a person's reaction to a stimulus, as measured by electrical monitoring of minute amounts of skin perspiration upon exposure to the stimulus; a physiological testing technique that aims to determine the level of arousal caused by an advertisement. See galvanometer.
A drop in the electrical resistance of the skin, widely used as an index of autonomic reaction.
a change in the electrical properties of the skin in response to stress or anxiety; can be measured either by recording the electrical resistance of the skin or by recording weak currents generated by the body
change in the electrical resistance of the skin; used to measure autonomic reaction.
A measure of physiological arousal determined by the amount of decrease in the skin's resistance to electricity purportedly due to an increase in sweat gland activity.
Changes in electrical conductivity of, or activity in, the skin, detected by a sensitive galvanometer. The reactions are commonly used as an emotional indicator.
Galvanic skin response (GSR), also known as electrodermal response (EDR), psychogalvanic reflex (PGR), or skin conductance response (SCR), is a method of measuring the electrical resistance of the skin. There has been a long history of electrodermal activity research, most of it dealing with spontaneous fluctuations. Most investigators accept the phenomenon without understanding exactly what it means.
