The gradual change that has taken place in psychoanalytic technique within the Kleinian and post-Kleinian school of psychoanalysis since its emergence is essentially a paradigmatic shift in the way the transforming factor in psychoanalysis is perceived: from the centrality of interpreting unconscious phantasy (particularly when expressed in negative transference), to a refocusing on the patient's introjection of the analyst's mind, including the complex functions of reverie, mental digestion and so on, of which interpretation is but one possible expression amongst many. In this paper I will bring clinical material from a case I supervised to illustrate how these technical changes, manifested in clinical work, facilitate internal change in the patient. I argue that contemporary technique is now closer and more faithful to the Kleinian theory of mental development, and better reflects the central role it has always assigned to the good object and its introjection as a vehicle for development and change both in daily life and in analysis.
