Interactions between action category and age group (A) and expertise group (B). Results were calculated using a voxel-wise threshold of p<0.001 and a minimum cluster size of 10 voxels. Only clusters are reported that reached cluster-corrected significance of p<0.05, FWE corrected. Up to three local maxima are listed when a cluster has multiple peaks more than 8 mm apart. Abbreviations for brain regions: PCC, posterior cingulate cortex.
