In fact seeing someone yawn  or hearing the word

is enough to get half  of healthy adults yawning

Yawning is an example  of emotional contagion,

Of course yawning isn't the only behavior

And when a baby in a hospital starts crying

We also copy less obvious signals  from other people

and feelings of the people in our social circle.

are actually less prone to contagious yawning,

as are children and adolescents  on the autism spectrum.

Faces tell us a lot about what others  are thinking and feeling

and people with autism tend to focus less on faces

Evidence from chimpanzees suggests that yawning

spreads when empathy exists  between two chimps.

Scientists showed chimps videos  of either familiar animals

The observers were  much more likely to yawn

We feel more empathy for people  in our social groups

contagious yawning  may help maintain relationships too.

contagious yawning is probably  a sign of good social skills.
