Sleep, learning and memory

Sleep, learning and memory.


Babies alter and preserve memories during those many naps they call for during the day, a new study suggests. "We discovered that sleeping shortly after scholarship helps infants to retain memories over extended periods of time," said study framer Sabine Seehagen, a child and adolescent psychology researcher with Ruhr University Bochum in Germany. "In both of our experiments, only those infants who took an extended catch forty winks for at least half an hour within four hours after wisdom remembered the information" majestic. The study doesn't definitively confirm that the naps themselves domestic the memories stick, but the researchers believe that is happening.



And "While people might assume that infants become proficient best when they are wide awake, our findings suggest that the time just before infants go down for sleep can be a particularly valuable lore opportunity". Scientists have long linked more sleep to better memory, but it's been unclear what happens when babies lavish a significant amount of time sleeping. In the new study, researchers launched two experiments online. In each one, babies elderly 6 months or 12 months were taught how to slaughter mittens from animal puppets.



Then some of the babies took a nap for a half-hour and some didn't. A unalloyed of 216 babies were tested. Then the researchers tested the babies to see if they remembered how to rub the mittens either four or 24 hours later. The researchers found that only the babies who'd entranced naps after learning actually remembered what they'd learned, especially after 24 hours. Study initiator Seehagen said it's "quite unlikely" that the babies who didn't nap call to mind less because they were tired.



Still, she said more research is needed to confirm the results. So, how many naps do babies emergency and how long should they be? "The small number of studies makes it difficult to make definite recommendations to parents," said Angela Lukowski, an assistant professor of psychology and social behavior at the University of California, Irvine. However, "the schooling for parents seems to be that napping after knowledge may help infants remember information over time.



She added that naps of at least 30 minutes seem to be helpful, although there hasn't been much, if any, probing into shorter naps. As for adults, don't pester about napping as a memory aid. "There are many studies in the literature showing the benefit of naps for adults, but adults do not beggary to nap to retain new memories," said Rebecca Gomez, an ally professor of psychology at the University of Arizona scriptovore. The new study is published in this week's outgoing of the Proceedings of the National Academy of Sciences.
