Record the point at which you caught the ruler, to the nearest cm. Measure from the bottom of your thumb. You can use this table to convert the measurement on the ruler into your reaction time in seconds. The less time it takes you to catch the ruler, the faster your reaction.Reaction time tests measure the time it takes for an individual to respond to a stimulus.
