I think I have aphantasia

Post Reply New Topic

I just found out about this on another post when someone mentioned they had it.
Doing some reading it seems to match me nearly completely.
If I try to picture something in my head, I don't see anything. Closing my eyes I just see irregular darkness (this looks sort of like a tunnel system to me, and I had all sorts of daydreams falling through it. I talked about this in another thread, but this is probably the closest I am to imagining an image).
Sometimes, rarely, I will get a flash of an image. Its dull and vague and it dissapears nearly immediately, but its there. Its like when watching a movie, and one frame is completely different and you just see it but you arent really sure. Thats what it looks like. Trying to picture something in my head gets me nothing most of the time.
Do I proobably have aphantasia or could this be something else?

No idea sorry , but this test might give you a better idea

OP, you might want to do the questionnaires here- http://medicine.exeter.ac.uk/research/h ... etintouch/

I scored 8/40 on that BBC questionnaire. I can't imagine sights,smells,sounds,taste and touch.

Another survey the OP might like to do. https://boisestate.az1.qualtrics.com/jf ... yWafcDXc69

I’m a very visual thinker but I don’t literally see images that I imagine, as if I were actually looking with my own eyes. If people could just will themselves to hallucinate then there wouldn’t be people taking hallucinogenics, would there?

Correct me if I’m wrong, but I think those with Aphantasia can’t recall sensory information at all so they remember events as essentially a laundry list of facts. You can recall images, even if fleetingly, and I presume other sensory input so you probably don’t have it. You might not remember some sensory input as vividly as some but you seem to have at least a baseline level of sensory memory.

When I first heard of aphantasia, I didn't think that I have it. After talking to others, though, I find that they seem to be able to visualize things very readily -- often in very realistic detail. For me, I can kind of visual something, but it is very fleeting and highly cartoonish at a very low resolution. The image seems to last, at best, for maybe about 1/4 to 1/2 of a second and then vanishes completely. Once visualized, for that fraction of a second, I cannot bring the image back again for quite a while.

When thinking about the example of walking on the beach and looking over my shoulder at the sun, I get a flash of a beach and then it's gone. Then a flash of water and then it's gone. And a flash of the sun, but it's gone. Trying again, there is nothing.

Oddly enough, another mathematician once told me that he wished that he had my visualization ability. He thought that I could visualize higher dimensions much better than anyone else he knew. While I don't think that I can visualize higher dimensions, I did once have a really fantastic dream that I seemed to see in four dimensions.

If I make a great effort I can only have a vague idea of a theoretical picture. That is sometimes frustrating when I read a book.

My "pictures" are more feeling, sound and abstract 3D geometrical pictures.
