Preschoolers' emotional control in the disappointment paradigm and its relation to temperament, emotional knowledge, and family expressiveness.

The present research evaluated a conceptual model that links temperament, emotional knowledge, and family expressiveness to preschoolers' emotion regulation ability. The emotional understanding of 82 preschoolers was assessed with 2 separate tasks. After the second emotional knowledge task, the children were presented a "disappointing" prize, and their facial displays of positive and negative affect were recorded. The children and their mothers also participated in a game designed to elicit maternal expressive behavior. Mothers provided information about the preschoolers' temperament and about the frequency of positive and negative affect expressed within their families. Results indicated that children's positive displays when presented the "disappointing" prize were inversely related to the temperamental dimension of emotional intensity and positively associated with children's understanding of emotion. Maternal reports of sadness within the family were inversely related to children's positive affective displays. Children's negative emotional displays in the disappointment situation were inversely related to observed maternal positive emotion. The findings from this study give greater specification to the unique and joint contributions of temperament, emotional knowledge, and family expressiveness in predicting preschoolers' expressive control of emotion.
