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. [20]
Serial reaction time (SRT) is a commonly used parameter in the measurement of unconscious learning processes. [1] This parameter is operationalised through a SRT task, in which participants are asked to repeatedly respond to a fixed set of stimuli in which each cue signals that a particular response (i.e., button press) needs to be made.
Given that the average human reaction time is around 0.2 to 0.25 seconds, the round is over before most people can react. 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.
The Five-choice serial-reaction time task (5CSRTT) is a laboratory behavioral task used in psychological research to assess visuospatial attention and motor impulsivity in animals. [ 1 ] [ 2 ] The task takes place within an operant chamber equipped with at least five holes (apertures) that can illuminate, and a food tray to deliver reward.

Data from W. E. Hick (1952) demonstrating Hick's Law: The relationship between reaction time and number of response options across two participants (red and blue). Given n equally probable choices, the average reaction time T required to choose among the choices is approximately: = (+)
Experts historically used a reaction time of 0.75 seconds, but now incorporate perception resulting in an average perception-reaction time of: 1 second for population as an average; occasionally a two-second rule to simulate the elderly or neophyte; [Note 4] or even a 2.5 second reaction time—to specifically accommodate very elderly ...
