Variants at serotonin transporter and 2A receptor genes predict cooperative behavior differentially according to presence of punishment.

Proceedings of the National Academy of Sciences of the United States of America - 5 Mar 2013

Schroeder Kari B, McElreath Richard, Nettle Daniel

Abstract excerpt

Punishment of free-riding has been implicated in the evolution of cooperation in humans, and yet mechanisms for punishment avoidance remain largely uninvestigated. Individual variation in these mechanisms may stem from variation in the serotonergic system, which modulates processing of aversive stimuli. Functional serotonin gene variants have been associated with variation in the processing of aversive stimuli...
