The theme of this thesis is to investigate the dimensions of extraversion-introversion as one of the fundamental characteristics of human personality. In the theoretical part, we are bringing a brief history of efforts to define and describe this dimension, and we also introduce some current concepts and appropriate diagnostic methods. Furthermore, in the theoretical part, we briefly focus on the specifics of personality dimensions of extraversion in the context of artistically creative personality. The aim of this work is not to contribute to answering the question about the existence of a relationship between the creative artistic process and a creator's introversion or extraversion. Artists are a psychologically widely studied group so we decided to use some specific knowledge about their extraversion or introversion in our research. The aim of the practical part of our thesis is to contribute to the search for the possible connections between personality theories of H. Rorschach and H. J. Eysenck. Both theories and methods (the Rorschach test and Eysenck Personality Questionnaire - EPQ-R) are based on the neurobiological characteristics of the individual and typical ways of responding but they differ in their approach. H. J. Eysenck's assumption of rather less extraversion of artists, as well...

This study examines spontanneous, laic personality ratings of face in comparison to following questionnaires: 16 PF, EPQ-R, NEO-PI-R. We've focused on how people spontaneously rate personality from face in relation to traits which are examined by said questionnaires. We tried to discover which traits are part of questionnaires but not included qualiative ratings and vice versa which traits can be found in laic descriptions but not in questionnaires. We used data from previous studies which provided us with two independent data, self-reports and ratings of facial photographs. Ratings were sorted out and compared to questionnaires. Most of the traits from qualiative data were also included in NEO-PI-R, specifically 90,4% of traits from self-reports and 82,90% of peer reports. 16 PF covered 88% and 77,81% of traits, EPQ-R 86% and 75,94% respectively. The least covered factor overall was Self-Reliance (16 PF) which included only 0,4% of all traits from self-reports. We have not found any factor which would be completely neglected in qualiatitve descriptions. Atractivity and physical traits were one of the main traits among those left unclassified. As with atractivity itself there was wide range of traits that we are unsure of how much personality relevant they actually are. Among unclassified traits...

Ethnic status is one of the most protected demographic groups in terms of test bias and discrimination in personnel selection, as such bias breaches many laws, morals, and ethical procedures. To date there has only been two published studies that have used New Zealand relevant ethnic groups when analysing whether personality measures used in pre-employment settings exhibit different mean scores. The present thesis performed a systematic evaluation on the impact of ethnicity on personality traits. The study examined the impact of ethnicity on NZ Army Officer applicant personality assessment scores measured by the EPQ-R and GPP-I. Four ethnic groups (NZ Europeans, Mâori, Pasifika, and Asian) were analysed for mean trait score differences among ethnic groups, the stability of these differences across different personality inventories and models, the variance of personality traits, the impact of ethnicity on age and gender relationships with personality traits, and how these differences were related to employment selection outcomes. The analyses revealed that ethnicity did have some impact on mean personality assessment scores used in the study. However, these were mostly small differences among ethnic groups. In addition, most of these differences found on the EPQ-R and the GPP-I were not consistent across inventories and models. There were no significant variance differences found on personality traits among ethnic groups. While initial analysis suggested that ethnicity did not influence the relationship between age and gender on personality assessment, further examination suggested that the relationship between gender and personality was impacted on by ethnicity. There were reassuring results found for New Zealand psychologists and HR specialists, as only two of the twelve traits analysed showed moderate differences on traits that were related to selection outcomes. However, for the NZ Army OSB selection process the findings in the present study indicate that the Lie scale on the EPQ-R and the Vigor trait on the GPP-I may need to be interpreted with caution for Asian and Pasifika groups. These results are discussed in terms of implications for personality theory, measurement, and the direction of future research.
