SUMMARY
The present paper proposes and argues a case for incorporating the working memory (WM) construct as a component of foreign language aptitude. As such, it first briefly reviews previous research on foreign language aptitude, which lays the ground for the proposal. Then, by drawing on recent research from both the fields of cognitive psychology and second language acquisition, the paper will summarize the key representative theoretical models, major claims and empirical evidence supporting the role of WM in different aspects of L2 learning, such as listening, reading, speaking, writing and interpreting, thus rendering the proposal a feasible blueprint for future research on foreign language aptitude.
