Dogs know face recognition

Research by Finnish scientists shows that dogs have the ability to recognize faces familiar to them when looking at photographs.

During the study, scientists at the University of Helsinki examined the ability of the dog to recognize faces by tracking them for many consecutive images on a screen.

According to Nature World News, among these pictures are pictures of the owner, strangers, dogs in a family and children they have never seen before.

The team said, when looking at photos of the same type, these dogs stopped looking at the screen longer. With familiar faces, they also spend more time observing than unfamiliar images or they rarely see before.

By analyzing the behavior of dogs looking at images of these faces, the researchers determined that dogs not only recognize the natural properties of the face, but also recognize the information displayed on the face. image and meaning of that image.

Previous studies have shown the role of the face in this human-to-animal communication. However, this is the first study to investigate the ability to identify faces in dogs through tracking eye movements.

Facial recognition is often considered to exist only in humans and possibly in some primates. Therefore, the results of this study marked a new step in research in animals close to humans.
