Reflex and reaction time

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.
