Title: Neuromodulation of moral decision-making

 

Abstract: 

How we evaluate the suffering of others is a central concern in moral decision- making, but its neural basis is unknown. Here, we ask how people value others’ pain relative to their own pain, and how serotonin and dopamine influence aversion to pain for self and others. To investigate these questions, we observed people trading off profits for themselves against pain for themselves or an anonymous other person, and used computational models to quantify how they valued others’ pain relative to their own pain. In two behavioral studies, we show that most people selflessly sacrifice more money to prevent others’ pain than their own pain. In two subsequent pharmacological studies, we examined the effects of the serotonin reuptake inhibitor citalopram and the dopamine precursor levodopa on the valuation of pain for self and others. Citalopram and levodopa had distinct and opposing effects on moral decision-making. Our findings have implications for understanding antisocial behavior in psychiatric disorders associated with abnormal serotonergic and dopaminergic function.
