5.1.2.1. The procedure of diagnostics

3.1.2.1.1. Put the device ATS and your examinee’s right hand on the panel of the device as you did it when making the diagnostics of NS mobility-inertness, i.e. in accordance with item 3.2.2 of chapter III.

The examinee, with his eyes shut, moves the left romper-suit from the extreme left position to the right up to the delimiter and backwards. In order to remember this movement he repeats it three times.

The delimiter is the right romper-suit, which the investigator fixes so that the amplitude of examinee’s movement was equal to 30 divisions of a scale.

5.1.2.1.3. Then take the delimiter away and ask the examinee to reproduce the given interval five times.

5.1.2.1.4. Put down the results of the experiment into column 2 of table 7.

Table 7 – The report of the diagnostics of absolute threshold of sensations due to the accuracy of movement reproduction

№ of procedure	Established interval of relative L1=30, divisions	Deviations from L1, divisions	Established interval of relative L2=230, divisions	Deviations from L2, divisions
1	2	3	4	5
1 2 3 4 5
A average

5.1.2.1.5. Repeat the above-described procedure (see items 5.1.2.1.2 – 5.1.2.1.3) five times with the interval length equal to 230 divisions.

5.1.2.1.6. The results in the course of investigation should be put down in column 4.

5.1.2.2. Working up of the results

5.1.2.2.1. With the help of figures of column 3 of table 7 calculate arithmetic mean amount of deviation (A average) by formula:

A1+A2+A3+A4+A5

A average = -------------------------- (7),

h

where: A – absolute value of deviations of intervals,

h – number of procedures (equal to five).

Calculate A average from figures of column 5 by analogy.

5.1.2.2.2. Then calculate arithmetic mean values of given intervals (M average) for columns 2 and 4.

5.1.2.2.3. Then calculate the relative amount of deviation for each range of intervals by formula:

A average

B = --------------- x 100 % (8),

M average

Where: B – relative (percentage) value of deviations for each range of intervals,

A average – arithmetic mean value of deviations of intervals,

M average – arithmetic mean value of given intervals.

5.1.2.2.4. Using the results of previous item calculate a general index of movement production accuracy, i.e. general arithmetic mean amount of deviations (B gen.) from two relative values of deviations for both interval ranges.

5.1.2.3. The interpretation of results

5.1.2.3.1. You can judge about the absolute threshold of sensations by percentage value of deviations of intervals advanced by the examinee. This value is directly proportional to the value of absolute threshold of sensations and it is inversely proportional to the index of absolute sensitivity.

5.1.2.3.2. In order to interpret the index of absolute sensitivity in the motive analyzer you may use the universal diagnostic scale 2.4 of appendix 2.

5.1.2.3.3. Since different kinds of activity may include the movements of different expansion, the diagnosis of the accuracy of movement reproduction may include both the general index of the accuracy of movement reproduction and the indexes of deviations on smaller and bigger intervals.

You should interpret these indexes using a universal diagnostic scale 2.8 of appendix 2.

5.1.2.3.4. Besides, you may use average figures, received as a result of sampling of experts of appropriate profiles as normative indexes for different kinds of activity.
