简介：
Yawns Are Contagious When You're with Friends
哈欠在熟人之间更容易“传染”?
Research with chimpanzees finds that chimps yawn more around other yawning chimps from their own community than with those from a separate community. Christie Nicholson reports
黑猩猩研究“哈欠传染”现象的研究人员发现，与碰到“陌生人”时相比，当黑猩猩碰上“熟人”在打哈欠，它们会被“传染”上更多的哈欠。

[Yawn sound.] Oh sorry. Well, now that I’ve yawned, you might be yawning, too. Right?
[哈欠声]噢，不好意思,我刚打了个哈欠，你是不是也在打啊？
Studies have linked contagious yawning in humans to our capacity for empathy. In fact, scientists have found that those who exhibit empathy easily and often also do more yawning because someone else yawned.
研究指出，人类的哈欠传染现象与我们的移情能力有关。事实上，科学家已经发现，容易且经常移情的人，会因为其他人打哈欠而更频繁地打哈欠。
If contagious yawning is indeed a sign of empathy, then we should probably do it more with friends and acquaintances. Because we have an empathetic connection with them that we don’t have with strangers. An Emory University research team decided to test that idea—with chimpanzees, who also yawn contagiously.
如果说，带有感染力的哈欠确实是“移情”带来的效应，那么，我们跟朋友、熟人在一起的时候，就理应染上更多的哈欠。这是因为，我们和熟人之间存在我们与陌生人之间没有的移情“纽带”。埃默里大学（Emory University）的一支研究团队，决定用同样能“传染”哈欠的黑猩猩来验证这一想法。
Researchers Matthew Campbell and renowned primatologist Franz de Waal, studied 23 chimpanzees who live in two separate groups. Each chimp watched 20 minutes of videos of others chimp either yawning or just resting. Chimps who saw yawning chimps from their own group yawned 50 percent more than when they watched yawning chimps from the stranger group. The research is published in the journal "Public Library of Science One".
研究者马修•坎贝尔（Matthew Campbell）和著名灵长类动物学家弗兰兹•瓦尔（Franz de Waal）将23只黑猩猩分成相互隔离的两组。他们为每一只猩猩放映了20分钟的录像，录像里是其他正在打哈欠或者休息的黑猩猩。结果发现，如果一只黑猩猩看到录像里打哈欠的猩猩与自己同组，那么它将平均多打50%的哈欠。这一研究已发表在《公共科学图书馆•综合》上。
Interestingly, chimps paid more attention to the videos of unfamiliar chimps. Because unfamiliarity breeds concentration. Whereas familiarity apparently breeds [Yawn sound.]
有趣的是，猩猩们在观看另一组猩猩的录像时更为专注。因为陌生会引起兴趣，而熟悉会引起……（哈欠）
