http://faculty.babson.edu/krollag/org_site/soc_psych/latane_bystand.html Method Participants The subjects where all university students of various genders
who were placed in different size groups using random sampling. Materials In the smoke room experiment, the subjects were placed in a room on chiars, with a smoke machine in the air vent to emmit smoke for 6 minutes until the room was filled with a smokey haze. the second experiment had cubicals set up for one person with microphones in each. Procedure: Experiment One Procedure: Experiment Two Students are invited to fill out a questionnaire
When they arrived the students were asked to sit in a room, either by themselves or in a gorup of four.
Smoke begins to fill the room.
Smoke filled the room until it was full for six minutes.
Record how many students go for help. Students placed in cubicles to have a discussion.
Students are told that they are in a group of two (themselves and one other), a group of four, or a group of six. All in their own cubicals with microphones.
One student tells the others that he is an epileptic.
The "epileptic" student makes choking and gasping noises, pretending to have an epileptic fit.
Record how many students went for help. Abstract Ethical Principles Deception was the main ethical principle involved.
the participants were not alloud to know the true
nature of the experiment otherwise the results could of been jeopardised. but debriefing needed to happen after the experiments where conducted. however during deception, the participants should not be exposed to psychological stress, such as that of hearing someone potentially be dying. Results Two People Four people six people Experiment one: Smoke Room Experiment two: Epileptic Fit In the smoke room experiment, the results show that if the participants were alone, 75% would go and get help after smoke filled the room. if there were more people in the room while the smoke filled the room, only 35% went to get help. In the second experiment with cubicles, when alone except for the 'epiletic', 85% of people went for help. When the participant thought that there was four people in total, 65% went for help, but when the participants beleived that there was six other people in the cubicles, only 35% were able to go for help. Discussion The hypothesis was accepted after the results had been studied. the results from both the smoke room experiment and the Epileptic fit experiment showed that the larger the group, the likelyhood of people going to get assistance was reduced significantly. This information is consistant with other reasearch into the bystander effect, and strengthens the argument that in larger groups, deminished responsibility can cause people not to act. Extranueous Variables: Two Possible extraneous variables in these two experiments could be the fact that different aspects came into play during the experiment other than just the feeling of deminished responsibility, such as the mood of the participants when they go into the study, or if the tst subjects feel incompotent and therefore doesnt wat to try and help in case of failure. Generalisation: In conclusion, the results show that when in large groups, a person is less likely to offer help to someone in need, or help in an emergancy situation, based on the belief that smeone else could do it. So if you decide to have a heart attack, it is better to have one in a street with almost no people than in a crowded city street, because no one will help you.
