Document Summary
Rt is defined as the time interval between the presentation of a signal (such as a light or an auditory tone) and the initiation of movement. (b) give an example of when rt can be used. Choice reaction time is when there are many possibilities for action available, discrimination reaction time is when multiple signals are presented. (b) give an example for each. Choice reaction time- quarterback can throw to anyone or run with the ball. Fractionated reaction time (frt), requires the use of surface electromyography (emg) to partition. Premotor time is the time that elapses between the presentation of a reaction signal and the first change in emg activity in the muscle that is identified as the prime mover in the action being observed. Motor time begins with the first change in electrical activity recorded in the prime-moving muscle and continues until the movement begins.
