Psychological refractory period between the execution of the first and second task will be absorbed when the interval intervening between the two tasks is long rather than when it is short. Researchers have used the PRP paradigm design to study various topics in psychology, and various results indicate how these areas of psychology are negatively affected by the psychological refractory period delay. PRP is not dependent on "personality". Upon experimentation, participants were tested with a PRP paradigm in which the first task was an auditory task and the second task was a visual two choice task. Results indicated that there is an overall
