”Sleep-learning, or presenting information to a sleeping person by playing a sound recording has not been very useful. Researchers have determined that learning during sleep is “impractical and probably impossible.” But what about daydream learning? Subliminal learning is the concept of indirect learning by subliminal messages. James Vicary pioneered subliminal learning in 1957 when he planted messages in a movie shown in New Jersey. The messages flashed for a split second and told the audience to drink Coca-Cola and eat popcorn.
A recent study published in the journal Neuron used sophisticated perceptual masking, computational modeling, and neuroimaging to show that instrumental learning can occur in the human brain without conscious processing of contextual cues. Dr. Mathias Pessiglione from the Wellcome Trust Centre for Neuroimaging at the University College London reported: “We conclude that, even without conscious processing of contextual cues, our brain can learn their reward value and use them to provide a bias on decision making.”‘
