Reaction Time Exercise - How Fast Are You?
- measurement of reaction time
- effect of body part on reaction time
- effect of distance on reaction time
- effect of weight on reaction time
- effect of gender on reaction time
Measure reaction time as the distance that a ruler drops before a subject can grasp it
- Position the subject with the elbow at the side of their body,
their forearm horizontal and semipronated
- Hold a ruler even with (long axis up/down) even with the top of the subjects
thumb and forefinger
- Instruct the subject to catch the ruler when you release it
- Calculate the reaction time from the distance that the ruler drops (t=(2d/g)0.5)
Reaction Time Caluclator:
- distance between fingers)
- counting down
- Compare the reaction times across conditions.
Explain the difference between each condition.
- List the physiolgical events that occur as when
subjects try to catch the dropping weight?
- Can you redesign this task to improve a workers performance?
- How much time would ou need to reach and grasp a hand hold if you slip?
