Note.

^aFI = fearful inhibition;

^bIC = inhibitory control;

^cMN = maternal negative behaviors.

^*MN composite z-score was winsorized such that scores that fell outside 3 SD of the mean for each time point were replaced by the next closest maternal negative behaviors score. This technique was applied to eight total outliers of the data. This mean is for MN after winsorization.

^dIP = internalizing problems.
