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?

    I’ve put some effort into improving my visualization since learning about aphantasia. Upon reading the prompt, I was able to imagine a colorless ball, but with shading to indicate a 3D shape, like a preview render in a CAD program. That’s progress! It didn’t have a size inherently. For the table, I could picture a white, rectangular plane hovering in a black void. If it was a normal dinner table size, then the ball was something like a softball or basketball.

    And that’s it. That exhausted my ability to visualize. No person, no push, no motion. Best I can do is to see the white rectangle after the ball has rolled off of the edge.

    The ball was red, like a red rubber ball. The person was sort of indistinct from the neck up, it was more like my view was focused on the ball itself and didn’t see a face, but it was a man, wearing a white shirt and dark tie, and dark pants. The ball was about the size of a baseball, wasn’t completely smooth and shiny, sort of a matte with a slight grippy texture. Table was square, wood, like a medium brown color. The ball rolled off the table and bounced a few times.

    All these decisions were automatic when reading the prompt, it’s what I saw.

    I’ve just become aware of aphantasia myself, I have a few family members who have it apparently. I was talking to my BIL about it the other day, I was saying how I’m a big fan of reading, but I mostly read nonfiction. He said he doesn’t read much, mostly biographies, but fiction doesn’t do much for him because he can’t picture anything in his head. I can picture everything in great detail when I read fiction. Its interesting because our minds work very differently

    The ball had no color, the person had no gender or specific form other than vague shapes (the hand and arm being the most visualized), no memory of deciding any specific clothing, the ball was the most fleshed out part where it was the size of a softball. The table was square with vaguely wood coloring. The size was about 2 ft by 2ft maybe 3 ft high.

    I did not already know most and I did not retroactively change them. I gave answers as I remembered my visualization.

    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.

    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.

    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.

    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.

    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.

    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.

    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.

    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.

    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.

    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.

    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.
