The finding that the Ebbinghaus/Titchener illusion deceives perception but not grasping is usually seen as strong evidence for Goodale and Milner's (1992) notion of two parallel visual systems, one being conscious and deceived by the illusion (vision-for-perception) and the other being unconscious and not deceived (vision-for-action). However, this finding is controversial and led to studies with seemingly contradictory results. We argue that these results are not as contradictory as it might seem. Instead, studies consistently show similar effects of the illusion on grasping. The perceptual effects are strongly dependent on the specific perceptual measure employed. If, however, some methodological precautions are used, then these diverse perceptual results can be reconciled and point to a single internal size estimate that is used for perception and for grasping. This suggests that the Ebbinghaus illusion deceives a common representation of object size that is used by perception and action.

掌握视觉幻觉:一致的数据,没有分离。

Ebbinghaus / Titchener幻觉欺骗了感知但没有把握的发现通常被认为是Goodale和Milner(1992)的两个平行视觉系统概念的有力证据,其中一个是被幻觉(视力感知)感知并被其欺骗的,其他则是潜意识中的,未被欺骗的(行动视觉)。然而,这一发现是有争议的,并导致研究结果看似矛盾。我们认为这些结果并不像看起来那样矛盾。取而代之的是,研究始终显示出错觉对抓握的类似影响。感知效果在很大程度上取决于所采用的特定感知手段。但是,如果使用了一些方法上的预防措施,然后可以调和这些不同的感知结果,并指向用于感知和把握的单个内部大小估计。这表明艾宾豪斯幻觉欺骗了感知和行动所使用的物体大小的通用表示。
