If someone asked you if a tennis ball could fit into a keyhole you couldn't answer?

That's unrelated to aphantasia, and is instead related to knowledge which doesn't require the ability to visualize to apply. Any common keyhole is going to be obviously smaller than a standard sized tennis ball to any person aware of both objects. An inability to answer your question would occur if someone lacked knowledge about one or both of the two objects, or had a fundamental inability to recall information about relative sizes and shapes of the two objects (perhaps generalized to more than just those two).

  What do you mean by "obviously smaller"? How do you make that judgement without ever being told one is smaller than the other and without being able to visualize both?

    By having experience or knowledge of both objects. If you've ever held a tennis ball and have ever seen a keyhole you know which one is bigger than the other, you have no need to visualize them in your mind in order to make a comparison. So long as you can recall these facts about them, you can make a comparison based on knowledge and not on visualization. Now if something prevents you from having this knowledge (somehow you have never seen a tennis ball or a keyhole, or something in your brain prevents you from having the ability to recall facts about the objects like their sizes) then that's something else, but it's not aphantasia. Besides, visualizations aren't perfectly accurate, they are subject to your own knowledge and memories. And they can be distorted by poor recall or just the imagination itself. I'm capable of visualizing a tennis ball that is small enough to fit inside a typical keyhole, or a keyhole big enough to permit a standard size tennis ball. That doesn't make either scenario realistic just because I can visualize them.

      So do they remember the size of things in terms of numbers then do some sort of mathematical algorithm to compare their sizes? I'm trying to understand how things can be compared without some sort of internal visualization.

        Possibly with numbers. Can you properly visualize a tennis ball next to a baseball and tell which is larger? I was never much of an athlete (in the sports ball sense, at least) and have insufficient experience with either to tell you definitively which is larger (I looked it up, my guess was baseball and that turned out to be correct). The fact is that a small but still standard sized baseball is only 5mm larger than a large but still standard sized tennis ball. That is near enough that my memory (I played baseball last as a kid) could not distinguish between the size of the two objects. But now I know the fact, a standard baseball is larger than a standard tennis ball (now, don't ask me in a few weeks what the actual sizes are, I will probably forget, though I will probably remember that the baseball is larger). Another way is just having knowledge of relative sizes and the ability to perform rudimentary logic. A tennis ball feels about the same in my hand as a door knob (in terms of size and ability to wrap my hand around it, bigger than most but not by too much). A keyhole fits into a doorknob. I'd have to be really drunk to not realize the logical implication of that: A tennis ball won't fit into a keyhole (assuming both are standard sized and we're not talking about a comedian's prop key and keyhole).

        A tetrafoo is four times the size of a barbaz. Tetrafoos are pretty big things, about the size of a washing machine. Now I've said nothing specific about either these things, besides size. Can you tell me if a barbaz fits through a door? Probably. Can you see that you can reach that anwser without doing any math about how big doors and washing machines are, but just with implicit knowledge? The source of truth here is not visualization, it's knowledge. In fact, whatever you visualized, I gave you too little details so that your visualization would have to make up extra things that aren't true. You don't even know if the shape of those things is square or circular. So even if you can't do it without visualizing, you should see that visualization is really just pulling from some other source (abstract knowledge). You can bypass that step and just get to know the result, without visualizing it.

    > without ever being told one is smaller than the other and without being able to visualize both? As opposed to never having seen or been told about a tennis ball or a keyhole, and expected to know which is smaller? The idea of aphantasia doesn't imply being blind. Assuming someone is sighted, you can still see objects and internalize an order of "small to large" things without necessarily using mental imagery to make those connections. I'm not sure if I have some "kind of aphantasia" but I also don't generally visualize things in my head, instead remembering logical relations based on my (non-visual) memories.

    I'm still all in on these people thinking imagining something is a hallucination. There's no way someone can't picture their mom in their head. Yeah, it doesn't overlay my visual field, and that doesn't mean I can draw it. I really think they are being pedantic/obtuse/silly.

      uhh ... it is supposed to overlay your visual field
      - alar44 5y ago
        No, that's a hallucination.

        where else are you imagining something if not on your visual field?

      If you took a picture of your mom into photoshop and started to apply a blur filter, and reduced the contrast, how far would you have to push it before it resembled what you can call up in your head on demand?

        In my case, that comparison doesn't really make sense. Whatever "image" I have in my head has no resolution, detail, or colour; it's just a feeling, and not at all like seeing. I literally can't imagine what it's like to have a vivid imagination because to me my perception of reality and whatever I can "imagine" are as obviously different as black is from white. I could never confuse one for the other, and I don't know how they can even be compared.

    Knowledge of the mesh, and spacial awareness, both of which has nothing to do with seeing an image.

If I asked you that question would you visualize a tennis ball next to a keyhole? I would not. I'd answer based on what (to the best of my understanding of my own thought process) is something more like a rough tagging and comparison of "tennis balls are roughly this big" "keyholes are roughly this big" -> "the one is too big to fit." Similarly with something like comparing an elephant to a train. I'm not picturing the two next to each other, I'm trying to remember roughly how big each is.

  Yes, I would visualize a tennis ball near a keyhole. Another question might be why does a key fit in keyhole and a penny doesn't? A key is bigger than a penny. Or how did this tree do that damage? https://miro.medium.com/max/738/0*V3lJsXAHSDxqXgxf.jpg https://miro.medium.com/max/738/0*V3lJsXAHSDxqXgxf.jpg

I couldn't be aware of seeing such an image, but factually I can say a normal tennis ball does not fit into a normal keyhole. Then again, there's Alice.
