How Is Yawning Contagious – What is yawning? And why do we do so much? Neuroscientist and zawn expert Robert Provine says “it’s ancient and independent.” It comes from early evolution and is common to many creatures—even fish. It is independent in the sense that it originates in the brain, below the lower level of the brain, where other responses are embedded and can no longer qualify as thoughts.
Yawning can be caused by many things, including fatigue, sleep, and heat. A 2014 study found that there is a “warm window” (around 68°F) for yawning; As the ambient temperature approaches body temperature or drops close to freezing, we yawn a little. According to the newspaper, we can yawn to regulate our brain temperature. This is not the same as saying that we yawn to take in extra air, as evidence to date suggests that we do not. It means that yawning can draw cooling air into the brain through the nose and mouth.
How Is Yawning Contagious
Over the years, scientists have observed “contagious yawning” in primates, humans, chimpanzees, bonobos, wolves, and dogs. Yawning sounds good, so why not join in when someone yawns? Well, you’re not “joining in”, because you’re not taking the yawn on any conscious level. It happens because you can’t control yourself. If you become self-conscious about yawning, it will stop.
Evolutionary Biologist Suggests Yawning May Be A Means For Telling Others To Be More Alert
, argues that yawning may not be contagious—or that we’re not sure yet. Psychologist Rohan Kapitány from the University of Oxford reviewed the scientific literature on contagious yawning and found little evidence to support our long-held belief that yawning is contagious.
“The belief that yawning is contagious seems obvious,” Kapitány told PsyPost, “but there are some big reasons why we do it.
Mistake in this. If we fail to distinguish between what we think we know, we can have assumptions that do not reflect reality. At this time, the writings were not suspicious of contagious yawning, and ended with many unofficial and final procedures.”
However, because Kapitány’s research was small and limited, he and his co-authors encourage other scientists to challenge their own research findings.
Why Is Yawning Contagious?
“I could be wrong!” Kapitány said. “Maybe yawning is contagious!” Kapitány says he would like to see “stronger” experiments to pretend that yawning is contagious rather than just showing it over and over again [in] slightly different places with richer and clearer explanations.
Some people with autism or schizophrenia do not show a contagious response. The same is true for children under the age of four. This has led to different theories about the relationship between yawning and empathy and the mirror-neuron system (MNS) in the brain. The hypothesis here is that a decrease in the MNS may lead to missed sympathetic signals leading to contagious yawning. The MNS seems to be taking part in the process. fMRI studies on several people have shown that certain parts of the brain “light up” in response to images of yawning, perhaps even more than they do with empathy.
Parts of the amygdala – a part of the brain associated with fear and intense attention – light up in response to images of yawning. Sometimes we yawn when we are nervous, like before we start a game.
So, maybe we yawn during those times to prepare our brain for “fight or flight.” Perhaps contagious yawning is an evolutionary shortcut for programming the brains of an entire group of hominins to react quickly in response to a threat. (If that were the case, then some of the older members would be left out, because older people are less susceptible to yawning.) We are social mammals; the evolutionary reformation of a preexisting condition (purposive yawning into contagious yawning) would help groups survive.

Or maybe it’s much deeper than that. Laughter also feels good, and it can be contagious. Like laughter, contagious yawning can help groups bond—by showing sleeplessness, and relaxation. It probably has more to do with feeling safe than feeling threatened.
Contagious yawning is still a scientific mystery. We tend to think about it and try to stay grounded
The reason. But why does the state of evolution have to have one real reason for it? Often times, cultures survive because they cover multiple bases. Sometimes, they’re just mutants whose original purpose has faded, but because they don’t work against the creature’s survival, there’s no pressure to get rid of them.
Another modern form of yawning is less contagious—false yawning. You can do this as a low-key way to show that the conversation has taken a long time. Why not take part in a science experiment the next time you meet your boss? Lean back in your chair and yawn, then see if he yawns again. Maybe there are some scientific discoveries in there… but maybe no pay raises.
Contagious Yawning Is Linked To Age, Scientists Find
Have a Big Question you want us to answer? If so, let us know by emailing us. It took scientists six months to train Alexandra the red-legged turtle, but by the summer of 2009 she had learned to fake yawning. An official attempt came later. Once a day for several weeks, the research team placed Alexandra on one side of a small tank with another turtle—either Mose, Aldous, Wilhemina, Quinn, Esme, or Molly—next to her. Then he told him to turn his head back and drop his jaw, as he had been taught, and look at the other turtle. Would Moses have dropped his jaw? Is it Aldous or Wilhemina? Was there any indication that Alexandra’s tortoise could be contagious?
There was none. The research team tried again, this time Alexandra faked her yawn not just once but two or three times; however, the watching turtles did not respond. The scientists then had Moses and his colleagues watch a video showing Alexandra in the middle of a natural yawn, not the fake one she had been doing for months. Again, the yawning was not contagious.
“It is possible that actual yawning is necessary to motivate the turtle,” the authors concluded in their 2011 paper, which was published in the journal Nature.
. But “our findings strongly support the idea that turtles do not yawn in a contagious way.”

This access, or lack thereof, can be seen as restrictive. But based on what we know about recurring problems in science, the paper turtle could be a sign of things to come. Could it be that the rest of the body of research into contagious yawning—a small but fascinating field that began 30 years ago—is resting on its laurels?
In the 1980s, when yawning began to be studied in the lab, scientists thought that the results would be unique to humans. Not that the yawning was unusual; Indeed, this behavior has been observed not only in animals, but also in birds, reptiles, and celestial bodies. In fact, contagious yawning, caused by another, appears to be a unique, social change—a form of empathy, perhaps—if not a sign of higher consciousness. “Although yawning research is in its infancy,” wrote psychologist Robert Provine, the grandfather of contagious yawning research, in 1989, “its future looks bright.”
Provine was the first to show, in the 1980s, that a videotaped yawn is more likely to yawn than a videotaped smile. But the work did not begin until 2003, when Steven Platek, a researcher in Gordon Gallup’s lab at the State University of New York at Albany, provided evidence that contagious yawning may be related to “theory of mind”—a person’s ability to think about another person. someone else’s opinion. Papers published after Platek showed that both children with autism and adults with psychopathic tendencies were less likely to imitate one’s yawn than others. Meanwhile, a group of researchers found evidence of contagious yawning—and thus perhaps a form of consciousness—in primates, domesticated dogs, parakeets, rats, and possibly even wolves and monkeys.
It didn’t take long for Provine to prove that yawning can spread. But the study of contagious yawning has evolved so much since then, and has spread so far into the neighboring areas of neuroscience, ethology, and evolutionary psychology, that what once seemed impossible – turtle yawning – now has to be officially tested in the lab. It is also appropriate to spread the results of nonsense, as if we would be surprised to find that the turtle is yawning.
The Entire Research Literature On Contagious Yawning Could Be Bogus
That’s what makes the latest study on contagious yawning, published last week, so inflammatory. In a new paper, titled “Are Yawns Really Contagious? A Critique and Quantification of Yawn Contagion,” lead author Rohan Kapitány, a postdoctoral fellow at Oxford University, says that research on this subject has many methodological challenges and these challenges are so large that they have led to spontaneous, naturally occurring interference.
