describe the four problems that can develop if participants from different treatment conditions have an opportunity to talk with each other during the course of the experiment
Homework Answers
The following problems can develop:
1. The treatment effects can spread from treatment groups to
control groups.
2. The control group members may work extra hard to see that
expected superiority of the experimental group is not
demonstrated.
3. The control group may feel demoralized and work less hard.
4. There maybe increased rates of experimental attrition.

Subject bias can occur in an experiment when the participants are aware of the purpose of the study and respond in a way that they think the researchers want. For example, if participants believe they are in a study to test if coffee improves your mood, those who drank coffee might claim to be happier than they really are. Based on the information given, which of the following experiments is most likely to have the issue of a control or...
