The temporal proximity of yawning to bed and waking times and other occasions of low arousal is probably the basis for yawning as a paralinguistic al for drowsiness. Yawning is also therapeutic in preventing postoperative respiratory complications Cahill, and in adjusting the air pressure rroom the middle ear Laskiewicz, There is much popular opinion but little empirical evidence about the physiological cause and function of yawning.

The present studies evaluated the effect of elevated levels of CO2, 02, and exercise on human yawning. These interventions alter blood levels of these gases and breathing rates Comme, The effects of breathing gases with subnormal levels of O2 were not investigated because of concern about stressing the subjects. Method : Subjects. The 18 subjects 3 males, 15 females were 17 to 21 year old college freshmen who volunteered to earn experiment participation credit for an introductory psychology class.

There is much popular opinion but little empirical evidence about the physiological cause and function of yawning. Also, yawns were self-reported because attempts too bserve subjects directly may reduce yawning frequency because of the social sanctions against public yawning; several subject participating in a chatt study volunteered the comment that they did p2 like to y awn while being watched. Yawn duration was measured manually from the event recorder records with a millimeter rule. These interventions alter blood levels of these gases and breathing rates Comme, The difference in the temporal chat of yawning and stretching and the ability to perform elther behavior autonomously suggests that yawning is not simply the facial component of a generalized stretch response.

Provine, An evaluation of univariate chta indicated that the of yawns produced in the hcat condition was Women wanting sex Uniondale different from the average in cha two baseline conditions.
