All clusters are reported at a voxel-level significance threshold of p < 0.001, small-volume corrected with p < 0.05 for familywise error (FWE) in regions of interest for a 15 mm sphere around peak coordinates as reported by Huettel et al. (2006), and cluster-level corrected with p < 0.05 for FWE outside regions of interest (marked *).
