Significant clusters and their respective maxima in scalp-time space (p_FWE < 0.005; cluster level, minimum cluster size, 15 voxels; contrast weights: [−1.5, −0.5, 0.5, 1.5]). Positive parametric effects can be attributed to ERP amplitude increases in the positive polarity for increasing rating levels, while negative parametric effects reflect amplitude increases in the negative polarity.
