New research shows that children who get a good night's rest have increased memory. This could explain why children who don't sleep well also don’t perform well in school.
The study suggests children who sleep better more effectively convert implicit knowledge (doing something without actually knowing how) to explicit knowledge (information stored in the mind).
Researchers of the University of Tubingen Germany instructed 28 children and adults to press buttons on a panel in a sequence, using the trial and error method. After a night’s rest, participants were asked to recall the sequence.
Children performed much better on this explicit memory test than adults, according to the findings. Researchers noticed that children have slower brain wave activity during sleep, which is linked to explicit memory performance.
This specific brain activity has also been linked with the ability to learn, think and remember and is believed to be critical to the restoration of mood.
Lead researcher, Dr. Jan Born, explained that children showed stronger hippocampal (major element of the brain) activation at explicit knowledge retrieval.
"Our data indicate the superiority of children in extracting invariant features from complex environments, possibly as a result of enhanced reprocessing of hippocampal memory representations during slow-wave sleep," said Born.
