My dissertation is focused on analysing the importance of personality typology during the choice of career. The theoretical part is aimed at the clarification of related key concepts, summary of knowledge concerning the personality typology and explanation of chosen theories dealing with personality typology. I paid particular attention to the type indicator MBTI, which is subsequently used in the practical part. The methodological part follows the theoretical part. The methodological part delimits the particular phases of the research and together with the theoretical part serves as a basis for the practical part. Within the practical part the personality typology issues used during the choice of career are analysed through the research and subsequently the interpretation of ascertained results is mentioned.

Thesis (Ph. D. (Psychology)) -- University of Limpopo, 2019 / The present study investigated the gender moderated relationship between the dark tetrad personality types and sexual behaviours among African university students. Two studies were conducted using conveniently selected samples from two universities in Limpopo, South Africa. Both studies were quantitative in nature using a cross-sectional research design. An integrative theoretical approach was utilized in the conceptualization of the studies, and data was analyzed using structural equation modeling (SEM). The first study (N = 261) determined the relationship between the dark tetrad personality types and sexual behaviours conceptualized as infidelity, sexual aggression, and sociosexuality. It was only sadism that had the capacity to predict infidelity and SOI-R desire. Regarding moderation, the results showed that gender only moderates the associations between Machiavellianism and SOI-R behaviour, psychopathy and SOI-R attitude, and sadism and infidelity. The second study (N = 275) examined if the relationship between the Dark Tetrad personality types and socio-sexuality would be mediated by adversarial sexual beliefs (ASB) and ambivalent sexism (benevolent [BS] and hostile sexism [HS]). Results showed that the relationship between sadism and SOI-R behaviour and desire, Machiavellianism and SOI-R behaviour and desire were fully mediated by BS, and the association between sadism and all the SOI-R components, Machiavellianism and all the SOI-R components, and psychopathy and all the SOI-R components were fully mediated ASB. Additionally, gender only moderated the ASB mediated associations between sadism and SOI-R behaviour, and sadism and SOI-R attitude. Ultimately, the study advances recommendations for future studies. / NRF ( National Research Foundation)

In der Verhaltensökologie hat das Interesse an der Persönlichkeit von Tieren in den letzten zwei Jahrzehnten zugenommen und man geht davon aus, dass verschiedene Verhaltenstypen wichtige ökologische und evolutionäre Konsequenzen haben. Diese Konsequenzen sind besonders ausgeprägt, wenn eine konstante Verhaltensweise mit anderen Verhaltensweisen (sog. Verhaltenssyndrome) oder mit Life-History-Merkmalen (sog. Pace-of-life-Syndrome) korreliert. Bisher haben Studien zu Verhaltens- und Pace-of-life-Syndromen zu keinen schlüssigen Ergebnissen geführt – manche Hypothesen wurden bestätigt, andere jedoch nicht. Man nimmt an, dass Kovariation zwischen Merkmalen von der Umwelt geprägt ist. Da jedoch Tiere in Gefangenschaft in diesen Studien überrepräsentiert sind, kann dies ein möglicher Grund für die recht uneindeutigen Ergebnisse sein. Um diese Wissenslücke zu schließen, erforschte ich die Entstehung von Verhaltens- und Pace-of-life-Syndromen in einer Wildpopulation juveniler Haie, die relevanten ökologischen Bedingungen ausgesetzt waren. Ich untersuchte (1) ob ein Syndrom zwischen zwei konstanten Verhaltensweisen besteht und ob das Auftreten des Syndroms kontextabhängig ist, (2) ob ein Trade-off zwischen Wachstum und Mortalität durch Explorationsverhalten vermittelt wird, und (3) ob Persönlichkeit das Nahrungshabitat der Haie vorhersagen kann und ob dieser Zusammenhang kontextabhängig ist. Ich dokumentierte ein Verhaltenssyndrom das über Jahre und Standorte hinweg inkonsistent war und von inter-individueller Konkurrenz abhing. Ein Zusammenhang zwischen Explorationsverhalten und einem Wachstums-Mortalitäts-Trade-off war nur bei geringem Prädationsrisiko zu beobachten. Zudem sagte das Explorationsverhalten Nahrungshabitate nur bei geringem Prädationsrisiko vorher. Zusammengenommen deuten diese Ergebnisse darauf hin, dass die ökologischen Bedingungen eine entscheidende Rolle bei der Entstehung und Ausprägung von Persönlichkeits- und Pace-of-life-Syndromen spielen. / In behavioural ecology, interest in the study of animal personality (i.e. consistent individual differences in behaviour across time and/or context) has increased in the last two decades as it is believed to have important ecological and evolutionary consequences. These consequences are especially pronounced when a behaviour that is consistent covaries with other consistent behaviours (i.e. behavioural syndrome) or with life-history traits (i.e. pace-of-life syndrome). So far, studies of behavioural and pace-of-life-syndromes have produced ambiguous outcomes (e.g. hypotheses are sometimes verified and others not), and the prominence of studies on captive animals (i.e. as opposed to wild animals) in the literature may be a reason for inconclusive results as trait covariation has been hypothesized to be environmentally driven. To address this knowledge gap, I investigated the emergence of behavioural and pace-of-life-syndromes in a wild population of juvenile sharks subject to relevant ecological pressures (e.g. predation risk, inter-individual competition). I explored (1) whether a behavioural syndrome existed between two consistent traits (exploration and sociability) and whether the appearance of the syndrome was context dependent, (2) whether a growth-mortality trade-off was mediated by exploration personality and (3) whether personality could predict the foraging habitat of sharks and whether this link was context-dependent. First, I observed a behavioural syndrome between sociability and exploration personality which was inconsistent across years and locations and was dependent on inter-individual competition. Then, I found the association between exploration personality and a growth-mortality trade-off to only be observable in low predation risk. Similarly, I found that exploration personality only predicted wild foraging habitat when predation risk was low. Overall, these results suggest that ecological conditions play a crucial role in the emergence and the shaping of personality and trait association. This thesis offers a possible explanation for the ambiguous results of previous studies and highlights the importance of increasing the focus on wild study systems that are subject to relevant ecological pressures in future animal personality research.

An exploratory study was undertaken to investigate the relationship between personality preference groupings, as described by Jung’s (1959) type theory, and emotional intelligence, as measured by Bar-On’s emotional intelligence quotient (Bar-On, 1997). The sample group consisted of 1 121 recruitment candidates for a South African investment bank. The sixteen personality types, as measured by the Myers-Briggs Type Indicator, were represented in the sample. The statistical analysis conducted for this study included comparison of means, correlation analysis and analysis of variance. The results indicated statistically significant relationships between the preferences of Extroversion, Judgement, their combined preference grouping and emotional intelligence. No statistically significant relationships were found between the preference groupings of Intuition and Thinking, Sensing and Thinking, Intuition and Feeling, and Sensing and Feeling. The preferred Feeling preference type consistently scored the lowest in terms of emotional intelligence scores. / Industrial and Organisational Psychology / M.A. (Industrial and Organisational Psychology

The aim of this study was to determine whether personality types are predictors of team roles in order to make recommendations for the use of personality types, in conjunction with team roles, in selection and teambuilding. The study was conducted among 50 professionals and managers in Western Cape organisations. The data was collected by means of the Myers-Briggs Personality Type Indicator (MBTI) and the TearnBuilder Model of Team Roles. Supporting evidence, although not sufficient, indicates that the Extraversion (E) personality type is a positive predictor of the Driving Onward team role and a negative predictor of the Delivering Plans team role. The Introversion (I) personality type is not a predictor of any team role. The Sensing (S) personality type is a negative predictor of the Driving Onward team role and a positive predictor of the Delivering Plans team role. The Intuition (N) personality type is a positive predictor of the Driving Onward team role and a negative predictor of the Delivering Plans team role. The Thinking (T) personality type is a positive predictor of the Controlling Quality team role. The Feeling (F) personality type is not a predictor of any team role. The Judging (J) personality type is a positive predictor of the Planning Ahead team role, and the Perceiving (P) personality type is a negative predictor of the Planning Ahead team role. It can be assumed that the full range of personality types will be a predictor of the full range of team roles, should a larger sample size and geographical sample group be included in the study. / Industrial and Organisational Psychology / M.A. (Industrial Psychology)

The general purpose of this study was to determine the relationship between cognitive styles and personality types in order to gain insight into the placement of leaders within the context of current and future organisational demands. The study was conducted among 123 managers within the information technology environment of a South African financial institution. Data was collected by means of the Cognitive Process Profile (CPP) and the Myers-Briggs Type Indicator (MBTI). Supporting evidence, although not sufficient, indicates a probable relationship between cognitive styles and personality types. The assumption can therefore be made that the relationship between cognitive styles and personality types will be more pronounced among a more geographically distributed sample group which includes sufficient diverse respondents regarding the different cognitive styles and personality types. / Industrial and Organisational Psychology / MCOM (Industrial Psychology)
