Lie detectors measure electrodermal activity: What is that?

I talk with psychologist Christopher Moyer about electrodermal activity (EDA), also known as galvanic skin response (GSR), which is what lie detectors measure. Topics discussed include: What are spikes in electrodermal activity actually telling us? We talk about its use in lie detectors. We talk about lowerings in skin conductance and what that indicates. We talk about the nature of stress; and how there can be good and bad stress. We talk about poker and gambling, including some gambling-related studies that measured electrodermal activity.
