The galvanic skin response or GSR allows us to understand and measure the physiological properties of the skin. The skin is a very large organ and one that can have a lot of properties. That is why this is one of the best options to better understand your status.
By means of this, all the changes that occur during the moment of activation can be measured. This may even be able to gauge if the person is telling a lie. Although it may seem difficult, it is not and it is because, at the moment of lying, the skin is physiologically activated. Even if it is not noticeable, it responds to the anxiety or stress of the moment.
What can be detected with this?
As we already mentioned, the skin is an organ that reacts in different ways. This is the “interface” that links the outside with the inside, so it is normal that it can offer a large amount of information.
Among the functions that the skin can carry out, we have the following:
Thermoregulation: The skin manages body temperature and regulates it through peripheral blood circulation. That is why this is responsible for measuring this property of the skin.
Immune System: The skin is responsible for separating the interior of the body from the exterior. There are many things to which the skin is exposed and this affects it in many ways. the RSG is capable of detecting these things.
Detection and perception: The skin also has many nerve endings that allow it to feel what is outside.
All these elements are part of the behavior of the skin and, through an electrothermal response, the RSG is able to detect variations.
How is galvanic response measured?
Measuring galvanic skin response is a fairly simple process that is carried out. For this, it is necessary to have a specialized team that is responsible for measuring and recording the changes in the conductivity of the skin.
This entire process is carried out in three simple steps that are summarized as follows:
- The first thing is to place the specialized equipment, which has two sensors or electrodes. These are placed on two fingers of the hands and this is because this is where there are more sweat glands.
- The equipment is responsible for emitting a very small electrical charge through the electrodes. In this way, it is possible to measure the conductivity of the body and the degree of moisture in the skin.
- The data goes to specialized software that is responsible for interpreting the voltage received by the electrodes. Then, the reading and analysis of the results is carried out.
In order to carry out this test, it is necessary to have a laboratory environment and under special conditions to guarantee its reliability. Although it may seem like a complex process, the truth is that it is very simple.
Even today there are a large number of devices that are responsible for doing this. And this is because there are a large number of people who are studying and who have been interested in this.
In the world of neuromarketing, this practice has become quite common, which is why it has aroused the interest of many companies. Although this is not an exact science and has some limitations, the truth is that the information it provides can be very valuable for some brands and people.
