Introduction
The Behavioural Approach System (BAS) is one of the three major systems in the neuropsychological theory of personality known as the reinforcement sensitivity theory (RST) which recognizes other two defensive systems; the Fight-Flight-Freeze System (FFFS), responsible for the active avoidance of, and escape, from, aversive stimuli; and the Behavioural Inhibition System (BIS), responsible for passive avoidance and the detection and resolution of goal-conflict. It is assumed that the BAS represents a general-domain approach mechanism designed to solve the important evolutionary adaptive problem of attaining critical resources, such as food, water, sex and social status (Berridge, 2004; Berridge & Robinson, 2003; Kenrick & Shiota, …show more content…

We included two RST questionnaires in the study, since there exists a lack of conceptual agreement as to how the BAS scale should be conceptualized and measured. While some authors regard BAS scales to be similar to measures of extraversion, because they are assumed to reflect the reward system (Depue & Collins, 1999; Nettle, 2005; Pickering & Gray, 1999; Smillie, Pickering, & Jackson, 2006), others propose that it they should be more aligned with impulsivity (Torrubia et al., 2001). Furthermore, while some authors propose that the BAS is a unidimensional construct (Jackson, 2009; Reuter, Cooper, Smillie, Markett, & Montag, 2015: Smederevac, Mitrović, Čolović, & Nikolašević, 2014; Torrubia et al, 2001) others have made a persuasive argument for it being multidimensional (Carver & White, 1994; Corr, 2013; Corr & Cooper, 2015; Kenrick & Shiota, 2008). Hence, selective choice of one questionnaire may lead to different theoretical
