The effect of guilt emotion on how a decision maker focuses on a problem was investi- gated in the Jan. 2007 issue of the Journal of Behavioral Decision Making (see Exercise 1.32, p. 28). 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 pre- dominantly negative features (e.g., spending money on repairing a very old car).
