Neurobiology of the structure of personality: Dopamine, facilitation of incentive motivation, and extraversion

In the citing paper

“The activation and sustainment of achievement motivation has been conceptualized to be accomplished by central representations of delayed rewards 20 .”

“dopamine plays a key role in individual differences on behaviour (Depue & Collins, 1999; Norbury & Husain, 2015; Smillie, 2013; Smillie & Wacker, 2014)”

“Numerous animal, human pharmacological, and molecular genetic studies indicate that dopamine (DA) modulates activity within this circuitry to promote IM (Depue & Collins, 1999; Koob & Volkow, 2010).”

“High-incentive states are characterized by positive attentional biases, approach-related motor behavior, and subjective states of anticipatory engagement, especially under novel conditions (Depue & Collins, 1999; Segerstrom, 2001; Vollstadt-Klein, Loeber, Richter, Kirsch, Bach et al., 2011).”

“IM is neurally mediated by circuitry that includes the midbrain tegmental region, the striatum, core limbic regions such as the extended amygdala, the anterior cingulate, and medial regions of the orbitofrontal cortex (Depue & Collins, 1999).”

In the citing paper

“Despite an overall peak in DA signaling and general maturational processes that occur in adolescence, there is considerable individual variability both in DA signaling, as well as DA-influenced behaviors, likely due to a combination of genetic and environmental factors (Depue and Collins 1999; Frank and Hutchison 2009).”

“Importantly, the ACC is rich in dopamine receptors and recognized as a core node within the incentive motivational system (Depue and Collins, 1999; Haber, 2003; Berridge, 2004), suggesting the possibility of a neurochemical basis for the aggregation of regions that showed stronger activation likelihoods in adolescents relative to adults.”

In the citing paper

“Relative to negative valence, positive valence yields more consistent processing in the PCC, accumbens, and lateral occipital cortex, suggesting a link between the limbic-motor interface that allows approach to incentive-based stimuli (Depue and Collins, 1999) and the facilitation of self-referential cognitive activity that is mediated by the PCC (Johnson et al., 2002; Kelley et al., 2002).”

In the citing paper

“Peaks in dopamine activity during adolescence and subsequent declines into adulthood may underlie adolescents’ sensitivity to positive reward contexts (Wahlstrom et al., 2010a) given that midbrain dopamine projections to the limbic, striatal and frontal regions facilitate incentive motivation (Depue and Collins, 1999; Björklund and Dunnett, 2007; Haber, 2003).”

“For example, Agreeableness showed a small but statistically significant positive correlation with use of Sexual words (ρ = .08, p < .05), and Extraversion, a trait often associated with increased incentive facilitation and agentic behavior (Depue & Collins, 1999), correlated negatively with several categories reflecting goal orientation and work-related achievement (Occupation, Job/work, and”
