共同进食影响食物消费的“双刃剑”效应及作用机制
人们在生活中与他人一起就餐的社会性进食行为即为共食。本文基于心理学视角辨析了共食与其他相关概念之间的联系与区别，归纳了共食的类型。同时，本文提出共食影响食物消费的“双刃剑”效应及不同类型的共食在进食行为上的差异模型。根据该模型，共食在不同理论视角下可能促进个体的健康饮食（积极效应），也可能导致个体产生不健康的进食行为（消极效应）。未来研究应深入探讨如何助推并削弱共食对食物消费的消极影响、运用前沿技术探究多元交互的共食及探究共食后的情绪感知以整合共食与其他进食行为的优势，进而完善共食的心理学理论模型。

People usually eat with others in their daily life, which is referred to as eating together. By reviewing the relevant literature, we discriminate the relationship and difference between concepts of eating together and joint consumption as well as co-experiencing from the psychological perspective, and also summarize different types of eating together. Moreover, in this paper, we propose a model that describes the double-edged sword effect of eating together on food consumption and the differences in eating behaviors between different types of eating together. According to this model, eating together may promote healthy eating (positive effect) or lead to unhealthy eating behaviors (negative effect) under different theoretical perspectives. Future research should further investigate how to attenuate the negative effects of eating together on food consumption via the nudge theory, explore the multiple interaction of eating together by utilizing cutting-edge technologies, and explore the influence of eating together on emotions to integrate the strengths of eating together and other eating behaviors, so as to establish a more detailed psychological model of eating together.
