I've got a moderate form of Aphantasia, where there are images in my head, but I'm unable to fix them in place and extract information from them. So I might think you have green eyes, but if you tell me they are brown, I wouldn't be able to refute you from my own memory.

Practically, it means I'm rubbish at remembering people. I've developed some techniques that help, but if someone changes their look significantly, it's very hard for me to identify that it's the same person.

I'm still learning how this has impacted by life, and strategies for working with it. As a simple example, my wife's family was really into cars, so when I got to know them I learned all about cars. When I met my wife, I couldn't identify a single vehicle on the road, except maybe a Hummer, but after 2 years, I could quickly pick out the make and model of 95% of traffic.

Looking back, I can see this is because rather than remember what different cars looked like, I created a taxonomy of ALL cars in my head, and became able to sort any vehicle I saw to fit there somewhere. So when I identified something, I wasn't matching it against previously seen things, but rather eliminating all the things it couldn't be to arrive at the remaining possibility.

Do you perhaps have a mild form of face blindness?
