The ruler drop test is a simple but accurate way to measure reaction time. This test can be used to determine how fast a person can respond, as well as to measure their reaction time to unexpected events.

Background The aim of this study was to determine the absolute and relative reliability of the Ruler Drop Test (RDT) for assessing dual-task, choice, and discrimination reaction time. In addition, the construct validity of the RDT is examined in comparison to the Deary-Liewald reaction time (DLRT). Methods Tests were administered by the same . The drop ruler experiment tells you that if you stop the ruler at 26 cm, your reaction time is 230 ms. To find this result, consider the equation for the free fall time and follow these steps: Convert the distance to meters, and multiply the distance by 2 :
