感受器提示的修改可能会影响视觉和姿势知觉的准确性。在没有视觉提示的情况下，处于侧倾角度的受试者被要求返回到垂直姿势。通过引入厚厚的软垫座椅，美感的提示被修改了。在硬座和软座下，恒定误差没有显著差异；软座的可变性有显著差异。不确定度(U[度])被定义为中间75%的判断。硬座U的平均值在3.4度到7.4度之间，软座U的平均值在6.4度到10.3度之间，具体取决于使用的方法。坐在直立位置的被试对视觉垂直和视觉水平的平均判断分别为0.3和0.4；当处于倾斜位置时，对视觉水平的判断错误有显著增加的趋势。
Modification of receptor cues may be expected to influence the accuracy of visual and postural perception. Subjects placed at angles of lateral tilt were required to return themselves to the postural vertical in the absence of visual cues. Somesthetic cues were modified by the introduction of a thickly padded soft seat. Constant errors did not differ significantly under hard and soft seat; there was a significant difference in variability in favor of soft seat. The arc of uncertainty (U[degree]) was defined as the middle 75% of judgments. Under hard seat, the mean value of U varied from 3.4[degree] to 7.4[degree]; under soft seat U varied from 6.4[degree] to 10.3[degree], depending upon the method. The mean judgments of the visual vertical and the visual horizontal made by subjects seated in the upright position were 0.3 and 0.4, respectively; when placed in positions of tilt there was a significant tendency towards increase in the errors of judgment of the visual horizontal.
