Spider Fears or Arachnophobia

Understanding Spider Fears

By

Updated June 03, 2009

Arachnophobia, or fear of spiders, is one of the most common specific phobias. Those who are afraid of spiders will go to great lengths to ensure that they are not exposed to a spider. They may be unwilling to participate in activities, such as hiking or camping, that carry a heightened risk of exposure to spiders.

Symptoms of Arachnophobia

If you have arachnophobia, you will probably go out of your way to ensure that you do not come in to contact with a spider. If you find a spider in your home, you may react in one of two ways: either screaming and running away or freezing in place. You may be unable to kill or trap the spider yourself, relying on a friend or family member to rescue you from the situation. If you are alone, you may actually leave the house rather than deal with the spider.

Eventually you may find yourself limiting your activities in an effort to avoid spiders. Hiking and camping trips may be difficult or impossible for you. You may even dread visiting the zoo or participating in sports that involve being outside in a field.

Causes of Arachnophobia

Experts are still uncertain what causes arachnophobia. There a few theories, though. One of the most common theories was put forth by evolutionary psychologists. This view suggests that arachnophobia was a survival technique for our ancestors. Since most spiders are venomous, although most do not pose a threat to humans, a fear of spiders may have made humans more likely to survive and reproduce.

Other psychologists argue that many animals were more likely to pose a threat to ancient humans, from tigers to crocodiles. Yet phobias of those animals are not that common. Therefore, those psychologists feel that arachnophobia is more likely based on cultural beliefs about the nature of spiders.

Treating Arachnophobia

Like all specific phobias, arachnophobia is most commonly treated through therapy, particularly cognitive-behavioral techniques. Antidepressant or anti-anxiety medications may also be used. Some newer research has shown that virtual reality therapy, in which the sufferer is exposed to virtual representations of spiders, may work as well as the older technique of gradually exposing the client to live spiders.
