If you ever had any questions concerning the Electro Dermal Activity (EDA) aka the Galvanic Skin Response (GSR) this article will have the answer. It is an extensive review concerning the major contributor to polygraph test results, as, in the authors’ words: “a number of studies have shown that EDA data has a stronger correlation with the external criterion compared to other data recorded during comparison question testing”.
