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?

Red. Before

Dude. After

Me. After

Baseball. Before

White card table with grey liner. Before.

Ball rolled slightly forward after being judged by the person. Stayed in the table. Before

[-] SlapnutsGT@lemmy.world 3 points 14 hours ago

Before reading the questions I visualized an all white room, with an average square wooden table with a red ball about the size of the baseball on it and the person was a white man with black hair in a grey suit.

[-] Okami_No_Rei@lemmy.world 2 points 13 hours ago

The ball was a colorless wireframe. Color wasn't necessary for the scenario.

The person was genderless. Gender wasn't necessary for the scenario. They looked like a wire frame skeleton of a person.

The ball was roughly the size and density of the smallest size bowling ball.

Table surface was circular wireframe with four legs. Material wasn't filled in as I wasn't trying to model for friction.

My imagination doesn't tend to fill in unnecessary details. Too much wasted processing power. I also don't really envision things. Like, I don't "see" them in my head. I feel out the shapes and weights and other physical properties relevant to the scenario and let my intuitive understanding of physics roll the scenario forward.

Like, I know the ball rolled until it fell off the table, it fell some distance, then bounced off the floor three or four times with a sharp crack, as I filled in that the floor was concrete as soon as I needed to know how it would bounce, and the sound it would make filled in naturally from there.

I genuinely don't know whether how I think qualifies as aphantasia. I don't really imagine visual stimuli, but my imagination is very thorough for sound and feel.

  • Ball rolls a bit but stops before going off the edge of the table
  • Red
  • Male
  • Avg Height/Build, Brown hair, shaved face
  • Like twice the size of a marble, like a bouncy ball
  • Square, wooden table, lightly stained.

Knew the answers before being asked.

[-] shalafi@lemmy.world 5 points 16 hours ago

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.

[-] zlatiah@lemmy.world 4 points 16 hours ago* (last edited 16 hours ago)

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

I have known people with aphantasia who were avid readers of fiction, and I've read accounts that more or less say "good writing allows me to somewhat vicariously enjoy a sense that I don't have, perhaps similar to how deaf people can enjoy music.". Besides that, fiction is so diverse that the necessity of visualisation ability likely varies across genres, authors, time periods etc..

My gut says that aphantasia would almost certainly affect how people would engage with fiction, but that it's not a determinant of whether they do or not. Ditto for autism (indirectly responding to OP: I have anecdotally found that autistics are rarely ambivalent on fiction — we either can't get enough of it, or can't engage with it at all. Some people I have known have directly attributed their love of fiction to their autistic modes of being)

I can only see still frames of random motions and detective gadget animated is the character who flicks the ball. The red ball which I then added a hammer and sickle moves with illustrative wooshes across the table bounces off of a wall into detective gadgets eye.

[-] Dakkaface@lemmy.world 1 points 11 hours ago
  • Reflective metallic silver, like a ball bearing.
  • genderless
  • a mannequin silhouette
  • about the size of a large grape? Like a superball.
  • my wooden dining room table, background and all.

The focus seemed to be on picturing the table and ball, and the person pushing it was irrelevant other than to provide motive force, so I didn't spend any time to fill in their details.

[-] Bobmighty@lemmy.world 1 points 11 hours ago

My ball was blue. It's one of those dog toy soft bouncy ones. Table is rectangular, wood, with a light colored stain that's well polished. A man casually slaps the ball and I hear the sound that type of ball makes as it bounces without much force. It bounced once off the table, then off the wall onto the floor where it did the dribble bounce off the tile in the kitchen until coming to rest on the carpet in the living room. None of what I see is related to my house.

If I really wanted to, I can vanish into this world I've built for the ball. I can get lost, staring out a window or something while not actually seeing anything because I'm in my head. I have hyperphantasia. It's seen more often than aphantasia, but it's not exactly common. It's very useful for creative endeavors, but has a lot of pitfalls; usually involving spacing out at inopportune times.

[-] abbadon420@lemm.ee 1 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.

[-] stelelor@lemmy.ca 1 points 11 hours ago

Before reading the questions:

  • The ball was uniformly gray, with a slight shine.
  • The person was genderless and featureless. I only pictured their hand and arm pushing the ball. The moment of contact was indistinct, as if the arm was hiding the ball from view.
  • The ball was the size of a large watermelon.
  • The table was square, about 1m² , brown-gray, with four turned legs. Same material as the ball: uniformly colored and vaguely glossy.
[-] Grandwolf319@sh.itjust.works 3 points 15 hours ago

Amateurs, all respondents imagined something new.

My mind is so efficient, it just plays something back.

This is what I saw

Except he pushed it towards her instead of picking it up.

[-] thawed_caveman@lemmy.world 1 points 12 hours ago

Orange.

Dude.

Very stock photo, long dark green shirt untucked, but i had no details.

Like a big pomergranate, smaller than a football but bigger than an orange.

The table was made exclusively out of square shapes of the same dark brown, so for example no cylindrical feet. Kind of like a 3D model or the not-cheapest table at Ikea.

I had all of this before, but i didn't "see" it in the sense that people ususally mean because i have the most complete aphantasia that you can have. If you were to ask me how i saw it in my mind without litterally seeing it in my eyes, i'd have no answer. It's kinda like concepts.

[-] AmidFuror@fedia.io 92 points 1 day ago

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.

[-] greedytacothief@lemmy.world 7 points 18 hours ago

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)

[-] flamingo_pinyata@sopuli.xyz 4 points 15 hours ago

Mine got better as I got older. Especially after some experiments with psychedelics. I didn't think I was able to imagine a 3D object in detail, and for most of my life I wasn't. But then I had a shroom trip in which I was able to freely rotate an imagined 3D object. Even render an object in my mind based solely on touch.
Afterwards I went back almost to normal, but not completely. It's like I learned to use some previously inactive part of the brain.

[-] Karcinogen@discuss.tchncs.de 2 points 14 hours ago
  1. The ball was red
  2. It was a man
  3. They wore a t-shirt and jeans
  4. A small sized ball, like a stress ball
  5. It was a plain wooden table made out of cheap particle board or laminated wood.

I had to think of questions to these answers after they were asked. The only things that I already knew were it was a red stress ball and that it was a cheaply made wooden table. I imagined that the ball simply began rolling towards the edge of the table. The person was amorphous at best.

I don't think I have aphantasia, but I do think I have a weak imagination. When I try to conjure an object or place, it's always like I'm peering through a keyhole. Like an image with too much vignette. The objects are usually non-descript and are more like concepts than things.

[-] AsudoxDev@programming.dev 7 points 18 hours ago* (last edited 18 hours ago)

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.

[-] KittenBiscuits@lemm.ee 6 points 17 hours ago

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.

  • rolled to the left and up a bit, fell off
  • Red
  • male
  • only saw the arm
  • tennis ball sized
  • folding card table
[-] tuna@discuss.tchncs.de 2 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

[-] merc@sh.itjust.works 14 points 22 hours ago

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?

[-] SolarMonkey@slrpnk.net 12 points 19 hours ago

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.

[-] merc@sh.itjust.works 2 points 13 hours ago

If someone told you to study a ball for 20 seconds and then close your eyes, then asked you immediately after you closed your eyes what colour the ball was, could you answer? The second something disappears from your visual field, is it gone from your "mind's eye"?

What's interesting to me about this is that the way our visual field works involves a lot of fantasy. Like, our minds are convinced that we're currently seeing everything in front of us and most of it is in focus. But, in reality our eyes can only really see a tiny amount of the world in full focus at once, but they're constantly flickering around filling in details. This is why some optical illusions are so strange, because they show us that our visual systems are taking shortcuts and what we think we see isn't actually reality. It makes me wonder if people with aphantasia actually "see" the world differently too.

[-] Reyali@lemm.ee 1 points 11 hours ago

Not who you asked, but yes I could answer and also yes it’s gone from my mind’s eye. I would be answering from memory.

I have no mind’s eye. Full-stop. But I have memory and can recall details without needing to see the thing.

If you can remember someone’s name after meeting them, that’s the same process it would be for me to remember their hair or shirt color.

So as someone who coaches sometimes I have to ask. Can you imagine and feel body movements? Sometimes I'll ask someone to visualize themselves performing an action before they do it.

[-] SolarMonkey@slrpnk.net 1 points 11 hours ago

Not really, but typically if I can see someone else do a motion I can self-insert the movements I’d need to make to duplicate it, so that might just be a disused function for me.

Although that’s a good question, because I do have special memory that I use for a lot of things, and it involves movement, but maybe not in the same way someone else would (eg I can count the windows in my place by simulating a walk through my house and “opening windows” like I do on nice mornings, but I often forget about out-of-the-way non-opening windows because they aren’t part of my muscle memory)

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

[-] dgmib@lemmy.world 2 points 15 hours ago

My mental image of the bicycle changed as each detail was added, but sometimes the detail changed the image (the handlebars were straight until you said they were dropped) and sometimes the detail didn’t exist; the dropped handlebars were wrapped in handlebar tape, but that tape didn’t have a colour (not sure how to explain that better) until you mentioned it was black. Most of the details “added” something to the scene rather than “changing” an assumed detail.

The “front forks on the ground” question was particularly interesting to me.

The bicycle started with two wheels, and front wheel just sorta disappeared from my image when you mentioned it was stolen, but the front fork remained floating in the air as if there was a wheel still supporting it. But asking the question about the forks on the ground made gravity exist, and then there had to be a reason it was floating, which became it was being held up by the U-Lock.

I seem to imagine scenes with few superfluous details that mostly includes only what is mentioned or implied by the narrative. But it’s super interesting to me what details we’re in fact implied.

The ball on the table was similar. The table was at waist height to the person, and the ball had a specific size of roughly the size of a racket ball because it had to be something that could be easily pushed. But the person pushing it was just a silhouette of a person, it had no gender, the only thing I pictured clearly was the hand that pushed the ball. It was pushed in an intentional way that made the ball roll across the table away from the “person” (as opposed to bouncing, or pushed sideways)

The table was just an elevated plane it had no texture, or even legs supporting it, (probably because there was no ground for those legs to be on,) it didn’t go on forever, you could see the end of the table, but it also didn’t have a size.

  • 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.

[-] lenz@lemmy.ml 3 points 16 hours ago* (last edited 16 hours ago)
  • 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.

[-] beansbeansbeans@lemmy.world 2 points 14 hours ago

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.

[-] lennivelkant@discuss.tchncs.de 1 points 13 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.

[-] Today@lemmy.world 52 points 1 day ago

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