Afraid Of Snakes? It May Be Hardwired

Study Shows Humans May Be Genetically Predisposed To Ophidiophobia

(AP)  Two University of Virginia researchers believe that humans are genetically predisposed to be deathly afraid of snakes.

Judy S. DeLoache, a U.Va. professor of developmental psychology, said she has a snake phobia, but wonders why. "The question was, where did that fear come from?"

She believes it's because snakes would have posed a significant threat to our ancestors, so a fear of snakes remains hardwired into human brains today.

DeLoache said an experiment she conducted with graduate student Vanessa LoBue proved that adults and preschool children have an extraordinary ability to quickly pinpoint snakes amid harmless distractions.

They conducted three experiments with 24 adults and 24 3-year-olds. Both groups were shown a large touch-screen computer monitor that displayed nine color photographs.

They asked half of the people to find the single image of a snake among non-threatening pictures of caterpillars, flowers or frogs. The second group was told to find the single photo of a single non-threatening item among eight images of snakes.

The researchers found that adults and children were much faster at discovering snakes than they were at locating non-threatening flora or fauna.

The finding that children saw the snakes as rapidly as adults is particularly fascinating, LoBue said, because preschool children tend to be fearless and are less likely to have had a negative experience with snakes.

DeLoache's and LoBue's findings will be published in the March issue of Psychological Science, a journal of the Association for Psychological Science.

LoBue said she has found similar results when testing for an innate fear of spiders. Much like snakes, some spiders would have posed a deadly threat to pre-humans. That study is currently under peer review, she said.

"It's really neat," she said. "We have an evolutionary bias against snakes and spiders."

Virginia is home to three types of venomous snakes - copperheads, canebrake rattlesnakes and timber rattlers.

Julia Dixon, spokeswoman for the Virginia Department of Game and Inland Fisheries, thinks snakes have a bad rap, and said her agency spends time defending snakes.

"The general public out there thinks that the only good snake is a dead snake," Dixon said. But she notes that snakes are a key piece of the food chain because they eat mice, rats and other snakes.

Dixon said the easiest way to identify dangerous snakes in Virginia is to look into their eyes. Virginia's venomous snakes have vertical pupils, similar to a cat's eye, and harmless snakes have round pupils.

Either way, it is usually best to leave the snake alone, she said.

kkcbs... i''m with you! They give me the heevy geevies! They''re the only thing I''m afraid of, rats, mice, bats, lizards, spiders don''t get even 1/100 of the reaction from me as a harmless garter snake. I''ve tried to tell myself I''m being unreasonable, but it just doesn''t seem to work.

Lots of snakes have died around this homestead. After close examination, 100% died of lead poison. Maybe it''s because the old 12 quage will reach out and touch them. I know some snake lover will gripe about this but I had rather buy rat and mouse poison, than have a snake around.

DANG! You sound like Uncle Joe! He always said there are only four kinds of snakes he is afraid of; big ones and little ones and live ones and dead ones!

Me, I like to catch them, see them up close. I always release them unharmed; they aren''t much fun to play with if you kill them first. Besides, they help keep a lot of the pest (varmints and vermin) under control. They''re pretty cool if you aren''t afraid of them.

I think snakes are fascinating creatures. I''ve never been afraid of snakes. They are absolutely beautiful! The way they move is captivating. AND, that they take care of rats, mice, etc., is a serious perk! I''d rather have a nice, quiet, working snake around than poison that other animals will get into. Snakes are great!!!

I like snakes. Never been afraid of them. Now spiders, on the other hand, provoke a serious phobia. Not true arachnophobia, because I think scorpions are cool, just those creepy spiders. Tarantulas are OK, too, since I can see them coming. It''s just the smaller ones that sneak up on you.

P.S. "Religion is the sigh of the oppressed creature...It is the opium of the people."

Virginia is right next to D.C. and there are 2 deadly snakes in the Whitehouse right now. But fear not, they''''ll be gone in just over 10 months. Yippee!!!

I would disagree with this research. I believe that all fear are learned and all fears can be explained rationally and therefore conquered.

Just give him a photo of his ancestor King George of the Jungle and see him exude his pride and chill, then, go into the other room before you laugh at him, you know, to spare his feelings.

Snakes are pretty neat. I steer clear of the poisonous ones but garter snakes are fun to pick up a play with.

Now spiders and bugs.... I don''t like spiders and bugs.

I have never been afraid of snakes, once I picked up a rattler, put it in a bucket, and released it in the desert. I have owned a python, selling it because My landlord objected to it. In Hollywood Ca, we often found and made pets of gopher snakes, great for the rats that were after the avocados on our tree.

In Indonesia, it is common to see dinner-plate sized wood spiders, I find them fascinating and beautiful, shiny black with bright red, or bright yellow patterns and joints, they spin large orb webs, which can be four feet in diameter, on support lines fifty feet long.

I won''t try to handle them because they have long fangs, and bite reflexively. This is not fear, but it is from knowing the character of these creatures.

I can''t totally agree that we become hard wired to dangerous creatures, one reason is called the puss caterpillar. The cutest little ball of orange fur, anyone who has ever touched one can tell you that will cause some major league pain, a few of these little "tribbles" would probably kill you from pain shock. Google a picture of a puss caterpillar, and see if you feel an instinctive fear, I doubt it, but these creatures have been around for millions of years, so it seems that conditioning still plays the major role in arachnophobia, or ophidiophobia

That is *** I have no fear of snakes my Mother has no fear of snakes, my Father had no fear of snakes, my niece has no fear of snakes. We all like them. I hardly think we are freaks of nature! We come from a family who are all into biology. I caught snakes as a small child and even after being bitten at five found I had zero fear afterwards. I do respect poisenous snakes and avoid them. I don''t keep any as pets but enjoy them very much. My husband also has no fear of snakes. I think the fear is passed down in families

"I like snakes. Never been afraid of them. Now spiders, on the other hand, provoke a serious phobia." posted by rf35

Hahaha, me too. I could handle a tarantula but not the smaller ones.

I found a spider on my deck chair last summer and it freaked me the hell out. I had never seen one like it before. It was bigger than most spiders I have seen around here. I didn''t rest until I found out what it was. Actually to be truthful, I was in PANIC MODE because I was afraid that it may be poisonous.

There was something about it''s legs that reminded me of one of those little jumping spiders. I went on Google and found out that that is what it was. It was the largest of the species. It isn''t poisonous but you will definitely feel it''s bite.

When you come accross a really sneaky low down character, don''t you call him/her a snake in the grass?

You people telling that you aren''t afraid of snakes and never have been, are full of it. every one of you would *** a brick if a snake fell out of a tree and landed on your shoulders. I am afraid of snakes but handle them all the time, I use to keep a little worm snake wrapped around my wrist when I was youngster. (just to freak out the girls). Do not confuse familiarity with a lack of fear. I can handle fire without messing my pants, that doesn''t mean I am not fearful of its potential. Get real and be truthful with yourself about fear.

Ever looked eye-to-eye with a very large cobra, which can easily lift its head and body six feet off the ground? Most interesting indeed.

Most people are surprised when an unexpected sudden event happens, I believe that if a pigeon, or a frisbee suddenly landed unexpectedly on ones'' shoulder, you would see the same reaction.

You confuse event shock with innate fear, this is an incorrect association.

yeah but once you find out that what hit you in the neck was a frisbee is no big deal, but if a black mamba just bit your neck, you would sh it your pants because you know you are dead. There is a little difference. The same thin would happen if you have a black mamba a frisbee in front of you. Which of the two would make you more afraid?

Neither. If I am aware of it, I know whether I can get close or not, It I am not aware of it, it will still surprise, regardless of whether snake, or frisbee.

There is a you tube video of a baby, not yet able to walk, playing with a live defanged cobra, the snake strikes repeatedly, the baby is not the least bit bothered, even grabbing the animal, out of curiosity.

While I would say that the video is a disturbing example of cruelty to animals, and also bordering on child endangerment, the child is clearly not afraid, not really knowing what the snake is. If we were "hard wired" to be afraid, the child wouldn''t have to know what it is to show a fear of it.

I agree with the results of the research. My two year old daughter was terrified of a black snake-like string on the floor. She wouldn't walk anywhere near it and I had to pick it up and throw it away before she would calm down.
