This article is in desperate need of sources for all the points it advances. Since it is linked to the Scientology as it is this principle they use for their E-meters, all of this article needs to be sourced.


According to McGraw-Hill Encyclopedia of Science & Technology Online, "Electrodermal response (EDR) has replaced galvanic skin response as the collective term."[1] From what I've seen in research articles that use EDR testing, this is true (for instance, if you do an article database search for psychopathy+electrodermal you'll get far more hits than for psychopathy+galvanic). With this in mind, wouldn't it make more sense to do the suggested merge the other way around? In other words, merge the EDR article into this galvanic skin response article, then move the whole thing to "Electrodermal response" with a redirect?

Okay, so... unless someone objects in the next few days, I'll go ahead and do that. --Zeligf 04:59, 10 March 2006 (UTC)

Early history?[edit]

It seems that the first published documentation of electrodermal activity (or EDA, GSR, EDR, SCR or whatever) was in 1890 and was coined the Tarchanoff Response (after the researcher).

Just thought I'd stick this in here to nudge expansion of the topic. Maybe I'll do it myself when I've finished my vast university workload (mainly self induced...) but until then editing Wikipedia counts as procrastination.

There is a large body of research around this area (much available online) and the wiki entry is wanting for detail. If anyone has an 'Athens' account or wants to learn more through google scholar there should be ample material complete with proper referencing... 16:30, 13 August 2007 (UTC)Toby

New title[edit]

This article should be titled electrodermal activity or something more general like that, because it describes more than simply the GSR. As the name implies, response (in GSR, EDR or SCR) refers to a single response (one peak) inside the electrodermal activity signal. Skin conductance level (SCL) is electrodermal activity but not a response (cf. ERP vs. longer measurements in EEG). However, it is late and I can't think how this is done properly right now.

I propose we use the title skin conductance, because it most precisely defines the measurement. In my experience and in searches of the literature, it is the more widely used term. While I understand "electrodermal activity" is also widely used, I do not like it because the skin does not generate anything electrical (or rather, the article content is not related to anything electrically generated by the skin). This article is about how much the skin is sweating, which can be measured by conductivity (impedance). Galvanic refers to steel coated with zinc, so is definitely outdated. I also prefer skin conductance without "level" or "response" because the two terms are related and both widely used in the literature. I wish the predominant term directly addressed skin moisture, but alas, it does not. -kslays (talkcontribs) 16:35, 26 February 2010 (UTC)
Ah, no, the article is not about "sweat," which was only a hypothesis for the cause of EDA, and not the currently accepted hypothesis either. Much more research has been done since the "sweat" hypothesis, as shown by all the authorities quoted. In 1889, Ivane Tarkhnishvili observed self-generated potentials on the skin, not conductance of externally applied current. And Tarkhnishvili was apparently the one who originated the term "psychogalvanic," according to this source[1] on his page. A sensitive ohmmeter applied to the skin will show all manner of variation, without discriminating between changes in potential and changes in conductance. Some of the journal sources state the best place to observe EDA is the palms and the soles. Slade Farney (talk) 04:47, 28 April 2015 (UTC)
