Dogs know emotions according to facial expression and voice intonation

Dogs, based on facial expression and voice intonation, recognize our mood, which is characteristic that so far they have described exclusively to humans

Animals are able to recognize the emotions of other animals and understand their intentions, but only within one and the same species. To understand the feelings of another kind, the brain must be able to turn images and sounds that are perceived in mental appearance. He must be able to evaluate, compare, connect and combine them.

For research needs, scientists from the British University Lincoln and Brazil University in São Paulo have placed 17 dogs in front of photos of smiling people, combining them with the sound of cheerful, angry voices.

Dogs have successfully tied the happy voice to the picture of the happy person, as well as the angry voice to the person's face, indicating that dogs are capable of analyzing the link between the two emotions and proving the links of information.

However, researchers point out that there is a significant difference between the taught reaction, the grieving voice, and the different data gap, writes the journal Biology Letters, records the Telegraph.

“Our study shows that dogs are able to connect two types of sensitive information and to achieve a consistent perception of human emotions. This cognitive ability has so far been observed only in people”, Kun Guo of Lincoln University said.

Many dog owners testify that their pets are highly sensitive to the humor of family members.

However, researchers point out that there is a significant difference between a learned reaction, such as an angry voice, and the knowledge of different data.

In this research, dogs have not been given an opportunity to get acquainted with the subjects shown in the photograph and their voices. This leads to the conclusion that the ability to combine emotional signs of dogs is born”, says Daniel Mills.

This is probably the result of special relationships that dogs have with people”, states for AFP Research Director Natalia Albique.
