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 visualized a blue ball the size of a tennis ball being pushed forward on a flat white surface by a shadowy figure with only the hand being visually clear. Upon the follow-up question, I believe that it solidified the gender in my mind to be male and also prompted me to think about the surface of the table edges in relation to where the figure stood. However, my main focus was on the blue ball and the hand pushing it forward over a white surface.

No matter how much I tried to focus, all I can see is Mickey Mouse in a magician's cap trying to control buckets and mops.

I might have hyperfantasia.

A vague thought of a ball and knowledge of what would happen. Nothing else.

[–] [email protected] 16 points 6 days ago

Exactly. There's no need to add more details unless that's part of the requirements. Otherwise it makes it harder to keep track of things. Keep it simple first, then add complexity as needed.

As an aphantasia person myself, it is honestly mind boggling that people can visualise things that aren't there. Like that must be so much effort on things that aren't needed.

Suppose it means you can just have a wank and not need porn though.

[–] [email protected] 37 points 6 days ago (1 children)

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 6 days 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.

I've put some effort into improving my visualization since learning about aphantasia. Upon reading the prompt, I was able to imagine a colorless ball, but with shading to indicate a 3D shape, like a preview render in a CAD program. That's progress! It didn't have a size inherently. For the table, I could picture a white, rectangular plane hovering in a black void. If it was a normal dinner table size, then the ball was something like a softball or basketball.

And that's it. That exhausted my ability to visualize. No person, no push, no motion. Best I can do is to see the white rectangle after the ball has rolled off of the edge.

[–] [email protected] 6 points 4 days ago (1 children)

The ball was red, like a red rubber ball. The person was sort of indistinct from the neck up, it was more like my view was focused on the ball itself and didn't see a face, but it was a man, wearing a white shirt and dark tie, and dark pants. The ball was about the size of a baseball, wasn't completely smooth and shiny, sort of a matte with a slight grippy texture. Table was square, wood, like a medium brown color. The ball rolled off the table and bounced a few times.

All these decisions were automatic when reading the prompt, it's what I saw.

I've just become aware of aphantasia myself, I have a few family members who have it apparently. I was talking to my BIL about it the other day, I was saying how I'm a big fan of reading, but I mostly read nonfiction. He said he doesn't read much, mostly biographies, but fiction doesn't do much for him because he can't picture anything in his head. I can picture everything in great detail when I read fiction. Its interesting because our minds work very differently

[–] [email protected] 3 points 4 days ago (1 children)

I imagined the same red, baseball-ish sized rubber ball. Not sure why that's my default for "ball."

[–] [email protected] 2 points 4 days ago

+1 for a red rubberlike ball ... looks like a pattern emerges

[–] [email protected] 23 points 6 days ago* (last edited 6 days 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?

Wait a second.

  • The ball had no color at all
  • The person who pushed the ball didn't even exist. It just got pushed by some invisible force. Naturally, they didn't have an appearance.
  • The ball was like... Small I guess?
  • The table had no properties at all.

Do people really usually have a more vivid picture in their heads? It's always just concepts with me. I'm confused.

[–] [email protected] 5 points 5 days ago* (last edited 5 days ago)

I also had the "I spent 23 minutes designing this scene in blender" impression of the ball, table, and disembodied hand. The table was made of light grey, the ball was made of light grey, and the hand was made of light grey

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.

So, in this experiment you're asking people to picture a certain situation that doesn't call for any specific details, then asking them to describe the unnecessary details they came up with: colour of the ball, etc.

I'm curious if the people who have aphantasia can picture something in their heads when it does call for all that detail.

Picture a red, 10-speed bike with drop handlebars wrapped with black handlebar tape. It's locked to a bike rack on the street outside the library with a U-lock. You come out of the library and see that the front wheel has been stolen. Think about how that would look. Picture the position of the bike, and anything you might look for if it were your bike and you were worried. Pretend you needed to examine the situation in as much detail as possible so you could file a police report.

Questions

  1. Were your front forks resting on the ground, or up in the air?
  2. Was there any other damage done to your bike or to the lock?
  3. Are there any other bikes nearby? People nearby? Security cameras that might have caught the crime?

[–] [email protected] 12 points 6 days ago (15 children)

I’m aphantasic. You can say “picture this” followed by whatever you like. It’s not possible for me in any way. Growing up I honestly thought “picture this” or “close your eyes and see” was just metaphor. I legitimately didn’t understand other people can see things.

My mind has a verbal descriptive stream, and I’m good with muscle-based or proprioceptive spacial memory, and the two combine to handle most things, but nothing visual. So like I can easily describe things from memory or from an idea, and it’ll be fully consistent, but not something I see.

If you have aphantasia, and not just hypophantasia, it makes no difference how much detail is provided, there’s a total, fundamental, inability to visualize things.

I have aphantasia, and people really struggle to comprehend what it means or what it's like. Now to be fair, I don't really comprehend how people without aphantasia think or process things either.

  1. Were your front forks resting on the ground, or up in the air?

No idea, all I could think was that the front tire was missing, it didn't occur to me to think how that affected the bikes position.

  1. Was there any other damage done to your bike or to the lock?

I didn't think about there being any damage.

  1. Are there any other bikes nearby? People nearby? Security cameras that might have caught the crime?

I had just thought of a bike rack with only my bike, no people or other bikes nearby. Looking for security cameras seems obvious now that you mention it, but I didn't think of that. If you had said "what advice would you give if your friend walked out and found their bike had been stolen/vandalized" I probably would have thought of that, but trying to think of an abstract situation is much more difficult for me.

[–] [email protected] 6 points 6 days ago

This was fun to read. Everytime I read a new detail the scene in my head changed :)

Huh. The person was off-frame. And I'm pretty sure i retroactively chose a color for the ball.

I think I might have a black-and-white imagination.

[–] [email protected] 8 points 5 days ago (2 children)

I have complete aphantasia, I can't even visualize a ball or table, or anything else - never have been able to, I see absolutely nothing when I close my eyes and can't visualize or see things in my head at all except when dresming. Same for my Dad. He can apparently visualize an extremely tiny amount (like the night sky but just black + stars, etc) when he's high on thc gummies. I've never been high so idk if it works for me.

It took me 24 years to realize that people actually can actually see images in their head when they think about something or intentionally imagine it. I always thought that phrases like "picture it in your head" or "see in your head what it will look like" were just phrases, not that people actually can see things when they think about it.

Both my partner and I answered the same.

The ball was the size of a tennis ball, no colour.

The person had no gender or any distinguishing features.

The table was a standard kitchen table.

Neither of us knew what the test was about.

[–] [email protected] 7 points 5 days ago* (last edited 5 days ago)

Answer:

It was a simplistic grescale scenario devoid of unnecessary features. Think a simple and fast 3D render from the 90s or something. So everything was grescale, the person had no gender (or even features), and pushed a baseball sized sphere on a simple rectangular table made of indeterminate materials. Now I can picture something more detailed if required or desired but my mind focused on the mechanics of it all and kept details to a minimum. Asking for these details afterwards doesn't generate them retroactively.

[–] [email protected] 3 points 4 days ago (1 children)

What does it mean if I already knew the answer to every question except what the person looked like?

[–] [email protected] 2 points 4 days ago

Same here. I knew it was a man but nothing else. But I had a clear view of a small red rubber ball on a card table.

[–] [email protected] 8 points 5 days ago

The ball rolls for a bit then stops

  1. Colorless ball
  2. Didn't image a gender, just the concept of a person
  3. They didn't look like anything
  4. I guess a perfect colorless sphere roughly the size of a tennis ball
  5. Pretty much just a rectangular flat surface. There's no color or material

I didn't know much about it except the size of the ball being roughly proportional to the size of a human hand

[–] [email protected] 10 points 6 days ago (3 children)

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?

The ball had no color, the person had no gender or specific form other than vague shapes (the hand and arm being the most visualized), no memory of deciding any specific clothing, the ball was the most fleshed out part where it was the size of a softball. The table was square with vaguely wood coloring. The size was about 2 ft by 2ft maybe 3 ft high.

I did not already know most and I did not retroactively change them. I gave answers as I remembered my visualization.

[–] [email protected] 6 points 5 days ago* (last edited 5 days ago)

I basically fill in the details as the questions were asked. It could have been anything from a billiard ball on a pool table to a rubber ball on a dining room table. Anything unimportant is basically left "unfilled" or generic until it needs detail.

The person who pushed it was vaguely male, again no details unless the question is asked. They may as well have been a featureless mannequin.

[–] [email protected] 2 points 4 days ago
  • small dull red rubber ball
  • no obvious gender
  • they looked simple, like a Simpsons character. Impression of having a body, but only actually saw their hand
  • table was standard rectangular, wooden affair

My visualisation is quite chaotic, so I mostly see a jumble of overlapping objects then have to choose which one to focus on.

Surprisingly, I had a real hard time visualising the ball rolling on its own. The hand was either pushing it or it was bouncing off of the floor.

Interesting exercise!

[–] [email protected] 7 points 6 days ago (1 children)

I've noticed that after getting older, suffering several concussions, a short spat with drinking, and COVID that my ability to picture things in my mind has degraded a lot since childhood.

Does your ability to imagine things naturally decline? I remember as a lad I could vividly imagine the feeling of things. My imagination was also much more colorful. But I could never see things in 3D like some people can (I've worked with some really talented tradesmen/machinists who can like assemble or fold or machine a piece in their mind, I don't know maybe that's just practice)

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.

Grey, female, cartoonish with that weird bob round kind of look that comes with bushy brown hair that's slightly longer than shoulder length, slightly larger than a ping pong ball, wooden square/rectangle, no.

[–] [email protected] 3 points 5 days ago* (last edited 5 days ago)

Color - none (I hate not being able to visualise color as I hate doing 3d texturing work in blender and I would like to be able to enjoy it)
Gender - ambigious
Look - lack of info
Ball - unpleasant to touch, got pushed from the top, palm sized, it made a sound, the scene looped before the ball fell off the table, in the next iterations the ball was made of foam, and lacked sound, the camera spunn around the table.
Table - four legs, square, standard height.

[–] [email protected] 5 points 5 days ago

Background: I did this experiment with the pre-existing belief that I likely have aphantasia.

Starting with the important question, no, I didn't know the answer to these things before being asked

The ball was red, but I don't think my initial "rendering" involved a colour of a ball at all, because the colour isn't relevant to how it rolls. The ball felt cold, because that's one of the ways I understood its weightiness, and thus how it rolls. The ball was small enough to hold in one hand, but in "visualising" its size, I imagined how it would feel in my hand. The ball I imagined was a bit larger than a tennis ball and much heavier. I can imagine the force my fingers would need to exert to grasp it.

The person who pushed the ball had no gender because it wasn't relevant. When I considered the person's gender, they were a woman, but that information seems to have gotten lost when I "looked away" by considering other questions; when I reread the questions, I "forgot" what gender the ball pusher was, and this time they were man. I suspect that because the information wasn't relevant to the manner the ball was being pushed, the person pushing the ball was in a sort of superposition of gender, where they are both and/or neither man and/or woman, because it was liable to change whenever I "looked away".

The ball pusher(s) didn't look like anything unless I really pushed myself on this question and then I'm like "erm, I guess they were brunette?", but I think a similar thing happens as with the gender question — unless I have a way to remember what traits I assigned to the ball pusher, I'm just going to forget and have to regenerate the traits. I suspect that if I were actively visualising something, these details would stick together better, like paint to a canvas.

The table has a similar effect of nebulousness. My only assumption before you asked further about the table was that it was level (because the ball started at rest) and rectangular/square. When I tried to consider the table in more detail, I asked myself "what can a table be made out of". Wood comes to mind most obviously, because I have a wood table near me. Laminated particle-board is another thing. I also remember some weird, brightly coloured , super lightweight plastic tables from school. It could also be metal. It could have four legs, or it might have a central base like the dining table at my last house. It might be circular, or oval, or rhomboid. I think I just modelled it as squarish because I've learned enough mathsy-physics that I'm inclined to think of spherical cows, and having a straight edge is easier to model for mathematically, and to draw.

Brains sure are wacky, huh?

[–] [email protected] 3 points 5 days ago* (last edited 5 days ago)

A colorless ball is pushed by a non existent person and rolls slightly at a linear speed and then ceases to exist. The ball had no size and I don't remember the table existing.

[–] [email protected] 6 points 6 days ago (3 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.

[–] [email protected] 19 points 6 days ago (1 children)

I have aphantasia. The reason this experiment works is because someone with aphantasia will logically think about what they're being asked, but since they're not really "picturing" it, they won't have any answers about details. Color, type, and size of the ball? I have no idea, that information wasn't relevant to my mental checklist. For me, it really does work like a checklist. My brain supplies exactly zero imagery. For some people it's more like a spectrum, where they might be able to have a hazy picture with minimal details.

But aphantasia is 100% real. It's just hard for people to believe it because it's so foreign to the way they're used to thinking, in the same way it sounds unbelievably exhausting to me that regular people are constantly creating movies in their heads.

[–] [email protected] 8 points 5 days ago (2 children)

I think my brain might just be lazy... I skipped over the entire walk to the table part. And just imagined a detached arm pushing the ball on a surface, until it rolled off the surface and that was all.
