Novel ways to increase liking and intake of food are needed to encourage acceptance of healthier food. How enjoyable we remember food to have been is likely to be a significant predictor of food choice. Two studies examined whether remembered enjoyment of eating a food can be increased and whether this makes individuals more likely to eat that food in the future. In Study One, a simple manipulation of instructing participants to rehearse what they found enjoyable about a food immediately after eating it was used to increase remembered enjoyment (relative to controls). In a separate study; Study Two, the effect of increasing remembered enjoyment on food choice was tested by examining whether the manipulation to increase remembered enjoyment resulted in participants choosing to eat more of a food as part of a later buffet lunch. The experimental manipulation increased remembered enjoyment for the food (Study One). A change in remembered enjoyment was shown to have a significant effect on the amount of a food participants chose to eat the following day for lunch (Study Two). The present studies suggest that remembered enjoyment can be increased via a simple act of rehearsal, resulting in a later increase in the amount of food chosen and eaten. Interventions based on altering remembered enjoyment of healthy food choices warrant further investigation.
需要寻找新的方法来增加对食物的喜爱和摄入量，以鼓励人们接受更健康的食物。我们对食物曾经的喜爱程度很可能是食物选择的一个重要预测因素。两项研究检验了是否可以增加对某种食物的记忆享受，以及这是否会使个体更有可能在未来食用该食物。在研究一，我们通过让参与者在食用后立即复述他们觉得享受的食物，来增加对食物的记忆享受（相对于对照组），从而进行了简单的操作。在另一项研究；研究二，通过检验增加记忆享受是否会导致参与者选择在之后的自助餐午餐中多吃某种食物，来测试增加记忆享受对食物选择的影响。实验操作增加了对食物的记忆享受（研究一）。结果显示，对食物的记忆享受的改变对参与者第二天午餐选择吃的食物数量有显著影响（研究二）。本研究表明，通过简单的复述行为，可以增加对食物的记忆享受，从而导致日后选择和食用的食物量增加。基于改变对健康食物选择的记忆享受的干预措施值得进一步研究。
