¶ … classical conditioning by Pavlov and its current use in treating anxiety
The paper focuses on the development of classical conditioning being used, as suggested by Pavlov, in treating anxiety through using fear-induced techniques. The paper talks about the past experiments that were done on animals and human, those who were suffering from anxiety and those who weren't, and highlights how anxiety is treated through fear induced conditioning.
Combination of neutral stimulus with aversive U.S. (unconditioned stimulus) is what we see involved in fear conditioning. In the first stance, there is no emotional response seen from a neutral stimulus, but after the recurring coupling with unconditioned stimulus, the neutral stimulus turn out to be a CS (conditioned stimulus). CS gives indication about the forth coming unconditioned stimulus and brings to mind the nervousness and expectancy with regard to U.S.. Fear conditioning is commonly an adaptive type of learning. When an uneasy response to the conditioned stimulus takes place in the nonexistence of a CS/U.S. possibility then there are chances that fear conditioning may lead to pathology (Lissek et al., 2005).
For the minimum of eighty years, the formal theories have mixed up fear conditioning in the pathogeneses of disorders relating to nervousness (Pavlov, 1927; Watson & Rayner, 1920). Improved quality of work (e.g., Gorman, Kent, Sullivan, & Coplan, 2000; Grillon & Morgan, 1999; Pine, 1999) is trailed from the prologue of extra composite conditioning models where both the aspects of fear and anxiety are noticeable (e.g., Mineka & Zinbarg, 1996). Introduction is followed with research done on animals which define particular lobe circuits which are occupied by terror (reviewed by Blair, Schafe, Bauer, Rodrigues, & LeDoux, 2001). This is followed by facts which support the assistance of related brain parts to fear learning in human beings (e.g., Bechara et al., 1995; LaBar, Gatenby, Gore, LeDoux, & Phelps, 1998). The fear conditioning disparity identified within the anxiety patients is liable to promote the future endeavors which are subject to the explication of neurobiological loci of clinical anxiety.
The declaration of classical conditioning model of anxiety disorders is that the pathological anxiety (neurosis) is developed by simple classical conditioning (Pavlov, 1927; Watson & Rayner, 1920). After the submission of this theory other writers gave an extension to it by stating that classically conditioned model also acts as an instrument which stimulates prevention (Eysenck, 1976, 1979; Eysenck & Rachman, 1965; Miller, 1948; Mowrer, 1947, 1960). The other versions of this theory stress on the birth and the intensification of terror (Eysenck, 1979), the aversive associations prepared on evolutionary basis (e.g., o hman, 1986; Seligman, 1971), failure to slow down the response to safety signs (Davis, Falls & Gewirtz, 2000), related learning shortfall (Grillon, 2002), stimulus generalization (Mineka & Zinbarg, 1996; Watson & Rayner, 1920), and improved condition ability in the arrangement and perseverance of anxiety disorder (Orr et al., 2000; Peri, Ben Shakhar, Orr, & Shalev, 2000),.
Classical Fear Conditioning
Ivan Pavlov (1927) has the honor of demonstrating the original classical conditioning model most eminently. The model starts with the description of certain stimuli which are considered to be unconditional ones, and tend to bring a consistently yielded UR (unconditional response). The model goes beyond to explain that trough training a neutral stimulus could also give the same response when coupled with U.S.. So, under such a situation the neutral stimulus is regarded as the conditioned one and the response generated is the CR (conditioned response). Pavlov performed an experiment on a dog where the food worked as a U.S. And the salivated mouth of the dog was a UR (Pavlov, 1927).
The next time Pavlov offered the food he also rang the bell (neutral stimulus); he repeated this action many times. Finally, he just rang the bell (CS) without presenting the food; just the mere sound of bell produces saliva in the dog's mouth (conditioned response) (Pavlov, 1927).
When the pairing of neutral stimulus is done with aversive one, it is known as Pavlovian fear conditioning. This can be explained with help of an example related to a little eleven-month-old boy, Albert. Once Albert was provided with a rat to play (CS), the boy showed no response of terror. Second time Albert was given the same rat to play but concurrently with a loud sound (U.S.), Albert started to cry (CR). The second step was repeated a number of times and...
