The race model inequality for censored reaction time distributions

Abstract

The race model inequality (RMI) introduced in Miller (1982) puts an upper limit on the amount of reaction time facilitation within the redundant-signals paradigm that is consistent with a race model. Here, it is shown through theoretical analysis and numerical simulation that inferences from the RMI test may become invalid when the experimenter misses a proportion of the responses by limiting the recording interval (right censoring) or excluding outliers from analysis (left and/or right censoring). Moreover, a correction of the inequality test for right-censored reaction time distributions is proposed.
