Guilt in decision making. The effect of guilt emotion on how a decision maker focuses on a problem was investigated in the January 2007 issue of the Journal of Behavioral Decision Making (see Exercise 3.48, p. 177). A total of 171 volunteer students participated in the experiment, where each was randomly assigned to one of three emotional states (guilt, anger, or neutral) through a reading/writing task. Immediately after the task, students were presented with a decision problem where the stated option had predominantly negative features (e.g., spending money on repairing a very old car). The results (number responding in each category) are summarized in the accompanying table. Is there sufficient evidence (at a = .10) to claim that the option choice depended on emotional state? Use the data saved to answer the question. Emotional State Choose Stated Option Do Not Choose Stated Option Totals Guilt 45 12 57 Anger 8 50 58 Neutral 7 49 56 Totals 60 111 171 Source: A.
