| Extraversion: Extraversion is one of the Big Five personality traits in psychology. It reflects outgoing, social, and energetic tendencies. Extraverts typically enjoy social interactions, and often exhibit assertiveness and enthusiasm. See also Personality traits, Openness, Agreeableness, Conscientiousness, Neuroticism. _____________Annotation: The above characterizations of concepts are neither definitions nor exhausting presentations of problems related to them.

Molecular Genetics on Extraversion - Dictionary of Arguments
Corr I 294 Extraversion/motivation/molecular genetics/Munafò: The dopaminergic system is involved in appetitive and motivational behaviours (Comings and Blum 2000)(1), and pharmacological challenge studies indicate a relationship between dopaminergic hyperactivity and reward-seeking, as well as motivational factors associated with both Extraversion and novelty-seeking (Netter 2006)(2), suggesting that these traits may share a common neurobiological basis. The dopamine D4 receptor (DRD4) gene is highly polymorphic, although research evaluating behavioural and psychiatric phenotypes has focused largely on a variable number of tandem repeats (VNTR) polymorphism in exon III, and in particular the presence or absence of the seven-repeat (‘long’) allele. See (Asghari, Schoots, Van Kats et al. 1994)(3), (Asghari, Sanyal, Buchwaldt et al. 1995)(4),(Ekelund, Suhonen, Jarvelin et al. 2001(5); Strobel et al. 2002)(6), (Okuyama, Ishiguro, Toru and Arinami 1999(7); Ronai, Barta, Guttman et al. 2001)(8). >Personality traits. 1.
