1. A researcher is interested in the effects of ambiguity and number of bystanders on helping behavior. Each participant fills out a questionnaire in a room by themselves or with two other people (confederates) who appear to be other participants. The experimenter distributes the questionnaire and then goes into the room next door. After 5 minutes, there is a loud crash. For half of the participants, the experimenter unambiguously calls out that he has fallen, is hurt, and needs help. For the remaining participants, the situation is more ambiguous –the experimenter says nothing. Twenty participants are tested in each condition, and the experimenter records how long it takes (in seconds) before the participant offers help. (Confederates do not respond to the noise.)
0 bystanders, ambiguous: 24s
2 bystanders, ambiguous: 38s
0 bystanders, unambiguous: 14s
2 bystanders, unambiguous: 14s
