Ivan Pavlov 's Theory Of Classical Conditioning Essay

B.F Skinner was an American Psychologist who invented the operant conditioning chamber. The chamber he set up had rats in it and a lever, once the rats pulled the lever they were given a piece of food. After this happened the rate of bar pressing would increase dramatically and remain high until the rat was no longer hungry. He was a firm believer of the idea that human free will was actually an illusion and any human

Ivan Pavlov (1849-1936) was a Russian psychologist who inadvertently discovered classical conditioning; a way to view the functioning of the nervous system, this remains his greatest psychological contribution

Skinner created the theory of Operant Conditioning as he believed that all behaviour can be controlled by rewards or reinforcement. This is very different from Pavlovs theory of Classical Conditioning as Skinner is trying to control voluntary behaviour. This is done by giving the subject a positive or negative reaction to an action with the theory that a negative response will discourage the subject to repeat the action. A good example of this is house training a dog, as the dogs natural reaction is to relieve itself, however it must be taught to wait until it is outside. The more the dog waits until he is outside, the more praise he receives therefore it is less likely to wish to instigate a negative reaction by relieving himself inside the house.

Burrhus Frederic Skinner was an upcoming behaviorist in the 1920’s. Skinner and many other behaviorists at the time were revolutionizing the field of psychology by deviating away from common practices and methods. Skinner was the most influential behaviorist during this time period as he contributed the greatest by developing a new way of studying behavior, which came to be known as operant conditioning. Before the development of operant conditioning psychologists mainly focused on classical conditioning; a much simpler method for explaining the process of behavior.

While Skinner was at Harvard, he invented what he called an operant conditioning apparatus, known as the Skinner Box. By using this device, Skinner could study an animal interacting with its environment. He started off by studying rodents in the experiments, examining how the rats discovered and used a lever in the box that dispensed food at different times. Skinner then started experimenting with pigeons, using the box. The pigeons pecked at a disc to gain access to food. By conducting these tests Skinner came to the decision that some form of reinforcement was crucial in learning new behaviors. While researching at Harvard, Skinner pronounced the results of his operant conditioning experiments in the Behavior of Organisms (1938).

Current study focuses on the understanding of Molecular Mechanism of Pavlovian conditioning (PC). Pavlovian conditioning is the reference paradigm for the study of associative learning based on the programmed relation of two stimuli, the conditioned stimulus (CS), a tone, and the unconditioned stimulus (US), sucrose-water. Previous research in rodents has revealed that the limbic circuits (or BLA), play an important role in Pavlovian reward learning. We hypothesize that PC acquisition produces a different memory from PC extinction in the BLA. In this study some of the markers analyzed and measured include: atypical Protein Kinase M ζ (PKMζ), Protein Kinase C ι/λ (PKC ι/λ), AMPA (a-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid) receptor subunits glutamate A1 (GluA1), GluA2 and GluA3.These markers are important for consolidation and retrieval of memory.

1904 Nobel Prize Winner, Ivan Pavlov was born in Ryazan, Russia on September 14, 1849. Pavlov is best known for his intricate workings with the drooling dog experiment that lead to his further research in conditioning. This experiment, which began in 1889, had an influence on the development of physiologically oriented behaviorist theories of psychology in the early years of the nineteenth century. His work on the physiology of the digestive glands won him the 1904 Nobel Prize in physiology or medicine.

Ivan Pavlov was a Russian scientist who is famously known for his classical conditioning experiment on dogs, better known as Pavlov’s Dogs. Pavlov originated classical conditioning unintentionally (McLeod). His experiment consisted of a dog, its saliva glands, dog food, and a bell. Pavlov noticed that dogs had natural reflexes and wanted to point out that they did not need to be taught certain things (McLeod). The dog 's’ saliva glands were the main implements while conducting this experiment.

Burrhus Frederic Skinner was born in Susquehanna, Pennsylvania in 1904. As a child he had an interest in literature and loved to construct mechanical toys and gadgets. While he was a teenager he took an interest in the literary works of Francis Bacon and Charles Darwin. He went to Hamilton College in Clinton, New York where he majored in English language and literature. After college he moved to New York City and worked in a book store this is where he discovered Behaviorism. After reading two books by John Watson, the theory of behaviorisms funder, along with Ivan Pavlvo’s Conditioned Reflexes. He then decided to pursue graduate work in Psychology. He enrolled in Harvard University in 1928 he found that his understanding of behaviorism was

Ivan Pavlov was brought into this world on September 14, 1849 in Ryazan, Russia. His father, Peter Dmitrievich Pavlov, happened to be the head priest in the village, so Ivan Pavlov started out in a church school. He aspired to become a priest himself until he started seminary school when he discovered D.I. Pisarev, the most prominent russian literary critic of the time. Pavlov was inspired by Pisarev’s atypical views and ideas. That was when Ivan Pavlov decided to dedicate his life to science, rather than theology (Nobel Lectures). Pavlov transferred to the University of St. Petersburg to learn more having to do with the natural sciences. His professor in psychology, Cyon was very enthusiastic, and Ivan Pavlov respected and honored him. This

He was born in 1849 in Ryazan, Russian Empire. He graduated and received a degree of Candidate of Natural Sciences from the University of St. Petersburg. Pavlov was interested in how digestion worked in animals. Thus, began to observe and record information on what triggered his dogs to salivate. His research led to the understanding that animals salivate because they use saliva to help them break down the food. Therefore, when food was presented the dogs would drool. However, he made an even deeper discovery, Pavlov noticed that his assistants wore long coats. Every time an assistant would be in the lab even if they did not have food the dogs would salivate. (Pavlov, 1927) Pavlov could not understand why dogs would drool at ordinary lab coats. He decided to run an experiment in which he would ring a bell each time he fed the dogs. After a period of time he would just ring the bell and his dogs would immediately salivate. This experiment is what helped develop his theory of classical conditioning a learning process that occurs when two stimuli are repeatedly paired, a response that is at first caused by the second stimulus is eventually produced by the first stimulus alone. Pavlov explained classical conditioning; there is a neutral stimulus (bell) by itself, it will not produce a response, like salivation. There is another stimulus (food), which produces an unconditioned response

One of the most renowned psychologist of the 20th century known as Burrhus Frederic Skinner is described to have been a "highly conscientious ,extroverted and somewhat neurotic" man. (article 2). Skinner believed that "our actions are shaped by our experience of reward and punishment" (article 4) a term coined by Skinner himself as operant conditioning. Skinner was born on March 20, 1904 in Susquehanna, Pennsylvania into a "warm and stable environment" (Article 1). Skinner had one younger brother who died of a cerebral aneurysm at the age of 16. His father was a lawyer and his mother was a house wife. During Skinner 's childhood he "showed an interest in building different gadgets and contraptions" (article 5) such as a perpetual motion machine and a cart with a steering wheel. This interest would later serve him well in his research in behaviorism.

The American psychologist B.F. Skinner was the first to recognize that operant conditioning could be used to shape behavior.

Burrhus Frederick (B.F.) Skinner was a Psychologist who had a major influence on the field of education with his work in Operant Conditioning. I chose to do my research and project on this particular Psychologist because he is a name that I remember coming up throughout the years of school. I remember hearing about the Skinner box and experiments that he had done. When I started to research, he was one of the Theorist that continued to appear and it was interesting to read about him and his work.

B F Skinner was one of the most influential behaviourist in psychology. He introduced a lot of new theories from his work and has been studied by many for years. Skinner particularly focused on behaviour patterns of animals and people, of course. He was very popular for his “Skinner Box” experiment. Skinner Box is used for conditioning animals like pigeons and rats to behave in desired ways such as running through a maze, playing tunes on a keyboard, or pressing levers (McLeod, 2007). Skinner also influenced the education field through his theory that behaviour was important and good behaviour should be reinforced with rewards and bad behaviour should be negatively reinforced or punished (McLeod, 2007). Skinner is known as the father of Operant Conditioning and introduced a new term Reinforcement as his work was based on Thorndike’s Law of Effect.
