Figure 1.
Relationship between the Broken Promise score and the NGA.
A. Scalp field maps showing the positive centroid position on an anterior posterior axis (from 1 = most anterior, to 9 = most posterior) in the Go- (left panel) and NoGo-ERPs (right panel). The NGA was calculated as the Go-positive centroid position minus NoGo-positive centroid position (middle panel). B. Scatterplots of the correlations between the standardized Broken Promise score (i.e., larger numbers indicate a higher ratio of broken promises) and the Go-positive centroid (left), the NGA (middle), and the NoGo-positive centroid (right).
Figure 2.
Relationship between the Broken Promise score and the NoGo-P300 amplitudes.
A. Approximate scalp position of the electrodes used for the NoGo-P300 peak amplitude, FCz, Cz, CPz. B. Plot of the NoGo-ERPs (stimulus presentation at 0 ms). C. Scatterplots of the correlation between the Broken Promise score (i.e., larger numbers indicate a higher ratio of broken promises) and the NoGo-P300 peak amplitudes.
Figure 3.
Relationship between the Broken Promise score and source-localized brain activity related to response inhibition.
In the first two panels on the left, locations of the voxels that showed significant correlations are indicated in red (p<0.05, corrected) and, on the right, scatterplots are shown demonstrating the relationship between the Broken Promise score and source-localized brain activity (i.e., demonstrating the average correlation across all voxels that exceeded the corrected p threshold in the same cluster). We found significant positive correlations between the Broken Promise score and current density in the medial PFC/ACC (A; BAs 9, 10, and 32, peak voxel at MNI [x, y, z] –5, 40, 25), and in the lateral PFC (B; BA 8, peak voxel at MNI [x, y, z] 25, 30, 45).
