Activations were thresholded at a whole-brain FWE-corrected p value of < .05 with a cluster size of k = 10 voxels and reported only when they remained significant following FWE-correction for multiple comparisons at the cluster-level at p < .05 FWE. Cerebellar activations are not reported due to incomplete coverage of the cerebellum depending on individual head size
