Humans can rapidly extract object and category information from an image despite surprising limitations in detecting changes to the individual parts of that image. In this article we provide evidence that the construction of a perceptual whole, or Gestalt, reduces awareness of changes to the parts of this object. This result suggests that the rapid extraction of a perceptual Gestalt, and the inaccessibility of the parts that make up that Gestalt, may in fact reflect two sides of the same coin whereby human vision provides only the most useful level of abstraction to conscious awareness.
尽管人类在检测图像中各个部分的变化方面存在惊人的局限性，但他们能够迅速从图像中提取物体和类别信息。在本文中，我们提供的证据表明，对整体或完形的构建降低了对该物体各部分变化的感知。这一结果表明，对感知完形的快速提取以及构成该完形的各部分的不可知性，实际上可能反映了同一枚硬币的两面，即人类视觉仅向意识知觉提供最有用的抽象层次。
