Early psychological theory considered the learner to be a tabula rasa or blank slate, dependent for learning on training or conditioning.
Classical or Pavlovian conditioning is based on a learning model of this type, where learning is generated through experience with the environment. John Watson's classical experiment in conditioning an emotional response in a human subject, Little Albert, provides an example, as does his most famous boast:
Give me a dozen healthy infants, well-formed, and my own specified world to bring them up in and I'll guarantee to take any one at random and train him to become any type of specialist I might select-doctor, lawyer, artist-regardless of his talents, penchants, tendencies, abilities, vocations and race of his ancestors.
