Introduction
The term phobia is often related to “ When you genuinely fear something for no rational reason” [1] There are three types of phobias; specific, social and agoraphobia. To develop a fear which is irrational allows room to explain reasons to develop a phobia. Classical conditioning and observation are two methods of developing phobias.
Instructional fear acquisition allows us to work out if things are scary; as humans we may even evolve to fear certain things after some time. The brain regions involved are the insular cortex and the amygdala. [1] The numerous methods in treating phobias could be systematic desensitisation, cognitive behavioural therapy and a last resort being antidepressants. From the article there is still very minimal discussion regarding the development of irrational fear and the effectiveness of treatments for phobias. However the different types of phobias are very important in understanding the categories in which individuals can be subjected to.
Throughout the article questions still remain; how is there a development of fear by the definition of irrational? What are the most effective treatments of phobias? And is there a correlation directly to human evolution?
Discussion
Anxiety is a normal reaction to stress, which in some situations can become excessive and affect their day-to-day activities in a undesirable way. There are a numerous different anxiety disorders ranging from post-traumatic stress disorder, obsessive-compulsive disorder, and phobias. Although in the article there is no mention of anxiety but in order to understand the rationale behind irrational fears we have to understand how the brain works in order to relate this to treatment and how development of phobias are created.

  • Fear in William Golding's Lord of the Flies

    Human's fears should not be taken lightly. Fear could do anything to one's minds, though without fear, man can be as savage as animals. In the book Lord of the Flies, William Golding presented fear of the unknown to be a powerful force in a man's mind. Fear of the unknown is a powerful force, which can turn to either insight or hysteria. The kids feared of not being rescued off of the island, so they made signal fires on top of the mountain. Then, there and gone, Roger's fear of the old rules he abided to. Also, there were the fears of the beast which confused and isolated the kids from the top of the mountain.

  • Biological And Environmental Factors In Defining Fear: The Importance Of Fear

    865 Words  | 2 Pages

    Fear is a potent emotional response developed by the intrinsic need to learn in order for one to better their means of self-preservation. Though often overlooked, fear is a mental construct which presents great importance in understanding an individual’s thoughts and mannerisms. Children can help scientists to better recognize how these fears emerge. The early years of life can be considered the most daunting; everything in the environment surrounding a child is fairly new, strange, and unfamiliar. In the psychological community, it is widely accepted that fears are determined from two main constituents: biological and environmental factors. Both factors play an essential role in defining fear as well as the determination of what a child may

  • Biological and Psychological Explanations of Anxiety Disorders

    484 Words  | 1 Pages

    Biological and Psychological Explanations of Anxiety Disorders Research has often concluded that no one biological or psychological theory can provide a sufficient explanation into anxiety disorders such as depression. The diathesis stress model explains psychological anxiety disorders as an interaction between a predisposition to the disorder and environmental stress. In terms of anxiety disorders, predispositions include aspects of biological and psychological factors. Often the main problem found with psychological explanations of anxiety disorders, especially the psychodynamic theory, is that is the theories are more difficult to test. With Freud’s theory, which is largely based on the working of the unconscious mind, it makes it impossible to prove or disprove.

    ... anxiety and it is not a negatively-adapted trait, but rather an instinct that can sometimes seem primitive in such an advanced culture. Reading this article did not provide me with any new approaches to dealing with my anxiety, but the statistic about the disorder’s prevalence on page 56 helped me to feel less alone. Before reading Park’s article, I had never really considered the possibility that anxiety could have positive results or an evolutionary basis intended to improve the chances of survival. For those with anxiety looking for alternative methods of alleviating those feelings or a deeper understanding of the sources of their anxiety, this article may prove a valuable read. People who do not have anxiety themselves could also benefit from reading this article, as it provides an accurate snapshot of the struggles a person suffering from anxiety experiences.

  • The History, Causes and Effects, and Treatment of Phobias

    Just imagine for a moment that you have a cynophobia or the fear of dogs, would this be how you would feel. Driving down the road the oil light comes on. "I must stop the car to add more oil or I will damage the car engine. This looks like a good place to pull over. I'll just stop in front of this house. The oil is in the trunk, so I'll pop the top first, then get the oil out of the trunk. OK, I have the oil, but what if there is a dog at this house. Hurry, I have to hurry. A dog might come running out and bark at me any minute. Just get the oil in the engine. I can't my hands are shaking. Don't worry, there is no dog. Just get the oil in the engine. I don't care if I spill it, just get some in the engine. Take another look around, is there a dog anywhere. OK, the oils in, now hurry get back in the car. I can't breath. I'm safely back in the car, now just take a minute and breath. When will my hands stop shaking." This is how a person with a phobia of dogs might feel. There is no dog around anywhere in sight, but the thought of a dog running at them barking is enough to cause a panic attack. In "Exploring Psychology" David G. Myers defines phobia as "an anxiety disorder marked by a persistent, irrational fear and avoidance of a specific object or situation" (432). This paper will explore the history, causes, effects, and treatment of Phobias.

  • What Are Social Phobias?

    2194 Words  | 5 Pages

    One of the characteristics of a phobia is a feeling that is greater than the fear of a situation or object with an exaggeration of the danger associated with the said situation or even object. This persistent fear often leads to an anxiety disorder that leads an individual to develop mechanisms that ensure one avoids the object or situation that triggers the occurrence of the phobia. Phobias can have highly debilitating effects on an individual including the development of depression, isolation, substance abuse, and even suicide. Many people take phobia for granted however, it is clear that it has the potential to impair the quality of life for both the affected and the people around them. The fact that many of the phobias are manageable using

  • generalized anxiety disorder

    There are many studies pertaining to generalized anxiety disorder. The studies examine the genetic and environmental risks for major anxiety disorders, their course-both alone and when they occur along with other diseases such as depression-and their treatment. Like heart disease and diabetes, these brain disorders are complex and probably result from a combination of genetic, behavioral, developmental, and other factors. Much of the research of anxiety centers on the amygdale, an almond-shaped structure deep within the brain. The amygdale is believed to serve as a communications hub between the parts of the brain that process incoming sensory signals and the parts that interpret them. Other research focuses on the hippocampus, another brain structure that is responsible for processing threatening or traumatic stimuli. By learning more about brain circuitry involved in fear and anxiety, scientists may be able to devise new and more specific treatments for anxiety disorders. Researchers are attempting to learn how genetics and experience interact in each of the anxiety disorders-information they hope will yield clues to prevention and treatment.

  • Tetraphobia Essay

    1408 Words  | 3 Pages

    There’s a monster under your bed, and there are ghosts in the attic. The Bogey man is in your closet and ravens await your death so they can pick from your rotting flesh. Flowers are ready to strangle you, as pickles prepare to choke you in the night. It’s almost funny to hear of people who actually fear flowers and pickles. But these people have real legit fears of even the nicest of things. Although these fears are horrible, and should not be feared; I think the more we know about them, the more we can be prepared. There must be a deeper meaning of these weird phobias. Is it nature? Or inherited traits of the human body? Maybe they come from past experiences? Even as these fears are quite interesting, but unwanted, I want to know why people acquire these ridiculous fears and how we could stop them.

  • The Neurobiology of Anxiety Disorders: A Preliminary Investigation

    When I first began my research for this paper, I was primarily interested in learning more about the role of serotonin in the treatment of anxiety disorders. While I did discover that serotonin is important, especially when it comes to understanding the latest drugs being prescribed by doctors to combat anxiety symptoms, I also learned that researchers are pursuing a number of other "leads" in investigating the neurobiology of anxiety disorders. There has been evidence suggesting that a particular gene, or genes, may be associated with the development of anxiety disorders (1). In addition, the circuitry of the amygdala, an area of the brain that regulates fear responses, is now being studied (2). First, I will briefly summarize my findings regarding serotonin, and then I will offer my own personal reaction. I will focus my response around Social Anxiety Disorder, one of a number of anxiety disorders that are diagnosed and treated today.

  • Thesis Of The Concept Of Fears: The Conception Of Phobias

    793 Words  | 2 Pages

    This paper is focused on how fear as a subject is being perceived by many as a dominant and primitive human emotion. An uncontrollable energy that’s exists and created within every individual, which is directed towards an object or a given situation that does not present an actual danger. The individual then analyzes that the fear is contradictory and thus cannot help the reaction. Gradually, the phobia aims to build up and aggravate as the fear of fear response takes hold. Eventually they distinguish their fear responses as negative, and go out of their way to avoid those reactions. ‘Fear is derived as a basic feeling and therefore created by us – it is not something we have, but something we do. The principle of fear is to keep us safe.’

  • Phobias

    2220 Words  | 5 Pages

    There are three kinds of phobias: simple phobia, social phobia, and panic attacks. Simple phobias, also called specific phobias, are fears of a specific thing, such as spiders or being in a closed place. Most simple phobias develop during childhood and eventually disappear. Specific phobia is a marked fear of a specific object or situation. It is a category for any phobias other than agoraphobia and social phobia. The categories of specific phobias are 1. situational phobias such as: fear of elevators, airplanes, enclosed places, public transportation, tunnels, or bridges; 2. fear of the natural environment such as: storms, water, or heights; 3. animal phobias such as: fear of dogs, snakes, insects, or mice; 4. blood-injection-injury phobia such as: fear of seeing blood or an injury, or of receiving an injection.
