Is yawning is contagious?

I've read somewhere that yes, it is contagious, if you are aware that he is yawning. Like your officemate or someone whose table is near yours on a restaurant. If your aware of his presence like if your observing him and he yawns, there is a chance you will yawn as well. If a lot of people yawned after he did, then you're not the only one who is observing him.;)

Yes, I think it is cause it happens to me all the time too. I keep yawning now just because of reading about it even! I've always wondered what the reason is behind it though. I guess it's just a psychological thing or something!

I think to some extend it’s true to say that yawning is contagious. I consider it to be a psychological influence on others as the people who are yawning are in the same physical situation eg they are equally tedious and tired etc.

I think yawing is pretty much only psychological. If you see someone yawing, try not to breathe in what he/she is giving out. most of it is carbon dioxide and bacterias. Good luck!

I also think that yawning is contageous, even though there are no scientific explanations (as far as i know) on why a person yawns when he saw another person yawned. Þ
