Contagious yawning, why we share, and Bernie Madoff

Laura Fitzpatrick in Time:

Gordon Gekko got it wrong. In his new book The Age of Empathy: Nature's Lessons for a Kinder Society, primatologist Frans de Waal uses a variety of studies on empathy in animals to debunk the idea that humans are competitive to the core. He talked to TIME about contagious yawning, why we share and Bernie Madoff.

How do you define empathy?

Empathy is sometimes defined by psychologists as some sort of high-level cognitive feat where you imagine how somebody else feels or how you would feel in their situation. But my definition is more focused on the whole of empathy, and that includes emotions. If you are sad and crying, it's not just that I try to imagine how you feel. But I feel for you and I feel with you.

You explain in the book that empathy really starts with our bodies: running together, laughing together, yawning together. So yawning really is contagious?

Yeah. Dogs catch yawns from their owners. Chimpanzees yawn [in response to those] that we show them. Yawn contagion is very interesting because it's a very deep bodily connection between humans or between animals. Humans who have problems with empathy, such as autistic children, don't have yawn contagion.
