a Significant clusters resulting from the three-way interaction between group, target, and domain in bilateral insula. Images are thresholded at p <.005, 23 voxels (which achieves correction for multiple comparisons as calculated by 3dClusterSim). y and z refer to the anterior–posterior and inferior–superior dimensions, respectively. b Mean parameter estimates of activity from the left anterior insula cluster depicted in (a), for each target across domains, by group. Asterisk denotes means that significantly differ (p <.05, two-tailed)
