当他们的饮食同盟吃得很多时，人们会吃得更多。然而，目前还不清楚参与者的饮食是否会被远程视频联盟改变。我们比较了三种类型的无声视频：1）陌生人吃薯片，2）陌生人打电话，3）只有物体（食物和手机）。参与者只有在观看别人吃爆米花的视频时才觉得爆米花更好吃。观看其他人吃东西会诱导参与者比观看其他两个视频时吃得更多。这项研究表明，远程视频联盟不仅提高食物的摄入量，但也感知食物的味道。
People eat more when their eating confederates eat a lot. However, it was not clear whether participants' eating is changed by a remote-video confederate. We compared three types of silent videos: 1) a stranger eating potato chips, 2) the stranger calling on the phone, or 3) only objects (food and cellphone). Participants perceived popcorn to taste better only when they watched the video of others eating. Watching others eating induced the participants to eat more than when watching the other two videos. This study indicates that remote-video confederates enhance not only food intake but also the perceived taste of food.
