情景缓冲器的提出及其研究现状

The proposal and current research situations of episodic buffer

情景缓冲器是巴德利在2000年提出的工作记忆模型的第四个成分,是对其在1974年提出的工作记忆广度三成分模型的补充。情景缓冲器是一种各子系统和长时记忆之间的交界面,被认为是代表一个可以利用多重编码的存储系统。在某种意义上它被认为是一种整合的情景或场景,并提供一个在系统之间的能应用不同编码方式的容量有限的缓冲。目前关于情景缓冲器的研究主要集中在它是如何整合来自各个子系统的信息以及它在语言学习方面的作用。

Episodic buffer is the fourth component of the model for working memory proposed by Baddeley in 2000. It is a supplement to the model for working memory span composed of three components and a borderline between each subsystem and long term memory, regarded as a memory system that can utilize multiple recoding. In some sense, it is considered as an integrated condition or field and provides a buffering with limited capacity, which can use different encoded modes among systems. At present, researches related to episodic buffer mainly focus on how it integrate the information from different subsystems and their roles in language learning.
