This means that GSR measurements are often quicker to record. This means that unlike with EMG, you donвЂ™t need to clean the skin before recording can take place (although it doesnвЂ™t harm to ensure that the signal is as unimpeded as possible). GSR sensitivity is different to EMG recordings. If youвЂ™re also measuring heart rate during the experiment, then place the electrode for heart rate on the ring finger. not the joint), with the electrodes placed on the palm side of the hand. The electrodes should be placed on the proximal part of the finger (i.e. It is also possible to place the electrodes in other locations (such as the shoulders, or even feet). Typically, the electrodes are attached to the index and middle finger. Read on to learn more about the essentials for perfect GSR research. ThatвЂ™s why weвЂ™ve put together our top five recommendations for ensuring high quality GSR data вЂ“ meaning you can have even more confidence in the results. While a fairly straightforward methodology, there are still several critical steps that should be followed to guarantee success with your GSR research. Getting it right however is the important part. Understanding how stimuli (or a stimulus) impacts people can be particularly powerful when combined with other metrics that can determine emotional valence, or attentional processes, as it provides a new dimension to results and findings. This means that it can provide critical information about how someone feels, and also canвЂ™t be consciously controlled, making it an insightful, and unbiased measure of how someone feels. This process is ultimately under the control of the autonomic nervous system. When a stimulus is physiologically or emotionally arousing, the electrical current at the surface of our skin increases. Galvanic skin response (often known as electrodermal activity, or EDA), is a unique way to investigate how our physiological activity can change and fluctuate in response to stimuli. Human behavior research can begin even at the surface of the skin.
