The range of sensory discrimination of a given sense also varies considerably both within and across sensory modality. For example, Kiesow (1903) found in a reaction time task of taste that human subjects are more sensitive to the presence of salt on the tongue than of sugar, reflected in a faster RT by more than 100 ms to salt than to sugar.

Performances are also hand-timed and calculated to 1/100 of a second, although studies have shown human beings simply cannot react consistently or accurately enough for this to be a valid method, and even those using light beams are timed by the motion of the athlete, removing the normal factor of reaction time; further, football 40-yard dashes ...
Automatic times start instantly with the sound of the gun, while hand times include human reaction time to start the watch. It took until 1977 before fully automatic timing was required of world records. As the fastest electronic time to that point, Hines' mark was recognized exclusively as a new world record. [5]
The reaction times of the best fast draw shooters is 0.145 seconds, which means that the gun is cocked, drawn, aimed (from the hip), and fired in just over 0.06 seconds. To establish a World Fast Draw Association record, a second shot must be fired in the same competition that is no more than 0.30 seconds slower than the first; this is intended ...
This record is the first time a human has achieved the best result with respect to "frame rules", however there is still time to save in 8-4, the game's final stage. [12] [13] Orland describes Niftski's video showing a heart rate of 188 BPM, and his tearful reaction following the run, telling himself to "Get oxygen, dude". [11]
