Developmental Psychology: A nap promotes long-term memory – Business Week

A new study shows that the memory is increasing in young children when they sleep after an instructive experience.

A nap after learning strengthens according to a study in young children, the long-term memory. As researchers from Bochum and the British Sheffield found out memories of facts and events are better saved if the child sleeps for a educational experience.

The psychologists visited more than 200 babies home and studied the memory of children with puppets test. All results are published in the “Proceedings” of the US National Academy of Sciences (“PNAS”).

“That the Council” sleep time over it “works in adults, is already well established scientifically,” said the developmental psychologist Sabine Seehagen of the Ruhr-University Bochum, who led the study. Even in school children has been studied the phenomenon. “Because young children learn a lot and remember and also sleep a lot, we have looked at babies aged six to twelve months . “

The researchers played the children from Bochum and the surrounding area on a first visit with a hand puppet certain actions before. At the next meeting they observed which tried these actions to imitate the child when he saw the hand puppet again.

Some of the small subjects had slept for at least half an hour at a time within four hours after the puppet, the other remained awake or dozed off only very briefly.

A control group of children was the first visit to see any action; thus could be tested how the children reacted spontaneously when they saw the doll.

The infants with sleep made significantly more actions than by children in the control group, as noted, the psychologists. The situation was different in the experimental participants who had stayed awake. They had not realized according to the study, which the researcher had shown us a hand puppet.
