Nov 07, 2019 · Ivan Petrovich Pavlov (September 14, 1849 - February 27, 1936) was a Nobel Prize-winning physiologist best known for his classical conditioning experiments with dogs. In his research, he discovered the conditioned reflex, which shaped the field of behaviorism in psychology.

Ivan Petrovich Pavlov was an eminent Russian physiologist and psychologist who devised the concept of the conditioned reflex. He conducted a legendary experiment in which he trained a hungry dog to drool at the sound of a bell, which had previously been related to the presentation of food to the animal.

Ivan Petrovich Pavlov was born on September 14, 1849, in the village of Ryazan, Russia, where his father was the village priest. His earliest studies were focused on theology, but reading Charles Darwin's On the Origin of the Specieshad a powerful influence on his future interests. He soon abandoned his religious studies and devoted himself to the study of science. In 1870, he began studying the natural sciences at St. Petersburg University.
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.1 "Science demands from a man all his life. 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.2 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. He termed this response a conditional reflex. Pavlov also discovered that these reflexes originate in the cerebral cortex of the brain.3 Pavlov received considerable accl...
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'swritings. 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 1897 text The Work of the Digestive Glands, which centered on his physiology research. Later works that focused on his discovery of classical conditioning include his 1927 book Conditioned Reflexes: An Investigation of the Physiological Activity of the Cerebral Cortex and Lectures on Conditioned Reflexes: Twenty-five Years of Objective Study of the High Nervous Activity (Behavior) of Animalswhich was published one year later.
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.
Ivan Pavlov studied the various processes of digestion, in part by exposing sections of a dog's intestinal canal through surgery. During the 1890s he identified ways in which different parts of the body, through the nervous system, affect movements in the intestinal canal as well as secretion of gastric juice and other secretions.
Ivan Pavlov‘s experiments with dogs are very well-known in the history of psychology. People built a psychological learning theory from his small accidental discovery. Pavlov’s studies have helped us understand associative learning through classical conditioning.

How did experiments on the digestive response in dogs lead to one of the most important discoveries in psychology? Ivan Pavlovwas a noted Russian physiologist who went on to win the 1904 Nobel Prize for his work studying digestive processes. It was while studying digestion in dogs that Pavlov noted an interesting occurrence: His canine subjects would begin to salivate whenever an assistant entered the room. 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. The dogs 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, Pavlov 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 h...
Pavlov's discovery of classical conditioning remains one of the most important in psychology's history. Pavlov’s work has also inspired research on how to apply classical conditioning principles to taste aversions. The principles have been used to prevent coyotes from preying on domestic livestock and to use neutral stimulus (eating some type of food) paired with an unconditioned response (negative results after eating the food) to create an aversion to a particular food.1 Unlike other forms of classical conditioning, this type of conditioning does not require multiple pairings in order for an association to form. In fact, taste aversions generally occur after just a single pairing. Ranchers have found ways to put this form of classical conditioning to good use to protect their herds. In one example, mutton was injected with a drug that produces severe nausea. After eating the poisoned meat, coyotes then avoided sheep herds rather than attack them. While Pavlov's discovery of class...
