abstract = {Detecting the factors associated with financial decision-making is an unresolved challenge when trying to predict digital
financial behavior. This paper reports experimental results on both neuropsychological and neuronal correlates of risktaking
and betrayal aversion among 121 healthy participants (Xage=21.7; SD = 2.8). A questionnaire on financial habits was
administered, followed by neuropsychological tests and a magnetic resonance imaging session while participants viewed
videos depicting both traditional and digital economic transactions. Participants also completed a computerized version
of trust and risk games. Results reveal that Sensitivity to Punishment and Negative Urgency significantly predict risk
behavior. High betrayal aversion was associated with greater sensitivity to punishment as well as lower volume in temporal
areas. Cluster analysis identified two distinct psychological profiles based on betrayal aversion scores, highlighting
differences in sensitivity to punishment, negative urgency, positive urgency, and trust game score. Furthermore, cortical
thickness comparisons revealed differences between low and high-aversion groups, particularly in the temporal, parietal,
and insular areas. White matter analysis indicated less integration in specific tracts among individuals with high betrayal
aversion. These findings suggest the influence of neuropsychological factors on the adoption of risky financial behaviors
and emotional response to betrayal.},
