When Does Model-Based Control Pay Off?
Fig 16
Behavioral performance on the two-step tasks.
(A) Behavioral performance on the Daw task showed both a main effect of previous outcome and an interaction between previous outcome and transition type, suggesting that behavior showed both model-based and model-free strategies. (B) Behavioral performance on the novel paradigm showed a significant difference in stay behavior between same and different start states conditions after a reward, suggesting that behavior was not fully model-based. Error bars indicate within-subject SEM.
