We don't know why it is contagious, but they say one of the mental reasons we yawn is because our mood is changing.
its like a chain once some1 starts it triggers summin in your head to do the same its like if you cough sumtimes straight after u have an impulse to cough
yeah
This isn't a direct answer (there isn't really one), but an interesting idea from The Straight Dope [excerpt]:
<<<
... observe that whatever yawn-inducing conditions prevail for you also apply to your friends.
If you're out late in some crowded dive, you're probably all tired, all warm under the collar, and all breathing the same stale air. You're probably all on the verge of a yawn, too, and the power of suggestion from seeing one person do it is enough to push everybody else over the edge.
Adults rarely catch a case of the yawns from a child or animal, which tends to corroborate this idea.
Children usually have different sleep schedules and respiration rates from adults, so you would expect them to yawn at different times.

I think so. Reading this question made me yawn. :(
many years ago i saw something about this on t.v. and they said that one of the reasons we yawn when we see other's yawn is because it is a form of bonding (kind of like, if someone you don't know smiles when they walk past you, you smile back). i don't know if i buy it, but that's what 'experts' said....
