This study investigates how dopamine levels affect exploration-exploitation behavior in humans, finding that cognitive capacity and sex moderate L-DOPA effects on decision-making.

The paper re-examines the pharmacological effects of L-DOPA on temporal discounting in a large sample and evaluates proxy measures for dopamine, finding a reliable reduction in discount rate with no credible effects from proxy measures.

This study investigates whether dopamine manipulation affects illusory pattern perception in healthy individuals, finding no significant effect of L-DOPA on false alarm rates or other measures.

The paper examines how motor response vigour and eye movements correlate with subjective value during intertemporal choice, finding that higher rewards are discounted less and are associated with stronger responses.

The paper evaluates parameter and model recovery of the Kalman SMEP reinforcement learning model in restless bandit tasks using simulation and Bayesian inference.
