| Video Discription | Contagious Yawning by Chimpanzees Supports Link to Empathy - Sleepy or Empathetic: What Does Yawning Mean? You know that old phrase, "monkey see, monkey do"? Well, there might be something to it, except that chimpanzees aren't monkeys. (Sadly, "ape see, ape do" just doesn't have the same ring to it.) A new paper published today in PLoS ONE has found evidence that chimpanzees have contagious yawning - that is, they can "catch" yawns from watching other chimpanzees yawning - but (and here's the interesting part) only when the chimp that they're watching is a friend. http://scienceblogs.com/thoughtfulanimal/2011/04/chimp_yawn.php - Chimpanzees' Contagious Yawning Evidence of Empathy, Not Just Sleepiness, Study Shows Contagious yawning is not just a marker of sleepiness or boredom. For chimpanzees, it may actually be a sign of a social connection between individuals. http://www.sciencedaily.com/releases/2011/04/110406192511.htm Reference Ingroup-Outgroup Bias in Contagious Yawning by Chimpanzees Supports Link to Empathy PLoS ONE, 6 (4) : 10.1371/journal.pone.0018283 http://www.plosone.org/article/info%3Adoi%2F10.1371%2Fjournal.pone.0018283 Abstract Humans favor others seen as similar to themselves (ingroup) over people seen as different (outgroup), even without explicitly stated bias. Ingroup-outgroup bias extends to involuntary responses, such as empathy for pain. However, empathy biases have not been tested in our close primate relatives. Contagious yawning has been theoretically and empirically linked to empathy. If empathy underlies contagious yawning, we predict that subjects should show an ingroup-outgroup bias by yawning more in response to watching ingroup members yawn than outgroup. Twenty-three chimpanzees (Pan troglodytes) from two separate groups watched videos of familiar and unfamiliar individuals yawning or at rest (control). The chimpanzees yawned more when watching the familiar yawns than the familiar control or the unfamiliar yawns, demonstrating an ingroup-outgroup bias in contagious yawning. These results provide further empirical support that contagious yawning is a measure of empathy, which may be useful for evolutionary biology and mental health. - Video: Campbell & de Waal (2011) - Chimpanzee Contagious Yawning Tara, an adult female, yawns while watching a video of another chimp from her social group yawning on the iPod touch.
