The lateralized readiness potential (LRP) is a component of average event‐related potentials that has proven very useful in the study of hand‐specific motor preparation. We developed a model of single‐trial LRP waveforms that produces realistic average waveforms for both stimulus‐locked and response‐locked averaging. This model may be useful in computer simulation studies of LRP scoring methods, and it may open up the possibility of ultimately retrieving trial‐by‐trial information about LRP activity.
