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?

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?

[–] RecallMadness@lemmy.nz 1 points 19 minutes 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.

[–] django@discuss.tchncs.de 1 points 28 minutes ago

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?

[–] Narauko@lemmy.world 1 points 29 minutes 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.

[–] NorthWestWind@lemmy.world 1 points 31 minutes ago

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.

[–] merc@sh.itjust.works 1 points 32 minutes 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".

[–] RebekahWSD@lemmy.world 1 points 45 minutes ago

Don't know, they were an amorphous humanoid so I uh don't know for these two, baseball ish sized could fit in a palm, the platonic ideal of a wooden table. The first questions did not make me change the thing in my head. I don't think I see color in my mind eye, but I can uhhh label things with a color. Like. This ball is red, I think to myself, as the ball... continues to ball. Maybe if I imagined a specific red ball it world be redder.

[–] BuboScandiacus@mander.xyz 1 points 52 minutes ago* (last edited 51 minutes ago)
  • The ball was orange
  • I don't remember
  • I don't remember
  • As big as an orange
  • The ball was on a white surface
[–] Shelena@feddit.nl 1 points 1 hour 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.

[–] CheeseNoodle@lemmy.world 1 points 1 hour ago* (last edited 1 hour 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.

[–] sga@lemmy.world 3 points 2 hours 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

[–] Truffle@lemmy.ml 1 points 1 hour ago
  • Orange *No gender. *Bald mannequin, like the outlines of people in bathroom stalls. *Baseball *Square wooden table.
[–] UmeU@lemmy.world 1 points 1 hour ago* (last edited 1 hour ago)

Red

Didn’t think about gender

Didn’t think about what they looked like

Ball was baseball sized

It was a square wooden table

Bonus, I imagined the ball rolling across the table and then falling off the table and bouncing a few times on the floor.

I didn’t choose any answers after reading the questions, but didn’t have an answers for the person.

[–] mbtrhcs@feddit.org 1 points 1 hour 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.

[–] tiredofsametab@fedia.io 6 points 3 hours ago

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.

[–] Gaspar@lemmy.dbzer0.com 4 points 3 hours 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.

[–] AmidFuror@fedia.io 49 points 6 hours 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.

[–] TheBananaKing@lemmy.world 3 points 3 hours 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.

[–] Itisreallyboring@lemmy.world 1 points 2 hours ago* (last edited 2 hours ago)

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.

[–] ShittyBeatlesFCPres@lemmy.world 3 points 4 hours ago* (last edited 3 hours 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.

[–] keletappi@sopuli.xyz -3 points 1 hour ago* (last edited 33 minutes ago) (2 children)

Haven’t until recently thought much about people using vision-related words to describe thoughts. Never realized they mean those words literally. I suspect I have the aphantasia.

My answers to OPs questions:

  1. The ball has no concept of color, it’s an abstract notion of ball
  2. the individual is also an idea of a person that has ability to approach the table and the ball and apply force to it, but it is not fully thought out representation of a biological person, it has no such thing as gender or limbs, it’s a concept of “someone” as was required
  3. They (none of the objects or the person) don’t look like anything, they exist as ideas of entities in void
  4. The size is not set, so the ratios can be applied very fluidly to play out different sizes of objects or forces applied, like pushing force, or gravity, or lack of them. I thought this was very vague description so I thought best to make a few different tests to understand what would be outcome before continuing the question. When I got to the end (what happens..) I thought well a fuckton happens depending on multitude of other related but undefined things! What a stupid question.
  5. The table has no height, shape or edge, since none was required, but in a few cases there were tilts, edges, motion and other topologies, and whatnot. It’s not made of anything, it’s a concept.

You are all just hallucinating and not seeing the actual things going on, and that makes you all handicapped.

Edit: I guess I said something to upset some of you, please leave a comment to explain (maybe more detail than I’m “not special”)

[–] Cryophilia@lemmy.world 5 points 1 hour ago (1 children)

Unnecessarily aggressive lol

[–] keletappi@sopuli.xyz 1 points 57 minutes ago

I think you are correct, thanks for pointing it out to me. I don’t recognize that myself as well as I should.

[–] BuboScandiacus@mander.xyz 1 points 50 minutes ago (1 children)

Everybody can do think in concepts, you're not special in this regard

[–] partial_accumen@lemmy.world 2 points 3 hours ago

My answers:

  • What color was the ball? Metallic silver
  • What gender was the person that pushed the ball? A woman
  • What did they look like? Short straight black hair, pale skin tone, fit build, black blouse, plaid skirt, black leggings, wearing black pumps
  • What size is the ball? Like a marble, or a baseball, or a basketball, or something else? Slightly larger than a baseball, slightly smaller than a softball
  • What about the table, what shape was it? What is it made of? Wood, square, about 1 meter/yard square, thick square legs one at each corner.

Did you already know, or did you have to choose a color/gender/size, etc. after being asked these questions? All of this was a picture before seeing the questions. Other things about the image that weren't asked were also there like:

  • the room was lit from a single light bulb above the table with a wide shade. Light was cast straight down on the table/ball and extended slightly beyond the table, but I couldn't see how big the room was...until the ball rolled off the table and hit the floor. I could tell the floor was smooth wood and the walls in the room must also be of a hard material because the sound of the solid ball hitting the floor reverberated. The light showed one wall was red brick. It was indoors.
[–] clay_pidgin@sh.itjust.works 18 points 7 hours 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!

[–] ArbitraryValue@sh.itjust.works 8 points 6 hours ago (1 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.

[–] clay_pidgin@sh.itjust.works 3 points 5 hours ago

Hello, fellow odd brain!

[–] EpeeGnome@lemm.ee 2 points 4 hours 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.

[–] Today@lemmy.world 28 points 8 hours ago (2 children)

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

[–] IForgot@reddthat.com 1 points 43 minutes ago

Exactly. It rolls for a while unless it reaches an edge.

[–] gofsckyourself@lemmy.world 5 points 3 hours 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.

[–] Vanth@reddthat.com 0 points 2 hours ago

Visualise (picture, imagine, whatever you want to call it)

I ignored this portion of the instruction because it was unnecessary to answer the question of what might happen to the ball if it were pushed by someone. I didn't visualize anything until moving on to the spoiler questions. Even then, my brain mostly went "nah, we'd just be making up something to fill in details irrelevant to the question, don't waste the energy".

[–] Jordan117@lemmy.world 1 points 3 hours 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.

[–] bdonvr@thelemmy.club 2 points 4 hours ago* (last edited 4 hours 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.

[–] zaph@sh.itjust.works 1 points 4 hours 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.

[–] zlatiah@lemmy.world 3 points 5 hours ago* (last edited 5 hours ago) (3 children)

Oh my! I didn't know what to expect, and I have to say... I was quite surprised by some of your answers. Also confirmed to me that I am definitely not normal

Not many replies that are indicative of Aphantasia so... here goes nothing. I tried really hard at this okay

spoiler

I don't "see" see anything when I close my eyes. I can create a very vague concept of a ball, a table, and... kind of a person in my head, but I don't actually see the scene, I used to think when people say imagining things they were just making a metaphor. Things get really funk from here... But the overall schema feels more like one of those badly drawn scenes from the hit visual novel Slay the Princess. And yes I imagined it in 2D for some reason

  • Color: the ball doesn't have a color
  • Gender: it wasn't even a real person; it seems like a silhouette of the hand and back of a person
  • Looks: As I said, the person isn't even facing me
  • Size: No idea; in retrospect it's fairly large compared to the table (diameter probably 1/2-1/3 of table?), but the table is also an abstract concept so...
  • Table: no clue, it is a square table but that's it. If anything it looks like the things served on Pizza Hut pizzas
  • Well I spoiled the question for myself so... but I didn't have to choose, heck I couldn't choose even if I know what the questions are

[–] partial_accumen@lemmy.world 2 points 4 hours ago (1 children)

Just as an exploration with you on this. Use your same instructions for the placing and actions with one difference.

The room is pitch black, and you can't see a thing.

What do you hear?

Click for review questions:

  • what did the steps of the person sound like? Can you tell what kind of shoes they have with "heal/toe" impact sounds? single thumps indicating flat footfalls? nothing?
  • how long were they walking before they got to the table?
  • Did the ball make any sound as it rolled on the table? What kind of sounds? What kind of table would make that sound?
  • When the ball hit the floor did it bounce or fall flat? Was there an echo? Did the sound of the fall indicate you're in a tiny room or a giant room?
  • How close was the person to your point of observation?
  • Could you hear the person breathing?
  • What else did you hear that I didn't include here?
[–] merc@sh.itjust.works 1 points 21 minutes ago
  • The person didn't walk, that wasn't the focus of what I was imagining
  • The ball didn't make a sound when it rolled, but I was imagining a soft futsal ball that would make almost no noise rolling on a table. If I'd been imagining a marble or something that would have been different
  • The ball bounced once a bit, then fell flat, it's how a futsal ball bounces, it's a kind of "splat" sound with no echoes. I didn't imagine walls, so the room is effectively infinite sized
  • The person wasn't really part of what I was imagining. They were there to give the ball a push, but otherwise were irrelevant, so I didn't focus on them in any way

If I'd let my fantasy get "polluted" by the other questions and stories, I'd have answered differently. With all the questions about the person, I'd have invented a person and effectively "panned out" so that the person was part of what I was thinking about. Instead I went with my original visualization which just involved an effectively disembodied hand giving a ball a push. If this were a TV show or something, the only part of the person that I ever saw was the hand that gave the ball a push, everything else was "out of frame". But, I wasn't imagining a "frame", just whatever my mind's eye was focused on, which was almost entirely the ball, and not anything else.

[–] lunarul@lemmy.world 1 points 4 hours ago* (last edited 4 hours ago)

You imagined a lot more details than I did. For me it was just the concept of a ball. And then the idea of it moving. The person and the table were left our as irrelevant.

The thought experiment I use when explaining to people about aphantasia is a much simplified version of yours: "imagine a circle", "ok", "what color is it?"

That's it. People give an answer, sometimes including more details, like texture. Then I tell them that for me the question doesn't make sense, I just imagined the idea of a circle and didn't actually "see" anything, so there's no additional detail to it.

[–] Tippon@lemmy.dbzer0.com 1 points 4 hours ago

This sounds similar to how it works for me too. I closed my eyes to try this.

I saw a very rough version of the table that's in the room with me. The table is a low rectangular coffee table with a coarsely threaded grey throw over it going lengthways, but I saw it as a rectangular shape with a vague grey top. The ball was featureless with no colour, and was about the size of my fist, so an adult man's fist.

I saw a low quality arm push the ball, but I really struggled to picture it, and while I knew what would happen in real life, I couldn't picture it happening in my head.

It's strange, as sometimes I can picture things fairly well, but other times I can't do it at all. I have very vivid dreams on the occasions that I remember dreaming, but I can't close my eyes and picture my family. I know what they should look like, in the same way that I know what a rotating cow should look like, but I very rarely get any sort of mental image of them.

Ironically, I was in a coma a bit over a decade ago, and while I was in it, the dreams that I had were so realistic that it took me months to get things straight in my head.

[–] MicrowavedTea@infosec.pub 15 points 8 hours ago* (last edited 8 hours ago) (2 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?

[–] merc@sh.itjust.works 1 points 19 minutes ago

It's interesting how many people picked a brown wood table. I'd guess that's probably the most common material and colour for tables. But I'm typing this on a black table, and yet I still pictured a brown wood one.
