No. :)
Levine:
Briefly, Porges's theory states that, in humans, three basic neural energy subsystems underpin the overall state of the nervous system and correlative behaviors and emotions. The most primitive of these three [Unmyelinated Primitive Vagus System] (spanning about 500 million years) stems from its origin in early fish species.* The function of this primitive system is immobilization, metabolic conservation, and shutdown. Highly traumatized and chronically neglected or abused individuals are dominated by the immobilization/shutdown system.
On the other hand, acutely traumatized people (often by a single recent event and without a history of repeated trauma, neglect or abuse) are generally dominated by the sympathetic fight/flight system. They tend to suffer from flashbacks and racing hearts, while the chronically traumatized individuals generally show no change or even a decrease in heart rate. These sufferers tend to be plagued with dissociative symptoms, includ-ing frequent spacyness, unreality', depersonalization, and various somatic and health complaints.
But does it really matter when you need to ask the question, "How to DEAL with fear?
When I hear residents of Seattle are breathing ten hot particles of Fukashima radiation per day and I experience fear; is this instinctive or learned?
I'd say, it's much more imaginary/learned fear than instinctive. It's not your senses that send signals of danger to your nervous system, that's your mind. It's YOU who triggers that fear. Yes, it is then perceived by your nervous system as real fear, and your body reacts accordingly, releasing chemicals, changing your heart beat, affecting your thinking. But there is no real enemy to deal with, so that fear along with all chemicals and body tension stays stored in your body.
In the case of real (physical) danger, it's mainly your body which is designed to deal with the situation. When fear is created by your mind, it's also the mind that has to solve the problem, so it doesn't really matter which part of the nervous system has been activated and in what way. To be more precise, it certainly doesn't hurt to know and understand your body's reactions, but it doesn't help much in dealing with that fear either.
g said:How do I determine whether a fear is instinctive or learned?
Does your nervous system's reaction protects you from the danger? Can it do its job?
g said:I don't see the value of your distinction, POB. It might be useful to distinguish whether the triggering data is based on old programs that distort the truth of the thinking and feeling centers evaluation of the data. Many fears are based on false programming of the emotional or thinking centers or mistaking new data for old. Is this what you mean by a learned fear?
I think it's crucial. :)
Again, I may be wrong but as I understand it right now, to find an answer to the question at hand we need to focus on the mind and not on the nervous system.
