Explanation:

According to my research on different research components, I can say that based on the information provided within the question in this example the dependent variable is the researcher's reaction to the subjects test results. This is because the point of the research study is to prove that a person's mood has an effect on how helpful that person is likely to be. Since the person's mood in this situation is completely dependent on whether the researcher praises or criticizes the subject then we can say that is the dependent variable.
