(from the Association for Applied Psychophysiology and Biofeedback) Psychophysiology is the field that studies the relationship between mental activity and physical functions — in other words, investigates the mind-body connection in a scientific way. Psychophysiologists are interested in how mental characteristics affect the body, how we experience information from our body, exactly what changes happen when people experience particular emotions, etc. Applied psychophysiology is the discipline that uses this information for practical purposes. For example, psychophysiologists do research to find how to teach people better ways to learn to control body functions that may be causing health problems. They also study ways to predict and prevent stress-related health problems of individuals. Biofeedback is one method of self-regulation that is constantly studied and refined by psychophysiologists.
