We have studied the influence the individual characteristics of the electroencephalogram and psychological characteristics of the subjects, such as the level of attention, anxiety, neuroticism on the reaction time. It has shown that the choice reaction time associated with the parameters of the electrical activity of the brain, while the time of simple sensorimotor reaction more associated with the psychological state of the subject at the time of the observation. The subjects, who had higher levels of neuroticism and level of reactive anxiety, longer reacted to the stimulus in the case of simple sensorimotor reaction. Choice reaction time is the less, if the frequency of the alpha rhythm is the more and amplitude of the alpha rhythm is the smaller. High diversity of periodic regimes of brain increases choice reaction time and , at the same time ensures its stability. It has also shown that reaction time is more accurate and stable in several variants of the experiment, if the frequency of the alpha rhythm in the electroencephalogram and the level of attention of the subject were higher.
