Few studies have evaluated the influence of idiosyncrasies that may influence the judgment of space-time orientation after passive motion. We designed a study to assess the influence of anxiety/depression (which may distort time perception), motion sickness susceptibility (which has been related to vestibular function, disorientation, and to the velocity storage mechanism), and personal habits on the ability to update orientation, after passive rotations in the horizontal plane. Eighty-one healthy adults (22–64 years old) accepted to participate. After they completed an in-house general health/habits questionnaire, the short Motion Sickness Susceptibility Questionnaire, the Hospital Anxiety and Depression Scale (HADS), the Pittsburgh Sleep Quality Index, and the short International Physical Activity Questionnaire, they were exposed to 10 manually driven whole-body rotations (45°, 90°, or 135°), in a square room, with distinctive features on the walls, while seated in the normal upright position, unrestrained, with noise-attenuating headphones and blindfolded. After each rotation, they were asked to report which wall or corner they were facing. To calculate the error of estimation of orientation, the perceived rotation was subtracted from the actual rotation. Multivariate analysis showed that the estimation error of the first rotation was strongly related to the results of the orientation test. The magnitude and the frequency of estimation errors of orientation were independently related to HADS anxiety sub-score and to adult motion sickness susceptibility, with no influence of age, but a contribution from the interaction of the use of spectacles, the quality of sleep and sex. The results suggest that idiosyncrasies may contribute to the space-time estimation of passive self-motion, with influence from emotional traits, adult motion sickness susceptibility, experience, and possibly sleep quality.

很少有研究评估可能影响被动运动后时空定向判断的特质的影响。我们设计了一项研究来评估焦虑/抑郁（可能会扭曲时间感知）、晕车易感性（与前庭功能、定向障碍和速度存储机制有关）和个人习惯对更新能力的影响方向，在水平面被动旋转后。81 名健康成年人（22-64 岁）接受参与。在他们完成内部一般健康/习惯问卷、简短的晕车易感性问卷、医院焦虑和抑郁量表 (HADS)、匹兹堡睡眠质量指数和简短的国际体育活动问卷后，他们在一个方形房间内进行 10 次手动驱动的全身旋转（45°、90° 或 135°），墙壁上具有鲜明的特征，同时以正常的直立姿势坐着，不受约束，戴着降噪耳机和蒙住眼睛。每次轮换后，他们被要求报告他们面对的墙壁或角落。为了计算方向估计的误差，从实际旋转中减去感知旋转。多变量分析表明，第一次旋转的估计误差与定向测试的结果密切相关。方向估计误差的幅度和频率与 HADS 焦虑分项和成人晕动病易感性独立相关，不受年龄的影响，但与眼镜使用的相互作用有关，睡眠质量和性生活。结果表明，特质可能有助于被动自我运动的时空估计，受情绪特征、成人晕动病易感性、经验和可能的睡眠质量的影响。
