Research on parent-child relationships demonstrates the importance of maternal sensitivity for the development of children's emotion regulation, social competence, and health; thus, it is important to understand the emotional-cognitive capacities underlying maternal sensitivity. We followed 120 mothers and their full-term infants from the newborn period to 5 months postpartum. Mothers' emotion recognition during the newborn period was measured using a validated facial emotion recognition task assessing discrimination (d') of six facial expressions of emotion: happiness, fear, anger, sadness, disgust, and neutrality. Maternal behavior at 5 months postpartum was coded from a mother-infant free-play session using Ainsworth's Sensitivity Scales. Preregistered analyses revealed that mothers' ability to detect happiness specifically (but not other emotions such as fear or sadness) in the neonatal period predicted greater observed sensitivity 4 months later, β = .30, p = .002, ΔR² = .08. Results suggest that maternal recognition of positive emotion may be uniquely predictive of sensitive behavior in low-stress parent-infant interaction contexts.
