Who Was Ivan Pavlov Psychology And The Impact Of Classical Conditioning
Some of the earliest clinical researchers have paved the way for much about what we know today about how the brain and other bodily functions react to stimuli. Such groundbreaking discoveries have led to important treatments that have improved the health and well-being of countless individuals today. Ivan Pavlov was an early physiologist who devoted his career to advancing science in the area of digestive secretions.
His meager roots and staunch religious upbringing played a strong role in forming the man he eventually became in his personal life and his approach to his work in the laboratory. Like many of the greatest clinical researchers of all time, Pavlov had an insatiable curiosity and a willingness to innovate and experiment in ways that had never be done and never will be done again.
Who Was Ivan Pavlov?
Ivan Petrovich Pavlov was born in 1840 in Ryazan, in central Russia. He was a Russian physiologist who is famous for developing the concept of a conditioned reflex. Pavlov mastered his philosophy by proving that animals could be conditioned to respond to various stimuli. He was rewarded handsomely for his work when, in 1904, he was awarded the Nobel Prize for Physiology or Medicine for his research on digestive secretions. He was the very first Russian Nobel laureate.
Family And Early Life Of Ivan Pavlov
While Pavlov ultimately declared himself to be an atheist, he attributed much of his success to Sara, who was very religious.
Pavlov’s Schooling
Discovery Of Classical Conditioning
While researching the digestive function of dogs, he noted his subjects would salivate before the delivery of food. In a series of well-known experiments, he presented a variety of stimuli before the presentation of food, eventually finding that, after repeated association, a dog would salivate to the presence of a stimulus other than food.
Pavlov termed this response a conditional reflex. Pavlov also discovered that these reflexes originate in the cerebral cortex of the brain.
Pavlov received considerable acclaim for his work, including a 1901 appointment to the Russian Academy of Sciences and the 1904 Nobel Prize in Physiology. The Soviet government also offered substantial support for Pavlov’s work, and the Soviet Union soon became a leading center of physiology research.
He died on February 27, 1936.
Classical Conditioning Of The Eyeblink Response
Whereas Ivan Pavlov discovered the phenomenon of classical conditioning using a conditioned reflex in the autonomic nervous system, the conditioned reflexes used in contemporary studies of classical conditioning, such as the conditioned eyeblink response, are controlled in the central nervous system. Skeletal muscle innervated by the cranial nerves controls the eyeblink. Eyeblink classical conditioning is a common paradigm for investigations of classical conditioning in general and classical conditioning in normal aging in particular. Fear conditioning, in which a neutral CS is paired with a moderately painful US, is another promising model system that has been elaborated extensively on a behavioral and neurobiological level. Studies of aging effects on fear conditioning have been reported, but the results are not consistent. The magnitude of age-related fear responses appears to be small, especially in comparison with age-related changes in eyeblink classical conditioning.
The neural circuitry that supports classical conditioning of the eyeblink response is almost completely mapped, and the behavioral and neurobiological parallels in this form of associative learning extend to all mammals that have been studied, including humans. Processes of normal aging affect eyeblink classical conditioning similarly in all species in which older organisms have been tested mice, rats, rabbits, cats, and humans.

- It shows how scientific research proceeds, because Pavlov brought physiology together with psychology . He also showed how the Learning Approach and the Biological Approach cross over.
- It illustrates the usefulness of the observational method, especially controlled observations in artificial conditions
- However, it raises important methodological issues about drawing conclusions from animal research and the low ecological validity of artificial situations
What Did Ivan Pavlov Study
Ivan Pavlov gave up studying theology to enter the University of St. Petersburg, where he studied chemistry and physiology. After receiving an M.D. at the Imperial Medical Academy in St. Petersburg, he studied in Germany under the direction of the cardiovascular physiologist Carl Ludwig and the gastrointestinal physiologist Rudolf Heidenhain.

Ivan Pavlovs Contribution To Psychology
Ivan Pavlov was a Russian psychologist born on September 26, 1849, and died on February 27, 1936. While other famous psychologists didnt always have a passion for education and learning, Pavlov prioritized knowledge his whole life. From a young age, he understood the importance of gathering and understanding new information. However, Pavlovs area of study was not psychology but physiology.
Physiology focuses on understanding how the body works.
Pavlov was mentored by some of the top professors and physiologists of the day during his schooling in physiology. Pavlov was so successful during his education that he won countless prizes within his departments. Eventually, Pavlov finished his doctorate. He researched at different German labs but ultimately returned to his home country. After Pavlov returned to Russia, he spent most of his time studying digestion which won him a Nobel Prize in Physiology or Medicine in 1904!

Condition Stimulus And Condition Response
In Pavlovs famous experiment when the dogs found the association between hearing the bell sound and the food, he called the bell conditioned stimulus because the signal served as a stimulation for behavior and he called the salivation a conditioned response because the salivated was the dogs response to the sound of the bell. It was determined that not only do dogs respond to stimuli in this way, but humans do, too. Pavlovs discovery of conditioned stimulus conditioned response, and spontaneous recovery taught us a lot about how our brains affiliate things with one another and how we can train our minds using this knowledge about how conditioning works. One common example of how we can implement this in our daily lives is in reward-punishment systems used by both children and adults. For instance, if a parent provides a child with a toy or sticker when they behave well, the child will be conditioned to affiliate good behavior with receiving a reward.

Making Of A Physiologist
In 1870 Pavlov gained admission to the University of St. Petersburg , electing animal physiology as his major field and chemistry as his minor. There he studied inorganic chemistry under Dmitrii Mendeleev and organic chemistry under Aleksandr Butlerov, but the deepest impression was made by the lectures and the skilled experimental techniques of Ilya Tsion. It was in Tsion’s laboratory that Pavlov was exposed to scientific investigations, resultingin his paper “On the Nerves Controlling the Pancreatic Gland.”
After graduating, Pavlov entered the third course of the Medico-Chirurgical Academy , working as a laboratory assistant . In 1877 he published his first work, Experimental Data Concerning the Accommodating Mechanism of the Blood Vessels, dealing with the reflex regulation of the circulation of blood. Two years later he completed his course at the academy, and on the basis of a competitive examination he was awarded a scholarship for postgraduate study at the academy.
Pavlov spent the next decade in Sergei Botkins laboratory at the academy. In 1883 Pavlov completed his thesis, The Centrifugal Nerves of the Heart, and received the degree of doctor of medicine. The following year he was appointed lecturer in physiology at the academy, won the Wylie fellowship, and then spent the next 2 years in Germany. During the 1880s Pavlov perfected his experimental techniques which made possible his later important discoveries.
Nobel Prize And Achievements
For his groundbreaking work, Pavlov was named the 1904 Nobel Prize winner for Physiology or Medicine. More honors followed over the years. He was elected Academician of the Russian Academy of Sciences in 1907, and in 1912 he was given an honorary doctorate at Cambridge University. Following a recommendation by the Medical Academy of Paris, he was awarded the Order of the Legion of Honour in 1915.

Personal Life And Marriage
Ivan Pavlov married Seraphima Vasilievna Karchevskaya in 1881. Together, they had five children: Wirchik, Vladimir, Victor, Vsevolod, and Vera. In their early years, Pavlov and his wife lived in poverty. During the hard times, they stayed with friends, and at one point, rented a bug-infested attic space.
Pavlov’s fortunes changed in 1890 when he took an appointment as the Professor of Pharmacology at the Military Medical Academy. That same year, he became the director of the Department of Physiology at the Institute of Experimental Medicine. With these well-funded academic positions, Pavlov had the opportunity to further pursue the scientific studies that interested him.

Ivan Pavlov, in full Ivan Petrovich Pavlov, , Russian physiologist known chiefly for his development of the concept of the conditioned reflex. In a now-classic experiment, he trained a hungry dog to salivate at the sound of a metronome or buzzer, which was previously associated with the sight of food. He developed a similar conceptual approach, emphasizing the importance of conditioning, in his pioneering studies relating human behaviour to the nervous system. He was awarded the Nobel Prize for Physiology or Medicine in 1904 for his work on digestive secretions.

How Pavlov Contributed To The Psychology Field
Pavlov was not a psychologist, and in fact, he disliked psychology, but his work had a supreme impact on the field. His work influenced behaviorism. One of the earliest published works by Pavlov was the work of the digestive glands, and that was centered around his physiology research with dogs. He didnt intend to influence the world of psychology, but with his work regarding classical conditioning, great strides were made in the field.
Pavlovs Dogs Study And Pavlovian Conditioning Explained
By Dr. Saul McLeod, updated 2021
Like many great scientific advances, Pavlovian conditioning was discovered accidentally. Ivan Petrovich Pavlov was aphysiologist, not a psychologist.
During the 1890s, Russian physiologist, Ivan Pavlov was researching salivation in dogs in response to being fed. He inserted a small test tube into the cheek of each dog to measure saliva when the dogs were fed .
Pavlov predicted the dogs would salivate in response to the food placed in front of them, but he noticed that his dogs would begin to salivate whenever they heard the footsteps of his assistant who was bringing them the food.
When Pavlov discovered that any object or event which the dogs learned to associate with food would trigger the same response, he realized that he had made an important scientific discovery. Accordingly, he devoted the rest of his career to studying this type of learning.

How Did Pavlovs Dog Experiments Work
So Pavlov started to play the tone before he fed his dogs. He repeated the process for days. After some time had passed, he played the tone without presenting any food to the dogs. As he expected, his dogs showed an increase in salivation whenever they heard the tone.
Although the dogs had no response to the tone at the start of the experiment, they had learned a new response by the end of it. And as this response needed to be learned, Pavlov called it a conditional reflex. Pavlov also recognized that the tone was no longer a neutral stimulus. By linking it with food , the tone had become a conditioned stimulus.
There are many reports that Pavlov used a bell for the experiments he conducted with his dogs. And he may have used one on occasion. However, Pavlov wanted to control the intensity, quality, and duration of the stimuli. So he relied heavily on a metronome, harmonium, buzzer, and even electric shocks for most of his experiments.
There was one more thing Pavlov discovered during his experiment. He realized that the tone and the food needed to be presented close together in time for the link to be made. He referred to this requirement as the law of temporal contiguity. If there is too much time between the playing of the tone and the presentation of the food, the dogs would not learn to salivate when they heard the tone.
Ivan Pavlov Theory: Classical Conditioning
First discovered by Russian physiologist Ivan Pavlov , classical conditioning is a learning process governed by associations between an environmental stimulus and another stimulus which occurs naturally.
All classical conditioned learning involves environmental interaction. For learning to occur, there must also be a neutral stimulus which is then followed by a naturally occurring reflex. For instance, Pavlovs dogs heard a tone followed by salivating in response to the arrival of food. Once the sound of the neutral stimulus became linked to the stimulus present in the environment , it soon became possible to induce salivating just by sounding the neutral stimulus.
The action of classical conditioning upon a subject is a three-phase process:

Ivan Pavlovs Dogs: The Discovery Of Classical Conditioning
Ivan Pavlov was a Russian physiologist who is most famous for his discovery of classical conditioning. Classical conditioning occurs when a previously neutral stimulus is paired with a stimulus that elicits a reflexive response . After repeated pairings, the neutral stimulus comes to elicit the reflexive response on its own. Ivan Pavlovs dogs study pioneered discoveries in classical conditioning.
In one of his experiments, Pavlov would ring a bell before he gave the dogs food. Over time, the sound of the bell would make the Ivan Pavlovs dogs salivate, even when there was no food present. This is because the sound of the bell had become associated with the taste of food, and it elicited a reflexive response in the dogs.
Pavlovs experiments with dogs helped to establish classical conditioning as a scientific principle, and they have been used to study everything from human learning and behavior to drug addiction. Classical conditioning is now considered to be one of the most basic forms of learning.
Pavlovs discovery of classical conditioning has had a lasting impact on the field of psychology, and his work remains relevant today. In fact, classical conditioning is still being used to study everything from human behavior to drug addiction. Thanks to Ivan Pavlov, we now have a better understanding of how learning works, and how it can be applied in different settings.

Early Years And Education
Pavlov was born on September 14, 1849, in the small village of Ryazan, Russia. His father, Peter Dmitrievich Pavlov, was a priest who hoped that his son would follow in his footsteps and join the church. In Ivan’s early years, it seemed that his father’s dream would become a reality. Ivan was educated at a church school and a theological seminary. But when he read the works of scientists like Charles Darwin and I. M. Sechenov, Ivan decided to pursue scientific studies instead.
He left the seminary and began studying chemistry and physiology at the University of St. Petersburg. In 1875, he earned an M.D. from the Imperial Medical Academy before going on to study under Rudolf Heidenhain and Carl Ludwig, two renowned physiologists.

Ivan Pavlov Children And Wife
Ivan Pavlov met Seraphima Vasilievna Karchevskaya in 1878 or 1879. At the time, Sara was a student at the Pedagogical Institute. It did not take long for the young couple to fall in love. They were married on May 1, 1881.
When Sara became pregnant for the first time, she had a miscarriage. The couple was very careful the second time Sara conceived, and she gave birth to a healthy baby boy named Mirchik. However, Mirchik died suddenly in childhood and this made Sara very depressed. Eventually, the couple had four more children. Their names were Vladimir, Victor, Vsevolod, and Vera.
Ivan and Sara Pavlov spent their first nine years as husband and wife in poverty. Due to their financial troubles, they were often forced to live in different homes so they could benefit from the hospitality of other people. Pavlov even grew potatoes and other crops outside his lab to help make ends meet. Once their finances became stable, Ivan and Sara were able to live together in the same house.
Pavlov was eventually able to earn money from health products he made in his lab. He sold the gastric juice he collected from his dogs as an effective treatment for indigestion. Of course, winning the Nobel Prize in 1904 brought monetary rewards. However, the ever-changing political scene in Russia made life difficult for him, his family, and his fellow scientists.
