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?

The ball was silver and completely reflective. The seen basically looked like that image used for ray tracing testing. No gender just a hand. Table was black

[–] Tattorack@lemmy.world 1 points 1 month ago* (last edited 1 month ago)
  1. The ball I imagined was made of polished metal and reflected its environment.

  2. A man.

  3. I did not imagine a face. But he was wearing a dark blue business suit with a red striped tie. A watch was on the wrist of the hand that pushed the ball.

  4. About the size of a large orange.

  5. It was a smaller rectangular table made of a dark, varnished wood.

I'm an artist. I often tend to visualise what I want to draw quite well.

[–] mvirts@lemmy.world 1 points 1 month ago

The ball falls off the edge but doesn't make a sound, effectively disappears from the scene.

Glass ball for some reason

Nondescript woman, no distinct features, blurry at the edge of perception. Vaguely wearing business clothes.

Ball was softball size

Table was featureless but the size and color of the table I'm sitting at now

[–] HollowNaught@lemmy.world 1 points 1 month ago* (last edited 1 month ago)

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.

[–] Randelung@lemmy.world 1 points 1 month ago

red/blue stripes

none

they didn't

small pool ball

generic Simpsonesque brown, but it stopped existing towards the corners.

[–] Drivebyhaiku@lemmy.world 1 points 1 month ago

Huh. So I imagined the ball on the table immediately as a colorless glass sphere on a white table. Before I even read the prompt to push the ball in my imagination I had already placed my index finger on the ball and was rolling it around it place like a fidgit so I just tapped the ball to push it with my index finger so the person who pushed the ball was me (non-binary) for reasons that I was already interacting with the ball anyway. I imagined this in the first person so I didn't really see myself in full. The ball itself was baseball sized and rolled a short distance, stopped and wobbled after being pushed.

I didn't think about what the table was made of but the ball itself was glass that was smooth and cold to the touch. The table was square, waist height and dining room table sized. The room these objects were in was featureless and visualization was instant upon reading.

  • 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.

[–] Semjaza@lemmynsfw.com 1 points 1 month ago* (last edited 1 month ago)
  1. White/colourless ball. And honestly, more of a circle viewed from a perfect side on angle.
  2. I didn't visualise a person only the effect of their push on the ball. And like another poster corrected the slide to a roll.
  3. See above.
  4. Ball was of uncertain size. It was viewed side on, and no other objects to give a sense of scale. Maybe tennis ball sized, but I think that's retroactive.
  5. Table was rectangular and wooden. But no legs. Unsure of the thickness.

Included the timely-ness of the details in my answers above.

[–] merc@sh.itjust.works 1 points 1 month ago
  • The ball was a futsal ball, so white with green markings
  • I didn't see the person who pushed the ball, just their hand, I was concentrating on the ball
  • The table was at about the height of a typical dining room table, it was plain wood about 1cm thick with a dark top and had fairly thin black metal legs

I already knew the answers, for the most part. The questions didn't cause me to add more detail, but they did cause me to reflect on the details I had chosen. So, for example, I never looked at the person who pushed the ball. Because of that, I couldn't fill in any details about their looks or gender. But I did clearly see the hand giving the ball a push, and I think the hand belonged to someone white. Having said that, I did have to stop and think about the answer for the table. The table was part of what I imagined seeing, but it wasn't the focus of my attention. I realized I could think about what I had imagined and the details came to me. But, it's possible that I didn't actually dream them up until I was asked the question.

Also, nobody asked, but the ball fell down and hit a white surface (something like white tiles) and bounced the way a futsal ball bounces, which is to say mostly a soft "thud".

[–] Narauko@lemmy.world 1 points 1 month ago

The scene was like an example reel from a video game, greenscale-ish translucent humanoid mannequin standing in a pseudo void, with a nondescript rectangular table of a similar greenscale-ish semi translucent material, and only the ball is "finished" as it is the camera focus. It is approximately between baseball and softball size, smooth, but I did not pay attention to the color. There is an "interaction/activation" sound effect as the mannequin kinda leans over and lightly pushed the ball to cause it to roll. It rolls to a stop on the table top, and this action loops.

The center of focus pulled back as I read the questions, more becoming aware of them than choosing them, and the scene changed with a camera pull out as part of the "ball is pushed" tutorial clip.

I have realized how much growing up as a gamer as influenced my perspective.

My answers

  • It was sandy brown.
  • I didn't picture a person, but a real cat that I'm worried about. She's a female.
  • Like that specific furball looks like. She resembles savannah cats from a distance but she's a pure-bred mutt.
  • Around the size of my palm. Massive, springy.
  • I pictured the ball over the desk table that I'm using now.

I picked a lot of RL stuff (like the cat, or the table) to "build" the image with; I often do this. I picked all those things before seeing the questions.

[–] CheeseNoodle@lemmy.world 1 points 1 month ago* (last edited 1 month ago)
  • White

  • Not in shot, just a hand

  • The arm was the same complexion as my own

  • Tennis ball sized but made of that stuff billard balls are made of, smooth and shiny

  • Classic oblong wooden table, looks like that cheap ikea pine with a clear grain

  • The ball rolls along the table with again, the same sound you get with a billard or similar rigid ball rolling along a solid surface, upon falling off the table it hits the floor (pale orange ceramic tiles) and bounces a few times in that satisfying way that produces an ever increasing frequency until it stops.

  • I already knew and did not have to chose after being asked the questions.

[–] jared@mander.xyz 1 points 1 month ago

Tap for spoiler

  1. Red
  2. None
  3. Nothing
  4. Indeterminate
  5. Brown, indeterminate
  6. It's like looking at a watercolor through a frosted window.
[–] mbtrhcs@feddit.org 1 points 1 month ago
  • yellow
  • male
  • round face, beard, brown hair, mid 20s (I think probably some internet-famous person whose name I don't remember)
  • small plastic ball filled with air
  • a simple square table with a natural wood top and legs

That was my first thought. But then (before reading the questions) I also imagined other similar scenarios like with a soccer ball and my desk at work, lol.

My experience with this experiment was kind of like when they play memory flashbacks in movies, I could see the ball being pushed and falling, but with jump cuts and the timing was off. Detail-wise I'd say it was kinda like what you got from AI image generation when Dall-E first came out two-ish years ago.

I don't think I have the most visual imagination out there but if aphantasia is one end of the scale I'm pretty far to the other side.

[–] owsei@programming.dev 1 points 1 month ago

I imagined a red dodgeball on a small brown table. The person was just a thick stick figure and when the ball fell it bounced.

The color and shape I didn't actively choose, they cam be different, but I guess my brain has defaults.

The ball falling and bouncing, however, I had to actively think about, the same way I have to think about texture. I don't have to think about where the ball would stop, or how much it would bounce tho.

[–] viralJ@lemmy.world 1 points 1 month ago* (last edited 1 month ago)

So I cheated a little, because I'm at a table right now, so I didn't visualise the table just the ball on the table. It was about tennis size, but no texture, kind of light blue shading into lilac. The person pushing it was really just a hand.

So sounds like the only work I did was imagining the ball. I wouldn't say I knew in advance, and I wouldn't say I chose what it looked like. It just appeared and it was light blue.

Edit: the ball started rolling when pushed, but not long enough for me to know whether it fell off the table or not. But the rolling was just a concept. I can visualise things, but I can't visualise motion. Which I only discovered recently.

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

How can these guys have aphantasia?

Color: greenish-blue

Person: male (I identify as male, the person kind of represents me, I guess)

Looks: Cannot see entirely, because "the camera" is very near. Blue pants.

Size of ball: Fits in one hand. The ball is made of a light material and will probably bounce on the floor.

Table: Very generic table. Beige, light brown.

I think, all of that I knew before reading the questions, I was able to answer the questions without really thinking about it.

[–] Kingofthezyx@lemm.ee 1 points 1 month ago* (last edited 1 month 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. Probably the schizophrenia.

[–] Jordan117@lemmy.world 1 points 1 month ago

I pictured a smooth red rubber ball about the size of a baseball on my kitchen table. The "person" was more of an invisible force, not explicitly male but definitely not female. That might be male bias, or subtly thinking of myself doing it (combined with playing too many physics engine video games where your disembodied self pushes things around).

All of this was pretty vague though, like I didn't really imagine the details of the room or the exact path of the ball other than knowing it would roll off and bounce on the floor.

[–] zaph@sh.itjust.works 1 points 1 month ago

The ball is black, the table is black, the human is black. They're all just blobs I tell myself exist so I feel normal.

[–] Feathercrown@lemmy.world 1 points 1 month ago* (last edited 1 month 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).

[–] Adderbox76@lemmy.ca 1 points 1 month ago
  • gray ball, about the size of a typical dodge-ball.

  • Featureless, sexless "humanoid"; like a "suggestion of a person" or a "fuzzy shadow".

  • Round table. Nondescript. Most similar to one of those tall, small round tables you find in pubs. But again, featureless.

  • Nothing happens when the human pushes it. The human can't push it because the human has no physical form.

[–] lennivelkant@discuss.tchncs.de 1 points 1 month 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.

[–] BilboBargains@lemmy.world 1 points 1 month ago

The ball was black, made from rubber, tennis ball size. Only a hand was imagined. No particular colour or gender. The table was made from Elm.

[–] nyahlathotep@sh.itjust.works 1 points 1 month ago* (last edited 1 month ago)

spoiler

  1. red
  2. no gender
  3. just an outline, maybe a bit tall?
  4. it was around the size of a softball
  5. the table was circular and small for a table, like maybe two could sit at it. I didn't imagine a material.
  6. I imagined more about the ball than anything else, it was made of a spongy material like in those sponge brushes for painting, and it was red. The person was a complete blank slate. The table was only circular, nothing else.
[–] Valmond@lemmy.world 1 points 1 month ago

Small tennis sized ball whitish color on a whitish classic rectangular kitchen table. But the table is zoomed in quite much at the start so you only see the overside of it.

No specific gender, very neutral. Like a videogame character with few colors, white mostly. Now the scene is zoomed back to let you see the person walk up to the table.

Did not know. But when i read the others answers mine turned into a 1990 MTV music video where objects are immutable but displayed in lots of different ways, colors, textures, ... I also exploded it when the pwrson touched the ball for fun.

I have worked a lot in video games and scientific visualisation, so the test looks like something I'd make in a 3D engine I guess, least information possible to show the important things, the ball etc.

I can imagine and see about anything, colour, texture, forms, people, movements, but the more details the more zoomed in it gets. I can imagine you as lofi-girl looking at your phone, but expeession like "what the crap did I just read" imagining you reading this for example.
