People's ability to "hear" music ranges from nothing at all to being able to "play back" close to what they heard. For my part, I have aphantasia, I can't hear the sound I heard, but I can "play it back" in my own voice (which is distinctly less pleasing).

As for movie scenes, I rarely tend to remember specific scenes - I tend to remember concepts and dialogue - but when I do remember a scene, I can often describe it in detail, and I can sketch out scenes, be it from movies or real life, that I remember well with a lot of spatial detail.

I suspect I probably do remember less of visuals than people without aphantasia because I don't really get much value from it, but I definitely can.

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".

As someone who is close to the aphantasic end of the spectrum: for me, it does not apply to audio. That difference is how I came to understand aphantasia better: I can very concretely hear sounds and music in my "mind's ear" in a way that I can't for vision.

I'm a musician, but don't "hear" music in my head. I have an extensive memory of lyrics, and can guess the next notes of a song, but I use my inner monologue to sing or hum it in my head, I don't hear it. I can recall the visuals of a movie scene similar to how I can tell you how my office is organized. It is a spatial memory of where things are and aligned with each other. I don't replay the scene in any sense of the word

Aphantasic here - I constantly have music playing in my head to the point of it being slightly annoying. If I really concentrate, I can separate out the parts like stem separation, but generally it's a fairly high fidelity recreation of the most prominent parts. There was a brilliant thread on Mastodon a couple of years ago where people (mostly musicians) were describing their inner-music abilities - mine turned out to be very ordinary. The only time mine ever approach what many of the others described is when I'm very slightly stoned - then my brain starts to compose original music at extremely high fidelity in basically any genre. I just wish I could get it out of there.

I have an inner monologue, that is the extent of my inner senses.

Not GP, but fully aphant. No I can't do that. When I close my eyes, I see the inner of my eye lids (red / brownish). That's it. Nothing comes up, even if I try to remember the face of my mother.

Nothing, no

Those don't sound to me like aphantasiac properties. possibly related, but sound like other memory topics. Especially the first one

For my part (as someone with aphantasia) my proprioception is good, and to go further, my sense of space and my spatial reasoning is well above average.

I can also draw what I can't see pretty well from memory.

Proprioception is good. I was a fairly accomplished high school and college club athlete in sports that require body parts to move out of visual range

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.

The image? no - the after image of the light on my retina, yes. But as soon as that fades there is nothing

When I learned through my sport career that visualize the race actually meant visualize and not just talk it through with your inner monologue. It was deeply reinforced when my wife first told me she sees an entire movie when she reads books.

She's 5 ft tall, sharp features, curly white hair. i can remember imagery facts, but have not visual memory

I have total aphantasia and this is how I usually answer: it's like having a picture of my mother in my head, only for it to be obfuscated by an opaque veil, and there's a system in my mind that can peak behind it and feed me informations. In the end: I can never visualise her, but I can "query" informations, and when I see her I match her immediately with what I know her to look like.

This is not a memory nor a detail recall issue. The visual part is just not there, but I know how my mother looks like :)

Not really how it works. I can describe an apple to you in great detail. I cannot imagine all of those things I described in a coherent image in my head. Personally sometimes I'm able to picture pieces or aspects of it for flashes but I cannot see an apple in my head.

yeah looks like it triggered a keyword filter to mark it as dead to me. Or a few people flagged it.

Either way it seemed relevant enough to me that I vouched for it.

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

(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 can't visualise things either and this is a task that my brain just solves for me analytically somehow. In this case I had to re-read it a few times and then knew the answer. I struggle with visual navigation but my brain compensates this with intuition (or whatever we want to call it) so I never really got lost but I'm unable to guide other people because that usually requires visual imagination (map, landmarks etc.)
