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'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)

  • rolls off the table, bounces a bit and rolls toward a glass door, where it also bounces gently after hitting the glass door. You could see outside into a yard that had a green garden in it. And trash bins outside.
  • blue
  • female, I think. But I didn’t pay much attention to the person at all.
  • long light brown hair, wearing a winter jacket, facing away from me. So I couldn’t see their face.
  • it was a dodgeball. Blue dodgeball. Not brand new. A few scuff marks on it. I could see like, the raised bumps on it.
  • it was a dark brown thin wooden table. It had a tray with a vase in the middle of it with a green plant with long grass-like leaves. There was a black, modern looking chandelier hanging from the ceiling above it. The table kind of looked like it came from IKEA lol.

The reason this is so detailed is that I just so happened to imagine the kitchen from a friend’s house. I already know everything that’s in there. It was easy to picture. And no, I didn’t come up with any of this as a result of answering the questions. I just saw it in my head.

[–] [email protected] 12 points 22 hours ago (13 children)

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] 4 points 18 hours ago

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

[–] [email protected] 1 points 15 hours ago

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] 3 points 21 hours ago (1 children)

Interesting point and I'm glad you made it, with a thought (?) experiment to check.

I think I am somewhat aphantastic, but not officially diagnosed.

Tap for spoiler

  1. Front forks down.
  2. No other damage.
  3. No other bikes, bike racks, or even street furniture. But as I read this question I retroactively added in the bike rack and street furniture outside my hometown's library.
[–] [email protected] 1 points 13 hours ago (1 children)

Interesting, I was also thinking of a nearby library when I came up with the scenario. It sounds to me like you don't have much aphantasia if you thought to have the forks down, most people I think just deleted the wheel and didn't think of how that might affect the bike. Either that, or you have a lot of experience seeing bikes with stolen wheels and you naturally picture it the way you normally see it.

I only knew the gender of the person and what kind of ball it was. I didn't imagine the other things at my first try.

[–] [email protected] 4 points 17 hours ago (1 children)

I imagined all the details for the items, but didn't pay attention to the person. I don't like looking at people's faces.

[–] AsudoxDev 1 points 17 hours ago

Same. Is there anyone that likes looking at people's faces?

[–] [email protected] 2 points 16 hours ago

My adhd ass missed the “someone” so it was a first person perspective. Lmao

[–] [email protected] 7 points 21 hours 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.

[–] [email protected] 1 points 12 hours ago

Labels should always be used with caution, but for me, learning about aphantasia led to me reconsidering the ways in which I imagine things, and this had a beneficial impact on how I communicated with people close to me. For example, I seem to be an odd mixture of relying on visual stimuli for thinking (so I have visual reminders all over, and reading complex info is way easier for me than hearing it), but also seem to lack the ability to visualise. This means that if my partner asks "hey, do you remember which drawer the mini screwdrivers are in?", I would usually be unable to answer, despite being able to walk in, take a glance at the drawers and go "that one, there". We didn't realise how frustrating this was for both of us until we reflected on the possibility of me having aphantasia. Whether I do or not doesn't matter. More relevant is the fact that now, when he asks me questions of where things are, it'll often be accompanied by a photograph of the location, which drastically improves my ability to recall and point to where the item is.

To some degree, I agree that it's nonsense to assign labels when in nature and in humans, variation is the norm. Certainly it can lead to reductionism and ignoring wide swathes of that variety if one is on a quest to sort people into boxes. However, there is still a lot that we don't know about how the brain works to process things and labels can be instructive either in researching aspects that we don't yet understand, or for regular people like me who find benefit in a word that helps me to understand and articulate that there are ways that my partner thinks and processes information that seem to be impossible for me to emulate. "Aphantasia" helped both of us to be more accepting of these differences.

Framing a phenomenon as either real or not isn't especially useful though, largely because of the ambiguity in the phrasing. An example in a different domain is that I've seen a wide variety of people claim that they don't think autism is a real thing. This tends to be received as offensive to many people, not least of all autistic people who feel like their lived experience is being directly attacked and questioned. Sometimes it is, and their anger is justified. However, I've also seen the "autism isn't a real thing" sentiment come from (often autistic) people critiquing the label and how it's used, especially in a clinical context. They argue that it perpetuates a binary framing of autistic and not autistic, which further marginalises people who do have a diagnosis, and isolates some people who have autistic traits but are overall sub-clinical in presentation (who may have benefitted from understanding these traits from an autistic perspective). Regardless of one's view of the arguments, it's pretty clear that these are two very different stances that might be described by "autism isn't a real thing".

I make this example because debating of the utility of labels can be a great and fruitful discussion that helps to improve our understanding of the underlying phenomena and people's experiences of them. Framing that debate as what's real or not can lead to less productive arguments that are liable to cause offence (especially on the internet, where we're primed to see things in a more adversarial manner)

It does, it's a studied and proven condition. No idea why you wouldn't believe it lol

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] 41 points 1 day ago (2 children)

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

[–] [email protected] 9 points 1 day 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.

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] 2 points 18 hours ago

Yep pretty much what I got

[–] [email protected] 8 points 22 hours ago (2 children)

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 20 hours ago* (last edited 19 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 19 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.

I have a question OP. Do you read fiction? Recently I've been wondering if aphantasia's why some people don't, almost seen unable, to read and enjoy.

[–] [email protected] 1 points 16 hours ago* (last edited 16 hours ago) (1 children)

This is a good point... I strongly prefer nonfiction over fiction, but it could just be Autism. I really only read fiction if it is really, really good... but I read them in the same way as I would read a nonfiction book as well, I'd be more interested in the themes of the book

  • rolled to the left and up a bit, fell off
  • Red
  • male
  • only saw the arm
  • tennis ball sized
  • folding card table
[–] [email protected] 1 points 15 hours ago

Very similar to mine. Although for me the ball was white and rolled right

I thought it was interesting I could only see the arm, probably because I wouldn't be able to picture the full body

[–] [email protected] 29 points 1 day 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] 11 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.

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] 1 points 15 hours ago

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.

[–] [email protected] 0 points 11 hours ago
  • black
  • male
  • nothing, it was just a hand pushing the ball
  • a ping pong ball
  • round, wood coloured, but thin like a metal coffee table.

I did have to think about how to put it into words, but the picture was fully formed before revealing the questions.

[–] [email protected] 1 points 16 hours 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] 1 points 16 hours ago
  • Striped white and blue
  • Male
  • Casual clothing, nondescript
  • About the size of a softball
  • Round wooden table

All of this came before I was asked about it.

[–] [email protected] 4 points 22 hours 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] 18 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?

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] 18 points 1 day ago* (last edited 1 day ago) (5 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 19 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.

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.
