Eating in groups. Some research has shown that people eat more when they eat in groups. One possible mechanism for this phenomenon is that they may spend more time eating when in a larger group. A study designed to examine this idea measured the length of time spent (in minutes) eating lunch in different settings.4 Here are some data from this study:
| Number of people eating | ||||||
|---|---|---|---|---|---|---|
| Lunch setting | 1 | 2 | 3 | 4 | 5 or more | Mean |
| Workplace | 12.6 | 23.0 | 33.0 | 41.1 | 44.0 | 30.7 |
| Fas | 10.7 | 18.2 | 18.4 | 19.7 | 21.9 | 17.8 |
| Mean | 11.6 | 20.6 | 25.7 | 30.4 | 32.9 | 24.2 |
