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?

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 2 months 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] 2 points 2 months 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 2 months 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] 2 points 2 months 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] 2 points 2 months ago* (last edited 2 months 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.

  • 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 2 months ago* (last edited 2 months 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.

  • 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 2 months 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] 7 points 2 months ago* (last edited 2 months 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 2 months ago

I instantly saw a soccer ball on our dining room table. The push throws a glass of the table.

  • The color of the ball was white with black pattern like a classic soccer ball.

  • The gender was male.

  • I didn't see the person clearly, only the hands pushing.

  • Soccer ball

  • The table in my imagination was exactly our light brown beech wood dining room table.

The points described were instantly in my head. Only for the person itself I would need to try again.

[–] [email protected] 6 points 2 months ago* (last edited 2 months ago)

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] 8 points 2 months 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 2 months 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?

[–] [email protected] 1 points 2 months ago

Nope, haven't done anything harder than ibuprofen tbh, never had a desire to try. I do dream visually though

[–] [email protected] 2 points 2 months 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

[–] [email protected] 5 points 2 months 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 2 months ago

I can only see still frames of random motions and detective gadget animated is the character who flicks the ball. The red ball which I then added a hammer and sickle moves with illustrative wooshes across the table bounces off of a wall into detective gadgets eye.

[–] [email protected] 1 points 2 months ago
  • Reflective metallic silver, like a ball bearing.
  • genderless
  • a mannequin silhouette
  • about the size of a large grape? Like a superball.
  • my wooden dining room table, background and all.

The focus seemed to be on picturing the table and ball, and the person pushing it was irrelevant other than to provide motive force, so I didn't spend any time to fill in their details.

[–] [email protected] 2 points 2 months 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.

[–] [email protected] 1 points 2 months ago

My ball was blue. It's one of those dog toy soft bouncy ones. Table is rectangular, wood, with a light colored stain that's well polished. A man casually slaps the ball and I hear the sound that type of ball makes as it bounces without much force. It bounced once off the table, then off the wall onto the floor where it did the dribble bounce off the tile in the kitchen until coming to rest on the carpet in the living room. None of what I see is related to my house.

If I really wanted to, I can vanish into this world I've built for the ball. I can get lost, staring out a window or something while not actually seeing anything because I'm in my head. I have hyperphantasia. It's seen more often than aphantasia, but it's not exactly common. It's very useful for creative endeavors, but has a lot of pitfalls; usually involving spacing out at inopportune times.

[–] [email protected] 1 points 2 months ago
  • black
  • male
  • nothing, it was just a hand pushing the ball
  • a ping pong ball
  • round, wood coloured, but thin like a metal coffee table.

I did have to think about how to put it into words, but the picture was fully formed before revealing the questions.

[–] [email protected] 1 points 2 months ago

Before reading the questions:

  • The ball was uniformly gray, with a slight shine.
  • The person was genderless and featureless. I only pictured their hand and arm pushing the ball. The moment of contact was indistinct, as if the arm was hiding the ball from view.
  • The ball was the size of a large watermelon.
  • The table was square, about 1m² , brown-gray, with four turned legs. Same material as the ball: uniformly colored and vaguely glossy.

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

[–] [email protected] 2 points 2 months 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.

[–] [email protected] 1 points 2 months 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.
