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?

      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.

        I’m sure it depends on the extent of the unnecessary details Thinking the ball is red is surely not hyperphantasia.

      This was fun to read. Everytime I read a new detail the scene in my head changed :)

      I’m aphantasic. You can say “picture this” followed by whatever you like. It’s not possible for me in any way. Growing up I honestly thought “picture this” or “close your eyes and see” was just metaphor. I legitimately didn’t understand other people can see things.

      My mind has a verbal descriptive stream, and I’m good with muscle-based or proprioceptive spacial memory, and the two combine to handle most things, but nothing visual. So like I can easily describe things from memory or from an idea, and it’ll be fully consistent, but not something I see.

      If you have aphantasia, and not just hypophantasia, it makes no difference how much detail is provided, there’s a total, fundamental, inability to visualize things.

        If someone told you to study a ball for 20 seconds and then close your eyes, then asked you immediately after you closed your eyes what colour the ball was, could you answer? The second something disappears from your visual field, is it gone from your “mind’s eye”?

        What’s interesting to me about this is that the way our visual field works involves a lot of fantasy. Like, our minds are convinced that we’re currently seeing everything in front of us and most of it is in focus. But, in reality our eyes can only really see a tiny amount of the world in full focus at once, but they’re constantly flickering around filling in details. This is why some optical illusions are so strange, because they show us that our visual systems are taking shortcuts and what we think we see isn’t actually reality. It makes me wonder if people with aphantasia actually “see” the world differently too.

        So as someone who coaches sometimes I have to ask. Can you imagine and feel body movements? Sometimes I’ll ask someone to visualize themselves performing an action before they do it.

          Not really, but typically if I can see someone else do a motion I can self-insert the movements I’d need to make to duplicate it, so that might just be a disused function for me.

          Although that’s a good question, because I do have special memory that I use for a lot of things, and it involves movement, but maybe not in the same way someone else would (eg I can count the windows in my place by simulating a walk through my house and “opening windows” like I do on nice mornings, but I often forget about out-of-the-way non-opening windows because they aren’t part of my muscle memory)

          I’d imagine thinking through the thought has around the same mental impact. But that would be interesting to research as that advise always helped me massively in tennis.

            In my experience people have a hard time running through a checklist in their head. That’s why just imagining the action is so helpful, since you don’t have to think as much. Or in my experience, the less you think about it the more natural the movement becomes. Like you can practice the action a bit but you need to eventually just do the action.

      Interesting point and I’m glad you made it, with a thought (?) experiment to check.

      I think I am somewhat aphantastic, but not officially diagnosed.

      Tap for spoiler
      1. Front forks down.
      2. No other damage.
      3. No other bikes, bike racks, or even street furniture. But as I read this question I retroactively added in the bike rack and street furniture outside my hometown’s library.

        Interesting, I was also thinking of a nearby library when I came up with the scenario. It sounds to me like you don’t have much aphantasia if you thought to have the forks down, most people I think just deleted the wheel and didn’t think of how that might affect the bike. Either that, or you have a lot of experience seeing bikes with stolen wheels and you naturally picture it the way you normally see it.
