The agency facet of extraversion (aE) describes individual differences in goal-directed behavior and has been linked to dopamine function in incentive contexts. Because dopamine presumably modulates the processing of negative feedback/failure, aE may relate to failure processing in incentive contexts. To test this hypothesis, N = 86 participants performed a(More)
Consistent with dopamine accounts of internal and external feedback processing, prior work showed that the dopamine D2 receptor antagonist sulpiride modulates the relationship between the dopaminergic COMT Val158Met polymorphism and the error-related negativity (ERN). Here, we tested in an independent sample whether this Gene × Substance interaction(More)
The emotion 'warmth-liking' (WL) associated with feelings of affection and acceptance is regularly activated in social contexts. WL has been suggested to be more closely related to the consummatory phase of post-goal attainment positive affect than to pre-goal attainment positive affect/approach motivation and to be partly mediated by brain opioids. To(More)
Neurobiological research suggests there are discrete emotion systems, which are based on separate neural pathways with specific neurotransmitters (i.e., oxytocin, opioids). So far, autonomic regulation patterns of different positive emotions could not be unambiguously characterized. Warmth-liking, as an emotion system, is activated during interpersonal(More)
