TY - JOUR AU - Klemmer, Edmund T. AB - Studied the relationship between reaction time and Ss' uncertainty about the time of stimulus presentation. Reaction time increases with foreperiod variability and with mean foreperiod above an optimum value less than 1 sec. The important determiner of reaction time is not the immediate foreperiod but the distribution of foreperiods within which it is embedded.
