Look up memory castles

so you're saying people with aphantasia test worse for memory?

Depends on whether the tests are general or if they give a different score for spatial, semantic, and episodic memory.

I've known about aphantasia for a long time, but there is one question I keep coming back to: Is it a skill issue? When I was in second grade, our teacher asked us to close our eyes and imagine a pretzel. I closed my eyes and tried to will a pretzel to appear as an image, and I failed miserably. All I saw was darkness and faint squiggles. I didn't understand why so many of my classmates said they could "see" the pret…

At best, what you're describing seems like a skill issue with the people describing it. Using multiple different metaphors that imply the thing you're saying is unrelated (mind'seye, visualization, image, etc) is just bad communication.

I'm not making any argument for or against your hypothesis that everyone can actually do it but might just struggle. I just find it pretty confusing to even understand what anyone is talking about with this sort of thing to the point where I genuinely have no clue of I can do it or not. It seems like there are so many descriptions that to me seem conflicting that I don't know if I'm doing the same thing or if I'm just doing some crude approximation because that's all I'm capable of.

> but there is one question I keep coming back to: Is it a skill issue? Every time the topic of aphantasia comes up, this question always gets asked. I get that it's apparently inconceivable that someone who doesn't have aphantasia just assumes that everyone who claims they do is just doing it wrong or misunderstanding what the mind's eye is or that the claimant's own experience is just flat wrong. It's dismissive an…

This same behaviour does actually persist in other areas. I'm colourblind, even as an adult I have other people argue that perhaps I just don't know which colours are which rather than have a problem with the mechanism within the eye for detecting them.

The ultimate test is having them draw a picture. If they can visualize imagery then they should be an excellent artist. If they are bad at drawing, then they must have aphantasia.

Right now, while staring at a blank wall, I visualized a red, 3D apple with a cartoonish worm emerging from it and then taking out a cleaver and chopping up the apple. It was similar in detail to what I'd see in a cartoon, but (like I said above) in another mental plane. So no, I don't think I have aphantasia.

That's phantasia, but it's not hyperphantasia. It's a spectrum. How does that falsify anything that is under discussion here? Is it so hard to believe that other people have abilities you lack? I don't have perfect pitch but I believe people can have it, because they can demonstrate it.

> Is it so hard to believe that other people have abilities you lack?

He literally said he HAS the ability. He can actually do it. It is just that he learned it at some point.

It would take a lot to convince me that aphantasia or phantasia actually exist. Let's talk very specifically about the afterimage test here. Can anyone confirm that they have this ability, which specifically is to superimpose imagined objects inside your actual field of vision? If the answer to this is yes, then okay, I guess I have aphantasia. But none of the other criteria seems to apply. I can imagine a song, and…

I agree. The afterimage test was a major red flag for me. To see something in your “mind’s eye” has nothing to do with physical vision, yet the afterimage works by exhausting some of the eye’s physical cones. It’s a confusing non sequitur and totally unrelated to the subject at hand. I have always suspected that people with “aphantasia” simply misunderstand the idea of a “mind’s eye,” believing that others can someho…

> I have always suspected that people with “aphantasia” simply misunderstand the idea of a “mind’s eye,” believing that others can somehow superimpose something onto their actual field of vision at will. Of course, this is not possible.

If "at will" is the hinging point then maybe not because the scenario to trigger the behaviour isn't clear to me still, but this is definitely possible.

I have had the superimposed belief-image confuse my spatial brain until I moved my point of view (in which the real world obviously reorients while the brain conjured image doesn't) to clear it before. This happened far more when I was younger than now as an adult, but it very much still happens.

The very last time I recall this happening was at my former home during a strenuous house move. I was on my back for a breather between boxes and a delay getting the car around gave me some time for my mind to wander, which it did on that occasion to thoughts about how very old buildings with column supports used to look. By the time I needed to move the next box I had to shake my head to de-conjure the little stone plinths that had appeared in my vision from my imagination trip.

At the end of the day, it's the "Is your green my green?" question and is unknowable.

You cannot describe something that someone lacks or has a substantially different subjective experience with, truly.

The best we can do is show that the effects of your seeing green are the same as mine (biologically, behaviorally, etc).

If you're curious about the broader subject, would highly recommend reading An Anthropologist on Mars.

Sounds like you have aphantasia but you’ve convinced yourself that you don’t. Here’s a simple question: how close are your waking visualizations to images you see in vivid dreams? From what you’ve said, assuming you do experience vivid dreams sometimes, it sounds like the answer is “not very”. Many people without aphantasia report waking imagery quite close or at least comparable to what they experience in dreams. If…

Few people routinely mentally visualize with the same breadth and vividness as dreaming, unless perhaps they have poor dream recall or don't dream very vividly. It's probably more rare than aphantasia. On the flip side, this means with some introspection and reflection most people can appreciate how those with aphantasia think; most people use a mix of mentalisms for cognition, it's just not as apparent as visualizat…

A fascinating thing about dreams I realized as a midlife adult after getting into ML is how coupled brain storage : dreaming is.

Example: If you appreciate a good sunset, have you ever had a dream about just a sunset? With the full color experience and wonder?

If not (I haven't, and most people I ask haven't), isn't that weird? Because presumably you've seen hundreds and can imagine exactly what they look like if you focus.

But you know who do seem to dream of sunsets in their fullness from time to time? Professional artists who work with colored media.

Crazy how our jobs and most repetitive experiences influence our neurology and our dreams.

They absolutely exist. I have a VERY strong minds eye and can invent and watch movies if I want to. Once I was driving while my friend described a post-apocalyptic landscape. I was seeing that landscape and not the road. Suddenly (some part of my brain was still paying attention, thankfully) the road rushed back to me and I saw that the cars in front of me had stopped. I had to slam on the brakes to avoid an accident…

Right away the story is impossible to verify. What does "I was seeing that landscape and not the road" actually mean? You can't answer that, and neither can I. I will never, ever, know what you mean by that. I can guess, and I definitely have already done so.

This is such a weird response, what do I have to gain by lying about such an event? Why would you want to "verify" it? I am sharing a lived experience: my visual experience of the image of the dystopian landscape was so strong that my cognitive experience was consumed by the image in my mind, to the extent that I no longer saw the image conveyed by my eyes.

I suppose, hypothetically, there are people who come to HN to fib and spin tales, but I am here with no agenda other than learning and conversing.

I think you just have a different interpretation of how you "see" things. Sounds just like any other anecdote of getting distracted on the road, those can be dramatic, but nothing here points to actual visual hallucinations.

I think "visual hallucination" is something very different from the minds eye. The imagination is one source of visual experience, the eyes are another. A visual hallucination is when something goes wrong and the data from your eyes is contaminated or distorted in some way. In my case, my imagination can produce photo-realistic visual experiences which are strong enough to block out the data from my eyes. They don't mix, but I can supplant one for the other at will. If they did mix I think that would be a disorder and we'd be talking about something other than aphantasia and imagination.
