The event-related potential (ERP) technique in cognitive neuroscience allows scientists to observe human brain activity that reflects specific cognitive processes. In An Introduction to the Event-Related Potential Technique, Steve Luck offers the first comprehensive guide to the practicalities of conducting ERP experiments in cognitive neuroscience and related fields, including affective neuroscience and experimental psychopathology. The book can serve as a guide for the classroom or the laboratory and as a reference for researchers who do not conduct ERP studies themselves but need to understand and evaluate ERP experiments in the literature. It summarizes the accumulated body of ERP theory and practice, providing detailed, practical advice about how to design, conduct, and interpret ERP experiments, and presents the theoretical background needed to understand why an experiment is carried out in a particular way. Luck focuses on the most fundamental techniques, describing them as they are used in many of the world's leading ERP laboratories. These techniques reflect a long history of electrophysiological recordings and provide an excellent foundation for more advanced approaches.The book also provides advice on the key topic of how to design ERP experiments so that they will be useful in answering questions of broad scientific interest. This reflects the increasing proportion of ERP research that focuses on these broader questions rather than the "ERPology" of early studies, which concentrated primarily on ERP components and methods. Topics covered include the neural origins of ERPs, signal averaging, artifact rejection and correction, filtering, measurement and analysis, localization, and the practicalities of setting up the lab.
- "Replication is the best statistic. I learned this when I was a graduate student in the Hillyard lab, although no one ever said it aloud. I frequently say it aloud to my students. Replication does not depend on assumptions about normality, sphericity, or independence. Replication is not distorted by "

- "This book is intended as a guidebook for people who wish to use ERPs to answer questions of broad interest in cognitive neuroscience a nd related fields."
- "In most cases, these are techniques that I earned as a graduate student in Steve Hillyard’s laboratory at University of California, San Diego, and they reflect a long history of electrophysiological recordings dating back to Hallowell Davis’ s lab in the 1930s (Davis was the mentor of Bob Galambos, "
- "I believe that the ERP technique is well suited to answering only a small subset of the questions that are important to cognitive neuroscientists. The key, of course, is figuring out which issues this tech-nique best addresses."
- "I take a relatively low-tech approach to ERPs. In the vast majority of cases, I believe that it is better to use a modest number of electrodes and fairly simple data analysis techniques instead of a large array of electrodes and complicated data analysis techniques ."
- "seeming to assume that knowing where a cognitive process happens is the same as knowing how it happens."
- "he showed that one could measure the electrical activity of the human brain by placing an electrode on the scalp, amplifying the signal, and plotting the changes in voltage over time ( Berger, 1929)."
