Discussion on Classical Conditioning as an Explanation of...

Discussion on Classical Conditioning as an Explanation of Learning We use the term classical conditioning to describe one type of associative learning in which there is no contingency between response and reinforcer. This situation resembles most closely the experiment from Pavlov in the 1920s, where he trained his dogs to associate a bell ring with a food-reward. In such experiments, the subject initially shows weak or no response to a conditioned stimulus (CS, e.g. the bell), but a measurable unconditioned response (UCR, e.g. saliva production) to an unconditioned stimulus (UCS, e.g. food). In the course of the training, the CS is repeatedly presented together with the UCS; eventually the subject forms an association between†¦show more content†¦If a CS is repeatedly presented without the unconditioned stimulus, the CR will disappear. In Pavlovs case, if a dog learns to associate the sound of a bell with food and then the bell is rung repeatedly but no food appears, the dog will soon stop salivating to the bell. Another principle to classical conditioning is the spontaneous recovery. Supposing that a response is classically conditioned then extinguished. If a few hours or days later, the CS is presented again, the CR will probably reappear. As spontaneous recovery is a term used for this temporary return of an extinguished response after a delay. Thus, the elimination of a conditioned response usually requires more than one extinction lesson. Pavlovs dog who was conditioned to salivate to the sound of a bell of one tone may well salivate to a similar sounding bell or a buzzer. Stimulus generalisation is the extension of the conditioned response from the original stimulus to a similar stimuli. The conditioned response to a similar stimulus is not as strong as the response to the original stimulus; the less similar the weaker the response. An animal or person can be taught to choose between stimuli, that is to discriminate stimuli. For example, is a dog is shown a red circle everytime he is fed, then he will salivate at the sight of the red circle alone. However, the dog will usually generalise this response to that they may respond to circles of other colours. If we only feed theShow MoreRelatedPhobias and Addictions Related to Classical and Operant Conditioning865 Words   |  4 PagesAddictions as Related to Classical and Operant Conditioning Introduction People can become conditioned to respond to various stimuli in positive and negative ways, including phobias and addictions. In order to better understand how stimuli elicit phobic or addictive responses, this paper provides a discussion concerning phobias and addictions as related to classical and operant conditioning, including explorations of how phobias can be developed through classical conditioning and how addictions canRead MoreEssay on Week 2 Worksheet871 Words   |  4 Pagesscenario: Kara is 10 years old. She has been given an intelligence test. Her mental age is 13. According to Sternberg, what is Kara’s IQ? Conduct research and interpret her score. Choose two theories of intelligence. Write a 150- to 200-word discussion on the components of each theory, and how they differ in relation to Spearman’s g factor. According to Sternberg, Kara’s IQ is 90 because at ages 10,11,12,13 the level of IQ is more than ages above 17 because of initiation to adulthood. Kara’sRead MoreClassical Conditioning : Why Does Pavlov s Model Work1417 Words   |  6 Pages Classical Conditioning: Why Does Pavlov’s Model Work Why Does it Matter? Rebecca Leap Gardner-Webb University If you were to pull a random individual off the street and ask them to tell you about Pavlov and his dogs, there is a fair chance he or she would be able to give you, at the very least, a basic explanation of how the canines learned to salivate at the sound of a bell. Ivan Pavlov’s experiment has found its way into the cultural lexicon and is often referenced, but those outsideRead MoreIvan Pavlov s Theory Of The Conditioned Reflex1706 Words   |  7 PagesHis name was Ivan Petrovich Pavlov. Ivan Pavlov conducted a well-known experiment for teaching a hungry dog to salivate at the sound of a bell when presented with food. This experiment led Ivan Pavlov to become known for his development on Classical Conditioning, which captured the attention of everyone, especially physiologist and psychologist. Ivan Pavlov was born September, 14, 1849 in Russia. Ivan Pavlov’s father was a priest and his mother was a homemaker. Initially, Pavlov studied theology byRead MoreBenefits And Limitations Of A Physical Education Learning Theory1351 Words   |  6 Pagesof a Physical Education learning theory. In doing so, the selected learning theory will be compared and contrasted with basic learning theories and concepts. Firstly, the selected learning theory will be outlined. Secondly, this paper will discuss behaviourist approach to learning. Finally, to summaries this paper, the reader will get a greater understanding ofbehaviourist approach to learning.To put this discussion into context there now follows a definition of learning and a brief descriptionRead MoreThe Human Mind For Millennia Essay1430 Words   |  6 PagesSelf-efficacy can be defined as successfully completing tasks, which adds to the understanding of dutifulness because it extends the definition to not only following rules, but completing tasks well while following rules. Theoretical Perspectives Explanations Trait Perspective In order to best understand how to analyze dutifulness according to the trait perspective, the history of this perspective is useful. This perspective has its beginnings with Hippocrates and his exploration of four groups forRead MoreThe Theories And Theories Of Learning And Education1026 Words   |  5 PagesThe ways in which children learn is variable, learning practices and singular theories cannot explain by themselves the very process of learning but gives some idea when these theories are viewed simultaneously; working through the limitations and expressing the benefits held across the theoretical principles. This assignment will analyse and critically evaluate behaviourist and cognitivist theories in terms of learning and education; reflecting back on application to a classroom environment.

While both conceptions actually result in knowledge being gained, the means by which it is acquired are different. In order to fully understand how each of these behavior modification techniques can be used, it is important to have an appreciation of just how classical conditioning and operant conditioning are actually different from one another.

According to learning theory, addictions is basically a learned behavior. For example, people learn many of their addictive behaviors through what is called classical conditioning. Furthermore, people always pair up environmental cues with addictive substances. Fortunately, many addictions can be â€Å"unlearned† and we can do this by counter-conditioning. Counter –conditioning is a type of classical conditioning and we do this by doing something called taste aversionRead MorePsychology : The Learning Perspective Essay1882 Words   |  8 Pagesbroad subject filled with many different theories, several theories of which that were particularly interesting fall under the topic â€Å"The Learning Perspective†.
