This study aims to examine the relationship between working memory capacity,along with its processing and storage elements,and different levels of EFL reading comprehension among Chinese college students.Results from a reading span task,a reading comprehension test and a retrospective interview demonstrate that:1)Working memory and its sub-elements are significantly correlated with different levels of reading comprehension;2)The processing element of working memory can significantly predict reading comprehension,while the storage element shows no such predictive power;3)The processing element of working memory has stronger correlation with and predictive power for macro-level comprehension,compared with micro-level comprehension and lexical comprehension.The findings reveal the important role that working memory capacity,especially its processing element,plays in macro-level comprehension.
