Estimated body rotation as a predictor of motion sickness susceptibility.
We rotated 36 blindfolded subjects in yaw between 30 degrees and 135 degrees and asked them to estimate the angular displacement they had experienced. An index of a subject's "receptivity" was obtained by calculating the slope of the line relating perceived to actual displacement; his susceptibility to motion sickness was determined by a questionnaire. The product moment correlation between these two measures was not significant, a result which conflicts with the receptivity hypothesis. It is suggested that "adaptability" rather than "receptivity" may be the more impotant determinant of susceptibility to motion sickness.
