Decision-making during mixed-strategy games requires flexibly adapting choice strategies in response to others’ actions and dynamically tracking outcomes. Such decisions involve diverse cognitive processes, including reinforcement learning, which are affected by disruptions to the striatal dopamine system. We therefore investigated how genetic variation in dopamine function affected mixed-strategy decision-making in Parkinson’s disease (PD), which involves striatal dopamine pathology.
