This is a thought experiment "Ball on a Table" for detecting whether someone has Aphantasia. What do you see when you perform this experiment? (self.asklemmy)

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?

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.

I also had the "I spent 23 minutes designing this scene in blender" impression of the ball, table, and disembodied hand. The table was made of light grey, the ball was made of light grey, and the hand was made of light grey

  • 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

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.

I can't speak for others, but I do if they're concepts I've encountered before. I have "default" visualizations of things that are changed if the description warrants it.
