I always wondered this but never found out why? You can cough or sneeze and no one around you will do the same but as soon as you yawn, anyone else in the vicinity looking at you will also yawn. Why is that?
big_bad_buff said:Virtually any stimulus associated with yawns -- including viewing, reading about, and even thinking about, yawning -- evokes yawns. (Are you yawning yet?) Yawning spreads in a chain reaction through a group, a compelling example of human herd behavior and a reminder that we are not always in conscious control of our actions. The urge to replicate an observed yawn is clearly an automatic response triggered by our brains.
Studies partially explain the reason for yawning. Although we yawn more when sleepy or bored, it is unclear whether yawning increases alertness. And scientific evidence refutes one of the most popular myths of yawning? that it happens in response to low oxygen or high carbon dioxide levels in the blood or brain. Test subjects do not yawn more when breathing air with enhanced levels of carbon dioxide nor do they yawn less when breathing pure oxygen. One fact explains a lot of apparently inconsistent data. People yawn most during behavioral transitions, such as just after waking and shortly before bedtime. Yawning may help facilitate those changes. Contagious yawning may synchronize a group's behavior so that, for instance, a whole family goes to sleep together.

Yep. When humans were in neanderthal type stages, the dominant male in the group would yawn, everyone else in the cave would follow suit and they would go to sleep.

Shak said:Yawns Contagious to the Nicest of People...
Chicago Sun Times US "Yawns may be contagious, but they appear to be most contagious to the nicest of people--at least that's according to some new research. Researchers at Drexel University in Pennsylvania found that yawning is most contagious to people who are more empathetic. "Contagious yawning is a common but poorly understood phenomenon," wrote Steven M. Platek, the lead researcher in the study. The group showed 65 test subjects videos of people yawning and not yawning--about 24 seven-second videos--and logged their responses. They found that 42 percent of those who watched a yawner, yawned themselves. Of those, about 60 percent yawned more than once.
About 9 percent of those watching the videos yawned even when the person on the screen didn't. It seems just talking about yawning made them yawn, researchers said. Just reading this story will even cause people to yawn. Platek said the yawners who mimicked were the same kind who said "ouch" when seeing someone else in pain. They tended to be more empathetic to their fellow man. The others--those who don't yawn when people around them do--are the type who can't "feel your pain.""

Hey so a good test for a girl is to yawn and see if she yawns too. She is more likely to be empathetic if she yawns right?
Or I guess you shoudl dump her if she doesn't yawn.

That is actually a test in a bar if a girl you are checking out is secrectly checking you out too. Not exactly yawning, but she will mimic you without realizing it.
If you see a girl who's body is facing you but her face isn't, check to see if she looks at you.
If she looks again, look at your watch.
If she also looks at your watch, then she is interested.
Or drink from your glass and she will drink from hers, etc.
It is some sort of reflex or something and I never believed it until I tried in bars and it does work.
Scary that any women in bars are interested in me.
