向六只成年雌性黑猩猩播放了黑猩猩反复打哈欠的视频场景，或者黑猩猩张开嘴巴的面部表情而不是打哈欠的视频。六只雌性黑猩猩中有两只对哈欠视频表现出明显更高的打哈欠频率；没有黑猩猩表现出相反的情况。陪伴母亲的三只幼年黑猩猩根本没有打哈欠。这些数据让人高度联想到有关人类打哈欠的传染性影响。传染性哈欠被认为是基于同理心的能力。黑猩猩的传染性哈欠提供了进一步的证据，表明这些类人猿可能具有高级的自我意识和移情能力。
Six adult female chimpanzees were shown video scenes of chimpanzees repeatedly yawning or of chimpanzees showing open-mouth facial expressions that were not yawns. Two out of the six females showed significantly higher frequencies of yawning in response to yawn videos; no chimpanzees showed the inverse. Three infant chimpanzees that accompanied their mothers did not yawn at all. These data are highly reminiscent of the contagious yawning effects reported for humans. Contagious yawning is thought to be based on the capacity for empathy. Contagious yawning in chimpanzees provides further evidence that these apes may possess advanced self-awareness and empathic abilities.
