How does our intelligence function?


My theory is the following: our INTP brain try to be the most efficient and cost effective possible when it comes to achieve a certain difficult cognitive task . For that same reasons, it is impossible for our brain to work continuously.

It works solely when it's necessary(lazy brain !) , and more.. when it is a matter of life or death or when there is a great outcome. Many people have reported that their brain power varies depending on the stress/ emotional environment. Some people are only able to study few hours/ days before the exam when the stress level is maximal, otherwise they cannot. Studies(I have no references!) and personal experience have demonstrated that acute exposure to stress( urge to do something, "must study many pages few days before an exam or you die") enhances memory, focus, cognitive skills... While chronic exposure to stressors diminishes mental abilities!

So My theory would be that chemical environment of the brain( depression,schizophrenia, mood, excitement, serotonin, adrenaline, histamine,..etc) enhances or inhibits cognitive skills, and that it would be responsible of the variance in our aptitudes on a daily basis(lazy b but excitable brain !) . There is already evidence that brain efficiency is not the same in the morning or at night.
That would also explain why certain people with a potential do not always perform correctly.Some people can't just work without the stress/ adrenaline factor, otherwise they get bored.


So what do you think of this? Do you think intellect/ cognitive skills depends also on emotional components and on the capacity of the brain to be excitable in INTP's or in general population?

Stress could be defined as: a situation that the subject does not feel they have the resources to deal with.

As far as I am aware, the hypothalamus receives the distress signals and stimulates the pituitary gland to stimulate the adrenals, releasing the 'stress hormone' cortisol that is involved in blood sugar regulation along with insulin - releasing more glucose into the blood.

Not sure how the blood-brain barrier plays into this (if it does at all) but the brain runs on glucose so... viable explanation?
