Studies have shown that until 20-25 years of age a person's memory improves, until 40-45 it stays at about the same level and then it starts to get weaker. It is difficult to find a person that is satisfied with his memory. But very often the person is just not able to use his memory at the full capacity. To learn how to use the available reserves of your memory is even more important than training it!

Here is some brief useful information about memory and how to use it. First, here is how to use your external memory. External memory is storage of information outside of our brain, mostly in the form of various notes (notebook, computer, etc.) Very important condition: external memory must be very well organized. External memory is considered in a category that fulfills the absence of mental capabilities.

The second is how to correctly organize your memory: to be able to consider its features and understand the principles of its action. Let's assume, you are better at acquiring material by reading it silently. You remember how the text in the book is organized. Additionally, you can easily find the road in an unfamiliar place, easily remember new faces. That means you have good visual memory.

If you perfectly perceive information on hearing it, that means that you are the acoustical type.

For the impellent (motor) memory it is typically fast and easy to remember complex movements. The people that have it absorb the information better if it is combined with walking, whispering, or jumping.

It is important to know, that a person restores all of the knowledge which he has received during the day during sleep. Scientists from Chicago University proved that during sleep a person restores all knowledge that he has received during the day even if by the evening it seems to him that he has forgotten everything. Sleep not only strengthens the new information but also restores the "lost" information.

What else is necessary to know about memory?

" Capacity - quantity of information that is received in a unit of time;

" Strength of holding - time during which we remember the material;

" Accuracy - number of mistakes at reproduction;

" Readiness - speed of reproduction.

The general principles of memory action:

" Principle of selection: Don't keep in memory anything that is useless.

" Principle of a reserve: The part of the information that is necessary to hold in "reserve" is in the external memory.

" Principle of "egoism": Personal interest in a subject is necessary; if you don't have it then somehow connect the boring information with one that is interesting to you.

" Principle of activity: recurrence - mother of learning.

" Principle of seven: It is hard to absorb material if it is in more than seven parts, to make the process of absorbing material easy, break it into chapters with paragraphs.

" Principle of the best schedule: 40-50 minutes of work and 10-15 minutes of rest.

" Principle of the best background: it is necessary to define the surrounding conditions that are favorable to you.
