This study investigates how dopamine and opioid receptor antagonism affect neural processing of social and non-social rewards using functional neuroimaging and pharmacological interventions.

This study shows that testosterone reduces strategic prosocial behavior in males when they are being watched, without affecting reinforcement learning itself.

This study investigates how dopamine D2 and opioid receptor antagonism affects the balance between model-based and model-free behavior in healthy volunteers, finding that D2 antagonism increases model-based behavior while opioid antagonism has no significant effect.

This study shows that blocking D2/D3 dopamine receptors increases belief volatility during trust learning, particularly in individuals with higher dopamine availability.

This study shows estradiol increases reward sensitivity in men, with effects moderated by baseline dopamine levels.

This study investigates the neurochemical basis of hedonic facial reactions to social and nonsocial rewards by manipulating dopaminergic and opioidergic systems in humans.
