| Simple Reaction Time (SRT) is a test which measures simple reaction time through delivery of a known stimulus to a known location to elicit a known response. The only uncertainty is with regard to when the stimulus will occur, by having a variable interval between the trial response and the onset of the stimulus for the next trial. Like Choice Reaction Time (CRT) it is useful for testing general alertness and motor speed, and is often sensitive to medication effects. |
