Describe an experiment to test someone’s reaction time.
E.g. One person holds a ruler vertically between the thumb and forefinger of the person being tested. Then they let go without giving any warning. The person being tested tries to catch the ruler as quickly as they can. Reaction time is measured by how far down the ruler is caught. The further down it’s caught, the slower their reactions.
