Most living humans grow up. But not everyone grows up well.

What makes the difference?

The Developmental Lens: A New Paradigm for Psychodynamic Diagnosis and Treatment answers this vital question for every clinician, patient, parent, and teacher who yearns to know.

This learned and evocatively written book offers Dr. Gwyneth Kerr Erwin's original Model of Seven Keystones of Healthy Development. Through her subsequent Models of Wounded and Traumatized Development, she takes the reader on a deep dive into what compromises each of those keystones when environmental gaps, failures, or trauma occur.

The story does end there. Not only hope but innovative pathways to healing are made tangible for those professionals and individuals who strive to resolve the consequences of developmental wounds. Using compelling case illustrations, Dr. Erwin serves as an expert guide to working with these fundamental and dynamic keystones in treatment to bring about transformed development.
