Ivan pavlov theory
The learning theory that evolved from Pavlov's findings on conditioned reflexes became known as classical conditioning. Conditioning helps to explain the ways in which some people develop seemingly irrational fears and anxieties or associate certain smells and sounds with a specific place or situation. The theory even discusses why a dog barks and becomes agitated when the doorbell rings.
Through his work on the nervous system and cerebral cortex , Pavlov also was one of the first scientists to explore the role of personality and temperament in physiological reactions. Despite well-controlled conditions and precise measurements, not all dogs would react exactly the same to an identical stimulus, even when allowances were made for different physical characteristics.
Furthermore, Pavlov discovered that certain temperament types were more prone to psychopathological conditions than others. Pavlov conducted extensive experimentation that involved removing portions of the brains of dogs to establish that the cerebral cortex was related to reflexive reactions. Pavlov believed that all of what was considered "psychic" phenomenon, which had previously been explained only in terms of abstract introspective processes such as psychoanalysis, could be explained through careful physiological experimentation.
In his Nobel lecture, Pavlov stated the scope of his vision:. Essentially only one thing in life interests us: our psychical constitution, the mechanism of which was and is wrapped in darkness. All human resources, art, religion, literature, philosophy and historical sciences, all of them join in bringing light in this darkness. But man has still another powerful resource: natural science with its strictly objective methods.
Main points Through Pavlov's work on the physiology of the digestive system, he discovered that digestive processes could be triggered even before food passed a dog's lips. Just showing food to a hungry dog could cause the animal to begin to salivate and secrete gastric juices. Why did these external factors cause these reactions, or reflexes?
The dogs had previously learned through experience that the appearance of a bowl of kibble meant they would be eating shortly, so the sight of food cued their digestive systems to start up. This finding was Pavlov's first indication that what he called "psychic" influences i. Pavlov had already demonstrated that the taste of food in a dog's mouth stimulated the animal's oral nerves in such a way that salivation was triggered, an involuntary physiological reaction he called an unconditioned response.
But Pavlov and his colleagues soon discovered that by repeatedly presenting a completely unrelated and neutral stimulus e. Pavlov called this reaction a conditioned response, or reflex, and the process by which it was achieved was called conditioning. Explanation In his Nobel lecture, Pavlov explained his theory of unconditioned or physiological and conditioned or psychic reflexes:.
The difference between the two reflexes is firstly that our old physiological reflex is constant, unconditioned, while the new reflex continually fluctuates and, hence, is conditioned. In other words, conditioning involves pairing a neutral stimulus or conditioned stimulus with an unconditioned stimulus to create a conditioned response.
Dogs that were exposed to a particular sound the conditioned stimulus each time they were given food the unconditioned stimulus eventually began to associate the bell with eating and would salivate at the sound of the bell. A conditioned reflex had been created in those dogs. Does a conditioned reflex occur every time a neutral stimulus is presented with an unconditioned stimulus?
Usually, the pairing must be repeated several times before conditioning takes hold; the number of repetitions depends upon the subject and the stimuli. A profound event or a very novel stimulus may require fewer pairings also called trials. The conditioned response is dependent on the intensity of the stimulus itself.
An American psychologist who founded the field of psychology known as behaviorism, John Broadus Watson — believed that psychological study should be based on observable reflexes and behavior only instead of introspection of the subconscious mind. Watson entered college at the age of 16, and received his Ph.
His dissertation involved work with learning behaviors culled from maze experiments with white rats. In he joined Johns Hopkins University, where he was appointed a professor and made director of the psychological laboratory. This work was followed a year later by his text Behaviorism: An Introduction to Comparative Psychology, which built on Pavlov's conditioned reflexes and outlined Watson's stimulus-response theory of behavior.
Watson was elected president of the American Psychological Association in at the age of 36, making him the youngest person ever to hold that office. Around this time, his research focus shifted to infants and children. Watson believed that all human emotion was rooted in three reactions—fear, rage, and love—that were not innate but rather conditioned.
Through a now infamous experiment with a white rat and an month-old boy named "Little Albert," Watson conditioned the boy to be afraid of a white rat by banging on a metal bar loudly with a hammer and frightening him each time he reached for the animal. Albert quickly became fearful at the sight of the rat alone.
Later, he discovered that Albert subsequently transferred this fear-response reaction to another stimulus, also becoming afraid of a white rabbit with which he had previously played. This phenomenon of developing a conditioned response to a stimulus that is different from but similar to the original stimulus used in conditioning came to be known as generalization.
His distinguished career in academia came a sudden end in after a scandal involving an affair with a research assistant. Watson subsequently divorced his wife and married graduate student Rosalie Rayner, and he was asked to resign his professorship at Johns Hopkins. By , Watson had become a vice president at J. Walter Thompson, one of America's largest ad agencies, where he remained until Here he helped develop and refine a number of groundbreaking strategies that persist in the field today, including market research of the motivations behind consumer brand loyalty and testimonial advertising.
Watson continued to write on behavioral psychology, making the field more accessible to the general public. He participated in applied psychology projects while working in the ad world; for example, he was one of the first proponents of personality testing for prospective employees in the corporate world. Watson wrote a popular book entitled Psychological Care of the Infant that was based on his observational studies of infants and his theories of behavioral psychology.
He believed that proper conditioning of the child was the key to forming healthy personality traits. In , Watson left J. Walter Thompson to continue his advertising career at the William Esty Company, where he remained until his retirement in The APA awarded Watson a gold medal for his contributions to psychology in One year later, he passed away at the age of A unique or novel neutral stimulus is more likely to cause a conditioned response than a common one.
For example, a woman who split up with her boyfriend while a certain song was playing on the radio may forever identify that particular tune with heartache. But if a telephone was also ringing at the same time, the less "novel" stimulus of a ringing phone would be less likely to trigger an emotional response in the future.
Finally, Pavlov believed that the neutral stimulus had to be contiguous that is, occur at the same time or in close proximity to the unconditioned stimulus in order for a conditioned response to develop. Later research has found that conditioning is most effective when the conditioned stimulus is presented just before the unconditioned stimulus, and when both stop at the same time.
Pavlov discovered that conditioned reflexes could be reversed if the neutral stimulus was presented enough times in the absence of the unconditioned stimulus. He explains the process, known as extinction, in the context of his study on salivating dogs and food: "On the other hand promptly active signals can lose their stimulating effect if repeated over a long period without bringing the object concerned into contact with the oral mucous membrane.
Extinction of a behavior was not always permanent, however. Pavlov found that conditioned responses that were extinguished could spontaneously recur later spontaneous recovery. One of Pavlov's dogs had been conditioned to salivate at the sound of a bell.

Pavlov extinguished the reflex by repeatedly exposing the dog to the bell without the presence of food or feeding. Although the conditioned reflex was gone, Pavlov found that some time later, it suddenly reappeared when the dog was exposed to the sound of a bell. The response was weaker less salivation , but it was still present.
Conditioned reflexes could also be temporarily interrupted if extra stimuli were introduced, either on purpose or unintentionally. In Conditioned Reflexes, Pavlov described how a co-worker would call him into their work area to demonstrate a dog's newly acquired conditioned reflex, only to have the dog fail to perform. The reason was Pavlov's presence itself; he was what he termed a temporary inhibitory stimulus; his presence triggered the dog's investigatory reflex and temporarily distracted it what one might call a sense of curiosity, although Pavlov did not like to attribute human characteristics to his dogs.
Pavlov also developed the concept of higher-order conditioning, which involved pairing one neutral stimulus previously associated with a conditioned response with a second neutral stimulus. In higher-order, or second-order conditioning, a conditioned stimulus A is first paired with an unconditioned stimulus until a conditioned response is achieved.
Then a second conditioned stimulus B is paired with the first conditioned stimulus A. Even though the unconditioned stimulus is never presented with stimulus B, it is able to achieve a conditioned response simply by its association with the stimulus A. Examples Pavlov's drooling dogs are the most famous example of classical conditioning.
A bell is rung immediately before or as food is served to a dog. With repetition, the dog eventually salivates at the sound of the bell only. Pavlov used a number of different neutral stimuli in his conditioning experiments, including the beat of a metronome, flashes of light, odors, and skin stimulation. When the bell was rung repeatedly without the presence of food or feeding of the dogs , the conditioned response would eventually disappear.
Many dogs will also show a classically conditioned response to the sound of a doorbell. The dog knows that the sound of the bell means a visitor has arrived, because the sound of the bell has preceded a guest's presence many times before. So when the doorbell rings, the dog runs to the door, wags his tail, and perhaps even barks in response, even though he cannot see who or what is on the other side.
In fact, even if the interior bell is located far from the front door, the dog will still run to the door because he knows from experience the visitor will appear here. If someone plays ding-dong-ditch rings the doorbell and runs away before the resident anwers the door a few times, however, the dog may get a little less excited about the sound of the bell.
And some dogs may also react to the sound of the phone, because they have generalized their conditioned response to the doorbell stimulus to apply to similar stimuli in this case, all bells. For more on generalization, see "John Watson" sidebar. The influence of classical conditioning is quite commonly seen in house pets.
Any cat owner knows that the sound of a can opener will trigger a feline frenzy. Because the owner has conditioned the cat to associate the sound of a can being opened with dinnertime. For humans, conditioning can often be seen as phobias and irrational fears. Prior bad experiences associated with places, people, activities, or things can condition individuals to develop fearful or anxious reactions to neutral events or objects.
For example:. Pavlov believed that the theory of classical conditioning could help eradicate neuroses and psychoses as well as explain their origins. Main points For Pavlov, temperament of both animals and humans is determined by the interplay of what he called excitatory and inhibitory responses. As the names suggest, excitation stimulates nervous reaction while inhibition suppresses it.
Through his studies of the nervous system of dogs, Pavlov developed the theory that abnormalities in behavior and temperament occur when excitation and inhibition are either out of balance or when both processes are very weak. Dogs that had strong excitatory and inhibitory responses that were in equilibrium were the most easily disciplined; those dogs also responded the best to conditioning.
Pavlov called their temperament type strong. In those animals for which both excitation and inhibition were weak or were out of balance with each other, behavioral problems and neuroses were common. Pavlov found that these dogs were not able to deal appropriately with environmental stimuli. Pavlov called this type of dog inhibitable, or weak. An animal's ability to adapt quickly to a changing environment, called mobility, also influenced its temperament type.
Pavlov's theory of temperament types was rooted in the ancient concept made famous by the Greek physician Galen of four humors: choleric, melancholic, sanguine, and phlegmatic. The Greeks believed that the balance of the four humors which corresponded to yellow bile, black bile, blood, and phlegm determined an individual's personality type.
The relative quantities of the humors created warm versus cool and dry versus moist which were related to the elements of fire, air, earth, and water. A person with an excess of yellow bile was choleric warm and dry—also easily excitable and hot-tempered , one with an abundance of black bile was melancholic cool and dry—also inhibited and pessimistic , someone with excess blood was sanguine warm and moist—also confident and energetic , and finally, one with abundant phlegm was phlegmatic cool and moist—also calm and hard-working.
In Pavlov's system, the choleric temperament is analogous to the excitable type, the melancholic to the inhibitable type, and the phlegmatic and sanguine to the strong type. Of course, Pavlov realized that the human personality was slightly more complex than the personalities of the dogs he studied. He believed human behavior was determined by three factors:.
The first signal system is conditioned reflexes—instinctual behaviors learned through experience with one's environment. Pavlov also realized that, unlike his dogs, human beings also had a second set of signals at their disposal—language—or what Pavlov called "the signals of signals. Those who reacted predominately to environmental stimuli rather than language were called artists, while those for whom language was a greater motivator were termed thinkers.
Rarely, someone would have equal strength in both areas; Pavlov called these people "intermediate" types. Furthermore, Pavlov believed that the different personality types were prone to certain psychological disorders based on their reaction to their environment. Thinking types were predisposed to obsessions and phobias, while artistic types leaned towards hysteria and outbursts.
Whether or not these disorders manifested themselves depended on an individual's ability to cope with environmental stress or trauma. Explanation Pavlov found that neuroses could actually be induced in the lab in those animals with weak and unbalanced temperaments. Strong negative stimuli could cause experimental neuroses by overwhelming the animals' inhibitory or excitatory processes.
Stimuli that were difficult to differentiate from previously introduced stimuli could also cause behavioral problems. Neurotic behaviors might be removed through counter-conditioning techniques or by extinction of the conditioned response. Pavlov also experimented with the use of bromide drugs to return dogs to a non-neurotic state.
Pavlov's physiological experiments on the brain function of his animal subjects also influenced his theories on personality and psychopathology. He held that the basic drives, emotions, and instinctual behavior, or unconditioned reflexes, were regulated in the subcortex area of the brain in both animals and human beings.
Immediately above the subcortex, in the cerebral hemispheres, Pavlov believed could be found the "signal systems" that helped regulate temperament and subsequently behavior. He associated the first signal system conditioned reflexes with the cerebral hemispheres excluding the frontal lobes and the second signal system language with the frontal lobes.
In a work entitled "Essay on the Physiological Concept of the Symptomatology of Hysteria," Pavlov describes how the activity that takes place in each of these brain areas determines the temperament type of the individual:. In the artist the activity of the cerebral hemispheres, while developing throughout their entire mass, least of all involves the frontal lobes and concentrates mainly in other parts; in the thinker, on the contrary, it is most intense in the frontal lobes.
Pavlov had a special research interest in schizophrenia, and he studied many patients with the disorder at the Leningrad Clinic. He theorized that schizophrenia was the result of both a weak temperament type and childhood trauma. Because of schizophrenics' weak inhibitory responses, the trauma overwhelms them and damages their nervous system.
Examples One of Pavlov's students, N. Shenger-Krestovnikova, was the first researcher to describe the role of sensory discrimination in producing neuroses. Shenger-Krestovnikova performed an experiment that conditioned a dog to salivate whenever it saw a light projection of a circle that is, a visual image of a circle was paired with food.
At the same time, the dog was conditioned to have an inhibitory response when it was presented with an ellipse that is, the sight of an ellipse was followed by no food. Then Shenger-Krestovnikova gradually changed the shape of the ellipse to become more circular. Eventually, the dog could not discriminate the circle from the ellipse, and it lost all conditioned responses to both circles and ellipses.
The dog also demonstrated behavioral problems, such as whining and struggling, when presented with the task. Pavlov believed that the neurotic behavior in the dog was produced by a clash between the inhibition and excitation responses of its nervous system. Two stimuli that were once unique had become too similar for the dog to differentiate between; the result was an induced neurosis.
Pavlov and his associates also pioneered the use of negative or painful stimuli in experimental conditioning. Another Pavlov student, M. Initially, the shock was always applied to the same part of the dog's body. This experiment proved to Pavlov and his colleagues that neurotic or maladaptive behavior—in this case, the loss of defensive reflexes when the subject was placed in a painful or dangerous situation—could be induced in the laboratory.
Perhaps more importantly, this finding laid the groundwork for the concept that the conditioning of neurotic behavior could be reversed, a method known as counter-conditioning. Main points Pavlov devoted considerable time to the study of sleep and hypnosis; he considered both states as forms of progressive "cortical inhibition" of the nervous system.
Representing them as two points along a continuum, Pavlov portrayed sleep as complete, diffuse internal inhibition of the cortex and hypnosis as a "partial sleep" state. According to Pavlov, certain conditioned reflexes, such as the salivation response, remained in his animal subjects during hypnosis, while other reflexes related to movement disappeared.
Pavlov concluded that the reflexes that remained did so either because they were governed by the subcortex rather than the cortex, or because the state of hypnosis was light and did not significantly inhibit the cortex. Explanation In Pavlov's lecture "Conditioned Reflexes: Pathological Disturbances of the Cortex," he discussed experiments in which a dog was hypnotized by applying a physical restraint or by placing the animal on its back.
According to Pavlov,. The immobility of the animal makes it less noticeable to the enemy, and thus abolishes or diminishes the aggressive reaction of the enemy. Pavlov also described the use of "strong and unexpected stimuli" to induce hypnosis in cases of "hysteria" in man. Strong stimuli were not the only triggers of a hypnotic response.
Pavlov also described other "external stimuli which directly lead to inhibition of the cortical elements. These are of three kinds—monotonously reoccurring weak stimuli, very strong stimuli, and unusual stimuli. Pavlov believed hypnotic conditioning of humans was very similar to that of animals: According to Pavlov, "The classical method consisted in the performance of so-called 'passes'—weak, monotonously repeated tactile and visual stimuli, just as in our experiments upon animals.
Such words are, of course, conditioned stimuli that have become associated with the state of sleep. In this manner any stimulus that has coincided several times with the development of sleep can now by itself initiate sleep or a hypnotic state. The mechanism is analogous to the inhibitory chain reflexes. Pavlov also addressed the concept of hypnotic suggestion in terms of conditioned response.
He theorized that because language is a excitatory stimulus,. This accounts for the large and practically insurmountable influence of suggestion as a stimulus during hypnosis as well as shortly after it. In other words, suggestion works because a it is a novel stimulus and b language, as Pavlov's "second signal," dominates and overrides all other competing stimuli.
Examples The concept of hypnotic inhibition as a reaction to a new and overwhelming stimulus was described in Pavlov's description of an experimental dog that was brought to a large lecture hall filled with people for a demonstration of the animal's conditioned reflexes. Because of the new location and the large audience, the dog became almost catatonic, and while it exhibited a digestive reflex when a conditioned stimulus was presented, it refused to take the food that was presented.

A short time later, it fell asleep in its stand. Pavlov explained that the conditioned reflex remained because the dog was in a hypnotic state due to the unfamiliar stimulus of the lecture hall. After a time, the animal's diffuse inhibition had spread throughout the cortex and subcortex, triggering sleep.
Pavlov also related the story of a dog that was left in its stand or experimental harness for hours at a time between experiments. Eventually, the dog would shift into a hypnotic or pre-sleep stage immediately upon entering the experimentation room, and it would fall asleep within ten minutes if the experiment was not begun. It had been conditioned to associate the monotony of the room with the inhibited sleep state.

Russia during Pavlov's lifetime was in constant turmoil. He lived through the reigns of four tsars, a world and civil war, a revolution, and two socialist governments. When Pavlov was born in , Russian society was on the cusp of significant change. Since medieval times, Russia had been bound by a rigid class structure: many poor serfs ruled by a few wealthy, land-owning aristocrats, all of whom were subject to a supreme ruler called the tsar.
Tsar Nicholas I ruled Russia from to Near the end of his reign, his army suffered a devastating defeat in the Crimean War , eventually surrendering to France and England in Nicholas' son and successor, Alexander II , had to bear the burden of his father's failures. In order to return Russia to international prominence, Alexander initiated the Great Reforms, which included rapid industrialization, infrastructure improvements, and removal of censorship restrictions.
Most importantly, Alexander II also became a great patron scientific research. For young students such as Pavlov, this abandonment of state-sanctioned censorship and support of science was very exciting. In order to ensure the success of his reforms, the tsar decided to abolish serfdom. In , he granted freedom to the approximately 50 million Russian serfs, much to the chagrin of the landed nobility.
With greater Russian freedoms and relaxed censorship, public discussion of a wide range of issues became commonplace. Journals were published that covered virtually every aspect of Russian life. Lewes Practical Physiology, inspired Pavlov's interest in science. A failed assassination attempt caused Alexander to roll back many of the reforms he had instituted during the previous two decades.
Alexander appointed six military governor-generals to enforce a stringent censorship system. He banned controversial books throughout Russia, and arrested and imprisoned many critics of the government. The renewed repression intensified revolutionary opposition to Alexander's government. A second assassination attempt succeeded in , and the new tsar, Alexander III, vowed to stamp out all revolutionary activities and regain governmental control.
He reduced access to education, established 'land captains' to beat the peasantry for committing minor offenses, and exiled or executed members of revolutionary groups. Even with this dramatic shift in public policy, however, Russian industrialization grew at a faster rate than that of any other European nation during the s.
Despite the booming economy, however, working and living conditions in the urban areas were deplorable. Newlyweds Ivan and Serafima Pavlov suffered from these difficulties; one of Pavlov's biographers reported that the couple once found their infant son covered in lice. Ivan's later appointment to the Institute of Experimental Medicine, however, would improve their lifestyle considerably.
Famine became commonplace and discontent rose throughout the nation. Once again, revolutionary groups began to grow in size and strength. 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. Behaviorism is a theory that suggests human and animal psychology can be understood by studying observable actions.
Behaviorists believe all human behavior is learned by interacting with the environment. Consequently, any person can be trained to become an expert in any task, regardless of his or her personality, culture, or genetic traits. Behaviorism was developed by American psychologist John B. Watson in He was greatly influenced by the work and observations of Ivan Pavlov.
Watson believed all facets of human psychology could be explained by Pavlovian conditioning. He denied the existence of the mind, believed all humans begin as a blank slate, and claimed speech, emotional reactions, and other complex behaviors were nothing more than learned responses to environmental stimuli. Another prominent behaviorist who was heavily influenced by Pavlov is Burrhus Frederic Skinner.
While Watson expanded on methodological behaviorism, Skinner pioneered a different approach called radical behaviorism. Skinner is widely considered to be the father of operant conditioning—a learning process that is different from classical conditioning. Although many people think Pavlov did not care about studying things that could not be measured, he never made those claims himself.
In fact, he viewed the human mind as a great mystery. If scientists want to understand the human mind, the process has to begin somewhere. Pavlov believed the best approach was to begin with observation and hard data.
Classical conditioning has had a big impact on modern-day learning strategies. Although Pavlov worked with animals, he always believed the principles of classical conditioning can be applied to humans. Just as Pavlov used different stimuli to increase or decrease specific behaviors in his dogs, many teachers change their tools, instructions, or environment to influence the behavior of their students and increase learning.
If a teacher is faced with an ongoing problem behavior from a student, the teacher may try to eliminate or change the behavior. One way to do this is by changing something in the learning environment that triggers that specific behavior. So the teacher may move the student to a different seat, change the lights in the classroom, or close an open window if they trigger the bad behavior.
The teacher may also try to change her content or modify the way it is presented in order to boost learning. These strategies are particularly effective for teaching people with behavior problems or learning disabilities.

They have been implemented in many schools, homes, and health centers around the world. Pavlov published many research papers and lectures throughout his long professional career. Some of his more notable works have been compiled into a few books such as The Work of the Digestive Glands , Conditioned Reflexes , and Psychopathology and Psychiatry Todes and published in Pavlov was nominated for the Nobel Prize from to However, he did not win the prize for the first three years because his nominations were tied to a variety of findings rather than a specific discovery.
When he was first nominated in , he was already well known among physiologists, especially those who studied digestion. However, Pavlov's research on conditioned reflexes was not published until and it may have taken a while for this work to penetrate the field of psychology. He received the award for his outstanding research on digestion in animals.
He viewed them as very valuable for his work. When his dogs eventually died, he found effective ways to get more. He would take in strays or even pay thieves to steal dogs from other people. After Pavlov won the Nobel Prize, he drew the attention of many other scientists from around the world. American psychologists, in particular, became more aware of his work and were more willing to test his findings on conditional reflex.
Throughout his life, Pavlov was never easy to get along with. In his childhood days, he often felt uncomfortable around his parents. He was also known to be a volatile and difficult student.
Ivan pavlovs biography children: Ivan Pavlov (born September 14 [September 26, New Style], , Ryazan, Russia—died February 27, , Leningrad [now St. Petersburg]) was a Russian physiologist known chiefly for his development of the concept of the conditioned reflex.
When he opened his lab as an adult, his staff knew to avoid him if he was having one of his many bad days. 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, 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.
