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. 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 ...
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.
Posner cueing task. The Posner cueing task, also known as the Posner paradigm, is a neuropsychological test often used to assess attention. Formulated by Michael Posner, [1] it assesses a person's ability to perform an attentional shift. It has been used and modified to assess disorders, focal brain injury, and the effects of both on spatial ...
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.
Stroop effect. Naming the displayed color of a printed word is an easier and quicker task if the word matches the color (top) than if it does not (bottom). In psychology, the Stroop effect is the delay in reaction time between congruent and incongruent stimuli. The effect has been used to create a psychological test (the Stroop test) that is ...
Simple reaction time correlates with general cognitive ability, and there is some evidence that the slope of responding on the Jensen box does as well. 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]
Hick's law. 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. The Hick–Hyman law assesses ...
Unlike the marshmallow test, delay discounting does not require verbal instruction and can be implemented on non-human animals. Go/no-go and stop-signal reaction time tasks. Two common tests of response inhibition used in humans are the go/no-go task, and a slight variant known as the stop-signal reaction time (SSRT) test.
