Payton and his friends all go to his school's basketball game wearing matching team shirts, and they sit together in a group. when his friends start cursing at supporters from the other college, payton starts cursing too because he feels like he is part of a group, even though normally payton is very conscientious and seldom yells at anyone. payton's yelling is an example of: deindividuation. social loafing. groupthink. obedience.

The correct answer is deindividuation. 

Deindividuation refers to the phenomenon in which belonging to a group makes individual memebers lose their self-awareness and sense of personal responsibility. Individuals belonging to a group get "swept up" in the group's activities and collective behavior, which in turn leads them to behave in a manner that is uncharacteristic and not typical of their general behaviors and values. Payton's yelling and cursing appears to result from deindividuation.
