Lyndsey Nickels was supported by an Australian Research Council QEII fellowship during preparation of this paper. Thanks to Anna Woollams for programming the DMDX software, to Carl Windhorst for help running the experiments, and to Britta Biedermann for some of the analysis. Two reviewers provided helpful comments on an earlier draft and David Howard suggested the inclusion of effect sizes and their relationship to mean RT.
