Why Are Some Humans Afraid of Spiders?

Every human have a fear of something. This fear can range from heights, dark places, to several types of animals.

In 1997, Peter Muris of Maastricht University tried to investigate this. In this study, Muris conducted a survey of several children about the things they were most afraid of.

The result, research says that the most feared children are paw-paw. The fear of spiders trumps the fear of kidnapping, wild animals and dark places.

As it turns out, mankind’s fear of spiders has been researched and can be answered scientifically. Here are the reasons why humans can be afraid of spiders according to science.

If you ask several people what spiders fear most, they will likely answer because of their bites. even though Everyday Health reported, of the 40,000 species of spiders, only a few are truly dangerous.

One study from Maastricht University found that something called “spider trauma” was at the root of phobia laba-laba (arachnofobia). These traumatic events are often thought to have occurred during childhood. Even if the traumatic event is forgotten, the fear of spiders will remain.

Scientists from the Max Planck Institute for Human Cognitive and Brain Sciences in Germany have examined the responses of a six-month-old toddler when viewing images of spiders. Apart from the spider, the baby was also shown pictures of flowers, snakes and fish.

During the study, the baby’s pupil will be measured to see the level of noropinephrine which can measure the baby’s stress level. The result, when toddlers looked at the spider image, the pupil was dilated on average 0.14 millimeters (mm). Meanwhile, when the baby saw the flower, the pupil dilation was only 0.03 mm.

“We conclude that the fear of spiders stems from human evolution,” says neurologist Stefanie Hoehl of the Max Planck Institute.

This is the reason why toddlers feel scared and stressed when they see a spider image for the first time. According to Hoehl, the mechanism of the human brain is the same as that of primates, with the ability to identify objects of spiders or snakes with quick reactions.

Uncertain movements

If there was a reason for human evolution, chances are we would think that our ancestors were afraid of spiders for the reason of spider bites.

However, research by Graham Carey from The City University of London, UK, says the most disturbing thing about spiders is their sudden and erratic movements.

“The circumference of their arms seemed to be zipping around in any direction with their very long legs,” Carey said, as quoted. Insider.
