Ahhh psicopathy!
So, few years ago a quiet genius from NYC (Jeffrey Young) came out with a thing called "schema therapy" (there are other versions but i think the guy is a serious genius and i owe him a lot).
That starts from the assumption that in our early years we are poorly equipped to deal with crappiness of life.
Basically our main intellectual equipment is the amygdala (amy). Our neural connections between the sympathetic system and the prefrontal cortex are just start growing up....so in presence of drama (experiences that our amygdala is evolutionally trained to consider as life threatening) amy "hijacks the system" in order to self defend itself.
And builds a certain "model" of reality that is going to stay with us for many years to come (aka...the way you are screwed up).
This happens because while the prefrontal cortex takes many years to develop the amygdala builds up in the early phases of life and then substantially remains the same (well...i'm working on it).
On top of that there are 2 ways our thoughts emerges from our brain: a lower way and a higher way, subconscious and conscious. The first is faster. And as a way to bend and influence the higher way, slower, before it even forms, so when it does we come out with prefabricated judgments, fears and so on. Guess where the lower forms.
The secondary function of the amygdala is not just deal with crap in a split second. But deal with it in the long run based on that initial split second reaction: in abuse we get abused and maybe at the moment we reacting in very funky ways like...thinking to live a sort of dream experience... but also we need the people that is abusing us, so the amygdala also defines that way, this is the way it builds our fucked up model of reality in which we may stay entrapped forever.
This model is developed around a number of "maladaptive" schema in response to these \(often reiterated) experiences (i was referencing abuse, but also betrayal, being emotionally neglected, abandoned, feel you can't face reality alone, shame, etc http://www.schematherapy.com/id73.htm ).
Reaction to these schemas are loosely built upon a "fight (overcompensation), flight (just hide, stay away and decide you can't do anything about) or freeze(just stay there and accept the crap)" model.
Basically if you have been abused you might decide that that was good, that that is inevitable so just live with it or that you can't do anything beside stay away from it. None is a real response though.
You know when sometimes you realize that you keep having the same relationship with the same people and feeling like crap about it? Or you keep being an ass with others ?
This stuff normally develops in "normal" everyday neurotic behaviors. But they can become real behavioral disorders (narcissism, borderline,etc).
Psychopathy.
Although i had my share of crap (that in some ways i passed along in my hereditary line mostly in terms of fear) i haven't experienced what this incredible lack of empathy could be, nor the fragmented and extremely schizophrenic experiencing of reality it may bring with it.
It probably offspring from some original level of very intense violence and the acceptance of it.
Exposure to violence, abandonment often physically reflects into incapability to see reality in a organized way, lack of empathy, even permanent disorders in memory formation, exaggerate tendency to paranoia and anxiety.
I read of extremely narcissistic people becoming "geniuses" at something also in order to get a chance to humiliate other people and somehow "revive" an experience they learned to accept.
My response has been(is):
1) Mindful meditation : when you have those anxiety attack instead of get away from it...dwell in it. Stop there, live it and find what there is behind. Be aware of it, try to remember when it was the first time. Every time there is an emotional response over the lines there is something about you you should find out about. There are techniques to fight against it.
Maybe find a way to give back that kiddo you grew away from the respect and the space he deserves.
2) Neuronal reprogramming: fear extinction while you rebuild yourself in a different direction (thanks God i'm still capable to express some BDNF).
Work on your neurotransmissive balance, put yourself in control.
Psychopaths are not loved: are the fucked up response of fucked up open questions some other people has.
(sorry i know it sounded a little bit of a lecture, i still have some rage on me).
Peace, love and find yourself
