Novels. A. Average ERP waveforms in frontal, central, parietal, and occipital regions during processing of novel stimuli for highest (red) and lowest (blue) quartiles of externalizing and the internalizing factor scores. P300 amplitude reductions are found for those subjects with the highest externalizing and internalizing factor scores. B. Average ERP waveforms in frontal, central, parietal, and occipital regions during processing of novel stimuli for highest (red) and lowest (blue) quartiles of the shared internalizing/externalizing factor scores. Note: Quartiles were used here for illustrative purposes only; all analyses were conducted on the full continuous dataset.
