Introduces the principles and practice of psychophysiology. Psychophysiology is an interdisciplinary science that uses biological measures, typically those recorded via sensors on or imaging of the body, where the scientific goal is to understand psychological processes, psychological principles, or the effects of psychological interventions. Combines learning about the basic methods of psychophysiology (with an emphasis on peripheral psychophysiology), the principles underlying these methods, scientific evidence, and the current scientific questions that psychophysiological methods are used to answer.
