Description

 The invention relates to the field of psychophysiology and can be used to test the level of knowledge in educational systems, when assessing professional abilities and the like psychophysiological studies using testing.

 A method is known from the prior art for assessing the level of training of students by conducting rating testing, including assigning weighting factors to each test question, comparing answers and showing results, in which the weighting factors of testing questions additionally verify the validity and correctness of the answer to the test question (RU 2145422 C1, G 09 D 7/02, 02/10/2000).

 The disadvantage of this method is the lack of control of the psychophysiological state of students in the testing process.

 There is also known a method of professional selection of operators by registering physiological parameters before and at the time of the intellectual load, followed by determining the level of performance compared to the data obtained, while the physiological parameters are recorded blood pressure and electroencephalogram, and the intellectual load is fed through the sound channel in steps with increasing complexity.

 This method allows you to assess the level of mental tension of the subject, taking into account the cycle and difficulty of the tasks to be solved, however, the type of recorded physiological parameters limits the possibility of its use to determine the emotional and stressful state and the correctness of answers to questions in the testing process.

 Closest to the invention in terms of technical nature and the achieved result is a method of determining professional suitability by assessing emotional and stressful tension, including responses to questions of various significance, while the assessment is carried out according to the dynamics of the skin-galvanic reaction to verified significant and insignificant questions (RU 2068653 C1, A 61 B 5/16, 11/10/96).

 However, the method of recording the skin-galvanic reaction does not fully reflect the objective psychophysiological state of the subject when answering questions of emotional and stressful significance.

 The invention is aimed at improving the efficiency and reliability of determining the level of professional suitability by expanding the number of controlled physiological parameters.

 The solution to this problem is provided by the fact that in the method of determining professional suitability, including recording a skin-galvanic reaction to questions of various significance and assessing emotional and stress tension during testing by the dynamics of indicators, according to the invention additionally records the frequency of chest respiration, the frequency of diaphragmatic respiration, the frequency heart rate, motor response and voice response, with each test containing at least When groups of different significance issues and suitability level is determined by the set of relevant questions, the answers to which cause burst - the deviation of the detected indices from the mean value corresponding to the least significant issues, more than 50%.

 In addition, at least three different tests are formed to identify motivation for choosing a profession, personal character traits - leadership, criminal propensity - criminogenicity, and each test includes neutral, test and control questions in terms of significance.

 The use of the claimed method of printing registration of various physiological parameters in combination with the auditory presentation of variously oriented tests, including three groups of questions of importance (neutral, verification and control), provides a high degree of identification of individual abilities and inclinations of the subject, which increases the didactic capabilities of psychophysiological studies in assessing professional suitability.

 In Fig.1 shows a block diagram of a device for carrying out the invention, and in Fig. 2 presents the results of data processing.

 The device is a 6-channel contact polygraph, which contains a sensor 1 for skin-galvanic reaction (RAG), a sensor 2 for chest breathing (DG), a sensor 3 for diaphragmatic breathing (DD), a photoplethysmographic sensor 4 for heart rate (PPG), and a sensor 5 for motor activity (YES) and voice response sensor 6 (microphone) (GR), amplifier unit 7 (U), switch 8 (K), analog-to-digital converter 9 (ADC), program unit 10 — computer microprocessor (PB), display 11 (D).

 The method for determining professional suitability is implemented as follows.

 Corresponding sensors are placed on different parts of the subject’s body for recording physiological parameters, while 1 RAG sensor in the form of two electrodes is fixed on the index and ring fingers of one of the hands, tensometric sensors 2 DG and 3 DD are mounted on the chest and in the diaphragm, a photoplethysmographic sensor 4 FIGs are fixed on the middle finger of the hand, a 5 YES strain gauge is placed on a chair under the test subject, and 6 GR sensor is fixed on the chest next to sensor 2.

 In the process of testing, under the control of a polygraph, a series of auditory tests are presented to the test subject, compiled to assess individual abilities and inclinations according to various criteria that determine the motivation for choosing a profession, personal character traits - leadership, level of criminogenicity (penchant for crime), alcohol, drugs, etc. . P.). Moreover, each test that contains questions of various importance: neutral, verification, control, is presented 3-4 times.

 The physiological parameters registered by the sensors 1,2,3,4,5,6 are transmitted through the amplifier unit 7, the switch 8 and processed in the program unit 10 - the microprocessor, and the received information is displayed on the display 11 in the form of curves - physical fluctuations of the skin-galvanic response , the frequency of chest and diaphragmatic breathing, heart rate (pulse), the reaction of motor activity and voice response, histograms or tables.

), соответствующего менее значимым вопросам, более чем на 50%, что свидетельствует о повышенной стрессовой и эмоциональной напряженности и позволяет оценивать уровень профессиональной пригодности и правдивости ответов.At the same time, analyzing the dynamics and nature of the change in the indicators of physiological parameters, a set of significant (test and control) questions is determined, the answers to which cause a sharp surge - the deviation of the recorded parameters (for example, amplitude A _i ) from the average value (for example, amplitude

), corresponding to less significant questions, by more than 50%, which indicates increased stress and emotional tension and allows us to assess the level of professional suitability and truthfulness of answers.

 Example 1

), что может свидетельствовать о несамостоятельности выбора профессии, об отсутствии интереса к ней и т.п.Test for determining the motivation for choosing the profession of an applicant when entering a higher educational institution:
1. What is your name ...? {Neutral}
2. Have you chosen the profession of lawyer of your own free will? {control}
3. Do you strive to become a better lawyer? {test}
4. In your opinion, the legal profession gives you power over other people? {test}
5. Are you attracted to pay in your chosen profession? {test}

In FIG. Figure 2 shows a fragment of the polygram, from which it follows that the significant question No. 6 caused emotional stress (as can be judged by the sharp increase in the amplitude A _{i of the} curves of the registered physiological parameters compared to the average value

), which may indicate the non-independence of the choice of profession, the lack of interest in it, etc.

11. Could you have done something to discredit your opponent in the eyes of other people? {control}
12. In your opinion, are all means good at achieving success? (control)
Example 3

1. Do you live in Moscow? {neutral}
2. Are you addicted to gambling? {control}
3. Have you ever committed administrative offenses? {control}
4. Have you ever been detained by the police? {control}

9. Have you ever taken medications without a doctor's prescription? {control}
10. Have you ever bought drugs? {control}
11. Do you keep drugs in your possession? {test}
Testing according to examples NN 2-3 did not reveal sharp deviations of the curves of physiological parameters from the average value.
