Given n equally probable choices, the average reaction time T required to choose among the choices is approximately: T = b ⋅ log 2 ( n + 1 ) {\displaystyle T=b\cdot \log _{2}(n+1)} where b is a constant that can be determined empirically by fitting a line to measured data.
d PRT = driver perception-reaction distance, m (ft) V = design speed, km/h (mph) t = brake reaction time, in seconds. Based on the results of many studies, 2.5 seconds has been chosen for a perception-reaction time. This time will accommodate approximately 90 percent of all drivers when confronted with simple to moderately complex highway ...
Structurally, the TARA bears some affinities with the implicit association test (IAT), because it generates differences in average reaction time on the basis of differences in response compatibility. The TARA remains to be field-tested.
To measure reaction time (RT), a response mechanism is placed in front of the observer, usually a computer keyboard which is pressed upon detection of a target. Following a set inter-trial interval, usually between 2500 and 5000 ms, the entire paradigm is repeated for a set number of trials predetermined by the experimenter.
In its most commonly used form, the first Damköhler number (Da I) relates particles' characteristic residence time scale in a fluid region to the reaction timescale. The residence time scale can take the form of a convection time scale, such as volumetric flow rate through the reactor for continuous (plug flow or stirred tank) or semibatch ...

In the test, a black circle appears in one of four boxes on the screen, and the patient presses the corresponding key on the keyboard as quickly as possible. The next circle appears after 500 ms, until 52 circles have been exposed. The computer measures the time the subject takes to complete the test and the number of errors they make. [1]
