对直线水平运动感觉的基本特征进行了研究。目标直线运动是通过移动小车的方式来实现的。视觉诱导的线性运动知觉(线性向量)是通过将运动图像投影到视野边缘而获得的。已经测量了出现线性弯曲的图像速度和亮度阈值，并在视觉系统检测图像运动(没有自我运动的感觉)的范围内。发病潜伏期约为1秒，并已显示出短期适应。由频率分析判断的视觉分析器的动态范围低于前庭分析器。在视觉线索与前庭和其他本体感觉线索相矛盾的情况下，在线性视觉的情况下，视觉的支配地位支持视觉在自我运动知觉中的基本作用，尽管不是独立的。
SummaryThe basic characteristics of the sensation of linear horizontal motion have been studied. Objective linear motion was induced by means of a moving cart. Visually induced linear motion perception (linearvection) was obtained by projection of moving images at the periphery of the visual field. Image velocity and luminance thresholds for the appearance of linearvection have been measured and are in the range of those for image motion detection (without sensation of self motion) by the visual system. Latencies of onset are around 1 sec and short term adaptation has been shown. The dynamic range of the visual analyser as judged by frequency analysis is lower than for the vestibular analyser. Conflicting situations in which visual cues contradict vestibular and other proprioceptive cues show, in the case of linearvection a dominance of vision which supports the idea of an essential although not independent role of vision in self motion perception.
