There is already quite a lot of research
evidence showing that the way we communicate to dogs is different from
the way we communicate to other humans. When we talk to dogs, we use what is called “dog directed speech”.
This means we change the structure of our sentences, shortening and
simplifying them. We also tend to speak with a higher pitch in our
voices. We also do this when we are not sure we are understood or when
talking to very young infants.
A
new study has shown we use an even higher pitch when talking to
puppies, and that this tactic really does help the animals to pay
attention more. The research, published in the journal Proceedings of the Royal Society B,
showed that talking to puppies using dog-directed speech makes them
react and attend more to their human instructor than regular speech.
To
test this, the researchers use so-called “play back” experiments. They
made recordings of humans repeating the phrase “Hi! Hello cutie! Who’s a
good boy? Come here! Good boy! Yes! Come here sweetie pie! What a good
boy!”. Each time, the speaker was asked to look at photos of either
puppies, adult dogs, old dogs or at no photos. Analysing the recordings
showed the volunteers did change how they spoke to different aged dogs.
The
researchers then played the recordings back to several puppies and
adult dogs and recorded the animals’ behaviour in response. They found
the puppies responded more strongly to the recordings made while the
speakers looked at pictures of dogs (the dog-directed speech).
The study didn’t find the same effect applied for adult dogs. But other studies that recorded dogs’ reactions to the human voice in live interactions, including work I have done, have suggested dog-directed speech can be useful for communicating with canines of any age.
Following the point
It’s
also been proven (and most dog-owners will tell you) that we can
communicate with dogs through physical gestures. From puppy age on, dogs
respond to human gestures, such as pointing, in ways other species can
not. The test is very simple.
Place two identical cups covering small pieces of food in front of your
dog, making sure it cannot see the food and doesn’t have any
information about the contents of the cups. Now point to one of the two
cups while establishing eye contact with your dog. Your dog will follow
your gesture to the cup you pointed to and explore the cup, expecting to
find something underneath.
This is because your dog understands
that your action is an attempt to communicate. This is fascinating
because not even human’s closest living relatives, chimpanzees, seem to
understand that humans communicate intent in this situation. Nor do wolves – dog’s closest living relatives – even if they are raised like dogs in a human environment.
[how to teach dogs to follow a finger point]
This has led to the idea that dogs’ skills and behaviours in this area are actually adaptations to the human environment.
That means living in close contact with humans for over 30,000 years
has led dogs to evolve communication skills that are effectively equal
to those of human children.
But there are significant differences
in how dogs understand our communication and how children do. The theory
is that dogs, unlike children, view human pointing as some kind of mild command,
telling them where to go, rather than a way of transferring
information. When you point for a child, on the other hand, they will
think you are informing them about something.
This ability of dogs
to recognise “spatial directives” would be the perfect adaptation to
life with humans. For example, dogs have been used for thousands of
years as a kind of “social tool” to help with herding and hunting, when
they had to be guided over a great distance by gestural instructions.
The latest research affirms the idea that not only have dogs developed
an ability to recognise gestures but also a special sensitivity to the
human voice that helps them identify when they need to respond to what’s
being said.
