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?

  • 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.

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.

I think my brain might just be lazy... I skipped over the entire walk to the table part. And just imagined a detached arm pushing the ball on a surface, until it rolled off the surface and that was all.

[–] reinei 2 points 2 months ago (1 children)

Thanks for sharing this as well! I also just imaged a detached hand + short bit of lower arm pushing the ball (for which I did imagine it to be of a gray shiny metal slightly larger than the hand)!

And I also imaged a super plain square wooden table so when the questions about the person hit I was super confused wether or not this counted as aphantasia or not (because I am fairly certain that I don't have it...)

You basically just expanded on everything I imagined. I couldn't have described it better.

It does, it's a studied and proven condition. No idea why you wouldn't believe it lol

Labels should always be used with caution, but for me, learning about aphantasia led to me reconsidering the ways in which I imagine things, and this had a beneficial impact on how I communicated with people close to me. For example, I seem to be an odd mixture of relying on visual stimuli for thinking (so I have visual reminders all over, and reading complex info is way easier for me than hearing it), but also seem to lack the ability to visualise. This means that if my partner asks "hey, do you remember which drawer the mini screwdrivers are in?", I would usually be unable to answer, despite being able to walk in, take a glance at the drawers and go "that one, there". We didn't realise how frustrating this was for both of us until we reflected on the possibility of me having aphantasia. Whether I do or not doesn't matter. More relevant is the fact that now, when he asks me questions of where things are, it'll often be accompanied by a photograph of the location, which drastically improves my ability to recall and point to where the item is.

To some degree, I agree that it's nonsense to assign labels when in nature and in humans, variation is the norm. Certainly it can lead to reductionism and ignoring wide swathes of that variety if one is on a quest to sort people into boxes. However, there is still a lot that we don't know about how the brain works to process things and labels can be instructive either in researching aspects that we don't yet understand, or for regular people like me who find benefit in a word that helps me to understand and articulate that there are ways that my partner thinks and processes information that seem to be impossible for me to emulate. "Aphantasia" helped both of us to be more accepting of these differences.

Framing a phenomenon as either real or not isn't especially useful though, largely because of the ambiguity in the phrasing. An example in a different domain is that I've seen a wide variety of people claim that they don't think autism is a real thing. This tends to be received as offensive to many people, not least of all autistic people who feel like their lived experience is being directly attacked and questioned. Sometimes it is, and their anger is justified. However, I've also seen the "autism isn't a real thing" sentiment come from (often autistic) people critiquing the label and how it's used, especially in a clinical context. They argue that it perpetuates a binary framing of autistic and not autistic, which further marginalises people who do have a diagnosis, and isolates some people who have autistic traits but are overall sub-clinical in presentation (who may have benefitted from understanding these traits from an autistic perspective). Regardless of one's view of the arguments, it's pretty clear that these are two very different stances that might be described by "autism isn't a real thing".

I make this example because debating of the utility of labels can be a great and fruitful discussion that helps to improve our understanding of the underlying phenomena and people's experiences of them. Framing that debate as what's real or not can lead to less productive arguments that are liable to cause offence (especially on the internet, where we're primed to see things in a more adversarial manner)
