Have you ever sat in your car at a stoplight trying to predict the exact moment the light will change? You might say that these tests are for the easily amused -- those of us who can become surprisingly absorbed in even the simplest games. These reflex tests are very simple, and yet strangely captivating. Scientific tests have also shown that reaction times to simple tasks have high correlations with g the general intelligence factor.


Colors
Simply click the start button and wait for the screen to change color. As soon as it does, click the stop button. The Tester will report how quick your response time was (along with a snide remark challenging you to do better). If you think it will make any difference, you can choose from a list of background colors. Good luck!

Stop the Clock
Stop the counter as close to 500 as possible.
