Extraversion has two central characteristics: (1) interpersonal engagement, which consists of affiliation (enjoying and valuing close interpersonal bonds, being warm and affectionate) and agency (being socially dominant, enjoying leadership roles, being assertive, being exhibitionistic, and having a sense of potency in accomplishing goals) and (2) impulsivity, which emerges from the interaction of extraversion and a second, independent trait (constraint). Agency is a more general motivational…

The findings provide the first evidence of a neuroanatomical dissociation between the personality traits of agentic and affiliative extraversion in healthy adults.

Effects of positive emotion, extraversion, and dopamine on cognitive stability-flexibility and frontal EEG asymmetry.

A dopaminergic basis for frontal EEG asymmetry, extraversion, and the modulating effect of positive emotions on stability-flexibility is supported and previous reports of cognitive differences between introverts and extraverts are extended.

Motivation and Personality 1 Running Head: MOTIVATION AND PERSONALITY Motivation and Personality: A Neuropsychological Perspective

Personality is strongly influenced by motivation systems that organise responses to rewards and punishments and that drive approach and avoidance behavior. Neuropsychological research has identified:

Personality predicts activity in reward and emotional regions associated with humor.

This work uses event-related functional MRI to address the putative neural and behavioral associations between humor appreciation and the personality dimensions of introversion-extroversion and emotional stability-neuroticism, and shows extroversion to positively correlate with humor-driven blood oxygenation level-dependent signal in discrete regions of the right orbital frontal cortex, ventrolateral prefrontal cortex, and bilateral temporal cortices.

Dopamine modulates frontomedial failure processing of agentic introverts versus extraverts in incentive contexts

The dissociations of FRN and DFMT suggest the existence of two nonredundant electrophysiological indices of feedback processing, both relating to dopamine and aE, and provide strong support for current dopamine models of aE and failure processing.

A neurobehavioral model of affiliative bonding: implications for conceptualizing a human trait of affiliation.

It is proposed that the capacity to experience affiliative reward via opiate functioning has a disproportionate weight in determining individual differences in affiliation.

On the nature of extraversion: variation in conditioned contextual activation of dopamine-facilitated affective, cognitive, and motor processes

The findings suggest that extraversion is associated with variation in the acquisition of contexts that predict reward, and individual differences in extraversion may be maintained by activation of differentially encoded central representations of incentive contexts that Predict reward.

Extraversion and Dopamine

Introverts were found to be much more susceptible to pharmacologically induced changes in D2 receptor activity than extraverts, providing additional experimental evidence for the notion that individual differences in D 2 receptor responsivity may represent a neurobiological substratum for the personality dimension of extraversion.
