- What happens to the ball? It rolls of the side of the table.
- Color: I didn't imagine a specific color
- Gender: I didn't imagine a specific gender. Most of the person was "out of the frame"
- What did they look like: Again, most of the person was out of the frame, they were just kind of a gray silhouette
- What size was the ball? Like a dodgeball I guess?
- What about the table? Very minimalist square table made up of five rectangular prisms (the surface and four legs). No specific material, uniform texture. I imagined everything in isometric perspective.
This is what I recall from my first time imagining the scenario, I'd have to imagine some more if I wanted to give specific answers.
With all due respect, I don't believe aphantasia is a real thing. The way people imagine things is so varied, weird, strange, and unique that I don't think it makes sense assigning labels. Different people will give varying levels of detail to different parts of their imagination based on their past experiences and knowledge.If you ask someone to imagine a chessboard, someone who plays chess might imagine a specific opening or valid board state, while someone who doesn't might just have a vague blob of chess pieces on a board.
Even with your ball on a table experiment, the experiences people have had throughout the day may give more or less detail to the imagined scenario. I'm fairly certain that the reason I imagined everything so abstractly is because recently I found an artwork with a similar minimalist isometric style that I liked a lot, so it's kind of floating around in my subconsciousness and affecting how I imagine things.
