The capacity to represent experiences with external objects internally together with their associated affects, is a basic ego function, vital to reality testing and the experience of feeling alive and inside oneself. The affective reactions to these processes reflect the meaning and significance attached to these events and are the automatic reaction of the patient both to the analytic situation and outside of it. The analyst has an analogous reaction to that of the patient. These parallel experiences constitute Affective Center of an analysis and refers to the immersion both consciously and unconsciously, in the body/mind affective responses to the clinical situation of both patient and analyst-- a specialized example of how we all inhabit and make contact with ourselves, all the time, and everywhere, through how it feels to be inside ourselves all the time, relentlessly, and how that is how we know who we are, and, that we are, even when we feel we feel nothing or are unaware of how or what we feel. “I feel, therefore I am.” Attending to the Affective Center is therefore suggested as the first consideration in clinical engagement and is an as yet unexplored aspect of transference and countertransference dynamics.
