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?

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.

[–] viralJ@lemmy.world 1 points 3 days ago* (last edited 2 days 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.

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.

[–] Fedizen@lemmy.world 1 points 3 days ago* (last edited 3 days ago)

Everything was shadows with rainbow outlines, basically.

I think this is a fun exercise, but Idk I'm oblivious to a lot of things excepts shapes and interactions. More telling is my dreams tend to fall into two categories:

Objects without details but with crisp, colorful outlines and dark scenes with illuminated spacces where the more fleshed out areas that are illuminated.

And my ability to imagine is similar- if no lighting condition is given my mental image is shadows with rainbow outlines. If the instructions include lighting the details are more robust: A cat will have a color, a ball will be plain and white and softball sized.

[–] sga@lemmy.world 4 points 4 days 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

[–] Drivebyhaiku@lemmy.world 1 points 3 days 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.

[–] blockheadjt@sh.itjust.works 2 points 3 days ago

Blue

Gender-nondescript, like a drawing in a school book

See above

Tennis ball size

Square, particle board like Ikea furniture

Some of them I extrapolated upon after seeing the questions because having unknowns in your mind's eye is not uncomfortable to people with intellectual integrity

[–] Classy@sh.itjust.works 2 points 3 days ago

What I don't like about this experiment is that being hyperphantic doesn't necessarily mean "you need photographic visualizations of every scenario at all times". My mind conjures scenarios differently depending on context.

I can imagine myself barely being able to see a ball on a table, let alone a person moving into view.

I can see the ball having a glossy, low-res texture alla 1980s CGI, with the ball being pushed by a polygon figure, moving without any real animation and limply falling off the table with no gravitational speed.

I can picture a worn, shiny leather baseball sitting on an old coffee table, stained walnut. The person is Mark Wahlberg and he has a smirk on his face as he lazily finger-flicks the ball, which only barely makes it to the edge of the table before just being able to tip off the edge, bouncing twice with a heavy bomp-bomp and rolling unevenly for a couple seconds. Mark winces because his finger hurts now. I could also imagine the flavor of the baseball and what it would smell like.

The point is that an aphantic might only be able to visualize this scenario at best as well as the first description, or perhaps not even at all and they can only 'know' of the movements in the scene with zero visual or otherwise relation to it.

Hyperphantics generally can conjure near limitless detail and they can retain that information visually for long periods of time without much effort.

[–] DancingBear@midwest.social 1 points 3 days ago

The blue ball won’t roll because it was on a table of clean laundry

[–] Gaspar@lemmy.dbzer0.com 4 points 4 days 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.

[–] TootSweet@lemmy.world 5 points 4 days ago* (last edited 4 days ago)

Neat!

spoiler

  • Red. It was rubber.
  • Male.
  • Tall, thin. I don't remember a face, but he was wearing an old-fashioned formal shirt and sport jacket. The cuff of the shirt was unbuttoned and folded back. He also wore a wide-brimmed black hat. (I'm currently watching an episode of Hell on Wheels which probably influenced that.)
  • Large for an apple, small for a canteloupe.
  • Square, dinner-table-hieight. Dark-stained wood. I'm no woodworker, so I wouldn't know what kind of wood it was, but I've got a couple of bookcases of the same wood and staining.

Aside from that, I can say it took place in an old cabin and in the background, I saw an open doorway to a... foyer? The door to the outside was open. It was very sunny. And I saw green grass outside.

And, I knew all those things before I got to the questions. I just had to consult/replay the scene in my head to get all the answers.

Seems fair to say I don't have aphantasia.

[–] TheBananaKing@lemmy.world 4 points 4 days 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.

[–] fruitycoder@sh.itjust.works 2 points 3 days ago* (last edited 3 days ago)

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

[–] Randelung@lemmy.world 1 points 3 days ago

red/blue stripes

none

they didn't

small pool ball

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

[–] Brkdncr@lemmy.world 5 points 4 days ago* (last edited 4 days ago)

I’ve never head of this test before now. Spoiler tags to help others avoid the answers before they take the test.

Tap for spoiler

The ball was somehow chrome but not reflective, and bigger than a large marble. The table was a flat plane with no features. The person pushing the table had no features. There were no other features within this thought space

[–] Okami_No_Rei@lemmy.world 2 points 3 days 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.

[–] Karcinogen@discuss.tchncs.de 2 points 3 days 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.

[–] I_Fart_Glitter@lemmy.world 1 points 3 days ago

Orange

Male

He was a server in a black waistcoat, white shirt. He was brushing the ball off the table before setting plates down.

It was a ball from a kid's ball pit, so a little bigger than a baseball, smaller than a softball.

The table was round, with a red gingham table cloth.

The orange ball on the red gingham table cloth were there immediately, once instructed to visualize a person pushing it, it only made sense that it was a server, since the table seemed restauranty.

[–] mvirts@lemmy.world 1 points 3 days 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

[–] beansbeansbeans@lemmy.world 2 points 3 days 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.

[–] pruwybn@discuss.tchncs.de 4 points 4 days 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.

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

[–] Cypher@lemmy.world 1 points 3 days ago

Light blue ball

Male

Medium height dressed in a long sleeved pale blue collared work shirt, wearing jeans, with a brown belt. Brown hair. Non-descript facial features.

Tennis ball sized

A white, rectangular wooden table.

I already knew, the picture formed instantly on reading the prompt. Initially my perspective was looking directly at the ball then when I read the part about pushing it off the table my perspective shifted further back.

[–] SomeGuy69@lemmy.world 2 points 3 days ago* (last edited 3 days 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.

[–] spankmonkey@lemmy.world 4 points 4 days ago* (last edited 4 days 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.

OK today I learned I may have aphantasia.

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

[–] deegeese@sopuli.xyz 4 points 4 days 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.
