Description

 The invention relates to medicine, namely, it is used in psychotherapeutic practice for conducting psychological diagnostics, identifying and studying semantic constructs with the aim of suggestive, corrective, therapeutic and rehabilitation effects on the psychophysiological state of the person being examined.

 Known methods of transforming verbal audio information to create unconscious suggestion that allows you to influence the psychological setting of a person, change his attitude to certain frustrating situations.

 There is, for example, a method of stimulating and generating an altered state of consciousness (WO 90/01967, 03/08/90), in which verbal audio information is superimposed on a noise signal and after wave modulation is fed through a headphone to an auditory analyzer, while the patient can only be hardly heard distinguishable, or completely indistinguishable words. This transformation of the signal increases the hemisphere susceptibility to information. However, the fact of the presence of a voice message is detected by the subject, which reduces the removal of control of consciousness and worsens the results of the introduction of suggestive information.

 Also known is the speech coding method, selected as a prototype, developed by E. Taylor (E. Taylor, "Subliminal Communication", US, Las Vegas, 1990, pp. 35 - 37, 72 - 73), including the transformation of verbal audio information to the subthreshold level perception by combining the background audio signal (for example, music fragments, wind sounds, water noise or white noise) and an information signal containing verbal information and bringing them to the subject's auditory analyzer or groups of subjects. The information signal is preliminarily converted according to a number of parameters, in particular, in amplitude, or is harmonized in voice frequency with the background audio signal, or verbal audio information is coordinated with the frequencies of musical instruments. The test result is recorded according to the electroencephalogram (EEG). The known method changes the characteristics of the acoustic signal in such a way that the verbal suggestive information contained in it, in principle, cannot be perceived at a conscious level. However, the technical methods used for converting information and summing the signals used in this way distort the background signal itself, which ultimately reduces the significance of perceived verbal information.

 The objective of the proposed method is the transformation of the verbal audio signal to the pre-threshold level, which allows you to remove control of the test person’s consciousness and “bypass” the psychological defense mechanism, enhance the assimilation of information and expand its level of perception. In addition, registration of a number of bioelectric indicators will allow organizing biological feedback to optimize the signal transformation program.

 The essence of the method lies in the fact that they combine the background signal and the converted information audio signal, the latter contains verbal information, brings them to the auditory analyzer of the person being examined, and records its bioelectric indicators. In this case, the information signal is preliminarily analyzed spectrally with the separation of the main formants and overtone components of the fundamental tone, multi-stage transformed by amplitude-phase modulation of the main formants, compression of the frequency spectrum with simultaneous lengthening of vowels and limitation from above and below the frequency range, the combination of audio signals is carried out at a constant ratio the power of the information signal is lower than the background and the electroencephalogram (EEG), ECG and respiration indicators, etc. They are processed and introduced into the corrected information signal.

 As a background audio signal, it is possible to use musical fragments or sounds of nature, folk, traditional lullabies and ritual tunes, as well as spontaneous noise.

 The duration of the sound of the verbal formula of the information signal can be no more than 1 minute.

 To expand the scope of use of the method, a limited frequency range is equal to the range of transmission frequencies of telephone lines.

 The ratio of the power of the information signal to the background is 0.15 - 0.25.

 The transformation method is aimed at studying the psychosemantic spaces of human memory by computer modulating auditory verbal stimuli at a subthreshold level, perceiving and recording changes in EEG and a number of other parameters in response to a combination of physical (acoustic) and semantic effects (in the form of verbal formulas of suggestion, transformed for subthreshold perception ) in the biofeedback mode (BFB), when the measurement results can be entered into the corrected information signal l.

 The method is as follows.

 Electrodes are superimposed on the subject, mainly according to the standard international circuit 10 - 20. Active electrodes are placed at points F3, F4, T3, T4, P3, P4, O1, O2. Indifferent electrodes are placed on earlobes or on mastoids. Electrodes for recording eye movements are located above the superciliary arch and near the outer corner of the eye, etc. Measured bioelectric parameters are visualized. The subject is put on headphones, a blackout is created and the research program is launched. In this case, the input information is the processed data of the state indicators, and the output is a certain algorithm for changing the phonostimulation parameters.

 At the first stage of the study, the test subject develops a state of relaxation. In this case, meditative music, music and the words of old lullabies, preferably of the nationality and culture with which the subject is identified, natural or optimized phonograms of the splashing of sea or river waves, the sound of rain, wind, etc. are used as the background audio signal. In this case, the EEG and ECG reference data are accumulated.

 At the second stage, the background audio signal is combined with the processed information signal. An unconscious audio suggestive signal is built on the basis of an integrated analysis of the data obtained in the first stage, and the selection of options for verbal blocks-blanks, the most effective in each case. For example, for subjects who have disorders of the anxiety series, one of the initial options for outgoing verbal suggestion blocks may be the spectrum of several types of phrases “Easy, free, calm.” In a transformed form, information can retain an emotional tone.

 The information signal is spectrally analyzed with the release of the main formants and overtone components. A multi-stage conversion is carried out with amplitude-phase modulation of the main formants, compression of the frequency spectrum while lengthening vowels and limiting the frequency range from top to bottom, mainly to harmonize the frequency range with the frequency range of telephone lines, which greatly expands the diagnostic range. As a result of encoding a speech signal, the original signal turns into a kind of "white noise", and the combination of audio signals with a constant power ratio of information and background signals of the order of 0.15 - 0.25, the meaning of the speech message is not recognized at a conscious level, as well as the fact of its availability.

 As a result of the work of the neurophysiological mechanisms of the brain, such information is embedded in the psychosemantic spaces of memory, decoded and assimilated. The verbal information used in this case consists in the use of short formulas, sounding no more than 1 minute, consisting of two to three phrases pronounced in the mother tongue of the person being examined, looped for repeated presentation.

 To increase the effectiveness of suggestive psychocorrectional effects, associative connections are used that are oriented to archetypal psychosemantic memory spaces (fairy tales, ritual or lullaby songs, sayings, etc.) and sound rhythmic action.

 In the recorded bioelectric parameters, the presence of amplitude artifacts is controlled, the results are processed, correction and rhythm modulation of the information signal is carried out.

 Using a complex of computer psychodiagnostics allows obtaining psychological data on the functional specificity of the structure of psychosemantic memory spaces and, if necessary, optimizing the psychophysiological state of the person being examined. A developed system of registration and stimulation allows multi-parameter feedback - the mapping of electrophysiological parameters into auditory images. Creating a state of increased suggestibility by combining the use of unconscious suggestion with sound rhythm modulation allows us to solve the problem of optimizing the psychophysiological functional state of a person.
