Children's understanding of marital conflict and the marital relationship w
as investigated in 60 children of 5, 7, and 9 years old. Age differences we
re hypothesized in four areas of children's understanding of marital confli
ct and the marital relationship, based on the development between 5 and 9 y
ears of age of children's abilities to (a) analyse complex sequences of beh
avior in terms of the mental states of protagonists and (b) integrate multi
ple social roles. The four areas investigated were: conceptions of marital
conflict, conflict resolution, family triangulation, and integration of the
spousal and parental roles. Children were read stories involving family in
teractions. Open-ended questions were asked about their understanding of th
ese interactions and a coding scheme was devised that reflected theoretical
concepts. Nine-year-olds differed from 5-year-olds on all aspects of their
understanding of marital conflict and the marital relationship, and 7-year
-olds showed levels of understanding between 5- and 9-year-olds. Younger ch
ildren were less likely than older children to explain marital conflict in
terms of the divergent goals of each parent: to understand conflict resolut
ion as dependent on one person changing their beliefs or goals, to understa
nd that parents were simultaneously spouses and parents and to understand t
he nature of triangulation. Marital conflict is interpreted very differentl
y by children of different ages.
