New research provides evidence that dogs understand what is said, not just the intonation of the owner, in responding to commands.
Dogs are able to respond to various commands made by their owners, but these often wonder if they understand what is said or just intonation or any "hint" of what was spoken, responding automatically. A survey published on Wednesday offers the first answers to this question and indicates that man's best friend is able to process the most sophisticated form of human speech than imagined.
The study, published in the journal Current Biology, provides evidence that dogs are able to understand both subjective components of speech, such as intonation and emotional content, as the words themselves.
"While we can not say how much or how do dogs understand information from human speech, we can say that dogs respond well to verbal information as elements related to the person talking and these components seem to be processed in different regions of their brains "says Victoria Ratcliffe, of the School of Psychology at the University of Sussex, England, and an author of the study.
The survey also showed that dogs process human speech in one hemisphere of the brain, and additional information on the other. Previous studies have shown this trend when they process sound information issued by other dogs.
