If you've dreamed of a video game, or you know where things are in your bedroom without looking, or you can draw something, you're probably using visual memory, even if it's not overly detailed. You can probably train yourself to recall more detail if you observe things more closely. Remember the brain is great at compressing - there's no shame in remembering the important parts instead of just a raw photograph.

I certainly don't remember things photographically, but if I memorize a piece of music from a printed version, for example, for a while I'll remember roughly where on the page I would be at any point. But after practicing from memory without the printed version, this spatial memory will fade away.

Wow. My experience is drastically different than yours.

I've almost always thought of things through mental imagery. It comes naturally to me (which really helped in calculus 3, haha). I can say that with confidence.

Thanks for the link. I wonder how many non-visualizers are out there, too.

Sounds wonderful. The odd thing is that I can imagine what it would be like to have the sort of visual imagination that would be helpful in calculus.

Unfortunately it turns out that imagined imagination is worthless for calculus.

Haha. Imagine-ception.

Reminds me how there's apparently a decently-sized part of the population that doesn't intuitively know left and right. I wouldn't have believed it much if I didn't meet someone with the issue and someone else who claims their wife has it.

I've always had problems immediately referring to left or right. As a kid I had to recall which hand I used for the pledge of allegiance to remember which side was right vs left. To this day it takes me a couple of seconds of thought to pull it out when my mind is not already primed for it.

Reminds me of people with dyslexia. I wonder if the two are related.

I have a well developed spatial sense, but am very weak visually. When I try to visualize, the best I get is impressions of abstract glow-y lines that fade away quickly. I also tried to develop mental visualization but to little effect (I did have a vivid dream once. Only once, though.)

This perfectly describes me. Interestingly enough I attribute my great mathematical ability to my ability to "visualize" problems, although I don't literally see objects in my mind's eye. Its almost like my logical circuitry is co-oping my visual processing circuitry to solve abstract logical problems. So while I'm thinking of a problem there is a visual aspect to thought, but its nothing concrete enough that I could, say, draw on paper.

So you can't see the matrix? Take the red pill (No, that's not Modafil painted red) Neo.

On a more serious note, when do you understand something? For me, it is when I can visualize how the parts of the function interact with each other, for example for Summation, how many little functions (those functions are visual images too) in a long finite line stack on top of each other and create a large something, that might get fed into something else.

> Its almost like my logical circuitry is co-oping my visual processing circuitry to solve abstract logical problems.

Wetware CUDA, nice.

Think how hard it is for visual thinkers to produce one-dimensional text of their two or multidimensional ideas. They see all the relations between things directly but it is hard to express in text. It's not always a blessing.

It has been intermittently amazing to me that I not only get by but am even considered intelligent without what seems (to me) an absolute gift and superpower that most people possess.

The rest of the time it's just obvious that there are tradeoffs, or that it's behaviorally insignificant unless one is off the chart positive on some modality. Would still give anything to picture though.

Just to say you are not alone. Though my internal voice has no accent and does not sound like me. We may well differ in other respects.

I remember the day I asked my English teacher what she was talking about when she described the impact of poetry on your mind...and the expression of pity she showed.

I remember the day I discovered my sister read a novel and imagined a film as she read...this was the first time I was ever jealous of my sister.

They were not good days. People might wonder what I remember. I remember my thoughts-emotions of the moment. So when I say I remember my teacher's expression I remember my thoughts-feelings about the fact that I could see her pity.

However, there are major advantages especially as life as gone on. It seems to have taken me longer to get the hang of life as I have had to develop alternative ways of doing things that are often not as efficient as the visual method. But that has given me a powerful originality of thought and approach that I can increasingly use to my advantage now I am no longer undermined by the basics of life.

Thank you for this. Even though I consider myself pretty average now you've made me feel like I have some secret power. It helps a lot when I visualize things. Also, writing ideas out in a narrative also helps. So, I guess I can do both. Genius Here!!! (Standing up, wide eyed, looking proud with an idiotic smile)

p.s. I don't actually believe that you cannot visualize images. Can you draw a stick human figure? Did it pop into your head when I mentioned stick human figure? There you go, you just visualized it.

p.s I guess inability to visualize something could be something similar to dyslexia?

It's frustrating when people suggest I can visualize and just don't know it. The way one thinks is the most first-personally obvious thing in the world, and I've been sore about the way I do it since I was in elementary school wanting to imagine strawberries to count with.

Despite the literature I never accuse visualizers of the reverse (ie that you only think you have mental images), but when I do challenge incredulous friends about their phenomenology some discover it's actually much less pictoral than they'd believed: eg, "imagine a tiger, how many stripes?" or "imagine an ant crawling across a checkered picnic table toward a jar of grape jelly, what color square is it on now? what about now?" or "imagine a 3x3 word matrix whose rows read 'too', 'aid', 'ole' -- read the column words straight off without sounding out or going letter by letter". Granted, others can do these with an ease that amazes me.

"Can you draw a stick human figure? Did it pop into your head when I mentioned stick human figure? There you go, you just visualized it."

Yes I can draw a stick figure. I'm not an idiot, and nothing pops into my head other than the sound of the word and some xkcd affect.

Meanwhile, it astounds me that a single picture can pop into your head: how do you know what position to put the stick figure in -- akimbo, Thinker? Imagine a flower -- ok, which, a rose or a marigold? Do you decide or does it just happen? How many different flowers can you visualize, and how quickly? Do they appear embedded in soil or just floating free? How many different varieties can you see at once? What prevents you from seeing more?

Re: dyslexia -- I drew this link too, as I have very mild dyslexia. My father is profoundly dyslexic but claims vivid imagery.

> "imagine a tiger, how many stripes?"

Well, for me imagining a tiger is basically recalling what it's like to look at a tiger (or picture of a tiger). I can have a photo of a tiger right in front of me, and know it's a tiger, yet not know how many stripes it has without counting. I might also not notice how the back paws look if I'm focusing on the front paws. Same thing when it's in my head (except less consistent, since it's just a memory).

> how do you know what position to put the stick figure in -- akimbo, Thinker?

This is no different from other senses. If I tell you to imagine the smell of soup, do you smell minestrone or pho? (Have you cooked those dishes? When you smell soup, can you tell what spices are in it?) If I tell you to imagine the sound of a violin, is it a six year old scratching away or Yehudi Menuhin playing a Beethoven concerto? (Depending on your musical training/listening habits, you may be able to imagine a concerto all the way through, or maybe just fragments of it?)

The interesting thing is, at one point I thought, like you, that I couldn't think visually. I tried practicing it, and either that worked or I adjusted my definition of visual thinking (or a bit of both), because I definitely consider myself at least partly a visual thinker now, and it's difficult to imagine it any other way. I've noticed that my visualization ability is sensitive to how much sleep I get though.

If you can think of chocolate, but not how it tastes, how it feels in your mouth, what a square looks like, what sound it makes when you bite into it ... maybe you just need to pay more attention the next time you eat chocolate :) And my ability to imagine other things - like music or food - depends strongly on how much time I spend on such things.

I appreciate the vividness of your minestrone, pho and chocolate examples, but I can't seem to do what you describe. I can't imagine smells or tastes -- both are as foreign as the visual modality (though much less missed). When I read the example I hear the words "imagine the smell of soup" I simply hear (in my head) my voice say the word 'soup', then, when asked to elaborate 'minestrone - pho' -- more words. I can sit with my eyes closed for the rest of the afternoon but the thoughts go no deeper, or I can silently direct my attention at the memory of the last auditory image, or repeat 'pho' in my head, or say something like 'curly noodles, light broth, deep green basil' and list off favorite attributes of pho, but it's low bandwidth audio and not cumulative in the way my dreamed pictorial representations are.

With respect to music, I can occasionally imagine a few concertos most of the way through in rich detail, but more often just in detailed fragments. I don't seem to have much control over how it sounds, what it is (usually Beethoven or BWV 1004), or when I can do it. I listen to a hundred contemporary songs for every one classical and I can't so much as summon the tunes or lyrics of any of them. Truth be told I don't listen to much music as I find it impossible to think while doing so, as if it's all on the same metaphorical channel.

edit: on the tiger, I'm not expecting the person to solve the speckled hen problem. People with stable mental images can count the stripes off the picture, none should simply "know" how many are there. Some believe (until confronted with such a challenge) they think in fuller, richer pictures than they actually do.

It sounds :-) like you may have more sensory representation than me - as you have some auditory representations.

I remember emotions but I don't remember my bodily sensations.

With regard visual images (in response to words) it is like part of my brain sees it but I have no conscious access.

However, I have had one intense conscious dream where in that dream at least I had full sensory representation in every dimension. It was wonderful! I remember playing with my dreamscape and transforming things visually before I woke up...and so I - at least - have some idea of what being able to visualise means to others

Are you saying you can't hallucinataste chocolate? The soft melting of a piece of milka, the soft stickiness of your tongue against your teeth, the feeling in your throat, and of course, the sweet cacao taste on your tongue? I don't know why, but if I think really hard about it, I can actually vividly imagine the experience of eating chocolate, but I can't have any other flavour in my mouth at that time. I can mix it with other imaginary flavours though, which is why i roughly know how a sauerkraut hot dog tastes despite not having eaten one ever. (Sauerkraut ufm wurstbrötl? Sapperlot no ma!)

One really curious thing that happens to me though is that when I smoke and smoke gets into my nose, the burn in my nose might trigger one of my taste memories, leading to me tasting some random thing in my mouth, from Apple Juice to seared steak. I do get some weird stares though when I suddenly say that taste out loud.

I'm not a freaking computer.

You might as well tell me to add 182748+37638373 in my head. The reason I cannot do this is that it requires short term memory and I don't have much of it. I can only remember four, five, maybe even six number in a row at a time in short term memory. You giving me a bunch of instructions to visualize exceeds my short term memory so I cannot do it. In other words, I'm not a computer, neither are you.

>>>Meanwhile, it astounds me that a single picture can pop into your head: how do you know what position to put the stick figure in.

Well if nothing pops into your head then I guess you really cannot visualize. The stick figure is usually standing up straight.
