Humans Born With A Natural Fear Of Spiders
May 14, 2020
Spiders provoke fear and revulsion in both adults and infants. But what is it about spiders and their eight legs, fat and fury, thin dark needle-like bodies, that inflicts a fear for them within us? Researchers from Germany and Sweden decided to find out by testing a specific segment of our population least likely to show fear: babies.
They started by analyzing a group of 48, six-month-old infants, and recorded their reactions to images. The infants while seated in the comfort of their parents, were shown images of spiders and snake for five seconds each. The parents were not allowed to see the images. This was done so that they did not influence the reactions of their infants. The scientists recorded different kinds of data, especially pupil dilation, because dilated pupils are associated with brain neural activity, which processes stress.
The results astonished everyone. When the babies saw images of spiders, they reacted with larger pupils than when other controlled images of fish and flowers were shown. Another contradictory study shows people aren’t born afraid of spiders. Instead, it is learned during infancy. It is said that natural selection may have played its part in favoring people who stayed away from these creatures. Therefore, several studies show that both humans and apes learn to fear evolutionarily threatening things than non-threatening things. It is said that spiders presented a great danger to humans during the early stages of our evolution. This fear of spiders has now become a part of our DNA.
The fear of spiders is termed as arachnophobia. Spiders tick all the boxes, like any other phobia. As time passes it builds up in our minds and we become so fearful of them that even seeing a picture of spiders will send chills down our spines. Spiders are found everywhere in America and some are a cause of concern for homeowners with small children and pets. The most common spiders found in San Antonio are Brown recluse, Black Widow, House spider, and Wolf Spider. You should avoid contact with Brown recluses and Black widow spiders.
