Abstract: It was the purpose of this study to investigate the effect selected durations of PS and RS had on simple RT in a simple RT task. The hypotheses investigated were: (1 ) PS durations of one and four seconds would produce significantly different RT, (2) RS durations of 100 and 300 msec, would result in significantly different RT, (3) the interaction of PS and RS would significantly affect RT. The subjects were 18 male undergraduate students with a mean age of 20 years, enrolled at the University of North Carolina at Greensboro. Subjects were selected at random from a listing of male students in the freshman, sophomore, and junior classes at the University. Each subject was tested under four task conditions in which the PS and RS durations were varied. A total of 160 trials with 40 trials randomly arranged in each condition were completed by each subject. The Hunter Model 120 A Klockounter, a constructed control unit to record RT, a unit to control PS and RS durations, and a response key comprised the instrumentation.
