Dogs hear our words and how we say

Many times it seems that man's best friend perfectly understands everything we say you; the truth is that the brain of dogs differentiates itself both the sounds of human speech and the way we express ourselves: with joy, anger, sadly ... This is, dogs do not only listen to what we say, but also how we say it.

This is the conclusion of the last work of a team of researchers from the University of Sussex (UK) who performed a series of experiments with dogs to delve deeper into the connection between human speech and its reception by the dogs. Thus, "we do not know how dogs understand speech, yes we have seen that show opposed to verbal content and information related to the speaker brain trends," says the agency Sync Victoria Ratcliffe, who led the study.

In their experiment, which involved 25 dogs, experts installed two digital speakers to five feet on each side of the dogs so that, by releasing the sound, this entered simultaneously in each ear. Different signals, some with more emphasis on content and other verbal intonation were sent. Listening family orders rather obvious to them meaning, dogs turned their heads to the right showing activity in the left hemisphere of the brain. When they heard the orders with an exaggerated intonation, dogs showed more activity in the right hemisphere.

"This implies that process speech components separately, and suggests that the left hemisphere of the brain is more active to process aural or verbal information of speech and the right hemisphere is more active in processing information related to the speaker signal" Ratcliffe explains.

This is the first time that a scientific study shows that dogs are also able to differentiate and process the different components of human speech in a very similar way as we do. According to the study, published in the journal Current Biology, the perception of speech in humans might have developed during domestication and could also be a feature shared by other mammals such as horses.
