Galvanic Skin Response (GSR) Kit

  • RM150.00

  • Product Code: GSR
  • Availability: In Stock

Galvanic skin response (GSR), also referred to as skin conductance response (SCR) or electrodermal activity (EDA), is the property that momentarily makes our skin a better conductor of electricity when we are physiologically aroused.

When we are aroused, a number of body processes get activated – for instance, our heart beats faster and pulse rise. We also sweat more, and as we sweat, our skin conductance increases.

So, GSR is essentially triggered by sweating, and is measured in micro-Siemens (µS) or micro-Mho (µM). (It is actually a more complex phenomenon, particularly in light of recent research findings. Practitioner’s, however, need not get into the finer details).

Arousal is one of the two main dimensions of emotion, the other being valence. GSR can capture emotional arousal, or the level of stimulation, and this makes it a strong predictor of attention and memory. It does not reveal emotional valence, i.e. it is unable to detect whether we are feeling good (positive) or whether we are feeling bad (negative). In this respect, GSR and facial coding are complementary. Facial coding captures the valence of emotion, but cannot gauge the associated arousal.

Since sweat secretion cannot be consciously controlled, GSR is able to track autonomic arousals. This is what makes it a non-deceptive indicator of our emotions. It also explains its use along with other technologies, in lie-detectors.

The other prime advantage is that GSR is relatively inexpensive and easy-to-measure, requiring fairly simple devices.
