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 have aphantasia. The reason this experiment works is because someone with aphantasia will logically think about what they’re being asked, but since they’re not really “picturing” it, they won’t have any answers about details. Color, type, and size of the ball? I have no idea, that information wasn’t relevant to my mental checklist. For me, it really does work like a checklist. My brain supplies exactly zero imagery. For some people it’s more like a spectrum, where they might be able to have a hazy picture with minimal details.
But aphantasia is 100% real. It’s just hard for people to believe it because it’s so foreign to the way they’re used to thinking, in the same way it sounds unbelievably exhausting to me that regular people are constantly creating movies in their heads.
