Imagine a world where everyone looks the same and you can't recognize one person from another – even you own child! It sounds like a frightening episode from the "Twilight Zone", but it's just every day life for people with prosopagnosia, better known as "Face Blindness".

We humans use parts of our brains to see, process and recognize faces that are different from recognizing anything else in our lives, which is not surprising when you consider how important faces are to understanding the situations we are in and the emotions of the people closest to us.

In this episode, Dr. Brad Duchaine, a professor of psychological and brain sciences at Dartmouth College and one of the world's experts on face recognition, explains how how the face blind perceive the world, the strategies they use to mange their lives, and the unfortunate people who experience the rare (and almost unpronounceable) condition of "prosopometamorphopsia."

Plus, hear how "Super Recognizers" are using the opposite of face blindness to help fight crime.
