目的：人们通常认为，人们吃得过多，他们喜欢的食物。我们调查了诸如包装和容器大小等环境线索是否如此强大，以至于它们可以增加我们对不太可口的食物的摄入量。设计，设置和参与者：在一个2 x 2的受试者间设计中，费城的158名电影观众（57.6%男性; 28.7岁）被随机给予一个中型（120克）或大型（240克）容器的免费爆米花，无论是新鲜的或陈旧的（14天）。以下的电影，消费措施，沿着与措施的感知taste.Outcome措施和结果：电影观众谁得到新鲜爆米花吃了45.3%的爆米花时，它给他们在大容器。这种容器大小的影响是如此强大，即使当爆米花是不喜欢的，人们仍然吃了33.6%以上的爆米花时，从一个大的容器比从一个中型container.Conclusions和影响：即使当食物不可口，大包装和容器可以导致暴饮暴食。这些发现的银衬可能是，部分大小也可以用来增加不太喜欢的健康食品的消费，如生蔬菜。
Objective: It is often believed that people overeat the foods they like. We investigated whether environmental cues such as packaging and container size are so powerful that they can increase our intake of foods that are less palatable.Design, Setting, and Participants: In a 2 x 2 between-subjects design, 158 moviegoers in Philadelphia (57.6% male; 28.7 years) were randomly given a medium (120 g) or a large (240 g) container of free popcorn that was either fresh or stale (14 days old). Following the movie, consumption measures were taken, along with measures of perceived taste.Outcome Measures and Results: Moviegoers who were given fresh popcorn ate 45.3% more popcorn when it was given to them in large containers. This container-size influence is so powerful that even when the popcorn was disliked, people still ate 33.6% more popcorn when eating from a large container than from a medium-size container.Conclusions and Implications: Even when foods are not palatable, large packages and containers can lead to overeating. The silver lining of these findings may be that portion size can also be used to increase the consumption of less preferred healthful foods, such as raw vegetables.
