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?

    • The ball was a futsal ball, so white with green markings
    • I didn’t see the person who pushed the ball, just their hand, I was concentrating on the ball
    • The table was at about the height of a typical dining room table, it was plain wood about 1cm thick with a dark top and had fairly thin black metal legs

    I already knew the answers, for the most part. The questions didn’t cause me to add more detail, but they did cause me to reflect on the details I had chosen. So, for example, I never looked at the person who pushed the ball. Because of that, I couldn’t fill in any details about their looks or gender. But I did clearly see the hand giving the ball a push, and I think the hand belonged to someone white. Having said that, I did have to stop and think about the answer for the table. The table was part of what I imagined seeing, but it wasn’t the focus of my attention. I realized I could think about what I had imagined and the details came to me. But, it’s possible that I didn’t actually dream them up until I was asked the question.

    Also, nobody asked, but the ball fell down and hit a white surface (something like white tiles) and bounced the way a futsal ball bounces, which is to say mostly a soft “thud”.
