Research shows that many small changes to the environment impact one's eating behavior. The aim of this study was to examine whether the type of audio transmission would affect snack intake depending on the degree of immersion. A sample of 174 university students were randomized to either viewing a movie wearing headphones or listening over loud speakers while consuming a snack of their choice. Significant differences were found with more snacks consumed in the group without headphones compared to the group wearing headphones. Particularly women tend to eat less (about 10% of the offered snack less) when wearing headphones while viewing a movie. The results seem to indicate that audio transmission mode might impact eating behavior.
研究表明，环境中的许多小变化都会影响人的饮食习惯。本研究旨在探讨音频传输类型是否会根据沉浸度的不同影响零食摄入量。随机抽取了 174 名大学生，让他们在选择的零食时，要么戴耳机看电影，要么通过扬声器听电影。结果发现，戴耳机组比不戴耳机组吃的零食更多。特别是女性在戴耳机看电影时吃得更少（大约少 10%提供的零食）。结果似乎表明，音频传输模式可能会影响饮食行为。
