Galvanic Skin Response (GSR)

Galvanic Skin Response (GSR) measures the electrical conductivity of the skin, which changes with moisture levels. When a person experiences emotions like stress, excitement, or anxiety, their sweat glands become more active, increasing skin moisture. This change in conductivity can be detected using sensors and is often used in psychological studies and lie detection tests. GSR provides insights into emotional and physiological arousal, as it reflects how our body reacts to different stimuli and situations without needing verbal expression.
