I don't know if different personality types experience shame in different ways, Hirsch. That's certainly a possibility. I'm guessing that shame is the same in everyone and the way it plays out/degree of recognition is the difference.
I think what you are talking about is generalized shame. It's that slow-burning fire that's always there eroding our self-confidence unawares. Shame a kid enough times and it can become generalized.
Certainly a singular focus on causation will distract from the goal and that may be an unconscious motivation.
Those flare-ups I describe, while seldom for me, are cause for caution to avoid rekindling the original fire. Make sense? Ach. Metaphor. . .
If someone is experiencing chronic shame it's a safe bet to say that at some formative stage someone, perhaps many, implied that that child's acts and thoughts were wrong in some way and that, over time, the person internalized those messages to mean that they were inherently flawed as a human being.
I used to think of it as , "Once upon a time Mom shamed me a lot. Now she doesn't have to follow me around and do it anymore. I carry her within me and can do it for myself." Heh.
