Choice reaction time (CRT) is a computerized assessment that trains the subject in holding down a press-pad and releasing the press-pad in response to stimuli presented on the screen. The task requires the subject to react as soon as a yellow dot appears in one of five locations, and the subject must respond by lifting their hand from the press-pad. This is the reaction time (RT) and ranges from 100 to 5000 msec. Lower scores indicate better performance.
