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?

    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.

      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.

    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!

      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.

          I remember when I was at school (this was 6th or 7th grade) and the teacher wrote y = x and drew a diagonal line on a Cartesian plane. At that moment, I realized that the world was made of math and I was enlightened. I’m not exaggerating - the experience revolutionized the way I could think.

          The interesting thing to me is that I have worked with physicists who appear to be capable of even higher levels of abstraction than I am. If I read an equation, I need to think about its geometrical representation but they claim to think directly in terms of equations. (Pure mathematics, not the letters and numbers that make up the written equation.) I believe them because they can comprehend equations much faster than I can; they and I would go to talks where the presenter just put up slide after slide of equations and I would be lost almost immediately while they were able to follow along. I don’t think that’s simply because they’re much smarter than I am, because I am otherwise generally able to match them intellectually.

            I wish I had their brain type, I struggled in math to remember the formulas. I had a great time learning it, otherwise. Calculus was awesome, I had never considered measuring the rate of change of the rate of change and I got pretty excited. Set theory was great too.

    Interesting, 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?

      Interesting. I also had only the vaguest impression of the person pushing the ball, but I definitely caught a glimpse before the ball rolled off the table. Slacks and a blue shirt, that was about it.

      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.

    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?

      I have aphantasia, and people really struggle to comprehend what it means or what it’s like. Now to be fair, I don’t really comprehend how people without aphantasia think or process things either.

      1. Were your front forks resting on the ground, or up in the air?

      No idea, all I could think was that the front tire was missing, it didn’t occur to me to think how that affected the bikes position.

      1. Was there any other damage done to your bike or to the lock?

      I didn’t think about there being any damage.

      1. Are there any other bikes nearby? People nearby? Security cameras that might have caught the crime?

      I had just thought of a bike rack with only my bike, no people or other bikes nearby. Looking for security cameras seems obvious now that you mention it, but I didn’t think of that. If you had said “what advice would you give if your friend walked out and found their bike had been stolen/vandalized” I probably would have thought of that, but trying to think of an abstract situation is much more difficult for me.

      My mental image of the bicycle changed as each detail was added, but sometimes the detail changed the image (the handlebars were straight until you said they were dropped) and sometimes the detail didn’t exist; the dropped handlebars were wrapped in handlebar tape, but that tape didn’t have a colour (not sure how to explain that better) until you mentioned it was black. Most of the details “added” something to the scene rather than “changing” an assumed detail.

      The “front forks on the ground” question was particularly interesting to me.

      The bicycle started with two wheels, and front wheel just sorta disappeared from my image when you mentioned it was stolen, but the front fork remained floating in the air as if there was a wheel still supporting it. But asking the question about the forks on the ground made gravity exist, and then there had to be a reason it was floating, which became it was being held up by the U-Lock.

      I seem to imagine scenes with few superfluous details that mostly includes only what is mentioned or implied by the narrative. But it’s super interesting to me what details we’re in fact implied.

      The ball on the table was similar. The table was at waist height to the person, and the ball had a specific size of roughly the size of a racket ball because it had to be something that could be easily pushed. But the person pushing it was just a silhouette of a person, it had no gender, the only thing I pictured clearly was the hand that pushed the ball. It was pushed in an intentional way that made the ball roll across the table away from the “person” (as opposed to bouncing, or pushed sideways)

      The table was just an elevated plane it had no texture, or even legs supporting it, (probably because there was no ground for those legs to be on,) it didn’t go on forever, you could see the end of the table, but it also didn’t have a size.

      Also conjuring up unnecessary details is a hyperphantasia thing, not doing it doesn’t mean you have aphantasia.

    Colorless ball, around the size of a tennis ball on a colorless round table. Person was colorless, genderless, and generally without any distinctive features.

    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.

      My brother in Christ you have described almost the exact same specs I visualized. The only difference is in the level of resolution of my “scene.” And by that, I mean essentially I did a few more render passes in my head to anchor everything you’ve written within a sort of Impressionistic, highly softened, out-of-focus backdrop. I saw hints of shadowy cabinets, the concept of a darkened kitchen out of sight. The shape and finger placement of my slightly more textured, clothed yet featureless male. The gray-brown feeling of a floor below, a dark white ceiling above, and the faded glow of sunlight through an unseen dining room window grazing one end of that oaken table.

      But the basics … They’re the same, and before being asked to recall them. Damn.

    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

    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.

    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.

      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.

      • 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

    I’ve noticed that after getting older, suffering several concussions, a short spat with drinking, and COVID that my ability to picture things in my mind has degraded a lot since childhood.

    Does your ability to imagine things naturally decline? I remember as a lad I could vividly imagine the feeling of things. My imagination was also much more colorful. But I could never see things in 3D like some people can (I’ve worked with some really talented tradesmen/machinists who can like assemble or fold or machine a piece in their mind, I don’t know maybe that’s just practice)

      Mine got better as I got older. Especially after some experiments with psychedelics. I didn’t think I was able to imagine a 3D object in detail, and for most of my life I wasn’t. But then I had a shroom trip in which I was able to freely rotate an imagined 3D object. Even render an object in my mind based solely on touch.
      Afterwards I went back almost to normal, but not completely. It’s like I learned to use some previously inactive part of the brain.

    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 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.
