FIELD: medicine. SUBSTANCE: method involves recording percipient brain activity encephalogram and carrying out encephalogram alpha rhythm analysis by performing a series of 30-50 percipient alpha rhythm measurements free of inductor influence and a series of 30-50 alpha rhythm measurements under conditions of inductor influence. Every measurement is accompanied by calculating standa Аeviation of alpha rhythm oscillation amplitude. Reliable difference being detected, influence effectiveness is determined from the ratio of alpha rhythm signals standard deviation in series of measurements under inductor influence and alpha rhythm signals standard deviation in series of measurements under condition of no inductor influence exerted. EFFECT: enhanced accuracy in determining mental influence effectiveness of inductor operator. 2 cl, 1 dwg, 3 tbl
