人们早就知道，围绕着一个固定的、蒙上眼睛的观察者旋转的声场可以在20- 60%的参与者中引起自我运动错觉（“圆形向量”）。在这里，我们调查是否听觉循环向量可能取决于参与者是否感觉到并知道实际的运动是可能的或不可能的。虽然听觉向量研究的参与者经常坐在可移动的座位上，以暂停对自我运动的怀疑，但从未调查过这是否真的促进了向量。为此，参与者坐在吊床椅子上，他们的脚要么在坚实的地面上（“运动不可能”的条件），要么暂停（“运动可能”的条件），同时听取两个声源以60°/s同步旋转的个性化双耳录音。此外，在一半的试验中施加了几乎不可察觉的振动。8/16例受试者诱发出听觉循环波。对于那些，增加振动增强矢量在所有相关的措施。不接触坚实的地面增加了自我运动的强度和在物理房间中实际旋转的感觉。然而，感染起始潜伏期和引起感染的试验百分比仅受到轻微的显著影响（p<0.10）。总之，这表明当一个人感觉到并知道物理运动实际上是可能的（即使参与者总是保持静止）时，听觉自我运动错觉可能会更强。而且，增加震动和悬空都有好处。这些结果具有重要的意义，无论是我们的理论理解的自我运动的感知和自我运动模拟，振动和认知/感知框架，实际的运动是可能的，通常可以提供在最小的成本和努力的应用领域。
It has long been known that sound fields rotating around a stationary, blindfolded observer can elicit self-motion illusions ("circular vection") in 20--60% of participants. Here, we investigated whether auditory circular vection might depend on whether participants sense and know that actual motion is possible or impossible. Although participants in auditory vection studies are often seated on moveable seats to suspend the disbelief of self-motion, it has never been investigated whether this does, in fact, facilitate vection. To this end, participants were seated on a hammock chair with their feet either on solid ground ("movement impossible" condition) or suspended ("movement possible" condition) while listening to individualized binaural recordings of two sound sources rotating synchronously at 60°/s. In addition, hardly noticeable vibrations were applied in half of the trials. Auditory circular vection was elicited in 8/16 participants. For those, adding vibrations enhanced vection in all dependent measures. Not touching solid ground increased the intensity of self-motion and the feeling of actually rotating in the physical room. Vection onset latency and the percentage of trials where vection was elicited were only marginally significantly (p<.10) affected, though. Together, this suggests that auditory self-motion illusions can be stronger when one senses and knows that physical motion might, in fact, be possible (even though participants always remained stationary). Furthermore, there was a benefit both of adding vibrations and having one's feet suspended. These results have important implications both for our theoretical understanding of self-motion perception and for the applied field of self-motion simulations, where both vibrations and the cognitive/perceptual framework that actual motion is possible can typically be provided at minimal cost and effort.
