Abstract

Support for a neurobiological distinction between affiliation (Attachment) and agency (Achievement) was achieved by comparing responses to a dopaminergic (DA) and a serotonergic (5-HT) challenge test. DA responses were similar, but a 5-HT modulation of DA emerged for Achievement and not for Attachment. Molecular genetics performed on Panksepp’s dimension “Care” revealed an association with a polymorphism of the DA catabolizing enzyme COMT that was not associated with separation distress.
