I would like to add some additional thoughts on shame as the intial response by those hearing about affect theory. As I do so, please keep in mind that according to Tomkins shame is triggered by any impediment to ongoing positive affect (the 2 positive affects being interest-excitement and enjoyment-joy).
Don and I have often discussed that the motivation of many who enter the mental health profession is to gain better understanding of themselves and their negative affect in order to lessen the effect of such negative affect on their lives. Since there are many very bright people in our profession, it is not surprising that the defensive maneuver of intellectualization is prominently featured among us. And there are many psychological theories that cry out for heavy intellectual investment and rumination but mostly avoid affect. Such intellectualization can be somewhat successful in ameliorating negative affect.
Just imagine what happens when you present affect theory to one who utilizes a great deal of intellectual defense and your excitement about the theory is obvious. Such a person is in a catch 22. If they are to be true to their intellect, then they must review the theory. Upon review, the theory contains a great deal that is obviously correct and well thought out. But if it is correct, then affect is the primary motivator of human behavior and to really understand the self, one must give up intellectual defenses that hide affect and tune more to the emotional self. This dilemma becomes an impediment for an intellectual's interest in understanding the self more clearly as they become caught between intellect and affect.
Another problem for many people is that once you begin to understand affect theory, you realize that affect surrounds us like the air we breathe and that nothing becomes conscious unless it first triggers affect. It's easy to feel a bit dumb (shamed) that something so obvious has been going on around us all our lives and we have missed it. Shame is often triggered in this situaton when the new information impedes our interest in a belief that we have incorrectly held, especially if that belief has formed the basis of our professional research and psychotherapy for many years.
I'm sure others have additional thoughts about this and look forward to seeing them here in the shame place in cyberspace.
