Reaction Time

This application measures your reaction time. Click the button below to start and wait for it to turn red and then click again. The average reaction time is about 210 ms. You should take the test at least five times to get an average which is more accurate than just a single test. Formally, the reaction time is defined as the time that elapses between presentation of a stimulus (e.g. visual or auditory) and behavioural response.
