Key Principles of Classical Conditioning Classical Conditioning Examples View All Back To Top Classical conditioning is a type of learning that had a major influence on the school of thought in psychology known as behaviorism. Discovered by Russian physiologist Ivan Pavlov, classical conditioning is a learning process that occurs through associations between an environmental stimulus and a naturally occurring stimulus.??? Illustration by Joshua Seong, Verywell Classical Conditioning Basics Although classical conditioning was not discovered by a psychologist at all, it had a tremendous influence over the school of thought in psychology known as behaviorism.??? Behaviorism is based on the assumption that:All  learning occurs through interactions with the environmentThe environment shapes behavior Its important to note that classical conditioning involves placing a neutral signal before a naturally occurring reflex. In Pavlovs classic experiment with dogs, the neutral signal was the sound of a tone and the naturally occurring reflex was salivating in response to food. By associating the neutral stimulus with the environmental stimulus (presenting of food), the sound of the tone alone could produce the salivation response.??? In order to understand how more about how classical conditioning works, it is important to be familiar with the basic principles of the process. How Does Classical Conditioning Work? Classical conditioning basically involves forming an association between two stimuli resulting in a learned response.??? There are three basic phases of this process: Phase 1: Before Conditioning The first part of the classical conditioning process requires a naturally occurring stimulus that will automatically elicit a response. Salivating in response to the smell of food is a good example of a naturally occurring stimulus. During this phase of the processes, the unconditioned stimulus (UCS) results in an unconditioned response (UCR).??? For example, presenting food (the UCS) naturally and automatically triggers a salivation response (the UCR). At this point, there is also a neutral stimulus that produces no effect - yet. It isnt until this neutral stimulus is paired with the UCS that it will come to evoke a response. Lets take a closer look at the two critical components of this phase of classical conditioning. The unconditioned stimulus is one that unconditionally, naturally, and automatically triggers a response.??? For example, when you smell one of your favorite foods, you may immediately feel very hungry. In this example, the smell of the food is the unconditioned stimulus. The unconditioned response is the unlearned response that occurs naturally in response to the unconditioned stimulus.??? In our example, the feeling of hunger in response to the smell of food is the unconditioned response. Phase 2: During Conditioning During the second phase of the classical conditioning process, the previously neutral stimulus is repeatedly paired with the unconditioned stimulus. As a result of this pairing, an association between the previously neutral stimulus and the UCS is formed. At this point, the once neutral stimulus becomes known as the conditioned stimulus (CS). The subject has now been conditioned to respond to this stimulus. The conditioned stimulus is previously neutral stimulus that, after becoming associated with the unconditioned stimulus, eventually comes to trigger a conditioned response.??? In our earlier example, suppose that when you smelled your favorite food, you also heard the sound of a whistle. While the whistle is unrelated to the smell of the food, if the sound of the whistle was paired multiple times with the smell, the sound would eventually trigger the conditioned response. In this case, the sound of the whistle is the conditioned stimulus. Phase 3: After Conditioning Once the association has been made between the UCS and the CS, presenting the conditioned stimulus alone will come to evoke a response even without the unconditioned stimulus. The resulting response is known as the conditioned response (CR).??? The conditioned response is the learned response to the previously neutral stimulus. In our example, the conditioned response would be feeling hungry when you heard the sound of the whistle. Key Principles of Classical Conditioning Behaviorists have described a number of different phenomena associated with  classical conditioning. Some of these elements involve the initial establishment of the response while others describe the disappearance of a response. These elements are important in understanding the classical conditioning process. Lets take a closer look at five key principles of classical conditioning: 1. Acquisition Acquisition  is the initial stage of learning when a response is first established and gradually strengthened.??? During the acquisition phase of classical conditioning, a neutral stimulus is repeatedly paired with an  unconditioned stimulus. As you may recall, an unconditioned stimulus is something that naturally and automatically triggers a response without any learning. After an association is made, the subject will begin to emit a behavior in response to the previously neutral stimulus, which is now known as a  conditioned stimulus. It is at this point that we can say that the response has been acquired. For example, imagine that you are conditioning a dog to salivate in response to the sound of a bell. You repeatedly pair the presentation of food with the sound of the bell. You can say the response has been acquired as soon as the dog begins to salivate in response to the bell tone. Once the response has been established, you can gradually reinforce the salivation response to make sure the behavior is well learned. Acquisition in Classical Conditioning 2. Extinction Extinction  is when the occurrences of a conditioned response decreases or disappears. In classical conditioning, this happens when a conditioned stimulus is no longer paired with an unconditioned stimulus.??? For example, if the smell of food (the unconditioned stimulus) had been paired with the sound of a whistle (the conditioned stimulus), it would eventually come to evoke the conditioned response of hunger. However, if the unconditioned stimulus (the smell of food) were no longer paired with the conditioned stimulus (the whistle), eventually the conditioned response (hunger) would disappear. Extinction in Classical Conditioning 3. Spontaneous Recovery Sometimes a learned response can suddenly reemerge even after a period of extinction.  Spontaneous recovery  is the reappearance of the conditioned response after a rest period or period of lessened response.??? For example, imagine that after training a dog to salivate to the sound of a bell, you stop reinforcing the behavior and the response eventually becomes extinct. After a rest period during which the conditioned stimulus is not presented, you suddenly ring the bell and the animal spontaneously recovers the previously learned response. If the conditioned stimulus and unconditioned stimulus are no longer associated, extinction will occur very rapidly after a spontaneous recovery. Why Spontaneous Recovery Is Important in Psychology 4. Stimulus Generalization Stimulus generalization  is the tendency for the conditioned stimulus to evoke similar responses after the response has been conditioned.??? For example, if a dog has been conditioned to salivate at the sound of a bell, the animal may also exhibit the same response to stimuli that are similar to the conditioned stimulus. In John B. Watsons famous  Little Albert Experiment, for example, a small child was conditioned to fear a white rat. The child demonstrated stimulus generalization by also exhibiting fear in response to other fuzzy white objects including stuffed toys and Watson own hair. How Stimulus Generalization Influences Learning 5. Stimulus Discrimination Discrimination  is the ability to differentiate between a conditioned stimulus and other stimuli that have not been paired with an unconditioned stimulus.??? For example, if a bell tone were the conditioned stimulus, discrimination would involve being able to tell the difference between the bell tone and other similar sounds. Because the subject is able to distinguish between these stimuli, he or she will only respond when the conditioned stimulus is presented. Understanding Stimulus Discrimination Classical Conditioning Examples It can be helpful to look at a few examples of how the classical conditioning process operates both in experimental and real-world  settings. Classical Conditioning of a Fear Response One of the most famous examples of classical conditioning was John B. Watsons experiment in which a fear response was conditioned in a boy known as Little Albert.??? The child initially showed no fear of a white rat, but after the rat was paired repeatedly with loud, scary sounds, the child would cry when the rat was present. The childs fear also generalized to other fuzzy white objects. Lets examine the elements of this classic experiment. Prior to the conditioning, the white rat was a neutral stimulus. The unconditioned stimulus was the loud, clanging sounds and the unconditioned response was the fear response created by the noise. By repeatedly pairing the rat with the unconditioned stimulus, the white rat (now the conditioned stimulus) came to evoke the fear response (now the conditioned response). This experiment illustrates how phobias can form through classical conditioning. In many cases, a single pairing of a neutral stimulus (a dog, for example) and a frightening experience (being bitten by the dog) can lead to a lasting phobia (being afraid of dogs). Classical Conditioning of Taste Aversions Another example of classical conditioning can be seen in the development of conditioned taste aversions. Researchers John Garcia and Bob Koelling first noticed this phenomenon when they observed how rats that had been exposed to a nausea-causing radiation developed an aversion to flavored water after the radiation and the water were presented together.??? In this example, the radiation represents the unconditioned stimulus and the nausea represents the unconditioned response. After the pairing of the two, the flavored water is the conditioned stimulus, while the nausea that formed when exposed to the water alone is the conditioned response. Later research demonstrated that such classically conditioned aversions could be produced through a single pairing of the conditioned stimulus and the unconditioned stimulus. Researchers also found that such aversions can even develop if the conditioned stimulus (the taste of the food) is presented several hours before the unconditioned stimulus (the nausea-causing stimulus).??? Why do such associations develop so quickly? Obviously, forming such associations can have survival benefits for the organism. If an animal eats something that makes it ill, it needs to avoid eating the same food in the future to avoid sickness or even death. This is a great example of what is known as biological preparedness. Some associations form more readily because they aid in survival.??? In one famous field study, researchers injected sheep carcasses with a poison that would make coyotes sick but not kill them. The goal was to help sheep ranchers reduce the number of sheep lost to coyote killings. Not only did the experiment work by lowering the number of sheep killed, it also caused some of the coyotes to develop such a strong aversion to sheep that they would actually run away at the scent or sight of a sheep. A Word From Verywell In reality, people do not respond exactly like Pavlovs dogs. There are, however, numerous real-world applications for classical conditioning. For example, many dog trainers use classical conditioning techniques to help people train their pets. These techniques are also useful for helping people cope with phobias or anxiety problems. Therapists might, for example, repeatedly pair something that provokes anxiety with relaxation techniques in order to create an association. Teachers are able to apply classical conditioning in the class by creating a positive classroom environment to help students overcome anxiety or fear. Pairing an anxiety-provoking situation, such as performing in front of a group, with pleasant surroundings helps the student learn new associations. Instead of feeling anxious and tense in these situations, the child will learn to stay relaxed and calm.

Definition and History of the Sapir-Whorf Hypothesis

The Sapir-Whorf hypothesis is the  linguistic theory that the semantic structure of a language shapes or limits the ways in which a speaker forms conceptions of the world. It came about in 1929. The theory is named after the American anthropological linguist Edward Sapir (1884–1939) and his student Benjamin Whorf (1897–1941). It is also known as the  theory of linguistic relativity, linguistic relativism, linguistic determinism, Whorfian hypothesis, and Whorfianism. History of the Theory The idea that a persons native language determines how he or she thinks was popular among behaviorists of the 1930s and on until cognitive psychology theories came about, beginning in the 1950s and increasing in influence in the 1960s. (Behaviorism taught that behavior is a result of external conditioning and doesnt take feelings, emotions, and thoughts into account as affecting behavior. Cognitive psychology studies mental processes such as creative thinking, problem-solving, and attention.) Author Lera Boroditsky gave some background on ideas about the connections between languages and thought: The question of whether languages shape the way we think goes back centuries; Charlemagne proclaimed that to have a second language is to have a second soul. But the idea went out of favor with scientists when  Noam Chomskys theories of language gained popularity in the 1960s and 70s. Dr. Chomsky proposed that there is a  universal grammar  for all human languages—essentially, that languages dont really differ from one another in significant ways....  (Lost in Translation. The Wall Street Journal, July 30, 2010) The Sapir-Whorf hypothesis was taught in courses through the early 1970s and had become widely accepted as truth, but then it fell out of favor. By the 1990s, the Sapir-Whorf hypothesis was left for dead, author Steven Pinker wrote. The cognitive revolution in psychology, which made the study of pure thought possible, and a number of studies showing meager effects of language on concepts, appeared to kill the concept in the 1990s... But recently it has been resurrected, and neo-Whorfianism is now an active research topic in  psycholinguistics. (The Stuff of Thought. Viking, 2007) Neo-Whorfianism is essentially a weaker version of the Sapir-Whorf hypothesis and says that language  influences  a speakers view of the world but does not inescapably determine it. The Theorys Flaws One big problem with the original Sapir-Whorf hypothesis stems from the idea that if a persons language has no word for a particular concept, then that person would not be able to understand that concept, which is untrue.  Language doesnt necessarily control humans ability to reason or have an emotional response to something or some idea. For example, take the German word  sturmfrei, which essentially is the feeling when you have the whole house to yourself because your parents or roommates are away. Just because English doesnt have a single word for the idea doesnt mean that Americans cant understand the concept. Theres also the chicken and egg problem with the theory. Languages, of course, are human creations, tools we invent and hone to suit our needs,  Boroditsky continued. Simply showing that speakers of different languages think differently doesnt tell us whether its language that shapes thought or the other way around.

High School Dropouts And Its Effect On Our Country

According to Americangraduatedc.org, 1.3 million students each year dropout of high school in the United States alone. Dropouts refers to a student quitting school before he or she graduates or avoiding enrolling in college. Students who drop out are more likely to be unemployed, homeless, or receiving welfare. High School dropouts are very common in the United States today. Only 72% of America s children graduate from high school.

Not another romantic movie essays

Not another romantic movie essays Whether we admit it or not, we know that deep, down in each one of us, there exists a hopeless romantic. People long to experience love; experience how to love and how it feels to be loved. Sometimes, we experience this love by watching romantic films. We are thrilled to get a view of beautiful leading ladies and dashing leading men, wishing we were the characters that they portrayed. We usually want to witness them experience a happy ending just as we want ourselves to experience the same. But then, sometimes we feel that we have seen enough of these very predictable, unrealistic romantic films and realize we want something new. Well, we might have just found an original, intelligent and realistic romantic film about fate and destiny in the movie Before Sunset. It had a refreshingly unique story, convincing actors and a romantic setting. This movie proves to be different from many other romantic films. Unlike other films where a lot of kissing and intimate scenes are needed to portray the romance between the leading characters, in this movie, their conversations alone were already romantic and engrossing. It was a great plus for this movie for it had insightful conversations between the main characters. A downside to the uniqueness of this movie is that some people still prefer the old typical romantic movies. Some people might look for the intimate scenes and get bored with the seemingly endless conversation between the two characters. Yet, the distinctiveness of this film is intriguing enough to make the viewers hang on and await for every scene. Another thing, in most stories, destiny and fate brings the main characters together and is responsible for their happiness. Well in this film, destiny was accountable for causing Jesse and Celine pain. For instance, the scene where Jesse mentioned that on the day he was about to get married, he thought he saw Celine folding an umbrella across the street and later on learned f...

Glossary of Common Mitosis Terms

Glossary of Common Mitosis Terms Mitosis Glossary Mitosis is a form of cell division that enables organisms to grow and reproduce. The mitosis stage of the cell cycle involves the separation of nuclear chromosomes, followed by cytokinesis (division of the cytoplasm forming two distinct cells). At the end of mitosis, two distinct daughter cells are produced. Each cell contains identical genetic material. This Mitosis Glossary is a good resource for finding succinct, practical, and meaningful definitions for common mitosis terms. Mitosis Glossary - Index Anaphase - stage in mitosis where chromosomes begin moving to opposite ends (poles) of the cell. Allele - an alternative form of a gene (one member of a pair) that is located at a specific position on a specific chromosome. Asters - radial microtubule arrays found in animal cells that help to manipulate chromosomes during cell division. Cell Cycle - the life cycle of a dividing cell. It includes Interphase and the M phase or Mitotic phase (mitosis and cytokinesis). Centrioles - cylindrical structures that are composed of groupings of microtubules arranged in a 9 3 pattern. Centromere - a region on a chromosome that joins two sister chromatids. Chromatid - one of two identical copies of a replicated chromosome. Chromatin - mass of genetic material composed of DNA and proteins that condense to form chromosomes during eukaryotic cell division. Chromosome - a long, stringy aggregate of genes that carries heredity information (DNA) and is formed from condensed chromatin. Cytokinesis - d ivision of the cytoplasm that produces distinct daughter cells. Cytoskeleton - a network of fibers throughout the cells cytoplasm that helps the cell maintain its shape and gives support to the cell. Daughter Cell - a cell resulting from the replication and division of a single parent cell. Daughter Chromosome - a chromosome that results from the separation of sister chromatids during cell division. Diploid Cell - a cell that contains two sets of chromosomes. One set of chromosomes is donated from each parent. Genes - segments of DNA located on chromosomes that exist in alternative forms called alleles. Haploid Cell - a cell that contains one complete set of chromosomes. Kinetochore - a specialized region on the centromere of chromosome where spindle polar fibers attach to the chromosome. Kinetochore Fibers - microtubules that connect kinetochores to spindle polar fibers. Interphase - stage in the cell cycle where a cell doubles in size and synthesizes DNA in preparation for cell division. Metaphase - stage in mitosis where chromosomes align alo ng the metaphase plate in the center of the cell. Microtubules - fibrous, hollow rods, that function primarily to help support and shape the cell. Mitosis - a phase of the cell cycle that involves the separation of nuclear chromosomes followed by cytokinesis. Nucleus - a membrane-bound structure that contains the cells hereditary information and controls the cells growth and reproduction. Polar Fibers - spindle fibers that extend from the two poles of a dividing cell. Prophase - stage in mitosis where chromatin condenses into discrete chromosomes. Sister Chromatids - two identical copies of a single chromosome that are connected by a centromere. Spindle Fibers - aggregates of microtubules that move chromosomes during cell division. Telophase - stage in mitosis where the nucleus of one cell is divided equally into two nuclei.
