Japanese and U.S. preschool children's responses to hypothetical inter
personal dilemmas were examined as a function of culture, gender, and
maternal child-rearing values. U.S. children showed more anger, more a
ggressive behavior and language, and underregulation of emotion than J
apanese children, across different contexts of assessment. Children fr
om the 2 cultures appeared more similar on prosocial and avoidant patt
erns, though in some contexts U.S. children also showed more prosocial
themes. Girls from both cultures expressed more prosocial themes and
sometimes more anger than boys. Maternal encouragement of children's e
motional expressivity was correlated with anger and aggression in chil
dren. It was more characteristic of U.S. than Japanese mothers, while
emphasis on psychological discipline (reasoning; guilt and anxiety ind
uction) was more characteristic of Japanese than U.S. mothers. The rel
evance of a conceptual framework that focuses on differences in Easter
n and Western cultures in self-construals regarding independence and i
nterdependence is considered.
