Successful long-term learning happens after sleeping on the new material from the University of London.
Academics from the Department of Psychology at Royal Holloway taught a group of people new words from a fictional language, which unknown to them, was characterised by a rule relating the new words to one another. They found that although learners became aware of the rule within the new language shortly after being taught it, they were unable to apply it to understanding new, untrained words until after a period of rest.Kathy Rastle, Professor of Cognitive Psychology at Royal Holloway, said: “Teachers have long suspected that proper rest is critical for successful learning. Our research provides some experimental support for this notion. Participants in our experiments were able to identify the hidden rule shortly after learning. However, it was not until they were tested a week after training that participants were able to use that rule to understand a totally new word from the fictional language when it was presented in a sentence.”She added: “This result shows that the key processes that underpin long-term learning of general knowledge arise outside of the classroom, sometime after learning, and may be associated with brain processes that arise during sleep.”
