The social facilitation of eating (i.e., people eating more in groups than when alone) has been studied for about three decades now. In this paper, we review the empirical research (diary studies, observational studies, and experimental studies) of social facilitation, attending to factors that increase or decrease socially facilitated eating. We also review the various explanations (e.g., "time extension") that have been offered for the effect and offer our own speculations as to the underlying mechanisms. Further, we discuss promising directions for future research on the social facilitation of eating.
饮食的社会促进作用（即人们在群体中进食比独自进食时吃得更多）至今已被研究了约三十年。在本文中，我们回顾了关于社会促进作用的实证研究（日记研究、观察性研究和实验性研究），关注增加或减少社会促进性饮食的因素。我们还回顾了针对这种效应所提出的各种解释（例如“时间延长”），并就潜在机制提出我们自己的推测。此外，我们讨论了未来饮食社会促进作用研究的有前景的方向。
