Skin conductance, galvanic skin response, electrodermal activity: What is the phenomenon that describes how electricity is conducted across human skin? In this video, we’ll take a quick look at the history and the mechanism of electrodermal activity, how it’s used, and whether we can trust the results. If you want to know how a lie detector works, how a love tester works, or how an e-meter works, then sit down for a quick primer!
