Our memory defines ourselves. From our childhood memories, up to the moment when we remember where we left our keys, the memory plays a vital role in our everyday lives. There are many unknown facts about our brain, but down billow we have a list of 5 facts talking about this subject:
1. Our short-term memory is limited. experts believe that you can keep around seven thing in our short-term memory for a limited period, which is about 20 to 30 seconds. Of course, there are strategies or exercises that can help us improve this type of memory. One good example is gathering similar pieces of information into smaller groups.
2. Tests help us remember - Though it seems that repeating the information so many times may be the best way to remember it, researchers have discovered that tests are a good method to improve your learning skills. A study showed that students who learned and then took a test, could even remember information that did not appear in the test. On the other hand, students who didn't take a test, hardly remembered what they had learned.
3. Amnesia isn't what we see in the movies - Have you ever watched a movie where a person who had suffered a shock lost his memory, and then, suddenly, he recovers it after the second shock? You need to know that there are two types of amnesia: anterograde amnesia and retrograde amnesia. The first one makes impossible to memorize new things, while the other one doesn't let us remember things from the past.
4. Our long-term memory "takes a brake" during our sleep. This is why we can dream about a thing that we saw that day, and from the same reason, we can't remember our dream after we wake up. Though we dream a few times during a night, these dreams aren't kept in our long-term-memory.
5. TV can affect your brain - It's true that sitting in front of the TV after a log and stressful day sounds good, but you shouldn't watch TV more than two hours a day. A study showed that with every extra hour you spend in front of the TV, the risk of developing Alzheimer's later is increased by 1.3%. All in all, think, practice, test your brains!
