Increased decision thresholds enhance information gathering performance in juvenile Obsessive-Compulsive Disorder (OCD)

摘要: Patients with obsessive-compulsive disorder (OCD) can be described as cautious and hesitant, manifesting an excessive indecisiveness that hinders efficient decision making. However, excess caution in making may also lead to better performance specific situations where the cost of extended deliberation is small. We compared 16 juvenile OCD patients matched healthy controls whilst they performed a sequential information gathering task under different external conditions. found outperformed controls, winning significantly more points. The groups differed number draws required prior committing decision, but not accuracy. A novel Bayesian computational model revealed subjective sampling costs arose non-linear function sampling, closely resembling escalating urgency signal. Group difference was best explained by later emergence these group, evident increased threshold. Our findings present suggest enhanced accounted for higher threshold arising out altered perception that, some contexts, advantageous.
