Why women are afraid of spiders?

Now you should not think that sisters are afraid of spiders or snakes, but they are shy.American scientists have recently discovered that women fear these animals because of the evolutionary decision.

Carnegie Mellon University professor David Rakison found 10 boys and 10 11-month-old girls to participate in the experiment. They left images of spiders and images that showed fear to the children, letting them know that spiders are scary animals.

After that, they showed the kids two other types of images. Type 1 is spider and shows joy; Type 2 is flower and expresses fear. The results showed that the time for girls to see images of type 1 was longer than type 2; while the time to see two types of photos of boys are the same.

David Rakison said that girls look at photos of type 1 longer, because they believe that spider images and expressions of fear must be placed side by side, rather than expressing joy ; boys do not have any connection between spiders and fear.

Experimental results show that, when comparing girls and boys at 11 months of age, girls will form a faster relationship of fearful objects such as spiders, snakes and manifestations. pole. The research results will be published in the journal Human Behavior and Evolution (Evolution and Human Behavior).

David Rakison said, girls will learn faster than fear for dangerous animals. He adopted the different sex responses of spiders and drew conclusions about the evolutionary results: a sense of fear can help women in previous societies avoid dangerous animal attacks. But men in the hunting process are forced to overcome fear.

David Rakison further explained, in the previous society, a man could have children with many women, so compared to men, women will have fewer children, moreover they are responsible for looking after children. . If they were attacked by a poisonous spider or snake, they would not be able to continue taking care of their children; if they lose their mother, they will almost lose their ability to survive.

' But men in the hunting process are forced to risk. They have no other choice, to face fear, "he said.

Women of certain ages will learn the fear of dangerous animals, not the innate shyness.

While conducting experiments with another 11-month-old group, David Rakison showed boys and girls in turn the spider photos and smiles; flowers and express fear. The result is the same time to observe photos of girls.

He said: ' Girls have no reason to fear spider images. They were only scared after being attacked, then crawled away. '

Survey results show that about 5.5% of adults and children are afraid of snakes, 3.5% are afraid of spiders. Women are four times more afraid of spiders, snakes and other dangerous animals than men. But women who are afraid of flying and injecting are no more than men.
David Rakison said: ' So women are not innocent shy .'
