Genetic analysis of data from 2,680 adult Australian twin pairs demonstrated significant genetic contributions to variation in scores on the Harm Avoidance, Novelty Seeking, and Reward Dependence scales of Cloninger's Tridimensional Personality Questionnaire (TPQ), accounting for between 54% and 61% of the stable variation in these traits. Multivariate genetic triangular decomposition models we...

The paper investigates the relationships between personality traits and expert manual annotation of unscripted speech. The analysis is based on the results of a psycholinguistic experiment in which the participants were asked to annotate sentence boundaries in transcriptions of Russian spoken monologues. Personality traits were measured using the Eysenck Personality Inventory and the Five Facto...

The aim of this paper is to present an experimental investigation conducted to assess the impact of personality factors on the formation of Spatial Presence. Four different media -linear text, hypertext, film and virtual environmentand eight different experimental manipulations were applied. Spatial Presence was measured using the MEC-SPQ questionnaire. Personality was measured using the NEO-FF...

How are retrospective accounts of family rearing environments linked to adult personality? We addressed this question by measuring both domains in a sample of 180 reared-apart twins. Twins completed extensive measures of rearing environments (the Minnesota-Briggs History Record, the Block Environmental Questionnaire, the Family Environment Scale, and the Physical Facilities Questionnaire) and a...

There is an increasing body of research investigating relationships between personality factors and crash involvement. This research estimates that personality factors account for about 10 to 20% of the variance in crashes. However, there are a number of limitations associated with this research. Most studies are cross-sectional or retrospective in design, are based on self-reported crashes or ...

Previous research has shown that personality characteristics, such as sensation seeking (SS), are strong predictors of risk-taking behavior during adolescence. However, the relationship between levels of SS and brain response has not been studied during this time period. Given the prevalence of risky behavior during adolescence, it is important to understand neurobiological differences in rewar...

Judging others' personalities is an essential skill in successful social living, as personality is a key driver behind people's interactions, behaviors, and emotions. Although accurate personality judgments stem from social-cognitive skills, developments in machine learning show that computer models can also make valid judgments. This study compares the accuracy of human and computer-based pers...
