Dogs also know how to classify photos

Dogs can arrange photos according to different genres, similar to the way people and other primates still do, scientists have revealed.

Friederike Range at the University in Vienna (Austria) and his colleagues trained 4 dogs to differentiate the pictures with dogs with no pictures.

First, these animals are viewed simultaneously with a landscape image and a dog image, and will be rewarded if they choose the following photo, by touching a computer screen with their feet. After the training was quite proficient, the experimental animals were shown a new landscape picture and photos of the dogs. They continue to point out exactly the pictures of their fellow people.

In the final stages of the experiment, the animals will see a strange dog placed on a landscape image familiar to them. As a result, they still recognize that this dog is compared to the picture only.

Range argues that this is evidence that dogs are capable of reasoning."We know that dogs can distinguish" food "or" enemy "from experience, but this is the first time we teach them an abstract concept -" a dog "- and notice them. can turn this concept into a new situation ".
