行为经济学原理指出，随着产品成本的增加，购买或消费该产品将减少。为了理解行为经济学对摄食行为的影响，我们的实验室利用操作性行为范式来衡量一个人为了获得食物和饮料会付出多少努力。这项任务提供了一个客观的补强值测量。我们已经证明，连续两周每天食用相同的高脂肪零食会降低瘦人的强化价值，但会增加一部分肥胖人的强化价值。食物强化价值的增加预示着未来体重的增加。同样，我们已经证明，反复摄入含咖啡因的苏打水会增加男孩的强化价值，但对女孩却没有。这种强化值的增加与通常的咖啡因摄入无关，但可能与咖啡因的积极、主观影响有关，而男孩比女孩更有可能报告这种影响。由于食品和饮料的强化与现实世界的消费有关，确定增加或减少强化值的因素以及确定这些反应的后果是很重要的。我们特别感兴趣的是确定改变行为经济曲线的方法，以便开发新的策略来减少不太健康的零食和饮料（如苏打水、薯片和糖果）的强化价值，增加更健康的食品和饮料（如水、水果和蔬菜）的强化价值。
Behavioral economic principles state that as the cost of a product increases, purchasing or consumption of that product will decrease. To understand the impact of behavioral economics on ingestive behavior, our laboratory utilizes an operant behavior paradigm to measure how much work an individual will engage in to get access to foods and beverages. This task provides an objective measure of the reinforcing value. We have shown that consumption of the same high fat snack food every day for two weeks reduces its reinforcing value in lean individuals, but increases its reinforcing value in a subset of obese individuals. This increase in the reinforcing value of food predicts future weight gain. Similarly, we have shown that repeated intake of caffeinated soda increases its reinforcing value in boys, but not in girls. This increase in reinforcing value is not related to usual caffeine consumption, but may be associated with positive, subjective effects of caffeine that are more likely to be reported by boys than by girls. Because food and beverage reinforcement relates to real-world consumption, it is important to determine factors that increase or decrease the reinforcing value and determine the consequences of these responses. We are especially interested in determining ways to shift the behavioral economic curve in order to develop novel strategies to decrease the reinforcing value of less healthy snack foods and beverages, such as soda, potato chips and candy and to increase the reinforcing value of healthier foods and beverages, such a water, fruits, and vegetables.
