Image via WikipediaThose of us at Braintenance Central (make a quick left at the Parietal lobe, and follow the cues) believe that using a mnemonic or other "conscious device or technique" in order to improve some aspect of mind functioning is not against the rules -- in fact, if it helps, we like to encourage it. There are so many wonderful devices and techniques for improving various aspects of mental functioning that it makes one's head spin.
Again, we feature a listing of the most popular memory techniques, courtesy of BrainMetrix:
The Number/Rhyme System: The Number/Rhyme technique is a very simple way of remembering lists of items in a specific order. It is an example of a peg system - i.e. a system whereby facts are 'pegged' to known sequences of cues (here the numbers 1 – 10). This ensures that no facts are forgotten (because gaps in information are immediately obvious), and that the starting images of the mnemonic visualizations are well known.
Incidentally, the Major System, while requiring significant study and practice (both of which benefit many cognitive abilities simultaneously -- no waste here!) is undoubtedly the best. It is worthy of a dedicated article all its own, and we shall see about doing that. I would strongly advise that you invest some time (for an exceptional ROI) in Mastering The Major Memory Mnemonic Technique. I have personally witnessed some amazing feats performed by persons using it.
