Abstract How does the eye guide the hand in an ever-changing world? The perception-action model posits that visually-guided actions rely on object size estimates that are computed from an egocentric perspective independently of the visual context. Accordingly, adjusting grip aperture to object size should be resistant to illusions emerging from the contrast between a target and surrounding elements. However, experimental studies gave discrepant results that have remained difficult to explain so ...

The theory of two visual systems assumes that visual perception relies on a ventral pathway extending from the striate cortex to the inferior temporal cortex, whereas visually-guided action relies on a dorsal pathway extending from the striate cortex to the superior parietal cortex. The finding that size-contrast illusions deceive perception but not action has long been taken as supporting the independence of these two pathways. For example, the Ebbinghaus illusion shows that the size of a centr...
