yawning is contagious only if someone sees you do it ... as a sort of social action.
It is not contagious in the disease sense.
The physiologic function of yawning is to relieve the imbalance between where the blood flows in the lungs (mainly at the base) and where the air flows (mainly at the apex). Note that this is a problem mostly when you are in an upright posture.
Yawning is contagious, at least to humans. Many animals yawn, but only dogs, chimps, and humans are known to yawn after someone else does. There is no conclusive evidence why we yawn to begin with, but it's possible that contagious yawning may have something to do with social bonding and empathy. For example, autistic people tend not to yawn after another person does, and children under the age of four don't do it either. This suggests that yawning after someone else is a sympathetic and social act, similar to unconscious mimicking.
When tired, yawning is psychologically "contagious", but not physically contagious in the most common sense of the word.
