The Drop Ruler Test is performed using a long ruler or measuring stick, and it leverages the principles of gravity to measure the reaction time of an individual . Del Rossi S. Practice effects associated with repeated .Context: Researchers have confirmed that the ruler-drop test could be included as part of a multifaceted concussion-assessment battery and potentially as a way to track recovery from head injury. However, it is unclear if this clinical test of reaction time would be characterized by inconsistent performance because of practice effects. It includes the ruler drop test (RDT) as a test of RT to be conducted when the suspect is produced before the medical officer in a government hospital. 10 RDT is a simple test of visual reaction time in which the subject attempts to stop a falling ruler. 13 The height the ruler falls determines the time taken to react to the event.
To allow RT assessment in a wide variety of circumstances, we developed a simple, computer-independent clinical measure of RT by standardizing the simple “ruler drop test” that has long been used in physics classrooms to teach students the relationships between distance, acceleration, and time for a free-falling body (Chudler, 2009).

The ruler drop test is a way to determine reaction time using nothing but a ruler and simple math. Find out how to calculate reaction time and the different formula parts required to give an .Practice holding the ruler with those two fingers. 5. Your partner will take hold of the ruler and ask you to remove your fingers. 6. Your partner will hold the ruler so the zero mark is level with the top of your thumb. They will tell you to prepare to catch the ruler. 7. Your partner will then drop the ruler without telling you. 8.
Briefly, this test uses a 'ruler-drop' paradigm to measure simple reaction time, and go/nogo reaction accuracy under time pressure (i.e., the decision to grasp the stick or let it fall must occur .
To measure reaction time, you will use the ruler drop: an experiment that measures how fast a person can catch a dropped ruler. This process is illustrated in Figure 1 and will be explained more later. Figure 1. An illustration of the ruler drop.
