How Do Regulatory Focus and the Big Five Relate to Work-domain Risk-taking? Evidence from Resting-state fMRI

Risk-taking in the 'work' domain constitutes a fundamental building block for a wide range of important decisions (e.g., investment) and behaviors (e.g., creativity) of individuals, groups, and organizations. Yet, what remains unknown is the neurofunctional basis of work-domain risk-taking (WRT) and how these brain substrates act as mediators in relating individual personality traits such as regulatory focus and the Big Five to WRT. This study, with a sample of 201 healthy full-time employees, investigated the above questions using resting-state fMRI. The results indicated that individuals who engage more in WRT showed increased brain activity (indicated by fALFF) in the right medial frontal gyrus (MFG) and right insula brain areas involved in goal-directed and self-regulated functions, therefore providing unique neuroimaging evidence for the notion that risk-taking is highly domain specific. More importantly, we found that fALFF in the right MFG and right insula areas has a significant mediating role in relating promotion focus and neuroticism to WRT, respectively, suggesting that these traits might have more important roles in associating with WRT, and the brain activity of the two regions (i.e., right MFG and right insula) may act as the underlying mediating mechanisms. Managerial implications are discussed.
