The oldest known formal method of using spatial locations to remember data is the "method of loci". Used once by Roman rhetoric students (using a Greek system) when memorizing speeches. You will have heard of this one - in some ways it is like a platform game. You memorize the appearance of a physical location (for example, the sequence of rooms in a building). When a list of words, for example, needs to be memorized, You just put an object representing that word in one of imagined locations. To recall the list, the learner mentally walks through the rooms, noticing the objects placed there in virtual imagination.
Poets can help themselves by learning this method because it enables them to write on the move in their head; and many other tasks beside. Not least declamation - something I have never been able to get my head round.
