Summary
Written by AI, not yet AICS's view · claude-haiku-4-5-20251001This study examined how maternal mirroring (responsive facial and vocal interactions) during infancy affects children's behavior and emotional development at age 3.5 years. Young mothers and their infants were randomly assigned to either an infant carrying intervention or a book-reading control group during the first seven months after birth. Children whose mothers showed more mirroring had fewer behavioral and emotional problems, and this benefit was stronger for children in the carrying intervention group, who also showed better empathy and storytelling skills.
Key points
- Greater maternal mirroring at 7 months predicted lower internalizing symptoms, externalizing symptoms, and emotional reactivity at 3.5 years
- Infant carrying intervention significantly moderated the relationship between mirroring and socio-cognitive outcomes
- Among children in the carrying intervention, greater mirroring predicted higher empathy and narrative coherence
- No significant association between mirroring and empathy or narrative coherence was found in the book-reading control group
- Study followed 75 young mothers (average age 19.45 years) and their infants longitudinally from infancy to early childhood
Limitations
The study does not specify the country or cultural context where the research was conducted, making it unclear how findings might apply across different settings. The sample is relatively small and consisted of young mothers, which may limit generalizability to other populations.
Abstract
Little research has examined how affective caregiving processes, such as maternal mirroring, interact with physical caregiving contexts, such as infant carrying, to influence later child adjustment. The present study examined whether maternal mirroring during infancy prospectively predicted behavioral adjustment and socio-cognitive functioning, and whether participation in an infant carrying intervention moderated these associations. Participants were young mothers (N = 75; Mage=19.45, SD=2.39; 57.4% non-white) and their infants enrolled in a longitudinal randomized controlled trial of infant carrying. Dyads were randomly assigned to either an infant carrying intervention or a book-reading control condition during the first seven months postpartum. Maternal mirroring was assessed at seven months on the Still-Face Procedure using second-by-second coding of affective, vocal, and behavioral contingent interactions. Longitudinal outcomes at 3.5 years old included child internalizing and externalizing problems, emotional reactivity, empathy, and narrative coherence. Regression models using full information maximum likelihood estimation indicated that greater maternal mirroring predicted lower internalizing symptoms, externalizing symptoms, and emotional reactivity. Participation in an infant carrying intervention significantly moderated associations between mirroring and socio-cognitive outcomes. Specifically, greater mirroring predicted higher empathy and greater narrative coherence among children assigned to the infant carrying intervention but not among children in the control condition. Findings suggest that maternal mirroring during infancy may support children's emotional and behavioral adjustment, while infant carrying may strengthen the positive influence of mirroring on early childhood socio-cognitive developmental capacities.
