Coordination between infant and adult is thought to be essential to infant development. However, the study is theoretically and methodologically grounded in a dyadic systems perspective and relational psychoanalysis. Our automated apparatus explores the micro-second timing of 4-month infant-adult vocal coordination to predict 12-month infant attachment and cognition. This work also further defines a fundamental dyadic timing matrix that guides the trajectory of infant development.
