Memory — Is securing, maintaining and further reproduction of a man of his experience. Memory is the basis for the acquisition of knowledge and skills and creates the opportunity for training and development of the mind.
Sensory memory — The most primitive process carried out at the receptor level. The information in it is not delayed by more than a quarter of a second: for it is solved the question of whether it will attract the attention of the higher parts of the brain. If it does not, then less than a second, and erased the traces of sensory memory is filled with new signals.
Short-term memory. In that case, if the information transmitted receptors attracted brain, it can in a short period of time stored, and during this time the brain interprets and processes it. At the same time solved the question of whether this is sufficient information important in order to be transmitted to the long-term storage. Short-term memory characterized not only by a certain duration retention of information, but also the capacity, that is, the ability to simultaneously store a number of disparate pieces of information. On average, short-term memory capacity is limited to family members.
Long-term memory. Of the few items that briefly trapped in short-term memory, the brain selects what will be stored in long-term memory. Capacity and duration of long-term memory in principle unlimited. They depend on how important it is for humans to remember information as well as the method of its encoding, organizing, and finally play.
