This study shows that dopamine enhances model-free credit assignment by boosting retrospective model-based inference, with effects linked to working memory and a trade-off with model-based credit assignment.

This study investigates how baseline dopamine levels influence the effect of L-DOPA on model-based and model-free control in decision-making tasks.

This study shows that L-DOPA reduces model-free control of behavior by decreasing the influence of reward on choices and increasing choice randomness, as measured by fMRI.
