Visually-induced self-motion sensation and postural reflexes were first explored in microgravity on the Spacelab 1 mission where four subjects demonstrated that visual orientation effects were stronger in microgravity than preflight. Extended testing of two more subjects during the Spacelab D-1 orbital flight confirmed this finding. The development of visual substitution for inappropriate graviceptor information occurs over the first day or two in microgravity. Additional instrumentation to measure postural reactions failed to produce a more reliable indicator of visual effects than subjective orientation. Localized tactile cues applied to the feet changed the qualitative nature of vection and reduced its subjective strength.
视觉诱发的自我运动感觉和姿势反射最初是在“太空实验室1号”任务的微重力环境中进行探索的，在该任务中，四名受试者证明视觉定向效应在微重力环境中比飞行前更强。在“太空实验室D-1号”轨道飞行期间对另外两名受试者进行的进一步测试证实了这一发现。视觉替代不适当重力感受器信息的发展在微重力环境中的头一两天内就会出现。用于测量姿势反应的额外仪器未能产生比主观定向更可靠的视觉效应指标。施加在脚部的局部触觉线索改变了视动的性质，并降低了其主观强度。
