From Carlos Tellez:

Re: Why is yawning contagious? (March 21, 2008): I am originally from Colombia, South America. Yawning in Colombia is usually associated with being tired or with being hungry. Could it be that yawning could unconsciously be associated with different feelings? Perhaps yawning is not only caused by a lack of oxygen but could it also be caused by a culturally learned response?
