I wonder exactly how we recognize people.

Last night, I recognized someone I had only met twice before, and I recognized her when she was too far away for me to really pick out any details. But my brain somehow knew for certain who it was less than a second after seeing her. It almost came at the same time as the knowledge that I was seeing someone. Something to do with an overall impression of shape/color/movement, or something.

Pretty neat.

I'll be majes knows something about this. It seems to be the kind of knowledge he would have.

Ok, so actually, yes, that is something with which I am familiar. I've read alot about this in regards to teaching computers how to recognize people by their faces. I recently watched a show about this that had John Cleese in it. It was called the human face. More info on that can be found here. Its a very interesting topic; strong evidence indicates that our ability to recognize others has little to do with exact recall, but rather with a culmination of exaggerated feature memory, mixed in with associated feelings, colors, experiences, and even smells. Our brain creates a complex linkage between all these things and by this is able to distinguish people very accurately in a fashion that is still far beyond the abilities of even the best existing computer programs.

"exaggerated feature memory" is key

That's how memory works the strongest, when there's an exaggerated feature that sticks in your head. It works with items and studying, recalling names and such as well as faces.
