音乐节奏和共餐人数对就餐时间的影响

Effects of Music Tempo and Group Size on Eating Time in College Cafeteria

本实验采用现场实验研究的方法,对不同音乐节奏和共餐人数条件下大学生就餐时间的差异进行了分析。结果表明:(1)总的来说,音乐节奏对就餐时间的主效应是显著的,快节奏音乐下的就餐时间少于慢节奏下的就餐时间;(2)单人组被试就餐时间显著快于多人组被试共餐时间;(3)音乐节奏和共餐人数对就餐时间存在交互作用;(4)在单人就餐时音乐节奏对就餐时间的效应是显著的,而多人共餐则没有这种效应或效应不显著。

The field study was aimed at examining the effects of music tempo and group size on the eating time of college students in the cafeteria. The results showed that 1） music tempo had main effects on eating time; 2） the time spent by the single-person group was remarkably less than that by the multi-person group; 3） music tempo and group size had an interactive influence on eating time, and 4） in the singleperson group, there was a direct link between the tempo of the background music being played and the time the subjects spent——the faster the music tempo, the faster the subjects had their meals, but in the multi-person group, music tempo had no significant effect.
