A person yawned, and the people around him followed him to yawn. Why is yawning "contagious"? Psychologist at Drexel University in the United States
Steven Praczech believes that the so-called yawning infection is more likely to be among those who like to imagine themselves as others.
occur.
To test this view, Pura Czech and his colleagues at SUNY had volunteers watch a video of people yawning. There are 4 results
More than 0% of volunteers yawn with the people on the screen, and 60% of these "infected" people have more than one
owe. The researchers immediately asked these people to undergo a transference ability test, and their scores were very high.
Praczech said these people are the kind of people who also shout "Ouch" when others step on sharp things. This result explains why psychopaths
It is rarely contagious by others' yawning because it is difficult for them to engage in empathy activities. This is one aspect, and there is another saying, "Why are there 100,000 Whys"
On
There are three theories that yawning is contagious. These three theories are: physiological theory, boredom theory, and evolutionary theory.
Physiological theory believes that yawning is a reaction in which the brain realizes the need for oxygen supplementation. Yawning is contagious because it is in a room
Everyone in the room may feel that they need oxygen at the same time. Yawning may also be stimulated by external factors, which is largely the same
I feel hungry when I see others eating.
The assumption that the theory of boredom is that if everyone finds something boring, they will yawn. But this theory cannot be explained
Why do people yawn when they feel bored? Unless they use yawn as an instinctive way to express displeasure about something in physical language
interest.
Evolutionary theory believes that people yawn to expose their teeth, and this behavior was passed down by our primitive ancestors. Yawning may be sending someone else
A kind of act of issuing a warning. Given that human development has entered a civilized society, it is outdated to warn others by yawning.
Since people have not found the exact reason why yawning is contagious, this question remains a mystery.
Some people also say that yawning is because the body feels tired and needs oxygen, so they directly inhale a large amount of air from their mouth and nose to obtain oxygen.
Qi replenishes. As for why you want to yawn when you see others yawn, there is a saying that it is said that it is a subconscious survival competition of human beings.
Compete for instinct, because when someone starts yawning in a place, it may imply to people that the air (oxygen) in this place is almost insufficient, based on survival
Instinct, humans subconsciously remind themselves to take a large mouthful of air as soon as possible, so as not to be unable to breathe when the air is insufficient (oxygen)
Fresh air, because survival is an instinct and a subconscious reaction, so even if you see pictures, you will have a reaction (just like a boy who sees a newspaper
The cool pictures of Zhang Magazine also have physiological reactions, brain stimulation suggests, and things are fake and real—————————————————————————————

It has a more general meaning, that is, changes in the body's condition. Studies show that when people are tired, wake up, or otherwise alert
When the state changes, it will yawn.
The characteristic of yawning is that your mouth opens and takes a deep breath, while your chin and the muscles in your body also stretch out. Many animals will be beaten
It is owed, and this action involves the interaction between the unconscious brain and the body.
For many years, people thought that when tissues around the lungs detect that the oxygen concentration in the lungs becomes lower, people will yawn to inhale more air. But I
We now know that the lungs may not necessarily detect insufficient oxygen. Moreover, although the fetus' lungs cannot breathe, the fetus will be treated
Yawned. In addition, breathing and yawning movements are controlled by different brain regions; when the oxygen concentration of the paraventricular nucleus located in the inferior optic mound of the brain becomes lower,
It will make people yawn. Another hypothesis is that yawning comes from people's fatigue and boredom. But this may also be wrong.
In addition to other functions, the paraventricular nucleus of the inferior optic mosaic seems to be the "yawning center" of the brain. Paracavity nuclei contain certain chemistry that can cause yawning
Message molecules, including dopamine, glycine, oxytocin and corticotropin. Take corticotropin as an example, it will wake up at night and
It is secreted in large quantities, causing people to yawn and stretch their muscles. Yawning also seems to require nitric oxide made by specific nerve cells in the paraventricular nucleus. These
When cells are stimulated, they will activate the brainstem and (or) hippocampus cells, causing yawning. Yawning seems to have a rewarding element too: if
If you resist yawning, the whole yawning process will be less satisfying.
The claim that yawning is contagious is correct. Just seeing, hearing or thinking of yawning can make people yawn, but we are
Very little is known about the reasons; over the years there have been many theories that want to explain this phenomenon. There is evidence that yawning is an animal in the environment or body
When conditions change, one way to communicate these messages to other animals may be to coordinate the behavior of animals with each other. If so
Then the human yawning behavior is most likely an evolutionary remains that has lost its meaning of existence.
