Racial Differences in Skin Resistance
Johnson, Laverne C.; Corah, Norman L.
Science, Volume 139, Issue 3556, pp. 766-767
In two laboratories utilizing different age subjects and recording techniques, Negro subjects had higher skin resistance than a comparable white population. There was no difference in other autonomic variables or autonomic reactivity. Reasons for this racial difference may offer a better physiological explanation for galvanic skin resistance.
