Answer:
The improved performance on simple or well-learned tasks in the presence of others is known as social facilitation.
Step-by-step explanation:
This phenomenon refers to the tendency for individuals to perform better on tasks when they are in the presence of others, compared to when they are alone. Social facilitation can occur even when the presence of others is passive, such as simply having an audience, and is most likely to happen when individuals are performing tasks that they are already proficient at or that are relatively simple. However, social facilitation can also have negative effects on performance for tasks that are more complex or unfamiliar to the individual.
