The range of sensory discrimination of a given sense also varies considerably both within and across sensory modality. For example, Kiesow (1903) found in a reaction time task of taste that human subjects are more sensitive to the presence of salt on the tongue than of sugar, reflected in a faster RT by more than 100 ms to salt than to sugar. [20]
The loser of the test received a shock predetermined by their opponent. This test was then repeated however many times to find consistent results. In its current form, the TAP is a computerized task in which the participant competes against an ostensible opponent on a reactive time task incorporated within a computer program utilizing a keyboard.
They suggested that information entropy (H) is a function of the number of alternatives (n) in a choice task, H = log 2 (n + 1); and that reaction time (RT) of a human operator is a linear function of the entropy: RT = a + bH. This is known as the Hick-Hyman law for choice response time. [7]
Task stimuli are presented in a laptop computer and participants respond via 'YES' and 'NO' buttons on a two-button response box, which records both the accuracy and reaction time. The CDR system is a computer based cognitive testing tool, developed to assess both enhancement and impairment of human cognitive performance. The CDR system's ...
Automated Neuropsychological Assessment Metrics (ANAM) is a library of computer-based assessments of cognitive domains including attention, concentration, reaction time, memory, processing speed, and decision-making. ANAM has been administered nearly two million times in a variety of applications and settings.
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. [1]
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 ]
Reaction times: This measures the amount of time between the presentation of the stimulus and the client's response. Omission errors: This indicates the number of times the target was presented, but the client did not respond/click the mouse.
