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?

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.

HTH

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

Both my partner and I answered the same.

The ball was the size of a tennis ball, no colour.

The person had no gender or any distinguishing features.

The table was a standard kitchen table.

Neither of us knew what the test was about.

[–] [email protected] 5 points 4 hours ago (3 children)

Wait a second.

  • The ball had no color at all
  • The person who pushed the ball didn't even exist. It just got pushed by some invisible force. Naturally, they didn't have an appearance.
  • The ball was like... Small I guess?
  • The table had no properties at all.

Do people really usually have a more vivid picture in their heads? It's always just concepts with me. I'm confused.

[–] [email protected] 3 points 4 hours ago* (last edited 4 hours ago)

I also had the "I spent 23 minutes designing this scene in blender" impression of the ball, table, and disembodied hand. The table was made of light grey, the ball was made of light grey, and the hand was made of light grey

[–] [email protected] 2 points 4 hours ago

Yeah, same with me. But I knew the ball was pushed and rolled to the edge of the table and then fell, so I feel like I got the most relevant bit.

Tbh I've never been good at visualising faces, recognising people I know, retracing a route I've taken etc. This just feels like one of those things I've never really been great at.

[–] [email protected] 2 points 4 hours ago
  • What happens to the ball?

It slowly rolled toward the edge but stopped before falling to the ground. The path was somewhat eccentric because of the texture of the ball.

  • What color was the ball?

Yellow

  • What gender was the person that pushed the ball?

Male

  • What did they look like?

Green and white track suit (why? IDK), mid 60's Italian, chubby

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

It was one of those foam Nerf bullets, so about the size of a shooter marble

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

It was that black IKEA table where the four metal legs screw into the corners. About 6ft by 3ft.

  • 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 entire scene sprung into my head at once after reading that someone interacted with the ball

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

The ball was red. The gender of the person was unspecified, they were just a hand coming into the scene coming out of a long sleeve green shirt. And the ball was like the size of a softball. What I pictured was a zoomed in part of a table, Brown, but with two zoomed in of perspective for me to know the shape of the whole table.

[–] [email protected] 1 points 3 hours 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.

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

[–] [email protected] 1 points 4 hours ago* (last edited 4 hours 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] 1 points 4 hours ago* (last edited 4 hours 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.

[–] [email protected] 7 points 8 hours ago

Huh. The person was off-frame. And I'm pretty sure i retroactively chose a color for the ball.

I think I might have a black-and-white imagination.

[–] [email protected] 1 points 5 hours 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.

[–] [email protected] 3 points 7 hours ago

At first I saw something silhouetted on a card table. Then Action entered the story and I had to choose an adventure after being asked what happened.

I figured how it rolls might depend on who pushed it, and I already knew that. Kevin. Why he did it was less clear. Muscle memory placed us at a table in the canteen. Sitting across from him on any ordinary day, some rolled up piece of napkin or a wad of garbage paper might present itself as a projectile to reach him across the plates and glass between us.

Tonight we were in my kitchen, together there for the first time. I'd moved the table into the corner with both leaves open to make extra space for snacks for the party. We pushed the pretzels and empties aside and sat facing each other off the edge of the table, knees nearly interlocked.

My chin was on my hand and my heart was on the ceiling. We were laughing about something when I noticed the toy baseball on the table. The stairs creaked and the sound of background chatter crept in like a breeze that chilled my spine. He flicked the ball, and it rolled fast off the edge then fell to the floor with a flat thud.

The phone on the wall behind him rang, and I clicked to review the test questions.

[–] [email protected] 1 points 5 hours ago

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

[–] [email protected] 1 points 6 hours ago

red/blue stripes

none

they didn't

small pool ball

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

[–] [email protected] 1 points 7 hours 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.

[–] [email protected] 2 points 8 hours ago (1 children)
  1. Red
  2. An amorphous blob in a humanoid shape doesn't have a gender
  3. An amorphous blob in a humanoid shape
  4. Baseball sized
  5. Round, four legs, wood.

Haha no, I had to fill all that info in as I answered the questions. I mean, you can't literally see the things in your minds eye. They're more concepts.

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

The interesting part is that some people are able to see.

[–] [email protected] 2 points 9 hours ago (1 children)

I don't literally SEE it like I would with my eyes but:

Red ball

Clown, no idea of gender

Again, clown

Ball smaller than tennis ball, bigger than golf ball

The table I am sitting at and looking at right now.

And no, I can and do imagine how things look. It's a different sort of knowing/imagining than actual physical vision or dreaming though. Which led me to be confused about what exactly aphantasia is.

[–] [email protected] 1 points 8 hours ago

Yeah, same. I can envision things but I don't literally see it as though with my eyes. I can imagine an object and tell you how it would look if you rotated it, for example. I don't think I have aphantasia.

[–] [email protected] 1 points 7 hours 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

[–] [email protected] 2 points 9 hours ago
  • Small push, ball rolls a very short distance and stops
  • No color
  • Male, maybe an extension of myself doing the push
  • I did not visualize a complete person, only a suggestion of a body, and a arm/hand to push the ball
  • Size of two fists together
  • I did not visualize a full table, more like a camera view of a tabletop. Nondescript wood finish.

Did I already know? Sort of... My brain rotated through multiple possible imaginings. It worked forward, then reversed the logic to complete the scene. Nothing was set in stone: My brain decided that the ball would not roll off the table. Why? The ball has an uneven surface, it wobbled when stopping. Why? Because it has a surface like a soccer ball. Why? Because that was the first "look" my brain landed on that answered the question. I recall rotating through different colors and finishes, but after my brain imagined the ball stopping I had to come up with a why.

[–] [email protected] 1 points 8 hours ago

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

[–] [email protected] 7 points 14 hours ago* (last edited 14 hours ago)

Answer:

It was a simplistic grescale scenario devoid of unnecessary features. Think a simple and fast 3D render from the 90s or something. So everything was grescale, the person had no gender (or even features), and pushed a baseball sized sphere on a simple rectangular table made of indeterminate materials. Now I can picture something more detailed if required or desired but my mind focused on the mechanics of it all and kept details to a minimum. Asking for these details afterwards doesn't generate them retroactively.

[–] [email protected] 1 points 9 hours 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.

[–] [email protected] 3 points 12 hours ago
  • 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 12 hours 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] 1 points 9 hours ago* (last edited 9 hours ago)

It's a gentle push so the ball rolls for a second before falling off the edge of the table and bouncing away on the floor.

Ball Color: Bright red

Pusher Gender: Masculine

Pusher appearance: Caucasian, Tan suit, head was out of frame

Ball size: Tennis ball sized, but smooth with a seam around the middle

Table appearance: A square, short end table on a white studio backdrop. Dark wood with a glossy coating.

The important question: I can confidently say every question I already knew and was just describing what I was seeing, with the exception of maybe the pushers clothing. After reading the question my focus shifted to it and it visually resolved and I described it. Looked and felt almost the exact same way that you might not notice the details of an object in your peripheral because the focus of the scene was the ball, and then at a prompt, shifting your gaze and taking note of that object at the edge. It was framed like some kind of ball demonstration physics video.

[–] [email protected] 7 points 15 hours ago (1 children)

I have complete aphantasia, I can't even visualize a ball or table, or anything else - never have been able to, I see absolutely nothing when I close my eyes and can't visualize or see things in my head at all except when dresming. Same for my Dad. He can apparently visualize an extremely tiny amount (like the night sky but just black + stars, etc) when he's high on thc gummies. I've never been high so idk if it works for me.

It took me 24 years to realize that people actually can actually see images in their head when they think about something or intentionally imagine it. I always thought that phrases like "picture it in your head" or "see in your head what it will look like" were just phrases, not that people actually can see things when they think about it.

[–] [email protected] 2 points 15 hours ago (1 children)

Hmm have you been on LSD? I’m curious if your experience with it is different from someone who doesn’t have aphantasia?

I basically fill in the details as the questions were asked. It could have been anything from a billiard ball on a pool table to a rubber ball on a dining room table. Anything unimportant is basically left "unfilled" or generic until it needs detail.

The person who pushed it was vaguely male, again no details unless the question is asked. They may as well have been a featureless mannequin.

[–] [email protected] 6 points 15 hours ago

I do not have Aphantasia, but I've always been fascinated by other people's "normal". I always loved the "is my red the same as your red" thought experiment ever since I was a kid. I have spoken to people that claim to have Aphantasia, and they describe their experience as pretty normal. Instead of seeing an image in their head, they just.... know the thing. Where most people can visualize a scene in their head, Aphantasiacs apparently just feel and understand. It doesn't seem to impair them whatsoever and they seem to be perfectly normal people otherwise. My layman's explanation is maybe it's a vestigial function of the human brain back when we needed more empathetic or intuitive responses to stimuli, similar to the theory that ADHD would have been a benefit during hunter/gather societies.

[–] [email protected] 1 points 10 hours ago* (last edited 10 hours ago)
  • What color was the ball?
    Grey, I suppose? It wasn't important until this question so it was kind of colorless, even though I could picture it.

  • What gender was the person that pushed the ball?
    Androgynous.

  • What did they look like?
    Nondescript.

  • What size is the ball? Like a marble, or a baseball, or a basketball, or something else?
    A bit larger than a softball.

  • What about the table, what shape was it? What is it made of?
    It was a rectangular table. It shifted from being smooth and grey to a lightly finished maple, then back again.

  • Important question:
    I didn't really think about these details until asked.

[–] [email protected] 1 points 10 hours ago* (last edited 10 hours ago)

Color: red

Gender of pusher: undetermined

Looks of pusher: detached skinny white arm/hand

Size: roughly palm sized (full grown adult)

Table: wood, circular. Changed to black void with half pipe like pinball track upon being rolled.

After a quick visualization, that's what I got. Seeing the questions didn't change my answers

Edit: ball moved along the track for a moment before I stopped thinking about it, mostly since that train of thought made my brain switch to Sonic Spinball.

[–] [email protected] 4 points 15 hours ago

I was really surprised when I learned that the inner eye wasn't just some figure of speech, so I don't see anything, certainly no extra visual details.

Something is still happening though, I can sort of "feel out" shapes/volumes and motion, like depth perception with no visuals attached.

[–] [email protected] 1 points 11 hours ago

What do i have if i can't stop the ball from falling? Like the person stops it from one side and it bounces to the other and fall that way.

I also have trouble stopping clocks from spinning in my imagination

[–] [email protected] 5 points 18 hours ago

Background: I did this experiment with the pre-existing belief that I likely have aphantasia.

Starting with the important question, no, I didn't know the answer to these things before being asked

The ball was red, but I don't think my initial "rendering" involved a colour of a ball at all, because the colour isn't relevant to how it rolls. The ball felt cold, because that's one of the ways I understood its weightiness, and thus how it rolls. The ball was small enough to hold in one hand, but in "visualising" its size, I imagined how it would feel in my hand. The ball I imagined was a bit larger than a tennis ball and much heavier. I can imagine the force my fingers would need to exert to grasp it.

The person who pushed the ball had no gender because it wasn't relevant. When I considered the person's gender, they were a woman, but that information seems to have gotten lost when I "looked away" by considering other questions; when I reread the questions, I "forgot" what gender the ball pusher was, and this time they were man. I suspect that because the information wasn't relevant to the manner the ball was being pushed, the person pushing the ball was in a sort of superposition of gender, where they are both and/or neither man and/or woman, because it was liable to change whenever I "looked away".

The ball pusher(s) didn't look like anything unless I really pushed myself on this question and then I'm like "erm, I guess they were brunette?", but I think a similar thing happens as with the gender question — unless I have a way to remember what traits I assigned to the ball pusher, I'm just going to forget and have to regenerate the traits. I suspect that if I were actively visualising something, these details would stick together better, like paint to a canvas.

The table has a similar effect of nebulousness. My only assumption before you asked further about the table was that it was level (because the ball started at rest) and rectangular/square. When I tried to consider the table in more detail, I asked myself "what can a table be made out of". Wood comes to mind most obviously, because I have a wood table near me. Laminated particle-board is another thing. I also remember some weird, brightly coloured , super lightweight plastic tables from school. It could also be metal. It could have four legs, or it might have a central base like the dining table at my last house. It might be circular, or oval, or rhomboid. I think I just modelled it as squarish because I've learned enough mathsy-physics that I'm inclined to think of spherical cows, and having a straight edge is easier to model for mathematically, and to draw.

Brains sure are wacky, huh?

[–] [email protected] 7 points 20 hours ago

The ball rolls for a bit then stops

  1. Colorless ball
  2. Didn't image a gender, just the concept of a person
  3. They didn't look like anything
  4. I guess a perfect colorless sphere roughly the size of a tennis ball
  5. Pretty much just a rectangular flat surface. There's no color or material

I didn't know much about it except the size of the ball being roughly proportional to the size of a human hand
