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, operability of PC 4 and touch electronic tablet 6 are checked. From PC 4, commands for setting the gain and frequency bands are written to microcontroller 5 each channel of a multi-channel amplifier 2.

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 by 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 method is based on a joint analysis of trends in physiological parameters and parameters of behavioral activity when performing specific tasks of diagnostic scenarios with a special pen - a pen-pointer on a regular sheet of paper (a familiar technology for any subject), which is placed on a touch electronic tablet connected to a personal computer.

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.
