Differential effects of real versus hypothetical monetary reward magnitude on risk-taking behavior and brain activity.

The model accounted for 43.3% of the variance in the FRN amplitude difference ( F (2,37) = 14.13, p = 0.001), with delta risk-taking behavior accounted for 10.6% of variance ( B = 0.83, t = 2.13, p = 0.04) and reward condition accounted for 32.7% of the variance ( B = 3.11, t = 4.62, p = 0.001), whereas the interaction did not reach statistical significance ( p = 0.14).
