Does liking or wanting predict the delay between consumption episodes? Although these psychological processes are correlated, we find that memory for liking, rather than wanting, determines the number of days that pass until the consumption of a food is repeated. Experiment 1 found that liking (but not wanting) for a food at the end of a consumption experience predicted how many days passed until participants wanted to consume it again. Experiment 2 showed that mitigating the decrease in liking resulting from the repeated consumption of a food eliminates its effect on delay. Together, these findings suggest that end liking has a greater influence on when people will consume a food again in the future.
喜欢或想要是否能预测消费间隔?尽管这些心理过程相关联,但我们发现,对喜欢的记忆,而不是想要的记忆,决定了从食物消费到再次消费的天数。实验 1 发现,在消费体验结束时对食物的喜欢(而不是想要)预测了参与者想要再次消费它需要多少天。实验 2 表明,减轻重复消费一种食物导致的喜欢程度下降,可以消除其对延迟的影响。总之,这些发现表明,结束时的喜欢对人们未来何时再次食用一种食物有更大的影响。
