Description

The invention relates to medicine, namely to psychology and psychophysiology, and can be used to obtain objective data on the intellectual level, personality characteristics and cognitive activity of the subject during occupational selection, the identification and formation of his personal psychological portrait during testing for diagnostic purposes. The device relates to medical equipment, in particular to devices for biomedical use, and is intended to automate experimental studies using projective methods of psychological analysis, test questionnaires and selection methods with synchronous registration of physiological signals when a person identifies specific causes of suffering and physiological disorders from a large number of suspected pathogenic factors, as well as possibly information hidden by him during the investigation offenses either in the process of selection and verification of hired or working personnel.

Methods of psychological analysis and psychodiagnostics over the past decades have received significant development, which is due to the needs of medicine, psychology, work, sports. The most common methods are aimed at studying personal characteristics, motives of activity and relationships, characteristics of social behavior, individual professional abilities, characteristics of attention, memory, etc.

At the same time, approaches to the study of individual characteristics of a person are developed to a much lesser extent, allowing to open the core of the personality and identify the factors that influenced its formation and determined its current status. In this regard, methods of psychoanalysis are used in clinical practice, which allow for a subtle diagnosis of borderline conditions (Freud, Z. “Psychology of the unconscious”, M., 1990, pp. 39-310). However, these methods of researching the subconscious are laborious, and the results of their application depend on the skill of a specialist and a number of other factors, are subjective in nature, therefore their widespread use is difficult.

The well-known research method "lie detector", designed to determine the information that is deliberately hidden (Barland GN, Raskin DC "Anavaliation of field techniques in detection of deception". - Psychophysiology, 1975, 12, 3, p.321-330), is also not a full-fledged tool for psychosemantic analysis, since it determines only a small part of the psychosemantic elements, and accordingly with its help it is impossible to determine unconscious intrapsychic conflicts.

Thus, all these methods do not allow the study of the deep and true content of mental activity, which is largely determined by the content of the unconscious spheres of the psyche of the person being examined. This is due to the fact that the tested information, being accessible to consciousness, is under its influence, i.e. as if edited by consciousness, and the subject’s reactions to the test premises voluntarily or involuntarily change and contain an essential subjective component.

From the description of the patent of the Russian Federation No. 221886, IPC7 A61B 5/16, publ. 2003, a method of psychosounding is known, which consists in the following. Present semantic stimuli in a masked unconscious and in a conscious form. Behavioral and / or physiological reactions are recorded with the response time to an unconscious stimulus determined. Group the measurement results in accordance with the belonging to one semantic group. At the same time, two or more semantic groups are presented in an unconscious masked form, at least one of which is tested, and a control group that does not carry a semantic load and consists of a series of numbers. They support the level of operator readiness by presenting incentives with different time intervals with a given response rule. Incentives of at least one semantic group are presented both in a conscious and in an unconscious form, containing words that are different in meaning, the test rule for which the subject determines experimentally in the process of research on the acoustic and visual error signal. A test semantic group is statistically compared with a control group and subjective significance is determined upon reaching the reliability criterion. This method reduces the possibility of obtaining random results. However, this method is based solely on the approach of Fisher’s 25th frame, the reliability of which is ambiguous, and the possibilities for independent scripting during its implementation are significantly limited and focused exclusively on one methodological approach. Therefore, the use of this method does not allow to compare the individual personality characteristics of the subjects, to compare the subjects with each other, to form group meaning-physiological profiles for the selected group of subjects, to compare individual and group meaning-physiological profiles.

Patent of the Russian Federation No. 2192167, IPC7 AB 5/16, publ. In 2002, a method for assessing the functional state and personality characteristics of a person is protected, including presenting the subject with optical stimuli, analyzing the subject’s response to optical stimuli, drawing conclusions about the functional state and personality characteristics of the subject based on the analysis results, while optical stimuli are located outside the center of the visual space or outside the central region of the retina. Analyzed are emotional, vegetative, incl. electrodermal, customer reactions to optical stimuli, individual structures of spaces causing the most pronounced ergotropic and trophotropic reactions are compared with a list of certain standard structures of visual spaces. This method also does not allow to compare the individual personality characteristics of the subjects, to compare the subjects with each other, to form group meaning-physiological profiles for the selected group of subjects, to compare individual and group meaning-physiological profiles.

From the description of the patent No. 2209032, IPC7 A61B 5/01, A61B 5/16, publ. 2003, a known method for diagnosing the intellectual potency of the individual, adopted as a prototype. This method involves presenting a subject with a series of tasks or tests, measuring and recording changes in an uncontrolled consciously in the process of solving a physiological parameter. Moreover, for each test, the parameter changes are displayed in the form of a graph of the dependence of the thermal radiation from the skin of the temple on the time of the test. According to the form of the graph, the correspondence of changes in thermal radiation with the result of the task is established. The disadvantage of this method is the lack of psychological analysis in order to identify a person with specific causes of suffering and physiological disorders from a large number of alleged pathogenic factors, as well as possibly hidden information during the investigation of offenses, or in the process of professional selection and verification of a hired or working staff .

All the methods described earlier do not allow to draw up an objective psychological portrait (profile of semantic and physiological significance) based on the results of a simultaneous study.

The technical result from the use of the proposed method is the provision of the possibility of compiling an objective (minimizing the influence of the conscious subjective component) psychological portrait of the subject — a profile of meaning and physiological significance, which provides a comparison in quantitative indicators of the dynamics of changes in the profiles of meaning and physiological significance of any subject, comparison of subjects with each other, the formation of group psychological portraits of the selected group of subjects, a comparison of individual and group psychological portraits.

The indicated technical result is achieved by the fact that in the method of psychological analysis, including presenting a subject with a number of tasks and tests and measuring and recording physiological parameters, the subjects on the personal computer screen are presented incentives for projective techniques, questions and statements combined by a diagnostic scenario, and the subject for each stimulus by movement of a hand with a touch device for inputting information into a personal computer, it draws up the execution of the task and presents an answer s, while in the process of drawing and presenting answers to the subjects, they automatically carry out synchronous acquisition and processing of one or more electrophysiological signals that are variable to the psychoemotional response of the subject to stimuli, and at least one signal characterizing the movement of the hand with a touch-sensitive device for inputting information into a personal computer, and The results obtained are presented in tables and graphs in the form of a profile of meaning-physiological significance in relation to the tested sense clusters. The results of psychological analysis can be presented in the form of a “route” of a profile of semantic and physiological significance in relation to the test semantic clusters in a three-dimensional coordinate system - “mental”, “somatic” and “socio-ethical” objective psychological testing. The time for presenting individual stimuli included in the diagnostic scenario may not exceed the frame scan time of a personal computer video monitor. As physiological signals that are variable to the subject's psycho-emotional reaction to stimuli, signals of brain bioelectric activity from an occipital standard lead, or signals of brain bioelectric activity from several standard leads, or a skin-galvanic reaction signal, or signals of a skin-galvanic reaction and photoplethysmography, can be used, or signals of a skin-galvanic reaction, photoplethysmography and respiration, or signals of a skin-galvanic reaction, photoplethysmography and bioel electrical activity of the brain with occipital standard leads, or signals of a skin-galvanic reaction, photoplethysmography and bioelectric activity of the brain with several standard leads.

The subject draws tasks and presents answers on the field of the touch electronic tablet using a special pen - a pen-pointer, while the parameters of the movement of the pen-pointer and the pressure on pen, pauses before completing and moving on to the next task.

The subject draws out the execution of tasks and presents answers on the personal computer screen by manipulating the organ of the touch interface for entering information into a personal computer, and the degree of pressure on the organ of the sensory is used as signals characterizing the movement of the hand when performing manipulations with the organ of the touch interface of entering information into a personal computer information input interface, the parameters of the movement of this body and the pause before performing and moving to the next task.

The claimed method of psychological analysis meets the criteria of the invention of “novelty”, “inventive step” and “industrial applicability”, since there is no source of information from which the totality of distinguishing features and their causal relationship with the achieved technical result would be known, and the invention relates to medicine and is implemented using known means.

A causal relationship of the features that make up the essence of the invention with the achieved result (the possibility of quantitatively comparing the dynamics of changes in the profiles of meaning and physiological significance for any subject, comparing the subjects with each other, forming group psychological portraits for the selected group of subjects, comparing individual and group psychological portraits ) is expressed in the following. Due to the synchronous registration of physiological signals and signals characterizing the movement of a hand with a touch-sensitive device for inputting information into a personal computer upon presenting to the subject on the personal computer screen sequentially stimuli of projective techniques, and / or questions and statements combined by the diagnostic scenario, and performing tasks for the subjects, it becomes possible objectify the reactions of the subject and identify the stages of the study that have the greatest emotional significance for the subject, pre to present the results of quantitative analysis in the form of a profile of meaning-physiological significance in relation to the analyzed sense clusters. This allows you to compare in quantitative terms the dynamics of changes in the profiles of meaning and physiological significance for any subject, to compare the subjects with each other, the formation of group psychological portraits (profiles of meaning and physiological significance) for the selected group of subjects, comparison of individual and group psychological portraits.

Thus, in view of the foregoing, the features constituting the essence of the invention are in a causal relationship with the achieved result.

The claimed devices for psychological analysis are intended to automate experimental personality studies using projective techniques with synchronous registration of physiological signals and work as follows. Pre-form the semantic database (SBD). Moreover, each semantic sphere is tested by a combination of stimulus synonyms and related words that are semantically related. In SBD, stimuli are distributed into groups, for example, as follows: 1 - a group of control non-test stimuli that do not carry a semantic load and consist of a series of numbers; 2 - a group of test stimuli containing meaningful words, phrases, visual or sound images, the significance of which should be investigated; 3 - a group of non-test incentives containing meaningful words, phrases, visual or sound images, with the help of which they form the necessary level of operator readiness and a conditional defensive reaction; 4 - a group of stimuli, in which words, phrases, visual or sound images of the previous group can be used, which were accompanied by sound reinforcement and a message about the mistake made, allowing to form an alarming expectation reaction.

First, consider the operation of the first embodiment of the claimed device.

Before turning on the device, the corresponding sensors and electrodes of unit 1 are placed in different parts of the body of the subject to record physiological parameters, while the skin-galvanic reaction sensor in the form of two electrodes is mounted on the index and ring fingers of one of the hands, chest and diaphragmatic respiration sensors are mounted on the chest and in the area of the diaphragm, a plethysmographic sensor is fixed on the middle finger of the hand, EEG electrodes - in accordance with standard leads. After connecting the sensors and electrodes and turning on the power, at first, the operability and proper functioning of all units of the device for psychophysiological analysis are checked. By supplying test signals, the operability of the sensors and the sub-electrode resistance of the electrodes of unit 1, sensitivity, frequency band and gain of each channel of the multi-channel amplifier 2, the operability of PC 4 and the electronic tablet 6 are checked. From PC 4, commands to set the gain and frequency bands of each are written to microcontroller 5 multichannel amplifier channel 2. In accordance with the survey scenario, the measured bioelectric signals in real time are analyzed and recorded in To 4. In the process of testing the video monitor 10 of the test (patient's) PC 4 the subject at regular intervals to meet a series of test questions and assignments. These questions and tasks relate to inclinations, abilities, personal qualities, have a neutral, verification and control character and are united by a diagnostic scenario. The subject realizes the answers to questions and tasks on an electronic graphics tablet 6 using a special pen (pen) 7. In the process of drawing and writing answers on paper over the screen of a touch-sensitive electronic tablet 6, synchronous removal and integral processing of EEG signals and printing signals are automatically performed - heart rate, galvanic-skin reaction, photoplethysmography, etc., and graphic data - parameters of movement and degree of pressure on the pen, pauses before performing and moving on to the next danie.

The results are presented in tables and graphs in the form of a profile of semantic and physiological significance in relation to the tested sense clusters and / or in the form of a “trace” of the profile of semantic and physiological significance in relation to the tested sense clusters in a three-dimensional coordinate system - “mental”, “somatic "And the" socio-ethical "objective psychological testing. To facilitate the work of the operator, it is advisable that the operator has his own monitor 9. In this case, the patient’s monitor 10 displays test tasks, and on the operator’s monitor - additionally the results of psychological analysis. To draw conclusions about the degree of problematicity of a particular topic, certain statistical criteria are used for the degree and reliability of the deviation of pictographic, printing and EEG indicators from average values in the context of the subject's activities (averaging and comparison of quantitative indicators for all tasks distributed across semantic clusters). In addition, for the expert assessment, the calculated parameters of the degree of consistency of the change in indicators across different channels in relation to semantic clusters are also used.

The work of the second variant of the claimed device differs from the work of the first in that a psychological analysis of two subjects is carried out at the same time, while the test scenario for each subject is set from PK12, the results of the examination from PK4-1 and PK4-2 are transmitted to PK12, in which an individual or group psychological portrait (profile of semantic and physiological significance).

This research method is a synthesis of a self-documented version of projective techniques using a special graphic tablet connected to a computer, and a method of instrumental lie detection (printing) using various physiological signals (EEG, ECG, RAG, PPG, respiration, EMG). The method is based on a joint analysis of trends in physiological indicators and parameters of behavioral activity when performing specific tasks of diagnostic scenarios with a special pen (pen-pointer) on an ordinary sheet of paper (a familiar technology for any subject), which is placed on a touch-sensitive electronic graphics tablet.

As parameters of behavioral activity, quantitative indicators are used, calculated on the basis of trends in the movement of the pen-pointer on paper on a touch electronic tablet and the degree of pressure on the pen (more than 256 gradations of the degree of pressure on the pen are recognized), as well as latent periods of delay before completing a task and before transitioning to the next assignment.

The results obtained using the claimed device (both in the first and second versions) help the operator (doctor) to determine the internal problems of the test subject (patient), which can significantly reduce the quality of his life and lead to diseases.

c) Saving of graphic images in a structured storage in relation to the stages of the used research scenario.

d) Assigning a mask of physiological signals by which quantitative indicators will be calculated and specifying a sign of inversion of the received sorted arrays for each type of physiological signals used.
