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.

This book brings together current theory and research about atypical attachments in infants and young children at developmental risk in order to illustrate and understand some of the key issues in cases that do not fit traditional attachment patterns.
