Fig. 4.

Left: Mu-activity in premotor cortex (BA 6, X: 42, Y: −5, Z: 65) is strongly correlated with social competence scale. The scatterplot in the lower panel indicates an r = .74 with p < .01 for this region (average over voxels). Right: An inverse correlation was obtained for prefrontal cortex (BA 8, X: 30, Y: 39, Z: 39). The scatterplot in the lower panel indicates an r = −.66 with p < .01 for this region (averaged over voxels). Note the close similarity of the regions identified in the correlation analysis and those identified in the group comparison (Fig. 2C) and the almost perfect separation of the groups in the scatterplots.
