Very few people have the ability to remember Jennifer is a person look in the crowd even see for a moment and still remember everyone in there.
In fact, she almost never can forget a face.

“I met many people in the first few weeks, and I remember each person a matter of time how short encounter. Then I met them at a party and they do not remember me. I think “This person actually took.” I can not believe people are pretending not realize, when we met in the 30-second self-service restaurant three weeks earlier.

Many years passed, impressed on her face that is not changed.

She describes some of whom she met only see a few times as a child, on the subway, and now after more than 20 points in her hair was silver, and knows exactly who she is.

“People can face their older but still look so for me,” Jennifer told BBC. “They’re no different in my eyes even as a child or the adult. I do not understand why my brain position can skip this step he jumped.

Those super-identification can recognize the faces were blur.

Jennifer’s situation sounds like a party or tips to eat, or maybe it would be in business, but it means more with the scientists.

Her ability can help the researchers to investigate the situation in the opposite - the people infected blind identification, ie not recognize familiar people in the crowd.

Claire, 49 years old, mother of four children, fell into that situation. She was encephalitis virus in 2004, and severe memory loss and can not recognize faces. Even she can not recognize their children if they go with a sure you, or frequently startled when he saw his shadow in the mirror.

In fact, there is a spectrum in the ability to identify, Brad Duchaine, from the Institute of Neuroscience awareness and research center blindness identified in the University of London, said.

People like Claire infected blind identification of damage loss from the brain. But there is one less serious than other forms, but also much more common. For every 50 people is infected with a blind person can identify light, but often they do not know that. At the other end of the spectrum is the ultra-identification, the group that scientists are studying.
