Guilt in decision making. The effect of guilt emotion on how a decision maker focuses on the problem was investigated in the Jan. 2007 issue of the Journal of Behavioral Decision Making . 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, the students were presented with a decision problem where the stated option has 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 and saved in the GUILT file. Is there sufficient evidence (at α = .10) to claim that the option choice depends on emotional state?
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 |
