Scenario C: Julian is walking down a busy street when he sees a man lying on the ground. Several people are standing around the man, but no one seems concerned about him. Several other people continue walking by after glancing at the man.

  1. According to the bystander effect, is Julian likely to help the man? Why or why not?
  2. How will the concept of pluralistic ignorance influence Julian’s behavior? Be sure to discuss Julian’s assessment of how other people are interpreting the situation.
  3. How does the concept of diffusion of responsibility apply to this situation and how will it impact Julian’s helping behavior? How would it change things is Julian was the only one around to see the man?
  4. Based on information from your textbook, list at least three reasons why Julian might decide not to intervene even if he has made it to the last step of Latané and Darley’s five steps to helping in an emergency (i.e., the “deciding to implement help” step).
  5. What two forms of media have been shown to increase prosocial behavior? List the two ways that prosocial media is thought to increase cooperation and helping?
  6. Describe a research study presented in your book that supports the conclusion that Julian would be more likely to help the man if he had previously learned about the bystander effect.
