The limitation of this system relative to Tim’s/Tomoyori’s is the up-front time commitment. (Interestingly, this leads to odd errors with perceptual explanations - if Bruce Lee is 42 and Jackie Chan is 98, you might insert 98 where you were supposed to have 42 if you didn’t cement the image in your mind firmly enough.) You can then use the method of loci as Tim described.

That lets you chunk each six-digit number into an image: Maybe 425661 is Bruce Lee (42) sweet-talking (56) a pile of rubies (61). Basically, you associate a character, an action, and an object with each two-digit number. I recently talked to a competitive digit-memorizer (mnemonist?), and according to him, the standard technique among memorizers is something a bit more complicated. Learn to efficiently encode the abstract and the results can be superhuman. Increase your recall capacity by 500% and you can effectively quintuple your lifetime learning capacity. This combination of encoding methods automatically permits you to recall digit strings both forwards and backwards!Įncoding, and improved abstract recall, can be used to learn 500 foreign vocabulary words in a single 12-hour session, increase IQ testing results by 20-30 points, or memorize all of the ticker symbols on the NYSE. And guess what happens if you trace your route backwards, taking into account the order of letters? 0173-118 (509). TIES (10 = TS) where shoes should be in the shoe rack.īy mentally tracing your loci route, you produce (905) 811-3710. A huge MUG (37 = MG) on the kitchen tableĮ. Princess DI (1 = D) sitting on your staircaseĭ. A huge PHOTO (81 = FT) of yourself plastered on your bedroom doorĬ. To memorize the number (905) 811-3710, you could follow this sequence:Ī. Associate your composite images, in appropriate order, with the predetermined locations. Using the path from your bed to the shoe rack as an example, the following locations could serve as placeholders for your composite images: bed, bedroom door, staircase, kitchen table, shoe rack.Ģ. Horizontal sequences are easiest to use: streets, hallways, room perimeters, etc. Choose a familiar route marked intermittently by outstanding features. The loci method uses preselected and familiar locations:ġ. The second step is to take each image, made from 2-6 numbers, and place them in a sequence. Likewise, repeated letters are represented by a single number unless two separate sounds are made: 3230 = MNMS = Minnie Mouse (“nn” represents the single 2). Thus: 8762 = FKSHN = fikshun = fiction (vowels possess no value). Numbers are converted to words by the phonetics (sounds), and spelling is unimportant. If you can then place one such composite image at 20 preselected locations (loci), you will memorize 80 numbers with ease. Using the above conversion table, 8209 could equal “fan” (82) and “soap” (02), thus a fan made of soap. Numbers are encoded as indicated below, and suggestions for remembering the pairings are provided in parentheses:ĥ = L (you have five fingers on your Left hand)Ħ = j, ch, soft g, sh (“J” is a near mirror-image of “6”) (Ex: Jelly, CHips, garaGe, SHoe)ħ = k, hard g, hard c (“7” side-by-side with a mirror image form a sideways “K”) (Ex: Kite, Goat, Cat)Ĩ = f, v, ph (“8” is similar to the lower-case cursive “f”) (Ex: Flame, Vest, graPH)Ġ = z, s, soft c (0 signifies “zero”) (Ex: Zipper, Scarf, iCe) Here are the encoding pairs that Tomoyori used to recall 10,000 numbers without error.

Bear with me - the examples make this simple to use. Numbers are converted to consonants, which are then converted to nouns and images. In this system of encoding, vowels (a, e, i, o, u) have no value, nor do w, h, or y. This introduction to encoding will provide an overview of the consonant system mnemonic, which encodes numbers as consonants of the English language. Using proper encoding, trained subjects can memorize all of the area codes in the United States within a 24-hour period… By encoding abstract data first as letters, then as nouns, one can accurately store and recall hundreds of items (images) both forwards and backwards. The average person can only hold seven or fewer numbers in their working memory at any given time, using vocal repetition as an aid. Hideaki used what I’ll teach you here, whereas my classmate used a phantom abacus like in the above video. The answer is proper encoding, or translation of the abstract to the concrete. If numbers are both abstract and difficult, how did Hideaki Tomoyori of Japan memorize PI to more than 10,000 places? How did my classmate in Tokyo also multiply four-digit numbers in seconds? Numbers, or digit strings, are considered by many mnemonists and cognitive scientists to be the most difficult data to memorize. The spectrum of human memory potential: Daniel “Brainman” Tammet beats blackjack and Japanese schoolchildren become human calculators.
