N = 18. Hem, hemisphere; R, right; L, left; BA, Brodmann area; Z, z-value for peak voxel, number of voxels indicated as thresholded at p < 0.0001, uncorrected; P, p-value for the cluster, corrected for multiple comparisons at the cluster level (p < 0.05, FWE). Areas that were no longer significant in analyses controlling for differences in subjective difficulty and response times are marked with a *.
