Abstract
This paper reviews the use of event-related brain potentials (ERPs) in clinical neuropsychology research. First, a short overview of basic methodological issues is given. The main part reviews studies that explored the information processing stages that are reflected by the ERP-components. Here, the focus is on components that have been used in clinical neuropsychology research (early, attention-sensitive components; mismatch-negativity (MMN); P300; N400; lateralized readiness potential; CNV; readiness potential; error-related negativity). For each component, examples of research relevant for clinical neuropsychology are given
ERPs are a very powerful tool in exploring information processing deficits in patients with brain damage, and developmental or degenerative neurological conditions. Their main contribution is the revelation of the time-course of information processing and of the subprocesses involved in complex cognitive activities. Thus, ERPs can provide new insights into the time-course of information processing deficits in brain damaged patients.
