: High delay discounting (DD), or the tendency to prefer immediate rewards over larger delayed rewards, has been associated with health risk behaviors. This study examined the DD of hyper-palatable foods (HPFs) and money, and their associations with eating motives and binge eating behavior. : An adult sample (N = 296) completed a DD task with single- and cross-commodity conditions with rewards of money and/or HPF (e.g., HPF now vs. HPF later; HPF now vs. money later). Regression models tested the association between DD, and eating motives and binge eating. : DD in the HPF now vs. money later condition was positively associated with the reward enhancement motive (β = 0.291; = 0.008) and binge eating behavior (β = 0.041; = 0.017). There were no other significant associations. : Decisional impulsivity specific to HPFs (and not decisional impulsivity in general) may be associated with reward-motivated eating and binge eating behavior.
高延迟折扣（DD），即相较于更大的延迟奖励更倾向于即时奖励的倾向，已与健康风险行为相关联。本研究考察了高适口性食物（HPF）和金钱的延迟折扣，以及它们与进食动机和暴饮暴食行为的关联。：一个成人样本（N = 296）在单商品和跨商品条件下完成了一项延迟折扣任务，奖励为金钱和/或高适口性食物（例如，现在的高适口性食物与稍后的高适口性食物；现在的高适口性食物与稍后的金钱）。回归模型检验了延迟折扣与进食动机和暴饮暴食之间的关联。：在现在的高适口性食物与稍后的金钱条件下的延迟折扣与奖励增强动机（β = 0.291；P = 0.008）和暴饮暴食行为（β = 0.041；P = 0.017）呈正相关。没有其他显著关联。：特定于高适口性食物的决策冲动性（而非一般的决策冲动性）可能与奖励驱动的进食和暴饮暴食行为相关。
