Face Blindness
When encountering new people, the first thing we notice about is their faces. The next time we see these people, we remember them because we remember their faces. This seems like a simple _________ . It turns out, however, that when scientists investigated the brain, they found that face recognition is rather complicated. The _________ of the brain that is responsible for face recognition seems to work differently for different people. Some people have great difficulty remembering and recognizing faces, while others almost never forget a face.
Normal babies are born with a _________ ability to recognize faces. In fact, their face recognition abilities are much better than their parents. For example, most adults can easily recognize faces that _________ their own. However, they cannot easily recognize faces of people of different races. At six months, babies are highly _________ at face recognition. But by nine months, their face-recognition skills are about the same as an adult’s.
_________ , some people are not born with this ability to recognize faces. The part of the brain that is responsible for face recognition doesn’t work for them. This _________ is called prosopagnosia, or “face blindness”. People with very serious face blindness cannot even recognize their own faces. In fact, people with this status can sometimes be frightened when they look in the mirror. They don’t recognize their own face, so for a second they are startled when they see this _________ face.
Face blindness is not always _________ . Some people only have difficulty recognizing faces of people they don’t know very well. Scientists believe up to 10 percent of the population may be affected by face blindness to some degree, __________ many people with mild face blindness might not even know they have it. They have no reason to know that they are different from anyone else __________ someone points it out.
Scientists became aware of another face-recognition case in the process of researching face blindness. They found that there are also “super recognizers” who remember every face they have ever seen. For these people, it is not __________ to forget faces. Super recognizer Jennifer Jarrett says, “It’s as if their faces are __________ in my brain.” Many super recognizers don’t just recognize faces they have seen before. They know exactly where they last saw that person.
Super recognizers don’t usually feel that they have a problem. Most people with __________ to serious face blindness, on the other hand, do. There is no cure for face blindness, therefore, for the time being, people with face blindness need to find simple techniques to __________ for their problem. They can try to recognize people by their hairstyle, their voice, or their glasses. Hopefully, in the future as scientists learn more about this situation, they will find a cure.
