Are you about 16 percent of people experiencing something called tripophobia? It would be an irrational fear of holes and cavities. However, scientists today claim that it can not be accessed as phobia and have good reasons for it.
This is because it is something that is rational and comes from shock, not from fear. These are two very important elements. Scientists at Emory University started investigating the reaction of fear in relation to the pile of holes. The research was published in the journal PeerJ.
They found that pupil response or pupil response (inadvertent pupil movement) – was closer to the pupil's response from disgust, rather than to the one who came out of fear. But it's not just a matter of it.
"Some people have been very upset about this," explained Stella Lourenco, a psychologist from Emory University, whose lab conducted a study. "The phenomenon, which probably has an evolutionary basis, may be more frequent than we knew" .
Previous studies conducted in 2013 concluded that the answer could be to spotted samples of dangerous animals, such as snake. But in January last year a different explanation was pointed out.
Scientists at the University of Kent suggested that pattern holes, such as those found in a bee honeycomb, cause our aversion because they resemble parasitic infestations, contagious diseases and degradation.
"We are an incredibly visual species," said the author of this latest study, Vladislav Ayzenberg. "All this can convey a lot of meaningful information. These visual signs allow us to draw immediate conclusions-whether we see a snake or a snake-and to react quickly to potential danger. "
Scientists recruited tune test students and showed them 60 images. Of these, 20 showed dangerous animals such as spiders and snakes, 20 of them had to activate tripofobia, and 20 pictures were control images and featured harmless animals, coffee beans and repetitive high contrast patterns.
Scientists expected that, as seen in other tests of this nature, students will expand or increase pupils as a reaction to fear – and so it was. Only for dangerous animal pictures.
However, for triggers of tripofobia, pupils were reduced or reduced. And this is known as a pupil's response to disgust.
Scientists have noted that the body's response to nausea acts to slow down the heart rate and breathing, signaling caution and trying to minimize exposure to "pathogens". The reaction of the body to fear is completely different.
Although this team has completed a study with different conclusions from those of 2013, all agree that tripophobia can vary in weight and is more widespread than what is officially reported.
None of the study participants ever regretted the tripophobia, but the physical response to the images was significant.
"The fact is that we have found impacts that suggest a primitive and pervasive visual mechanism that supports the resistance to holes," said Lourenco.
This study will probably not help you feel less embarrassed the next time you see a picture of a surinam frog, but can help you understand how visual processing can result in intense reactions that do not come from fear.
