Abstract

FIELD: medicine.

SUBSTANCE: in the process of interactive psycho-physiological testing, questions are presented to the examinee. The physiological parameters of the examinee are recorded, and the psychological component is recorded by measuring the brain electrical conductivity using electrodes applied to the temporal areas, and directly above the ears in areas with no hair in the left and right temples 5 cm from the upper ear edges. The electrical conductivity in the temporal area and the area above ears is constantly measured during the entire time of test questions presentation. By the changes in the electrical conductivity, measured in the temporal area, an increase in the emotional stress of the examinee is judged when presenting the question. By the changes in the electrical conductivity measured above the ears, are images updating in non-volatile memory of the examinee is judged upon question presentation.

EFFECT: method allows to determine the functional nature of psycho-physiological reactions when presenting the questions to the examinee, and the ability to determine whether the person recalls anything when a question is presented, or not, by conducting interactive psycho-physiological testing using electrodes applied to temporal areas and directly above the ears.

Description

The invention relates to medicine, in particular to the field of conducting psychophysiological studies, for example, analysis of psychophysiological reactions of a person, and can be used for medical purposes, functional diagnostics, pedagogy, psychology, judicial practice and forensics.

A polygraph is an electrical device that accurately measures the amplitude and duration of the corresponding psychophysiological reactions of a person in the dynamics of their manifestation. A modern polygraph, as a rule, captures psychophysiological information on at least four functional physiological parameters of the human body (respiration, galvanic skin reaction, cardiovascular activity, physical activity) and is used with a personal computer with appropriate software. The removal and fixation of psychophysiological information is traditionally carried out using contact polygraph sensors through the conversion of electrical signals into digital and graphic forms on a computer screen and subsequent fixation in a digital and reproduced form on paper media. The indicated processes of taking psychophysiological information and its statistical processing are determined by the design features of a particular polygraph, its software and the features of the method used in a specific psychophysiological study using a polygraph. Examples of a classic polygraph are polygraphs "Chris" (http://antev-group.ru/chris.html) and "Reef" (http: //www.antey- group . Ru / reef . Html )

A known method of psychophysiological testing using a classic polygraph, which consists in presenting questions to the test person, recording the physiological parameters of the test person, as well as the psychological component. The physiological parameters are measured using a human skin-galvanic reaction (RAG) sensor, a photoplethysmogram read-out sensor (PPG), a blood pressure (BP) read-out sensor, upper and lower pressure sensors (VDH and NDH) and a motor activity-tremor sensor (TRM). Registration of physiological parameters is carried out during the entire testing time. By changing the parameters relative to the background values, the significance of the question for the test person is judged. To measure the psychological component, use the Kosynka psychological component evaluation module (PS), which is a bandage with four electrodes attached to it. One electrode is placed on the central part of the forehead, two electrodes are placed on the temporal regions and one electrode on the back of the head. Measure the temperature of the frontal lobes and rheoencephalogram (Internet site "Polygraph training online" http://www.polygraph-training.info/).

The electrode applied to the frontal lobes is designed to measure the activity of the cortex of the frontal lobes of the brain, the associative zone of which is involved in updating the images - in short-term memory, as well as in deciding how to respond and how to act at the time of the answer. This electrode is used to determine “self-control” at the beginning and end of testing. The electrode applied to the back of the head is a distribution electrode. One electrode is applied to the right and left temporal areas - about 5 cm forward from the upper edge of the ears. Temporal electrodes are used to record changes in electrical activity (by taking a rheoencephalogram - measuring electrical resistance) in the area of the limbic cortex to determine the change in "internal aggression" during testing. Measurements are carried out twice - at the beginning and at the end of testing.

The known method did not allow to determine the functional nature of psychophysiological reactions, for example, in order to determine at the time of presentation of a question whether a person remembers something or not.

Closest to the proposed one is a method of interactive psychophysiological testing (the “Losev-Miller Mutual Exclusion Method”), which consists of submitting questions to the person being tested, registering the physiological parameters of the person being tested using polygraph sensors, and changing the registered parameters while presenting questions and receiving answers from the tested person makes a judgment about the reaction of the tested person to the relevant questions, and the test questions are constructed in the form of questions types: B1 questions on the first version, B2 questions second version, neutral questions H, the questions on the first and second versions B1 and B2 are mutually exclusive meaning, but equal force, the test CFT constructed in accordance with the concatenation of

where X is the index identifier of the tested person;

O is an underestimated “zero” question;

C - a question that relieves the stress of expectation;

B1 _i - a question according to the first version, where i = 1, 2, ..., n;

B2 _i - a question according to the second version, where i = 1, 2, ..., n;

H is a neutral question;

n is the number of specific circumstances of the event or action;

“:”, “→”, “.” - separators,

moreover, the design of questions is carried out taking into account the phasing of the event under investigation, including only reliable facts or information in the design of questions, excluding speculation or version of the person conducting the test, according to the test results, one of the two mutually exclusive versions prevails and the corresponding status of the tested person is evaluated, while the definition and analysis of psychogenesis is carried out using a polygraph, and the construction of questions of two mutually exclusive versions, indication and processing OF DATA CFT performed using a computer with appropriate software (RU 2531645 C2, publ. 27.10.2014).

This method also does not allow to determine the functional nature of psychophysiological reactions, for example, in order to determine, at the time of presentation of a question, whether a person remembers something or not.

The objective of the invention is to increase the reliability of psychophysiological testing.

The technical result of the invention consists in providing the possibility of determining the functional nature of psychophysiological reactions when presenting a test subject, namely, the ability to determine whether a person remembers something when presenting a question or not.

The technical result is achieved by the method of interactive psychophysiological testing, which consists of presenting the test person with questions, registering the physiological parameters of the test person, and judging the reaction of the tested person to the relevant questions by changing the registered parameters during the presentation of questions and receiving answers from the tested person, which according to the invention as physiological parameters register the psychological component by measuring electrical conductivity of the brain using two electrodes superimposed on the area above the ears, which are placed directly above the ears in areas where there is no hair, and two electrodes superimposed on the temporal areas, which are placed in the left and right temples 5 cm from the upper edges ears, and the measurement of electrical conductivity in the temporal region and in the region above the ears is carried out continuously throughout the entire time of presentation of the test questions, on the change in electrical conductivity, measured in in the juicy area, they are judged about the increase in the emotional stress of the test person when a question is presented, and by changing the electrical conductivity measured in the area above the ears, they are judged about the actualization of images in the long-term memory of the test person when a question is presented.

In addition, a skin-galvanic reaction (RAG) is recorded as a physiological parameter, and in the presence of a simultaneous change in the RGR and electrical conductivity in the region above the ears, the conclusion is made that the images are updated in the long-term memory of the test person upon question.

In addition, respiratory indices are recorded as a physiological parameter, including respiration, and in the presence of a simultaneous change in respiration and electrical conductivity in the temporal region, the conclusion about an increase in the emotional stress of the test person upon presentation of a question is confirmed.

In one case, when registering the simultaneous presence of a change in electrical conductivity, measured in the temporal region and in the region above the ears, a conclusion is made about the actualization of an emotionally significant image in the long-term memory of the tested person.

In another case, when registering the simultaneous presence of a change in electrical conductivity, measured in the temporal region, and the absence of a change in electrical conductivity, measured in the region above the ears, it is concluded that there is an emotional stress in which the images in the long-term memory are not updated.

In the third case, when registering the simultaneous absence of changes in electrical conductivity, measured in the temporal region, and the presence of changes in electrical conductivity, measured in the region above the ears, they conclude that the emotionally significant image is updated in the long-term memory of the tested person.

In addition, in the case of recording changes in electrical conductivity, measured in the region above the ears, when answering the verification question is more than 10% higher than when answering the question of a deliberate lie or a question of a known truthful answer (representative question), they do conclusion about updating the image in the long-term memory of the tested person.

In the case of recording changes in the electrical conductivity, measured in the region above the ears, when answering the verification question is more than 30% lower than when answering the question of a deliberate lie or the question of a deliberately truthful answer (representative question), they conclude that there is no updating the image in the long-term memory of the tested person.

In the case of recording changes in electrical conductivity, measured in the region above the ears, when answering the verification question is less than less than 30%, or equal to or higher than no more than 10%, than when answering a question to a deliberate lie or a representative question, then conclude about the possibility of updating the image or enhanced cognitive activity without updating the image in the long-term memory of the tested person.

In the proposed method, continuously, during the whole time of testing, in addition to physiological parameters, activity indicators (electrical conductivity) of the limbic cerebral cortex (electrodes in the temporal region — “temporal electrodes”) and activity (electrical conductivity) of the temporal cortex (electrodes) are recorded in the area above the ears - “air electrodes”).

The electrical resistance measured by electrodes characterizes the electrical activity of the brain. The activity of the limbic and temporal cortex is constantly determined upon presentation of each question. A change in the activity of the limbic cortex indicates the emotional stress of the test person, and a change in the activity of the temporal cortex indicates the actualization of images in long-term memory. The constant and simultaneous registration of these parameters allows you to determine whether the test person remembers anything during the presentation of the question.

The proposed method gives additional opportunities to the polygraph in combination with other indicators (RAG, FPG, BP, VDH, NDH, TRM) to make a judgment on the increase in brain activity, to clarify the nature of changes in traditional indicators.

The functional nature of psychophysiological reactions has not been reliably determined previously. The proposed method allows you to reliably understand the cause of "significant" reactions. It is impossible to draw a conclusion about any regularity in only one indicator. To do this, two indicators, different in principle of registration, are required. For example, the indicator of activity of the limbic cortex and the indicators of respiration (VDH and NDH) and blood pressure (BP) are three different indicators that are not related by the principle of removal, by which changes in emotional stress can be reliably observed. The temporal cortex activity index and the skin-galvanic reaction index (RAG) are two different indicators that are not connected by the principle of removal, which reliably indicate the processes of updating images in long-term memory.

In forensics, the findings of diagnostic methods of special psychophysiological studies (SPFI) are usually uploaded with a wording about a “significant reaction to a question”, while the proposed method will allow one to obtain more accurate formulations. For example, it is possible to draw conclusions that reactions that are characteristic of actualizing in the memory of the tested “emotionally insignificant images”, or characteristic of actualizing “emotionally significant images”, or characteristic of the emotional significance of reactions for which there are no signs of actualization of images in long-term memory.

The most effective proposed method is, if we use the sequence recommended by the authors for reading questions using the method of zone representative questions (MRLS), which consists in the fact that when testing in each comparison zone, tests based on the control questions method (MKV), the verification and neutral methods questions (MPNV), methods for revealing hidden information (MVSI tests: L. Killer peak voltage test, D. Likken test, search test) or mutual exclusion method (MVI, see RU 2531645 C2) yuchayutsya represent specific issues on which the test events has no reason to hide information (question with a known true answer, causing remembrance of representation of the past experience of the test) and / or questions on deliberate lies.

The following options are possible for the sequence of questions when using the MHRV.

1. The test version used in the investigation of events that were not allocated in time or in space contains control questions, and it is designed in accordance with the concatenation:

2. The test variant used in the investigation of an event highlighted in time or in space, with mutually exclusive direct questions, is constructed in accordance with the concatenation:

3. The test version used in screening and scheduled inspections of personnel is designed in accordance with the concatenation:

4. The test variant used to identify any detailed information contains conditionally neutral and significant questions in one comparison zone, while it is designed in accordance with the concatenation:

5. The test variant used in the search for any detailed information contains many significant questions in one comparison zone; it is constructed in accordance with the concatenation:

In FIG. 2 presents a polygram and a table to it, obtained during testing according to example 2.

In FIG. 3 presents the questions presented during testing according to example 3 on the background of the polygram.

The proposed method of psychophysiological testing was carried out using a classic polygraph complete with sensors KGR, FPG, HELL, VDH, NDH, TRM, as well as using a device that registers KPS signals from the electrodes “Kosynsky”.

Sensors were mounted on the test person in the same manner as in the known testing method. A Scarf was attached to the head, which had two additional electrodes. In this case, two electrodes were placed in the region of the left and right temples about 5 cm from the upper edges of the ears, two electrodes were placed directly above the ears in areas where there was no hair. If there is hair, conductive gel is used to ensure electrical contact. One electrode was placed on the forehead and one on the back of the head, as in the known method.

The test person was asked questions and received answers. During the entire test, the RAG, FPG, blood pressure, VDH, NDH, and TPM indicators were recorded, as well as the KPS indicators of the electrical activity of the limbic cortex (temporal electrodes) and the electrical activity of the temporal cortex (scent electrodes) of the brain (electrical resistance).

The following are specific examples of the method.

 Example 1

Testing of city X was carried out.

During testing, questions were raised, including:

H1 (Rv) - Does anyone know that you have ever eaten fish before?

Z1 (Sv 1) - ... Have you ever abused alcohol before?

Z2 (Sv 2) - ... Have you ever used drugs before?

Z3 (Sv 3) - ... Do you have a gambling addiction?

Question posed for resolution: “Does Mr. X. come up with a conscious answer to the read questions Z1, Z2, Z3 of the psychophysiological reactions characteristic of the reactions accompanying the actualization of the image (or stress, or a set of reactions that include updating the image and stress)? "

In FIG. 1 to question H1 and Z2 in the 5 second interval after reading the question, there is a significant reaction on the RAG channel, on question H3 there is no such significant reaction. On reading the Breathing channels (VDH and NDH), after reading questions H1 and З2, a pronounced reaction is also observed, and on question З3 - a very strong reaction with increasing depth of inspirations-expirations from reduced to increased relative to the background indicators, including breath holding, indicating a short-term neurological upset. It can be reliably observed by observing similar reactions in the analysis of the polygram that significant reactions were obtained to these questions. Conclusions of diagnostic techniques are usually formulated about a “significant reaction to the question” and end.

Further, to the question H1 (which does not have any motivational and emotional significance, that is, threatening nothing to Mr. X.) about whether anyone knows that she previously used fish, she answers: “Yes.” When examining questions in the pre-test conversation, the specialist actualizes recalls of moments in her past life when she ate fish and, as a rule, she recalls images of declarative or procedural memory. For example, this is, respectively, either the image of a fish, or the process when she ate fish, accompanied by an emotional attitude to this process of eating fish. Therefore, with a high degree of probability, we can assume that when asking question H1, she actualizes a certain image in her memory, which can be accompanied by an emotional (i.e. stressful) reaction, which we see on the diagram - significant reactions on the RAG channel and the Breathing channels.

Further, to question Z1 (this question of alcohol abuse is of motivational significance for City X., since the identification of facts of alcohol abuse may be the reason that she will not be hired), we also observe elevated ones (relative to the arithmetic mean for all questions test), but minor (regarding the response to question H1) reactions on the RAG channel and the Breathing channels. Since in response to this question no RAG responses were received equal to or greater than that to question H1 (to which group X. most likely to have emotionally significant images), we can doubt that upon presentation of an emotionally insignificant question Z1 of group X. actualized images in long-term memory - probably did not update images in long-term memory, or updated an insignificant image.

Further, to question Z2 (this question about the use of drugs ever has motivational significance for City X., since the identification of facts of drug use may be the reason that she will not be hired), we also observe significant reactions on the RAG channel and the channels of the Breath. And since similar answers were received in response to this question, as well as to question H1 (to which group X. most likely emotionally significant images were updated), it can be assumed by analogy that when question Z2 is presented, group X. received reactions characteristic of actualization of an emotionally significant image.

Further, to question 3 (this question is about whether city X is addicted to gambling), we observe a very strong reaction on the Breathing channels, but we do not observe a pronounced reaction on the RAG channel. The reason for this paradox has not yet been proved, but this fact itself is already proof that the channels of the Respiration and the channel of the RAG fix various physiological functions of the body of group X.

It remains unproven - on which of the above channels of the polygraph are the functions of actualization of images in memory (that is, memories of something) better observed, and on which - the functions of emotional tension (stress)?

For evidence-based differentiation of the aforementioned polygraph channels according to this principle, when conducting the study, it was required to use one more mandatory (in our opinion) device for the polygraph - the “Memory” module, which registers signals coming from temporal and airborne sensors. How is the differentiation of these channels using this module? The metric indicators of the module, which make it possible to differentiate correlations, can be observed on table No. 1.

The following changes in the metric indicators of the module were observed (shown in table 1):

- after reading the representative question H1, the electrical activity indicators recorded by both temporal (limbic cortex activity zone) and airborne (temporal cortex activity zone) sensors increase relative to the background, which accordingly correlates with Breathing and RAG channels;

- after reading question Z1, the indicators of electrical activity recorded by temporal (zone of activity of the limbic cortex) sensors increase very slightly, and the indicators of electrical activity recorded by airborne (zone of activity of the temporal cortex) sensors increase quite significantly, which correlates with the channels of Respiration and RAG;

- after reading out question Z2, the indicators of electrical activity recorded by temporal and airborne sensors increase significantly, which correlates accordingly with the channels of Respiration and RAG;

- after reading question Z3, the indicators of electrical activity recorded by temporal sensors significantly increase and the indicators of electrical activity recorded by airborne sensors are very insignificant, which correlates with Respiratory and RAG channels accordingly.

Thus, we can conclude that the temporal sensors of the “Memory” module correlate with the dynamics of the Breathing channels and the indicators of airborne sensors correlate with the dynamics of the RAG channel.

In this particular example, since the indicators of the temporal sensors of the brain indicate an increase in the activity of the limbic cortex, that is, the enhancement of emotional processes, and the indicators of the scent sensors indicate the intensification of the processes in the temporal cortex, which is involved in the processes of updating images in long-term memory, we can accordingly draw conclusions that:

- to the question H1 and Z2 of group X. gives the responses typical for actualization in the memory of emotionally significant images,

- to question Z1 of group X. gives the response responses characteristic of actualization in the memory of an emotionally insignificant image,

- to question Z3 of group X. gives responses that are characteristic of severe emotional stress, in which the images in the long-term memory are not updated.

Example 2

The second test was carried out for Mr. X.

The same questions were presented as in Example 1.

In FIG. 2 to question H1 and Z2 in the 5 second interval after reading the question, there is a significant reaction on the RAG channel, on question H3 there is no such significant reaction. After reading the channels of the Respiration after reading out the questions H1 and Z1, a pronounced reaction is also observed, and on questions Z2 and Z3, there is no significant reaction. It can be reliably stated that a significant reaction was received to question H1, a dubious reaction to questions Z1 and Z2, and no significant reaction to question Z3.

Further, to the question H1 (which does not have any motivational and emotional significance, that is, threatening nothing to Mr. X.) about whether anyone knows that she previously used fish, she answers: “Yes.” At the same time, with a high degree of probability, we can assume that when asking question H1, she actualizes a certain image in her memory, which can be accompanied by an emotional (i.e. stressful) reaction, which we see on the diagram - significant reactions on the RAG channel and the Breathing channels.

Further, to question Z1 (this question of alcohol abuse is of motivational significance for City X., since the identification of facts of alcohol abuse may be the reason that she will not be hired), we also observe elevated ones (relative to the arithmetic mean for all questions test), but minor (regarding the response to question H1) reactions on the RAG channel. On the channels of the Respiration there is a significant reaction. Since no RAG reactions were received in response to this question that are equal to or greater than that of question H1 (to which group X. most likely updated emotionally significant images), it can be doubted that upon presentation of an emotionally significant question Z1 groups X. updated the images in long-term memory - probably did not update the images in long-term memory.

Further, to question Z2 (this question about the use of drugs ever has motivational significance for Mr. X., since the identification of facts of drug use may be the reason that she will not be hired), we also observe insignificant reactions on the Breathing channels and significant on the RAG channel.

Further, to question 3 (this question is about whether city X is addicted to gambling), we do not observe a reaction on the Breathing and RAG channels.

The metric indicators of the module, which make it possible to differentiate the correlations, are given in table 2.

You can observe the following changes in the metric indicators of the module:

- after reading question H1, the electrical activity indicators are recorded, which are recorded by both temporal (zone of activity of the limbic cortex) and airborne (zone of activity of the temporal cortex) sensors, which correlates accordingly with the channels of the Respiration and RAG;

- after reading question Z1, the indicators of electrical activity recorded by temporal sensors slightly increase and the indicators of electrical activity recorded by airborne sensors increase very slightly, which correlates with the channels of Respiration and RAG;

- after reading question Z2, the indicators of electrical activity recorded by temporal sensors do not increase, and recorded by airborne sensors significantly increase, which correlates accordingly with the Breathing and RAG channels;

- after reading out question Z3, the indicators of electrical activity recorded by temporal and airborne sensors do not increase, which accordingly correlates with the Breathing and RAG channels.

In this example, we can conclude that:

- to the question H1 of group X. gives the responses typical for actualization in the memory of emotionally significant images,

- to question Z1 of group X. gives responses that are characteristic of the emotional significance of the question, but without actualization in the memory of images;

- to question Z2 of group X. gives the responses typical for actualization in the memory of an emotionally insignificant image;

- to question Z3 of group X. does not give response responses characteristic of stress and actualization in the memory of any image.

Table 3 shows the test results for examples 1 and 2.

Thus, the use of the proposed method allows for polling using a polygraph to obtain more reliable and accurate results, while compared with previously used methods, it becomes possible to obtain additional information, namely to determine the functional nature (updating the image, stress, etc.) of the responding psychophysiological reactions.

Example 3

Testing of G. X. was carried out using the MZRV test.

The questions presented are shown in FIG. 3. In addition to the usual neutral, significant and control questions, representative questions H3 and H6 and obviously false questions H1 and H5 were presented.

Question posed for resolution: “Does Mr. X. come up with a conscious answer to the read questions Z1 and Z3 of the psychophysiological reactions characteristic of the reactions accompanying the actualization of the image (or stress, or a set of reactions that include updating the image and stress)?”

In FIG. 4 shows a view of polygraphs of the MZRV test. On polygrams, a doubtful case is observed when the amplitude of the curve of the skin-galvanic reaction (RAG) (measured in the 8 second zone after asking the question) on test question Z1 and Z3 is higher than the background indicator and has approximately the same value with the amplitude of the RGR on representative question H2 ( according to which it is established that the tested person must update the images). On the polygrams of test question Z1, changes in Respiration and blood pressure are observed, indicating a high emotional stress. On the polygrams of question 3 there are no such reactions indicating a high emotional stress, and therefore, a significant amplitude of RAG on this issue can be explained by increased electrical activity in the temporal lobe of the cerebral cortex, that is, updating the image in Long-term memory. Thus, without the application of the proposed method, it is not possible to reliably differentiate the cause of the reaction (strong emotional stress, or updating the image) according to one increased indicator of the RAG amplitude.

Question Z1

Table 4 shows the metric indicators of the "Memory" module.

The table shows that the indicators that record the electrical activity of the temporal lobes in response to question Z1 are significantly less than the representative question H2 and are comparable to question K1. This indicates that the electrical activity in the temporal lobe of the cerebral cortex after asked question Z1 is low, that is, characteristic of situations when the test person does not update the images.

At the same time, the indicators that record the electrical activity of the limbic cortex, in response to question Z1, are much higher than on representative question H2 and control question K1. This indicates that the electrical activity (and electrical conductivity) in the limbic cortex of the brain after asked question Z1 is high, characteristic of situations when the test person experiences emotional stress.

Question 3

Table 4 shows the metric indicators of the "Memory" module.

The table shows that the indicators that record the electrical activity of the temporal lobes, in response to question H3, are comparable to representative question H6 and slightly higher than to question K3. This indicates that the electrical activity in the temporal lobe of the cerebral cortex after asked question 3 is high, which is typical for the situation when the test person updates the images.

At the same time, the indicators recording the electrical activity of the limbic cortex, in response to question H3, are slightly higher than on representative question H6, the question of the knowingly false H5 and control question K1. This indicates that the electrical activity (and electrical conductivity) in the limbic cortex of the brain after asked question Z1 is high, not typical for situations when the test person is experiencing emotional stress.
