Description

TECHNICAL FIELD

The invention relates to the field of computing and meeting the vital needs of a person, in particular, to assessing a person’s rhythm, and can be used to improve the reliability and objectivity of diagnostics, as well as to the speed of compensation for disorders or the development of motor skills.

BACKGROUND

Rhythm, in the broad sense of the term, is a complex structure of time measurement. Estimation of the time intervals between the events is an extremely important adaptation mechanism, which allows organizing and structuring one's own activity to a person (respondent, research participant, patient, user of the percussion module described below). The assimilation of a given rhythm can be the simplest example of “timing” (Eng., Timing) of the ability to predict a subsequent event, which is closely related to executive functions — working memory, inhibition, and planning. Thus, it becomes obvious that rhythmic processes are involved not only in musical perception, reading, but also in cognitive activity.

The perception and reproduction (in this case, repetition) of rhythm, a special case of which are rhythmic patterns (patterns) is a complex coordinated process of simultaneous work of the auditory, motor, and prefrontal areas of the cerebral cortex. Auditory-motor synchronization implies both thoroughness of the auditory processing, for more accurate estimation of time intervals, and strict motor control over the movement being performed, as well as fine coordination between them. The mentioned rhythmic patterns (patterns), in a particular case, are a set or sets of sound stimuli with the same or different parameters of sound stimuli, and such parameters of sound stimuli are duration, volume, tone, type, etc. sound stimulus, as well as the interval between sound stimuli. It should be noted that, in the particular case, at least one of the above patterns is an integral part of the rhythm, in particular, the master rhythm and (or) the “distracting” rhythm (the “knocking” rhythm, the “interfering” rhythm, the interfering rhythm). A rhythm can consist of one pattern, which, in a particular case, can be repeated, or a rhythm can consist of at least two different patterns, each of which can be repeated in a rhythm or can be contained (only) once. It is worth noting that the distracting rhythm (a sequence of distracting sound stimuli), in the particular case consisting of distracting sound stimuli, or at least one distracting sound stimulus is reproduced by the respondent during reproduction (repetition) by the respondent of the setting rhythm (or when the respondent repeats the setting rhythm from memory) in order to prevent the respondent from reproducing (repeating) the master rhythm, to distract the respondent from the master rhythm, and the respondent must not stray from reproduction (repetition) master rhythm, as described in more detail in the framework of the present invention.

In the particular case, the cerebellum is the leading structure in motor coordination. However, besides his participation in basic motor functions, the cerebellum was supposed to be involved in the time measurement system.

As an elementary model for studying the timing function, such a concept as “rhythmic praxis” can be used - rhythmic auditory-motor synchronization (or synchronization of another modality), which is the ability to reproduce rhythmic sequences presented by hearing, as described in the framework of the present invention.

A promising possibility of correcting the function of rhythmic praxis is training in feeling the rhythm. Such trainings, in a particular case, improve hearing and motor coordination and manual motor skills, spatial and power parameters, and reading skills in respondents. Also, rhythmic praxis training is effective for groups of respondents suffering from motor disorders due to certain types of neuropathology, for example, people who have suffered a stroke.

It should be noted that timing (and its elementary model - rhythmic praxis) is interconnected with other executive functions. The cerebellum is activated when the respondent performs tasks for working memory and executive functions. In the particular case, an improvement in the perception of time, through the training of rhythmic feelings, leads to an improvement in psycho-physiological and cognitive indicators and an improvement in the indicators of executive functions. Working memory also takes part in the perception of time, as some finite resource, which with increasing difficulty of the task or increasing the tasks being solved is exhausted, which leads to errors, including in the perception of time intervals. In the particular case, executive functions can influence the repetition of a given (master, driving) rhythm, and executive functions are involved in synchronizing movement (hitting the arm) with a given rhythm and controlling the implementation of this synchrony (that the beat falls into a given rhythm). It is also worth noting that not only the cerebellum, but also the overlying sections of the brain indirectly can affect the rhythm. Thus, indicators of rhythmic praxis are potentially highly informative in terms of the characteristics of a number of motor and cognitive characteristics and can serve as a diagnostic tool, including in the clinic of neuro-oncological diseases in respondents (in particular, in children) for whom impaired hearing-coordination are a highly common consequence of illness.

Thus, there is a high need to improve the cognitive abilities of a person, in particular within the framework of school failure problems, for example, for normotypical children and children with pathologies (acute lymphoblastic leukemia and the consequences of its treatment, tumors of the posterior cranial fossa, etc.)

To date, the number of existing motor and cognitive simulators, allowing to improve the cognitive abilities of a person in health and disease is limited. Currently, classical techniques are known that are applied in practice in the form of expert paradigms related to the subjective perception of a particular researcher (operator, specialist, doctor, etc.). Objectification of the application of methods, implemented on the basis of the method described in the present invention for assessing a person’s rhythm sense (implemented by the described system), with methods for assessing the motor stereotypes of the targeted executive motor functions is necessary. To create such simulators, it is necessary to evaluate the feeling of a person’s rhythm.

The prior art method and device for training cognitive skills (see US2014352521 (A1), publ. 12/04/2014), which includes providing the user through the user interface of the computing device (WU) musical training rhythm, including at least one which includes displaying to the user, via the user interface of the computing device, a recording of a rhythm comprising at least one fixed rhythm marker and at least one rhythm label moving through the record and rhythm and also includes receiving by entering the interface from the user an indication from the user of the fact that the user perceives a moving mark with the aim of alignment with the fixed label and includes a display of information about the user that the user makes a mistake or not.

One of the drawbacks of this solution is the inability to record the rhythms and stimuli presented (reproduced) to the person, in particular, to the respondent.

Another disadvantage of this solution is the lack of computation of the respondent’s rhythm sense by calculating the value of the “accuracy” parameter, which determines the deviation of the intervals of the recorded signals from the respondent of the master rhythm from the specified interval between the sound stimuli of the master rhythm, and the “sustainability” parameter, which determines how exactly the respondent keeps the reproduced he sets the rhythm.

Also from the prior art known method and system (see US2010217159 (A1), publ. 08/26/2010), in which is formed (generated) reference signal with equal intervals between events (stimuli) and the provision of such a signal to the user, as well as registering contact between the legs of the user with the surface and the formation of a response (trigger) signal in response to such a contact, and comparing the response signal with the reference signal in order to establish the fact of advance or lag response in response to drove compared with a reference signal, and the guide signal is carried presentation to the user, is used to achieve symmetry user when kicking motion to improve the user's gait.

One of the drawbacks of this solution is the inability to record the rhythms and stimuli presented (reproduced) to the person, in particular, to the respondent.

Another disadvantage of this solution is the lack of computation of the quantitative characteristic of the respondent's rhythm sense by calculating the value of the “accuracy” parameter, which determines the deviation of the intervals of the responding signals of the master rhythm from the specified interval between the sound stimuli of the master rhythm, and the “sustainability” parameter, which determines how smoothly the respondent Holds the rhythm that plays it.

Also from the prior art known method and device to improve the ability in the field of education (see US7122004 (B1), publ. 10/17/2006), in which the formation of the reference signal with equal time intervals between events, providing the user with a trigger , determining the time dependence between trigger manipulations and providing a reference signal, generating a guide signal, which is a function of the time dependence, and from time to time it is presented to the user and the image is displayed, which varies depending on the manipulations of the trigger by the user, thereby improving the accuracy of the synchronization of the user's response to the reference signal.

One of the drawbacks of this solution is the inability to record the rhythms and stimuli presented (reproduced) to the person, in particular, to the respondent.

Another disadvantage of this solution is the lack of computation of the quantitative characteristic of the respondent's rhythm sense by calculating the value of the “accuracy” parameter, which determines the deviation of the intervals of the responding signals of the master rhythm from the specified interval between the sound stimuli of the master rhythm, and the “sustainability” parameter, which determines how smoothly the respondent Holds the rhythm that plays it.

The proposed method allows you to overcome at least part of the above disadvantages or all of these disadvantages, as well as to realize the advantages of the present invention, as described in the framework of the present invention.

DETAILED DESCRIPTION

The objects and features of the present invention, methods for achieving these objects and features will become apparent by referring to exemplary embodiments. However, the present invention is not limited to the exemplary embodiments disclosed below, it may be embodied in various forms. The entity described in the description is nothing but specific details provided to assist a person skilled in the art in an exhaustive understanding of the invention, and the present invention is defined only in the scope of the appended claims.

Used in the present description of the invention, the terms "component", "element", "system", "module", "part", "block", in particular, "component", and the like, are used to denote computer entities (for example, objects associated with a computer, computational entities), which may be hardware, in particular, equipment (for example, a device, a tool, an apparatus, an apparatus, an integral part of a device, in particular, a processor, a microprocessor, a printed circuit board, etc.), software m (for example, executable program code, compiled application, program module, part of software and / or code, etc.) or firmware (firmware / firmware). For example, a component can be a process running on a processor, a processor, an object, an executable file, a program, a function, a method, a library, a subroutine, and / or a computing device (for example, a microcomputer or computer) or a combination of software or hardware. .

The described method (and the system for its implementation) can be used to assess the feeling of a person’s rhythm (respondent), as well as to diagnose and correct rhythmic praxis on the norm (in the absence of various pathologies in the respondent) and pathology. The described method (and system) makes it possible to evaluate at the moment, as well as to improve the ability of the respondent to repeat, retain and reproduce rhythmic sequences (series) of sounds of varying complexity during training.

In FIG. 1 shows one of the exemplary embodiments of a system that implements a method (or at least one part of the present method) described within the framework of the present invention. The system shown in FIG. 1, contains a percussion module (percussion device, percussion device, pad - from English pad) 110, which may include a “working” surface on which the user performs hand strokes), which allows the respondent to register (detect) hand strikes during the tapping (blows in particular, rhythmic serial hand beats (serial rhythmic acts) by the respondent on percussion module 110. It is worth noting that percussion module 110 may include (contain) an integrated display, for example, a liquid-crystal display (liquid crystal tallic display), which shows the moment of impact by the respondent on the percussion module 110. It is worth noting that in a particular case, at least one LED can be used to visualize the respondent’s strikes on the percussion module 110 or in addition to the integrated display. higher rhythmic praxis is a rhythmic auditory-motor synchronization (or synchronization of another modality), which is the ability of the respondent to reproduce rhythmically presented sequence. Rhythmic praxis, in a particular case, is a tapping test, i.e. the respondent performs rhythmic beats at a given rhythm (tempo) of the pacemaker (program metronome, program rhythm master, program module for generating rhythm and / or signals, in particular, stimulating signals). Said rhythm adjuster is implemented by a rhythm generation module 210 (FIG. 2) that generates at least one rhythm or sound stimulus (which is described in more detail in the framework of the present invention), in particular, a rhythm generating and distracting rhythm at least at least one distracting sound stimulus, etc., as described in more detail in the context of the present invention. Rhythmic serial sequences, in the particular case performed by the respondent's flexing the wrist joint, in the particular case, do not require high spatial accuracy and are fairly simple in coordination terms, since are not performed due to the inhibitory activity of the antagonist muscles, as is the case when moving to a spatial target, but by damping the speed due to a collision with a solid fixed surface of the percussion module 110. In the particular case, tapping is the simplest rhythmic motor act in a person (respondent ), and its indicators may indicate the degree of development of a number of motor skills. Also, the percussion module 110 allows the respondent to convert the percussion module 110 to analog or discrete (digital) signals (recognizable signals), which are then transmitted to the sound card 120, which, if necessary, converts the above-mentioned recognizable signals (received from the percussion module 110 ) into discrete (digital) signals. As mentioned above, the percussion module 110 can convert the respondent's beats on the percussion module 110 into discrete (digital) signals. Further, discrete (digital) signals can be transmitted to sound card 120 in digital or analog format (form), in particular, by means of at least one analog cable (for transmitting said signals in analog format) or by means of at least one digital cable (for transmitting the mentioned signals in digital format). In the case of the transmission to the input (in particular, to one of the channels) of the sound card 120 of the percussion module 110 of the above signals in analog format, then, as mentioned above, the sound card 120 converts the transmitted to the input (in particular, to one of the channels a) sound card 120 analog signals into discrete (digital) signals. Further, signals (recognizable signals) in a discrete (digital) format (form) are transmitted to a personal computer 130, on which recognizable signals in a discrete (digital) form are processed (interpreted) by software installed on personal computer 130, in particular, processed by a software conversion module recognizable signals in a universal format (form) 220 (FIG. 2), as described in more detail below. It is worth noting that the universal format (form) is one of the well-known digital audio formats (the format of presentation of audio data (audio data), which is used in digital audio recordings, as well as for storing the recorded material on the storage device of a personal computer 130 and other electronic storage media ( audio media)). The audio format mentioned may be an uncompressed audio format (for example, WAV, AIFF), a lossless audio format (for example, APE, FLAC), a lossy audio format (for example, MP3, Ogg), may be a modular music format, etc. .

It is also worth noting that the percussion module 110 can be installed (in particular, mounted) on the stand, which is a rigid structure on which the percussion module 110 is fixed and which (the design) allows you to adjust the location of the percussion module 110 in height and angle of inclination for the most convenient operation respondent with percussion module 110. It is worth noting that percussion module 110 is a module (block, in particular, device, hardware, hardware module) recognition (and, in the particular case, reg the signals generated by the respondent, while the signals may be motor signals (realized by the respondent in the form of mechanical effects on percussion module 110) or sound signals that are the respondent's response signals to the specified rhythm (in particular, the respondent repeats the specified rhythm or stimuli). In the particular case of the percussion module 110 is a converter of mechanical effects in the signals described in the framework of the present invention, in particular, in electrical signals or audio signals. So, in the particular case, the percussion module can be implemented by a mechano-electric converter, an electro-kinetic converter, etc.

Also, the system shown in FIG. 1, contains a sound card (sound card) 120, in particular, a multichannel sound card, which may be an external (with respect to a personal computer 130) sound card, for example, a USB sound card (USB sound card), or a built-in (integrated) card. a personal computer with an audio card (in particular, implemented by at least one chip, a processor or a microprocessor), a sound card (audio card) installed in the personal computer 130, etc. Sound card 120 may include a stereo microphone input (may be equipped with a stereo microphone input).

It is worth noting that the sound card 120 allows you to transfer and record (and, in particular, save) recognized signals, in particular, a stereo signal (stereo, two audio signals, two audio signals, a signal via two audio channels) to a personal computer 130, in particular into a software module that converts recognizable signals into a universal format (form) 220 and (or) into a software analysis and presentation module 230, and / or into a data storage device of a personal computer 130, with the first audio signal (in particular The rhythm audio signal, for example, the master rhythm audio signal, is recorded in one recording channel, in particular, the audio recording (audio file), and the responder response audio signal (beats on the percussion module 110 performed by the respondent) is recorded in another recording channel, in particular, audio recording ( audio file). It is also worth noting that distracting stimuli (in particular, distracting rhythms), including aversive stimuli (and rhythms) described in the framework of the present invention, can be recorded in another recording channel. It is worth noting that in the particular case the distracting stimulus is recorded in the form of sound along with the rhythm, in particular, into the same channel into which the rhythm is recorded. It is also worth noting that when performing data conversion in a universal format into an intervalogram format, in particular, into a set (in the particular case, into an array) of data, which are points (tags) of the intervalogram, a software analysis and presentation module 230 (FIG. 2) together while preserving said transformed data, time stamps of the beginning and end of at least one distracting stimulus, distracting rhythm, etc. can be saved. It should be noted that the above-mentioned data storage device can be a hard disk drive, a solid-state drive, flash memory, etc. Thus, the sound card of the master rhythm is transmitted to the sound card 120 (in particular, to one channel of the sound card 120) from one of the outputs (audio outputs) of the sound card 120, in particular the audio signal converted by the master card 120 sound card 120 210 (FIG. 2) and transmitted in digital form to the sound card 120, for example, by means of a USB cable (in the case of using an external sound card), a PCI connector or an ISA connector (in the case of using an internal sound card, ovannoy (modular) sound) and various connectors and corresponding computer bus (e.g., USB-bus, PCI-bus, ISA-bus, etc.), etc. It should be noted that the transfer to the sound card 120 (in particular, to one channel of the sound card 120) at least one rhythm audio signal, in particular, the master rhythm audio signal and / or the distracting rhythm audio signal from one of the audio card outputs (audio outputs) 120, in particular, the audio signal converted by the master rhythm sound card 120, is performed to ensure the simultaneous recording of signals (audio (or audio signals)) rhythm (or rhythms) and (or) sound stimulus (or sound stimuli) and audio signal (or audio signal fishing) with a percussion module) for two audio channels in a single audio file (sound file). Said synchronous recording of said signals allows further analysis by the software analysis and presentation module 230 after the software conversion converts recognizable signals into a universal format (form) 220 of the respondent’s strikes on the percussion module 110 and the sound stimuli of the master rhythm (for example, a metronome beat), as described in more detail described in the framework of the present invention, based on a single time ruler (time ruler, time scale, time scale), which allows to increase the accuracy l described in the framework of the present invention and carried out by the software module analysis and presentation 230 analysis or at least one part of it, in particular, the comparison of the specified rhythm and recorded by the hand responder to the percussion module 110.

It is worth noting that the system shown in FIG. 1, contains a sound reproducing device 140 that plays back at least one rhythm to the respondent, in particular, the master rhythm and / or the distracting rhythm, or at least one distracting sound stimulus and which is connected to the output of the sound card 120 ( in particular, to the output of the sound card 120, from which the audio signal (or audio signals) is supplied, of at least one rhythm, in particular the master rhythm and (or), in particular, the distracting rhythm and (or) any other rhythm described in framework present of the invention, or at least one sound stimulus, in particular, a distracting sound stimulus or a sequence of distracting sound stimuli. The audio playback device 140 may be speakers (speakers, speakers, loudspeakers, etc.), headphones (stereo headphones ) etc.

The sound card 120 also transmits a signal in a discrete (digital) format or in an analog format (in particular, to the second channel (input channel) of the sound card 120) from the percussion module 110. The above-mentioned synchronously recorded signals (audio signals) are converted into two channels discrete (digital) signal by sound card 120 and converted into a universal format (form), in particular, into a universal format of audio signals (format of audio data, audio format, in particular, into digital audio format), a software module converts The recognition of signals in a universal format (form) 220 (FIG. 2) and further analyzed by the analysis and presentation software module 230 (FIG. 2) (described in more detail below) to assess the respondent’s sense of rhythm, including the degree (in particular case, the accuracy) of the coincidence of the two rhythms (specifying the rhythm and response of the respondent). Recorded (or recorded when the playback device plays the sound 140 to the respondent at least one rhythm, for example, a setting rhythm, or at least one sound stimulus, for example, a distracting sound stimulus, and when the respondent repeats the setting rhythm) synchronously converted into discrete (digital) format signals transmitted (or transmitted) from sound card 120 to personal computer 130 after being converted into a universal format (form) by a software module that converts recognized signals 220 (FIG. 2) and after converting the data in the universal format into an intervalogram format, in particular, into a set (in particular, into an array) of data, which are the points (labels) of the intervalogram, the software analysis module and views 230 can be exported to a file (computer file), for example in a table format (for example, in the form of Table 2 below), a text format, and any other known format for subsequent work (in particular, analysis or presentation (display), for example , espondentu or operator) with them. Also, it is worth noting that the converted data into a universal format (form) by a software module converts recognizable signals into a universal format (form) 220 (FIG. 2) and transferred to a software analysis and presentation module 230 (FIG. 2) after performing the conversion and analysis The software analysis and presentation module 230 (FIG. 2) can be exported to a file, for example, in a table format, a text format, etc., for further work with them, in particular, their conversion into an intervalogram format, as described within of the present invention, for the analysis described by the software analysis module and presentation 230 (FIG. 2), for presenting (displaying) or reproducing to the respondent. It is also worth noting that the signals recorded synchronously, converted by the sound card 120 and transmitted by the sound card 120 to the personal computer 130, can be visualized (displayed) by the software analysis and presentation module 230 (FIG. 2) (in the particular case, without conversion by the software conversion module recognizable signals in a universal format (form) 220 (FIG. 2), in particular, can be transferred immediately (directly) to a software analysis and presentation module 230 (FIG. 2)) for conversion and analysis, which Lee describes in detail the present invention such a module and / or display on a monitor (display screen etc.) 150, also forming part of the system shown in FIG. one.

Software (computer program, application) installed on personal computer 130 includes program modules, in particular, for generating a master rhythm, for conversion, analysis (processing, interpretation), visualization, storage, etc. signals (including converted signals, as described in more detail in the framework of the present invention), which are described in more detail in the framework of the present invention. Thus, the software installed on the personal computer 130 includes a rhythm generation software module 210 (FIG. 2) which generates (generates) at least one sequence of signals that can be converted (in particular, by means of a sound card). 120) sound signals of varying intensity and tonality, in particular, in a rhythm (in a particular case in a master rhythm or a distracting rhythm), and are intended for the respondent to listen through the sound reproduction device 140 (intended s for playback by the interviewee sound reproducing apparatus 140).

The rhythm generation software module 210 (FIG. 2) includes a user interface (in particular, a graphical user interface) that allows the respondent or the operator (researcher, specialist) to adjust (change) the rhythm parameters (rhythms), such as, for example, the type of sound stimuli (eg, synchronous, asynchronous), frequency, duration, loudness, patterns (in particular, the rule or rules of change) rhythm, and patterns are a special case of rhythm, in particular the master rhythm or distracting rhythm, etc. It is worth noting that in the particular case, the rhythm is formed by the rhythm generation software module 210 (FIG. 2) from sound stimuli, which are sound recordings, in one of the well-known digital audio formats (the format of presentation of sound data used in digital audio recordings, as well as for further storage of recorded material on the storage device of the personal computer 130 and other electronic storage media (audio media)). The audio format mentioned may be an uncompressed audio format (for example, WAV, AIFF), a lossless audio format (for example, APE, FLAC), a lossy audio format (for example, MP3, Ogg), may be a modular music format, etc. . The above-mentioned sound stimuli (sounds, audio stimuli) can be complex sounds (for example, biologically or socially significant, including bell sounds, hammer sounds, metronome sounds, etc.). Sound stimuli can be stored in sound stimuli, which can be implemented by audio files containing sound stimuli sound recordings (signals) in one of the known audio formats stored on the storage device of the personal computer 130 and / or on the Internet, and / or on any other known devices, tools, services (services) data storage. Also, a library of sound stimuli (containing sound stimulus sound recordings) can be stored in a database of audio files on a personal computer 130 and / or on the Internet, and / or on any other known devices, means, services (services) of data storage.

It is worth noting that the rhythm generation software module 210 (FIG. 2), in the particular case, generates at least one rhythm with high frequency sampling, in particular, to accurately determine (estimate) the value at which the retention loss occurs rhythm by the respondent, as well as to assess (determine, calculate) the rhythm of the person

It is worth noting that the mentioned rhythm generation software module 210 (FIG. 2) allows (the respondent or the operator) to adjust the parameters of the (generated) rhythm (or rhythms) and / or sound stimulus (or sound stimuli) types of sound stimuli, through a user interface is the rhythm, the sequence of reproduction (sound) of sound stimuli, the volume of the sound, the frequency of the sound stimuli and other parameters, in particular, the parameters of setting strong and weak beats, the parameter of a stereo or mono stimulus, can ala - left or right, etc. Setting (changing) rhythm parameters also allows you to generate a rhythm with a constant frequency, a rhythm with a strong and a weak beat (and, in the particular case, a strong beat signal differs in frequency from a weak beat signal), a duplicate rhythm, an increasing complexity rhythm rhythm or slowing rhythm, rhythm with varying frequency set by various functions, for example, exponential, linear, etc., trigonometric functions (sine, cosine, etc.), etc. Also, as a rhythm, in particular, a setting rhythm (stimulating sounds, stimulating signals), a set of audio signals verified by physiological properties can be used, and this set of audio signals verified by physiological properties is a standardized base of sounds that are standards for various sociological, biological and etc. types of sounds.

It is worth noting that the range of the task (by the respondent or operator through the said user interface of the rhythm generation software module 210 (FIG. 2)) of the rhythm frequency (in particular, the driving rhythm or the distracting rhythm) of the rhythm generation software 210 (FIG. 2) can be for example, from 4 to 240 (or more) beats per minute. So, in the particular case, such specified rhythm frequencies (in particular, the master rhythm) can be 10 (the interval between sound stimuli (in particular, between the peaks of sound stimuli) 6000 milliseconds (ms); frequency 0.17 Hertz (Hz)), 40 (interval between sound stimuli 1500 ms; frequency 0.67), 60 (interval between sound stimuli 1000 ms; frequency 1 Hz), 90 (interval between sound stimuli 667 ms; frequency 1.5 Hz), 120 (interval between sound stimuli 500 ms; frequency 2 Hz), 150 (interval between sound stimuli 400 ms; frequency 2.5 Hz), 180 (interval between sound st mules 333 ms; frequency 3 Hz) etc. rhythm sound stimuli (in particular, beats of the program metronome) per minute. For example, a sound stimulus by an operator or respondent can be set (tuned, selected) a pure tone with a frequency of 1000 Hz and a duration of 100 ms, and the operator or respondent can set the duration of the entire (at least one) rhythm in its entirety or the duration of at least , one sequence of sound stimuli. It is worth noting that, in the particular case, the rhythm includes (consists of) one or more sequences of sound stimuli. For example, a rhythm may consist of a sequence of sound stimuli with a frequency of 0.67 Hz and an interval between sound stimuli of 1500 ms, a sequence of sound stimuli with a frequency of 1 Hz and an interval between sound stimuli of 1000 ms, a sequence of sound stimuli with a frequency of 2 Hz and an interval between sound stimuli 500 ms. The respondent or the operator can also set the duration of the sound stimuli, for example, the duration of the sound symbol can be 5, 10, 30, 50, etc. milliseconds

For the rhythm, in particular, the setting rhythm, the respondent or the operator in the user interface of the rhythm generation module 210 (FIG. 2) can select at least one of the types (variants) of sound stimuli (set, set, sequence) that make up rhythm, in particular, the setting rhythm. For example, a type of sound stimulus (or types of sound stimuli) of a rhythm, in particular, a master rhythm, can be or can be chosen a sound (signal) frequency of 1000 Hertz (Hz), which is classical for psychophysiological studies, or a pure tone (signal) of any other frequency as well as any sound (audio recording of sound) from the library of sound stimuli.

So, for example, for rhythmic praxis, in a particular case, the frequency of the signal (in particular, sound) does not change, and the duration of presentation of the rhythm, in particular, the master rhythm, and the duration of the sound rhythm stimuli, in particular, the master rhythm, is chosen by the respondent or operator by using the user interface of the rhythm generation software module 210 (FIG. 2), which is part of the software installed on the personal computer 130.

It is worth noting that the respondent can play a distracting sound stimulus or distracting sound stimuli, or at least one distracting rhythm in the process of repetition (reproduction) by the respondent of the setting rhythm. Parameters of the distracting sound stimulus (or distracting sound stimuli) or at least one distracting rhythm can be set (customized) by the operator or respondent in the graphical user interface in the rhythm generation software module 210 before the rhythm and sound stimulation software generation module 210 begins .

In the particular case, in the process of repetition (reproduction) by the respondent of the setting rhythm, the operator or respondent can reproduce the respondent with a distracting sound stimulus (or distracting sound stimuli, in particular, at least one sequence of distracting sound stimuli) rhythm by the operator or respondent selecting a user interface element (in particular, a soft button) that transmits to the program module It is necessary to play the rhythm 210 of a command (program instruction) to play at least one corresponding distracting rhythm or sound stimulus.

The software installed on the personal computer 130 also includes a software module for converting recognized signals into a universal format (form) 220 (FIG. 2), which converts recognized signals (discrete (digital) signals from a sound card 120) into the above-described universal (standard ) format (audio format), which is the response (responses) of the respondent to the master rhythm, in a universal format (form). Also, a software module converting recognizable signals into a universal format (form) 220 (FIG. 2) stores the universal format (form) of the respondent's response sequence to a master rhythm, converted by the sound card 120 into a discrete (digital) signal or signals previously. It is worth noting that the respondent’s responses to the master rhythm are reproduced (in this case, by repetition) by the respondent of the master rhythm on the percussion module 110. The data (responses of the respondent to the master rhythm) in the universal format (form) is transmitted to the software analysis and presentation module 230 (FIG. 2), in which data is converted in the universal format to the intervalgram format, in particular, in the set (in the particular case, in the array) of data, which are points (labels) of the intervalogram, the sequence of responses of the respondent to the rhythm is determined by indicators (values, values) of stability and fidelity (in this case, repetition) the master rhythm, as described below, in particular, the above analysis includes an assessment of the human rhythm (respondent). In the particular case of a software module converting recognized signals into a universal format (form) 220 converts the input continuous audio signal into a numerical sequence with a sampling frequency of 44.1 kHz and a coding depth of 16 bits. The mentioned numerical sequence is stored in the computer’s memory (130, FIG. 1) and processed by the analysis and presentation software module (230, FIG. 2) using a shock search algorithm (responder response) to convert data in a universal format (converted recognizable signals into a universal format a software module for converting recognizable signals into a universal format (form) 220, FIG.2) into an intervalogram format, in particular, into a data set, which are points (labels) of an intervalogram. It is worth noting that, in the particular case, the data set is an array of data (in particular, a numeric array), an approximate version of which is given in Table 2 below.

It is worth noting that the transformations carried out by the software module converting recognized signals into a universal format (form) 220 (FIG. 2) can be performed by this software module in real time (on the fly) and can (immediately) be transmitted to the software analysis and presentation module 230 in order to convert data in a universal format into an intervalogram format, in particular, into a set (in a particular case, into an array) of data that are points (labels) of the intervalogram, as well as for the purpose of analyzing and (or) presenting Averaging (mapping) the converted data and / or data resulting from the above analysis in real time.

Also, the software installed on the personal computer 130 includes a software analysis and presentation module 230 (FIG. 2), which converts data received by the module in a universal format (previously converted recognizable signals into a universal format by a software module converting recognized signals into a universal format (form) 220, FIG. 2), in the format of an intervalogram, in particular, into a set (in a particular case, into an array) of data, which are points (labels) of the intervalogram, as well as there is an analysis of transformed recognizable signals, and this analysis, in the particular case includes the implementation of a quantitative assessment of the response of the respondent to a given rhythm (correspondence of reproduction (repetition) by the respondent to the specified rhythm) or to the specified rhythms and performs the presentation (display, visualization) of the results of said analysis in the form of a table or tables, or in the form of a graphical representation, for example, in the form of a graph or graphs, in particular, the intervalogram (tempo gram) or intervalogram (tempogramm).

The mentioned conversion of data received by the module in a universal format (previously converted recognizable signals into a universal format by a software module converting recognizable signals into a universal format (form) 220, FIG. 2), into an intervalgram format, in particular, into a set (in the particular case, into the array) of data that are points (labels) of the intervalogram includes the search for beats (response of the respondent) in the audio signal (in particular, in the audio stream, the audio signal), converted and, in a particular case, stored in a universal format (as described above), by a software module for converting recognized signals into a universal format (form) (220, FIG. 2). Next, the software analysis and presentation module (230, FIG. 2) converts the detected peaks of beats (in the particular case, the detected peaks of the beats are digitized) into the format of the intervalogram, in particular, into a data set (in the particular case into an array of data), which are points (labels ) intervalograms, and an example of the result of such a conversion is shown in Table 2. In the particular case, the mentioned data set (data array) contains amplitudes and time of impacts (in particular, signal peaks, the recognition of which is described below). The search for beats in an audio signal (in particular, in an audio stream, an audio signal) stored in a universal format (as described above) by the software analysis and presentation module (230, FIG. 2) is based on (uses) the determination of the time of a sharp increase in amplitude (in particular , loudness) of the audio signal converted into a universal format in comparison with the amplitude level preceding this moment, in particular, the level of the audio signal. The audio signal converted into a universal format (612, FIG. 6), in particular, the sequence (in computer memory (130, FIG. 3)) is oscillating, with variable frequency and polarity of the signal. A large number of local maxima and minima makes it inconvenient for a quick search for a sharp increase in the signal. For this reason, to determine amplitude changes (in particular, loudness) of an audio signal, a smoothed envelope (617, FIG. 6) is used, obtained from the root-mean-square averaging of amplitudes at predetermined intervals, in the particular case, equal to two hundred and twenty-second, which corresponds to a time of about five milliseconds (in the particular case, for signals converted to a universal format, for example, audio recordings in wav format, the sampling rate is 44100 Hz; 5 milliseconds corresponds to splitting into 200 intervals (intervals), so dividing 44100 by 200, it turns out 221):

,

,

Where:

- N is the number of counts, in the particular case, equal to two hundred and twenty-one counts (221 counts);

- k is the split interval of the audio signal into equal (fairly short) intervals.

является амплитудой (распознаваемого) аудиосигнала, преобразованного в универсальную форму (формат) с порядковым номером «j» в пределах интервала «k»;-

is the amplitude of the (recognizable) audio signal converted into a universal form (format) with the sequence number “j” within the interval “k”;

является результатом усреднения амплитуд «

» на интервале «k».-

is the result of averaging amplitudes "

"On the interval" k ".

That is, the amplitude of the curve in the k-th interval is equal to the ratio of the square root of the sum of all amplitudes of the audio signal at each count from one to “N” (in the particular case, N is equal to 221) to “N”.

Thus, the maxima (in particular, the peaks) of the envelope (711, FIG. 7) correspond to (are) the moments of the greatest amplitude, in particular, the volume of the (recognizable) signal, in particular, the audio signal.

To search for the mentioned maxima in the software analysis and presentation module (230, FIG. 2), an algorithm for detecting a peak signal in a time sequence in real time mode is used, where the time sequence is the above-mentioned envelope. It is worth noting that the floating adaptive threshold, calculated in this algorithm, allows to divide the mentioned sequence into intervals with a significant excess of the audio signal over noise. The current threshold value is estimated by several previous envelope values, which makes this algorithm applicable in real time when the subsequent behavior of the audio signal is not yet determined. The maximum envelope values at the received intervals form a set of candidates for the signal of the recorded beats. In addition to the signal of interest, the set may include background peaks (peak signals), which are extraneous noise at the beginning or end of the audio signal (in particular, audio recordings), random sounds of small amplitude (in particular, loudness), weak beats preceding the main or following him, etc., which are effectively excluded from consideration by the following selection conditions:

1) the peaks must be located within a time interval shorter than the duration of the audio signal (in particular, audio recordings). The boundaries of the interval are set by shifts relative to the beginning and end of the audio signal (in particular, audio recordings). In real time, the right border can change its position;

2) peaks must exceed a certain threshold value (preset) calculated relative to the maximum value from the set (levels specified in the software analysis and presentation module (230, FIG. 2), in particular, based on empirically obtained data). By default, the threshold is selected at the level of 10% of the maximum and can be changed in the settings, for example, of the (graphical) user interface of the analysis and presentation software module (230, FIG. 2). When operating in real time, the threshold level may increase as new beats are recorded, exceeding previous ones in amplitude (in particular, loudness). In this case, repeated selection of peaks in height, with the possible rejection of some of them;

3) in the case when the distance between two consecutive peaks is less than the specified one (for example, 50 ms, and this value depends on the specified frequency), one of them is interpreted by the above algorithm as background, and a peak signal with a larger amplitude is taken as the impact signal.

The described algorithm allows to determine (calculate) the moments of time when the volume (amplitude) of the audio stream reaches a maximum. The evaluation of the accuracy of determining the time can be carried out, for example, on measurements of the duration of intervals between beats of a metronome tuned to a fixed frequency, on measurements of the duration of intervals between responses (beats by a subject on a percussion module (110, FIG. 1)) in a universal format, etc. In the particular case that the time reference to the signal front, in particular, the audio signal, at the level of its half-height is preferable, since, in the special case, it gives a smaller scatter of the measured intervals compared to the maximum.

It is worth noting that a special case of the algorithm for detecting a peak signal in a time sequence in real time is an algorithm based on statistical dispersion (https://stackoverflow.com/questions/22583391/peak-signal-detection-in-realtime-timeseries-data, https://en.wikipedia.org/wiki/Statistical_dispersion).

In the particular case, the software analysis and presentation module 230 (FIG. 2) analyzes the parameters of discrete (digital) signals and the intervals between individual cycles of discrete (digital) signals transmitted by the software module converting recognized signals into a universal format (form) 220 (FIG. 2) and converted into the format of the intervalogram, in particular, into a set (in the particular case, into an array) of data, which are points (labels) of the intervalogram.

It is worth noting that the analysis and presentation (display, visualization) of the results of conversion and / or analysis (carried out by the software module of analysis and presentation (230, FIG. 2) and described in the framework of the present invention), for example, in the form of an intervalogram, a table, etc. d., can be carried out by the software module of analysis and presentation (230, FIG. 2), in particular, the results of the divergence of the master rhythm and the master rhythm that is reproduced by the respondent, in real time, in particular, (immediately) after the start of playback, the respondent from the master rhythm and / or (immediately) after the start of registering (detecting registration) module 110 percussive strikes on the percussion responder module 110.

In the process of analysis, a software analysis and presentation module 230 performs an analysis, in particular, an assessment (calculation, determination) of a person’s rhythm is carried out. Assessing a person’s rhythm feeling includes calculating by the program module an analysis and presentation 230 of the value (indicator) of the reproduction stability (in this case, repetition) by the respondent of the setting rhythm and the value (indicator) of the reproduction accuracy of the setting rhythm by the respondent.

It should be noted that the mentioned values (indicators) of stability and accuracy can be calculated for:

- rhythmic praxis mode, in particular, for assessing (calculating) the stability values and accuracy values for the rhythms reproduced by the respondent, in particular, rhythmic patterns (patterns), as well as for evaluating (calculating) the stability values and accuracy values for (holding) simple processes rhythm with obtaining objectified indicators of the above processes, and the time intervals and the function of (simple) timing are estimated. As mentioned above, rhythmic praxis is a mode in which the respondent repeats the master rhythm generated by the rhythm generation software module 210, trying to get into the generated rhythm as accurately as possible. As mentioned above, the rhythm generation software module 210 generates sound stimulus sequences (in particular, the master rhythm) with a given frequency, and the frequency is set (set, determined) by the operator or respondent through the user interface of the rhythm generation software module 210. Sound stimuli (stimulus) sounds, stimulus signals, stimulus sound signals) of the master rhythm can be selected by the operator or the respondent through the user interface ator program module 210 for generating rhythm sound stimuli from the library and, in the particular case are given harmonic signal frequency, duration, modulation and, in particular, sound can gradually increase or decrease in volume. As mentioned above, the sound stimulus can be a complex sound. In the particular case, one of the variants of rhythmic praxis is that the respondent keeps the rhythm in memory after the rhythm stops playing (or is temporarily suspended) by the operator or respondent at a certain point in time (during the reproduction of the rhythm respondent), and the respondent continues to play the rhythm (hold rhythm) from memory. It is worth noting that the point in time (for example, time (in particular, time delta)) from the beginning of the presentation of the master rhythm at which the playback of the master rhythm is stopped can be configured by the operator or respondent in the graphical interface of the rhythm 210 program generating module. that the pause time (absence) of the preset rhythm can be set by the operator or respondent in the graphical interface of the rhythm generation software module 210 pondentu (in particular, the time at which reproduction is not performed respondent pacemaker or pacemaker carried generation).

- the mode of interfering sound stimuli (interfering rhythms) for assessing (calculating) the value of stability and the value of accuracy for the ability to inhibit the respondent, and the respondent must retain the rhythm, including after reproducing the parallel rhythm of the distracting rhythm (sequence or set of distracting sound stimuli), or at least one distracting sound stimulus. In the particular case of the interfering sound stimuli mode, it is possible to evaluate (calculate) the retention indicators of the master rhythm, and the respondent’s ability to not switch to at least one distracting sound stimulus (in particular, the rhythmic sound stimulus distracting rhythm). In the mode of interfering sound stimuli (interfering rhythm), the respondent is simultaneously presented (reproduced) two sound sequences at once (in particular, a setting rhythm and a distracting rhythm), in particular, two sequences of sound stimuli, each of which has its own frequency, its own parameters (characteristics) sounding. It is worth noting that these two sound sequences differ in the frequency of each rhythm, and the frequency of the second (distracting rhythm) differs from the frequency of the master rhythm, so that the respondent can distinguish the master rhythm from the distracting rhythm, in particular, so that the respondent can distinguish the frequency of the master rhythm from the frequency of the distracting rhythm . For example, in the case of reproduction of sound stimuli to a respondent, which are metronome beats (program metronome or digital metronome), the number of beats per minute for a master rhythm can be 60 beats per minute, and for a distracting rhythm (interfering rhythm) the number of beats per minute can be 90 beats per minute. In the particular case, the respondent is reproduced (presented) first the first sequence of sound stimuli (rhythm, in particular, the master rhythm) and the respondent begins to repeat (reproduce) it with beats on the percussion module 110, and then the second respondent plays back (presented) the second sequence of sound stimuli (rhythm in particular, a distracting rhythm), to which the respondent should not be distracted, in particular, stray. In the particular case of the present invention, the distracting rhythm has the duration (duration) of reproduction to the respondent equal to the duration of the specifying rhythm, or may have a duration (duration) of reproduction to the respondent that is somewhat less (shorter) of the specifying rhythm, for example, the duration of reproducing the distracting rhythm less than the duration of the master rhythm by 1 second, several times, etc. It should be noted that the restructuring of the respondent to another frequency (from the master rhythm to the distracting rhythm), in particular, in the case of its change, is encryption (switching, knocking). It is worth noting that, in a particular case, at the required time, an operator or respondent in the user interface of the rhythm generation software module 210 by selecting (pressing) the soft button of one of the distracting (interfering) rhythms in real time starts such a distracting rhythm (or this option can be set programmatically, for example, after a certain time the interfering rhythm is turned on).

- mode of aversive sound stimulus (mode of aversive sound stimuli) for assessing (calculating) the value of stability and the accuracy of rhythm reproduction, in particular, the setting rhythm, and the stability of its retention during one-time presentation (reproduction) of an aversive stimulus to the respondent, simultaneously with the master rhythm. In the aversive sound stimulus mode, the respondent repeats the rhythm setting that is presented to him, trying to get the rhythm setting as accurately as possible. The rhythm generation software module 210 allows the generation of (simple) sequences of stimuli, for example, with a frequency of 4 beats / min. up to 240 beats / min, and the aversive stimuli (sounds) can be selected by the operator or the respondent from the library of sound stimuli and are disharmonious signals that distract the respondent from the stable reproduction of the master rhythm. The stimulus signal of a distracting sound stimulus (in the particular case of the aversive sound stimulus) can be a complex sound, including a biologically or socially significant one (for example, a bell sound, a hammer blow, etc.). It should be noted that the respondent’s ability to keep the rhythm setting, despite the arising (distracting, aversive) stimulus, is inhibition (suppression).

- aversive sound strike mode for assessing (calculating) the stability value and the accuracy value of the rhythm, in particular, the master rhythm, and the stability of its retention when a single discrete distracting sound stimulus is presented to the respondent. In the particular case, the beat is set as a custom tone, and the stimulus can be, for example, the sound of thunder, etc. In addition, the aforementioned beat can be presented randomly, periodically, only by pressing a software button (in the graphical user interface of the rhythm generation software module 210), which presents such an impact to the respondent. In the aversive sound strike mode, the respondent repeats the rhythm setting that is presented to him, trying to get as accurate as possible into the rhythm setting. It is worth noting that an aversive beat (sound stimulus) can be presented (played back) to the respondent one-time, with a given frequency, at random times in the process of playing the master rhythm or at a lagging time interval, and the parameters for presenting an averse blow (like any other stimulus and or rhythm), such as the time of presentation of the aversive strike to the respondent, the frequency of presentation of the aversive strike.

- the mode of rhythmic sound sequences (patterns, patterns) for assessing (calculating) the values of stability and the accuracy of the rhythm, in particular, the master rhythm, which is the pattern (template, structure), and the stability of its retention by the respondent. It is worth noting that the patterns are sound sequences of sounds, rhythms, and the presented rhythmic sound sequences obey the rules, for example, the rhythm of sound sequences (in particular, rhythmic sequences) can increase (accelerate) or decrease (slow down) when presented (reproduced) to the respondent. It should be noted that in the particular case of the conditions and parameters of the presentation of sound rhythmic sound sequences are determined by the patterns used in the practice of neuropsychologists and expertly evaluated by them. It is worth noting that the rhythmic sound sequences (patterns, patterns) described in the present invention can be stored in a library of rhythmic sound sequences (patterns, patterns), in particular, in a database of rhythmic sound sequences (patterns, patterns).

- the mode of memorizing the sound sequence for assessing (calculating) the value of stability and the value of the accuracy of the rhythm that the respondent reproduces, in particular, the master rhythm, from memory. In the mode of storing the sound sequence, the evaluation (calculation) of the respondent’s working memory indicators is also carried out when performing tasks (tasks) on sensorimotor synchronization. In the mode of storing a sound sequence, the respondent first plays the sound sequence (rhythm, in particular, the master rhythm) and after listening to it (after presenting (playing) the sound sequence to the respondent), the respondent repeats (plays) the heard sound sequence using a percussion module 110. Sound sequences (patterns, patterns) can be stored in a library of rhythmic sound followers. spines (patterns, patterns), in particular, in the database of rhythmic sound sequences (patterns, patterns), and with such sound sequences stored and presented to the respondent, they are compared by their reproduction indicators (in particular, the stability values are calculated (calculated) accuracy of the sound sequence by the respondent. It is worth noting that the sound sequences can be formed and presented to the respondents on the basis of neuropsy ologicheskih techniques selected expert and stored in the sound library sequences.

The value of the mentioned parameter “accuracy” (M) is the average value of the deviation of the intervals reproduced by the respondent (recorded by the respondent repeating signals of the setting rhythm) from the specified interval (between the sound stimuli of the setting rhythm) in milliseconds (ms):

Таким образом, значение упомянутого параметра «точность» («M») определяется (вычисляется) как отношение суммы разностей по модулю всех воспроизводимых респондентом (участником исследования (или даже обследования)) интервалов (в частности, интервалов регистрируемых сигналов повторения респондентом задающего ритма), ко всему числу (общему количеству) ударов (звуковых стимулов), сгенерированных метрономом, в частном случае, программным модулем генерирования ритма (210, ФИГ. 2) и предъявленных респонденту.Where

- the reproduced interval,

- specified interval (ie, 1500 ms for a rhythm of 40 beats / min, etc.), n is the number of beats (in particular, the rhythm stimuli presented to the respondent or the number of beats by the respondent in the percussion module). Thus, the value of the mentioned parameter “accuracy” (“M”) is determined (calculated) as the ratio of the sum of the differences modulo all replicated by the respondent (participant of the study (or even the survey)) intervals (in particular, the intervals of the recorded signals of the repetition of the responding rhythm by the respondent) to the total number (total number) of beats (sound stimuli) generated by the metronome, in the particular case of the rhythm generation software module (210, FIG. 2) and presented to the respondent.

In the particular case, the accuracy parameter indicates (determines, characterizes) how much the rhythm beat out (repeated) by the respondent falls into the master rhythm.

, т.е., в частном случае, аналогичен показателю дисперсии (в мс):The value of the “stability” parameter (“D”) is the value of the variation of the intervals reproduced by the respondent without taking into account the value

, i.e., in the particular case, it is similar to the dispersion index (in ms):

,

,

- среднее значение воспроизведенных интервалов.Where

- the average value of the reproduced intervals.

The stability parameter indicates how smoothly the respondent keeps (setting it playing) the rhythm that he repeats by striking (knocking out) the percussion module (110, FIG. 1).

Thus, the value of the “stability” parameter (“D”) is determined (calculated) as the square root of the ratio of the sum of the differences of all the intervals reproduced by the respondent (in particular, the intervals of the responding signal of the master rhythm recorded by the respondent) squared to the total number of beats ( in particular, the total number of sound stimuli) that sets the rhythm, in particular, the beats generated by the metronome, in the particular case of the rhythm generation software module (210, FIG. 2) and presented to the respondent.

To correctly compare the performance of tapping to different rhythms of the metronome, the values (parameter values) "M" and "D" can be normalized to the value of a given interval to obtain dimensionless values:

) будет высоким, что свидетельствует о точном, но неустойчивом воспроизведении ритма респондентом. И наоборот, высокий показатель нормированной точности (

) и низкий показатель нормированной устойчивости (

) будут свидетельствовать об устойчивом воспроизведении одинаковых временных интервалов, но не равных заданному (задающему) интервалу.In the particular case, if the respondent reproduces time intervals, on average, equal to 60 beats / min, but their range varies from 40 to 80 beats / min, then the rate of normalized accuracy (

) will be low, and the normalized stability indicator (

) will be high, which indicates an accurate but unstable reproduction of rhythm by the respondent. Conversely, a high rate of normalized accuracy (

) and a low rate of normalized stability (

) will indicate a steady reproduction of the same time intervals, but not equal to the specified (master) interval.

It should be noted that in case of a rhythm reproducible by the respondent from a rhythm reproduced by the respondent, the respondent may be offered a number of activities that can potentially improve his rhythmic indicators (sense of rhythm). For example, various cognitive simulators can be used to improve rhythmic indices (indices of sense of rhythm), in particular, improving the sensorimotor response, concentration and attention of the respondent. Also, to improve rhythmic indices (rhythm sense indices), various simulators can be used to train the working memory and attention of the respondent. After the course has been conducted by the respondent on at least one of these simulators, the respondent can improve the rhythmic indicators (rhythm sense indicators). If the respondent has dynamics, dynamics can be estimated objectively (by statistical methods) on the basis of the results obtained by this method.

It is worth noting that in the process of analysis, the software analysis and presentation module 230 calculates the indicators, which are listed in Table 1 of the interpretation of the calculated indicators.

Table 1.

Indicator Indicator Explanation of the indicator value Units Comments N The number of intervals (between sound stimuli) in the series, where the series is a common sequence of rhythms. As soon as the presentation stops (playback), the current measurement (measurement) ends, but a new measurement can be started and a new series will begin (sequence) PC The total number of sound stimuli minus one (i.e., the number of intervals per unit is less than the number of sound stimuli presented (reproduced) to the respondent)
The number of intervals is less by one due to the fact that the interval is a difference and there is no pair (in particular, the previous one) for the first strike (in particular, the stimulus). dt Duration of the series seconds The duration of the series before going beyond the established “corridor”, i.e. the task of the corridor, in which the respondent should be laid, is repeated, repeating the presented (reproducible) stimulus. If the respondent “strongly” gets off, then it goes beyond the limits of the given corridor, which is set by the operator. T Average interval period seconds Duration of the intervals of the setting rhythm reproducible by the respondent. ϬТ Standard deviation T (average period interval) seconds The scatter of the values of the interval period in the entire series; reflects the stability of the rhythm reproduced by the respondent. ν The average frequency of the intervals reproduced by the respondent beats / min The reciprocal of T (the average period of the interval). Ϭν Standard deviation ν (average frequency) beats / min Indicator of frequency variation in the entire series; reflects the stability of the rhythm
(the standard statistical indicator characterizing the task performance: the better the task is performed, the smaller the spread). In the particular case is an analogue of sustainability. Sc The standard deviation of the intervals reproduced by the respondent from the given one. seconds Reflects the quality of falling into a given rhythm. V The variation of the intervals reproduced by the respondent from a given (= Sc / Tz), where Tz (T set) is the interval of the rhythm specified by the metronome. dimensionless Reflects the quality of falling into a given rhythm, reduced to frequency.
With a rhythm of 60 sound stimuli / min Sc = V. τ index The ratio of the average duration of the intervals reproduced by the respondent to the given (represented by the respondent) duration of the intervals (= Т / Тз). dimensionless τ> 1 - the intervals reproduced by the respondent are longer than the specified one, that is, the responding rhythm is reproduced more slowly by the respondent than is needed, the respondent lags behind the rhythm
τ <1 - the intervals reproduced by the respondent are shorter than the specified one, that is, the responding rhythm is played back faster than necessary, the respondent accelerates, is ahead of the rhythm setting ε-error Average relative reproduction error (= τ-1).
For a rhythm set by (a metronome), the period and interval are identical (equal). For the rhythm reproduced by the respondent, a definition is used — an interval that differs from the period, since the respondent may not accurately reproduce the rhythm presented to him. dimensionless positive - at τ> 1 (deceleration);
negative - when τ <1 (acceleration) M-error The average absolute deviation of the interval reproduced by the respondent from the specified interval. seconds The measure of the accuracy of hitting the rhythm.
M-error is more sensitive in the case of an average person getting into a rhythm, but in some cases deviating strongly from it.

Also, in the process of the aforementioned registration by the percussion module 110, the transmission of the recorded (recognizable) rhythm setting signals begins. and in the sound card 120. In the particular case, in step 320, the percussion module 110 initiates the recording of the repetition of the master rhythm by the respondent, and the respondent repeats the master rhythm by hitting the percussion module 110, and the transmission of the registered master rhythm signals to the sound card 120 begins, the percussion module 110 performs recognition of the response signals of the respondent to the specified rhythm by striking the percussion module 110.

Next, in step 325, sound card 120 starts recording the recorded (recognizable) signals, in particular, the stereo signal (stereo sound, two audio signals, two sound signals, the signal on two audio channels) to the personal computer 130, and the transmission of the recorded (recognizable), in particular recorded by sound card 120, signals to (c) personal computer 130, in particular, into a software module that converts recognized signals into a universal format (form) 220 and / or into a software analysis module and representations 230, and / or to the storage device of the personal computer 130, wherein the first audio signal (in particular, the rhythm audio signal, for example, the master rhythm audio signal) is recorded into one recording channel, in particular, the audio recording (audio file), and the responder audio response signal (beats percussion module 110, carried out by the respondent) is recorded in another recording channel, in particular, audio recordings (audio file). In the particular case, at step 325, sound card 120 starts recording the repetition signals by the respondent of the master rhythm transmitted to the sound card 120 by the percussion module 110, and the signals of the generated master rhythm and the transfer of the recorded repetition signals of the master rhythm and the signals of the generated master rhythm to the program module converting recognizable signals into a universal format (form) 220 of a computing device, in particular, a personal computer 130.

Next, in step 330, the rhythm 210 generation module completes the generation of the setting rhythm and optionally another rhythm (rhythms) and / or stimulus (s), in particular, at the end of the duration of the setting rhythm, as described in the framework of the present invention. It should be noted that the operator or the respondent can stop the generation of a setting rhythm and optionally another rhythm (rhythms) and / or stimulus (s) in the user interface of the rhythm generation software module 210.

In the particular case, the oscillations of the driving signal on the shown intervalogram are (are) within 5%. In the particular case, when the respondent is presented with an interfering rhythm (which is also recorded and displayed on the intervalogram), the addition of the master rhythm with the interfering rhythm (530) is performed, since in the particular case the interfering rhythm and master rhythm are recorded in one channel, which leads to a change in amplitude signal (in particular, the total signal). It should be noted that, in the particular case, the interfering rhythm and the master rhythm can be recorded in different (different) channels, which allows you to "dissolve" (in particular, record) any sounds, each in its own channel.
