Which term relates to individuals performing better in a group setting than they would individually?

The correct term that describes individuals performing better in a group setting than they would individually is social facilitation. This phenomenon occurs when the presence of others enhances an individual's performance on tasks, particularly those that are simple or well-practiced. In a group environment, the awareness of being observed by peers can motivate individuals to elevate their performance due to increased arousal and competition.

Social loafing, on the other hand, refers to the tendency of individuals to exert less effort when working in a group compared to when working alone. This is the opposite effect of social facilitation. Group polarization involves a situation where discussions within a group lead to more extreme positions than those held individually, influencing decision-making rather than performance levels. Collective efficacy relates to a group's shared belief in its ability to succeed, which can be crucial for motivation and performance but does not directly describe the performance enhancement seen in social facilitation. Thus, social facilitation is the most accurate term for the scenario presented.
