Reаd the fоllоwing pаssаge and determine the authоr’s topic. Passage C The participants were male college students. Each student, placed in a room by himself with an intercom, was led to believe that he was communicating with one or more students in an adjacent room. During the course of a discussion about personal problems, he heard what sounded like one of the other students having an epileptic seizure and gasping for help. During the “seizure,” it was impossible for the participant to talk to the other students or to find out what, if anything, they were doing about the emergency. The dependent variable was the speed with which the participant reported the emergency to the experimenter. The likelihood of intervention depended on the number of bystanders the participant thought were present. The more people he thought were present, the slower he was in reporting the seizure, if he did so at all. Everyone in a two-person situation intervened within 160 seconds, but nearly 40 percent of those who believed they were part of a larger group never bothered to inform the experimenter that another student was seriously ill.
