in dating after age has been taken into account. (Author/DB)

Identifies reliable mother action-child reaction patterns and assesses the effect of maternal consequences for those patterns on the probability of their subsequent occurrence. (HOD)

Assessed the extent to which preferential personal attraction was associated with behavioral similarity among newly acquainted children. Found that "discriminating" children were more behaviorally similar to preferred playmates than nonpreferred playmates, both in terms of cognitive play style and social participation. (AA)
