Dogs can not only execute human language orders, but also distinguish between different human languages?indeed so

Everything in the world has spiritual things, and life is the most valuable thing on the earth.

The complicated species make this planet look colorful, and among many animals, the fetters of dogs and humans seem to be deeper. As early as the age of Ru Mao drinking blood, human beings have domesticated wolf into dogs and for their own use. Now dogs still contribute their own strength to human beings in many industries, but compared to these tools, more people will look at dogs to look at the dogs. For pets, raise at home. So why can dogs stand out among so many animals and get closer to humans? The answer to this question is composed of many factors. Today, another new factor has added the answer, that is, dogs are the only non -human animals that can distinguish different human languages. What's the meaning? Can a dog understand people? that's not what it means.

We all know that after training, we can execute human language orders, but this skill is not unique to dogs.

As long as it is trained, many animals can execute human language orders, such as pigs, cattle, sheep and other livestocks, and small animals raised by various family, and even birds. However, being able to execute human language commands is not equal to distinguishing different human languages. In fact, for most animals, they cannot even distinguish between language and non -language voices. For example, we can train a pig to fly to the food basin when hearing the word "opening rice". At the same time, we can also replace the word "opening rice" with a whistle. For pigs, There is no difference between "opening rice" and whistle. They are just a sound signal, representing a fixed instruction.

Unlike other animals, dogs can not only distinguish between language and non -language sounds, but also can even distinguish different human languages.

This is not casually talked about, but the conclusion obtained by scientists through the experimental research. At present, the research results have been published in the academic journal "Neurolmage". The chief researcher who led the research was Laura Cuaya, who raised a border shepherd named Kun-Kun. At the beginning, Laura Cuaya lived in Mexico with his dog, and Laura Cuaya always used Spanish to talk to Kun-Kun. Later, due to the change of work, Laura Cuaya moved his dog to Budapest, Hungary. Here, the surrounding neighbors speak Hungarian. Naturally, when the neighbors talk to Kun-Kun, they also speak Hungarian.

For a long time, Kun-Kun can not only obey the owner's Spanish instructions, but also respond to Hungarian, the surrounding neighbors.

So, Laura Cuaya began to think about whether his dog could distinguish between two languages, or did they only treat them as sound signals with the same meaning? In the end, in order to find the answer, Laura Cuaya set up a research team to decide to conduct a systematic research. Laura Cuaya and his research team recruited 18 different types of dogs to train them for a long time in order to keep them in a static state for a long time in the MRI scanner. After the experiment, the researchers played the reading of "Little Prince" to the dogs. The first was Spanish, then replaced with Hungarian, and finally replaced it with meaningless non -language sounds.

The final result of the experiment confirmed Laura Cuaya's conjecture. When the dog heard different languages, the brain reacted differently.

This situation is unique in the currently known animals. When other animals hear different languages ​​and non -language sounds, the brain's reaction is not different. Dogs can not only distinguish between language and non -language, but also Can distinguish different types of languages. Why is this so? Researchers believe that in the dog's brain, the processing of sounds will be divided into two layers. The primary hearing cortex is responsible for distinguishing whether the sounds hear are language, and the secondary hearing cortex is responsible for distinguishing the type of language. Studies have also found that the relationship between different languages ​​and varieties of dogs and varieties is not great, but the relationship with age is more closely.

The older the dog, the stronger the ability to distinguish between language, which may be because they have more experience in exposure to language.

It seems that the dog is indeed different compared with other animals, but don't compose the meaning of this study. This study only proves that dogs can distinguish between language and non -language sounds, and can distinguish different types of languages. It does not mean that dogs can understand human language and understand the inherent meaning contained in human language. An interesting thing is that in the process of research, the researchers also checked the brain nerve indexes of various types of dogs. The border shepherd that has always been known for its intelligence is indeed far ahead. It is not the highest among the dogs participating in the experiment. The highest brain nerve index is a multi -generation mixed dog species that cannot be determined. The brain nerve index reaches 77899.
