Records Smashed at (Human) Memory Championship 67

Posted by Roblimo from the I-forget-why-this-seemed-so-important dept.
Pika the Mad writes "Wired News has a neat story about the recent U.S.A. National Memory Championship.'The finalists competed in three brand-new recall events that forced them to remember and recite aloud random words, personality characteristics of guests at a fictional tea party and the order of cards in two decks of playing cards, parroting answers in front of a crowd of onlookers, photographers and video cameras.' The winner claims that in the world finals he'll be competing against people who can memorize an entire deck of cards in 30 seconds."

  • Mnemonic Devices (Score:5, Insightful)

    So, when I was younger, we were encouraged to use mnemonic devices [wikipedia.org] (such as "My Very Educated Mother Just Showed Us Nine Planets"). But I've also heard from critics of the process that they just provide more clutter in the scheme of memorizing things.

    I guess I've always thought of them as indexes for remembering things. You're storing more information but the keys are easier for you to remember and they hold within them something meaningful about the data.

    Oddly, though, often the most bizarre mnemonic devices work the best as the Wikipedia article states:
    A curious characteristic of many memory systems is that mnemonic devices work despite being (or possibly because of being) illogical, arbitrary, and artistically flawed. "Roy" is a legitimate first name, but there is no actual surname "Biv" and of course the middle initial "G" is arbitrary. Why is "Roy G. Biv" easy to remember? Medical students never forget the arbitrary nationalities of the Finn and German. Any two of the three months ending in -ember would fit just as euphoniously as September and November in "Thirty days hath...", yet most people can remember the rhyme correctly for a lifetime after having heard it once, and are never troubled by doubts as to which two of the -ember months have thirty days. A bizarre arbitrary association may stick in the mind better than a logical one.
    For an article with a little more information, check out the NYTimes coverage [nytimes.com].

    Unfortunately, the Wired article only gives us one line sentences from the contestants like:
    "It really helps us a lot in school," she [Erin Luley] said.
    "(Media presence) makes it more nerve-wracking," said finalist Chester Santos from San Francisco.
    "I really did not expect to win," Foer said. "I thought maybe I'd crack the top five."
    Wired, that is pure journalistic gold. Perhaps you'd like to rail them with another question like, "What do you like to do for fun with your friends?"

    I'm sure it helps you in school, what I want to know is how in the hell do you do that? Does anyone on Slashdot know if people who win these competitions actually use mnemonic devices or are they just gifted savants?

      One of the memory techniques I've seen used before for learning a set of random objects was to place them in a common thing, such as going to work in the morning. This also has the advantage of being able to recall in sequence. For example, say the first four random items were an alarm clock, a banana, a mouse (squeeky type, not computer type), and a spoon, you might remember something like:

      'I woke up to my Alarm Clock, which also had a banana on top, which was weird. Sitting up in my bed, I saw a mouse hanging from the end of my bed. I grabbed a spoon to try remove it...'

      Obviously depending on how much you have to remember and what you have to remember the amout of extra story can be shortend to nearly the key items, but as long as you can remember the story in whole, there's little to stop you from realling out a list of items.

      When I had my dyslexia test done, one of the tests there was to listen to a set of numbers, and wait 10 seconds, then repeate them. I then also had to do it again in reverse with a diffrent set of numbers; the number of digits getting longer with each try. The way I managed to do well in it was to see the numbers in front of me, as if they were neon signs, and then make them dissapear when I had said them. This also allowed me to read them off in any order. Normally the sweetspot for recall is 7, plus or minus two items. I managed to make it to 11 digits in order, 9 in reverse, which is fairly good.

      I would wager that people who learn sequences of things would have techniques similar to this.

      There is an article in this month's Discover about it. It doesn't appear to be online.

      For the cards, for example, each card is associated with three things: a subject, a verb, and a direct object, I believe. You memorize a deck of cards by getting 3 cards at a time, and combining the subject for the first, verb of the second, and direct object of the third into a triplet. The actions and objects don't need to make senes; they just need to be memorable to you.

I met one woman who gift was equal to those described in the article. She had no training and simply had the gift. I have an above average memory that serves me well but I find the majority of people become bored when I start to itemize particulars. My parents and sibling smile indulgently at me then carry on a conversation roundly ignoring my detailing.

      I've studied various mnemonic methods. The ancient greeks used an empty stadium as a mnemonic device then would 'seat' items to be remembered in the stadium seats.

    • Interesting stuff.

      Maybe the reason arbitrary devices work better is that there's no second-guessing? I'm absolutely certain that "30 days has September". So much of what we learn is uncertain, or has exceptions. When you can succinctly file away a piece of information you can be sure will always be valid, maybe the brain is better able to "paste" it, without having to add mechanisms for "unpasting" it if future information invalidates it.

      This is from a mnemonic for the 12 cranial nerves (Olfactory, Optic, Oculomotor, Trochlear, Trigeminal, Abducens, Facial, Auditory, Glossopharyngeal, Vagus, Spinal Accessory, Hypoglossal). The standard mnemonic is:
