Emotional memory
A study was described in Scientific American, during which half of the subjects were sleep deprived during the last 36 hours. The aim of the follow-up survey was to rate the emotional content of words as positive., negative or neutral. After two nights of restorative sleep, the subjects took the test again., during which they were asked to remember, what words did they see.
Compared to the control group, test subjects, sleep deprived, remembered on 40% fewer test words. Such a severe negative effect on memory in itself should be avoided., but further more.
In fact, across all three emotional categories, the effect was not the same.. The subjects were forgotten 50% words with positive or neutral emotional content, only 20% words with negative emotional content. In this way, after sleep deprivation, negative memories, least, twice as strong, than something positive or neutral.
The results of the study indicate that, what, when you are sleep deprived, you form twice as many memories of negative events in your life, what about the positive.
Consolidating memory
Over the past two decades, we have witnessed numerous discoveries, which showed the important role of sleep in memory processing. Sleep after learning leads to selective stabilization, analysis and consolidation of new memories. At the same time, he controls that, what we remember and how we remember. Everything, what do you think is important, will be selectively saved, while you sleep.
Let's take another study as an example.. The subjects are told, what tasks they will and will not solve the next day, after which they are provided with a normal night's sleep. The next day, the subjects improve their performance only in those tasks, which they promised to give.
Results of this kind indicate that, that our memory in the course of evolution has developed so, to help us improve follow-up work, and sleep seems to be one of the most important components of this system. Interfering with it, you undermine your natural ability to use previous experiences to improve your performance the next day.
Complex processing
A number of experiments have been carried out, during which the subjects were to explore the likely relationship between the pictures on the cards and their explanation.
If the subjects were tested first in the morning, and then in the evening, no changes were observed. However, if they were tested first in the evening, and then allowed to sleep and re-tested the next morning, they showed improvement in 10%. Anyway, the sleeping brain actually improved understanding of the relationship between images and their explanations.
Often happens, what, puzzling over something in the evening, you find a solution the next morning shortly after waking up. In this case, the expression "the morning is wiser than the evening" has a genuine physiological basis. Our brain can solve problems and form an understanding of complex things during sleep.. And where, if not in poker, we are constantly faced with solutions to problems and explanations of difficulties.
