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.

与食物有关的线索的有效性和份量效应

摘要与食物有关的线索可能会增加一个人在餐厅花费的时间。增加一个人用餐的时间可以改善他们的食物摄入量。关于音乐和嗅觉提示的使用的研究产生了矛盾的结果。这项研究探讨了份量大小效应（PSE），所份量是否影响人的消费并可以解释不一致的结果。该研究的重点是在养老院中的居民身上测试这种现象。营养不良通常是养老机构居民的问题。在七周的时间内，将居民暴露于各种线索（音乐，嗅觉和信息图表）中，并提供不同份量的食物。结果表明，提示并没有显着影响，但PSE却有影响，这对不能控制所服务部分的研究产生了怀疑。
