Stereotactic coordinates and t‐values of the foci of maximum activation for the DES and the SE reasoning tasks (P < 0.001, uncorrected for multiple comparisons; t > 4.14). Coordinates (x, y, and z) are expressed in MNI space adopted by SPM99, in terms of distance (in mm) from the anterior commissure. The foci were anatomically localized on the standard stereotactic brain atlas developed by Talairach and Tournoux [1988] after correcting for differences between the MNI and Talairach coordinate systems using a nonlinear transformation.

DES, descriptive; SE, social‐exchange; BA, Brodmann area; L, left; R, right.
