My reaction time: 018 seconds 1 if you are traveling at a velocity of 100km/h convert this velocity to m/s 2 how far would your car travel during the time it takes you to react.
Mental chronometry is studied using measurements of reaction time (rt), which is the elapsed time between the presentation of a sensory stimulus and the subsequent behavioral response in psychometric psychology it is considered to be an index of processing speed [1. Home info car insurance info the science of drunk driving the science of drunk driving motor skills and a reduction in reaction time the science. Simple reaction time (srt), the minimal time needed to respond to a stimulus, is a basic measure of processing speed srts were first measured by francis galton in the 19th century, who reported visual srt latencies below 190 ms in young subjects however, recent large-scale studies have reported. Human reaction time (rt) can be defined as the time elapsed from stimulus presentation until a reaction/response occurs (eg, manual, verbal, saccadic, etc.
One of the most investigated factors affecting reaction time is 'arousal' or state of attention, including muscular tension reaction time is fastest with an intermediate. A tactile reaction time is the reaction from the sense of touch this is slightly different to the pain reaction time as touch and pain receptors aren't exactly the same tactile reaction erne is used when the stimuli physically touches you such as if somebody were to touch you on the back. The science suggests that human reaction time is an indicator of a body with better system integrity the master control centre for your reaction is, of course, your brain in a split-second it.
