5.4.5. Some possible ways of practical use of methods and results of the diagnostics

Taking into account the vital importance of movement coordination for a great number of activities you should use the diagnostic data:

5.4.5.1. In the process of professional selection. In this case it is reasonable to compare the results of examinee’s diagnostics with the appropriate parameters of a specialist’s model.

5.4.5.2. In the process of industrial training when developing motive functions, and also in the process of individual activity style formation.

5.4.5.3. In the process of treatment of motive functions damage as a means of feedback.

5.4.5.4. In sports and physical education.

§ 5. The diagnostics of leading hand

5.5.1. General description

According to the criterion of leading hand all the people can be divided into right-handed, left-handed and ambidextrous.

The widely spread opinions concerning the right-left handedness have two inaccuracies. First of all, the opinion that every man knows exactly what his leading hand is does not correspond to reality. As numerous foreign and domestic research show, many people are not conscious that they are re-taught (genetic) left-handed people, because their right hand is more developed under the influence of their family or school education. Such people are mistaken considering themselves to be right-handed people and operating against their own genetic code. They can’t fully develop as personalities and, consequently, their activity is not effective.

Secondly, another opinion, that the number of right-handed people is much more than the number of left-handed people in the population, is not correct either. This inaccuracy is caused by the above-mentioned mistakes concerning the re-taught left-handers and it was revealed in the course of different foreign and domestic (including those held in our country) investigations. It was proved that the number of real or re-taught left-handed people makes 40-45 per cent of the whole number of people.

Traditional tests for the diagnostics of right-left-handedness (such as “Napoleon’s pose”, “applause”, twiddling the fingers into a “latch” and others) give a certain idea about this. However, they do not allow to reveal ambidextrous people. And do not give any opportunity to define the position of the examinee on the “left-handed person – right-handed person” continuum, i.e. they do not meet the requirements of system diagnostics.

That is why we suggested the method of leading hand investigation that meets the requirements of system diagnostics. The method is carried out on the device ATS-6 with the help of special device – coordinationmeter.

5.5.2. The procedure of diagnostics

5.5.2.1. Adjust the coordinationmeter bar so that the scale containing divisions could be easily seen. Put the romper-suits into initial position, into “0”.

5.5.2.2. Prepare the report of the diagnostics having filled in the columns 1 and 2 of table 17. Put down the serial numbers of the thirteen procedures of the diagnostics into column 1. And put down the values of intervals that you will set to your examinee (within the range from 50 to 90 divisions) into column 2.

Table 17 – the report of leading hand diagnostics

№ of procedure	The interval set by the examinator, divisions	The interval established by the examinee, divisions		Reproduction mistake, divisions
		Left hand	Right hand	Left hand	Right hand
1	2	3	4	5	6

5.5.2.3. The examinee clasps the right romper-suit by the thumb and index finger of his right hand and he clasps the left romper-suit by the thumb and index finger of his left hand.

5.5.2.4. Then the examinee should remember visually the given interval, i.e. the position of two identical numbers, which are placed on the upper and lower halves of the bar.

5.5.2.5. The examinee closes his eyes and, by memory, quickly moves both of the romper-suits on the given numbers simultaneously. Then he releases the romper-suits and opens his eyes.

5.5.2.6. If the examinee starts to look (to spy), then, after the visual remembering of the given task, you should remove the scale (adjust a “blind bar”). Place the scale back only after the examinee puts his hands aside after the execution of his task.

5.5.2.7. Make the counting of right and left romper-suits readings and put them down into column 3 and 4 of table 17 accordingly.

5.5.2.8. Repeat the procedure described in items 5.5.2.3 – 5.5.2.7 thirteen times, varying the task in accordance with the column 2 of table 17.
