Dan really doesn't feel like riding the stationary bicycle today, but he doesn't want the people around him to think he is a slacker. If he decides to continue exercising, what concept might explain his actions?

A) social productivity
B) social loafing
C) social facilitation
D) social idleness

Social facilitation refers to the phenomenon where the presence of others increases arousal and improves performance on simple or well-learned tasks, but can decrease performance on complex or new tasks. In this scenario, Dan's desire to not appear lazy in front of others may be increasing his arousal and improving his performance on the stationary bicycle.
