Which test is commonly used to measure reaction time?

• A. Ruler-drop test
• B. Stork balance test
• C. Push-up test
• D. Vertical jump test

Answer: (A)

Reaction time is how quickly you respond to a stimulus. The ruler-drop test captures this by releasing a ruler without warning and asking you to catch it as quickly as you can. The shorter the distance the ruler falls before you catch it, the faster your reaction time, because the time between sensing the cue and starting the catching motion is smaller. The test is simple, requires minimal equipment, and directly gauges the speed of a quick perceptual-motor response.

The stork balance test, by contrast, measures balance and stability rather than how fast you react. The push-up test assesses muscular endurance and strength, not reaction speed. The vertical jump test evaluates leg power and explosive strength, not the speed of responding to a cue.
