He classical conditioning It is a theory of learning that was discovered by the Russian physiologist Ivan Pavlov. This concept, which has had a great influence in psychology and other areas of study, explains how organisms learn to associate stimuli and responses. In this article, we will explore the research that led Pavlov to describe classical conditioning.
Ivan Pavlov He was born in Russia in 1849. In 1870, he entered the University of Saint Petersburg to study physiology and medicine. During his studies, Pavlov became interested in the relationship between the nervous system and the digestive process, and began conducting research in this field.
In 1891, Pavlov became the director of the Institute of Physiology in St. Petersburg, where he began studying digestive processes in dogs. His experiments focused on the study of saliva secretion in dogs and how this response could be conditioned by external stimuli.
Pavlov observed that dogs began to salivate before they were given food. This response, known as “anticipatory salivation,” was a conditioned reflex that had developed through learning. Pavlov discovered that he could condition dogs to salivate to stimuli that were not directly related to food, such as the ringing of a bell.
To carry out his experiments, Pavlov placed dogs in an experimental enclosure and gave them food after ringing a bell. Over time, the dogs learned to associate the sound of the bell with food, and began to salivate as soon as they heard the bell, even if food was not present. Pavlov called this process “classical conditioning“, because the conditioned response (salivation) had been associated with the neutral stimulus (the sound of the bell).
Pavlov continued to conduct experiments to explore the mechanisms of classical conditioning. He discovered that the strength of the association between the neutral stimulus and the conditioned response could be affected by the timing, intensity, and frequency of the neutral stimulus. He also discovered that classical conditioning was a learned process, and that it could be unlearned if the association between the neutral stimulus and the conditioned response was disrupted.
Pavlov’s work on classical conditioning had a great impact on psychology and other areas of study. He became a model to explain how organisms learn to associate stimuli and responses, and was used in the study of memory, learning, and animal behavior.
Today, the classical conditioning It remains an important concept in psychology and other related disciplines. It has been used to explain a variety of human and animal behaviors, from conditioned fear to addiction and marketing. Pavlov’s research on classical conditioning has left a lasting legacy in science and changed our understanding of how organisms learn.
