Sleep-learning is found in influential
science fiction and other literature. The following examples are listed chronologically by publication or original air date, when known. • In
Hugo Gernsback's 1911 story
Ralph 124C 41+, one finds the Hypnobioscope, a sleep learning device. • In
Aldous Huxley's 1932 novel
Brave New World, it is used for the
conditioning of children into the novel's fictional future culture. In the novel, sleep-learning was discovered by accident when a Polish boy named Reuben Rabinovitch was able to recite an entire radio broadcast in English after a radio receiver was left on in his sleep. The boy was unable to comprehend what he had heard via hypnopædia, but it was soon realized that hypnopædia could be used to effectively make suggestions about morality. • In Robert Heinlein's 1948 novel
Space Cadet, the character Matt Dodson is taught to speak Venutian (the language of the planet Venus) while under drug-aided hypnosis. He surprises his Venus-born friend Oscar by spontaneously reproving him when Oscar utters a curse in Venutian. (Later in the novel, Matt appears to have forgotten what he learned and relies on Oscar for translation.) • In the
BBC Radio series
Journey into Space (1953–1958), during the second and third parts of the trilogy, there were said to be
Martians abducting people from the Earth and conditioning them to obey instructions or to make them believe things that were not true. The inception of this conditioning involved putting the subject into a
hypnotic sleep and appraising them of a certain situation; once they awoke they would believe it, regardless of the validity. • Teaching relatives while they are asleep to influence their waking behavior is at the heart of
Guido Martina's and
Giovan Battista Carpi's
Disney comic story
Paperino e la cura suggestiva ("
Donald Duck and the Suggestive Cure"), first published in
Topolino #187 (May 25, 1958). • In a 1961 episode of
My Three Sons, "A Lesson In Any Language", Mike connects a
phonograph to an automatic timer to play
Spanish lessons while he sleeps. Steve and Bub ultimately end up sleeping in the room and are able to speak fluent Spanish the following day. • In
Anthony Burgess's 1962 novel
A Clockwork Orange, it is used to reverse the effects of the
Ludovico Technique, a form of conditioning, which was used on the main character Alex to make him incapable of violent behavior. The conditioning was a new technique which was supposed to rehabilitate violent criminals in a short period of time, but which resulted in Alex
attempting suicide. This reflected very badly on the government, which had sanctioned the experiment, so hypnopædia was used to undo the conditioning. • In 1954 Günter Spang wrote a children's book called
Lohengrin schwant etwas, meaning Lohengrin has a good idea, in which a bunch of schoolchildren take an easy way out of studying by learning in their sleep. • In a 1963 episode of
The Patty Duke Show, "The Conquering Hero", Cathy tries to help a failing basketball player pass a quiz. She suggests that the latest scientific method of "
subconscious learning" will help. She records the lessons on a tape which plays repeatedly while he is asleep. He passes the quiz after the answers "come to him" while looking at the questions. • In the 1965 episode of "I Spy" titled Chrysanthemum, the assigned partner of Bill Cosby and Robert Culp's characters, Maximilian de Broget claims to have learned Mandarin Chinese in his sleep. • In the 1965 movie ''
The Monkey's Uncle'', a college student connects a phonograph to an automatic timer, which plays to sleeping students the voice of a girl reading their lessons aloud. This backfires in class, however—when asked to give an oral report, the students speak, but in the girl's voice. • In the 1966 novel
Flowers for Algernon, an intellectually disabled 37-year-old, Charlie Gordon, has an operation to increase his intelligence. Professor Nemur and Dr. Strauss then give Charlie a "teeching mashine that werks like T.V." Charlie explains to Professor Nemur that . • The 1976 film ''

Coach Z takes it home and listens to it while he sleeps, and the next day is able to pronounce "job" correctly, but forgets Homestar's name. • The twins
