Skin conductivity (also called electrodermal response or Galvanic Skin Response, GSR) is thought to be an indicator of psychological, emotional or physiological arousal. Measurement of skin conductivity is typically performed by an ohmmeter in which a constant 0.5 V is applied between the electrodes and the resulting current flow is measured by amplifying the voltage across a resistor in series with the skin [5]. 

EDA includes, among others, EDR (electrodermal response), GSR (galvanic skin response), and PGR (psychogalvanic reflex).

Compared to other biosignals taken from the skin, electrodermal activity (EDA) can be r arded as the most convenient measure for workload. Phasic EDA is measured as skin conductance response (SCR) or skin resistance response (SRR). SCR amplitudes may reflect the amount of affective or emotional arousal elicited by a stimulus or situation (see Fig. 1.1). Both amplitude and recovery of an EDR have been demonstrated to be sensitive for certain aspects of central information processing (Boucsein, 1992), and may be used in a manner similar to ERPs as indicators of mental strain. The frequency of spontaneous electrodermal changes (called... 

EEG needed the highest sensitivity, speed was less demanding. ECG needed quick response times. Electrodermal activity galvanometers were not so critical of either speed or sensitivity (Figure 11.1).
