You're talking about value systems. It is my understanding that these
have been found in the brain and central nervous system, corresponding
to (for instance) the ability of a person to hold something in their
hand.

I don't know whether the "!" value system itself has value systems,
but it is possible.

Apparently, they work by averaging (in some sense). In that, when the
'note this' occurs, all the inputs weights are changed to reflect the
current inputs further.

Any inputs that have nothing to do with the 'note this' average out,
but the ones that have a real link, don't.

Some of the things that I expect to be important:

- stress
- holding things in hands
- sex
- talking
- listening
- eating
- physical contact

This is probably why holding hands and talking with your (new)
girlfriend, and eating chocolate is so popular. ;-)
