Answer:
Reaction time
Step-by-step explanation:
In psychology, the term reaction time refers to the amount of time it takes a person to respond to an stimulus. In other words it is the amount of time that passes between the moment the stimulus start and the moment the person reacts to the stimulus.
In this example someone dictates and John and Jean type. However, John types faster than Jean since John responds faster to auditory stimuli than Jean does. In other words, the amount of time that passes between the moment the words are dictated and the moment they start typing is larger in the case of Jean. Therefore, this illustrates the difference in John's and Jean's reaction times.
