FIELD: medicine.SUBSTANCE: invention relates to medicine, psychophysiology, psychology, sociology and pedagogy, and can be used to determine the typological features of the properties of the human nervous system on the basis of an evaluation of the ability to reproduce time intervals. Tests are performed in two stages. Subject repeatedly, in the range of short 2–5 s and long 8–12 s segments at the first stage, selects the reference time interval, then reproduces it from memory: first longer, then shorter than the reference. Then after selecting the reference time interval, the subject reproduces it: first shorter, then longer than the reference. At the second stage, the subject selects the reference interval and then repeats it from memory as accurately as possible. Based on the results, depending on the magnitude of the deviations during reproduction of the reference intervals by the subject, the mobility of the processes of excitation and inhibition and the "external" and "internal" balances of the nerv
