Subjects performed a classification learning task with two different problems (across different runs), using a "weather prediction" task. In one (probabilistic) problem, the labels were probabilistically related to each set of cards. In another (deterministic) problem, the labels were deterministically related to each set of cards. After learning, subjects participated in an event-related block of judgment only (no feedback) in which they were presented with stimuli from both of the training problems.
Note (30 Jan 2016): It was reported that the anatomical volumes for subjects sub016 and sub017 are identical. Updated data downloads will be available soon.
Note (22 Feb 2016): In addition to the above note, it was found that some subjects highres001 and inplane data did not seem to be from the same person. We advise using this dataset with caution until these issues are corrected.
