【 摘 要 】

In order to adjust to an ever-changing environment, our brain constantly constructs predictions for various inputs. The auditory system in particular has been shown to automatically use predictions to facilitate sequential processing. Predictive coding theories suppose that the brain extracts regularities to actively predict what is next. It is assumed that brain functions consist of a hierarchical model of predictions guided by bayesian inference (Friston, 2005); predictions coming from higher levels act as empirical priors for representations in lower levels, where sensory events are used to update the current predictions. In the end, the prediction model with the highest correctness probability determines the conscious percept.
