  1. 1. How Sleep Affects Learning by Roman I. Rosenast
  2. 2. How important is sleep? <ul><li>A lot of research shows that sleep is a vital component in many things. Sleep is more important than many people believe. Studies find that it helps secure memories and aid learning.  </li></ul>
  3. 3. How important is sleep? <ul><li>This has given us: </li></ul><ul><ul><li>A better understanding of how sleep and wakefulness contribute to learning. </li></ul></ul><ul><ul><li>The understanding of how important sleep is and its ability to benefit the brain. </li></ul></ul><ul><ul><li>Ways to use sleep to boost learning in healthy people and possibly people recovering from brain injuries. </li></ul></ul>
  4. 4. How important is sleep? <ul><li>The notion that sleep is important for learning has been researched by scientists for years. Recently, however, advances in neuroscience have led researchers to carry out a variety of careful studies in both humans and animals, which provide clear evidence that sleep is indeed important for at least some types of memory and learning. In particular it seems to secure memories, termed procedural memories, which help people learn skills. Thanks to procedural memories, you can master dribbling, improve your shot, or learn a new trick. </li></ul>
  5. 5. How important is sleep? <ul><li>Even a nap in the middle of the day may benefit some learning, according to a recent study. Researchers found that scores on a test of procedural memory worsened over the course of four daily practice sessions. Possibly this &quot;burnout&quot; occurs because the brain can only take in so much information before it has a chance to secure the memory of it through sleep. It turned out that a half-hour nap after the second session prevented further deterioration. An hour nap improved performance in later day sessions. </li></ul>
  6. 6. How important is sleep? <ul><li>This goes to show that the amount of memory recorded in the brain can be closely related to the amount of sleep someone gets after doing activity. </li></ul>
  7. 7. How important is sleep? <ul><li>Throughout the day your brain takes in memories as short term memories, these memories are easy to create but do not work after long periods of time. Therefore, the brain uses sleeping  to upgrade those short term memories into long term memories, which require sleeping to create but last  much longer. </li></ul>
  8. 8. How important is sleep? <ul><li>Consequently, in order for you to remember this presentation for a long period of time, you need to sleep relatively well tonight. </li></ul>
  9. 9. the proof? <ul><li>Several studies show that sleep improves memory. In one recent example, participants had to repeatedly type a sequence on a keyboard. A group trained in the morning and then tested 12 hours later showed no significant improvement. But a full night's sleep improved their performance by almost 20 percent . Another group, trained in the evening, improved their performance by about 20 percent after a full night's sleep. But after another 12 hours of staying awake, they showed hardly any improvement. This shows that sleep, not time, aids the learning. </li></ul>
  10. 10. the proof? <ul><li>Fact (kinda) : A good night's sleep improves learning by about 20 percent. </li></ul>
