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.
