METHOD FOR IDENTIFYING SPACE AND TIME DISTRIBUTION OF HUMAN ATTENTION IN RESPONSE TO STIMULATION HAVING SIX TO EIGHT ALTERNATIVES

摘要

FIELD: medicine. SUBSTANCE: method involves evaluating sympathico- parasympathic balance index (SPBI) value from R-R interval distribution as ratio of two parameters: mode amplitude (MA) to number of positions (N) forming the distribution. Logarithmic scale is used. R-R interval estimate resolution capacity is defined to be equal to 0.01 s. Positive value and magnitude of the SPBI determine domination and domination measure of sympathic component of organism cardiovascular system, respectively. Negative value and magnitude of the SPBI determine domination and domination measure of parasympathic component of organism cardiovascular system, respectively. R-R interval distribution median frequency (F_me, Hz) is evaluated. A patient is identified with respect to his individually typological cardiovascular activity specific features by means of two-dimensional plane vector coordinates, where SPBI is the ordinate (conditional units, logarithmic scale), and apex is the R-R interval distribution median frequency (Hz) in (100x5) cardiocycles. Attention distribution level evaluation is carried out by means of modified version of known methods united under the common name of "correction tests". Cardiovascular activity types of an organism are set in correspondence to different time-and- space distributions of human attention in response to stimulation with six-to-eight alternatives. EFFECT: unbiased evaluation of human attention properties.
