WebThe ratio of brake reaction time 3 to brake reaction time 2 was used as a correction factor and applied to brake reaction time 1. The corrected median of the resulting distribution … WebWhat Is a Normal Reaction Time? The normal reaction time, like most other things about the human body, is not constant.It differs from person to person and also depends on what sensory regime the stimulus belongs to. Here’s a generalized estimate of average reaction time for various stimuli: . Average visual reaction time is 0.25 seconds.; Reaction time …
