“…Although FA was significantly reduced in both left and right IFG (clusters 10 and 18) in alcoholics compared to control participants (see Table 2), it was the left IFG (cluster 18) that was more strongly associated with indices of drinking severity. This is interesting because structures of the dorsolateral prefrontal cortex, and in particular the IFG, have been implicated in processes related to self-control, decision-making, and reward sensitivity (Davidson & Irwin, 1999; Ravaja, et al, 2013). Specifically, there is the suggestion that approach-based decisions and withdrawal-based decisions may be lateralized to the left and right IFG, respectively.…”

“…Based on the available findings, we expected to find widespread abnormalities in FA in WM tissue among currently abstinent alcoholic individuals, particularly in the corpus collosum and in WM tracts underlying the frontal cortex. We were particularly interested in WM microstructure in the dorsolateral prefrontal cortex and the inferior frontal gyrus (IFG), because these areas have been implicated in processes related to self-control, decision-making, response inhibition, and reward sensitivity (Davidson & Irwin, 1999; Ravaja, et al, 2013). The importance of response inhibition and lateralization of reward-based decision making has been directly implicated in addictive behavior (see Goldstein & Volkow, 2011).…”

Background Evidence suggests that chronic misuse of alcohol may preferentially affect the integrity of frontal white matter tracts, which can impact executive functions important to achieve and maintain abstinence. Methods Global and regional white matter (WM) microstructure was assessed using diffusion magnetic resonance (MR) measures of fractional anisotropy (FA) for 31 abstinent alcoholics with an average of 25 years of abuse and approximately 5 years of sobriety and 20 nonalcoholic control participants. Data processing was conducted with FreeSurfer and FSL processing streams. Voxelwise processing of the FA data was carried out using TBSS (Tract-Based Spatial Statistics). Clusters of significance were created to provide a quantitative summary of highly significant regions within the voxel wise analysis. Results Widespread, bilateral reductions in FA were observed in abstinent alcoholics as compared to nonalcoholic control participants in multiple frontal, temporal, parietal, and cerebellar WM tracts. FA in the left inferior frontal gyrus was associated with drinking severity. Conclusions The present study found widespread reductions in WM integrity in a group of abstinent alcoholics compared to nonalcoholic control participants, with most pronounced effects in frontal and superior tracts. Decreased FA throughout the frontostriatal circuits that mediate inhibitory control may result in impulsive behavior and inability to maintain sobriety.

There is growing interest in exploring the potential links between human biology and management and organization studies, which is bringing greater attention to bear on the place of mental processes in explaining human behaviour and effectiveness. The authors define this new field as organizational cognitive neuroscience (OCN), which is in the exploratory phase of its emergence and diffusion. It is clear that there are methodological debates and issues associated with OCN research, and the aim of this paper is to illuminate these concerns, and provide a roadmap for rigorous and relevant future work in the area. To this end, the current reach of OCN is investigated by the systematic review methodology, revealing three clusters of activity, covering the fields of economics, marketing and organizational behaviour. Among these clusters, organizational behaviour seems to be an outlier, owing to its far greater variety of empirical work, which the authors argue is largely a result of the plurality of research methods that have taken root within this field. Nevertheless, all three clusters contribute to a greater understanding of the biological mechanisms that mediate choice and decision-making. The paper concludes that OCN research has already provided important insights regarding the boundaries surrounding human freedom to act in various domains and, in turn, self-determination to influence the workplace. However, there is much to be done, and emerging research of significant interest is highlighted.

“…Frontal asymmetry scores (L – R alpha) for the proximal and distal recordings were baseline adjusted for each participant so that they reflected changes in asymmetry, following past research on state frontal alpha asymmetry (e.g., Allen et al, 2001; Ravaja et al, 2013). The resultant asymmetry scores for the proximal and distal recordings were highly correlated, r = 0.63, p < 0.001.…”

Inhibition Underlies the Effect of High Need for Closure on Cultural Closed-Mindedness under Mortality Salience

et al. 2016

The hypothesis that people respond to reminders of mortality with closed-minded, ethnocentric attitudes has received extensive empirical support, largely from research in the Terror Management Theory (TMT) tradition. However, the basic motivational and neural processes that underlie this effect remain largely hypothetical. According to recent neuropsychological theorizing, mortality salience (MS) effects on cultural closed-mindedness may be mediated by activity in the behavioral inhibition system (BIS), which leads to passive avoidance and decreased approach motivation. This should be especially true for people motivated to avoid unfamiliar and potentially threatening stimuli as reflected in a high need for closure (NFC). In two studies involving moderated mediation analyses, people high on trait NFC responded to MS with increased BIS activity (as indicated by EEG and the line bisection task), which is characteristic of inhibited approach motivation. BIS activity, in turn, predicted a reluctance to explore foreign cultures (Study 1) and generalized ethnocentric attitudes (Study 2). In a third study, inhibition was induced directly and caused an increase in ethnocentrism for people high on NFC. Moreover, the effect of the inhibition manipulation × NFC interaction on ethnocentrism was explained by increases in BIS-related affect (i.e., anxious inhibition) at high NFC. To our knowledge, this research is the first to establish an empirical link between very basic, neurally-instantiated inhibitory processes and rather complex, higher-order manifestations of intergroup negativity in response to MS. Our findings contribute to a fuller understanding of the cultural worldview defense phenomenon by illuminating the motivational underpinnings of cultural closed-mindedness in the wake of existential threat.
