I think yawning is caused by a subconscious reflex somewhat related to the amount of oxygen, and when you see someone yawn, it reminds you to check your own level of oxygen by yawning.
I pulled that one from 'you know where'...

yawns are the result of a high concentration of carbon dioxide (which is built up in the lungs when you are tired, hence the yawn), and so if a room has high CO2 concentration, a lot of people will start yawning, and it will appear that it is contagious....or not - i'm guessing here
where are our science experts when you need them???

I would guess that it is a psychosomatic reaction.
Because yawning is a response to shortage of oxygen, the sight of someone else yawning might trigger, by way of association, an automatic shift of attention to the present state of oxygen (surely too brief to be consciously available in most circumstances).
A system that is exogenous to the breathing module might have no idea about the level of oxygen that requires correction by inhaling or exhaling. Thus, attention to the state of oxygen may lead the perceiver himself to yawn, which might hamper the balance between oxygen and CO2.
Just a thought anyway.
