This article is the result of a client-centered and experiential lecture of the main writings of D.N. Stern through the eyes of a therapist working with adults.
After a general survey of his work (part I), part II explains his developmental psychology, with special focus on his ideas about attunement between mother and child. Some of his theoretical concepts are explained. Finally, some speculations are made about the relevance of this developmental view for client-centered an experiential therapists.
Part III gives an idea of Sterns' theoretical thinking about psychotherapy. The model of the Boston Process of Change Study Group is proposed and checked against the client-centered and experiential view of psychotherapy.
The final section summarizes the importance of this body of knowledge for client-centered and experiential therapists.
The tPeP (Journal Person-centered experiential Psychotherapy) is the scientific journal for Dutch and Flemish psychotherapists, psychologists, and psychiatrists, that work from, or are interested in a client-centered perspective.
