Note. **p < .01, *p < .05, †p < .10. HCV = hippocampal volume; AGV = amygdalar volume, res = residualized for age, length of gestation and intracranial volume; PSS = perceived stress scale, SES = socioeconomic status, SE = social-emotional. The associations with Bayley outcomes are examined within the mother-infant dyads with available data on social-emotional development (M6 N = 73 and M12 N = 63).
