Frontocentral (Fz) ERN peak amplitude as a moderator of the relation between 14-mo BI and internalizing psychopathology in adulthood (age 26). The y axis shows simple slopes for the effect of BI on the internalizing factor (higher values indicates stronger positive relations). This plot shows the region of significance, with the dotted horizontal line indicating a simple slope of zero and the shaded region indicating 95% CIs around estimates of slope. BI was a significant predictor of internalizing psychopathology among those with more negative amplitudes of the ERN (<0.75 SD), but not those with more positive amplitudes.
