WebFigure 2 Generalized reflex arc. Reaction time is the amount of time required for an individual to perceive and respond to a sensory stimulus (such as the act of swinging a bat at a baseball). The average reaction time for a visual stimulus is 200 to 250 ms; for hearing, 150 to 200 ms; and for touch, 130 to 170 ms. WebA reflex arc is the sequence of processes that occurs within a short duration of time in response to the stimulus.
