Parental play styles and sibling interaction during a problem-solving task

Associations between parental play styles and sibling interaction were investigated in 30 same-sex preschool- and school-aged sibling dyads (first-borns were 4–9 years, M=6.6 years; second-borns were 2–7 years, M=4.2 years), divided into older and younger sibling groups. Participants completed puzzles under three conditions: (a) siblings alone, (b) together with mother, and (c) together with father. Prosocial and agonistic sibling-directed behaviors and positive and negative parent–child behaviors were coded. Siblings engaged in both more prosocial and agonistic interactions when alone than with either parent; there were no differences in sibling interactions in the mother versus father episodes. Paternal negative behavior was associated with sibling agonistic behavior when the children were alone, indicating second-order effects, however, mother–child and sibling interactions were not significantly associated. Nevertheless, reciprocity in positive and negative behaviors directed by children to parents and vice versa was evident, demonstrating synchrony in patterns of exchanges. The findings underscore the necessity of studying both parents in order to understand more fully the dynamics involved in family relationships. Copyright © 1999 John Wiley & Sons, Ltd.
