Studies have found that the more familiar with the dog and the person, the more right the tail shakes

On the 24th, the reporter learned from the Institute of Genetics and Development Biology of the Chinese Academy of Sciences that researchers from the institute and the cooperative unit found that they have a unique gait with everyone, and the most loyal friend of human beings -the house dogs also have a unique and unique and unique and unique and unique and unique and unique and unique and unique and unique and unique and unique and unique and unique and unique and unique and unique and uniqueness Stable tail characteristics: When interacting with unfamiliar people, the dog's tail shakes left, and when interacts with the familiar people, the tail shakes right. Related research results were published in "Cross Science" magazine.

Animal behavior is a display of brain function. Social behavior is very important for the survival of animal individuals. It not only involves interaction in species, but also involves interaction between cross -object species. "The tail of the family dog ​​is an important social behavior of interaction between dogs and dogs, dogs, and people." Zhang Yongqing, researcher at the Institute of Genetics of the Chinese Academy of Sciences.

Traditionally, researchers are mainly based on the characteristics of image collection and sports to perform artificial analysis of animal behavior. The accuracy of this artificial analysis is low and the efficiency is low. "In recent years, the computer vision field has made rapid development in gesture estimation, three -dimensional reconstruction and behavioral identification, providing new analysis methods for studying different animals and animal behaviors under different conditions." Zhang Yongqing said.

Through artificial intelligence deep learning tracking technology, the researchers found that during the three days of interaction with people, the dog's tail swing gradually shifted from the left side to the right. "This shows that the left and right side of the tail of the family dog ​​is a sensitive indicator representing the familiarity of society." Zhang Yongqing explained.

At the same time, the research team also discovered for the first time that the tail swing of the house is composed of an attractive child state with a stable swing trajectory and a transitional state of unstable transition. "These results jointly revealed that in the process of interacting with human beings, the complex characteristics and constituent laws of tail swing behavior provided a unique experimental paradigm for the study of the social behavior and potential neural mechanism of the dog." Zhang Yongqing said.
