Arguments and relationships within the family: Differences in young children's disputes with mother and sibling.

This study examined whether children's arguments differ in disputes with mother and with sibling as well as how arguments used in family interaction relate to later assessment of social understanding. Fifty children (age 33 months) were observed interacting with the mother and sibling in 2 visits in the child's home, and family conversation was recorded and subsequently transcribed. Results showed correlations between partners'arguments in conflict within dyads, but children's argument with their mothers was not related to that used when in dispute with their siblings. Children's use of argument with sibling was also predictive of sociocognitive performance assessed 7 months later
