“预测性大脑”一词描述了认知神经科学中最相关的概念之一,它强调“展望未来”的重要性,即在各个认知领域中的预测,准备,预期,展望或期望。类似地,有人认为预测处理代表了神经计算的基本原理之一,预测错误可能对驱动神经和认知过程以及行为至关重要。本文综述了已经认识到预测重要性的研究领域,介绍了相关术语和理论,试图抽象出一些预测加工的生成机制。此外,我们讨论了测试的有效性假设的期望匹配这些实现的事件,并比较随后的处理事件,确认那些违反了最初的预测的过程。我们的结论表明,虽然很多是已知的这种类型的处理,仍然有许多悬而未决的问题,需要解决之前,一个统一的预测处理理论可以假设与认知和神经功能。
The term “predictive brain” depicts one of the most relevant concepts in cognitive neuroscience which emphasizes the importance of “looking into the future”, namely prediction, preparation, anticipation, prospection or expectations in various cognitive domains. Analogously, it has been suggested that predictive processing represents one of the fundamental principles of neural computations and that errors of prediction may be crucial for driving neural and cognitive processes as well as behavior. This review discusses research areas which have recognized the importance of prediction and introduces the relevant terminology and leading theories in the field in an attempt to abstract some generative mechanisms of predictive processing. Furthermore, we discuss the process of testing the validity of postulated expectations by matching these to the realized events and compare the subsequent processing of events which confirm to those which violate the initial predictions. We conclude by suggesting that, although a lot is known about this type of processing, there are still many open issues which need to be resolved before a unified theory of predictive processing can be postulated with regard to both cognitive and neural functioning.
