Physiological basis of memory is considered to be the formation and consolidation of temporary nerve connections in the cerebral cortex. Arousal is triggered each time the perception of the signal does not disappear immediately, but gradually fades out, leaving a trace in the form of residual weak excitation. Under the influence of excitation in the CNS structural changes that are stored on a more or less long term, depending on the nature of the stimulus, the duration and strength of his actions. If the nervous system has the capability to keep track of excitations and play them, it would be impossible to accumulate experience. The peculiarity of the nervous system to preserve the traces of excitation is the basis of memory and learning (B. F. Lomov, 1966; M. I. Zinchenko, G. C. Repkina, 1964; D. the Broadbent, 1966, and others).
Numerous studies memory in different age periods indicate different degrees of reduction misticheskih functions (the learning process, save, play, short-term, long-term and logical-semantic memory).
The weakening of memory in the aging process is adaptive in nature that with age leads to the predominance of logical and systematic development over the mechanical memorization. So, B. A. Grekov (1968) when studying the different types of memory method of structural analysis has established that suffers a mechanical component logical-semantic memory. Semantic same component it persists over a long time and becomes greater share in the entire memory.
The most pronounced age memory loss is detected when using tests that require the active execution (motor, combined, integrated, creative), and when performing tasks, built on experience, in particular professional, indicators of the most high.
With age the memory processes are subject to changes, which are expressed in the reduction of the number of memorized material, the lengthening of the process of remembering and an increasing trend towards a decrease in the accuracy of remembering. Older people play function verbal marks, fixed within the past life, is carried out over a longer period than the young.
The function of preserving the memory, especially material that can be easily organization, with age does not change significantly. Regardless of the nature of the material and method of training, short-term memory decreases more slowly. This type of memory less exposed to noise due to previous associative links. Therefore, to characterize the health typically learn about short term memory, which reflects the ability of one-time saving information.
In the study of short-term memory (for memorizing were presented with 6 figures) marked its gradual deterioration with increasing age equally in men and women (table. 11).

Among women, the results of direct remember, as a rule, higher, than at men.
Our experience suggests that people of intellectual work to assess the mental health of the most characteristic features of the short term memory in combination with thought processes, so performance was assessed also on the effectiveness of the performance of simple mental arithmetic operations such calculations.
