Being able to anticipate upcoming motion is known to potentially mitigate sickness resulting from provocative motion. We investigated whether auditory cues could increase anticipation and subsequently reduce motion sickness. Participants (N = 20) were exposed on a sled on a rail track to two 15-min conditions. Both were identical in terms of motion, being composed of the same repeated 9 m fore-aft displacements, with a semi-random timing of pauses and direction. The auditory cues were either 1) informative on the timing and direction of the upcoming motion, or 2) non-informative. Illness ratings were recorded at 1-min intervals using a 11-point scale. After exposure, average illness ratings were significantly lower for the condition that contained informative auditory cues, as compared to the condition without informative cues. This knowledge, i.e. that auditory signals can improve anticipation to motion, could be of importance in reducing carsickness in domains such as that of autonomous vehicles.
能够预测即将发生的运动被认为可以减轻由刺激性运动引起的不适。我们研究了听觉提示是否可以增加预测并随后减少晕动病。参与者（N=20）在轨道上的雪橇上接受了两种 15 分钟的条件暴露。这两种条件在运动方面完全相同，由相同的重复 9 米前后位移组成，暂停和方向的时间是半随机的。听觉提示要么 1）关于即将发生的运动的时间和方向提供信息，要么 2）不提供信息。使用 11 点量表在 1 分钟间隔记录疾病评分。暴露后，含有信息性听觉提示的条件下的平均疾病评分明显低于没有信息性提示的条件。这一知识，即听觉信号可以改善对运动的预测，对于减少自动驾驶车辆等领域的晕车可能很重要。
