Question: 1. Common sense says that a valuable goal is worth suffering for. Is that the way it works? In a classic experiment in social psychology (Aronson and Mills, 1959), college women had to "qualify" to be in an experiment. The qualification activity caused severe embarrassment, mild embarrassment, or no embarrassment. After qualifying, the women listened to a recorded discussion, which was, according to the experimenters, "one of the most worthless and uninteresting discussions imaginable." The dependent variable was the women's rating of the discussion. Analyze the ratings using the techniques in this chapter (high scores favorable ratings). Write an interpretation.
