Kirsten Rewey asks: >Is yawning part of a reflex? If so, can it be initiated by oxygen levels in >the bloodstream? Many questions about yawning can be found in the following article: Baenninger, R. (1 997). On yawning and its functions. _Psychonomic Bulletin & Review_, _4_, 198-207. I would summarize it for you and answer your questions specifically, but it has been two years since I read it, and I have to get going.
