Grottbags Thinkings - A.I vs Brain (Positive/Negative Processings) #1

Does dealing with negative computations take more effort than with positives?
When brain rewards, you accept and move on. When brain negatives, you have a multitude of algorithms to process, guilt, shame, self doubt, anxiety etc… why?

How does this work with memory storage.
You remember more if you have negatives attached. But also, if you had a good time overall, you will forget the extent of how the bad things feel. The memory doesn’t feel any better though. Just less bad.

Alternative example,

Something bad at the time effects the moment terribly and everything that links and follows is tinted by that negative moment. Takes a lot to make it good/normal again.
But after x time has passed, you look back and can see funny or lucky sides of things. But why can’t you do that in the moment? Physically being in a situation? Does that mean the body is working too hard at the time as well as the brain, but when the brain is reflecting, even if you can imagine every single details, you body is still not in that place so time/space locations are important?

Is this the same for computers… or a reason they cannot get true A.I because a computer will also need to know the space in which is hosts, the body in which it fills in order to reach true A.I status?

Other wise, is there a maths equation that could implant the details of spacial awareness for a computer yet override the “physical distress” part. If so what, how/what? And in reverse could that then be used in humans to mark a route, method, thinking practice of thought trails in order to avoid feeling the stresses of a physical moment of doom?

Do computers get pre-programmed for rewarding behaviours that are correct? And do they have bad tellings if they have done something wrong?
