Can you remember a face quickly and never forget it? If so, then you could be a super recognizer.

Usually it is easy for someone to recognize the faces of their family members and friends. But it could be difficult for them to remember faces that they have only seen once. However, studies have found that super recognizers have amazing face recognition skills. They can remember at least 80 per cent of faces they have ever seen. According to the Daily Mail, at least one in 50 people are super recognizers.

A study was carried out in Bournemouth University of UK recently. Researchers tried to find whether super recognizers have a different way to remember faces. They found that when these people look at faces, they spend more time looking at the person's nose. They also found that these people are not smarter than others. Their super ability is restricted(有限的) only to face recognition.

Another important finding is that there are two subtypes(子类型) of super recognition. Some never forget faces. But for some, if you show pairs of faces to them at the same time, they can quickly decide whether the faces are of the same person or two different people. In fact, many super recognizers say they are very good at recognizing faces in a crowd.

These subtypes of super recognition could be applied to many areas of life. For example, the skills could be very useful at a passport control checkpoint. Super recognizers could also help police find known troublemakers and even missing people in the crowd.
