Researchers at the University of York in England published their findings on facial recognition that, on average, people can remember as many as 5,000 faces.
There have been many studies recently on facial recognition technology. But the authors of this study say theirs is the first time that scientists have been able to put a number to the abilities of humans to recognize faces. Rob Jenkins, leader of the research, said the researchers' study centered on "the number of faces people actually know." and were not able to discover whether there is a "limit on how many faces the brain can handle."
Jenkins said the ability to tell individual people apart is "clearly important." In today's modern world of big cities, we meet and deal with thousands of people. The study suggests our facial recognition abilities help us to deal with the many different faces we see on the screens, as well as those we know. The results of the study give a baseline for comparing the "facial vocabulary" of humans with facial recognition software.
Today, facial recognition technology is used in many ways, including by law enforcement agencies to prevent crime and violence. Governments use it to keep secret areas secure and, in extreme cases, control populations. Some governments use the software to watch people and find out where they go and what they do. Even Facebook uses facial recognition. For example, when you name a friend, Facebook technology may recognize the person's face from a different picture you had shared before.
For the human study, people spent one hour writing down as many faces from their personal lives as possible. At first, they found it easy to come up with many faces. But by the end of the hour, they found it harder to think of new ones. Their change in speed let the researchers estimate when they would have run out of faces completely. 1,000 to 10,000 faces remembered. People who took part in the study were also shown thousands of photographs of famous people. Researchers asked them which ones they recognized. To make sure they knew these people, researchers required them to recognize two different photos of each famous person. The results showed that the participants knew between 1,000 and 10,000 faces.
How do they explain such a wide range? Jenkins said one explanation may be that some people have a natural ability for remembering faces. "There are differences in how much attention people pay to faces and how well they process the information." Also it could be because of different social environments. Some people may have grown up in more populated places. So, they may have had more social contact throughout their lives.
Researchers think age may be an interesting area for further research. “It would be interesting to see whether there is a peak age for the number of faces we know”, Jenkins said. He said it is possible that we gather more faces throughout our lifetime. But, he added, there also may be an age at which we start to find it harder to remember all of those faces.
