Chimpanzees' contagious yawning evidence of empathy, not just sleepiness, study shows
Date:4/6/2011

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.

New research at the Yerkes National Primate Research Center, Emory University, may help scientists understand empathy, the mechanism thought to underlie contagious yawning, in both chimpanzees and humans. The research also may help show how social biases strengthen or weaken empathy.

Scientists at Yerkes discovered chimpanzees yawn more after watching familiar chimpanzees yawn than after watching strangers yawn. The Public Library of Science One (PLoS ONE) is publishing the study online on Wednesday, April 6, 2011.

Yerkes researchers Matthew Campbell, PhD, and Frans de Waal, PhD, propose that when yawning spreads between chimpanzees, it reflects an underlying empathy between them.

"The idea is that yawns are contagious for the same reason that smiles, frowns and other facial expressions are contagious," they write. "Our results support the idea that contagious yawning can be used as a measure of empathy, because the biases we observed were similar to empathy biases previously seen in humans."

Campbell is a FIRST postdoctoral fellow at Yerkes and Emory (Fellowship in Research and Science Teaching). De Waal is director of the Living Links Center at Yerkes and C.H. Candler Professor of Psychology at Emory.

They studied 23 adult chimpanzees that were housed in two separate groups. The chimpanzees viewed several nine-second video clips of other chimpanzees, in both groups, either yawning or doing something else. They yawned 50 percent more frequently in response to seeing members of their group yawn compared to seeing others yawn.

In humans, scientists have identified certain parts of the brain that are activated both when someone experiences pain and when they see someone else experiencing pain. In these experiments, people tend to show m
