GSR Biofeedback

What Is GSR?

GSR stands for galvanic skin response. It is a relatively inexpensive and simple method of monitoring that is often used in home biofeedback devices. Unlike the more advanced neurofeedback, which measures brain activity directly, GSR measures the mind indirectly through the physiological responses of the body.

GSR is also somtimes known as "Electrodermal Response" (EDR)

As the name suggests, GSR biofeedback devices work by analysing the skin. The device measures the electrical resistance of the skin through two electrodes and compares this value to a previously taken baseline reading. This resistance is affected by autonomic responses such as sweat and can therefore be used as a measure of anxiety, stress or general emotional arousal. A monitor such as a visual display or varying tone allows the user to monitor their state and attempt to adjust it accordingly.

GSR biofeedback is sometimes used in the treatment of stress and similar conditions by qualified professionals For such professional work it is sometimes combined with other more advanced forms of biofeedback measurement.

Always consult a doctor concerning any medical issues.

History

The technique has been around for over a century. The first known user was Tarchinoff who discovered skin resistance in 1888. In 1890 he presented the first paper on the subject of the "psycho-galvanometer". This was the ancestor of modern GSR biofeedback technology.

In 1906 Carl Jung discussed a technique for using GSR to measure the subject's responses to various emotionally laden words.

Home GSR Machines

In the home, GSR is used in many of the personal biofeedback machines on the market designed to help you in training your mind. The large, cumbersome psychogalvanometer of Tarchinoff has given way to affordable personal units, some even hand held.

Home GSR equpiment normally uses sound and/or light cues to tell you about the response levels being measured through the skin. Perhaps the simplest is the audio feedback: a single rising or falling tone.

Today can buy everything from "mind machines" which are intended to help improve relaxation, concentration, etc. to biofeedback based mental games!
