title: Negative affectivity predicts individual differences in decision making for preschoolers.
abstract: The authors' goal in conducting this study was to explore the association between temperament and future-oriented decision making. Forty-three preschoolers (mean age = 51 months) were given a child variant of the Iowa Gambling Task (IGT) and asked to choose between a deck with higher immediate rewards and a deck with higher future rewards. Children who were higher on the Extraversion/Surgency factor of the Child Behavior Questionnaire chose more frequently from the higher immediate rewards deck early in the game. The externalizing dimension of Negative Affectivity (anger/frustration, soothability and discomfort) made the greatest contribution to prediction of performance in the last block of the game. Children who were more easily frustrated and had difficulty regulating negative emotions chose more from the deck with higher immediate rewards. There was a significant interaction between the externalizing dimension of Negative Affectivity, the internalizing dimension of Negative Affectivity (sadness and fear) and Extraversion/Surgency on the last block. These results suggest a complex association between IGT performance and temperament in preschoolers.
