ABSTRACT An extensive literature suggests a link between executive functions and aggressive behavior in humans, pointing mostly to an inverse relationship, i.e., increased tendencies toward aggression in individuals scoring low on executive function tests. This literature is limited, though, in terms of the groups studied and the measures of executive functions. In this paper, we present data from two studies addressing these issues. In a first behavioral study, we asked whether high trait aggressiveness is related to reduced executive functions. A sample of over 600 students performed in an extensive behavioral test battery including paradigms addressing executive functions such as the Eriksen Flanker task, Stroop task, n-back task, and Tower of London (TOL). High trait aggressive participants were found to have a significantly reduced latency score in the TOL, indicating more impulsive behavior compared to low trait aggressive participants. No other differences were detected. In an EEG-study, we assessed neural and behavioral correlates of error monitoring and response inhibition in participants who were characterized based on their laboratory-induced aggressive behavior in a competitive reaction time task. Participants who retaliated more in the aggression paradigm and had reduced frontal activity when being provoked did not, however, show any reduction in behavioral or neural correlates of executive control compared to the less aggressive participants. Our results question a strong relationship between aggression and executive functions at least for healthy, high-functioning people.

    • "The current data, including the mediation model, indicate that these observed effects in executive function performance may be explained by underlying WM changes. The BPAQ is often used as a trait-based measure of aggression (Buss and Perry, 1992; Kramer et al., 2011), and as such, future research on the role of the executive network in aggression based on behavioral reports of specific aggressive or violent acts will be an important addition to the literature. However, the BPAQ, in particular the Verbal and Physical subscales that were significant here, have been shown to correlate with measures of violent behavior against others and against the self (Bushman and Wells, 1998; Archer and Webb, 2006; Zhang et al., 2012), thus we believe that BPAQ 'Acts' scores can serve as a good index of the likelihood of an individual engaging in real-life aggressive behaviors.

    ABSTRACT: Predicting which individuals may engage in aggressive behavior is of interest in today's society, however, there is little data on the neural basis of aggression in healthy individuals. Here, we tested whether regional differences in white matter (WM) microstructure were associated with later reports of aggressive tendencies. We recontacted healthy young adults an average of 3 years after they underwent research MRI scans. Via electronic survey, we administered the Buss Perry Aggression Questionnaire. We divided aggression into Aggressive Thoughts (Anger and Hostility subscales) and Aggressive Acts (Verbal and Physical subscales) and used Tract Based Spatial Statistics to test the relationship of those measures to WM microstructure. In 45 individuals age 15-30 at baseline, we observed significant relationships between Aggressive Acts and fractional anisotropy (FA) in a parietal region consistent with the superior longitudinal fasciculus (SLF). As the SLF has an established relationship to executive function, we performed an exploratory analysis in a subset of individuals with working memory data. Decreased FA in executive network regions, as well as working memory performance, were associated with later self-reported aggressive tendencies. This has implications for our healthy behavior understanding of as well as that of patient populations known to have executive dysfunction. © The Author (2015). Published by Oxford University Press.

    ABSTRACT: The primary purposes of this study were (a) to introduce the concept of executive functioning (higher-level cognitive processes which monitor events, actions, and outcomes) to the employee selection literature and (b) to provide an empirical assessment of executive functioning in relation to key selection variables. Two of the three main components of executive functioning (set shifting and inhibition) appear to have considerable potential for selection because of their unique nature (e.g., self-directed, goal-oriented) and because they appear to be only modestly associated with general mental ability. While our empirical results were inconsistent, there may be underlying reasons for this, such as the unstable nature of the retail job sector. We believe there is considerable justification for continued exploration of this unique and potentially promising construct, and identify a number of directions for future research. © 2013 The Institute of Psychology, Chinese Academy of Sciences and Wiley Publishing Asia Pty Ltd.
