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.

Visual representation of the hypothesized stages of a reaction time task and each stage's association with diffusion model parameters. T er, the non-decision reaction time component, consists of the sum of encoding time T e (first panel) and response output time T r (third panel), such that T er = T e + T r.
A psychomotor vigilance task (PVT) is a sustained-attention, reaction-timed task that measures the consistency with which subjects respond to a visual stimulus.Research indicates increased sleep debt or sleep deficit correlates with deteriorated alertness, slower problem solving, declined psychomotor skills, and increased rate of false responses.

Stimulus–response (S–R) compatibility is the degree to which a person's perception of the world is compatible with the required action. S–R compatibility has been described as the "naturalness" of the association between a stimulus and its response, such as a left-oriented stimulus requiring a response from the left side of the body.
A study from 2008 suggested that differences may occur early during development. The experiment was done on 3- to 4-month-old infants using a 2D mental rotation task. They used a preference apparatus that consists of observing during how much time the infant is looking at the stimulus.
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.
