Figure 3

Feedback-based flexibility paradigm. Participants either perform the odd/even judgment task or the </>5 task (see Figure 1). Participants need to learn the current rule based on the visual feedback they receive after each trial, and have to adjust their behavior after rule reversals. Probabilistic errors are not shown in the schematic, but involve a negative feedback without an actual task reversal, and serve to increase the unpredictability of task reversals. The dark hand indicates the participant’s button press, while the arrow points toward the correct hand (i.e., rule) to use.
