These unusual responses intrigued Pavlov, and he wondered what accounted for what he called the dogs' psychic secretions (Pavlov, 1927). External bodily experiences, such as the sense of pain, are more readily conditioned with external stimuli, such as a tone or light, which manifest outside the body.
