This work addresses the origins of attachment in mother-infant face-to-face communication. New patterns of relational disturbance in infancy are described. These aspects of communication are out of conscious awareness. They provide clinicians with new ways of thinking about infancy, and about nonverbal communication in adult treatment. Utilizing an extraordinarily detailed microanalysis of videotaped mother-infant interactions at 4 months, Beatrice Beebe, Frank Lachmann, and their research collaborators provide a more fine-grained and precise description of the process of attachment transmission.
