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?

OK today I learned I may have aphantasia.

It suffices to say, the follow up questions were bizarre to me.

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

I fantasized all the details as they were asked in the prompt, but didn’t give an identity to the ball-pusher until the quiz asked for it.

[–] [email protected] 4 points 1 month ago* (last edited 1 month ago)

It was a billiards/pool ball, but no idea which one as I just associate balls on tables with playing pool.

No idea on gender, formless concept.

No idea on looks, just a concept.

Whatever size a pool ball is, 2-3 inches? Just a concept though.

It is a pool table with green felt and a raised edge and six pockets because that is what a pool table is. Can't really see it. Just aware of it's general properties and how the felt and wood feels.

Eveey detail is based ona pool tabke and ball because my first thought about balls on tables is playing pool. Without the table detail I wouldn't have anything at all to work with.

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

Very interesting!

My resultsThe ball was about the size of a baseball, and the table was square, but I couldn't answer any of the other questions without just making something up when they were asked.

  • rolled to the left and up a bit, fell off
  • Red
  • male
  • only saw the arm
  • tennis ball sized
  • folding card table
[–] [email protected] 2 points 1 month 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] 4 points 1 month 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 month 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] 4 points 1 month ago

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] 4 points 1 month 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] 4 points 1 month ago

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] 3 points 1 month ago

That is interesting. I imagined it more like an abstract physics problem than an actual scene. My ball was about 6 inches diameter, made of a nonspecific hard but not very dense material similar to, but not necessarily solid plastic, of no specific color. It was in the center of a table roughly 3 x 6 feet in surface at normal sitting table height, and was also of no specific color or material. The person was just the vague notion of a person applying a push slightly off from across the short axis of the table. The ball bounced slightly on the generic idea of a floor as it rolled away. My mind quickly supplied the additional details when requested, but not until then. (Yellow ball, wood table, etc). If I'd been asked in a way that didn't feel like a physics problem, but instead asked me to imagine a scene, I would already have had many of those details in my mental view.

[–] [email protected] 3 points 1 month ago

spoiler-titleAm I the only one who imagined things that they interact with frecuently?

  1. The ball is green and its the one I got for my cat.
  2. Female, she gently pushed it with one finger
  3. It was my mom (idk why)
  4. About the size of a lemon.
  5. I just Imagined my table. Medium sized, thick with fake wood vinyl or something. I even imagined the mess that is on it.

I alredy knew, as I said, I imagined things I already know. And the ball bounced like 4 times before rolling out of the door.

What does it mean? lol

Edit: Added the spoiler thing. Quite interesting to read others replies.

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

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

  • What color was the ball?

I didn't see a color in my visualization, but I know it was red.

  • What gender was the person that pushed the ball?

They were genderless; more of a concept of a person than an image of one.

  • What did they look like?

Like...an area of visual space that my mind attached the identifier "Person" to.

  • What size is the ball? Like a marble, or a baseball, or a basketball, or something else?

A little smaller than a tennis ball, but bigger than a ping pong ball.

  • What about the table, what shape was it? What is it made of?

I didn't see either property in my visualization, but it's wooden and round.

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?

Lol. Well, I guess I botched that one. Obviously I did not know before being asked these questions, for most of the answers.

[–] [email protected] 3 points 1 month ago* (last edited 1 month ago)

SpoilerColorless. Genderless. The forbidden lovechild of Bongo Bongo and Turnip Head. Ping Pong sized. Rounded wooden table.

Visualizing takes work so generally only what's needed is there. But sometimes the darker thoughts escape out from the dungeon.

[–] [email protected] 3 points 1 month ago

I didn't know most answers, my mind kinda works with the concepts. The ball was there, but there was no color, not even a grayscale, but the absence of color ( I have difficulty imagining colors in general), the pweson was there, and was a woman, but with no face of features. I don't even know if i really pictured a woman, or if my mind worked on that after seeing the questions. The table was there, but was simply a plane for the ball to be on, without features.

Now that I write this, it seems weird. Do people picture scenarios like this as if seeing a real scene? Can this be related to aphantasia? Should I be worried?

[–] [email protected] 3 points 1 month ago* (last edited 1 month 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] 3 points 1 month 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.

[–] [email protected] 3 points 1 month ago* (last edited 1 month 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.

[–] Grandwolf319 3 points 1 month 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.

[–] [email protected] 3 points 1 month ago* (last edited 1 month ago)

In my head, a red rubber ball the size of a baseball rolls off a square wooden table and falls on the floor. A guy pushed it.

Edit: I knew ahead of time. I added more detail once I saw the quiz but I can imagine pretty vivid images.

[–] [email protected] 3 points 1 month ago* (last edited 1 month ago)
  • 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.

[–] [email protected] 3 points 1 month ago* (last edited 1 month 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] 2 points 1 month ago* (last edited 1 month ago)

Purple-ish

Male? Maybe?

Too abstract I more imagined an arm more than a whole person

Baseballish

Square, I dunno it was also purple. I get very like, early computer animation type vibes from the whole scene. "Ball" and "table" without any context just leaves everything kinda blank.

I think I already knew. Maybe the gender one was a stretch.

[–] [email protected] 2 points 1 month ago* (last edited 1 month ago)

The ball was white/light gray. It has the surface texture of plaster of Paris, but it is somewhat lighter than would be appropriate for its canteloupe-like size.

I don't think I actually pictured a whole person as pushing the ball, more likely it was a disembodied hand or the general sensation of pushing it myself.

I remember being specifically intrigued that I pictured the ball rolling back towards the center of the table and pondering why I had chosen the table to be slightly concave. I don't remember more attributes of the table, but I have the feeling that has more to do with inattention to its details rather than not picturing them at the time.

I imagine that, based on the framing of the story, my interpretation was to picture the sphere as a literal entity, but the person as the "concept of a push"... The table probably lied somewhere in the middle.

[–] [email protected] 2 points 1 month ago* (last edited 1 month ago)

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] 2 points 1 month ago (2 children)

I don't have aphantasia, but a rather vivid imagination sometimes. Also, a lot of my answers were indirectly influenced by my immediate surroundings:

  • What color was the ball? - Red
  • What gender was the person that pushed the ball? - Male
  • What did they look like? - I only imagined seeing the person up to the waist, approaching the table and giving a push to the ball. I pictured him with social attire.
  • What size is the ball? - Tennis ball, but very smooth. It was smack dab in the middle of the table, too.
  • What about the table, what shape was it? What is it made of? - Round glass.

A question for those of you who have, or suspect you have aphantasia, how are your dreams like? Can you imagine and "hear" sounds?

[–] zaph 3 points 1 month ago

how are your dreams like

Pretty sure I dream normally. Can't discern faces but I know I can see things.

Can you imagine and "hear" sounds?

Basically how I function. If I'm thinking of a song I know decently well or heard recently it's like a live show I can control. Just with the lights off.

  • The ball was red and smooth and uniform and shaded like it had been painted there or drawn with colored pencil.
  • the gender of the person was indeterminate, perhaps leaning female
  • they did not have a definite look to describe, it was more a concept of a person. They were a featureless, fuzzy, void-white silhouette adorned only by a similarly featureless light blue t-shirt, black pants and black hair, all so ill-defined it was as if they they had been hastily cut from craft paper and slapped over top the glowing form. Like the color scheme of the fitness boxing mascot, but the more simplified form of South Park Canadians, and more amorphous.
  • the ball was slightly larger than a baseball but smaller than a softball
  • the table was rectangular, of beige ‘wood’ with a light grain, and very sharp edges. It looked distinctly like it was out of a low poly video game.

Important question: The ball and table were distinct and known but oddly not “real-life”. The person was very indistinct and the gender is merely speculation. The edges defining their arms and hands became more defined as they approached and interacted with the ball. The color and form of the clothing and hair manifested then too.

Interestingly, I “know” the visualization took place in my kitchen, in an orientation different than my actual kitchen table. I saw the light from the windows Illuminate the table and the ball, and I could tell where I was in the space watching it happen, but the kitchen wasn’t there and neither was I. The table, ball and person appeared alone in a murky dark void.
