Dogs can sense human emotion through canines
Dog is the best friend of man.
Scientists have shown for the first time that the animals are masters at getting emotions, mood and their ability to read not only applies to other canines - it also extends to humans.
The insight, from scientists at the University of Lincoln, which breed only creatures with the ability of people to "tune in" a different species.
Vet Professor Daniel Mills, who led the study, sitting 17 pet dog in front of a screen and jump up two images of the face of a dog - one that it looked cheerful and one of That appeared angry.
He also played a tape of dogs barking and saw one of the two images of animals were drawn.
He found that when the barking sounded happy and excited, the dogs spent longer looking at happy faces.
But when they heard growling, they focus on her angry face.
However, if the barking is not gentle and non-threatening, they spent the same amount of time to look at each picture.
This, according to Professor Mills, indicating that they have incorporated what they can see and hear in order to assess the mood of the dog in the picture.
Pictures show the people, together with the speech band, produced a similar result, though the animals were less interested in the human face.
Dogs have proven to be able to speak with happy faces from the previous sad.
But it is not clear if they are simply trained to give the two apart without understanding what they are seeing.
The use of animal studies did not see a dog or a person in the image before and had not received any training on the job.
Prof. Mills said: "This is a long debate whether dogs can recognize human emotions.
'Many dog owners report anecdotally that their pet seems very sensitive to the mood of the members of the human family.
"However, there is an important difference between learning to respond appropriately to an angry voice, and realized a series of very different signs that come together to address the sensory stimulation contact in one.
"Our discovery is the first to show that dogs really recognize these emotions in humans and other dogs. '
Dr Kun Guo colleagues, a psychologist, said: "Previous studies have shown that dogs can distinguish between the emotions of people from the signs such as facial expressions, but this is not the same as identifying emotions.
"Research shows us that dogs have the ability to integrate two different sources of information in a cognitive sense of emotional unity in both humans and dogs.
The team has previously shown that dogs use the same trick as people when looking at human faces.
Called 'left gaze bias', it involves focusing on the more expressive right-hand side of the face.
Dogs also exhibit contagious yawning, starting to yawn when their master does – something that is thought to be a sign of empathy.
