Abstract:
Rationale for choosing. An increase in physiological tremor (Tr) in emotionally
saturated situations is reflected not only in fiction, but also in scientific literature. In other
words, tremors and emotional responses are interconnected. Purpose. To investigate the
reflection of individual-typological properties in a tremorogram using V. M. Rusalov’s
mathematical modeling. Material and methods. Tr was recorded using a linear transducer.
Tr was recorded under postural load (arms extended forward). The sensor was alternately
placed on the outstretched right and left arms in front of oneself, under conditions of “eyes
open” (operative rest). The analysis of the tremorogram (TrG) files was carried out after the
end of the study using the "Analist - 2" software according to the half - period analysis algorithm. To study the individual psychological characteristics of the personality, we used
the method of determining the properties of the temperament by V.M. Rusalov. Each of the
many indicators of Rusalov’s test selected in the analysis was considered as a target feature
(Y-s), and the amplitudes and frequencies of TrG were considered as influencing variables
(sets of X - s) and multiple linear regression equations of the form were built: The parameters
of the amplitude and frequency of EEG rhythms were used as Xs. Own research. In multiple
regression analysis of the influence of TrG indices of the right hand on the indices of
Rusalov’s test, 12 statistically significant regression coefficients were determined, and 11
statistically significant regression coefficients for the left hand. After obtaining the diagnostic
equations of multiple linear regression, describing the influence of TrG indicators on the
indicators of Rusalov’s test, an attempt was made, using these equations, to obtain the
indicators of Rusalov’s test, using the tremor indicators. On average, the% discrepancy
between the determined and predicted indicators was 97.42% for the right hand, and 101.98
for the left. Conclusions. 1. With the use of diagnostic equation, it was possible to predict the
indicators of psychological testing according to Rusalov’s test by the indicators of tremor of
the right and left hands.
2. Influence of Rusalov’s test indicators on TrG indicators were less in modulus than
the influence of TrG indicators on the indicators of Rusalov’s test, i.e. did not participate in
the control of the mechanisms of TrG generation.
3. The results obtained indicate that tremor indicators contain information about the
subject-activity and communicative aspects of temperament according to V. M. Rusalov.
