Abstract

Highlights: Portion size effect (PSE) influences the amount of food a person will consume. When looking at food consumption behavior, PSE should be a moderating factor. Using food-related cues to influence consumption in elderly consumers. Various food-related cues have mixed results in influence. Inconsistent effects of previous food consumption studies could be because of PSE. Abstract: Food-related cues can increase the time a person spends in the dining room. Increasing the time a person spends dining can improve their food intake. Studies on the use of music and olfactory cues have produced conflicting results. This study explores whether the portion size effect (PSE), the portion served, influences a person's consumption and can explain the inconsistent results. The study focused on testing this phenomenon with residents in an aged-care home. Malnutrition is often a problem with residents in aged-care facilities. Exposing the residents to various cues (music, olfactory and infographics) over seven weeks with different portions of food served. Results showed that the cues did not significantly impact, but PSE did, casting doubts on studies that did not control for the portion served. Discussions of the academic and managerial implications are also provided. Chinese Abstract: 食物相关的线索会增加一个人在餐厅用餐的时间. 增加一个人用餐的时间可以提高他们的食物摄入量. 之前关于使用音乐和嗅觉线索的研究产生了相互矛盾的结果. 这项研究探讨了份量大小效应 (PSE), 即所提供的份量, 是否会影响一个人的消费, 并能解释不一致的结果. 这项研究主要是在养老院的居民中测试这一现象. 营养不良通常是老年人护理机构的一个问题. 在七周的时间里, 我们让受试者接触不同的线索 (音乐, 嗅觉和信息图表), 并提供不同分量的食物. 结果显示, 这些线索没有显著影响, 但PSE却有, 这不禁让人们对那些没有控制食物份量的研究产生了怀疑. 最后, 我们讨论并提供了该研究在学术中和管理中的意义.
