Both tasks were adapted from the well-known ruler drop test of RT and involve manually grasping a falling vertical shaft upon its release, with the complex task employing a go/no-go paradigm based on a slight cue. In 46 healthy contact sport athletes (24 males; M = 16.3 yr., SD = 5.0; 22 women: M age= 15.0 yr., SD = 4.0) whose sports included .
The results showed that the relative reliability was good for the choice ruler drop (ICC = 0.81), moderate for the dual-task ruler drop test (ICC = 0.70) and discrimination ruler drop test (ICC = 0.72), and good for simple ruler drop test. 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 . Both tasks were adapted from the well-known ruler drop test of RT and involve manually grasping a falling vertical shaft upon its release, with the complex task employing a go/no-go paradigm based .The ruler drop test is a suitable way to measure reaction time for a few reasons. For one, it is a simple test that does not require any special equipment or training. The test can be conducted . anywhere with a flat surface, making it easy to administer. Additionally, the ruler drop test is quick and easy to use, and can be used to measure a .
Download scientific diagram | Ruler drop test, simple testing procedure from publication: Validity and reliability of a ruler drop test to measure dual-task reaction time, choice reaction time and .
Specifically, the measurements used so far include both computer-based and -independent protocols, where a subject’s fine motor control movement task has been used, such as to press a button or catch a dropped object in response to flashed light (e.g., “ruler drop test”), respectively (Carling et al., 2009; Eckner et al., 2015; Geiger et . The ruler drop test and the Deary-Liewald reaction time test showed reliability. . In the present investigation we studied the relative and absolute reliability and construct validity of a computerized and a hand-RT test. The RDT has been used as an indicator of RT (Johnson and Nelson, 1986), however there are few results available regarding .Ruler drop test. Work with a partner. Person A holds out their hand with a gap between their thumb and first finger. Person B holds the ruler with the zero at the top of person A's thumb.
is the traditional ruler drop test (RDT) and, althoug h the RDT measures RT plus movement time, it continues to be an acceptable means of measuring simple RT (Del Rossi, Malaguti, & Del Rossi, 2014). 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.
Although early research on the ruler-drop test revealed acceptable test-retest reliability 16, 17 and adequate criterion validity in collegiate athletes (r ¼ 0.45), 18 a recent study by MacDonald . One of the simplest and common methods of calculating response time is the ruler drop test. Most of the athletes use this methods to calculate their response time. In our engineering physics class we were asked to use this method to calculate our reaction time. For this assignment we were to be in small groups and measure everyone’s reaction .
Reaction Time: The Ruler Drop Test. The nervous system helps information travel through your body. It consists of the 5 senses, your brain, your spinal column, and the nerves that connect them all together. Suppose your eyes .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.Ruler Drop Test. Testing and measurement are the means of collecting information upon which subsequent performance evaluations and decisions are made. In the analysis, we . Validity. Test validity refers to how the test measures what it claims to measure and the extent to which inferences, conclusions, and decisions made based on test scores .
The ruler drop test measures an athlete's reaction time. An assistant holds a ruler between the athlete's thumb and forefinger while the athlete catches it as quickly as possible when released. The assistant records the distance between the bottom of the ruler and the athlete's thumb. This is repeated three times and averaged. Reaction times are assessed as excellent, above .

The validity of the new VR measurement method was estimated by comparing the results obtained using the computer test and the conventional catch-the-ruler test.
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. In Step 1, one person (the dropper) holds a ruler above the hand of another person (the catcher). The validity of the new VR measurement method was estimated by comparing the results obtained using the computer test and the conventional catch-the-ruler test. The reliability of the measurements was evaluated using an intraclass correlation procedure.

Ruler drop method is an easy to use test and the results of this study provide a normative data for age groups 6–12 years ranging from 214.2 ms to 248.8 ms. These values can serve as a reference to screen children with delayed reaction time. Dropping the same ruler from the same height each time, with the ruler orientated in the same direction (0 cm facing down) If the effect of caffeine is being investigated then none should have been consumed before the start of the experiment, or the room is silent for the first run if background noise is being altered
