摘要

During sinusoidal whole-body oscillation, three tasks, two visual and one auditory, were presented, respectively, to three groups of ten subjects each. Before and after this conditioning period, nystagmus recorded while subjects were engaged in visual compensatory tracking revealed a diminution in slow phase velocity of nystagmus of 59 percent for one visual group and 33 percent for the other. There was a 23 percent decrease in the group with the auditory task. Pre- and post-nystagmus recorded in the dark before and after conditioning showed an approximately equal reduction among the groups of about 22 percent. A reduction in visual compensatory tracking errors of approximately 21 percent was found, also with no apparent difference between groups. Subjective reports, however, indicated that the visual groups had less blurring after the conditioning even though this difference between groups was not reflected in the performance task.
