discrimination reaction timer

A discrimination reaction timer is a device used in laboratory research to measure an individual's ability to respond quickly and accurately to specific stimuli. This type of timer is often employed in studies of psychomotor learning, where researchers aim to quantify how well a person can make prompt, synchronized adjustments in response to visual cues.12

For example, a discrimination reaction timer might require a participant to quickly flip a toggle switch when they see a particular pattern of colored lights. The speed and accuracy of these responses provide data on the individual's reaction time and their ability to discriminate between different signals.21
