The measurement of electrodermal activity is arguably the most commonly used method for capturing physiological correlates of psychological processes. This monograph presents a comprehensive overview for the first time: it integrates the anatomical, physiological, physical, and psychological foundations, describes the methodology, and outlines the use of electrodermal measurement techniques in the key application areas of the involved disciplines. The book is considered a standard work. It provides information on central and peripheral mechanisms of electrodermal activity as well as corresponding model concepts. It conveys the fundamentals of measurement techniques, the methods for capturing, recording, and processing electrodermal phenomena. The methodological section includes concrete instructions.
