Secrets of a Memory Champion

Hugh Pickens writes writes "We've all heard of people who claim to have 'photographic memories.' Now Joshua Foer writes in the NY Times magazine (reg. may be required) that a 'skilled memory' can be acquired and proves it by explaining how he trained his brain to became a world-class memory athlete winning first place in the speed cards competition last year at the USA Memory Championship by memorizing a deck of cards in one minute forty seconds. According to Foer, memory training is a lost art that dates from antiquity. 'Today we have books, photographs, computers and an entire superstructure of external devices to help us store our memories outside our brains, but it wasn't so long ago that culture depended on individual memories,' writes Foer. 'It was considered a form of character-building, a way of developing the cardinal virtue of prudence and, by extension, ethics.' Foer says that the secret to supermemory is a system of training and discipline that works by creating 'memory palaces' on the fly filled with lavish images, painting a scene in the mind so unlike any other it cannot be forgotten. 'Photographic memory is a detestable myth. Doesn't exist. In fact, my memory is quite average,' concludes Ed Cooke who recently invented a code that allows him to convert every number from 0 to 999,999,999 into a unique image that he can then deposit in a memory palace. 'What you have to understand is that even average memories are remarkably powerful if used properly.'"

      I believe I have a photographic memory, although I couldn't be sure, because I haven't had a different memory to be able to tell the difference.

      What I can say with absolute certainty is that I can recall certain scenes which I have seen and somewhat visualise an image in my mind of that scene. I can't recall detail- I couldn't look at a book page and recall every word on the page, but I can walk down a street, and think back to that scene and say "Yeah, there was a red Ford Mondeo turning left, I was on the left hand footpath, there was a coop shop to my left, 1ft by 1ft square gray paving slabs, a girl crossing the road with a grey top and a pink pushchair, a blue Renault Clio parked up in front of me".

      I don't really have any control over what I remember in this manner or what I can recall- I cannot recall what my dinner looked like for example but I know I had a chips (UK chips), beans and sausages. I can however randomly remember a scene from when I was driving to work yesterday morning- in this scene I was just passing the road sign for the village I was passing through to my left, I was coming up to the brow of a hill with a white van coming towards me on the other side with it's lights on. and a junction to the right in front of the van leading up a steep hill. It was just before the sun was really starting to rise so my car lights were on, the sky was a dark blue, slightly lighter towards the visible horizon. Why did I remember this scene? I've no idea.

      I do find I can force myself to recall a random photographic memory, which I hadn't even realised I'd remembered. I do sometimes find I think of one randomly when I'm bored. I do find I can force myself to remember a scene to an extent. The image I described just now for example I remember randomly recalling at work yesterday whilst MSVC was compiling, and I was able to recall it again now at will for this example. I do think those things I passively remember in this photographic way are probably related to stress levels- if I do remember a random image it's likely that a lot was going on in it, or that someone was driving like an idiot and nearly crashing into me- and yes, here's one that'll amuse the Slashdot crowd, the goatse image is engraved in my memory and I can, unfortunately recall it at will along with a couple of other pictures I've had the misfortune to see on the internet that I perhaps wish I could un-see, but as I'm neither squeamish nor do I recall recalling those images randomly at any point it's thankfully not a big deal.

      It's certainly not just a case of recalling what was in the scene but being able to visualise it and then pull information from that visualisation in my mind. This is why I presume I have a photographic memory.

      Whether someone can train themselves in this way I've no idea, it's just something that's always been naturally possible to me.

      Spatial/visual memory is in average person much more powerful then conceptual memory.
      All memory is association, but if you compare how efficient you are in remembering, let's say a rather complicated path through a bigger park compared to remembering let's say remembering 8 3-digit numbers, spatial memory easily wins by order of magnitude in an average person (people who have great visual memory or great audio memory might complicate the analysis, so treat those as special cases).
      Spatial memory is so good that we expect very much of it, that's why labyrinths are interesting and also that is why when it you get lost or can not find a certain place you forget how good your spatial memory is: most of the time you know exactly where you are, you know how to get to most places you know and most importantly you retain this information without effort for years and years (think about cities you used to live in, airports, houses, etc...).
      Using these existing memories is referred to as 'memory palace' (palaces are usually also well structured with many separate spaces) - now, the point is that since all memory is association, you can use existing memory structures (rooms, halls, stairways, etc) to store new information by using your imagination and associating new info with existing one.
      Besides the spatial, we are also quite good in remembering how something happened - films, theatre, etc comes to mind. So you take something that we are not so good at and turn it into something we are good at: you use, for example well known room to put the objects that you would like to remember in places that you have a good memory with. Objects can be a coding system for cards, numbers or other less visual information that you would like to store.

      True, except I don't consider spatial memory and image memory to be the same.

      True. They are not the same, but there is overlap. Topological rarely goes without image memory. Images are encoded, yes, and photographic memory is really rare (http://www.youtube.com/watch?v=jVqRT_kCOLI) and probably there's a reason.

      First of all spatial memory provides a constant stream of clues. That is you have a current view that you can use as a key to the next assiocation, if you try to remember an image you usually have a one clue -> all details relation. You can fix that by making strings of associations, but that is the memory tricks we are talking about.

      Memory is association. What you call tricks are just using conscious efforts to reinforce associations.
      Furthermore, memory can be improved even without conscious meddling in encoding system; one of the standard exercises during drawing classes is to observe different parts of face - for example you spend a week observing people's noses. All the time. Everywhere you go. Result: your perception and memory increases - it is like the compression algorithms that help you encode and associate a given detail (nose, ears, eyes, etc..) improves.
      Also, the image is not a single, full detail clue in terms of experience on the level of neuron excitation - your eyes always provide the stream, even looking at the still image - full resolution of your eye can only be achieved on a very limited FOV, that's why you move your eyes while you read this text or while you look at the painting, etc...
      It is the encoding system (and hardware) that your brain uses that distinguish the image retention capabilities - be it naturally or consciously trained.

      I consider remembering numbers and images equally hard because both has a single context to a lot of details relationship, and to remember many of the details you need all kinds of tricks.

      People have different difficulty of remembering certain details, some remember dates, some smells, some people, some emotions, so when having to improve your memory you would usually use something that you are natural good at remembering.

      Again true, however, I repeat, spatial (in a sense of topological+image) memory is particularly good in humans. Also, most faces (image) you remember from just one meeting (names are the problem; reinforcing association is useful in remembering the name; but this remembering faces is understandable - we have specialised hardware for that, see http://www.ted.com/talks/vilayanur_ramachandran_on_your_mind.html on what happens when it breaks). Most locations you remember extremely well with quite a lot of detail. Stephen might remember more, but is that optimal? So you do abstract the images, unless there are particularly important to what you do or what you like; at the same time you do remember distinguishing factors: for example you might still remember the exact way to your childhood school, a neighbourhood where you lived ten years ago, student dorm, streets in various cities that you walked and that is not pure abstract topological graph; memory contains enough image detail for recognition (compression algorithms are normally optimised for recognition, not necessarily reconstruction; http://www.youtube.com/watch?v=Ipomu0MLFaI).

      I'm currently learning Italian. When a word doesn't come from a Latin base, linking it to its English analogue is tricky so it's simpler to make up some association than it is to remember the word. The Italian for "where" is "dove" (which is pronounced a little like "duvet"). Where's the dove? Under the duvet. I can't forget it or get it confused with when, why, how or who. When an Italian wants me to say "Where", I link dove, duvet and the image/sound of my girlfriend saying that word on the phone one day. (Still doesn't mean I can pronounce it properly, though!)

I could probably read out every line from the largest AUTOEXEC.BAT and CONFIG.SYS that I ever had, too.

      I can do the balcony scene because we were told to memorise it for English class and we would be performing it in front of the class the next day. I still know every word. I can remember pi because I went through a phase of writing computer programs to calculate it and it was simpler to have it stuck in my mind to see how fast they converged. I can do the AUTOEXEC.BAT because I wrote the thing and changed it every day for a year in order to get *anything* to run and ended up with a set of "perfect" configs. I can still remember whole conversations from primary school, and weird things like what my dad said to me on a trip I took when I was 8 and things like that.

      It just matters more which type of learner you are - teachers have been teaching to a certain number of learning styles for DECADES - visual (has to see / imagine something to learn it), tactile (has to play / touch something to learn a principle), auditory (has to hear something to learn it), etc. and any decent teacher knows which of their kids are which style and how best to explain new problems to them.

      The problem I have is that on every "learning styles" quiz that I've ever done I come out as every learning style evenly. So does my brother, who also went to university. That means that mere exposure to something is enough for me to learn it which means I pick up lots of useless information and my memory doesn't get any "special" exercise - it just does it's job and doesn't have to struggle for *anything* that I'm interested in.

It's also why people tend to flinch when people hit their cars.

You'll see instant experts claiming that "BP should have know better than to put blowout preventers using blah blah blah" when if you'd gone to all that people posting in the thread a week before and asked them in person if they knew what a blowout preventer was, the percentage would be pretty close to zero. /. is a pretty highly educated group of folks - I'm sure there are some people that have studied them just 'cause - but certainly not in the numbers that were chiming in here with their opinions after the accident. (Captain Hindsight and all that.)

    *IF* there were true photographic memory, then the prizes at these world memory championships would be scooped up by people that have it. But they're not. They're won by ordinary people with pretty average memories who dedicate their spare time to mastering memory techniques.

    This is an excellent point, but it is worth mentioning that there is a different sense in which some people do have a limited kind of "photographic memory", although I don't believe this justifies the use of the term in the ordinary sense, which applies to an empty set of individuals.

    The case I'm thinking of was discovered in an experiment dealing with visual persistence. The experiment involved look at two images with a stereoscope. Both images were random black-and-white pixels. The idea was that where the images were identical, the viewer would see them as flat in the stereoscope, but if they had regions that differed there would be a 3D effect. The viewer looked at the images with both eyes and then closed one eye. In most people the 3D effect in the mis-matched part of the images (a square in the center, I think) persisted for a second or two. But in a few people it apparently persisted more-or-less indefinitely, suggesting some kind of visual memory that was pixel-level-accurate and relatively long term.

    I haven't read the research in question, so this has all the veracity of "something I heard on the Internet from some guy who heard it from someone else."

    Yeah, you're not kidding. He seems to have remarkable visual cognition. I can't do that. My "mind's eye" is not an eye. If I close my eyes and "picture something" I don't get a picture. The best I can do is think about something which for me is an entirely linguistic process, there is no visual component.

    I mean, try this. Close your eyes and picture an apple. Is it red or green? I get the feeling that some people actually see an apple, and it actually registers as red or green in their brain before the question is even asked. When I try to picture an apple, all I can do is think "apple". If I'm asked what color it is, I don't know because there is no apple, just a generic apple thought.

    So yeah, this is not a technique everyone can do. Some people just don't have visual capabilities like that.

    Perhaps ... but if you had a photographic memory, don't you think you'd have better things to do with your time than bore yourself with memory contests?

    Most of the truly powerful memory systems relying on visual imagination; sadly, not everyone has a powerful visual imagination/memory. Some people can imagine a whole room filled with intricate details, other people have trouble picturing their wife's face after 20 years of being together. The reason people don't understand this is because everyone assumes that they're normal. People with visual imaginations assume that everyone has one, that people who can't use memory places must just be doing it wrong. People without visual imagination assume that no one does, that memory places are an elaborate metaphor or something. I myself have an excellent memory and a powerful imagination, but struggle to retrieve detailed images from memories. I tried for months to apply memory places without making any progress because my brain simply isn't wired that way.

    More than that. I first see a Red Delicious, then a Granny Smith. Now a Yellow Delicious, and my current supermarket's display of apples, including Fujis, Pink Ladys, etc. Prior supermarkets I've been to, including ones from when I was a kid. The smell of fresh apple, the smell of decaying apples by the cross country race course at my middle school. The sights and sounds of the hornets buzzing on those decaying apples, the dread I always felt running past them, hoping the hornets were too drunk to attack. The burning in my lungs at that part of the course. My middle school floor plan. The day I went back to visit old teachers as an adult. Seeing that the Apple ][ computers were on display instead of in use. Apple ][, that's what I see in my mind's eye.

    ...that an Albert Einstein icon is associated with a post about memorizing. Why? Because, when asked why he was looking up his own phone number in the phone book, Einstein said:
