Simple reaction time correlates with general cognitive ability, [4] and there is some evidence that the slope of responding on the Jensen box does as well. [2] Ian Deary and colleagues, in a population-based cohort study of 900 individuals, demonstrated correlations between IQ and simple choice RTs between –0.3 and –0.5. [ 4 ]
A Jensen box. The Odd-Man-Out Reaction Time test (OMO RT) is a test of reaction times that uses Arthur Jensen's testing apparatus, the Jensen box.The box is normally used for measuring choice reaction times in which the participant in the experiment is tested on their ability to recognize which of the eight lights of the Jensen box is illuminated, as quickly as possible.

Representation of the stages of processing in a typical reaction time paradigm. Mental chronometry is the scientific study of processing speed or reaction time on cognitive tasks to infer the content, duration, and temporal sequencing of mental operations.
The four boxes test is a computer-based test used to measure reaction times. 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.

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.
Hick's law, or the Hick–Hyman law, named after British and American psychologists William Edmund Hick and Ray Hyman, describes the time it takes for a person to make a decision as a result of the possible choices: increasing the number of choices will increase the decision time logarithmically.
