A, External motivation to respond without prejudice (EMS) emerged as a significant LV in behavioral PLS analysis. Brain–behavior correlations were similar across conditions. B, Patterns of whole-brain activity covarying with EMS are presented on lateral–anterior (left) and medial (right) views of the right hemisphere. All voxels with BSR ≥2.5 are displayed, irrespective of their respective cluster sizes. Note that the directionality of brain activity needs to be interpreted in conjunction with the plotted brain–behavior correlations in A. Increasingly positive BSRs in B indicate greater reliability of the negative brain–behavior correlations depicted in A.

BSR indexes reliability of each cluster. All BSR ≥ 2.5; all clusters ≥ 20 voxels.
*Clusters that no longer emerge after controlling for IMS are indicated with an asterisk. Cluster subregions are reported to illustrate the anatomic extent of the cluster beyond the peak BSR.
