Social facilitation is a psychological phenomenon where an individual's performance on a task improves in the presence of others. This effect is often observed in simple or well-practiced tasks, where the presence of an audience can enhance motivation and focus, leading to better outcomes. Conversely, social facilitation can also lead to decreased performance on complex or unfamiliar tasks. When individuals feel anxious or self-conscious in front of others, it may hinder their ability to perform well. This dual effect highlights the influence of social environments on individual behavior and performance.
