The perception of the subjective body orientation with respect to a foot reference basis, and the adaptation of mental image rotation have been investigated before, during, and after a 7-d spaceflight. The findings show that the body is tilted forward in darkness and in stabilized vision, which indicates a predominant role of vision in such orientational tasks performed in microgravity. Furthermore, perception of head angular rotation in pitch and roll axes seems to be altered in microgravity, whereas head displacements in yaw are estimated correctly. Subjects' capability to rotate mentally the image of the visual environment increased during the flight. Memorized writing was affected in microgravity, especially concerning the layout of letters corresponding to the vertical direction.
在7天的太空飞行前、飞行期间和飞行后，研究了相对于足部参考基准的主观身体方位感知以及心理图像旋转的适应性。研究结果表明，在黑暗和稳定视觉条件下身体向前倾斜，这表明视觉在微重力环境下执行的此类定向任务中起主要作用。此外，在微重力环境下，俯仰和横滚轴上头部角旋转的感知似乎发生了改变，而偏航方向上的头部位移估计正确。在飞行过程中，受试者在脑海中旋转视觉环境图像的能力有所提高。微重力环境会影响记忆书写，尤其是与垂直方向对应的字母布局。
