- In 1932, Alois Benjamin Saliger patented the Psycho-phone, a device that played recorded affirmations to people while they slept, claiming it could influence the unconscious mind for goals like prosperity and love.
- Early studies on sleep-learning in the 20th century showed promising results, such as soldiers learning Morse code or boys stopping nail-biting, but were flawed due to inability to verify if subjects were truly asleep.
- Research in the 1950s, like that by Charles W. Simon and William H. Emmons, debunked sleep learning by showing subjects were often awake, leading to decades of dismissal as pseudoscience.
- Recent studies, such as those by Karen Konkoly and Ken Paller, have revived interest, using techniques like targeted memory reactivation with scents or sounds to enhance memory during sleep in controlled conditions.
- Experiments with lucid dreamers, such as solving puzzles or answering questions during REM sleep, demonstrate that complex learning and communication can occur while asleep, though results vary and dreams are unpredictable.
- While sleep-learning shows potential, scientists warn of downsides, including sleep disruption and the risk of imposing wake-centric values on sleep, which may undermine its natural restorative functions.
