Social facilitation is a widespread phenomenon in society. Many public tasks demonstrate the effects, both the costs and benefits, of social facilitation. From taking exams in a high school or college environment to performing in sporting events, people may perform better or fall short depending on the task's complexity. In many experiments, people display signs of social facilitation even in everyday tasks, such as driving. This effect can even be seen in animals, as displayed by Zajonc, Heingarter, and Herman's study on cockroaches.
