A new study has found that, on average, people can remember as many as 5,000 faces. That number comes from a group of researchers at the University of York in England. They published their findings on facial recognition this month in the Proceedings of The Royal Society B, Biological Sciences. 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. The research team tested people on how many faces they could remember from their personal lives and in the media. They also tested them to see how many famous faces they recognized. Rob Jenkins works in the psychology department at the University of York. He said the researchers’ study centered on “the number of faces people actually know.” He said the researchers were not able to discover whether there is a “limit on how many faces the brain can handle.”
