Oppel-Kundt错觉存在于对填充区与空区的长度的高估中。两个实验探讨了它与水平-垂直错觉的关系，其中包括高估垂直与水平范围的长度，以及倾斜效应，其中包括倾斜相对于水平或垂直方向的刺激的辨别灵敏度较差。在实验1中，将Kundt（1863）的原始刺激以45度的步长围绕360度旋转整圈。对于实验2，刺激的一部分保持在水平或垂直方向，而另一部分倾斜45度或90度。在水平方向的刺激，Oppel-Kundt错觉是在其最大值。当垂直部分为空时，L型图形的错觉强烈减弱，但当这部分被填充时，这种错觉并没有增强，这表明水平-垂直错觉只作用于非纹理范围。没有间接影响。
The Oppel-Kundt illusion consists in the overestimation of the length of filled versus empty extents. Two experiments explored its relation to the horizontal-vertical illusion, which consists in the overestimation of the length of vertical versus horizontal extents, and to the oblique effect, which consists in poorer discriminative sensitivity for obliquely as opposed to horizontally or vertically oriented stimuli. For Experiment 1, Kundt's (1863) original stimulus was rotated in steps of 45 degrees full circle around 360 degrees. For Experiment 2, one part of the stimulus remained at a horizontal or vertical orientation, whereas the other part was tilted 45 degrees or 90 degrees. The Oppel-Kundt illusion was at its maximum at a horizontal orientation of the stimulus. The illusion was strongly attenuated with L-type figures when the vertical part was empty, but not enhanced when this part was filled, suggesting that the horizontal-vertical illusion only acts on nontextured extents. There was no oblique effect.
