Background: Although many children grow up with more than one sibling, we do not yet know if sibling dyads within families show similarities to one another on sibling affection and hostility. In the present study the hypotheses were tested that (a) there will be significant between family variation in change in sibling affection and hostility and…

Background: Previous studies have found that multiple factors are associated with parent-child relationship quality, but have not distinguished potential sources of between-family and within-family variation in parent-child relationship quality. Methods: Approximately equal numbers of biological (non-stepfamilies), single-mother, stepfather, and…

Developmental changes in the pattern of 50 families' conversations about feelings were examined when the families' second-born children were 33 and 47 months old. The total amount of talk and the frequency of talk about feelings between sibling pairs increased, whereas the amount of mother-child conversation and references to feelings decreased.…

Fifty second-born preschoolers and their families were observed at 3 intervals over a 14-month period to examine the relations between emotional expression in the family, children's understanding of emotions, and children's social understanding. Frequent expressions of anger or distress within the family when children were 33-months-old was…

Studied children's use of justification in disputes with their mothers and siblings and its relation to the social and emotional context of family disputes.

A longitudinal study of conflict management among siblings found that children's use of other-oriented statements emerged between 33 and 47 months of age, and that children used other-oriented arguments with their friends more often than with their mothers or siblings. Further, at 33 months, children used more reasoning during conflicts when not…

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)
