Affect and delay of gratification

Abstract

Three experiments investigated the influence of positive and negative affect manipulations on children's preferences for small immediate versus large delayed rewards. Positive and negative affect were induced via verbal instructions to imagine happy and sad experiences. Elementary school children were randomly assigned to a control condition or to one of several treatment conditions consisting of two affect manipulations: a positive followed by a negative, the reverse, and (in the third experiment) two positives or two negatives. In some conditions (in the second and third experiments) measurement of delayed reward preference followed the first and second affect inductions whereas in other conditions (in the second and third experiments) measurement followed only the second affect manipulation. As predicted, negative affect subjects chose fewer large delayed rewards than did positive affect subjects during the first assessment (p < .02). At the second assessment, comparison among treatment and control conditions revealed the influence of a prior commitment effect which negated the potential influence of a second affect manipulation on preference for delayed rewards.
