Behaviorism, Ivan Pavlov and Beyond

Ivan Pavlov (1849-1936)

Pavlov has been on the side because he did what he did when no one was paying attention, and he did it in Russia and communication wasn’t as good as now, no one knew that there was a guy in Russia setting the stage for classical conditioning. You read a few stories in the book and he’s a brilliant and bizarre kid. When Darwin published the origin of species when he was 10 and he loved Darwin and he decided to study medicine. He went to st. pittsuburg and studied physiology. Read some of the stories from the book, he was workaholic. He hated psychology, once he got going on the condition reflex, he discovered that he has intersection with psychology, he hated it and threatened everyone in his lab that if they mention psychology he will kick them from the lab. He studied the gastric reflexes in dogs, in the 1890s, he was ever more bothered by a phenomena that messed up his date: dogs salivate before they got the food, they messed up his time measurement system, since he hated psyc, he refused to study it. He got a nobel prizes in 1904 on his work on the gastric system not on psychology. He didn’t know that the condition reflex is what he’s looking it. UCS (food), UCR (salivation). UCS+CS (bell) = UCR…but later after many trials you can simply present a CS and will get the CR. Although it took us 5 minutes to understand it took him decades to set up. He had an elaborate theory on all of what happens in the brain, he thought he was studying window into the brain.

5 processes (he spent many variations to do them, until he established classical condition) (by about 1910 watson knew he existed because he mentioned condition reflex in his nobel prize lecture) (no one knew the full effect until 1927 because of bad publication and all was in Russian) (he had a large lab with lots of dogs and lots of students working 14 hours in the lab)

1) Acquisition (timing): he studied on how actually the pairing UCS and CS take place, can you first introduce CS...
