Web Desk: According to a recent study, on average, people are capable of recognizing 5,000 faces.
The research department studied participants on how many faces they could recall from their personal lives and the media as well as the number of famous faces they recognized. Our facial recognition abilities equip us to deal with the thousands of faces we encounter.
The results provide a baseline with which to compare the “facial vocabulary” size of humans with facial recognition software that is increasingly used to identify people at airports and in police investigations.
For the study, participants spent an hour writing down as many faces from their personal lives as possible, including people they went to school with, colleagues and family. They then did the same for famous faces, such as actors, politicians, and other public figures.
The participants found it easy to come up with lots of faces at first, but harder to think of new ones by the end of the hour.
The participants were also shown thousands of photographs of famous people and asked which ones they recognized. The researchers required participants to recognize two different photos of each person to ensure consistency.
The mean age of the studies participants was 24 and, according to the researchers, age provides an intriguing avenue for further research.
The results showed that the participants knew between 1,000 and 10,000 faces.
