Zusammenfassung:
In 2 experiments, the Muller-Lyer illusion (F. C. Muller-Lyer, 1889; N = 16) and the parallel-lines illusion (W. Wundt, 1898; N = 26) clearly
affected maximum preshape aperture in grasping (both ps < .001). The grasping effects were similar but not perfectly equal to the perceptual effects. Control
experiments show that these differences can be attributed to problems in matching the perceptual task and the grasping task. A model is described stating the
assumptions that are needed to compare the grasping effects and the perceptual effects of visual illusions. Further studies on the relationship between
perception and grasping are reviewed. These studies provide no clear evidence for a dissociation between perception and grasping and therefore do not
support the action versus perception hypothesis (A. D. Milner M. A. Goodale, 1995).
