Choice Reaction Time (CRT)

To take advantage of extra outcome measures and our latest cloud technology, we would recommend using our Reaction Time task.

Choice Reaction Time tests general alertness and motor speed. It is a 2-choice reaction time test, similar to the Simple Reaction Time task, however stimulus and response uncertainty are introduced by having two possible stimuli and two possible responses.

Administration time

7 minutes

Task format

An arrow-shape is displayed on either the left or the right side of the screen.

The participant must select the left-hand button if the stimulus is displayed on the left-hand side of the screen, and the right-hand button if the stimulus is displayed on the right-hand side of the screen.

Outcome measures

Outcome measures assess correct and incorrect responses, errors of commission and omission (late and early responses), and latency (response speed). 

Normative data
