Method of determining falsity of transmitted information on dynamics of parameters of person/s nonverbal behaviour
SUBSTANCE: invention relates to field of cognitive psychology and psychophysiology and can be used for establishment of reliability of content of information transmitted by person in intellectual infocommunication systems, as well as in carrying out office investigations. Structured interview, which includes blocks of questions of neutral and control character, with registration of parameters of nonverbal person's behaviour in the process of answering the questions is carried out. After that, analysis of nonverbal bahaviour dynamics is carried out with identification of its most informative parameters, grouped on the basis of factor analysis into the group of vegetative responses, group of mimic responses, group of pantomimic responses; identification of tendency of changes for each parameter and/or group of parameters, characteristic of the tested person, is performed. After that, parameters of nonverbal person's behaviour in the process of communicative interaction are registered by means of infocummunication system, and used to make conclusion about falsity/validity of transmitted information by comparison of obtained response with response to questions of neutral and/or controlled units of questions, registered in the process of structured interview.
EFFECT: method makes it possible to increase efficiency in determination of falsity of transmitted information in the process of communicative interaction of subscribers by means of infocommunication system.
The invention relates to the field of cognitive psychology and psychophysiology and can be used to establish the reliability of the content transmitted by the person information in intelligent information and communication systems as well as conducting internal investigations.
Intelligence (the combination of transmission and processing of information at different levels of representation) information and communication systems must be established at the early stages of their life cycle and one of the functions to implement the possibility to determine the validity (truth/falsity) of the transmitted information. Despite the constant need to establish the objective truth, at the moment there is no reliable way to implement the specified function.
Currently, to solve the problem of the definition of negative messages is primarily used instrumental method of diagnosis of a polygraph (lie detector). Under this method of false inform the person of the information is judged based on the character of changes in psychophysiological reactions. Despite the popularity of this method, there are a number of conditions that severely limits the possibility of its use in practice. In particular, the use of the polygraph as a contact method is possible only subject to fulfillment of certain requirements of the rd on the organization of space research (comfortable temperature, optimal humidity, noise etc) and personal (the presence of voluntary consent to the study, the lack of somatic diseases, mental disorders, etc.) [fry O. Detection of deception // TRANS. from English. - SPb.: Prime-Eurosac. - 2005. - 320 S., Grozeva IV Formally dynamic and stylistic features of individuality as factors likely instrumental detection of concealed information. Abstract. Kida. the course of studies. Sciences. M: 2006. - 22 S.].
All this greatly reduces the possibility of the use of the polygraph in the interests of personnel work, screening inspections and investigations. In addition methodically almost impossible the use of the polygraph in the process of communicative interaction between subscribers through information and communication systems.
The known method (see RF patent №2099009)that provides mental health assessment, which consists in determining in the subject the combination of features of changes of physiological functions at fixed intervals and the subsequent comparison with the characteristics of the reference States of the psyche, which samples the properties of the individual. The share of the representation properties of the test in the standards and the degree of their manifestation judge the characteristic mental state at the current time. The parameters are compared with p the corresponding indexes of mentally healthy people and those with typical mental disorders, the corresponding standards of adaptability, and then determine the severity assessment of the mental state of the examinee by the share of representation in it of each property.
The disadvantage of this method is the impossibility of its use to establish the falsity of the reported information, as well as the need to define reference conditions psyche that makes the method is subjective and formal, since strict classification of States is impossible on the basis of control of only a few parameters.
Known non-contact control method of psycho-physical reaction (patent RF №2216269), which consists in fixing the psychophysical response of the person on the Desk varying electromagnetic field in the process of verbal and nonverbal communication. According to the method of measuring the resonance frequency shift of the oscillating circuit of the generator of electrical oscillations, made with continuous frequency tuning by placing at a distance of 20-50 cm from the subject of the piezosensor included in the resonant circuit frequency generator. And measure this shift when changing mental and physical state of the examinee stimulated verbal impact, which creates a positive or negative set, of psychophysical reactions are judged according to the values and character of the resonance frequency shift.
The disadvantage of this method is the necessity of using an instrument complex and stimulating verbal impact, which makes it impossible for its application in information and communication systems in relation to the participants of the communicative process (subscribers).
Known way to assess mental and physical condition of man, as well as identifying the degree of sincerity of the answers of subjects using noninvasive monitoring of parameters of eye movement test (patent RF №2337607). This method includes registering the psychophysical response of the oculomotor system in the process of verbal communication. In the research process is recorded videooculography, as criteria to choose the parameters videooculography: pupil diameter, the area of the shape built from points of maximum deflection of the center of the eye visible from middle position, and the number of instruments used. Based on the analysis videooculography determine the answers, in which there has been a change of parameters compared with the control values obtained with known truthful responses, the data and determine the answers, in which there has been an increase in the number of acts blink and square shape, and determine the change in diameter of the pupil, the data and determine the response with the highest to the quantitative difference in criteria between the truth and the alleged false make a conclusion about the emotional psychophysical excitation, which may be due to the fact of concealment or distortion of information.
However, this method is a contact and requires the consent of the person against whom it is to be used, special equipment (videooculography), as well as compliance with certain conditions, necessary for the conduct of research procedures, which makes its application in communication subscribers difficult.
There is a method of assessing the sincerity of the insincerity of the speaker (RF patent No. 2293518), lies in the triple assessment of a number of emotional and psychological properties and States of the speaker by a group of expert observers on the same piece of video of the test duration not less than 40-60 C. a Group of experts and observers must be at least 10 people. The main criterion for selection of expert observers is the fact that each of them great emotional hearing.
Experts should know the basics of expressive movements in volume, at least, popular publications (Glasenberg and Gcamera. To read a person like a book. M., 1990; A. Pease. The body language. N.Novgorod, 1992 and others). Conclusion about the sincerity or insincerity of the speaker is based on the compliance rate of auditory and visual assessments of sparks is nasty and insincerity, based on the degree of compliance with the intonation with the whole range of expressive movements (facial expressions, posture, gestures). Assessment of emotional and psychological properties and conditions is carried out in three stages: 1) assessment of the speaker's voice when the off signal of his video, on the basis of the intonation-timbre, tempo-rhythm, gromkosti the speaker's voice and their changes over time; 2) evaluation of the video image of the speaker when the sound of his voice, based on the observation of facial expressions, posture and gestures of the speaker and their changes over time; 3) evaluation of audio video speaker. At all stages of the survey, the speaker's assessment of sincerity and insincerity give according to their degree of severity according to the method of psychological scaling on a scale or other scales, and in combination with other semantically (i.e. the meaning) opposite the psychological qualities and attitudes of the speaker, including equal or similar value sincerity and insincerity properties and possible state of the speaker, namely: sincerity-insincerity, Frank-stealth, credibility is no longer tenable, sincerity-craftiness, generally at least 3, 4 pairs in the same sincere-insincere properties and States of the speaker. The compliance rate of audio is s and visual assessments of the speaker is determined by the results of the mean scores for the group of expert observers by calculating the rank correlation coefficient for the Coefficient by comparing the two series of average assessments all the emotional and psychological properties and States of the speaker, received on the first and second stages of the survey. The calculated value of the correlation coefficient by Spearman and take the value of the coefficient of compliance with auditory and visual estimates of non-verbal behavior of the speaker and according to the main idea of the method is a psychophysiological measure of the sincerity of the speaker.
However, this method is not practically suitable for solving the problem of determining the falsity of (the truth of) the transmitted information, since its implementation requires a team of experts comprising not less than 10 people, which are:
1) should be included in the process of communicative interaction between two subscribers, leading, as a rule, the private conversation;
2) can't do definitely categorical conclusion, since the method does not require the existence of expert observers of the special skills and knowledge relating to the behaviors of people in situations of saying false information.
In addition, the assessment of the sincerity of insincerity is based on the perceived emotional properties and States that the method gives a high degree of subjectivity. This method does not allow to identify the individual characteristics of nonverbal behavior individual examinee that C is acetelyne reduces the reliability of the results.
In addition, compliance with all requirements deprives the way of efficiency and imposes limitations on the conditions of its application.
Known automatic way analysis of human behavior (patent RF №2292839)containing the stage at which carry out one or more measurements or observations of a person, characterized in that it further comprises the steps on which encode the measurement or observation with the formation of multiple channels, and then analyze the channels using the technology of automatic machine classification to display information related to human psychology, with the technology of automatic machine classification includes methods of artificial intelligence or statistical methods. The method involves a device for automatic analysis of human behavior, containing the discovery tool to perform one or more measurements or observations of a man. The device is characterized in that it further comprises encoder means for encoding measurements or observations with the formation of multiple channels, and automatic machine classification made with the possibility of analysis channels and output information related to human psychology, and the automatic machine classification with the contains a tool of artificial intelligence, which may include artificial neural network, genetic algorithm, decision tree, fuzzy logic, symbolic rules, machine learning and intelligence in other species. You can use the automatic machine classification of other types, such as statistical classification. Statistical classification may contain a microprocessor made with the possibility of a software implementation of statistical methods.
The disadvantage of this method is the need to use specialized equipment, providing some inconvenience to subscribers and requires voluntary consent to its use (by analogy with polygraph).
The closest to the technical nature of the claimed method and selected as a prototype is a method of diagnosis of reported false information on the basis of a structured interview (patent RU 2415645), namely, that a structured interview consists of the following blocks of questions: neutral, control and verification of the nature of the answers to the issues register settings nonverbal conduct of a person, then carry out a study of the dynamics of non-verbal behaviour with identification of the most informative parameters, grouped on the basis of f ktorego analysis in a group of autonomic responses, group facial reactions, group pantomimic reactions, the detection characteristic of the investigated person trends for each parameter or group of parameters, which make the conclusion false/true discourse by comparing the reactions of the test block with the response to the questions neutral and/or control blocks of questions.
Prototype method is the diagnosis of reported false information on the dynamics of parameters of non-verbal human behavior specialist directly in the process of conducting a structured interview. Direct use of the prototype method in the process of communicative interaction between subscribers through information and communication systems is not possible because it is impossible to determine trends in the response of the person for each parameter its nonverbal behavior.
It is possible to analysis by a specialist (expert) audio and video communicative act with further divide it up into neutral, the control and test blocks and the use of the prototype method for formulating conclusion falsity/truth of the reported information. However, this option would use the prototype method:
1) violates the privacy of the conversation (the content of the conversation becomes of the local expert);
2) is highly subjective (expert-psychologist without knowledge of subject areas of conversation of the subscribers have to structure it);
3) has a low efficiency (the output of falsity/truth sent messages can only be done after a communicative act and its analysis by a specialist).
The objective of the invention is to develop a method to determine the falsity of the transmitted information on the dynamics of the parameters of non-verbal human behavior, allowing to increase the efficiency of such a determination in the process of communicative interaction between subscribers through ICT systems.
In the proposed method, this task is solved in that in the method of determining the falsity of the transmitted information on the dynamics of the parameters of non-verbal human behavior, in which the study of the dynamics of non-verbal behaviour with identification of the most informative parameters, grouped on the basis of factor analysis in the group of autonomic responses, group, facial reactions, group pantomimic reactions, the detection characteristic of the investigated person trends for each parameter or group of parameters, additionally carry out a structured interview, which includes two sets of questions: the neutral and control nature, PR is that when the answers to these questions, register settings nonverbal conduct of a person, and then carry out a study of the dynamics of non-verbal behaviour. After identifying characteristic for the investigated person trends for each parameter and/or group settings register settings nonverbal behavior of subscribers in the process of communicative interaction through information and communication system, and then conclude false (truth) of the transmitted information by comparing the reactions registered in the process of communicative interaction with the response to the questions neutral and/or control blocks of questions, registered in the structured interview process.
A new set of essential features allows you to achieve the technical result due to:
1) define the parameters of non-verbal human behavior, identify the most informative of them and the dynamics of their changes during the structured interview, in accordance with the individual characteristics of the person;
2) then determine the falsity of (the truth of) the information transmitted in the process of communicative interaction between subscribers through information and communication system on the basis of comparing the recorded reaction to the reaction to neutral and the control blocks of the structured interview questions.
Diagnosis lies on the parameters of verballing behavior represents one of the most promising directions in the field of theoretical and applied psychology. The prospects of this direction is proved by the results of scientific research (Zuckerman, Ekman, Friesen, fry, Hofer, Mehrabian, the regions ' Tikhonov and others), the accuracy and objectivity of the description of the patent No. 2415645 (prototype method), and the implementation implies the existence of methodological support identify and confirm the most informative parameters and response, typical for any individual.
The analysis of the level of technology has allowed to establish that the analogues, characterized by a set of characteristics is identical for all features of the claimed method to determine the falsity of the transmitted information on the dynamics of the parameters of non-verbal human behavior, no. Therefore, the claimed invention meets the condition of patentability "novelty".
Search results known solutions in this and related areas of technology in order to identify characteristics that match the distinctive features of the prototype of the features of the declared object, showed that they do not follow explicitly from the prior art. The prior art also revealed no known effect provided the essential features of the claimed invention transformations on the achievement of the technical result. Therefore, the claimed invention meets the condition of patentees the activity of "inventive step".
The implementation of the inventive method consists in the following.
Having learned the identity of the subscriber (subscribers) based on the analysis of different sources of information (materials personal Affairs, service characteristics, sheets for accounting personnel and so on), evaluated the feasibility study based on a structured interview, developed the program with the subsequent implementation and evaluation of the results directly during the procedure, as well as by mathematical processing of the results by an expert (expert) using any reliable way of processing information.
Documenting procedures structured interview is based on audio and video.
The structure of the interview consists of fragments (tests), which are standardized according to the categories used blocks of different issues (neutral and control). Neutral questions do not relate to the audited subject, control and reflect the discussion of the problems of socially unapproved behavior.
For the analysis of nonverbal behavior are 17 indicators that comprise three main groups of information (table. 1).
|The first group (autonomic response)||1) the number of movements of the tongue (licking lips);||1|
|2) the amount of redness (hyperemia);||2|
|3) the number of slatinany saliva;||3|
|4) the number of blinks;||4|
|5) number of deep breaths.||5|
|The second group (facial reaction)||1) the number of smiles;||6|
|2) the number of movements of facial muscles in the forehead and eyebrows;||7|
|3) the number of movements of the nose (contraction-expansion of the nostrils);||8|
|4) the number of movements of the lips.||9|
|The third group (pantomimic reaction)||1) the number of head movements;||10|
|2) the number of movements of the shoulders;||11|
|3) the number of movements of the torso;||12|
|4) the number of gestures, illustrations;||13|
|5) the number of gestures, manipulations;||14|
|6) the number of movements of the hands and fingers;||15|
|7) the number of movements of the legs and feet;||16|
|8) the frequency of change of the posture.||17|
The inventive method involves two main variants of the results:
1) on the basis of the number of reactions in absolute units recorded in the minutes, which are populated during a structured interview. This approach allows to calculate the average number of responses for each option nonverbal behavior per minute with respect to a particular set of issues and to compare the reactions between the units;
2) allows to estimate not only the number of reactions, but also their severity during the interview, which uses a system of points (maximum score reflects the greatest intensity response with the trend).
Both ways is the tsya mandatory, if for collecting non-verbal signs of human behavior used technical devices and conducted machining results.
The trend in the response is determined on the basis of benchmarking neutral topics with the parameters of the control unit issues. If the response to test questions exceeds the index of neutral topics, the reaction is increased in the testing unit issues control issues. If the response in the control unit issues less than in the neutral block, then Vice versa.
The accuracy and efficiency of this approach is confirmed by the correlation analysis, the results of which are presented in the description of the prototype method. The following General trends in the dynamics of parameters of non-verbal behavior of subjects in a situation pronounce them false information in comparison with the situation of the utterance of the true information: (a) reducing the number of head movements (83.3% of cases on average 25.8%); b) reducing the number of movements of the legs and feet (66,70% of cases on average 34,08%); C) increasing the number of smiles (58.3% of cases on average 114,47%); d) increasing the number of movements of the nose (widening/narrowing of the nostrils) (58.3% of cases on average 195,89%); d) the increase in the number of slatinany (58.3% of cases 90,86%); d) increasing the amount the government of blinking (50% of cases on average to 2.29%). In other cases, the direction of the dynamics of the analyzed parameters nonverbal behavior is individual and may vary as upwards and downwards.
Factor analysis that reflects the assessment of community for each variable, the squared multiple correlation of this variable with other variables, allowed us to identify three factors based on the hierarchical method of combining received data (table. 2).
|The results of factor analysis|
|Factor 2||Factor 3|
The distribution of parameters within the selected factors (table 2) are characterized by stability and preserved at all stages of the structured interview. These factors reflect exclusively non-verbal behavior and are treated as basic, that does not preclude inclusion in the way of some additional parameters with selection on the basis of additional factors.
As additional factors can be used, and other parameters, for example related to the evaluation of parametric indices, the OTP is concerned with changes in speech, the electrical activity of the heart, brain, other organs and systems of man. The main criterion for their inclusion is changing their settings in the canons of psychophysiology, which allows to make a conclusion about the truth (falsity) transmit the analyzed information.
A structured interview, usually conducted in the process of preparing and screening checks during the hiring, appointment to higher positions, the professional fitness of the subjects. After these checks, the results can be accumulated and handled accordingly to identify characteristic for the investigated person trends for each parameter or group of parameters nonverbal behavior.
Directly in the process of communicative action (session, conversation) through information and communication system register settings nonverbal behavior (table 1) interested party (subscribers). Then the conclusion is false (truth) transmitted during said act information by comparing the received response (parameter values nonverbal behavior) with reaction (trend changes for each parameter or group of parameters nonverbal behavior), registered inthe structured interview.
Preliminary analysis of nonverbal behavior directly in the process of communicative interaction between the subscribers, the final one is done based on the subsequent mathematical processing of the received audio and video.
The claimed method of determining the falsity of the transmitted information on the dynamics of the parameters of non-verbal human behavior speeds up this definition in the process of communicative interaction between subscribers through information and communication system. To prove the claimed technical result is the following experimental studies.
Study subject record a video-conferencing session between users # 1 and # 2 with a duration of about 87 C. it was Necessary to establish the truth (falsity) of data provided by the subscriber No. 2.
Why was investigated audiovideoking structured interview, obtained in the process of conducting a screening test with the specified subscriber when his employment. The study was based on the implementations of the neutral fragment of conversation, followed by review questions. The topic of this conversation were selected taking into account individual peculiarities of an individual subscriber # 2 and were not associated with subsequent activities (subject to RA the contract).
As a result of this research according to the claimed method were identified characteristic for the studied subscriber trends for each parameter or group of parameters nonverbal behavior.
After this, a study was conducted record of a communicative act (videoconference session), which was focused on the identification of false (truth) information communicated by the subscriber No. 2 (approximately 47).
Conclusions about the falsity of the reported information was based on the mapping parameters nonverbal behavior issues a control unit structured interview and a communicative act, which is implemented by the subscriber No. 2 (PL. 3).
|Average evaluation of the nonverbal behavior of the subscriber No. 2|
|Parameters nonverbal behavior||Blocks of structured interview questions||The communicative act by the subscriber No. 2|

|2. In bold are the most informative indicators indicating the falsity transmitted by the subscriber No. 2 information.|
From the analysis of the research results presented in table. 3, it is seen that the speaking of false information to the subscriber No. 2 characterized by the following dynamics of nonverbal behavior in the first group of signs: 1) increasing the number of movements of the tongue (licking lips); 2) increasing the amount of redness (hyperemia); 3) reducing the number of blinks; 4) increase the number of deep breaths.
In the second group when the utterance of false information to the subscriber No. 2 characterized by the following dynamics of parameters of non-verbal behaviour: 1) reducing the number of movements of facial muscles in the forehead and eyebrows; 2) increasing the number of movements of the lips.
In the third group are the following change of parameters of non-verbal behaviour caller No. 2: 1) increasing the number of movements of the body; 2) reduction in the number of gestures-manipulation; 3) reduction in the number of movements of the hands and fingers; 4) learning is their change of posture.
Sustainable direction changes of the analyzed parameters in the process of communicative interaction in comparison with the response to the questions neutral and control blocks in the structured interviews indicates insincerity subscriber No. 2 during the conversation with the caller No. 1.
A similar result was obtained with regard to automatic processing of record of the certificate of communicative interaction between these two subscribers (videoconference session) known technical and algorithmic means, but in other (related to the instrumental error) values of non-verbal behaviour. However, the obtained result allows the use of the claimed method in real time - in the process of communicative interaction between subscribers through information and communication system. This application allows to increase the efficiency of determining the falsity of the transmitted information on the dynamics of the parameters of non-verbal human behavior in comparison with the method of the prototype.
How to determine the falsity of the transmitted information on the dynamics of the parameters of non-verbal human behavior, namely, that carry out the study of the dynamics of non-verbal behaviour with identification of the most informative parameters, grouped on the basis of factor an the Lisa group vegetative reactions, group facial reactions, group pantomimic reactions, the detection characteristic of the investigated person trends for each parameter or group of parameters, wherein conducting a structured interview, which includes two sets of questions: neutral and supervision, while the answers to these questions, register settings nonverbal conduct of a person, and then carry out a study of the dynamics of non-verbal behaviour, and after identifying characteristic for the investigated person trends for each parameter and/or group settings register settings of his non-verbal behaviour in the process of communicative interaction through information and communication system, and then conclude false (the truth of) the transmitted information by comparing the reactions registered in the process of communicative interaction with the response to the questions neutral and/or control blocks of questions registered during the structured interview.

SUBSTANCE: invention relates to field of medicine, in particular to psychiatry and can be applied for psychopathological estimation of psychic state of infants and preschool children. To perform psychopathological estimation of psychic state of infants and preschool children estimation of child's psychic and neurological state is performed. As symptoms of patient's psychic state estimated are state of sphere of cognitive functions: play, thinking, memory, speech; state of sphere of psychic activity: aim-oriented behaviour, volitional desires, motives, workability; state of emotional sphere, sphere of attraction, sensor perception, impairment of perception: acousma, photopsia, hallucinations, self-consciousness and state of sphere of social behaviour: communication disorders, autistic symptom, social skills. As symptoms of patient's neurological state, state of sphere of neurological signs, motor activity and state of initial vegetative tome - vagotonia and sympaticotonia are estimated. Estimation of each symptom is performed in points from 0 to 7. Total value of average point of identified symptoms for each sphere, reflecting severity of patient's psychic and neurological state, is calculated. Average points are summed up for each sphere and severity of state is determined in accordance with determined values, namely if the total sum of average points is from 0 to 9, psychic state is estimated as child's practical health; if value is from 10 to 18 points, presence of boundary psychic disorders is estimated, from 19 to 27 points - as mild severity of psychic disorders, from 28 to 36 - as moderate severity, from 37 to 45 points - as medium, from 46 to 54 - as severe, from 55 to 63 points, psychic state is estimated as extremely severe degree of psychic disorders.
EFFECT: method makes it possible to increase accuracy of psychic state of infants and preschool children due to application of differential and diagnostic criteria of symptoms of psychic disorders.
SUBSTANCE: invention relates to field of medicine and is intended for determination of time of person's response to object which is moving away from them. Closed limiting contour, inside which test object of analogous configuration is concentrically placed, is shown on videomonitor screen. Test object is magnified in accordance with specified rate, with imitation of its movement towards the tested person. At the moment of supposed coincidence if dimensions of limiting closed contour and test object the tested person stops magnification of test object diameter by pressing "Stop" button.

SUBSTANCE: one should test a patient by seven scales: frequency, duration, intensity, sensor perception of pain, emotional attitude towards pain, neurotization level, adaptation capacity level to evaluate the results obtained by the scales mentioned from 0 to 6 points. Moreover, the scales for sensor perception and emotional attitude, the levels of neurotization and adaptation capacity should be evaluated in accordance to the Tables given in description. Additionally, one should, compare the degree of psychogenic constituent of pain according to chromatic choice made by a patient depending upon, at least, three choices of pain intensity: "pain during testing", "no pain", "severe pain" in accordance to the Tables given in description. Then, according to the results of testing one should evaluate the degree of patient's pain feelings both quantitatively and qualitatively. Moreover, by the scale of frequency the appearance of pain should be evaluated from "pain appeared once during several days or rarely" to "constant pain". By the scale of duration pain should be evaluated from "momentary pain" to "constant pain". By the scale of intensity the pain should be evaluated from "very weak pain" to "unbearable pain". By the scale of neurotization level one should take into account basic behavioral factors, such as anxiety, emotional lability, aggression, depression, psychogenia, hypochondria. The present innovation enables to increase significance in evaluating pain achieved due to broadened verbal description of patient's pain feelings.
EFFECT: higher accuracy of evaluation.

SUBSTANCE: the method deals with correcting neurological and psychopathological disorders with anxiety-phobic symptomatics due to individual trainings. The method includes evaluation of body reaction to stimulating signals, seances of individual training performed due to the impact of two quasiantipodal stimulating signals of similar physical modality applied in time of sporadic character, and as a signal one should present biological feedback for the altered value of physiological parameter adequately reflecting body reaction to the impact of stimulating signal. At the first stage of training it is necessary to achieve body adaptation to the impact of quasiantipodal stimulating signals, at the second stage it is necessary to obtain conditional reflex for one out of stimulating signals, for this purpose one should accompany this stimulating signal with discomfort impact, during the third stage, finally, due to volitional efforts one should suppress body reaction to stimulating signal. The devise suggested contains successively connected a transformer of physiological parameter into electric signal and a bioamplifier, an analysis and control block with a connected block to present the signals of biological feedback, a block for presenting discomfort impact, an indication block and that of forming and presenting quasiantipodal stimulating signals. The innovation enables to have skills to control one's emotions, decrease sensitivity threshold to environmental impacts and learn to how behave during stress situations.
EFFECT: higher efficiency of training.

SUBSTANCE: method involves measuring patient weight, recording age and sex of the patient. The patient is positioned in front of computer display unit. The data are inputted into the computer comprising software containing a program for estimating organism organs and systems condition. The following organs are detected. Lung, spleen, heart, kidneys, liver are proved for having deviations from norm with negative sign towards hypofunction or with positive sign towards hyperfunction. The data are displayed with the program on the screen as a table with reference and current values being shown in relative units with plus or minus sign. Canal states are estimated from detected organs being under maximum stress on the basis of infogram: lung canal P, spleen - canal RP, heart - canal C, kidneys - canal R, liver - canal F. When estimating organ state with deviation having plus sign, that means hyperfunction, canal state is estimated as having energy excess. When organ state deviation has plus sign, that means hyperfunction, canal state is estimated as having lack of energy. Eye diseases are diagnosed from state of organs and canals of P, RP, C, R and F. Hyperfunction in organ and excess in canal being available, initial ophthalmic disease stage is diagnosed. Hypofunction in organ and deficit in canal being available, chronic ophthalmic disease stage is diagnosed.
EFFECT: wide range of functional applications.

SUBSTANCE: method involves showing sequence of two luminous pulses of 10 ms duration separated by 150 ms long pause. The pulses are repeated in constant 1.5 s long interval. Pause duration between two luminous pulses is reduced at the first measurement stage at constant speed of 20ms/s until a testee fixes fusion of two luminous pulses into single one in subjective assessment mode. Pause duration between two luminous pulses is increased at the second measurement stage with given constant step of 0.4 ms until the testee identifies the moment of subjective perception of two luminous pulses separation. Pause duration is reduced in discrete mode with given constant 0.1 ms long step at the third measurement stage until the testee identifies the moment of subjective perception of two luminous pulses fusion into single one. Human vision system persistence time is determined to be equal to pause duration between two luminous pulses when subjective fusion into single pulse takes place at the third measurement stage.
EFFECT: high accuracy in determining human vision system persistence time.
