Cross-cultural differences in emotional expressions following disappointment were examined in 59 Chinese American (CA) and 58 European American (EA) children. Children aged four or seven participated in a disappointing gift situation. Dimensions of expressive behaviors following disappointment were coded and included positive, negative, social monitoring, and tension behaviors. Significant main effects emerged for ethnicity and age, with EA children and older children demonstrating more positive behaviors than CA children and younger children, respectively. Younger children also demonstrated significantly more negative behaviors than older children. This main effect was qualified by a nearly significant age by ethnicity interaction, indicating developmental differences in the negative expressions for the EA group, but not for the CA group. Among the CA group, child adaptation of Western values was inversely associated with negative expressions, and a positive trend was found for positive expressions. Statistical trends were also found in which boys demonstrated more negative behaviors than girls and in which EA children demonstrated more total expressive behaviors than CA children. Implications of these findings are discussed with regard to cultural and familial processes, as well as cultural variation in children's cognitions about emotions. (Contains 1 table and 1 footnote.)
