Introduction: The present study analyzes the individual characteristics and typology of the basic properties of STS and the bioelectrical phenomena in the brain that arise when solving problems of separate and simultaneous scaling of STI of 5 and 15 sec.
Methods: In 40 conventionally healthy subjects of both sexes, the indicators of the average duration of subjective time intervals were assessed. The deviations of the subjective time from the objective time were compared, the stability of these indicators was determined in 5 repeated tests, and the spectral power density of the electroencephalograms recorded in a single system with measurements of time was calculated.
Results: The results showed that the STS for 5 sec has a smaller deviation of the subjective time intervals from the objective time and has a greater variability of indicators in repeated tests compared to the STS for 15 sec. With the interaction of STS, the duration of the subjective time increases and approaches the objective one for both scales.
Conclusion: We present individual characteristics of the subjects on the basis ofcluster analysis of subjective time intervals deviations from the objective time are grouped into 2 psycho-physiological time scaling profiles. The profiles differ in the bioelectrical activity of the brain: The EEG spectral power in the studied frequency range is higher in representatives of the second profile both with separate and simultaneous time scaling.
