Evolution Of Aversion: Why Even Children Are Fearful Of Snakes
Some of the oldest tales and wisest mythology allude to the snake as a mischievous seducer, dangerous foe or powerful iconoclast; however, the legend surrounding this proverbial predator may not be based solely on fantasy. As scientists from the University of Virginia recently discovered, the common fear of snakes may well be intrinsic.
Evolutionarily speaking, early humans who were capable of surviving the dangers of an uncivilized society adapted accordingly. And the same can be said of the common fear of certain animals, such as spiders and snakes: The ancestors of modern humans were either abnormally lucky or extraordinarily capable of detecting and deterring the threat of, for example, a poisonous snake.
Psychologists Vanessa LoBue and Judy DeLoache were able to show this phenomenon by examining the ability of adults and children to pinpoint snakes among other nonthreatening objects in pictures.
“We wanted to know whether preschool children, who have much less experience with natural threats than adults, would detect the presence of snakes as quickly as their parents,” LoBue explained. “If there is an evolved tendency in humans for the rapid detection of snakes, it should appear in young children as well as their elders.”
Preschool children and their parents were shown nine color photographs on a computer screen and were asked to find either the single snake among eight flowers, frogs or caterpillars, or the single nonthreatening item among eight snakes. As the study surprisingly shows, parents and their children identified snakes more rapidly than they detected the other stimuli, despite the gap in age and experience.
LoBue and DeLoache also found that both children and adults who don't fear snakes are just as good at quickly identifying them as children and adults who do fear snakes, indicating that there may be a universal human ability to visually detect snakes whether there is or is not a fear factor based on a learned bias or experience.
LoBue and DeLoache explain that their study does not prove an innate fear of snakes, only that humans, including young children, seem to have an innate ability to quickly identify a snake from among other things. One of their previous studies indicated that humans also have a profound ability to identify spiders from among non-threatening flora and fauna. Lobue has also shown that people are very good at quickly detecting threats of many types, including aggressive facial expressions.
The results, which appear in the March 2008 issue of Psychological Science, a journal of the Association for Psychological Science, may provide the first evidence of an adapted, visually-stimulated fear mechanism in humans.

Study: All humans have innate fear of things moving closer to them
A new study from the University of Chicago finds that all humans have an innate sense built in that makes us fear things that are moving closer towards, rather than moving away.
In evolutionary terms, this makes sense. Early humans were nowhere near as equipped to deal with danger as we are now -- so a wild animal or a person we don't know approaching us could be a sign of potential danger.
Nowadays, we don't have to worry about that as much. But even so, that aspect of our personalities has apparently stuck around. Modern humans continue to experience what we call "approach avoidance," even when the things or people approaching us, are non-threatening.
For this study, researchers conducted eight different tests, using everything from sounds to videos of people walking towards you -- even objectively innocuous things, like letters of the English alphabet getting bigger and bigger. The goal was to see if objects that looked or sounded like they were getting closer would elicit fear within a group of test subjects.
... And they did. All of them.
This doesn't just apply to physical objects. It also extends to events that are approaching in time, or increasing in likelihood.
According to Christopher Hsee, the researcher who authored the study, "Approach avoidance is a general tendency." And for one reason or another, humans can't seem to adequately distinguish between times they should use it and times they should not.

Fear is an emotion induced by a threat perceived by living entities, which causes a change in brain and organ function and ultimately a change in behavior, such as running away, hiding or freezing from traumatic events. Fear may occur in response to a specific stimulus happening in the present, or to a future situation, which is perceived as risk to health or life, status, power, security, or, in the case of humans, wealth or anything held valuable.
The fear response arises from the perception of danger leading to confrontation with or escape from/avoiding the threat (also known as the fight-or-flight response), which in extreme cases of fear (horror and terror) can be a freeze response or paralysis.
In humans and animals, fear is modulated by the process of cognition and learning. Thus fear is judged as rational or appropriate and irrational or inappropriate. An irrational fear is called a phobia.
Psychologists such as John B. Watson, Robert Plutchik, and Paul Ekman have suggested that there is only a small set of basic or innate emotions and that fear is one of them. This hypothesized set includes such emotions as joy, sadness, fright, dread, horror, panic, anxiety, acute stress reaction and anger.
Fear is closely related to, but should be distinguished from, the emotion "anxiety", which occurs as the result of threats that are perceived to be uncontrollable or unavoidable.
The fear response serves survival by generating appropriate behavioral responses, so it has been preserved throughout evolution

- I noted that when dreaming, i usually get really scared of knifes, swords, any bladed weapon, would be that because fire-weapons are really recent in human story, and the bladed ones, or even wood spears been aroud since forever?
