Ivan Pavlov was a Russian physiologist known for creating classical conditioning. He was born in 1849. Ivan Pavlov belonged to the school of thought of Behavioralism. Behavioralism are psychologist who analyze how organisms learn or modify their behavior based on how they respond to events in the environment. He is important to psychology because he was able to make people learn a certain way with their behavior and how they respond to events that happen around them and in there life. He started by training a dog to salivate from a treat. He added a bell sound to that treat so the dog began to salivate when he heard a bell before he even saw the treat. He paired a unconditioned stimulus and a neutral stimulus to produce conditioned response.
