【科普】狗也会被人的“哈欠”传染

Observing others' yawning make us yawn. This phenomenon, which is called contagious yawning, has previously been reported only in humans and in other primates such as chimpanzees, and is thought to relate to the capacity for empathy.

The current study is the first to report that human yawns induce yawning in dogs.

Such a contagiousness of yawning between humans and dogs may help coordinate interactions as well as communication between humans and dogs.
