I’ve read tons of these and still have no idea if I have aphantasia or not. I can’t understand whether people just have different ways of describing what’s in their minds eye or if there’s really a fundamental difference.

The test is this:

Close your eyes and try to visualize an apple. Do this for 30 seconds or so. Try to visualize the skin, the reflection, the texture, the stem, the depth, etc. Try to hold a stable mental picture of that apple.

After the 30 seconds, rate your ability to picture the apple from 1 to 5, where 1 is complete inability and 5 is as if you were looking at a picture of an apple for those 30 seconds. 1 is aphantasia.

Another idea is to recall a vivid dream you had. I think most people would describe it as being part of a movie or reality. While awake, are you able to recreate scenes in vivid detail as if you were dreaming? 5 for complete parity and 1 for not at all. 1 is aphantasia.

But what does it mean "visualize" ? I can "think" of an apple and all it's detail, but I wouldn't describe any visual sensation. If I had to draw the apple I could draw it detail, right down the the variation in colors on it's skin. But no sense of this experience feels like a visual sensation. It feels like "thinking". To me, the act of closing my eyes emphasizes that this isn't a visual sensation for me, because with my eyes closed, I see darkness.

Bring a picture of an apple up on your computer screen and look at it for 30 seconds. There is a fidelity to that image that includes the color, texture, stem, shape, reflection, etc.

Now close your eyes and try to picture an apple for 30 seconds. Is the same experience as if having that picture in front of you? As in, can you picture, in your minds eye, an image of an apple as if you were looking at on your computer screen? On a scale from 1 to 5, where 5 is complete parity as if you were looking at it from your computer screen and 1 for no visualization possible, what is your ability to do so?

It sounds like you're a 1, as in you have aphantasia.

I know it sounds crazy but I think there really are people who can visualize that apple.

Note that inability to visualize doesn't mean you can't recognize or differentiate one apple from another. It doesn't mean you can't draw that apple from memory, in perfect detail. It doesn't mean you can't describe or recreate that image of an apple. It mean that you cannot literally have an image in your minds eye of that apple.

Based on what evidence?

The article goes into the history.

Here's an article I found recently:

I am exactly like this. Great description.
