预测编码的框架为许多感知现象提供了简约的解释。根据这一框架，对外部世界的感知是通过将传入的感觉信息与基于先前经验和背景的内部预测模型进行比较来创建的。然而，尚不清楚被预测的感知是否需要进入有意识的意识才能使内部预测模型有效。在这里，我们使用了一个明显的运动范式来表明，尽管对预测的感知和对预测的感知的意识可能是一致的，但可以观察到分离。当感觉信息为内部预测模型提供可靠的输入时，被预测的感知不必为了成功的预测而被有意识地感知。然而，当感觉输入模棱两可时，有意识的意识有助于预测生效。
The framework of predictive coding offers a parsimonious explanation for many perceptual phenomena. According to this framework, perception of the outer world is created by the comparison of incoming sensory information with an internal predictive model based on previous experience and context. However, it is unclear whether the predicted percept needs to enter conscious awareness for the internal predictive model to be effective. Here we used an apparent motion paradigm to show that while prediction and conscious awareness of a predicted percept may coincide, a dissociation can be observed. When sensory information provides reliable input for the internal predictive model, the predicted percept does not have to be consciously perceived for successful prediction. However, when sensory input is ambiguous, conscious awareness helps the prediction to take effect.
