The ability to delay gratification (DG) in young children is vital to their later development. Such ability should be taught as early as possible. One hundred kindergartners (Mean age = 6.11), randomly assigned to three groups; (a) labeling: received the treatment of being labeled as "patient" kids; (b) story-telling: were read a story about the patient antagonist rewarded double gifts, while the impulsive character got only one same reward; (c) control: received no treatment. Under the DG task of Ball-Moving Activity, the ANOVA results showed the children in labeling group delayed longer (M = 13.23 m) than the control one (M = 11.25 m), showed marginal significant difference at p = 0.06, medium effect size magnitude at eta[superscript 2] = 0.06. No significant mean differences were found between the story-telling (M = 12.68 m) and the control group, though the story-telling group delayed more than 1 min longer than their counterparts. Sex differences on the task are also discussed.
