该实验研究了无光流行走对随后的矢量感应和强度的影响。两组参与者在受到矢量诱导刺激之前步行 5 分钟（佩戴 Ganzfeld 护目镜或视力正常）。然后，我们测量了由光流径向扩展模式引起的矢量的起始潜伏期和强度。结果表明，没有光流的行走会暂时产生较晚的矢量起始并降低矢量强度。我们提出，没有光流的行走会触发感觉重新调整，从而降低光流诱导自我运动感知的能力。
This experiment investigated the effect of walking without optic flow on subsequent vection induction and strength. Two groups of participants walked for 5 min (either wearing Ganzfeld goggles or with normal vision) prior to exposure to a vection-inducing stimulus. We then measured the onset latency and strength of vection induced by a radially expanding pattern of optic flow. The results showed that walking without optic flow transiently yielded later vection onsets and reduced vection strength. We propose that walking without optic flow triggered a sensory readjustment, which reduced the ability of optic flow to induce self-motion perception.
