Main effects of brain response during gain anticipation against no gain anticipation for each age group. Results are thresholded with P < 0.05 corrected for multiple comparisons using a Monte Carlo simulation based cluster‐size correction. Coronal (Y = 12, upper column) and axial cuts (Z = −2, middle column) as well as a top view on the brain (lower column) are shown. R = right, L = left, A = anterior, P = posterior.
