When trying to recognise someone from far away or when their face is obscured, the brain uses information from a person’s body size and shape to figure out who it is.
Scientists had previously thought recognition relied solely on facial features but the latest discovery found that working out who someone is from far away relies on other physical cues.
The finding could have implications for security and law enforcement, who currently rely on facial features for recognising people.
Researcher Allyson Rice said: “Psychologists and computer scientists have concentrated almost exclusively on the role of the face in person recognition.
“But our results show that the body can also provide important and useful identity information for person recognition.”
