肥胖与对未来的大幅折扣和增加食物强化有关。情景未来思维(Episodic future thinking, EFT)是一种前瞻性思维,可以减少延迟折扣(delay discount, DD),改善饮食决策。相反,负收入冲击(即突然过渡到贫困)已被证明会增加折扣,并可能使饮食决策恶化。评估了EFT培训的可扩展性以及EFT对模拟收入负冲击对DD和粮食需求的保护作用。在两个实验中,我们发现在线管理的EFT可以可靠地减少DD。此外,EFT即使在受到负收入冲击的挑战时也可以减少DD和对快餐的需求。我们的研究结果表明,EFT是一种可扩展的干预措施,通过减少对未来的折扣和对高能量密度食品的需求,对改善公众健康有影响。
Obesity is associated with steep discounting of the future and increased food reinforcement. Episodic future thinking (EFT), a type of prospective thinking, has been observed to reduce delay discounting (DD) and improve dietary decision making. In contrast, negative income shock (i.e., abrupt transitions to poverty) has been shown to increase discounting and may worsen dietary decision-making. Scalability of EFT training and protective effects of EFT against simulated negative income shock on DD and demand for food were assessed. In two experiments we showed online-administered EFT reliably reduced DD. Furthermore, EFT reduced DD and demand for fast foods even when challenged by negative income shock. Our findings suggest EFT is a scalable intervention that has implications for improving public health by reducing discounting of the future and demand for high energy dense food.
