Abstract
Skin impedance-related measures were obtained at seven pairs of skin locations in 10 male and 10 female college students under resting conditions. The electrode locations were: finger-finger, finger-palm, finger-dorsum, palm-dorsum, palm-forearm, dorsum-forearm, and finger-forearm. An AC constant current recording system with “dry” silver electrodes was used. The current consisted of 60 cps rectangular pulses. It was found that the females showed consistently higher base levels and variability than the males and that electrode position was a highly significant variable. Forearm placements showed consistently higher basal impedance than other locations, while finger-palm placements maximized sex differences. An initial level effect was also demonstrated.
