Charting the dynamic character of mother-infant interaction requires using observational systems of sequential coding in real time. A longitudinal study was designed to approach maternal sensitivity in a more complex way using sequential analysis. The study was conducted with 20 high- and 20 low-risk mothers and their infants (aged: 3, 12 and 15 months) to examine the relation among mothers' ri...

This study focused on the predictive contributions of infants’ temperamental negative emotionality (proneness to fear, anger), sex, maternal responsivity, and their interaction on toddlers’ empathy-related responding to distress in 3 contexts. Ninety-eight infants and their mothers participated in a longitudinal study. When the infants were 10 months of age, mothers completed assessments of inf...

Social learning in infancy is known to be facilitated by multimodal (e.g., visual, tactile, and verbal) cues provided by caregivers. In parallel with infants' development, recent research has revealed that maternal neural activity is altered through interaction with infants, for instance, to be sensitive to infant-directed speech (IDS). The present study investigated the effect of mother- infan...

The study of dyadic interaction plays a major role in infancy research. To advance conceptually-informed measurement of dyadic interaction and integration across studies, we examined factor structure of individual parents' and infants' measures and dyadic measures from face-to-face interactions in two samples of 6-mo-old infants and their parents: mothers from a demographically heterogeneous sa...

Firstborn children's reactions to mother-infant and father-infant interaction after a sibling's birth were examined in an investigation of 224 families. Triadic observations of parent-infant-sibling interaction were conducted at 1 month after the birth. Parents reported on children's problem behaviors at 1 and 4 months after the birth and completed the Attachment Q-sort before the birth. Latent...

Human mothers interact emotionally with their newborns through exaggerated facial expressions, speech, mutual gaze, and body contact, a capacity that has long been considered uniquely human [1-4]. Current developmental psychological theories propose that this pattern of mother-infant exchange promotes the regulation of infant emotions [4-6] and serves as a precursor of more complex forms of soc...
