Increased decision thresholds enhance information gathering performance in juvenile Obsessive-Compulsive Disorder (OCD)
Fig 3
Choice probabilities (policy π) of the winning model.
For each stage of a game (x axis), the model predicts the average probability of choosing yellow colour (Py), blue colour (Pb), or continuing to sample (pink, PND). For the fixed condition (top), OCD patients (right) are more likely to continue sampling in conditions where the majority is not clearly apparent. In the decreasing condition (bottom), the probability of not deciding is lower than in the fixed condition in both groups (less pinkish colours). It is also noteworthy that OCD adolescents flexibly adapt their strategy in the decreasing condition, indicating against a general inflexibility in OCD.
