Skin potential level: age and recording site interactions.
Two experiments comparing the skin potential level (SPL) of young (30 to 47 years), middle-aged (48 to 65 years), and old (66 to 82 years) men during rest and during stimulus presentations using a nonhydrating electrolyte medium demonstrated that there was an ordered relationship between SPL negativity and age with the older men having less negative levels. Age differences in SPL were dependent upon recording site with larger age differences occurring when SPL was recorded from the medial phalanx than when SPL was recorded from the thenar eminence.
