A critique of research examining whether early experiences with primary caregivers are reflected in adaptation is that relevant longitudinal studies have generally not employed genetically informed research designs capable of unconfounding shared genes and environments. Using the twin subsample (N = 485 pairs) of the Early Childhood Longitudinal…

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…

Infants participated in a nonsocial contingency task immediately after a social interaction with their mothers. The amount of time mothers and infants spent in a state of vocal turn-taking predicted individual differences in infants' subsequent performance on the contingency task. (PCB)

Examined relationship of emotion regulation and emotionality to social functioning in 77 children followed from age 4 to age 10. Found that high-quality social functioning was predicted by high emotion regulation and low nonconstructive coping, negative emotionality, and emotional intensity. Measures of regulation and emotionality frequently…

Assessed the role of maternal affect mirroring on development of prosocial behaviors and social expectancies in 2- to 3-month-olds. Found that infants whose mothers ranked high on affect mirroring (attention maintenance, sensitivity, responsiveness) ranked high on prosocial behaviors and social expectancy, whereas infants whose mothers ranked low…

Examined children's emotional and behavioral regulation and emotional and prosocial responses to a crying infant. Found that children who could regulate their arousal were unlikely to become distressed and more likely than other children to talk to and comfort the crying infant. Girls were more responsive and engaged in more active responses than…

Examined relations of children's regulation and emotionality to their social functioning. Found that resiliency mediated effects of individual differences in attentional regulation on social status and socially appropriate behavior, and that negative emotionality moderated the positive relation between attentional control and resiliency. Also…

Examined developmental changes in the ability of 83 children aged 3-12 to determine emotion by interpreting facial and situational cues. Results showed that children's reliance on situational cues increased with age, while reliance on facial expression decreased. (RJC)

Examined the emotional reactions of toddlers to two mishaps. Children's reactions varied along two dimensions: tension and frustration and concerned reparation. Mishaps elicited more negative emotions than did free play, and most toddlers attempted to correct the mishap. Findings indicate that children's styles of emotional response to mishaps may…

Reviews and considers the developmental implications of recent evidence on the nature of sibling interaction from observational studies of preschool children. Argues that, in contrast to complementary interaction, sibling influence is most plausibly associated with reciprocal interaction and with sociocognitive development. (Author/RH)
