Mother–infant co-regulation in dyadic and triadic contexts at 4 and 6 months of age
This study examined interpersonal co-regulation in 80 mother–infant dyads when interacting face-to-face and with an object, at the infant ages of 4 and 6 months. We found that co-regulation patterns differed between conditions and with development. Under the dyadic condition, the dyads were mostly unilateral, with only the mother attending to the infant's focus, while in the triadic context, they were mostly symmetrical, with both mother and infant mutually engaged.
