Delay of gratification in obese children.

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.
