Continuities in emotion understanding from three to six years.

As part of a longitudinal study, 47 children who were tested on their understanding of basic emotions when they were 3 years old were tested again at 6 on their understanding of conflicting emotions. Significant stability in individual differences was found over this 3-year period. Antecedents to emotion understanding at 3 continued to be significantly related to children's understanding at 6, including participation in discourse about causality, positive interaction with older siblings, and language ability. Girls outperformed boys, and there was a suggestion that the girls' understanding of emotions was more closely associated than the boys' with the quality of their sibling relationships. Children's concurrent reports of negative experiences at home and at school were related to their sensitivity to the experience of ambivalent emotions. The results are discussed with respect to the social origins and implications of this core aspect of children's social-cognitive development.
