We touched on a little bit of how a brain works in one of my engineering subjects in first year. The shortcuts paulstreats mentioned briefly are somewhat more basic. The brain's shortcuts( known as heuristics
) include things like having recognising vertical lines, recognising vertical lines, colours [take note of the u
] and other basic functions which I can't remember offhand. You also have other heuristics which deal with decision making like the recognition heuristic which means that you chose something that you recognise or the take-the-last heuristic which means you do what you did last time.
I'll see if I can find some of my old books if anyone is interested or a quick wiki search is what I used to pass the online tests!
