While playing, dogs mimic their furry pals more often than they copy strangers — a behavior that could reveal more about how dogs became man’s best friend, researchers say.
Mimicking behavior may underlie what scientists call emotional contagion, a basic form of empathy where one shares others’ emotions.
In people, chimpanzees, orangutans and other primates, emotional contagion is linked to facial mimicry, a fast automatic response where they involuntarily mimic others’ expressions.
Like primates, dogs are social animals — they use their eyes, lips, teeth, heads, tails and bodies in communicative ways. As such, researchers wanted to see if dogs also experienced rapid mimicry.
