This lab will test your reflexes to sight and sound input. As with most "reflex tests" it is best to perform the measurements several times to gather some statistics.
For the vision test, you need to click the mouse when you see the region turns red.
For the audio test, you need to click the mouse in the "region" when you hear a sound.
You will hear a sound three times and the screen color will change three times during the testing. The order will be random and the time between changes is also random.
Thanks to Raman Phaff for creating this fantastic lab. Shockwave is being phased out as it is no longer supported in modern browsers.
