Dopaminergic D1 Receptor Stimulation Affects Effort and Risk Preferences

Background Activation of D1 receptors has been related to successful goal-directed behavior, but it remains unclear whether D1 receptor activation causally tips the balance of weighing costs and benefits in humans. Here, we tested the impact of pharmacologically stimulated D1 receptors on sensitivity to risk, delay, and effort costs in economic choice and investigated whether D1 receptor stimulation would bias preferences toward options with...
