本文研究了正常人在被动前庭刺激(全身在空间中侧移)、本体感觉刺激(双脚相对于躯干)及其组合闭眼时的空间运动知觉。刺激为正弦波，+/-10 cm，频率范围为0.025-0.4赫兹。由于相当高的检测阈值，前庭自我运动知觉在低频时越来越被低估。低频本体感觉刺激引起一种小的自动错觉。在身体相对于静止的脚(前庭-本体感觉的结合)的平移过程中，感知到的自我运动的大小在频率上是恒定的，其阈值很低，似乎只由本体感觉决定。然而，这一结果可以用前庭-本体感觉的相互作用来解释，类似于以前关于旋转刺激的发现。
Sell-motion perception in space was studied in normal human subjects during passive vestibular stimulation (lateral translation of whole body in space), proprioceptive stimulation (of feet relative to trunk) and combinations thereof with the eyes closed. Stimulation was sinusoidal, +/-10 cm, over a frequency range of 0.025-0.4 Hz. Vestibular self-motion perception became increasingly underestimated at low frequency, due to a rather high detection threshold. Proprioceptive stimulation at low frequency elicited a small self-motion illusion. During body translation relative to the stationary feet (vestibular-proprioceptive combination) the magnitude of perceived self-motion was constant across frequency and its threshold was low, as if determined by proprioception alone. Nevertheless, the results can be interpreted in terms of a vestibular-proprioceptive interaction, in analogy to previous findings for rotational stimuli.
