When you get acquainted with someone, you start to recognize their face pretty quickly, but if you see it the other way around, studies show It’s harder to say.
Known as the face inversion effect (FIE), scientists have long been trying to determine whether this is an evolutionary or learned behavior.
“Face processing has received a lot of research attention and is a relatively well-developed area of research, but the brain is complicated and difficult to study, so we still have a vague understanding of how face processing works,” he said. Brad Duchaine, a psychologist at Dartmouth College told DailyMail.com.
Now, a study by Duchaine’s team provides a unique opportunity to study how we perceive faces. They studied a Brazilian man named Claudio Vieira de Oliveira who has a congenital joint disorder that causes his head to rotate 180 degrees.

Claudio Vieira de Oliveira who lives with atrophied legs, his arms stuck to his chest and his head turned back, resting on his back. When he was born he was only given 24 hours to live.
Due to the position of his head, Vieira de Oliveira often sees people’s faces upside down. Researchers tested his recognition ability in 2015 and 2019.
The researchers showed Vieira de Oliveira with upright and inverted faces, and wanted to study his identity detection and matching abilities.
Upright faces were those with eyes above the mouth, and inverted faces were those with eyes below the mouth, the study noted.
The researchers determined that if Vieira de Oliveira was better at identifying upright faces than inverted ones, it would mean that recognition is based more on experience, since that is how he typically perceives people.
Vieira de Oliveira performed similarly on upright and inverted faces, indicating that both evolution and experience impact our ability to perceive faces.
When shown upright faces, Vieira de Oliveira was correct 61 percent of the time. When shown inverted faces, he was correct 68 percent of the time.
Vieira de Oliveira was born with arthrogryposis multiplex congenitaa condition that restricts movement in multiple joints and muscle weakness, and his parents were told he would not survive after birth.
He lives in the small town of Monte Santo, in the state of Bahia, in northeastern Brazil. He has walked on his knees since he was seven years old and his mother taught him to read and write.
However, Vieira de Oliveira currently works as a tax accountant, has given motivational speeches and written an autobiography.
“Prior to this study, nothing was known about how a person who has seen many faces that do not match their own face behaves around upright and inverted faces,” Duchaine said.
“These results indicate that people with typical face perception are extremely good with upright faces, both because of the experience they have had with them and because their visual systems have processes designed to process upright faces,” he said.
They also showed Vieira de Oliveira Thatcherized facesor faces in which certain features, such as the mouth and eyes, are inverted in a vertical face or held upright in a reverse face.
When looking at ‘Thatcherized’ faces, Vieira de Oliveira obtained better results when seeing upright faces with altered features.
The researchers said they don’t understand why Vieira de Oliveira recognized Thatcherized faces well, but they assume it has to do with a different visual mechanism besides detecting faces and identities.
“Almost everyone has much more experience with upright faces and ancestors whose reproduction was influenced by their ability to process upright faces, so it is not easy to separate the influence of experience and evolved mechanisms adapted to upright faces in typical participants,” Duchaine said. in a press release.
Researchers want to continue learning about the differences between how evolution and experience influence how people perceive faces.
They also want to study the different judgments people make when they see faces, such as how they perceive attractiveness and trustworthiness.
