Violet is trick-or-treating on Halloween night, all decked out in her Despicable Me "Agnes" costume. At each house she politely takes one piece of candy from the bowl, as she knows to do. Later in the evening she puts on her "Agnes" mask and continues to make the rounds in the neighborhood. Now, when faced with a bowl of candy, she sneaks four or five pieces into her bag. What contributed to Violet's change in behavior?
◦ Social loafing; she found it easier to take more candy from each house than to follow the group norm.
◦ Her choice of costume; a werewolf or other monster mask would have sparked a norm of cooperation.
◦ Groupthink; the absence of an impartial trick-or-treat leader led to deviant behavior.
◦ Deindividuation; by wearing the mask she lost her personal identity and relinquished her individual norms for correct behavior in this situation.
