Interaction effects of maternal sensitivity with sex, and independent effects of maternal sensitivity, on left and right amygdala volume, fractional anisotropy (FA), and mean diffusivity (MD) as well as growth from 4.5 years to 6 years of age. Standardized β values are listed in the table. Note, *p < 0.05 level. The reduced model is not reported where the interaction model is significant.
