Adult human subjects (8 male, 8 female undergraduates) with normal vision were required to judge various orientations of the Poggendorff illusion. The transversal and parallel line-segments of the illusion were manipulated to produce the orientations to be judged. Minimum illusion occured when the transversal line-segment was oriented 90 degrees with respect to true vertical or true horizontal. Magnitude of illusion increased as the transversal line-segment deviated from these positions. The findings suggested that there is a stability of horizontal and vertical orientations. In addition, the hypothesis that visual acuity plays a role in the perception of the Poggendorff illusion was proposed.
具有正常视力的成年人类受试者（8名男性和8名女性本科生）被要求判断波根多夫错觉的各种方向。通过操纵错觉的横向和平行线段来产生要判断的方向。当横向线段相对于真垂直或真水平方向成90度时，错觉最小。随着横向线段偏离这些位置，错觉的程度增加。研究结果表明，水平和垂直方向存在稳定性。此外，还提出了视敏度在波根多夫错觉感知中起作用的假设。
