Are you one of those students that doesn’t get any sleep during important exam weeks? Do you study all night on red bull and coffee?
Then you are making a mistake, according to a study presented in Boston at the American Academy of Neurology’s 59th annual meeting in 2007. They found out that, while you sleep, your brain strengthens the memories you made during the day.
The researchers studied 48 healthy adults aged 18-30. The team split participants into four groups. Participants in all four groups memorized word pairs. One group was tested on the word pairs at the end of the day. Another group took the same test the following morning, after sleeping at home. Their test scores were similar.
The remaining two groups got an extra challenge. Right before the test, they saw another set of word pairs that was very similar to the word pairs they had memorized. Those participants were tested on both sets of word pairs. The point was to see whether their memory was distracted by the new set of word pairs.
The students who slept at home before the tests performed best. They correctly identified about three-quarters of the word pairs.In comparison, the students who took the test before going home for the evening correctly identified about one-third of the word pairs.
“This is the first study to show that sleep protects memories from interference,” researcher Ellenbogen says in an American Academy of Neurology news release.”These results provide important insights into how the sleeping brain interacts with memories: It appears to strengthen them” he says.
So if you study for an important test, don’t pull an all-nighter, just go to sleep! You now have a scientific excuse. But is probably still is a good idea to study with eFaqt as well. Just to be sure!
