Normal persons rotated about an Earth-horizontal axis vary in their susceptibility to motion sickness. The purpose of this experiment was to measure, intraindividual differences in susceptibility in 12 subjects when rotated 10 degrees head up and 10 degrees head down as well as in the horizontal position. Subjects assumed the test-position 60 min prior to rotation, thus providing an opportunity for translocation of body fluids. Physiological and psychophysical measurements were conducted throughout the experiment. There were no intraindividual differences in susceptibility to motion sickness in the three positions tested, although there were significant differences in vital capacity, demonstrating the expected fluid shifts. It was concluded that, in the sample of subjects tested, short-term effects of fluid shifts greater than those that would be manifested in zero gravity had no definite effect on motion sickness susceptibility.
正常个体围绕地球水平轴旋转时，其晕动病易感性存在差异。本实验的目的是测量12名受试者在头向上旋转10度、头向下旋转10度以及水平位置旋转时，个体内部的易感性差异。受试者在旋转前60分钟采取测试姿势，从而为体液转移提供机会。在整个实验过程中进行了生理和心理物理学测量。在所测试的三个位置上，个体内部的晕动病易感性没有差异，尽管肺活量存在显著差异，表明出现了预期的体液转移。得出的结论是，在所测试的受试者样本中，大于零重力状态下所表现出的体液转移的短期影响，对晕动病易感性没有明确影响。
