Abstract

Many daily activities require the weighting of risks and gains, and adjusting decisions based on this information. The present study investigates the role of left DLPFC in such normal-life, routine, but risky decisions. We expected that down-regulating the left DLPFC will reduce emphasis on gains such that less-riskier decisions, as captured with attitude and behavioral intention measures, are made. In study 1 (n = 56), tDCS naïve participants were recruited and subjected to high-definition cathodal tDCS stimulation (with intensity of 1.5 mA for 20 min) of the left DLPFC. A single-blind within-subject pre-post design was employed, in which each subject responded to realistic, normal life, ri..
