[Relation between reaction time and the characteristics of a motor act].
The connection of reaction time (RT) with spatial-temporal motor parameters was studied in humans. Duration of the motor act was set by experimenter. In response to the signal the tested person pressed one or two buttons according to instruction. The interval between these pressings corresponded to the time of performing the movement. It is shown, that RT significantly depends on the regime of work, duration of movement, and distance between buttons: with greater distances such dependence becomes significant. It is suggested that dependence of RT upon various motor act parameters is determined by differences in the levels of brain structures activation and in spatial-temporal organization of the movement.
