Galvanic skin response

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].

Figure 10.9 Measured 88 Hz admittance galvanic skin response activity on palmar skin sites. A deep breath at approximately 20 s on the time scale triggered the response.

In connection with road traffic, with its special condition of self-determination of the rate of work, studies by Taylor [6-40] and Wilde [6-41] have indicated that there is an adequate awareness of the risk content in particular situations. Both authors carried out field experiments which showed that drivers regulate their behavior within the MME-system so that the risk they experience fluctuates only between narrow limits. Thus Taylor reported that drivers tend to increase the speed of the vehicle in situations in which low risk is perceived, and to reduce speed if the perceived risk increases again. The perceived risk was determined in these experiments using the psycho-physiological measure of the galvanic skin response. In a similar experiment Galton and Wilde [6-42] showed that the subjective risk was determined on the basis of a verbally formulated risk scale. The test route consisted of 11 sections with heterogeneous traffic...
