If you just came into this site about face-blindness or prosopagnosia, I suggest you start either with my stone page for a brief introduction to what face-blindness can be like, or at my homepage for an overview of what pages are available on this site.



I created this page to try to give my friends and myself an idea about what I am able to remember of a face. The first examples are cartoons because they are interpreted by the brain as half way between objects and faces.

This page is only about how I remember faces. It is not how and where I look when i talk to someone. Even how I remember the faces was so elusive that I did not notice it myself until I started experimenting with it. I don't think anyone else could ever have guessed.

Have you ever looked at a faint star in the sky? You can not see it if you look straight at it, only if you look a little bit to the side. (Try it tonight if the stars are out and you haven't noticed it before. It has to be really dark. Close to a big city it is often not possible to make out the faint stars at all.) That is how it feels for me when I try to visualize faces. When I try to look straigh at the image I visualize, I see much less than when I try to look a little beside them.

In real life, I never visualize a face straight in front of me. What you see in the middle column here is what I found when I started experimenting with visualizing in order to learn more about my face-blindness.

Note that the blurring and loss of colour in objects I don't look straight at, has nothing to do with my face-blindness. Although we are usually not aware of it, normal human eyes always gives that kind of image when we don't look directly at an object, but see it "in the corner of the eye". In the same way that most people are not aware of this blurring and loss of colour, I was not aware of my inability to visualize faces straight in front of me until I recently started to actively experiment with what I can and can not remember.

What they really look like

What they look like when I visualize them straight in front of me

What they look like when I look a little bit beside the visualized immage.

On this row I wanted a photo of someone I have not actively tried to remember. In the photo is Jack Kilby. He was awarded the Nobel price in Physics year 2000. I have listened to one or two of his lectures with great interest, but I have not actively rehearsed his features.

If I do not 'rehearse' a persons features, I usually don't remember what they look like at all. What I do when I rehearse is that each time I see the person I am trying to remember (and know who it is), I will silently say to myself "This is X, brother of Y" (or my new boss, or my mother in law, or the person I talked to for an hour during lunch, or ...).

After I have done that a number of times I will have learned to recognize them, at least when I meet him or her in a place where I expect to meet them. If I don't 'rehearse' I will very likely fail to recognize someone who have been working in the same corridor as me for years (even if I meet them in that corridor).

This is Francine, my resource manager. We sit in the same corridor in the office so I see her almost every day, and talk to her every now and then. She is someone I see often but who is not a close friend. When I took this picture I had known her for a few months.

I am usually totally unable to see a real visualized face straight in front of me.

When I try to visualize her face looking a little bit beside it, I have a fairly good image of what she looks like. (At least it's good for someone with prosopagnosia.) This image fits my memory of what she looks like quite well. What I lack is her emotion. I can see emotions in a face as well as most people. I get much of the emotional information from the area around the mouth, even though it seems to be completely impossible for me to remember what the mouth looks like.
Note that the areas that I can not remember are the same areas that changes most in a face, and also just the areas that non-face-blind people use for identification.
Together with my memory of a face also always comes the memory of the voice of that person.

This is Hans, my husband

When it is someone I know really well, such as my husband, I often have a less good image for some reason. What I have is mainly the feeling that the person invokes in me.

Whether I visualize someone straight in front of me or look beside the image does not seem to make much of a difference for the result when it is someone I know really well.

This again is Hans, my husband

If I try, I can remember what some details of the face look like. It does not help much in the process of recognition though.

When I try to remember someone I know well, I think I probably use other things than the face to recognize them.




What I have tried to show here is not a complete description of reality of course.

It is only a description of how I remember faces. What other face-blind people do and do not remember can be completely different. So far I have not heard from anyone who has exactly the same experience with what they can and can't visualize / remember.

Also this is only about how I remember faces when I use them to identify someone. We humans can use faces for much more than that. We use them to read someone's feelings, to see someone's gender, estimate someone's age and so on. All these things I do as well as most people. My problem is very specifically connected with the identification of people. This is possible because the human brain uses a number of different brain-centres to process images. One of them, located in the right temporal lobe, is specifically designed to identify faces. It does nothing more and nothing less then to try to identify all faces that we see. In my brain, that centre does not work.

I think one reason that I remember faces better when I use peripheral viewing (look beside the image) could be that the brain does not recognize the image as a face when I don't look straight at it. When the image is not identified as a face it is not routed to my damaged brain centre for recognizing faces. Instead it is routed to a brain centre for general pattern recognition. That is the same brain centre that non face-blind people would use to recognize a stone or a twig. Using that brain centre I have learned to recognize people about as reliably as most people could learn to recognize a stone.
