Particularly, the palms of the hands, fingers and foot soles are sensitive recording sites. While sweat glands are present in almost all parts of the body, certain areas respond more strongly to emotional stimulation.

Report the associated skin conductanceĪlthough GSR data might be acquired with arbitrary sampling rates (up to 2000 Hz), very low sampling rates are sufficient. We suggest sampling rates from 1 to 10 Hz, however, keep in mind that higher sampling rates might be necessary if the same device collects GSR and other physiological parameters such as (optical) heart rate, for example. Measure the electrical current between the two electrodesĤ. Place two electrodes on emotionally sensitive body locationsģ.
With GSR, the impact of any emotionally arousing content, product or service can be tested – actual physical objects, videos, images, sounds, odors, food probes and other sensory stimuli as well as thought experiments and mental images.ġ. Exactly this circumstance renders GSR the perfect marker for emotional arousal as it offers undiluted insights into physiological and psychological processes of a person. We simply cannot consciously control the level of skin conductivity. Skin conductivity is solely modulated by autonomic sympathetic activity that drives bodily processes, cognitive and emotional states as well as cognition on an entirely subconscious level. With GSR, you can tap into unconscious behavior that is not under cognitive control. What makes GSR such a valuable biometric signal in assessing emotional behavior? No matter whether we are stressed, nervous, fearful, psyched up, stoked,īaffled, or surprised – whenever we are emotionally aroused, the electrical conductivity of our skin subtly changes. One of the most sensitive measures of emotional arousal is Galvanic Skin Response ( GSR), also referred to as Electrodermal Activity ( EDA) or Skin Conductance ( SC). Our skin reveals a lot of information on how we feel when we are exposed to emotionally loaded images, videos, events, or other kinds of stimuli – both positive (“aww, how cute!”) and negative (“yikes!”).
