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.
