Reaction Time

This exhibit allows a person to test his/her reaction time to a variety of stimuli with a very simple device. A stick labeled with time intervals falls at a random time through the fingers of the subject. At the time the stick is released, a light goes out (visual stimulus) and a relay clicks (audio stimulus). The person then tries to grab the falling stick as quickly as possible. The number on the stick under the fingers of the person is the reaction time.
