Answer to Question 1

If participants in a no-treatment condition talk with participants in a treatment condition they may learn about the treatment and adopt some of the treatment components. This leads to diffusion of treatment. If participants in an inferior condition learn about a superior treatment being received by others, they may demand equal treatment (compensatory equalization), they may become extra motivated to make up for the inferior treatment (compensatory rivalry), or they may give up in the face of a hopeless situation (resentful demoralization).
