Reaction time (RT; also referred to as "response time") is measured by the elapsed time between stimulus onset and an individual's response on elementary cognitive tasks (ECTs), which are relatively simple perceptual-motor tasks typically administered in a laboratory setting. [1]
Simon wished to see if an alteration of the spatial relationship, relative to the response keys, affected performance. Age was also a probable factor in reaction time. As predicted, the reaction time of the groups increased based on the relative position of the light stimulus (age was not a factor). The reaction time increased by as much as 30% ...
Saccadic reaction times (SRTs -- time it takes for you to looks at something that appears in the periphery). Incidentally, in humans these tend to be between 110 and 150 ms (depending on what you're looking at when the stimulus is presented), but can drop as low as 70 ms in some circumstances.

Exceptions to Hick's law have been identified in studies of verbal response to familiar stimuli, where there is no relationship or only a subtle increase in the reaction time associated with an increased number of elements, [5] and saccade responses, where it was shown that there is either no relationship, [6] or a decrease in the saccadic time ...
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.
A millisecond (from milli-and second; symbol: ms) is a unit of time in the International System of Units equal to one thousandth (0.001 or 10 −3 or 1 / 1000) of a second [1] [2] or 1000 microseconds.
Here, the critical parameter is the time interval (the SOA) between the onset of the subliminal stimulus and the onset of the masking stimulus. [1] In psycholinguistics the stimuli are typically a prime and a target, in which case the stimulus-onset asynchrony is measured from the beginning of the prime (S1) until the beginning of the target (S2).
