Experiment 2 accuracy. Each block includes 25 trials. Top Panel: Accuracy in the Relearning and Meta-Learning conditions throughout the entire experiment. Blocks 1–12 were in the acquisition phase, blocks 13–24 were in the intervention phase, and blocks 25–36 were in the reacquisition phase. Middle Panel: Overlaid accuracy data in the Relearning condition from the acquisition phase, intervention phase, and reacquisition phase. Bottom Panel: Overlaid accuracy data in the Meta-Learning condition from the acquisition phase, intervention phase, and reacquisition phase.
