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 ...
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. The computer measures the time the ...
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.
The Cambridge Neuropsychological Test Automated Battery (CANTAB), [1] originally developed at the University of Cambridge in the 1980s but now provided in a commercial capacity by Cambridge Cognition, is a computer-based cognitive assessment system consisting of a battery of neuropsychological tests, administered to subjects using a touch screen computer.
It is a computer-aided cognitive assessment system consisting of a battery of neuropsychological tests, administered to subjects using computer screen, a dedicated keyboard and a graphics tablet as stimulus and response media, respectively. The nine tests in CFS examine various areas of cognitive function, including:
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.
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.
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]
