Pavlov's dog experiments played a critical role in the discovery of one of the most important concepts in psychology: Classical conditioning. While it happened quite by accident, Pavlov's famous experiments had a major impact on our understanding of how learning takes place as well as the development of the school of behavioral psychology.

Classical conditioning is sometimes called Pavlovian conditioning. How did experiments on the digestive response in dogs lead to one of the most important discoveries in psychology? Ivan Pavlov was a noted Russian physiologist who won the Nobel Prize for his work studying digestive processes. While studying digestion in dogs, Pavlov noted an interesting occurrence: His canine subjects would begin to salivate whenever an assistant entered the room. The concept of classical conditioning is studied by every entry-level psychology student, so it may be surprising to learn that the man who first noted this phenomenon was not a psychologist at all.

In his digestive research, Pavlov and his assistants would introduce a variety of edible and non-edible items and measure the saliva production that the items produced. Salivation, he noted, is a reflexive process. It occurs automatically in response to a specific stimulus and is not under conscious control. However, Pavlov noted that the dogs would often begin salivating in the absence of food and smell. He quickly realized that this salivary response was not due to an automatic, physiological process.

Based on his observations, Pavlov suggested that the salivation was a learned response. Pavlov's dog subjects were responding to the sight of the research assistants' white lab coats, which the animals had come to associate with the presentation of food. Unlike the salivary response to the presentation of food, which is an unconditioned reflex, salivating to the expectation of food is a conditioned reflex.

Pavlov then focused on investigating exactly how these conditioned responses are learned or acquired.

In a series of experiments, he set out to provoke a conditioned response to a previously neutral stimulus. He opted to use food as the unconditioned stimulus , or the stimulus that evokes a response naturally and automatically. The sound of a metronome was chosen to be the neutral stimulus.

The dogs would first be exposed to the sound of the ticking metronome, and then the food was immediately presented. After several conditioning trials, Pavlov noted that the dogs began to salivate after hearing the metronome. Pavlov's discovery of classical conditioning remains one of the most important in psychology's history. Pavlov's primary interests were the study of physiology and natural sciences.

He helped found the Department of Physiology at the Institute of Experimental Medicine and continued to oversee the program for the next 45 years.

If you had two lives that would not be enough for you. Be passionate in your work and in your searching, " Pavlov once suggested. So, how did his work in physiology lead to his discovery of classical conditioning? While researching the digestive function of dogs, he noted his subjects would salivate before the delivery of 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 appointment to the Russian Academy of Sciences and the Nobel Prize in Physiology. He died on February 27, Many outside of psychology may be surprised to learn that Pavlov was not a psychologist at all.

Not only was he not a psychologist; he reportedly was skeptical of the emerging field of psychology altogether.

However, his work had a major influence on the field, particularly on the development of behaviorism. His discovery and research on reflexes influenced the growing behaviorist movement, and his work was often cited in John B. Watson's writings. Other researchers utilized Pavlov's work in the study of conditioning as a form of learning.

His research also demonstrated techniques of studying reactions to the environment in an objective scientific method. One of Pavlov's earliest publications was his text The Work of the Digestive Glands , which centered on his physiology research. Ivan Pavlov may not have set out to change the face of psychology, but his work had a profound and lasting influence on the science of the mind and behavior.

His discovery of classical conditioning helped establish the school of thought known as behaviorism. Thanks to the work of behavioral thinkers such as Watson and Skinner, behaviorism rose to be a dominant force within psychology during the first half of the twentieth century.

American Psychologist, 52 9 , DOI: Johns Hopkins Magazine, Todes, D. The next time the dog heard a metronome at any speed, it would salivate. But when only that particular metronome setting was reinforced with food the dog became more discriminating.

As his formulations and models grew more complex, Pavlov was encouraged in his hope that he would be able to approach psychology through physiology. The question is how to analyze this subjective world. Pavlov harbored no sentimental attachment to the old order, which had never been aggressive in funding scientific research. The Bolsheviks promised to do better and, eventually, they did. That which constitutes the culture, the intellectual strength of the nation, has been devalued, and that which for now remains a crude force, replaceable by a machine, has been moved to the forefront.

All this, of course, is doomed to destruction as a blind rejection of reality. Lenin had too many other problems to spend his time worrying about one angry scientist. At first, Pavlov, his wife, and their four children were treated like any other Soviet citizens. Their Nobel Prize money was confiscated as property of the state.

From to , like most residents of Petrograd, which would soon be called Leningrad, the Pavlovs struggled to feed themselves and to keep from freezing. Pavlov grew potatoes and other vegetables right outside his lab, and when he was sick a colleague provided small amounts of firewood to burn at home. Pavlov wanted to see if, as he suspected, universities in Europe or America would fund his research in circumstances that would prevent his dogs and lab workers from starving.

He instructed Petrograd Party leaders to increase rations for Pavlov and his family, and to make sure his working conditions improved. The Soviets came to regard Pavlov as a scientific version of Marx. That year, Stalin began a purge of intellectuals. Pavlov was outraged. Stalin agreed. Pavlov prospered even at the height of the Terror. By , he was running three separate laboratories and overseeing the work of hundreds of scientists and technicians.

He was permitted to collaborate with scholars in Europe and America. Still, his relationship with the government was never easy. Soviet leaders even engaged in a debate over whether to celebrate his eightieth birthday. Kuibyshev was deeply opposed to any state recognition. Classical conditioning remains a critical tool: it is widely used to treat psychiatric disorders, particularly phobias.

But the greater pursuit is for a kind of unified field theory in which psychology and physiology—the subjective and the material realms—would finally be integrated. And so we have entered the age of the brain.

The United States and other countries have embarked upon brain-mapping initiatives, and Pavlov would have endorsed their principal goal: to create a dynamic picture of the brain that demonstrates, at the cellular level, how neural circuits interact.

As Todes points out, while Pavlov examined saliva in his attempts to understand human psychology, today we use fMRIs in our heightened search for the function of every neuron. By Ariel Levy.
