Abstract: The Concentric Model of Working Memory specifies three regions in which memory contents can be held: the focus of attention, the region of direct access, and the activated part of long-term memory. This article reviews the main research methods and the latest evidence of the model, followed by its theoretical contributions to the study of working memory, including providing explanations for the capacity of the focus of attention, the relationships between storage and processing, and individual differences in working memory capacity. Moreover, the article discusses the relationships between the model and other working memory models, namely Cowan’s embedded-process model, Baddeley’s multi-component model, and Engle’s opinions of working memory. In the end, the article makes some suggestions for further research

Key words: The Concentric Model of Working Memory, the focus of attention, the direct region of access, the activated part of long-term memory
