Operational Definitions Performance is an action that a person attempts in order to produce a voluntary action.
Reaction time is the time from the presentation of a stimulus to the first time of the response.
Practice is when a person repeats a task over and over again. Learning is what is acquired from an initial performance to a final performance. A stimulus is the information that is presented to a subject who then must decide what to do with the information. Hick's Law states that reaction time will increase linearly as the number of stimuli presented is doubled. It deals with the information processing stage because of the amount of information that a performer must deal with before making a decision on what to do.
