A psychogalvanometer is a device used for measuring changes in the electrical conductance of the skin, which are associated with psychological responses such as excitement, stress or anxiety. Although not commonly used in everyday language, there are a number of synonyms for this word, including skin conductance meter, electrodermograph, and galvanic skin response device. Other related terms include biofeedback sensors, physiological response monitors, and stress response meters. These devices are often used in research settings to study the physiological correlates of emotion, and are also used in therapy to help individuals learn to manage stress and anxiety through biofeedback training.
