- The first scientific theory explaining why we yawn is the behavioral synchronization hypothesis. According to this theory, contagious yawning functions to synchronize or coordinate group behavior between species.
- Ethological studies have shown that yawning clusters within a group before a collective transition to a different behavior. This suggests that contagious yawning helps coordinate group behavior among species.
- A study on wild African lions found that contagious yawning led to synchronized body movements and facilitated group behavior transition.
- Yawning can be likened to an orchestral conductor of movement in animals. (Time 0:00:00)
La teoría de la sincronización conductual del bostezo Transcript: Speaker 1 The next theory is a little bit more wacky. It’s called the behavioral synchronization hypothesis of yawning. Let’s just call it the behavioral synchronization theory. It poses that contagious yawning functions to synchronize or coordinate group behavior between group species. And in fact, ethiological studies of wild animals have shown that natural clustering of yawning within a group occurs right before a collective group of animals transitions to a different Behavior. And it’s statistically reliable. And there was a fascinating study maybe two years ago. And it was a study by cassette and colleagues and they tracked wild African lions. And what they found was that the collective body movements of the lions all synchronized more as a group after a contagious yawn. So for example, when that pride of lions transitioned from moving to resting or vice versa, it was preceded commonly by a synchronized yawn, a yawn that one instigated, which then spread Contagion like to facilitate the group behavior en masse. So it’s almost as though yawning is acting like an orchestral conductor of movement. (Time 0:15:03)
