In attempting to understand bystander intervention -- why people may or may not intervene as a bystander to an emergency situation in a public place with an innocent victim, we could:
1. put forward ideas as we did last week

In attempting to understand bystander intervention -- why people may or may not intervene as a bystander to an emergency situation in a public place with an innocent victim, we could:
1.put forward ideas as we did last week
2.ask other people for their ideas
3.analyze why we intervened or did not when we had been a bystander to such an emergency situation

In attempting to understand bystander intervention -- why people may or may not intervene as a bystander to an emergency situation in a public place with an innocent victim, we could:
1. put forward ideas as we did last week
2.ask other people for their ideas
3.analyze why we intervened or did not when we had been a bystander to such an emergency situation
4.ask others why they had intervened or not when they had witnessed an emergency situation

In attempting to understand bystander intervention -- why people may or may not intervene as a bystander to an emergency situation in a public place with an innocent victim, we could:
5.ask people who have intervened in an emergency about themselves and about the circumstances and compare their responses to individuals who had not intervened when they had witnessed an emergency
![Page 6: In attempting to understand bystander intervention -- why people may or may not intervene as a bystander to an emergency situation in a public place with.](https://reader036.fdocuments.us/reader036/viewer/2022062321/56649e685503460f94b64345/html5/thumbnails/6.jpg)

In attempting to understand bystander intervention -- why people may or may not intervene as a bystander to an emergency situation in a public place with an innocent victim, we could:
5.ask people who have intervened in an emergency about themselves and about the circumstances and compare their responses to individuals who had not intervened when they had witnessed an emergency
6.analyze public records concerning bystanders who had intervened
7.stage an emergency and record whether people help or not
![Page 8: In attempting to understand bystander intervention -- why people may or may not intervene as a bystander to an emergency situation in a public place with.](https://reader036.fdocuments.us/reader036/viewer/2022062321/56649e685503460f94b64345/html5/thumbnails/8.jpg)
8. stage an emergency and systematically manipulate some aspect of the circumstances or of the nature of the bystanders
that is, have different levels of that circumstance or of the nature of the bystanders.
![Page 9: In attempting to understand bystander intervention -- why people may or may not intervene as a bystander to an emergency situation in a public place with.](https://reader036.fdocuments.us/reader036/viewer/2022062321/56649e685503460f94b64345/html5/thumbnails/9.jpg)
As we will see, one major advantage of this approach addresses
The question of alternative interpretations and certainty about any interpretation.
![Page 10: In attempting to understand bystander intervention -- why people may or may not intervene as a bystander to an emergency situation in a public place with.](https://reader036.fdocuments.us/reader036/viewer/2022062321/56649e685503460f94b64345/html5/thumbnails/10.jpg)
We will want to understand the basic concepts of these methods?
Independent and dependent variables.
Random assignment concerning the levels of the independent variable.
Situational independent variables and individual difference independent variables.
Generating correlational data and experimental data. Inferring a causal relation between two variables. Generalizing to other populations of research participants or to other situations. Debriefing session in laboratory experiments.

Research Methods in Social Psychology
1.Laboratory experiment: e,g, Darley and Latane's study concerning size of group related to bystander intervention. Conducted in their laboratory with a staged emergency involving a confederate (apparent epileptic seizure).

Situational Independent Variables
Individual Difference Independent Variables
Some dimension on which people vary that can be measured – they vary on this dimension prior to coming to participate in your study.
![Page 22: In attempting to understand bystander intervention -- why people may or may not intervene as a bystander to an emergency situation in a public place with.](https://reader036.fdocuments.us/reader036/viewer/2022062321/56649e685503460f94b64345/html5/thumbnails/22.jpg)

Compute a correlation coefficient,designated as r
![Page 23: In attempting to understand bystander intervention -- why people may or may not intervene as a bystander to an emergency situation in a public place with.](https://reader036.fdocuments.us/reader036/viewer/2022062321/56649e685503460f94b64345/html5/thumbnails/23.jpg)
For example, the computed correlation coefficient between trait social responsibility and speed of helping could approach +1.00, or -1.00, or could approach 0.00.
This would indicate, respectively,
a high positive association between the two variables,
or a high negative association,
or the lack of any association.

Carnegie Hero Medal Recipient
Hannah Goorsky rescued Chad Summers from an attacking tiger, Sacramento, California, March 23, 2003. While attempting to close the door to a den of the tiger cage at the zoo where he was employed, Summer, 30, was attacked by a 320-pound tiger that had rushed the door. Wounded, he went to the floor, where the tiger began to maul him. Starting her third day as a volunteer at the zoo, Ms. Goorsky, 23, was standing nearby and witnessed the attack. She grabbed a shovel, approached the tiger, and struck it on the head repeatedly with the shovel. The tiger retreated into its den, Ms. Goorsky securing the door. Summers was hospitalized for treatment of numerous bite wounds.

The question of correlational data or experimental data in this example

Points to be Careful About
1.Make certain that you have two independent variables in your proposed study (with two levels of each variable).
2.Remember, your individual difference variable concerns some dimension on which people vary prior to coming to your study to witness an emergency.
3.We strongly encourage you to use the building A to B procedure. Among other advantages, this will allow you to control for your individual difference independent variable. Remember, this involves elements of both a field and a lab experiment.
4You may have both experimental data and correlational data in your study (depending on the nature of your individual difference variable).

5. You are encouraged with your individual difference independent variable to generate experimental data, if possible.
6. Randomly assign (but not randomly select).
7. You have all the resources you need, within reason, to conduct the study (but, of course, you will not be carrying it out).
8. You will not lose marks for not being original; you may gain marks for being original.
9. Follow the guide to the writeup. Even if you worked with others, you must submit your own paper (and put the
names of the others on the front page).
