The binding problem arises when visual features (colour, orientation), said to be coded in independent brain modules, are to be integrated into unitary percepts. I argue that binding is an ill-posed problem, because those modules are now known to code jointly for multiple features, rendering the feature-binding issue moot. A hierarchical reentrant system explains the emergence of coherent visual objects from primitive features. An initial feed-forward sweep activates many high-level perceptual hypotheses, which descend to lower levels, where they correlate themselves with the ongoing activity. Low correlations are discarded, whereas the hypothesis that yields the highest correlation is confirmed and leads to conscious awareness. In this system, there is no separate binding process that actively assigns features to objects.
当被认为在独立的大脑模块中编码的视觉特征（颜色、方向）要被整合到单一的知觉中时，就会出现绑定问题。我认为绑定是一个不适定的问题，因为现在已经知道这些模块共同编码多个特征，使得特征绑定问题变得无关紧要。一个分层的折返系统解释了从原始特征中出现连贯的视觉对象。初始的前馈扫描激活了许多高级的知觉假设，这些假设向下传递到较低的层次，在那里它们与正在进行的活动相关联。低相关性的假设被丢弃，而产生最高相关性的假设被证实，并导致意识的出现。在这个系统中，没有将特征主动分配给对象的单独绑定过程。
