The Use of Brain Electrophysiology Techniques to Study Language: a Basic Guide for the Beginning Consumer of Electrophysiology Information

This article provides a basic background for the professional who is interested in utilizing event-related potential (ERP) approaches to study language processes but has little background in or knowledge about the technique. First, a brief history of the emergence of this technology is presented, followed by definitions, a theoretical overview, and a practical guide to conducting ERP studies. The basis for choice of electrode positions, equipment characteristics (e.g., filter settings), and analyses are also discussed. Finally, examples of language studies that utilize this information in a research study are provided. DENNIS L.
