This is more of me trying to understand how people imagine things, as I almost certainly have Aphantasia and didn’t realize until recently… If this is against community rules, please do let me know.
The original thought experiment was from the Aphantasia subreddit. Link: https://www.reddit.com/r/Aphantasia/comments/g1e6bl/ball_on_a_table_visualization_experiment_2/
Thought experiment begins below.
Try this: Visualise (picture, imagine, whatever you want to call it) a ball on a table. Now imagine someone walks up to the table, and gives the ball a push. What happens to the ball?
Once you're done with the above, click to review the test questions:
- What color was the ball?
- What gender was the person that pushed the ball?
- What did they look like?
- What size is the ball? Like a marble, or a baseball, or a basketball, or something else?
- What about the table, what shape was it? What is it made of?
And now the important question: Did you already know, or did you have to choose a color/gender/size, etc. after being asked these questions?
I don’t have a minds eye for something to fade from, so that question doesn’t really make sense to me. I have my eyes and then when I close my eyes it’s either black or eyelid colored, nothing else, and I’m super unclear what seeing things in your mind is supposed to be like. Tho I do have super-vivid visual dreams these days (which did not happen until my late 20s, but aren’t at all uncommon for people with aphantasia) and because I only have open-eye sight and these dreams that seem totally real, I frequently have to ask people if things actually happened. It’s very disconcerting, but my understanding is that dreams are not really the same as waking minds eye anyway.
Rather than a visual representation, I’ll have a verbal description ready as soon as I see an item. So for the ball example, I’d know the ball is “small, about the size of a plum, solid pink somewhere between neon and intense salmon, smooth matte texture, looks like it might be foam”. It probably serves the same function as a visual representation, although perhaps with a bit more required specificity. I don’t really describe things to myself unless I need to, though, so I guess my thinking is sort of abstract. I know the traits something has, and can recall them, but typically don’t explicitly list them unless I’m describing for someone else.
One perk of this is I’m great at describing things I’ve seen or made up, a downside is I’m terrible when people describe things to me. Since I’ve never seen the thing being described, it is a super arbitrary list of usually non-specific features and I don’t care at all. I skip clothing descriptions in books, for example. Don’t care. But when I describe things, even made up things, I’ll run through a list of the features it needs as a minimum to be the object for my mind, which is usually vivid detail for others, as the ball example above.
Idk if I see things differently eyes-open, I don’t really think so, but that’s always been a curiosity of mine since there’s literally no way to know what other people see. I have mild impairments as a result of not being able to visualize, like I’m largely face blind - I have to pick out specific features and traits and use the combination as identifiers. I get a ton of false positives, and almost everyone “feels familiar”. Beyond that, I’m pretty sensitive to colors and patterns. Idk.
But the -way- you ask that first question makes me curious; If you close your eyes and intentionally picture something other than the ball, would you then be unable to tell me what color it was in your example? Do you, personally, require the visual representation to “know” the object?
It’s hard to describe, but it’s not replacing your eyesight. If I close my eyes I see black, or if there’s some bright light I see red. But, it’s like there’s another visual channel going into your brain other than the one from your eyes. Most of the time, that channel is either off, or it’s drowned out by the actual visual information which is so much more dominant. But, if your eyes are closed the fact there’s no real information coming on the “real” visual channel means you’re able to notice what the “virtual” visual channel is showing.
It’s sometimes described as your “mind’s eye”, but for me, at least, it’s not really like another eye because it’s not detailed enough for that, but it’s still as if there’s an additional visual stream of information that goes from my memory to the visual processing part of my brain. For me, it’s blurry and lacking in detail. It would be like using a slightly out of focus projector on a white wall in a well lit room. There are shapes and colours there, but they’re hard to see. But, like an image from an out-of-focus projector, if you try harder you can make out more of what it’s showing, and if you reduce other visual stimulus (like turn off the lights) you can notice more.
Does this happen instantaneously for you? If I tried to come up with a description like that it would take several seconds, whether I’m doing it while actually actively looking at the object, or with my eyes closed working based on a memory of the image my eyes saw.
Something real, or something I’m inventing with my imagination?
Like, translate the image to a word? I can tell you a word, but the metal image will come first. I think I do need the visual representation to know the object. Like, if someone gives me a description of something, I’ll build a mental image based on that description. If someone asked me to describe it later, I’d probably use different words because I’d be going based on the image not on remembering the words.
In your case, if you have a memory of something that is “small, about the size of a plum, solid pink somewhere between neon and intense salmon, smooth matte texture, looks like it might be foam”, how easy is it for you to change the words you’d use to describe it? Like, say someone asked you to describe it but not to use any words related to living things, could you swap out “plum” and “salmon” without effort? Do you think you’re storing those actual words, or are you storing a concept? For example, if you’re remembering a white rock, is it “rock” you’re remembering, or is it the concept of a rock, which can match similar words like “pebble”, “stone”, etc.?
Also, I wonder how this affects your ability to remember descriptions of things that are not physically possible in our 3d world, like a Klein bottle or a hypercube. I wonder if, for you, there’s no real difference in difficulty remembering the details of a cube vs. a hypercube because you can’t picture either of them. Whereas for me, I can easily remember / picture a cube, but for a hypercube it’s hard because it’s not something I can get a real visual representation of.
