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.
