The chimpanzee recognizes faces like human
The ability seems to be inherited from a common ancestor.
Human understands the faces faster and in a different way than other species. previously this has only considered as a feature of ours, but now its turned out, that also chimpanzees recognize faces human effectively.
The japanizes Masaki Tomonago and Tomoko Imura made this case clear when they taught three females chimpanzees to look for example cars, bananas, and faces among other images. The Chimpanzees found the faces of their own species quicker than other images.
upside down the face is not visible
In the human, face recognition is based out on a quick perceiving the whole picture, and the same seems to be valid for chimpanzees as well.
Just like humans, chimpanzees perceived faces considerably worse, when the picture was turned upside down. also covering eyes, nose and mouth slowed the performance.
Instead of changing the picture into black and white did not disrupt face recognition.
chimpanzees found bananas as fast as faces, which caused a headache for the researchers.
However, the quick recognition of the fruit was not the same as recognition of the whole picture like in face recognition.
When the pictures were changed to black and white, the bananas seem to get lost. The easy recognization of the delicacy was due to the yellow color.
Human win macaque
Surprisingly Chimpanzees spotted human faces as easy as the faces of their own species. The phenomenon is hardly explained by how the test animals had a lot of things to do with their caretakers. They poorly recognized the faces of Japanese macaque, even though this species of monkey lives in an adjacent cage. Chimpanzees react to the human babies' faces faster than to macaque`s faces, even though they have never met the babies.
Was it either about human or individual of their own species, chimpanzees recognized the faces better from the picture was taken from in front than the picture was taken from the side. This suggests that eye contact is one factor, that brings faces into chimpanzees consciousness. similar has detected on human. These results are worth taking into consideration when considering the improvement of social intelligence. Both species might capitalize the information, that comes from the faces in social life in the same way.
Tomonag a researcher in Kyoto university, institute of primate research, has estimated it in his research bulletin.
The research was published by Scientific reports
