It's a real phenomena. Mental imagery corresponds to voluntary activation of the visual cortex[1]. The quality of the self-reported imagery corresponds to the degree of activity in the visual cortex[2] while imagining some visual scene. People with aphantasia have little to no visual cortex activity. [1] https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4595480/ [2] https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8186241/

I'm familiar with these studies but I don't think you can assume that activity in the visual cortex is phenomenal experience. I'm sure there are differences in self-reported aphantasics and people who don't claim to be aphantasics, but I don't think the existence of differences proves there is a difference in phenomenal experience.

Prove is a strong word. But it supports the existence of the condition as it coheres with our scientific models of visual experience. You can always reach for obscure philosophical puzzles about phenomenal experience to try to invalidate the science, but at that point you're just having a different debate than the rest of us.

I've got a moderate form of Aphantasia, where there are images in my head, but I'm unable to fix them in place and extract information from them. So I might think you have green eyes, but if you tell me they are brown, I wouldn't be able to refute you from my own memory. Practically, it means I'm rubbish at remembering people. I've developed some techniques that help, but if someone changes their look significantly,…

> Practically, it means I'm rubbish at remembering people. I've developed some techniques that help, but if someone changes their look significantly, it's very hard for me to identify that it's the same person. Do you perhaps have a mild form of face blindness?

I would tentatively suggest OP does. I hace aphantasia but meet a lot of people for work and have a very good memory for names once I see a face.

Aphantasiac here, happy to discuss or answer any questions

Can you complete tasks like answering the question "a square shaped piece of paper is folded once diagonally so two previously opposite corners are now on top of each other. Does the distance between the other two corners change during this fold?" I think most people would answer this by just imagining it, but I'd think the way I've described it is pretty hard to follow if you can't picture it. If you can answer the…

(Also aphantasic)

I think about the axis on which the fold is performed. Because of “square” and “diagonal”, for the two corners to touch, the fold axis must lie on both of the “other two corners”. A reflection about an axis does not change points on the axis, both points are unchanged, so their distance is also unchanged.

I think this is cope to avoid the realization that some people are walking around with drastically different life experiences.

I think a lot of people that can "see" in their mind are over-estimating their ability and a lot of people who can't are under-estimated their ability. It's probably a spectrum like a lot of things are, except in this case it is exceptionally hard to to know where you fall on it. The gap may not be as wide as it sounds. Almost everyone is still a functioning thinking human afterall. If the gap were so wide it seems l…

But there are obvious giveaways. Among your friends and colleagues there are people who can’t sing and people with perfect pitch perception despite no training, ones that can barely coherently speak but can write beautiful prose and vice versa, some can stare at code for 12h straight while others find the sheer idea of it horrifying. There’s people who believe in ghosts or even believe they’ve seen ghosts while others are grounded and rational. People with photographic memory and people who cannot recall what they were doing 5 minutes ago (me). The list of distinctions could keep going forever. Everyone’s good at something and shit at something because everyone’s mind is different. It’s silly how most people completely underestimate the diversity of human internal experience - maybe this type of close-mindedness is part of it too.

I still think this is fundamentally about how difficult it is to describe qualia.

Yeah I agree - how would you ever know if this is real or if it's just some people saying "sure of course I can visually imagine things, just like dreams" and other people saying "omg I can't visually imagine things at all, it's just like dreams". I guess you can maybe do better than nothing but it doesn't sound like they have got very far. Also... > Why This Matters Come on guys at least try.

Except, as someone with aphantasia, I see things in my dreams, so I know that seeing things is possible with my eyes closed. I don't do that when imagining in a waking state usually. Except I have once, so I also have direct experience with a very clear and vivid distinction between the states.

When you look at something and close your eyes, do you also not "see it" immediately after?

I am fully aphant and the only thing were this happens to me is highly stimulating content. I remember after endless counterstrike rounds on LAN parties, when I closed my eyes, I would still see images from the battles. Porn also does this. But normally that doesn't happen. When I close my eyes, I see the inner of my lids. And I could never control what I see.

It has been a lot of fun talking to those who are Aphantasiac. I am the complete opposite to the point where I think almost exclusively in imagery and when talking to folks I translate visuals to words on the fly. For a long time when people said that they saw black when they closed their eyes I assumed that meant that they choose to "see black". This is less about being able to see and more how we utilize that.

So whenever I chat with someone with is Aphantasiac being able to compare and contrast has been a treasure trove. Hobbies, careers, romance/relationships, what we like to read/watch, what we are good and bad at. Having our two extremes allow us to do rapid research see what is opposite and what isn't.

And then in the same way I will describe smells by how they look like they will describe stuff to me that I struggle grasping without visualizing it and that is a joy.

I'm not sure if people overestimate it either, some people just have strong memory and powerful mind's eye. My memory is probably from early trauma and represents the extreme other end. If anything it can be a detriment sometimes, I'm not sure a super powerful ability to picture stuff really impacts day to day living for the average human in history. There's no reason for it to disappear evolutionary if it's not a big disadvantage.

As examples I don't listen to music that frequently, I just listen in my head. I can hear songs pretty much completely in my imagination. I'll forget lyrics consciously but letting it play and zoning out the proper music and words appear at the right time. I can also watch days of kindergarten(or any grade) like it's video.

If people are trying to do that and can't tell a single visual detail from a memory or hum a passage from a tune I don't think it's a communication problem, there's just a real difference in experience. To be clear from my personal experience not being able forget stuff or not picture stuff you dont want to sucks. And I have some pretty bad tunes upstairs.

It kind of becomes a set of math facts, and my brain does this spatial thing where I "feel" like I am doing the task with my hands even though, of course, I am not. I have a really good spatial sense. I can pretty reliably draw floorplans of places I have spent a couple days in, at least in spatial relation if not exact size. I'm very good at identifying potential furniture reconfiguration of rooms. With my wife it is an interesting dynamic - she has such a rich inner visual life that for something like thinking about a new piece of furniture, or a move of existing, she needs me to tape out the new layout. Her visual memory of the space blocks here from imagining the new possibility, or it is so deep that she need to reconfigure everything visually. I just am aware of the alternative

Does it apply to audio as well? If you think of a song you know well, do you feel like you "hear" the music in your head, as though playing back an audio file? If you think of a movie scene you've seen, what is that like? Can you recount what was in it, even if you can't "picture" it? Or does this also prevent you from recalling the details of the scene?

Not the person you asked, but a fellow Aphantast: I cannot imagine visually at all. End-of-Yoga-class imaginary journeys are completely useless for me. I'm also faceblind. But I can imagine music I'm familiar with without any problem, and have a inner monologue (it blew my mind when I learned that some people do not). Also I have visual dreams, but nowhere near to the level of details that I have heard other people describe.

I image a movie scene: There is a man sitting at a table in a cantina. He has dark hair, slightly rugged clothes. Standing next to his table is a little green alien that targets a blaster at him. The person is sitting low, at an angle that prevents the alien from seeing that he has drawn his own blaster below the table. I know all of this, but I have no visual image of it. If I had to draw what I see in my head it would be a blank piece of paper with arrows pointing at certain points, labeled with "Han", "Table" and "Greebo".
