Obese (n = 20) and normal weight (n = 20) children (8-11 years) were compared using the delay of gratification paradigm. All children were asked to choose between an immediate reward or a larger delayed (one day) reward. Half the children were offered an edible incentive and half a non-edible incentive. Results showed that the obese choose immediate rewards more often than normals only when the incentive was edible. This suggests that deficits in delay of gratification shown by obese children are not generalized dispositions but are specific to food. A second aspect of the study examined preference for food vs non-food items and activities. Normals showed a much stronger preference for non-food items, nutritious foods and non-food related activities than the obese. This suggests that the deficits in delay of gratification shown by the obese children for food related items may be due to the stronger incentive value of these items for them.
采用延迟满足范式对20名肥胖儿童（8至11岁）和20名正常体重儿童进行了比较。所有儿童都被要求在即时奖励和更大的延迟（一天）奖励之间做出选择。一半儿童被提供可食用奖励，另一半被提供不可食用奖励。结果显示，只有当奖励是可食用的时，肥胖儿童比正常儿童更常选择即时奖励。这表明肥胖儿童表现出的延迟满足缺陷并非普遍倾向，而是特定于食物的。该研究的第二个方面考察了对食物与非食物物品及活动的偏好。正常儿童对非食物物品、营养食物和非食物相关活动的偏好远强于肥胖儿童。这表明肥胖儿童对与食物相关物品表现出的延迟满足缺陷可能是由于这些物品对他们具有更强的激励价值。
