The sexual revolutions before the sexual revolution. The dogs salivating for food is the unconditioned response in Pavlov's experiment. Take a closer look at Ivan Pavlov's life and career in this brief biography.

The concept of classical conditioning is studied by every entry-level psychology student, so it may be surprising to learn that the man who first noted this phenomenon was not a psychologist at all.
