Classical conditioning is the first type of learning to be discovered and studied by behaviorists. In classical conditioning, no new behaviors are learned, but rather associated or paired with something else. In the early 1900’s a Russian physician and physiologist, Ivan Pavlov, was studying digestion in dogs, when he observed something remarkable about their behavior. Pavlov built a mechanism to measure the salivation of dogs when they were fed a meat powder. He monitored their natural reaction to the powder by attaching tubes to their salivary glands. Pavlov soon noticed that his dogs began salivating when they observed a sight, sound, or smell that they had come to associate with being fed. After observing the dogs’ association, he …show more content…
Unlike Pavlov’s dogs that stopped salivating when the bell stopped, the child would continue to be afraid of these things because we are hard wired to avoid things that we fear or that may bring us harm. Without being unconditioned to the response, the child would likely go through life being afraid of the conditioned stimulus. Cases of classical conditioning can be observed in our everyday lives. About two years ago I adopted a kitten from a local family. The kitten was an outside cat in which the family fed dry cat food. When I brought the kitten home, I began feeding her twice a day, a wet cat food. I opened the cans with an electric can opener when I fed her, the sound would always frighten her away. She would run and hide, and I would have to try and coax her out from under my bed, or where ever else she decided to take refuge. The electric can opener was the unconditioned stimulus (UCS), and her fear of the can opener was her natural, unconditioned response (UCR). After a few days, whenever I opened her cat food she would wait until the can opener stopped and sly into the kitchen after a minute or two once she was certain there was no threat to
Kurayama, Matsuzawa, Komiya, Nakazawa, Yoshida, Shimizu, (2012) confirmed that these neutral stimuluses deed indeed has an effect and played a role in fear conditioning in people. The case showed that Treena had indeed learned to be scared of the incident and it proceeded to become a cue for to get anxious and get panic attacks. It has been claimed that patients with panic disorder exhibited fear potentiated startle responses to safety cues and therefore reduced discrimination between safety and danger signals during acquisition, indicating that the safety signal was processed as the aversive event in contrast to the danger signal (Nees, Heinrich, Flor, 2015). It also showed that the her failing to answer the question had affected her in other classes when she would not participate in other classes hence, this showed that the neutral stimulus has developed and grew into a conditioned stimulus which evoked feelings of fear and anxiety in her, in other words it had become a cue for her to be scared and
Fear conditioning is a commonly used behavioral paradigm to test an organism’s ability to create associations and learn to avoid aversive stimuli. There are two methodologies: cue and contextual fear conditioning (Kim & Jung, 2006). In cued fear conditioning, a neutral conditioned stimulus (CS) is paired with an aversive unconditioned stimulus (US) which activates a strong unconditioned fear responses (UR). After a continued training period, the neutral CS is now able to activate a conditioned response (CR). Similarly, context conditioning occurs when the background or context cues, during the condition training, is able to predict the US and activate the fear response. For example, a mice can be placed in a novel environment and given an aversive stimulus (e.g. footshock). When the mice is returned to that same environment, it will display a CR (e.g. freezing). The mice’s ability for contextual fear conditioning is dependent on whether it was able to learn and associate its environment with the aversive stimulus. (Curzon, Rustay, and Browman, 2009)
using a bell to trigger the dog's salivary glands. Before conditoning, there has to be a neutral stimulus before a reflex occurs. During this process, a unconditioned stimulus will result in a uncondtioned response. During the second phase, the neutral stimulus is continuously paired with the unconditional stimulus. As a result, a connection between the neutral stimulus and unconditional stimulus. Now the neutral
The study by Watson and Rayner was to further the research of Ivan Pavlov. Pavlov was a Russian physiologist whose most famous experiments involved that of animals, specifically the unconditioned and conditioned reflexes of canines, in reference to salivation and conditioned emotional response. Pavlov demonstrated that if a bell was rang each time a dog was fed; ultimately the animal would befall conditioned to salivate at just the sound of the bell, even where food is was no longer present (The Salivation reflex). Watson and Rayner set out to further the research of conditioned stimulus response, with little Albert. ‘These authors without adequate experimental evidence advanced the view that this range was increased by means of conditioned reflex factors.’ (B.Watson, R Rayner , 1920).
One of the most famous of experiments that illustrates classical conditioning is Pavlov's Dogs. In this experiment, Pavlov sat behind a one-way mirror and controlled the presentation of a bell. The bell was the conditioned stimulus. A conditioned stimulus was an originally neutral stimulus that could eventually produce a desired response when presented alone. Directly after the ringing of the bell, Pavlov gave the dog food. The food was the unconditioned stimulus. This means that the food caused an uncontrollable response whenever it was presented alone. That response would be the salivation of the dog. A tube that was in the dog's mouth then measured the saliva. When the unconditioned stimulus (US) was paired with a conditioned stimulus (CS), it eventually resulted in a conditioned response. Extinction results if there is a decrease in frequency or strength of a learned response due to the failure to continue to pair the US and the CS.
The most famous behaviorist experiment is also one of the simplest example, in which Ivan Pavlov induced such a significant association in dogs (test subjects), that they would salivate at the sound of a ringing bell, because he had taught them to associate the sound with food. Emphasis within the behaviorist approach itself range from simply observing behavior as a convenient heuristic of psychological research, a branch that uses only behavior to gauge psychological processes, and a third that only behavior is relevant to the study of the human mind, as less observable terms refer only to behavior.
Behaviorism and conditioning has its share of success stories especially when used to curb undesirable habits such as smoking and drinking, however they have also had their moments of darkness as well as seen in 1920 with John Watson and his little experiments that starred a young boy dubbed Little Albert. During Watson’s experiments to help explain conditioning, During his experiments Watson exposed Albert to a number of animals and recorded Albert’s initial reactions which were next to none at all. Watson then began exposing the same animals to Albert, and providing loud bangs that startled Albert at the same time. Eventually Albert began to cry at the sight of the animals even when they were not seen simultaneously with the loud bang.
Russian physiologist Ivan Pavlov in the early 1900’s while making an attempt to better understand digestion accidently stumble on what we now know as classical conditioning (Ormrod, 2012, p. 34). Using dogs, a bell and meat powder, Pavlov discovered when a stimulus that give a unconditioned

We have all heard of Pavlov's Dogs, the experiment where the dogs "drooled" at the sounding of a bell. But, do we know of the details of this infamous experiment? What do we know of the man, beyond that he could ring bells? It is my intention, in this brief dissertation, to shed more light on his life and his experiments.

I. Introduction of classical conditioning Classical conditioning also called as Pavlovian conditioning or respondent conditioning. It is a kind of learning a new behavior through association that when a conditioned stimulus (CS) is paired with an unconditioned stimulus (US) and evokes a conditioned response (CR). It also is a learning process that occurs through associations between an environmental stimulus and a naturally occurring stimulus (Cherry, 2014). Classical conditioning has much strength such as can help to explain all aspects of human behavior and many of advertisers will use classical conditioning to advertise their produces, however it also have some weaknesses such as all classical conditioning responses must involve a reflex and classical conditioning is a completely physical process, learning is not important as reflected in scenario. This paper will talk about the strengths and the weaknesses of classical conditioning theory followed by a brief description of the scenario and the strengths and weaknesses of applying classical conditioning on it.
The theory of behaviorism was later advanced by JB Watson who argued that any behavior can be instilled in a child. Watson argued that any child can be classically conditioned to become anything or to acquire any behavior. The study off classical conditioning involves presenting to an animal or organism to a conditioned stimulus. There is no connection between the conditioned stimulus and the organism. The organism is then exposed to an unconditional stimulus which is then followed repetitively with the exposition of the conditioned stimulus over a certain number of times until the organism learns to associate the conditioned stimulus with the unconditioned stimulus to produce a conditioned response even at the absence of an unconditioned response. In the process the organism was found to elicit an unconditional response at the exposure to the conditioned stimulus.
Many psychologists have contributed to behaviorism becoming the approach that is today. Behaviorism was first presented by the American psychologist John B.Watson. The new concept that Watson presented perceived behavior as a physiological response to environmental stimuli. He disagreed with the belief that mental processes could not be studied scientifically (Behaviorism, 2013). Watson sought to make psychology “a purely objective, experimental branch of natural science,” with conditioning as one of its chief methods (Irvine, 2007). Watson took an extreme standpoint on environmentalism and stated that personality can be created (Irvine, 2007).
(Porter. B., 2013) unconditional stimulus would mean noise. Every Time the child hears that loud clashing sound the bar hitting the steel, it would cause the child to have abnormal breathing showing that he was terrified & was feared of the white rat and the steel bar. (Porter. B., 2013) Conditioned stimulus would represent The Rat the sounds repeats itself, after the unconditional stimulus it would let the child know that both sounds go together. (Porter. B., 2013). The child would always cry a lot when these noises kept coming back to back .This would be consider the Conditioned response which related to Crying and Fear. This would be the response from comparing the two together the white rat and the steel bar and trying educated the child that both theses go
