Sleeping Helps With Memory Retention
Guzzling coffee and pulling an all-nighter cramming for an exam or presentation has been a necessary evil for many people at some point in time. While most know that being extremely sleep-deprived harms mental performance, a recent study has found that sleeping actually aids in learning and memory formation.
In this study, published in the Journal of Neuroscience, researchers taught participants new vocabulary words and tested their recall of the words two times: once immediately after learning them, and again hours later. One group learned the words in the morning and was re-tested in the evening; the second group learned the words in the evening and was re-tested the following morning, after getting a full night of sleep.
Not only did the group who slept in between tests perform better than the control group, they actually performed better on the test in the morning than on the test administered directly after learning the words.
