The pathway of a series of neural processes in a human body is called as a reaction rate .The reaction rate of a human male and female is slightly more in males than in females .
Theoretical minimum reaction time is between 150 and 200 milliseconds.
My average reaction time is 0.386 seconds.
The difference between the two numbers is the first number is the standardised 150 to 220 milliseconds and the second number is the average reaction rate when my nerves or the muscles react to any simple stimulus.

Phy 1010 – Chapter 2 Activity: Measure your reaction time. Requires a ruler and a friend to help you. Hold the index finger and thumb of your dominant hand about 2.5 cm apart, and have a friend hold a ruler vertically in the space between your fingers and thumb. Note the position of the ruler relative to your index finger. Your friend must release the ruler, and you must catch it (without moving your hand downward) as quickly as you...

9. In a human factor experiment project, it has been determined that the reaction time 2 of a pilot to a visual stimulus is normally distributed with a mean of 1/2 second and a standard deviation of 2/5 second. Let n(q;M, 0) represent the probability density function. (a) Set up the integral that would calculate the probability that a reaction from the pilot takes more than 0.3 second. (b) Set up the integral equation that would calculate the reaction time...

3. Reaction time experiment (L. Cai, T. Li, Nishant, and A. van der Kouwe, 1996) The experiment was run to compare the effects of auditory and visual cues on speed of response of a human subject. A personal computer was used to present a "stimulus" to a subject, and the reaction time required for the subject to press a key was monitored. The subject was warned that the stimulus was forthcoming by means of an auditory or a visual cue....
