Psychology I / Group Dynamics: Polarization, Groupthink, and Performance
Practice question · Multiple choice

Social loafing and social facilitation both concern what the presence of others does to performance - and they predict opposite effects. What determines which one occurs?

Hints
  1. In one case you are being watched. In the other you are hidden in a total. Which is which?
  2. A rope-pulling experiment where each person's force is measured separately: what happens?
Show the answer

D. Whether individual contributions can be identified.

Why

The two describe different relationships to an audience: facilitation is about being observed and evaluated, which is Yerkes–Dodson in a social setting; loafing is about being unobservable. Ringelmann's rope produces loafing, and measuring each person's pull separately with the same eight people largely abolishes it. Identifiability is the switch.
