有许多关于两个视觉系统的争论（whatvs。如何或感知vs.这是古德尔和他的同事们提出的一个假说。许多研究人员提供了各种支持或反对这一假设的证据。例如，Agliotiet等人进行的一项研究为使用艾宾浩斯错觉的双视觉系统理论提供了很好的证据，但一些使用其他视觉错觉的研究人员未能找到一致的结果。因此，我们使用冲突或干扰的知觉任务来检验这一假设。如果知觉中的冲突或干扰只影响知觉的加工，而不影响动作的加工，我们就可以推断这两个视觉系统是分离的，反之亦然。在本研究中，我们进行了两个实验，采用Stroop，加纳和SNARC范式，并使用可抓取的三维阿拉伯数字。我们的目的是发现知觉冲突或干扰所产生的效果是否会影响被试的抓握和指向。结果表明，Stroop与数字顺序（升序或降序，或SNARC）的交互作用显著，SNARC效应显著影响动作，而Stroop和Garner干扰的主效应不显著。结果表明，知觉冲突在一定程度上影响动作加工。结果没有提供两个独立视觉系统的证据。
There have been many debates of the two-visual-systems (whatvs. how or perceptionvs. action) hypothesis that was proposed by Goodale and his colleagues. Many researchers have provided a variety of evidence for or against the hypothesis. For instance, a study performed by Agliotiet al. offered good evidence for the two-visual-systems theory using the Ebbinghaus illusion, but some researchers who used other visual illusions failed to find consistent results. Therefore, we used a perceptual task of conflict or interference to test this hypothesis. If the conflict or interference in perception had an influence on the processing of perception alone and did not affect the processing of action, we could infer that the two visual systems are separated, and vice versa. In the current study, we carried out two experiments which employed the Stroop, Garner and SNARC paradigms and used graspable 3-D Arabic numerals. We aimed to find if the effects resulting from perceptual conflicts or interferences would affect participants’ grasping and pointing. The results showed that the interaction between Stroop and numeral order (ascending or descending, or SNARC) was significant, and the SNARC effect significantly affected action, but the main effects of Stroop and Garner interference were not significant. The results indicated that, to some degree, perceptual conflict affects action processing. The results did not provide evidence for two separate visual systems.
