Reaction Time

Human reaction time depends very much on the circumstances. E.g. the time that elapses between the driverís perception/decision and the time the brakes are applied or the steering wheel turned is 0.75 of a second for the average person.

The absolute shortest time it takes for a human to react to a sound is 0.110 of a second, based on this if a runner leaves the starting blocks less than 0.1 of a second after the starting pistol is fired then this is automatically called a false start.
