Sažetak
The relation between brain and personality is still undefined, and it seems that this topic has a long future in psychological research. This doctoral thesis focuses on the neuropsychological theory of personality – Reinforcement Sensitivity Theory (RST). It recognises three main dimensions ; Behavioural Approach System (BAS), Behavioural Inhibition System (BIS) and Fight/Flight/Freezing System (FFFS). There are currently several competing questionnaires designed to measure these constructs. These questionnaires are frequently used interchangeably without evidence to what extent they converge. Thus the aim of this thesis is to examine whether the results of RST studies conducted with different RST-based questionnaires are comparable. The objective is to provide the theoretical framework to interpret results from RST studies conducted with different questionnaires and to provide suggestions for further development of RST and its psychometric instruments. Six studies were conducted to test convergent and predictive validity of RST questionnaires. The results showed that RST questionnaires should not be used interchangeably since: (a) they do not converge ; (b) their BIS and FFFS scales do not predict defensive behaviour in the same way ; (c) they do not predict emotional and motivational outcomes after performance feedback in the same way ; (d) constructs measured by different BAS scales do not serve the same evolutionary function. The dissertation acknowledges the existence of four types of the BAS scales and provides the theoretical framework to reinterpret earlier findings from RST studies conducted with different questionnaires. The BIS scales converged highly with only one exception, while the FFFS scales converge, but show significant weaknesses in examining the theory.
