"Pavlov and all that sort of stu ff"

Ivan Pavlov was a Nobel Prize winning Russian scientist famous for being the first to describe "classical conditioning", also known as "Pavlovian conditioning".  The best-known of his experiments into conditioning involved training dogs to salivate at the sound of a bell by causing them to associate the bell with food being served to them.
