背景线索，如线性视角和相对大小，可以对物体的感知产生强大的影响。这一事实可以通过这些线索引起的错觉效果（例如，庞佐铁路轨道和铁钦纳圆圈错觉）来证明。然而，最近的几项研究报道，基于这些线索的视觉错觉对用于指导手部动作的视觉运动机制几乎没有或根本没有影响。此外，这类证据被引用来支持视觉感知和视觉控制行为之间的区别。在本研究中，作者研究了Ponzo视错觉对手动作控制的影响，特别是在抓握运动中握力和握力孔径的缩放。结果表明：握持力尺度受Ponzo视错觉影响显著，而握持孔径尺度不受Ponzo视错觉影响。
Contextual cues such as linear perspective and relative size can exert a powerful effect on the perception of objects. This fact is demonstrated by the illusory effects that can be induced by such cues (e.g., the Ponzo railway track and Titchener circles illusions). Several recent studies have reported, however, that visual illusions based on such cues have little or no influence on the visuomotor mechanisms used to guide hand action. Furthermore, evidence of this sort has been cited in support of a distinction between visual perception and the visual control of action. In the current study, the authors investigated the effect of the Ponzo visual illusion on the control of hand action, specifically, the scaling of grip force and grip aperture during prehension movements. The results demonstrate that grip force scaling is significantly influenced by the Ponzo visual illusion, whereas the scaling of grip aperture is unaffected by the illusion.
