Sweating in the absence of thermal stimulation is one of the cardinal symptoms of motion sickness. But since sweating is closely related to electrodermal activity this may be a potentially useful index of the intensity of motion sickness. In order to evaluate this possibility, the correlations between electrodermal activity and a range of signs and symptoms of motion sickness were examined in four experiments, in which a total of 170 subjects were exposed to a cross-coupled force environment. Although increases in skin conductance did not correlate with specific single indices of motion sickness, correlations with a questionnaire based on several signs and symptoms varied from 0.89 (p less than 0.001) to 0.11 (N.S.). It is concluded that skin conductance potentially offers a valid and very precise measure of motion sickness, but that it is sensitive to extraneous factors only some of which are currently understood.
在无热刺激情况下出汗是晕动病的主要症状之一。但由于出汗与皮肤电活动密切相关，这可能是晕动病强度的一个潜在有用指标。为评估这种可能性，在四项实验中研究了皮肤电活动与一系列晕动病体征和症状之间的相关性，共有170名受试者暴露于交叉耦合力环境中。尽管皮肤电导增加与晕动病的特定单一指标不相关，但与基于多种体征和症状的问卷的相关性从0.89（p小于0.001）到0.11（无显著性差异）不等。结论是皮肤电导可能提供一种有效且非常精确的晕动病测量方法，但它对外部因素敏感，目前仅了解其中一些因素。
