The affiliative playfulness and impulsivity of extraverts may not be dopaminergically mediated
Published online by Cambridge University Press: 01 June 1999
Abstract
A major dopaminergic role for extraversion is compromised by the fact that affiliation and impulsivity tend to be reduced by psychostimulants. Also, the large clinical literature on the treatment of ADHD with drugs that promote dopamine activity provides little or no support for a major role for dopamine in human extraversion. Dopamine facilitation of agency may be more evident for inanimate rather than animate rewards.
