Neurofunctional basis of work-related risk propensity: Evidence from fractional amplitude of low-frequency fluctuations and functional connectivity analyses

Work-related risk propensity (WRP), refers to an individual's risk-taking tendencies at the workplace, has been widely recognized as an essential predictor for individual performance. However, the neurofunctional substrates of WRP remain unclear. To fill this gap, we combined the fractional amplitude of low-frequency fluctuations (fALFF) and resting-state functional connectivity (RSFC) analyses to detect the neural underpinnings of WRP with a large sample of 173 full-time employment participants from different organizations and companies. The results of the fALFF analyses indicated that higher WRP was significantly associated with lower fALFF in the right cerebellum posterior lobe (rCPL). Furthermore, the findings from the RSFC analyses revealed that WRP was positively correlated with the functional connectivity of rCPL and right rolandic operculum (rRO). Critically, our results demonstrated the specificity of the correlations between WRP and intrinsic brain activity by excluding some confounding variables, in particular, the Big Five traits, after adjusting for control variables. Altogether, this study provides novel insights for the neurofunctional basis of WRP.
