title: Estimated body rotation as a predictor of motion sickness susceptibility.
abstract: 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.
