Le Bon's theory,convergence theory,and emergent-norm theory are all theories of

A) social facilitation.
B) deindividuation.
C) crowd behavior.
D) group performance.
E) group entitativity.

Le Bon's theory, convergence theory, and emergent-norm theory all attempt to explain different aspects of crowd behavior. Le Bon's theory suggests that individuals lose their sense of individuality and become more suggestible in a crowd. Convergence theory focuses on how like-minded individuals come together in a crowd and reinforce each other's beliefs and behaviors. Emergent-norm theory suggests that crowds can develop their own norms and values that differ from those of individuals in isolation. Therefore, the correct choice is C - crowd behavior.
