Multisensory integration involves a host of different cognitive processes, occurring at different stages of sensory processing. Here I argue that, despite recent insights suggesting that multisensory interactions can occur at very early latencies, the actual integration of individual sensory traces into an internally consistent mental representation is dependent on both top-down and bottom-up processes. Moreover, I argue that this integration is not limited to just sensory inputs, but that internal cognitive processes also shape the resulting mental representation. Studies showing that memory recall is affected by the initial multisensory context in which the stimuli were presented will be discussed, as well as several studies showing that mental imagery can affect multisensory illusions. This empirical evidence will be discussed from a predictive coding perspective, in which a central top-down attentional process is proposed to play a central role in coordinating the integration of all these inputs into a coherent mental representation.
多感官整合涉及一系列不同的认知过程，这些过程发生在感觉处理的不同阶段。在此我认为，尽管最近有研究表明多感官交互可以在非常早的潜伏期发生，但将各个感觉痕迹实际整合为一个内在一致的心理表征依赖于自上而下和自下而上的过程。此外，我认为这种整合不仅限于感觉输入，内部认知过程也会塑造最终的心理表征。将讨论一些研究，这些研究表明记忆回忆会受到呈现刺激时的初始多感官情境的影响，以及一些表明心理意象会影响多感官错觉的研究。将从预测编码的角度讨论这些实证证据，在该角度中，一个核心的自上而下的注意力过程被认为在协调所有这些输入整合为一个连贯的心理表征中起着核心作用。
