Abstract

A potential undesirable effect of ignoring aberrant response times (RTs) in educational and psychological tests is increased bias in estimation of parameters of interest. This study proposes four significance testing procedures for identifying aberrances in RTs obtained from individual test takers. The procedures are formalized using the posterior density for a speed parameter or posterior predictive distributions of RTs.
