大多数关于视觉诱发运动病（VIMS）的研究要么使用复杂的运动场景，要么仅限于单轴运动。本研究比较了VIMS在单轴和双轴运动期间的情况。12名参与者暴露于（i）振荡滚转运动，（ii）前后轴上的线性运动，以及（iii）螺旋运动，即这两种流动矢量的总和方向。与单独暴露于其组成运动模式相比，在暴露于螺旋运动期间增加的感觉冲突被假设为增加VIMS水平。出乎意料的是，螺旋运动并没有被发现比两个单轴运动模式中的任何一个更具挑衅性，并且这一发现似乎与VIMS由挑衅性刺激的简单求和确定不一致。在螺旋运动条件下，在暴露期间观察到VIMS的非典型降低，之前报告的vection始终降低。据推测，抽象的性质以及不寻常的运动轮廓在螺旋运动条件下可能会呈现刺激越来越“不可能”，并最终被忽视，或“抑制”，作为一个方向线索的中枢神经系统。结果进行了讨论的背景下，VIMS的研究和使用抽象的刺激的潜在局限性的方法学后果。(C)2011爱思唯尔有限公司版权所有。
The majority of studies into visually induced motion sickness (VIMS) either use complex motion scenarios or are limited to single-axis motion. This study compared VIMS during single- and dual-axis motion. Twelve participants were exposed to (i) oscillating roll motion, (ii) linear motion in the fore-and-aft axis, and (iii) spiral motion, i.e. the summed direction of both of these flow vectors. Increased sensory conflict during exposure to spiral motion was hypothesised to increase the level of VIMS compared with exposure to its constituent motion patterns in isolation. Unexpectedly, spiral motion was not found to be more provocative than either of the two single-axis motion patterns, and this finding appears to be inconsistent with VIMS being determined by simple summation of the provocative stimuli. In the spiral motion condition, an atypical decrease in VIMS was observed during exposure, which was consistently preceded by a reduction in reported vection. It was hypothesised that the abstract nature as well as the unusual motion profile in the spiral motion condition may have rendered the stimulus increasingly 'improbable' and ultimately being disregarded, or 'quarantined', as an orientation cue by the central nervous system. The results are discussed in the context of methodological consequences for VIMS research and potential limitations of the use of abstract stimuli. (C) 2011 Elsevier B.V. All rights reserved.
