The Structure of Parent–Child Dyadic Synchrony in Toddlerhood and Children's Communication Competence and Self-control

The aim of the present investigation was to examine parent–child synchrony and its link to children's communicative competence and self-control. Data were collected from 80 families with toddler age children (41 girls, 39 boys) during a laboratory assessment. Five components of parent–child dyadic synchrony were assessed during a semi-structured parent–child play activity at 18 months. Assessments of children's communicative competence and self-control were obtained at 36 months. Results indicated that parent–child synchrony, shared positive affect, and mutual compliance were highly intercorrelated components of dyadic synchrony. Moreover, children from highly synchronous parent–child dyads displayed more communicative competence and more self-controlled behavior. Mother–child mutual compliance and father–child shared positive affect were particularly significant contributors to children's self control. The associations between synchrony and child developmental adjustment remained significant after controlling for individual child and parent behavior. Developmental implications and suggestions for future research are discussed.
