Study Summary
The investigators are examining whether conditions of ambiguity during decision-making may prime intolerance of uncertainty beliefs (i.e., difficulties coping with ambiguity, unpredictability, and the future) and lead to impaired performance when individuals with obsessive-compulsive disorder (OCD) are making uncertain decisions compared to non-psychiatric controls.
Primary Outcome
In the Risk and Ambiguity Task participants make repeated choices between a certain payoff vs. a gamble. On low ambiguity trials, the likelihood of the gamble is known (i.e., "risky" lottery). On high ambiguity trials, the likelihood of the gamble is unknown (i.e., "ambiguous" lottery). Ambiguity aversion = (number of 50% risky lotteries chosen / total number of 50% risky lotteries) - (# of ambiguous lotteries chosen / total number of ambiguous lotteries).
