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'll participate.

The ball is silver colored/metallic, grapefruit size. A man resembling my partner pushed the ball. The table is a plain square wooden shaker-style.

I began imagining as soon as I started reading, with each additional word adding detail in my mind. By the time I got to the questions it was easy to answer them.

I imagined a sort of physics textbook diagram, not real objects. There was no person, only an arrow indicating the applied force on the ball!

[–] [email protected] 12 points 1 day ago (3 children)

That's how I did it too. There is a sphere on a plane. A force is applied to the sphere, parallel to the plane. Neither the sphere nor the plane have a defined color, size, material, etc. Nothing specific pushed the sphere.

My job is often to mathematically model the things people say to me, and in those circumstances thinking like this is correct.

I don't think this way when I daydream, although the visual components of my daydreams are more like the feelings I get when I look at something than like concrete mental pictures.

Colorless ball, around the size of a tennis ball on a colorless round table. Person was colorless, genderless, and generally without any distinctive features.

What is my diagnosis?

[–] [email protected] 3 points 22 hours ago (1 children)

Yep pretty much what I got

I imagined it in a cartoon-ish fashion, so I think I can actually draw it out.

drawing

  • Red ball
  • Male
  • Like Google's default profile picture, without facial features, except he's in gray and has a neck
  • My single hand can surround more than half of it in a cross section view, so about 12cm in diameter
  • Rectangular table, about 5:2, I didn't imagine the material, but it's plain brown, so I guess wood?

Additionally, the ball rolls parallel to the long edge of the table, and falls off the short edge. The person also have legs.

I already had these in my mind before being asked.

[–] [email protected] 5 points 23 hours ago* (last edited 23 hours ago) (1 children)

My brother in Christ you have described almost the exact same specs I visualized. The only difference is in the level of resolution of my "scene." And by that, I mean essentially I did a few more render passes in my head to anchor everything you've written within a sort of Impressionistic, highly softened, out-of-focus backdrop. I saw hints of shadowy cabinets, the concept of a darkened kitchen out of sight. The shape and finger placement of my slightly more textured, clothed yet featureless male. The gray-brown feeling of a floor below, a dark white ceiling above, and the faded glow of sunlight through an unseen dining room window grazing one end of that oaken table.

But the basics ... They're the same, and before being asked to recall them. Damn.

[–] [email protected] 2 points 23 hours ago

I mean, people will imagine a similar thing when asked to imagine something specific. At the end of the day there's just so many ways to imagine someone pushing a ball off a table.

[–] [email protected] 3 points 23 hours ago

More or less but person didn't have gender because that wasn't relevant to the subject which was the rolling ball. Ball also bounced a few times when hitting the floor.

[–] [email protected] 6 points 1 day ago (6 children)
  • What happens to the ball? It rolls of the side of the table.
  • Color: I didn't imagine a specific color
  • Gender: I didn't imagine a specific gender. Most of the person was "out of the frame"
  • What did they look like: Again, most of the person was out of the frame, they were just kind of a gray silhouette
  • What size was the ball? Like a dodgeball I guess?
  • What about the table? Very minimalist square table made up of five rectangular prisms (the surface and four legs). No specific material, uniform texture. I imagined everything in isometric perspective.

This is what I recall from my first time imagining the scenario, I'd have to imagine some more if I wanted to give specific answers.

With all due respect, I don't believe aphantasia is a real thing. The way people imagine things is so varied, weird, strange, and unique that I don't think it makes sense assigning labels. Different people will give varying levels of detail to different parts of their imagination based on their past experiences and knowledge.If you ask someone to imagine a chessboard, someone who plays chess might imagine a specific opening or valid board state, while someone who doesn't might just have a vague blob of chess pieces on a board.

Even with your ball on a table experiment, the experiences people have had throughout the day may give more or less detail to the imagined scenario. I'm fairly certain that the reason I imagined everything so abstractly is because recently I found an artwork with a similar minimalist isometric style that I liked a lot, so it's kind of floating around in my subconsciousness and affecting how I imagine things.

Blue rubbery ball with small dents in it like for a dog toy.

Pushed by a man in a suit with brown hair but face of Olaf Scholz because I did read a news about him prior.

Ball had a diameter somewhat smaller than a tennis ball but bigger than a golf ball.

White table with very flat plastic top, like in a students learning room. Because I automatically associated this as some kind of experiment which I often did at school.

I could feel the table I rested on while watching the man push the ball to fall of the table.

I have a high level of imagination and work creatively all day in my free time, be it doing art or playing creative games. But this never increased in a way, I remember being able to create these same quality images in my head since I was able to read as small child.

[–] [email protected] 1 points 17 hours ago

The ball was a blue pool ball, on a wooden table that I can't describe because I suck at describing things (but I do have a visual of it). I didn't even imagine the person beyond the hand coming up to push it off.

The ball color might have been decided on the moment I read the question, I'm not sure whether it was part of my image before that. Person is still nondescript even after trying to "zoom out". I just can't seem to come up with it.

[–] [email protected] 6 points 1 day ago (1 children)

What does it mean if the first time I pictured the ball being pushed I noticed it was sliding instead of rolling and corrected it

[–] [email protected] 2 points 1 day ago

Yeah I had a similar struggle. I don't think I've been so caught off guard by a visualization.

[–] [email protected] 1 points 17 hours ago* (last edited 17 hours ago)

Ping pong ball on a circular wooden table. It took me a second to decide the shape. I can see the boards but I only focused on the tabletop and the ball so the environment wasn't defined. The person pushing the ball wasn't well-defined either. No shadows on the ball. If I go back and re-visualize it with more effort I can imagine the details (environment and person), but by default I don't. I steal the environment from my memories by default but can imagine something else if I try. Shadows and light are very hard to get right even when trying, unless I'm only imagining one object or purposely thinking of something specific (ie light reflecting through a glass).

[–] [email protected] 20 points 1 day ago* (last edited 1 day ago) (3 children)

spoilerInteresting, on the first sentence I actually thought of many different sizes and shapes for the ball, then realized I'd have to pick one before moving on to the next part, so it was kind of a conscious decision. I ended up with a simple grey anti-stress ball. But the table was always the same, light brown wood. All focus is on the ball so the person is just a silhouette partly out of camera but the hand is white and wearing a black sleeve. I only chose what the person looked like after the questions based on what felt right for the initial visualization, like panning out the camera.

There's another question though. Would your mind get into all this trouble if you didn't know there would be questions coming?

Under aphantasia, Wikipedia has a long list of famous people who have or had it.

How can these guys have aphantasia?

[–] [email protected] 1 points 17 hours ago (1 children)

I don't think I'm clear on what you're asking? Is it that you're confused as to how a person can be a fantasy or sci-fi author with aphantasia?

If that is what you're asking, then as someone with aphantasia, I likely can't explain how that can happen anymore than people who don't have aphantasia (like you, I presume) could explain to me what it's like to visualise things. What I can say is that whilst I don't tend to read fiction much nowadays, I used to be an avid reader of both sci-fi and fantasy. I've found that immersive writing tends to involve descriptions that involve more senses than just sight, and also that the environment can be effectively described through how characters interact within the world. A well described world might be easy to visualise, but I don't think that being able to visualise things is necessary for producing that.

Not least of all because all the best writers also read a lot, and fiction is predominantly written by and for people who don't have aphantasia. Through this, I would expect that an author with aphantasia would become proficient in writing that facilitates readers' visual imaginations, even if they themselves didn't engage with fiction in that manner.

[–] [email protected] 1 points 17 hours ago (2 children)

But how would someone with aphantasia be able to describe a fictional world well?

By definition they would need to describe something that they can't visualise

[–] [email protected] 1 points 16 hours ago

I'm not sure what definition you're referring to, but I don't see any reason why visualisation is necessary.

By analogy, I used to have a friend who was born with no sense of smell. This also greatly impacted his sense of taste. Despite this, he was an excellent chef. I once asked him about this apparent contradiction and he explained that because he knew this was something he lacked (it was discovered when he was a teenager), he had put extra work into learning how. He was very reliant on recipes at the beginning, because that was more formulaic and easier to iteratively improve. He most struggled with fresh ingredients that require some level of dynamic response from the cook (onions become stronger tasting as they get older, for example), but he said he'd gotten pretty good at gauging this through other means, like texture or colour or vegetables, and finding other ways of avoiding that problem (such as using tinned tomatoes, for consistency).

I found it fascinating that his deficits in taste/smell actually led to him being an above average cook due to him targeting it for improvement— I met him at university, where many of my peers were useless at cooking for themselves at first. To this, he commented that it wasn't just the extra effort, but the very manner in which he practiced; obviously he couldn't rely on himself to test how well he'd done, so he had to recruit friends and family to help give feedback, which meant he was exposed to a wide variety of preferences and ways of understanding flavour. He also highlighted that the sampling bias in my surprise — that all the times that he had cooked for me were things he had loads of experience cooking with and so he could work from knowledge about what works. Most people who had as much cooking skill and experience as he had would be way more able to experiment with new ingredients or cuisines, whereas my friend had to stick to what he knew worked.

I wonder whether aphantasic authors might feel similar to my friend — like they're operating from recipe books, relying on formulae and methods that they know work.

Why do you think you need to visualize something to imagine or describe it? It's just a wholly different way of thinking.

[–] [email protected] 18 points 1 day ago* (last edited 1 day ago) (2 children)

I can visualize things in my mind, but it's not... Clear? Like it's not as vivid as seeing with my actual eyes. It's like seeing images as reflections on tinted glass. Dark, murky. Muted colors. There is also an emphasis with text. I think of a ball. I imagine a red ball with the text "Ball" above or below it.

In the scenario given, I see a dark image of a red ball on a wooden table. A hand not attached to a person pushes the ball. The ball rolls across the table and falls off. There is text below describing the situation.

[–] [email protected] 2 points 23 hours ago

For me it's kinda unfocused, like I can imagine a ball on a table and someone giving it a push.

Only after I force myself to think a bit harder about it, I get a regular square wooden table in a kitchen-esque room, with a silver pinball on it, while a guy approaches it and gives it a small push, at the same time, the post didn't ask me to imagine the ball falling off the table, so the ball barely rolls at all.

[–] [email protected] 10 points 1 day ago (3 children)

It's important to know if the text was displayed in comic sans or not.

[–] [email protected] 7 points 1 day ago

Times New Roman.

What happens to the ball? It rolls slowly off the table, and bounces a few times away from the table before coming to a stop.

What color was the ball? Blue

What gender was the person that pushed the ball? Male

What did they look like? Tall, average build, short brown hair with facial hair, maybe mid-30s, gray shirt, brown pants

What size is the ball? Like a marble, or a baseball, or a basketball, or something else? A bit smaller than a basketball, like a ball for kids or a handball.

What about the table, what shape was it? What is it made of? Round, wood, but like the cheap laminate kind with plastic edging. Metal legs. Like a cheap table you'd see in a school or office.

I feel like I imagined a lot more detail than others. The questions were really easy for me to answer, and like a lot of unnecessary details came to mind. The guy pushed the ball because he was asked to, and he didn't know why he was there. Probably the schizophrenia.

[–] [email protected] 4 points 1 day ago

Weird. I’ve been thinking a lot about my aphantasia recently.

The closest I can describe what I imagined, was the feeling that those things happened.

For example. That vibe you get when you feel someone is just behind you. You can’t see them, but you know it. If I imagine someone behind me, I get the same uncomfortable feeling and an urge to look behind me.

[–] [email protected] 7 points 1 day ago

I can imagine it in the sense that I can understand what happens. There is nothing visual at all for me. My assumption was that it was roughly-tennis-ball-sized absent any other info, but it wasn't even a person, just a hand pushing a ball (and again, just the idea and nothing visual) as no other info is relevant.

[–] [email protected] 4 points 1 day ago

I have hyperphantasia according to these kinds of tests (although I am not sure how accurate they are). In any case, the ball was white with a green glow it was smooth and looked like plastic but no seams where the halves were joined, male, like a large blue bird I saw in a cartoon, a bit larger than a baseball, the table was a very long rectangle shape. It was also white. The ball was pushed very hard from one end of the table to the other and then it bounced on the wall, the floor and the ceiling. The room was a bit small, with only a very small window rectangular window. It was black behind the window. The room was also rectangle shaped, with concrete grey walls. It was a bit dark, but there was some artificial light from a lamp. The bird acted very cartoonish when pushing the ball. I think that is all.

[–] [email protected] 4 points 1 day ago

Maybe I am broken by all the physics thought experiments, but my image was very bare-bones

spoiler


I imagined a small ball (roughly of size of my fist) but only an outline, no features, I did not imagine practically anything about person - just a force (imagined impulse was parallel to table plane) - I did imagine ball rolling (considered forward rolling, as opposed to impulse on center of mass (which in a frictionless situation would make it just linearly translate, or backspin) and falling from the table after a few seconds

[–] [email protected] 6 points 1 day ago* (last edited 1 day ago) (5 children)

Oh my! I didn't know what to expect, and I have to say... I was quite surprised by some of your answers. Also confirmed to me that I am definitely not normal

Not many replies that are indicative of Aphantasia so... here goes nothing. I tried really hard at this okay

spoiler

I don't "see" see anything when I close my eyes. I can create a very vague concept of a ball, a table, and... kind of a person in my head, but I don't actually see the scene, I used to think when people say imagining things they were just making a metaphor. Things get really funk from here... But the overall schema feels more like one of those badly drawn scenes from the hit visual novel Slay the Princess. And yes I imagined it in 2D for some reason

  • Color: the ball doesn't have a color
  • Gender: it wasn't even a real person; it seems like a silhouette of the hand and back of a person
  • Looks: As I said, the person isn't even facing me
  • Size: No idea; in retrospect it's fairly large compared to the table (diameter probably 1/2-1/3 of table?), but the table is also an abstract concept so...
  • Table: no clue, it is a square table but that's it. If anything it looks like the things served on Pizza Hut pizzas
  • Well I spoiled the question for myself so... but I didn't have to choose, heck I couldn't choose even if I know what the questions are

Sure, OK.

Welcome to my brain

  • Red
  • Don't know, the "camera" wasn't panned up that high
  • All I really "saw" was jeans
  • Looked like one of those rubber balls that people like to bounce against walls, like in handball or squash. About as big across as the palm of your hand. Hollow, you could squish it without much effort.
  • one of those simple black square tables from Ikea

That's kind of what just popped into my head before I knew there were questions.

[–] [email protected] 7 points 1 day ago* (last edited 1 day ago) (2 children)

I find it very interesting that the vast majority of people saw a red ball. I did too.

::: spoiler

  1. red
  2. Indeterminate, mostly just an arm
  3. shoulder-length brown hair, androgenous body, hidden face
  4. Like a rubber bouncy ball you'd get in a party bag
  5. wooden, square

Mostly I already knew, but it felt like things were "filling in" as I tried to "remember" the image to answer the questions, especially around the person.

Honestly, it's patchy.

'ball on a table' is very generic, so my brain keeps suggesting different versions. A beach ball on my grandparents' living room table when I was a child. A fairly featureless basketball-sized sphere on a beech-like table in some kind of gallery-like environment. A tennis ball, but on little more than the concept of a table. The person, not being specified... could be anyone. In some versions it's my own arm, POV, in others it's like something seen out of the corner of your eye. Yeah someone came in and did a thing, I wasn't really looking.

The motion is more like a series of vignettes, unless I concentrate more - in which case the surrounding detail gets more abstract.

Now, if you give me details, that's another story.

A fuzzy yellow tennis ball on that cheap folding card table from my childhood with the padding cut off, leaving the textured fibreboard surface. My older sister strides up and shoves the ball across the table, making the flimsy legs wobble as she does so.

Do that, I can see the texture of the carpet and the bare walls from our shitty childhood apartment, I can downright smell the table and have the heft of the thing kinaesthetically along with the shape and visual textures. I can see the skitter and wobble of the ball across the table; my sister more an abstract bundle of mannerisms and gait, and the actual path of the ball is still more implied than observed, though.

For the most part, my visualisation is handwave, like looking through your blind spot or your peripheral vision: the part your brain makes up to fill in the missing details. When I read a book, it's like half-remembered cover-illustrations of the general scene: more vibe (sometimes richly textured, vivid vibe) than a literal image.

[–] [email protected] 1 points 22 hours ago* (last edited 22 hours ago)
  • Ball rolls about two feet and stops just before it rolls off the table.
  • White ball, polished surface, shiny
  • Male
  • Tall person, slender build, light brown hair, clean shaven, white button-up collared shirt, blue jeans.
  • Ball was a bit bigger than a billiard ball, but smaller than a baseball. Smooth, and heavy. Like a white cricket ball but with no seams.
  • It was one of those large common fold-up trestle tables but with a white table cloth on it.
  • I knew all those without having to think about it, or choose afterwards.

To me the imagery seemed like a cheesy "how to push a ball" educational video with a paid actor to demonstrate how to push the ball in the correct manner.

[–] [email protected] 7 points 1 day ago
  1. The ball was red.
  2. I have no idea.
  3. I have no idea.
  4. Like, maybe softball sized? A little bigger? I'm not sure.
  5. Square. It was made of brown.
