The concept of social facilitation is so named because of the idea that when the presence of others is arousing, "this arousal facilitates a well-learned, dominant response".
<h3>What is
social facilitation?</h3>
The tendency for the presence of others to enhance a person's performance on a task is known as social facilitation.
Two types of social facilitation have also been defined: co-action effects and audience effects:
- A co-action effect: is when your performance on a task improves simply because there are other people performing the same job as you. As an illustration, consider working alongside coworkers in an office setting as opposed to by yourself.
- Audience effects: An audience effect is when your performance improves as a result of performing in front of a crowd. A pianist playing at home as opposed to performing in front of an audience is an example.
In addition, three more components are believed to play a role in social facilitation:
- physiological (drive and arousal),
- cognitive (distraction and attention), and
- affective (emotional) factors (anxiety and self-presentation).
