The presence of other people will increase performance for:

A) Alisha on her first day on the job,when learning a task in front of her team.
B) Tom,who is washing his bike in front of his neighbors.
C) Lola Bea,who is learning new dance moves as her team watches.
D) Alan,who is learning a difficult basketball maneuver with his team.

The presence of other people tends to increase performance on tasks that are simple or well-learned, as in the case of Tom washing his bike, which is likely a task he is familiar with. This phenomenon is explained by social facilitation theory. For tasks that are complex or new, as in the cases of Alisha, Lola Bea, and Alan, the presence of others can actually hinder performance due to increased anxiety or pressure.
