The method of brief PSIs (precue-to-stimulus intervals) was used in three RT (reaction-time) experiments to explore the generality of the precue-utilization effect in rapid reactions, and to examine two extensions. This effect, which shows the self-contained performance in the choice reaction of the processing operations that culminate in response selection, generalized to a quantitative discrimination and to unequal stimulus-response (SR) frequencies. In the first extension, the reduction in wrong-alternative errors at relatively long PSIs indicated that these errors occur in conjunction with commitment to response actualization. In the second extension, the duration of discrimination-selection was found to be no longer for the less frequent of two SR alternatives. Taken together, these findings indicate that the effect of relative SR frequency, on incidence of errors as well as length of RT, fell on response-actualization processing. This is in accord with a number of previous findings and consonant with effects of RT variables on movement parameters but contrary to cumulative speed-accuracy models.
