Question

Quizplus · Accepted Answer

A polygraph measures changes in skin conductance, also known as galvanic skin response, which reflects changes in sweat gland activity and can be an indicator of emotional arousal or stress. Although changes in mood, body temperature, and electrical activity in the brain may occur during a polygraph test, skin conductance is the primary physiological response measured.
