FIELD: medicine. ^ SUBSTANCE: invention relates to medicine and is intended to determine time for training on how to assess time of visual information sensing. The tested person is exposed to sequence of two light pulses with duration of 50 ms separated by pause with duration of 150 ms, repeating via constant time interval of 1.5 s. At the first stage duration of pause is reduced with speed of 20 ms/s, at the second stage duration of pause is increased with speed of 5 ms/s, at the third stage of measurements duration of pause is reduced with speed of 1 ms/s, until the tested person determines moment of subjective merger or separate perception of two light pulses. Time of visual information perception is accepted as equal to value of sum of duration of light pulse and duration of pause at the moment of subjective merger of two light pulses into one, determined at the third stage. It is marked on plane in coordinates "value of time for visual information perception - number of measurement". Procedure is repeated, curve is built for dependence of visual information perception time values as function tvip=f(Ni), where Ni - number of i measurement, i=1, 2,Ç, k, k - number of measurements, until quasistationary mode is obtained. Time of training is determined by number of measurements performed during transition process. ^ EFFECT: method expands arsenal of facilities for determination of visual information perception time assessment. ^ 5 dwg, 2 ex |
