The reliability of reaction time determinations.
The reliability of simple and two-choice reaction time (RT) as a function of number of trials and measure of central tendency was examined. It was found that, within the particular conditions of the study, 18 trials were sufficient to obtain a highl reliable determination of simple RT but 30 trials were required for a highly reliable determination of two-choice RT. The selection of measure of central tendency was not related to degree of reliability.
