Effects of social facilitation on individual
Tharp, E. The research regarding modeling is not as well developed as that for eating in groups, and it has much larger gaps. The positive correlation could result from a covariation produced by a third factor, the time of day.

Drive theory of social facilitation
Triplett's study started off a revolution of studies attempting to examine the theory that people's performance is influenced by the presence of others. However, either behavioral or physiological compensation for the lowered intake may occur over time, reducing the effectiveness of the eating alone manipulation. Indeed, the diet diary data indicate that the duration and not the rate of intake increases when meals are eaten socially de Castro, ; de Castro and Brewer, ; see Figure However—and this is something we did not make a lot of—it all practically increased dessert consumption. Nisbett and Storms invited subjects to eat crackers in a taste test. Jacobson, O. Seasonal rhythms of human nutrient intake and meal patterns. In the laboratory, subjects, regardless of gender, ate 94 percent more ice cream in groups than when eating alone Berry et al. Hence, not only are meals eaten with other people larger than meals eaten alone, but the greater the number of people present, the more that is ingested. Frank demonstrated that subjects would eat simply in response to an instruction to eat, even when told that they were participating in an experiment on persuasion and that it did not matter whether they ate or not. Stewart, P.
Age related changes in natural spontaneous fluid ingestion and thirst in human. This indicates that the other factors, such as cognitive variables and players' interpretation of the audience's presence, also influence players' reactions to the presence of an audience in a natural setting.
He found that children performed much better while they were competing with one another, and further research led Triplett to theorize that the presence of others increases individuals' performances in other noncompetitive situations as well. McCormick, M. This topic is of substantial interest to those in the field of social psychology due to underlying mechanism at work; namely, the phenomenon of social facilitation. He designed an experiment that would examine the performance of someone doing a simple vs. This hypothesis predicts that self-rated hunger would be higher at the beginning of socially facilitated meals but should be about the same at the end. Coward, A. The mere presence of another is not enough. Other co-action effect studies include Chen who observed that worker ants will dig more than three times as much sand per ant when working non-co-operatively alongside other ants than when working alone and Platt, Yaksh and Darby found that animals will eat more of their food if there are others of their species present. The generalized drive hypothesis was the first theory that addressed both increase and decrease in performance of people in the presence of others. Morris, P. In , while studying the competitive nature of children,  he found that children were much faster at completing their given activity winding string while they were competing, which caused him to wonder whether or not simply having another individual there would have the same effect. Hence, in the laboratory, the food intake of a subject can be profoundly influenced by the food intake of a companion even when the subject is extremely hungry. In addition, the correlation was equivalent even when meals eaten alone were excluded.
We got no effects at all, no enhancement. Results for the analyses of the duration and rate of intake with differing numbers of people present are presented in Figure It was concluded that the presence of others is a sufficient condition for social facilitation and social interference effects.
The research also suggests that eating in groups would only be of benefit when the soldiers have time available to extend the duration of meals.
Social facilitation theory
Soldiers in the field under-ingest nutrients, and social facilitation may be useful in promoting greater food intake. In fact, the meal sizes reported during the manipulated alone condition were 20 percent larger than the alone meals during the normal condition Redd and de Castro, Most human behavior is shaped or controlled by social forces. Still another possibility is that meals eaten on weekends may be larger and eaten with more other people present than are meals eaten on weekdays. The activation theory describes how our arousal relates to social facilitation. It was concluded that the presence of others is a sufficient condition for social facilitation and social interference effects. Another potential explanation for social facilitation is that the presence of other people may increase perceived hunger Tolman, The evaluation theory discusses how being assessed by an audience affects to social facilitation. Their task was to wind in a given amount of fishing line and Triplett reports that many children worked faster in the presence of a partner doing the same task. Social facilitation of the spontaneous meal size of humans is independent of time, place, alcohol, or snacks. Wack, G. Perhaps the first social psychology laboratory experiment was undertaken in this area by Norman Triplett in In these situations the presence of others may help by narrowing the focus of attention.
