The behavior of a human player in a game expresses the personality of that player. Personality is an important characteristic for modeling the player’s profile. In our research we use the five factor model of personality, in which extraversion is a notable factor. Extraversion is the human tendency of being sensitive to rewards. This often results in humans seeking socially rewarding situations...

The agency facet of extraversion has been hypothesized to be based on individual differences in dopamine activity. Recent work suggests that resting posterior minus frontal electroencephalographic (EEG) slow oscillations (delta, theta) is both consistently associated with extraversion and sensitive to dopamine D2 receptor antagonist-induced changes in dopaminergic activity. Here we examine for ...

At the global level of the Big Five, Extraversion and Neuroticism are the strongest predictors of life satisfaction. However, Extraversion and Neuroticism are multifaceted constructs that combine more specific traits. This article examined the contribution of facets of Extraversion and Neuroticism to life satisfaction in four studies. The depression facet of Neuroticism and the positive emotion...

This study aims to investigate the neurostructural foundations of the human personality in young adults. High-resolution structural T1-weighted MR images of 71 healthy young individuals were processed using voxel-based morphometric (VBM) approach. Multiple regression analyses were performed to identify the associations between personality traits and gray matter volume (GMV). The Eysenck Persona...

AIM The aim of the study was the assessment of personality traits level (neuroticism, extraversion, openness to experiences, agreeableness, conscientiousness) and coping styles among patients with functional dyspepsia and irritable bowel syndrome. METHODS The Neo-Five Factor Inventory of Personality (NEO-FFI) and Coping Inventory for Stressful Situation (CISS) were used in the study. RESULT...

BACKGROUND The role of personality as a determinant of alcohol consumption has long been debated, but prospective evidence is scarce. METHODS We performed individual participant meta-analysis to examine the association between the Five-Factor Model personality traits (extraversion, neuroticism, agreeableness, conscientiousness, and openness to experience) and alcohol consumption using data fr...

Aim. The clinimetric aspects of Eysenck's two big personality factors (neuroticism and extraversion) were originally identified by principal component analysis but have been insufficiently analysed with item response theory models. Their relationship to states of melancholia and anxiety was subsequently analysed. Method. Patients with chronic idiopathic pain disorder were included in the study....

BACKGROUND The association between life events and anxious depression might be due to causality or to gene-environment correlation. We examined unidirectional and reciprocal causality and a gene-environment correlation model, in which genes that influence the vulnerability for anxious depression also increase the risk of exposure to life events. The effect of genes that influence environmental ...

Extraversion is a relatively stable and heritable personality trait associated with numerous psychosocial, lifestyle and health outcomes. Despite its substantial heritability, no genetic variants have been detected in previous genome-wide association (GWA) studies, which may be due to relatively small sample sizes of those studies. Here, we report on a large meta-analysis of GWA studies for ext...
