The term for an improvement in performance caused by the perception that others are watching is social facilitation. This phenomenon occurs when the presence of others enhances our arousal and attention, leading to improved performance on simple or well-learned tasks. On the other hand, for complex or novel tasks, the presence of others can lead to social inhibition, or a decrease in performance. Social loafing refers to a reduction in effort or motivation when individuals work in a group or team, while social idleness is not a recognized psychological term. Social productivity is a term that is sometimes used to describe the effectiveness and collaboration of a group or team.
