It is estimated that more than 40% of the general population suffers from one or more fears towards a specific object or situation (Williams 1987). If the fear becomes excessive or unreasonable, it is called a phobia. Phobias can lead to significant impairments in daily life (Vigerland 2013). Specific phobia is an anxiety disorder defined as an unreasonable or irrational fear that has a negative impact on daily life, with a lifetime prevalence rate greater than 10%, specific phobias are the most widespread group of disorders mental. Five main categories are distinguished: animal type, natural environment type, situational type, blood wound-injection type, and other type (Van Houtem 2013). Specific phobia subtypes differ markedly in terms of prevalence, sex distribution, and age of onset (Burnstein 2012). The development of specific phobia can be better understood through the classical conditioning model; the pairing of a conditioned stimulus with an unconditioned stimulus that automatically evokes a fear response (e.g. Watson & Rayner 1920). Conditioning theory states that irrationally feared objects and situations resemble previous distressing experiences (Van Houtem 2013). For a number of specific phobias other factors, including genetic predisposition (see Van Houtem 2013), may play a role in the development of specific phobias. Specific phobias can be treated in several ways, the most effective being one-session treatments (Ollendick & Davis 2013) and cognitive behavioral therapy (see Vigerland 2013). Children may be conditioned to express emotional reactions in certain situations or to certain stimuli. This conditioning can occur intentionally, as in the study described below, or unintentionally (Watson & Rayner 1920). And...... half of the paper ......ol group, indicating that the results should be interpreted with caution (Vigerland 2013). A large percentage of the general population suffers from a specific phobia, or the possibility of obtaining a specific phobia during their lifetime (Williams 1987). A specific phobia, named so because of the excessive or unreasonable fear it exerts in an individual (Van Houtem 2013), has the ability to inhibit or seriously affect an individual's daily life. Blood injection type and other type are the most dominant phobias affecting the general population. Specific phobias can be developed in several ways, including pairing a conditioned stimulus with an unconditioned stimulus that automatically evokes a fear response and genetic susceptibility (Van Houtem 2013). Specific Phobias often resemble previous painful experiences (Van Houtem 2013).
