Baby talk may make grown-ups sound ridiculous to many people, but that doesn’t take away from its value. Extensive research has shown that human infants are better able to learn language when we talk to them using higher pitches and at a slower speed than when we talk to other adults. This style of communication is called “infant-directed speech”, and it’s natural for many folks to slip into it when addressing young individuals, especially those who are not yet verbal.
A new study called “Dog-directed speech: why do we use it and do dogs pay attention to it?” suggests that the same principle may be operating when humans speak to dogs—another of our social partners who don’t fully understand our language. People tend to talk to their dogs in a way that is similar to the way they address children. There may be value in this “dog-directed speech” as well.
This study investigated the behavior of two species, and reported a major finding about each of them. On the human side, only women were studied, and researchers found that they used dog-directed speech with dogs of all ages, but used higher pitches when they were talking to puppies than when addressing fully grown dogs. For the canines, this worked out well based on their age-related responses to the way we talk to them. Adult dogs were equally responsive to normal speech and dogs-directed speech. Puppies, however, became more engaged when addressed with dog-directed speech than when the women spoke to them as they normally talk. Specifically, it was the higher pitch in the dog-directed speech that influenced how attentive puppies were.
There are many questions that flow naturally from this study and its intriguing results. Do men talk to their dogs with higher-pitched, slower speech patterns, and does the age of the dog influence the degree to which they do it? Do dogs who look more juvenile because of larger eyes, shorter muzzles and bigger heads elicit dog-directed speech more than dogs who have a more mature look? Does dog-directed speech facilitate language learning in dogs as it does in human babies?
Do you talk to your dog using a different speaking style than the one you use for adult humans?
