The invention can be used to obtain information about a psychophysiological state of a person in different fields, including biometrics, psychophysiology, functional diagnostics and psychology. For this purpose, the following primary psychophysiological characteristics are determined: an energy characteristic, as an indicator of the energy given off by a person, and an information characteristic, as an indicator of the efficiency of information exchange. A person's current psychophysiological state is determined in real time, and additionally the pattern of change in the person's current psychophysiological state over a monitoring period is evaluated. The evaluation of a change in the person's psychophysiological state is carried out in a system of coordinates formed by the primary psychophysiological characteristics, where the pattern of change in the person's psychophysiological state over the entire monitoring period is evaluated according to the change in direction of a vector characteristic in the form of the path of a graph consisting of consecutively interconnected directed segments characterizing the change in direction and magnitude of the primary psychophysiological characteristics for each recorded time interval of the monitoring period. The present method provides an increase in the functional possibilities of a method of evaluating a person's psychophysiological state as a result of the additional analysis of psychophysiological characteristics based on information about the pattern of change in the direction of a vector of the person's unconscious response during the monitoring process, and establishment of a correlation between the change in direction of the psychophysiological response vector and a set of primary physiological parameters determining the person's psychophysiological state.
