Latané and Darley's study
1. As part of a course credit, 72 students (59 female and 13 male) participated in the experiment
2. They were asked to discuss what kind of personal problems new college students could have in an urban area
3. Each participant sat in a booth alone with a pair of headphones and a microphone
4. They were told that the discussion took place via an intercom to protect the anonymity of participants
5. At one point in the experiment a participant (a confederate) staged a seizure
6. The independent variable (IV) of the study was the number of persons (bystanders) that the participant thought listened to the same discussion
7. The dependant variable (DV) was the time it took for the participant to react from the start of the victim's fit until the participant contacted the experimenter
