  1. Activations were thresholded at a whole-brain p value of < .001 uncorrected 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-corrected. Cerebellar activations are not reported due to incomplete coverage of the cerebellum depending on individual head size
