[The dependence of the achievement of students on the individual typological properties of their nervous systems].

A reliable correlation (r = 0.47) between cognitive ability and educational achievement has been determined in 195 students (men and women) aged 21-25. Progress in studies depends also on such individual-typological properties as "strength" of the excitation process (r = 0.46), work reliability (r = 0.49) and functional "mobility" of the nervous brain process (r = 0.38). On the whole, teaching efficiency is determined by a complex of psychophysiological state indices rather than by one of these indices.
