| Outline of Final Research Achievements |
The previous studies on science of food and eating behavior have shown that exposure to the image of a lower-weight person reduces food consumption among young adults. However, it remains unknown whether this paradigm could be adapted and applied to increase food intake among older adults with dementia by exposing them to the image of a higher-weight person to mitigate weight loss and malnutrition. Thus, the present study explored whether weight-related visual priming cues affect the amount of food consumed by older adults with dementia. In the experiment, older people with dementia living in a nursing home were visually exposed to cartoon images during daily lunch situations. Results demonstrate that participants finished their meals more frequently when they were exposed to the image of the higher-weight image than when they were not exposed to any images. These results imply that exposure to a higher-weight person increases food intake in older adults with dementia.

| Academic Significance and Societal Importance of the Research Achievements |
本研究は, 食行動の背景にある心理学的メカニズムへの関心と, 認知症高齢者の低栄養問題への支援策を模索する介護現場の声を結び付けて創出された研究プロジェクトである. 本研究成果は学術的新規性と, 認知症高齢者の食支援の現場に活用できる応用可能性を兼ね備えたものであり, 学術的・社会的意義が高い. 本研究で得られた学術的知見は, 食事に際して視覚情報が食物摂取行動に及ぼす影響を理解し, 認知症高齢者の十分な栄養摂取を促進する食卓環境をデザインする上で有益な基礎的資料の1つとなるであろう.
