Using the jackknife-based scoring method for measuring LRP onset effects in factorial designs.
Miller, Patterson, and Ulrich (1998) introduced a jackknife-based method for measuring the differences between two conditions in the onset latencies of the lateralized readiness potential (LRP). TheExpand

Testing the race model inequality: An algorithm and computer programs
In divided-attention tasks, responses are faster when two target stimuli are presented, and thus one is redundant, than when only a single target stimulus is presented. Expand

Mental chronometry and individual differences: Modeling reliabilities and correlations of reaction time means and effect sizes
We used a general stage-based model of reaction time (RT) to investigate the psychometric properties of mean RTs and experimental effect sizes (i.e., differences in mean RTs). Using the model,Expand

Perceived duration of expected and unexpected stimuli
Three experiments assessed whether perceived stimulus duration depends on whether participants process an expected or an unexpected visual stimulus. Participants compared the duration of a constantExpand

Use of illicit and prescription drugs for cognitive or mood enhancement among surgeons
BackgroundSurgeons are usually exposed to high workloads leading to fatigue and stress. This not only increases the likelihood of mistakes during surgery but also puts pressure on surgeons to useExpand

Threshold estimation in two-alternative forced-choice (2AFC) tasks: The Spearman-Kärber method
The Spearman-Kärber method can be used to estimate the threshold value or difference limen in two-alternative forced-choice tasks. This method yields a simple estimator for the difference limen andExpand
