ERP data. (A) Significant differences of mean amplitudes in microvolt (μV): Post-hoc comparisons (high-risk (HR) vs. low-risk (LR); above, and win vs. lose; below) between groups at 15 electrode positions. Symbols in the underline represent the direction of significant differences (independent-sample-t-tests, p < .05). (B) Spherical spline maps (EEG-voltage, 0.25 μV/step) displaying difference maps per group for selected time points both during risk assessment and reward processing. ERPs are displayed to the right.
