A circle of traits: A perceptual mapping of the NEO-PI-R

Locating the Dark Triad in a Multidimensional Personality Space

The Dark Triad traits of Psychopathy, Machiavellianism, and Narcissism should be clearly recognizable within a multidimensional personality space. Two such personality spaces were investigated in this study: HEXACO (Honesty-Humility, Emotionality, Extraversion, Agreeableness, Conscientiousness, and Openness to Experience); and the Zuckerman-Kuhlman-Aluja Personality Questionnaire (ZKA-PQ) space (Extraversion, Neuroticism, Activity, Sensation Seeking, and Aggressiveness). Our sample comprised 289 participants (137 males, 145 females, 7 unspecified) who completed these three questionnaires: HEXACO-60, ZKA-PQ/SF, and the SD3, assessing the Dark Triad. We reduced the dimensionality of each space to that of a 2D representation using Smallest Space Analysis (SSA). Three research questions guided the data analysis: (a) Do the HEXACO and ZKA-PQ SSA spaces conform to the structure of a radex? (b) Will these spaces remain invariant following the entry of the Dark Triad traits into the analyses? (c) Where will the Dark Triad traits be located in each SSA space? For ZKA-PQ space, the structure was clearly indicative of a radex, both prior to entering the Dark Triad traits into the analysis, and subsequent to this. Psychopathy and Machiavellianism were in close proximity in the Aggressiveness region; Narcissism was positioned at the common origin. In contrast, HEXACO space did not conform to a radex; furthermore, the presence of the Dark Triad traits distorts this 2D SSA space.

The Correlation Between Personality Dimensions and Young People's Choice of a Medical Career

Objective: The research assumes that there is a correlation between personality dimensions Extraversion and Conscientiousness which mean autonomy, ambition and consistency of purpose, self-efficacy and determination for young people who want to aspire to a medical career.

Methods: In this study’s target group were included 130 students aspiring to a medical career, that participated in the summer school organized by UMF Tirgu-Mures in 2016, of which 25 (19%) male and 106 (81%) female, average overall age group being 17.23.

Results: Within the female group, the Pearson cross-correlation coefficient of Openness and Conscientiousness is r. Pearson (105) = − .20, p <0.05. The Pearson coefficient of cross-correlation between Extraversion and Conscientiousness is = − .20, p <0.05. The Pearson coefficient of cross-correlation between emotional stability and conscientiousness is r. Pearson (105) = .36, p <.001. In the male group, the Pearson cross-correlation coefficient between the Extraversion and Conscientiousness personality dimensions is r. Pearson (N = 25) = −.39 where p <0.05.

Conclusions: The Extraversion dimension of personality is a dynamic factor and motivator only when it is correlated with the Conscientiousness personality dimension. This indicates dynamism and autonomy, persistence in achieving goals, ambition, high motivation, interpersonal social intelligence and emotional stability, resulting a personality profile that matches one of the aspirants to a medical career.
