| The subject holds his/her hand out, extending the thumb and index finger; a second person holds a 12-inch ruler exactly one inch over the subject's extended hand; the ruler is vertical to the outstretched hand, with the numbers reading from the bottom up. When the ruler is dropped, the subject should be able to grasp it between the thumb and index finger as it drops, without changing the position of the hand or body. The distance that the ruler drops through the fingers before it is caught is taken as the reaction time of the subject. If the subject catches the ruler at 6 inch mark, add 1 inch more to the reaction time to include the space between the ruler and the hand at the start of the trial.
you can calculate your reaction time from this as the ruler is accelerating from 0m/s at a constant rate (due to gravity) of about 9.8(m/s)/s, simple leaving cert formula, of course ive forgotten it, someone look it up in your log tables and post it or something
