Visit the following website and follow the directions on screen to complete the The Reaction Time Test | JustPark. Time tends to depend on the speed of the computer and whether the mouse or keyboard is used. Also, times are usually faster when using the keyborad. Record your times for each trial, as well as your ending average time.
Next, ask two other people to complete the exercise and record their times. This can include spouses, family members, friends, co-workers, or whomever you wish. However, make every attempt to ensure that these people differ from you in age. Preferably attempt to recruit people who are 10 years (or more) apart from you in age (either older or younger). Doing so will help you to better answer the required questions.
