3.2.4. The interpretation of results

3.2.4.1. For interpreting the results and putting the diagnosis E.P.Ilyin recommends to use a diagnostic key represented in table 10.

Table 10 – A diagnostic key of investigating NS mobility-inertness

The result of investigation	The diagnosis
B1 is more than b2 B1 is less or equal to b2 A1 is less or equal to a2 A1 is more than a2	The inertness of energization The mobility of energization The mobility of inhibition The inertness of inhibition

If b1 is more than b2, the examinee has a long lasting process of energization. If b1 is less than b2, the examinee’s process of energization disappears quickly.

If a1 is more than a2, the examinee has a long lasting process of inhibition. If a1 is less than a2, the examinee’s process of inhibition disappears quickly.

3.2.4.2. We’ll substitute the corresponding figures from table 9.

a1 = +14 is less than a2 = +19. The diagnosis – mobility of inhibition.

b1 = -13 is less than b2 = -15. The diagnosis – mobility of energization.

3.2.4.3. A more concrete diagnosis of any quality presupposes the definition of a corresponding point on a continuum of diagnosed quality. In this connection E.P.Ilyin introduced a quantitative criterion of distinguishing the examinees according to their degree of “mobility-inertness” by way of dividing a2 to a1 and b2 to b1.

On the basis of this criterion we have worked out a standard diagnostic scale of NS mobility-inertness (see appendix 2, item 2.2). This scale is used for the interpretation of coefficients of mobility-inertness both of processes of energization and the processes of inhibition of NS.

3.2.4.5. In the example from table 9 the coefficient of inhibition is equal to:

19: 14 =1,36. This index corresponds to 18 numbers of a diagnostic scale (mobile NS).

The coefficient of energization is equal to:

15: 13 =1,15. This index corresponds to 15 numbers of a diagnostic scale (a boundary between average and mobile NS).

3.2.5. Some possible ways of practical usage

of method and results of diagnostics

Mobility-inertness of nervous system influences various aspects and characteristics of a person’s activity: speed of reaction, quickness of processing of the information, sizes of information blocks, which help a person to think, peculiarities of behavior, communication, etc.

In this connection it is necessary to take into account the results of the diagnostics of NS mobility-inertness in the process of forming the individual style of activity and behavior, in the process of professional selection and professional consultation.

For example, driving any vehicle makes great demands to the quickness of driver’s reaction to different signals and situations. For this reason people with mobile NS have an advantage. Those people who have inert nervous system should pay special attention to the necessity of preliminary foreseeing the situation.

So, an inert driver should know how to prognosticate the appearance of pedestrians on the road, he should react to signals of traffic lights beforehand, etc. When training pilots with inert NS you should pay special attention to the formation of algorithmic sequence of operations in extreme and difficult situations.

The algorithmization of activity essentially accelerates the execution of adequate actions at the expense of spending less time on making decisions and because of increasing the degree of automatization of activity. These recommendations can be given to an operator, air manager, train driver, pilot, etc.

As it is shown in special research (Yu.A.Tsagarelly, 1989), NS mobility-inertness stipulates the quantity of acoustic-motive representations, which is the necessary component for a musician-performer. The more inert NS is, the larger blocks you need to think with. The more mobile NS is, the fewer blocks you should operate with.

Many other kinds of activity such as sports, driving technical vehicles, industrial activity, etc. have similar dependence of block sizes of motive representations on the mobility-inertness of NS.
