Design a study of the effects on people's self esteem of engaging in helping behavior. To do that you need to create a situation in the lab in which everyone will help your confederate. Using what we know about the effect of Mood on helping behavior, Social Norms that influence helping behavior, the effects of models on helping behavior, and what we know about who gets helped, describe 3 things you would do in the situation you create that would increase the likelihood that helping behavior would occur. {Note: a good answer will include for each of the three things an explanation of which category your ploy comes out of, what we know about how that item works, and how you would use it. For example: if using mood, what is the mood, how does it influence helping, and how will you create or eliminate that mood in your participant?
