Freud and others have attempted this kind of thing before. Freud had the Ego, Id, and Super Ego, and science is starting to understand the separation within the brain that are similar to these things.
For instance, if you youtube "phantoms in the brain" (at work, can't post youtube links)
In my study of the body, genetics, neurology, and other stuff, I am formulating a "Hierarchy of Influence" ... think of the OSI model for humans.
1) Surface
Measurable actions and words and behaviors, what people see/hear
2) Rational/Logic
This is what we use when making decisions/planning
3) Impulse
This is information that comes from more primitive parts of the brain, like adrenaline reactions and fear.
4) Subconscious/Memory
Self explanatory. This is where habits reside
5) Physical/Body
This is things like eyes, hormones, ears, (etcetera) are.
Okay, time for a practical example of how this system works.
a) The eyes see a face
b) the face is analyzed by our most primitive centers to discover expression, and if we know this person
c) depending on the information from b) we cultivate an impulse reaction (If it's someone we hate/fear we get adrenaline, for instance)
d) also, depending on the information from our subconscious and impulse, we analyze what to do and how to react
e) we finally verbalize our reaction/action
Now, there is a problem with this heirarchy, and that is that it doesn't take into account things like oppositional centers in the brain, though technically they exist in the same layer. For instance the Impulse center responsible for lying is in one hemisphere and the inhibitor is in the other hemisphere.
Once I get home, I will cook up a graphic for this.
Does anyone know of anything similar to this?
