Mother-infant interactive processes and infant behavioral and vagal stress recovery: Associations at 3, 6, and 9 months of age.

ABSTRACT: Mother-infant interactive processes, including matching social behaviors and repairing interactive ruptures, are proposed to foster infant stress functioning. However, little is known about the extent to which the concurrent relations between these dyadic processes and infant behavioral and vagal stress recovery change over the first year of life. In this study, 116 mother-infant dyads (55 girls) from a midwestern city in the United States completed the still-face paradigm at 3, 6, and 9 months. Using microcoding of infant and maternal behaviors (i.e., facial expressions, vocalizations, and gaze directions), we defined two dyadic states (positive match and mismatch) and measured dyadic matching as a composite of (a) the proportion of positive match and (b) latency to interactive repair (i.
